But we already went through the connection bearing recall, are they different? Both recall ask for software update on knocking sensor.

 

The car runs great. For the people who had their engine replaced, where they always symptoms? Some info that I found -

On my 2011 Sonata Hybrid I did not have any symptoms before my engine failed. It was running great and I gave it a little more power to change lanes and the engine gave up right then and there.

 

I brought my car in for the 966 engine monitoring logic. He said it passed so I don't need an engine. I asked what they will do if something happens in the future, he told me Hyundai has been good to work with and it is a known problem. I'm not too confident about that answer. It would have been nice to get a free engine at 123K miles but I'm also glad I don't need it. Taking things apart sometimes leads to other problems.

 

I have yet to get the software update. Can you tell me what happened with you? Did you get the update and also was your engine examined and determined that you dont have any issues with your engine?

 

I'm waiting until the last minute to bring mine in for the check/recall:
1. Because as mentioned this is a big deal to replace a motor, and don't really want other things in the vehicle messed with or messed up.
2. It doesn't seem that Hyundai or dealers really know how to handle or even have replacements if it comes back as needing one.
3. The vehicle shows no signs of an issue (yet).

 

So y'all are getting me a little bit worried here. I'm looking to buy a 2013 Sonata Hybrid and in looking at the Carfax I saw these 2 "Manufacturer Service Campaigns". The car has low miles (45k), but it's out of warrantee. I'm concerned if the engine does fail whether or not it would get fixed or replaced. I suppose I don't really understand how these things work. I appreciate any feedback that you can provide.

 

I rebuilt one this year and IMO the complexity of the Hybrid is unwarranted and gives little added value. That car though (2014 model year) was mint but I still wouldn't sell it to my daughter-in-law:, who needed a car, knowing that any repair could entail much higher cost. The last time I checked the service campaigns the two outstanding were pending, not yet operative.

 

I was holding-off on 953 because I heard of the nightmare scenarios: update, limp-mode, knock-sensor, KS-harness...engine replacement! I had it done because it's required in the legal-ease for continued engine warranty.
I have not notice anything different except shifting...and that may have been a "re-learn" side-effect of the process.

 

Hello! I am very interested in this thread. We just purchased a 2012 Hyundai Sonata Hybrid from a private owner whose daughter we know.
61k on it. My daughter has it 18 days, it squealed, smoked (from serpentine belt) and the problem with hybrid system do not drive came on. It’s at the dealer and they are trying to show there is bearing damage to get the engine replaced. They asked my daughter’s permission to open up the engine today so they could prove there is a bearing issue, because what ever other test they did, Hyundai said it wasn’t the bearings. 2 weeks. We had this car 2 weeks. My daughter spent her own saved money to get this car after being rear ended and having her other car totaled. Pray to the Hyundai gods that this repair is covered.

 

Interesting. Hyundai issued a new bulletin at the end of October to update the knock detection software: https://static.nhtsa.gov/odi/tsbs/2021/MC-10203282-0001.pdf

Updates To This Document
TSB Update # 21-01-023H-3 for adding additional models:
1. 2010 MY Santa Fe (CM) 2.4L
2. 2014-2017 MY Elantra GT (GD) 2.0L
3. 2016-2017 MY Sonata Hybrid & Plug-in Hybrid (LF HEV/PHEV) 2.0L
4. 2016-2017 MY Tucson (TL) 2.0L

I just ran my 2016 VIN and even though the dealer said my car passed the test a couple of months ago, the recall 966 still shows as Incomplete.

 

This might be a huge coincidence but it seems like my mileage has increased since the car went in (ECU refresh?). I was getting around 520-540 miles out of each tank. Now it's in the 580-620 range, My driving style has remained the same.

 

My call has two service campaigns. One is to replace the auxiliary canister and the other is 966 -

Hyundai Motor America has issued a recall for 128,948 of its vehicles, including the 2012 Santa Fe, the 2011 to 2015 Sonata Hybrid, and the 2015 to 2016 Veloster, for connecting-rod bearings in the engine that could wear out prematurely and damage the engine, according to the National Highway Traffic Safety.

