Saw this recall today when I entered the VIN Number for my car, Not too happy about this as it is a brand new calligraphy trim bought this year.

I advise others to check the recall status of their vehicles too

HMA Recall 236: 8 Speed DCT – Loss of Motive Power – Remedy Not Available

A “stop sale” has been issued on affected new vehicles in dealer inventory. As required by federal law, dealers must not deliver new vehicles for sale or for lease to customers until all open recalls have been performed. Dealers must perform all open recalls on used vehicles, demo, and rental vehicles prior to placing them into customer use and whenever an affected vehicle is in the shop for any maintenance or repair.

Description:
The high-pressure electric oil pump in certain Hyundai Santa Fe, Santa Cruz, Sonata, Veloster N, Kona N, Elantra N vehicles may exhibit an internal fault setting DTC(s) and illuminate various warning lamps on the instrument cluster. The vehicle enters a fail-safe mode and loses all motive power approximately 20-30 seconds following the DTC and warning lamp illumination. Disengagement of the transmission clutches and drive gears while driving leads to a loss of motive power, increasing the risk of a crash.

Affected Vehicles
  • Certain 2021-22MY Santa Fe (TMa) produced from 11/20/2020 – 03/31/2022
  • Certain 2022MY Santa Cruz (NXT) produced from 06/22/2021 – 03/25/2022
  • Certain 2021-22MY Sonata (DN8a/DN8) produced from 11/24/2020 – 03/31/2022
  • Certain 2022MY Elantra N (CN7N) produced from 09/15/2021 – 04/08/2022
  • Certain 2021-22MY Veloster N (JSN) produced from 08/28/2020 – 05/13/2022
  • Certain 2022MY Kona N (OSN) produced from 10/05/2021 – 05/04/2022

I just completed a 1600-mile trip and just found out about the recall. I checked vin # and I am also under the recall.
During my trip, the car had no problems and shifted beautifully, and averaged 27.4 mpg (gas + miles)
Called the dealership this morning and left a message to call me on what next is to happen.
Has anyone in this forum had this type of failure?

Follow-up
The dealership returned my call and the service mgr. wanted me to take a picture of the S.F. and mileage and send it to him. The car will stay at my home and they will set up a rental for my use. No, fix yet so no reason to leave it at the dealership till the problem is solved. The manager was professional and courteous.
I will keep you informed when more info on repairs

The recall is now up on the NHTSA's site under recall# 22V746000. Apparently, 53,142 vehicles are affected.

The listed remedy is:

Dealers will inspect and replace the transmission, as necessary. Dealers will also update the transmission control unit software. All repairs will be performed free of charge. Owner notification letters are expected to be mailed December 5, 2022. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 236.

Interesting. Reading more into the file. Looks like the NHTSA forced the recall on Hyundai. Definitely not a voluntary recall...

On September 21, 2022, NHTSA’s ODI inquired on certain VOQs for model year 2022 Hyundai Santa Cruz vehicles alleging a loss of motive power event(s) while driving at various speeds. NASO reviewed the VOQ’s and began analyzing the VOQ’s combined with HMA’s internal field quality data.

On September 22, 2022, HMC provided NASO its VOQ analysis and findings surrounding probable cause. HMC informed NASO that the loss of motive power condition may be caused by the vehicles’ 8-speed dual-clutch transmission (“DCT”) or associated components.

On September 28, 2022, NASO provided an overview of its full analysis to NHTSA’s ODI during its monthly recurring review of top safety topics. NASO informed ODI of HMC’s assessment identifying an internal fault with the DCT’s high-pressure electric oil pump as the likely cause of the vehicle entering “fail-safe” driving.

Based on the information received from HMC and prior discussion with ODI, NASO convened its North America Safety Decision Authority (“NASDA”) on September 29, 2022 and decided to conduct a new recall of affected Hyundai vehicles in the U.S. and Canada to address the defect condition involving the transmission “fail-safe” drive mode.

As of the date of this filing, Hyundai has confirmed 229 unique incidents received from June 1, 2021, through September 26, 2022, in the U.S. There are no confirmed crashes or injuries related to this condition in either market.

