1 Engine Oil Leaking problem

Failure Date: 03/01/2019

The airbag light ha been on in my car for about 3-4 weeks and stays on continuously, will not go out. I have tried to have it reset, but it does not help. I believe this is or should be a recall because I have been reading over the internet and several other owners of this make and year model of Hyundai are also having these same issues. Also, there appears to be oil leakage but we cannot see it. We have to add oil to the car every week, even after we have had an oil change the week prior. I took it to Hyundai of bowie with these same issues several months ago, but they said there was no recall and before they could check it out, there would be a bill. I did not have the money and believe there is something wrong with the engine and may be part of the recall.

2 Engine Oil Leaking problem

Failure Date: 08/31/2018

I pulled out into traffic on a city street and my car revved up between 4 and 5, and than all lights on dash lit up and my car died. I coasted into parking lot (safely thankfully) and car started smoking so got out immediately. My car was towed to local repair shop who replaced starter which was what they believed it to be. Turns out it was not starter it is engine that will need to be replaced. I looked into recalls and contacted Hyundai customer service who informed me this engine recall had been completed already. I was directed to dealership to follow up on what options there are as 'extended warranty' only covers up to 120000 miles which my car is over. The repair shop I went to mentioned there was no oil on dipstick when checked which is concerning to me as that seems to be what result of recall that was completed would result in, along with other symptoms like dash lighting up which I read from other reports. I am always up to date on getting regular oil changes at 5000 miles they now recommend instead of 3000 miles (which dealership records will show), and was not at 5000 mile point so that should not have been an issue. I also do not recall being informed of any oil leaks or concerns for this vehicle that I would have needed to keep an eye on. I have yet to follow up with dealership as it is holiday weekend so will see what they are able to do. I want to know who to contact if a recall does not fix the problem and what next steps are to help me as a consumer who always takes care of car. A cars engine should not be bad at under 130000 miles and too many similar symptoms to not have it followed up on and manufacturer take some responsibility. I am going to have to have repair shop fix it and get reimbursed unless Hyundai dealer is willing to have it towed so they be responsible and strive to provide honest customer service and stand behind their car.

3 Engine Oil Leaking problem

Failure Date: 07/22/2016

Oil feeder line leaked. This was a known defect in the 2011 vehicles. Occurred just out of warranty period. Hyundai would not replace under warranty even though this is a known issue with the 2012 models as well.

4 Engine Oil Leaking problem

Failure Date: 01/30/2016

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.

5 Engine Oil Leaking problem

Failure Date: 11/09/2015

Oil pan has been leaking and resealed four times. After first two times the dealer replaced the pan and resealed it again. It started seeping again and I am sick of it. The oil pan has been leaking since the car had only 7000 miles on it and I bought it brand new.

6 Engine Oil Leaking problem

Failure Date: 08/10/2013

First time noticed that the oil pan is leaking at 15,042 miles. Took the car to the dealership and they resealed it under warranty. Started leaking again at 22,566 miles and took it to the dealership. This time they replaced the oil pan and resealed it again under the warranty. I just noticed it that it's leaking again at 30,660 miles. I am really concerned that this brand new car is leaking oil like this. Also, I strongly feel that the fix is not addressing the underlying issue which may be something else. I think Hyundai needs to look at this issue closely and must come up with a permanent solid fix. I have been reading on the Hyundai Sonata forum that many are facing the same problem. I am surprise that there is no recall for this yet. This is my first and last Hyundai.