Looking at campaign 953, it says -

The software is designed to alert the vehicle driver at an early stage of bearing wear before the occurrence of severe engine damage, including engine failure, and enable the customer to safely drive their vehicle to a Hyundai dealer for inspection and repair.

Before I looked these up, I was under the impression they use the software in Campaign 953 to listen for signs of bearing wear to determine if the engine should be replaced. Reading the info for Campaign 966, it sounds like they are more likely to replace the engine.

Any feedback from owners who have had their car in for one of these?

Thanks!

I’m still confused as this doesn’t really seem to highlight the differences between Campaigns 953 vs 966. My 2012 Santa Fe had Campaigns 198 and 966 supposedly performed. I say that because the dealer outright lied to me about overheating issues I was experiencing. Hyundai America was useless and did nothing but stall. Eventually after 6 months I was able to get the dealer to replace the defective radiator they installed, replace old hoses and clamps they reused. As a goodwill gesture they also replaced the thermostat that I’d originally told them I thought was the cause for the overheating. Yes that actually solved the problem. Jack

 

I brought my 2014 Hyundai Sonata Hybrid in for the 964- AUXILIARY CANISTER INSTALLION & 966- ENGINE MONITORING LOGIC Service recall campaigns on 12/08/21. Today, 12/21/21, in heavy traffic on the highway, my car engine abruptly shuts off, immediately decelerating, completely losing any ability to accerate while the engine light, parking break light come on along with an "electric motor warning - safely pull over and do not drive" message on the dashboard. All this happens while a high pitch alarm goes off. All happening simultaneously without warning on the highway with vehicles surrounding us driving 70 mph! This has never happened prior to today and should never happen. How we managed to avoid an accident or worse was a miracle. This was life threatening and should not be taken lightly!

 

that's about what happened to me but there wasn't any warning that I was aware of. Lost RPMs and coasted into a parking lot. 2014 Hyundai Elantra GT. Do regular oil changes and I think I've had the car about two years. Discovered the battery wasn't the right size while trying to identify what was wrong. Mechanic told us to have it towed to the dealership because it must be throwing codes telling her it's related to this bulletin. She told my wife the engine is seized up. That's probably going to cost 90% of the car's value to replace and I'm not sure what happened. There wasn't any service indicator. I didn't see anything while I was driving to warn me it was about to shut off. It's been a good little car but I think it's a $12,000k brick now. If 3/4 of its value when I bought it is needed to repair it then I'll scrap it and start over.

We did our homework before buying it and I don't remember any of this in the lemon-aide guide. We also have a 2015 Toyota Sienna and I went online and made sure there weren't any open service bulletins because I'm going to be paranoid about this stuff. It sounds like some of us were lucky and some of us weren't. Wish me luck fixing my 12k dollar brick or replacing it.

 

I have a 2011 Santa Fe. I'm wondering if the damage is already done as the engine doesn't seem to run like it used to. Idle is rough and it makes a weird sound when accelerating. This does not go away as the engine comes up to temperature. We've been good with oil changes and the like.

 

Just receive the 966 campaign today. The previous campaign 953 was taken in a month ago and they could not perform the service. Interestingly enough we have worse gas mileage now since the other campaigns were fulfilled. We were getting 42 to 45 miles per gallon now we're down to 38 to 35.
So now I guess we wait for the 966 campaign and hope that they can fix them both at the same time. I have a 2017 hybrid sonata and we have enjoyed this vehicle thus far. Hoping that continues.

 

I brought my 2014 Hyundai Tucson in for the 966 recall on February 10th. From my understanding they updated the software to make the Knock Sensor more sensitive to engine vibration. Therefore, if there is premature wear/damage to the connecting rod bearings the knock sensor will sense the issue and warn the driver. Two days later on February 12th, I was driving and all of the sudden my check engine light was flashing and my engine shut off of and I had no control of the gas pedal. This is known as limp home mode (a mode that lets the driver get off the road safely). Brought the car to a dealership, they tried to reinstall the software, but that didn’t fix the issue. They did a bearing test, and the car passed the test. Now they think the Knock Sensor needs to be replaced. We’ll see what happens.