You all should have shown up at dealer today for recall updates.. Everybody can get logged into tablet and GDS, but as soon as you try to enter UPDATE window, it cease operation with pop up stating user authentication error,, I called Hyundai contracted vendor 2x yesterday, no call back yet, fella says he called last week, and no call back to him,, we have 1 sitting all day, suspect they put them in a car.. my day ceased 4:30, cant get in to check PCM ROM for 2nd vers of the 953 update, or to do the smart junction box / turn signal update

Yep looks like it will just be a software update based on that article. Also seems like vehicles from April and May 2022 already had that update.

"Dealers will be instructed on December 5th to inspect the eight-speed transmission and – if necessary – replace it. Dealers will also reprogram the dual-clutch transmission’s control unit with updated software that provides better fail-safe driving capability. Hyundai says the revised software logic in the control unit was implemented in production in April and May 2022."

Autoweek's article is confusing. It says Hyundai is recalling the impacted vehicles as well as stopping sales of vehicles with DCT transmissions. If only a subset of DCT transmissions were affected, then why stop the sales of all DCT transmission models? This comes at a rather unfortunate time for the company while it is working on a fix for its cars without immobilizers, and news of its dealers charging upwards of $700 for the fix while customers suffer from anxiety of having their cars stolen with an iphone cable!

KIA's recall for DCT happens to provide some more details to the failure than hyundai:

Description of the Defect:
The electric oil pump within the 8-speed dual-clutch transmission (DCT) may experience an internal fault due to a quality deviation issue at the supplier. As a result, the subject vehicles may set a diagnostic trouble code with warnings and allow the vehicle to be driven normally for 20-30 seconds, followed by complete loss of motive power due to disengagement of the transmission drive
gears.


How Remedy Component Differs from Recalled Component:
The remedy transmission has no electric oil pump circuit board quality deviation. In addition, the transmission control unit contains updated software.
 
#82 ·
Hey, just read this recall, out of curiosity. And I'm more confused now if my 04/09/22 might also have a defective HP pump. Kia lists the defect being rectified in AUGUST, not April. Why such a drastic difference in dates? Does that make sense to you? I know both have the same parent company, so makes no sense Kia fixed the issue 5 months later. Oh, and this recall says only 1% of vehicles were affected, which makes a lot more sense than the 100% figure on Hyundai's recall. What a mess.
 
#77 ·
Looks like the issue from the supplier is specifically related to the circuit board of the electric oil pump. So not the electric oil pump itself or more importantly any issue with the transmission as a whole.

However to what extent of damage a faulty circuit board in the eletric oil pump will cause to the transmission itself is yet to be determined.

Hey, that was great information; thank you very much. But still not clear if new pumps don't have that circuit board, or have it better attached. At any rate, looks like that circuit board issue can cause the pump to 'fail' somehow at any time. And on a DCT tranny, any issues with the high-pressure needed to shift gears, could crash the gears and ruin a perfectly fine transmission in short order. But where is that circuit board? Inside the pump, or inside the transmission? I'd have liked to see more transparency on why transmissions were being replaced due to HP EOPs. I suspect there are preise calibration issues as well, that need specialized equipment dealers don't have, so the factory might fix those transmissions, and reinstall on affected vehicles. Would like to know more about that too. Hopefully later on.

Now, what about folks with post-recall SFs, like me? Does that mean our SFs only have the updated software, or also the updated pump/circuit-board as well??? No word on that. Really hope the latter, because that'd finally make me feel at ease of not being affected. But we'll have to wait for info on that, I guess. Oh, and what about the TCU update Hyundai did too? I only know of a shifting TSB affecting my tranny, but maybe April+ SFs like mine already have everything good with the tranny; it'd be nice to know :).

Just had the software update for the transmission recall on my 2022 Santa Cruz. Before update I noticed a little weirdness on occasion in sport mode with staying in a higher gear way to long after braking. In normal mode it was also slow off the line so I used sport mode if I wanted to take off fast or change lanes in traffic. After update I now have a highly messed up transmission. Jerks off the line enough to hurt my neck. I brought it back in and they redownloaded the update and bled the tranmission. It is now worse than ever. Car took three pushes of the start button this morning to start. I comes off the line very slowly than surges forward suddenly. Jerks badly when going into reverse and just feels dangerous to drive at low speeds. After two service appointments I have no confidence they know how to fix the problem and what in the world does a software update have to do with a curcuit board problem. Hyundai has a hot mess on their hands at the moment and I may have a $$40K lemon on my hands.
 
