Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

On my way to work I had turned off the highway onto a side street and my vehicle stalled out with no warning or warning lights. I coasted it to the side to safety. When I tried to restart it did and no warning lights showed up but when I went to accelerate it stalled out again. I had the vehicle towed to the dealer, waiting on an answer but sounds like it may be part of an engine recall. This could have been a fatal failure if it happened on the expressway or in another traffic situation.

A D V E R T I S E M E N T S

After acquiring this brand new vehicle in 2012, Hyundai Sonata 2012 2.0T limited, the vehicle failed and lost all power just before its first oil change. I called the dealer, O'brien Hyundai dealer as an emergency as the vehicle was malfunctioning and lacking of power to use it and I was on the road. I managed to get to the dealer. This happened approximately 2500 miles only. A quick patch or adjustment was performed at the moment. The patch just lasted several weeks as the vehicle was not performing as when it was bought 2 months ago. Since then, I have been in the dealer multiple times and quick adjustments have been performed. I left the vehicle several times for a full inspection and dealer claimed that vehicle is in working order. I tested vehicle with the shop supervisor, jim haas, with the mechanic and, of course, they are always right. This vehicle is equipped with 270 hp and after the failure, the vehicle performs as 100hp at the most. After numerous attempts to get the issue fixed, I demanded to replace the wastegate controller, just to discard issues with the original unit, and today, 4/9/16 the vehicle came with a P2565 error code, related to the turbocharger wastegate controller. I am sick and tired of dealing with such a lack of interest from Hyundai and authorized service providers. I am just banning this brand for life. I am just waiting to return this lease and run out such a bad experience with this car dealer.

The contact owns a 2012 Hyundai Sonata. The contact stated that the vehicle stalled without warning. The contact had to coast the vehicle over to the side of the road and was able to restart the vehicle. The vehicle was taken to an independent mechanic who diagnosed that there was a catastrophic motor failure and that the dealer needed to provide a repair. The contact later received notification of NHTSA campaign number: 15V568000 (engine). The vehicle was kept at the dealer for longer than two months. The dealer replaced the part for the recall repair, but the failure recurred. The contact was informed that the motor and starter needed to be replaced. The manufacturer was notified of the failure. The failure mileage was not available.

Nov. 2014 while accelerating down the highway at 70mph the motor of my 2012 Sonata suddenly seized without warning. Narrowly avoiding an accident! after hours on the side of the rode it was finally towed to the local dealership where the car was purchased. Note this happened at 104,000 miles, Hyundai certified mechanics stated that the vehicle was out of warranty and that the"seized engine" was due to lack of maintenance (which was a blatant lie) they informed us that it would cost between 5-6K for a new engine or offered to buy the car for a fraction of what was owed on it; which was a joke. After months of the car sitting in my yard and doing non-stop research, I noticed that there were other people in the same boat as me. I contemplated on buying a used engine for the car but that would've just put me in the same situation down the road. My mechanic stated we could rebuild the motor after going through the oil pan and seeing with our own eyes the #2 bearing seized onto the crank/rod. I knew there would eventually be a recall due to hundreds of people having the same issue; so, I opted on patching the engine with a new bearing with the same damaged crankshaft, rod, and cap and wait for the recall. Sure enough a year or so later I get 2 letters informing me there was a recall campaign 132 and that I needed to bring it in for the "sound" test in which it passed"??"!!! now Hyundai is refusing to replace the damaged motor saying their hands are tied and that they did everything NHTSA requires them to do... the only way to properly test that motor is by removing the oil pan and visually inspect every moving part that could've been damaged by the metal left in the rod bearing journals. What blows my mind is that Hyundai has proof that this engine was damaged by the recall but refuses to stand behind the recall and/or their product especially with it being a safety issue

I was driving on a 6 lane city road.. I got in a left hand turn lane. There was a car in front of me. The light was red. When it turned to a green arrow., I pushed on the accelerator to go and the engine had stalled. I had just filled up with gas the night before so I knew I was not out of gas. I turned off the stationary, stalled car and tried to start it again. Nothing! the engine died as I sat at a red light. I had it towed. There was no warning. One minute it was running fine and the next minute without warning signs, it was dead. A few minutes before I had been on a freeway with my car running fine. If it had happened then there could have serious circumstances.

I have been notified by Hyundai motor America that my car is part of NHTSA campaign 15V-568. The issue is metal debris from the manufacturing process causing premature wear and possible engine seizing. The dealer has informed me that the will evaluate the engine with a "sound" test, only, taking about 15 minutes. This being the authorized method from Hyundai to this dealer. I assume that NHTSA has approved this method of evaluation. This method of testing will only identify those engines that have already experienced enough excess wear to cause unusual noises. This dependent on miles driven which will vary significantly among the number of vehicles effected. Metal debris blocking oil passages will not be detected by this test. Crankshaft and bearing damage due to metal debris that will be a long term problem will not be detected by this noise test. Vehicles with low mileage such as mine may not have enough damage sustained to cause any detectable noises at this time. The proper evaluation of this potential problem would consist of removing of the oil pan and inspecting for debris, disassembly of the oil pump for inspection, removal of all connecting rod bearings and inspection for metal debris or premature wear. This process would provide a more reasonable assurance that a future engine seizure would not occur. This problem represents safety uncertainty unless properly evaluated, which I do not believe is being done per your approval to this manufacturer. If possible, I would like to have a copy of your written approval to this manufacturer to use the sound test for this important safety issue. I am available to discuss this matter at any time [xxx] thank you information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).?

Had a minor fender bender and the car stalled. I had the car towed and was told by Hyundai that the engine ceased. I was told it was my fault. I had the oil changed a few months before so I know that was not an issue. I was forced to either trade the dead car in of pay $6500. For a new engine. Hyundai told me over and over again that Hyundai had never seen this problem before. Then after 1 months and being forced to buy a new car I received a letter from Hyundai that my car was being recalled for the engine ceasing. I called Hyundai and they refused to do anything for me. This is the second complaint I have filed with you guys.

The engine oil pan was resealed five times and still its leaking. When they resealed the second time, they replaced the oil pan as well. After that it was resealed three more times and the car is at the dealer for sixth reseal. They are replacing the pan again. The brake caliper pistons are exhibiting excessive rust which I have not seen in my life while owning and maintaining various cars. The field engineer is saying that its normal and I don't agree with that. What I have seen based on that it's a design flaw. The caliper piston should be pressing completely against the brake pad surface area where as small portion of the caliper remains in non contact with the pad and the salt and slush during the winter gets into it making it rust which will impede the braking operation in future and may cause a fatal crash. Attached photographs are showing pack rust inside the piston on both the driver and passenger side.