 

I had the exact same issue occur with our 2015 Hyundai Sonata Hybrid. What was the resolve for you?
We already had the engine (theta 2) replaced under the first recall and the dealer is saying that they already preformed a "bearing clearance test" and it passed. This means the engine warranty is not on them because the updated knock sensor is stating the issue is coming from the top end of the engine and not the short block side which is covered by the warranty. Doesn't make sense to me but am really caught in a hard position because I need a vehicle.

 

I keep receiving letters and phone calls to bring my 2016 HSH in for the programming... Not sure this is a fruitful thing based on what I'm hearing. Don't want to see efficiency go down as well. I can currently get about 55 mpg on average driving easy. Wondering how long I can hold out on this "recall" as far as the time frame they are allowing?

 

I have a 2014 Hyundai Elantra GT that lost RPMs on a highway and I had it towed home and then to a mechanic once one was selected. My wife and I are religious about oil changes with our vehicles. didn't know about any open service bulletins before something happened. The mechanic said the engine is seized up and that the open bulletin and this might be related. I'm not seeing much data on the 2014 Elantra GT but I see there's a variety of vehicles being recalled with theta engines so maybe the problem is bigger than they want to admit and they are trying to find the vehicles that have an issue by using the software update?

reading this forum it looks like there's a large issue here and being called in for an update and then having the vehicle go into "limp home mode." indicates they know but were not prepared for the severity of it. Not the first owner obviously so I don't know it's history. It had a hurricane battery in it that didn't fit the battery compartment. It was suggested I check the battery and the battery was not holding enough charge to start the engine. the vehicle wasn't there and running so I couldn't have it plugged in at the auto-parts store to see the codes. When it broke down it was very hot, there was some smoke, and when I tried to start it there was a repeating pulse through the whole system. wish I had known sooner that the battery wasn't to spec but they had this black insert in the compartment and it never caught my eye. It was sold to me with the wrong battery so I might be experiencing an issue that isn't common for this service bulletin. My gut says it started as an electrical issue and became an engine issue. Literally all I know is the indicator lamp blinked briefly as I was driving then I was coasting with no power.

the benefit of the software update is for the car to put itself in a "protective mode."? The problem is there wasn't any feedback from the vehicle on what was happening. Maybe a newer model would have had an electrical monitor. used to have sprint drive in my car and when logged in you could see the voltage, oil temps, and other stuff available through the OBD-II port. suspect I might have known sooner if I still had that thing running. network service was not good at my last job so I changed providers. still have the device but I'm not sure how to use it without logging in to sprint's website. Own it even if it isn't on the network anymore.

 

People...I know that this is a semi-old thread, but I am posting as a warning.

We have a 2016 Sonata Hybrid. 2021 there were 3 recalls issued:

1. 1 for an emissions sticker (the car might now pass emissions with the sticker from the factory)
2. 1 for a new hose or a new belt (or something similar, I don't remember)
3. 1 for possible engine failure due to the rods

Car went in to dealer June 2021. Items #1 & 2 no problem. Item #3 involved a stress test. What happens if the car passes the test: you all good, no new engine needed. Car fails? new engine needed courtesy of Hyundai. Our car passed...Yay (I'd rather have a new engine put in)

Labor day weekend...Road trip: 330 miles. Friday night 9/3 roughly 7:30pm and 200 miles into the trip (57,000 odometer miles), car starts flashing warning light: LOW WASHER FLUID. this warning continues for about 30 minutes, becoming more and more frantic (mind you, we are in the middle of no where and NOT using our washer fluid at all). Roughly 8:00pm, the car starts making a lot of noise. We are on a rolling highway (Route 17 NY). Family of 4 starts to debate about WTF the noise is. Maybe something came loose on the front of the the car? Climbing up the next hill...noise get really loud and then BANG! car is dead...engine seized.