#87 ·
Oh man; sorry to hear that. I think the software update has nothing to do with the recall, but with shifting complaints. My SF is included on that TSB, but mine shifts perfectly acceptable, so no way I'd risk getting it worse. The only trait I don't like is the clutches open before they should, so it's hard to 'crawl' smoothly. And the engine surges a little at low rpm, but since I hardly ever drive in traffic, it's not a big deal at all. I cleared the recall, but still not sure my tranny is defect free or not, since we don't know much about the other oil pump issue, and Kia reported the HP pump recall on August production, rather than March for Hyundai, which makes no sense. So following this thread with interest :).
 
#89 ·
No, maybe with a recall, but not a TSB, which is supposed to be an internal document owners don't know about. Hyundai obviously did numerous software updates, where my Apr '22 built SF probably had the second last, so those owners are more unlikely to complain. Anyway, where everything is going to **** IMO is the step to 'bleed' the transmission, where most techs probably don't know how to do it, or don't have the proper equipment. And I'm 100% convinced the only dealer in town would mess it up too. If you have to take your vehicle for service and instruct them not to perform that TSB, they'd have to comply. But if it was a recall, they'd have to do it by law.
 
#91 ·
Oh yeah, I'm sure there's no way around that, unfortunately. But hopefully Hyundai will provide a better fix than the current TSB, which seems to make matters worse, probably due to dealer/tech incompetence. Frustrating. Hope mine never has to touch a dealer after I bought it. Ha ha. Every time I've had to do that something got messed up. Last time they chipped and dented my fender, and tried to pretend it was there already, but I took pictures right there. The fix was a disaster, and had to sell the car (an Azera Limited).

Not sure where this fits in but looks like Hyundai-KIA will take a significant financial hit this year due to warranty repairs.

Hyundai Motor and Kia warn $2 bln engine provision to hit Q3 earnings

SEOUL, Oct 18 (Reuters) - Hyundai Motor (005380.KS) and affiliate Kia Corp (000270.KS) will book a combined 2.9 trillion won ($2 billion) provision in their third-quarter results as they continue to suffer the effects of engine recalls from years ago, they said on Tuesday.
The costs, of which Hyundai accounted for 1.36 trillion won and Kia for 1.54 trillion won, amount to more than half of Hyundai's estimated third-quarter net profit and 77% of Kia's profit, Refinitiv data shows.

The provisions are due to an increase in the number of engine replacement claims as more U.S. customers have opted to drive their old cars over buying a new one amid tight vehicle production caused by a global chip shortage, the South Korean group said in a statement.
Hyundai and Kia, among the world's top 10 automakers by vehicle sales, recalled nearly 1.7 million vehicles in 2015 and 2017 in one of their biggest recalls in the United States, citing a problem with their Theta GDI engine that raised the risk of crashes.
After the recall, the duo offered an unprecedented lifetime engine warranty as part of efforts to improve their tarnished reputations.
Korea Investment & Securities analyst Kim Jin-woo said the provisions - unlike a recall - were unlikely to have a major impact on the firms' brand value and credibility, and described the cost as "reasonable" given it factored in the post-COVID trading environment.
APOLOGY
"We sincerely apologise for repeated quality issues and additional costs related to the Theta II GDI engine recall," Cha Seong-ju, head of the quality division at Hyundai Motor Group, told analysts.

"We will put our utmost efforts to secure engine quality... and manage quality related cost in order to prevent a repetition of quality issues."
Hyundai said it had raised provisions to reflect new engine replacement claims that are running ahead of its previous forecasts due to a rise in the overall lifetime of passenger vehicles.
The lifetime of U.S. passenger vehicles grew to 13.1 years this year from 12.4 years in 2020, according to S&P Global Mobility.

