The 2.4 liter used in the Sonata Hybrid is an Atkinson cycle engine with traditional fuel injection (intake manifold), not a GDI (gasoline direct injection).

 

Also I thought the hybrid was made in Korea..I know the 2016 is. This recall was for the Alabama plant

 

I do realize the engines are different, (ours being Atkinson) and manufactured in different plants, but have to wonder if the early production ones utilized the same technology in clearing out the oil passages in the manufacturing process.
I am curious what caused a couple of these hybrid owners' engines to seize though, and if others have seized and they were just written off as neglect on the owner's part:

One of the complaints exactly describes his hybrid's engine seizing due to improper lubrication, and Hyundai's lack of repair under warranty.
I wish the site would list the subsequent results that the complainant had with Hyundai if any at all.

We have a Hybrid seized up.. top end covered in mud... how would that be a Hyundai lack of lubrication.. the lack here is the oil turned to crap and did poor job of lubricating engine.. that owner fault, not Hyundai..

 

Of course if the owner didn't change the oil and it is proven that lack of maintenance was the cause of the seized engine then shame on that owner. But, what I am referring to is if the vehicle was maintained correctly and the engine seized because of the recall issue and it seized before this recall was announced, would Hyundai have just blamed the owner's maintenance practices and just not covered the repair and left the owner high and dry? The person who wrote that complaint doesn't mention if he/she had the required maintenance performed and no follow up is documented on that site.

 

If anyone is interested in more info on this recall of 2011-2012 Sonata 2.4 L and 2.0 T engines, you can find on this thread: http://www.hyundai-forums.com/yf-20...011-sonata-i45/414281-recall-connecting-rod-wear-may-result-engine-stall-6.html

NO HYBRID ENGINES ARE INCLUDED IN THIS RECALL.

 

This thread is an exact example of what I was referring to:
http://www.hyundai-forums.com/perfo...ct-forum-your-model/346833-2012-sonata-hybrid-engine-seized-@-38-000-miles.html

 

A thread where the poster appeared to have trouble distinguishing the difference between an engine oil pump and a transmission oil pump. An engine oil pump failure would not have brought him into the shop for transmission (hybrid system failure) problems. A "hybrid system failure" alarm could be generated either by the electrical or mechanical side of the drivetrain.

What the poster did not disclose was his oil change frequency. Without that information, I don't take much stock in that entire thread's worth.

 

Finally a recall for this problem, too many years in the making unfortunately.

December 1, 2020 NHTSA CAMPAIGN NUMBER: 20V746000
Engine Damage May Cause Stall or Fire
A damaged engine can increase the risk of a fire or it can cause an engine stall, increasing the risk of a crash.
NHTSA Campaign Number: 20V746000
Manufacturer Hyundai Motor America
Components ENGINE
Potential Number of Units Affected 128,948
Summary
Hyundai Motor America (Hyundai) is recalling certain 2015-2016 Veloster, 2012 Santa Fe, 2011-2013 Sonata Hybrid, and 2016 Sonata Hybrid vehicles. The connecting rod bearings inside the engine may wear prematurely, which over time can result in engine damage.
Remedy
Hyundai will notify owners, and dealers will inspect the engine. If bearing damage is found, the engine will be replaced. Dealers will also install a software update containing a new Knock Sensor Detection System (KSDS). Repairs will be performed free of charge. The recall is expected to begin January 22, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 198.

 

I use super gas so I doubt my knock sensor has ever worked. Now that the car is older I went to an oil one grade thicker.
5W20 is a bit thin.

 

Re Campaign 198. I got my letter today saying it is coming (not any other real info). Does anyone know what the remedy will be for this? Drop the pan and put new connecting rod bearings in?

Just got my 2nd letter today and it says to make an appointment which will take about an hour to check for bearing damage. If damage is found, then they will replace the engine, which will take about 10 hours.

 

Same here, just got my 2nd notice for my 2016. I'm curious to know how long the recall will be open and how long I can put it off.

 

I think you need to get it done before June (by May 31?) to qualify for the lifetime warranty.

 

So if you bring it in and all is good then you get a lifetime warranty? Or they replace the motor and get a standard warranty (10/100)?

 

Received my second notice on Saturday for my 2013 Sonata Hybrid. Have my appointment set for the 13th.

In the US it is for the lifetime of the engine, if it goes into limp mode or seizes after the software update.