Fast forward 3 months and a lot of headache...we finally get our car back mid-December 2021. The alignment is off, the tranny has a problem, and the check engine light is one. I am 200 miles from home, and NOT leaving my car there again.

Fast forward 3 more months, I have since gotten my car repaired at my local mechanic, and submitted for reimbursement of expenses (car rental, hotel stay, post-engine replacement mechanic work, etc). Hyundai called me yesterday (March 18 2022). Blah. blah. blah...can't pay for hotel...blah blah blah...we'll see about the other items....oh, "and I see that you have 2 outstanding recalls on the car, you should get it to the dealer ASAP". I explain that I had 3 recalls in 2021, so does this mean there is # 4 and #5? He confirms yes, recalls #4 (210) and #5 (966). Recall #5 sounds exactly like recall #3, no?

So now what? I have to bring the car in again, lest the engine blow up. Fine, pain in the a** but whatever.

There is no "moral of the story" here. Just giving you info to decide on how you handle things.

FYI: Engine warranty has been extended for all recall related cars.

FYI#2: all cars could have problems. Don't get me started about our 2013 Prius, when it wouldn't drive more than 10 MPH, sat at the dealer for 30 days with them clueless, 15 more days after they replaced multiple computers, and then later that year a giant recall for a computer problem that makes the Prius stop driving (yes, we were part of the few that helped them figure that one out).

 

Hyandai now has had my car for two weeks. They confirmed it's the engine issue under 966 and we won't be charged for the repairs. Beyond that I don't know much other than my odd experience when it stopped working.


Thanks for sharing your experience with was different alerts but sounds like the electronics were again aware it was the engine but not telling you it's the engine.... I used a guidebook also when looking for a used car and unfortunately this peculiar issue wasn't in it. engine recalls are not fun for anyone.

 

I had the exact same issue occur with our 2015 Hyundai Sonata Hybrid. What was the resolve for you?
We already had the engine (theta 2) replaced under the first recall and the dealer is saying that they already preformed a "bearing clearance test" and it passed. This means the engine warranty is not on them because the updated knock sensor is stating the issue is coming from the top end of the engine and not the short block side which is covered by the warranty. Doesn't make sense to me but am really caught in a hard position because I need a vehicle.

 

Got my Hyundai Tucson back!
Just to recap, they did the bearing clearance test (which the car passed) and replaced the knock sensor, although the check engine light was still coming on because the knock sensor sensed abnormal engine vibration. They performed another bearing clearance test, and it passed that one too.
Fast forward a couple weeks.
They performed a top engine cleaning, to remove any built up carbon or other contaminants. I’ve had the car back for about a week and she’s running smooth again.
It was a lengthy (4 weeks)and relatively stressful process, but I am happy and grateful to have my vehicle back and running.
Hyundai had me pay for the knock sensor replacement, but they covered the cost of the engine cleaning. So in total I paid for a rental car, until they were able to provide me a loaner, and $500 for the knock sensor replacement.
I’ve noticed through reading this thread that some dealerships are doing things differently. According to my dealership they followed every step in the book and eventually called Hyundai corporate for follow on instructions (ie. performing the top engine cleaning).
Hoping this car lasts me another year or so, and then I’ll probably get a Toyota.

 

I am not sure the MY of your Tucson but you should check the NHTSA website to see if your vehicle qualified for a new knock sensor during one of their (many) "product improvement campaigns." You may be entitled to a reimbursement. Also not aware of all the specifics of your car troubles but I would reach out to Hyundai Motor America and explain your situation to see if you might qualify for and apply for reimbursement under one of their recall campaigns or class action settlements. They may offer reimbursement for the rental car as well.
Good Luck !

 

Update: After I wrote the previous post I was driving home from work and the engine gave out on me…again.
Back to the dealership.

 

Oh my... That's terrible! Does the engine seized? Or just stalled without any sign or warning lights?