Only customer pay is an oil change and brakes anymore. Everything is warranty, engines backed up in shop to be installed, add on couple more a day towed in , then wait to be look at,, PA monkey business, used to be if it was knocking or seized,, replace it, not any more. Labor warranty times been chopped like nobody business, engine replace down to 5.2hr maybe, they act like they do favor adding 1hr for diag / paperwork,, when we got 8-9hr for long block... they done cut fwd transmission down to 3.5hr avg, that r&r with diag, and doing tablet stuff after install for set up.. they don't want to pay diag, techline is a joke, can't get help from fse, stories I heard is only a couple fse any more.. dealer mechanics being paid minimum wage for warranty work.. hear lots of people bail for better pay

Hyundai engineers design shït engines, said shït engines fail, Hyundai has to pay to fix all of those shït engines yet pays the techs garbage based on unrealistic flat rate repair times, techs get pissed and leave, backlog at dealership service gets worse, customers get increasingly frustrated with Hyundai and decide to look at other manufacturers for their next vehicle.

Hyundai is reaping what they sowed with that dog-shït Theta II design they shoved in every vehicle imaginable.

It’s a shame, because Hyundai’s tech is fantastic, probably class leading IMO. But they can’t seem to design a reliable internal combustion drivetrain to save their lives.

According to Hyundai, it should have been fixed since 03/31/22 production, but I have my doubts. Mine barely cleared with 04/09/22, but the recall is just for the HP oil pump, when they were having issues with BOTH oil pumps. Then the recall doesn't say if it's just for the software portion, or the defective circuit board too (which Hyundai never mentioned). Adding further doubt about my SF is Kia also said they fixed the transmission issues until AUGUST, so 5 freaking months later than Hyundai. That makes no sense to me, so waiting to see what happens with other SFs closer to mine in build date. That's the only way we're going to know, apparently. I didn't save the Kia recall, but it's linked somewhere on this thread. I'd go with that build date as a sure way to know it should be defect free (at least from this recall). Or if you don't want to search for it, buy one that has a production date newer than Sep 01, 2022, and you'd be good :).

I'm confused by the 'Theta xx' classification. Isn't our 2.5/T a Theta 3? And which was Theta 1? I have a 2.0T on the 2023 G70, which I guess is a Theta 2, no? I had the same engine on a 2016 Optima SX-L which felt more powerful than the G70, but was affected by the con-rod fiasco. If the 2023 is still a Theta 2, which I believe it is, hope it's not defective.
 
#102 ·
Any 2.0T from Hyundai/Kia is a Theta II. THE 20T used on the 2019/2020 Santa Fe is a Theta II. The new 2.5/2.5T engines using from 21+ are Theta III.

And as for the 2.0T in the G70, I personally wouldn’t have gotten it for the sole reason that it’s a pretty underwhelming turbocharged 4 cylinder engine, the 3.3T is much more refined and sporty. And only time will tell if the 2.0T in the Genesis products be fail like the ones used throughout the 2010’s decade. But the oil starvation issue seems to be design, not manufacturing related (a manufacturing issue would not go on for years and years and years like a fundamental design flaw would), which wouldn’t make me feel great if planing on owning the vehicle beyond the warranty period (it’s one of the reasons we sold our 2019 2.0T ultimate and got a 2021 2.5T Calligraphy).
 
#103 ·
So which is the Theta 1? Just curious. And the 3.3T engine is not that refined IMO (just like the 2.0T, both being quite old), but the new 3.5T is, just like the new 2.5/2.5T. Not German refined, but much better. I used to have an Azera with the 3.3 NA, and had to sell it by 30K miles, as it was sounding horrible, especially when cold. I blame a lot of that on the upside-down oil filter, but a lot of other problems popped up on other cars too. So I had issues with both a 2.0 and 3.3, but was willing to give Hyundai/Genesis a 2nd chance. Bought a 2022 G70 3.3T Sport Prestige, and awful engine noises by the time I pulled into my garage, so returned the **** thing; no more 3.3s for me. Waited for the 2.0T, and so far it hasn't given me issues in 2,500+ miles, but the performance feels well below the 2016 Optima, when the RWD G70 is only 100 heavier... which should be offset with the 8-sp tranny (vs 6). Makes no sense. Oh, and it's listed at 252/260 with freaking premium, when the Optima had 245/260 with regular. So now I put regular on the **** thing, and can't feel any difference, but still below the push the Optima used to provide. Oh well. It still has decent performance, but it doesn't feel like a sporty sedan at all. Ha ha. Hope both vehicles (SF and G70) don't give me any mechanical issues, but we'll see. So far I haven't seen any failures of recent SFs like mine, which is nice.