 

I have a 13 Tucson I received the recall letter regarding Campaign 966.
I do regular maintenance on it and take great care of the vehicle. Its at 136k miles on it. On Easter the engine gave out, i thought i had a tire going down so i coasted to the shoulder as quick as i could. No warning lights or any lights lit up.
Got out and inspected everything heard a loud knocking in the engine block and had to have it towed to the dealership. Car is currently sitting at the dealership for another 3-4 weeks before they can look at it and diagnose and submit the recall. And then who knows how much longer before i get it back. They will not help with a loaner until the car is in the shop. Such BS. Car is paid off next year too … going with a Mazda or Toyota next. Absolutely terrible service from Hyundai

 

UPDATE 5/13 Still no car have been waiting for it to be take in. Will call dealership again today to see when it will be looked at.

 

It seems Hyundai can't keep up with the gas motor issues or the hybrid battery pack issues to warranty or replace. WTF. Their warranty seems like false advertising. "We are willing to advertise it, but cant honor it really".

 

The 5th time took the car back to dealer after 966 campaign. They called auto tech line did a “top engine cleaning” which I read they did for someone else on here too. That led to (1 week later) going back to dealer for 6th time needing new spark plugs and ignition coil. we e had the car back for just over a week. Keep ya posted.

OK

 

Ok, I have a HUGE Concern and Question....I Own a 2016 Hyundai Tucson SE 2.0 with the his N Hers shifter, my has always been taken to Hyundai for fluid services, oil changes etc.. ALL Maintainence done ... Everything Kept on the Up N Up as far as keeping my car "Serviced". I'm the ONLY driver, female and I do NOT abuse or "play" with vehicles. I drove the car the way it should be driven, always checking my fluids, full under hood-- Engine/Mechanical inspections myself to make sure everything is as it should be on my car. I know Hyundai has many, many Recalls and MY HUGE $6,000+ NIGHTMARE HAPPENED IN SEPT. 2020, LITERALLY IN AN INSTANT WITH ABSOLUTELY NO TYPE OF PERFORMANCE ISSUE UNTIL THE MOMENT IT HAPPENED, ABSOLUTELY NO MECHANICAL INDICATION, ABSOLUTELY NO VISUAL OR PHYSICAL SIGNS OF ANY TYPE OF ISSUE , NO TYPE OF WARNING LIGHTS/ DASH LIGHTS, NO FLUID LEAKS, NO TYPE OF NOISES, NO MECHANICAL COMPLICATIONS IN PERFORMANCE, ABSOLUTELY NO SIGN OR ANYTHING .....THE DAY MY 2016 HYUNDAI TUSCON BECAME A NIGHTMARE, PHYSICALLY AND FINANCIALLY... I HAD DROVE 18 MILES TO THE NEXT TOWN OVER TO RUN SOME ERRANDS,ON MY WAY HOME I STOPPED FOR SODAS AT THE CONVENIENCE STORE, I HAD OTHER PASSENGERS WITH ME, SO I LEFT My TUSCON running ,as I exit my car... I hear a very loud knock coming from under the hood, I immediately pop the hood and tell the guy that was with me, because the knock I was hearing made my car literally sounded like it was out of oil, and I had just had my car at Hyundai a few days before for an oil change long story short after contacting AutoNation getting the diagnosis they have found that my car threw a rod and needed engine replacement, I inquired about recalls made several complaints because I had not done anything to be the fault of engine failure and I was told that there were recalls on the engines but they were VIN number specific and my VIN did not come up in one but now I see that there were several recalls and I really feel like my car should have been one and the Hyundai should have taken care of it and now the current recall 966 but to shorten this whole conversation it cost me over $6,000 and I was wondering does anybody have any input on what I should do because 20/20 I had engine failure because of a rod and bearing and now I see this recall please if anybody has any insight on what to do let me know because my car is scheduled to go for this recall repair June 9th at AutoNation and I'm wondering if I shouldn't contact the lawyer because it cost every $3,000 for a remanufactured motor and over $3,000 in repairs at AutoNation Hyundai and now two weeks ago I had went to Georgia and my car is extremely slow to accelerate from a stop position

 

Sounds like you could get reimbursed for the cost of original motor failure. You're not the original owner and bought it from Autonation? Hope you kept all your receipts and diagnosis paperwork.
