While driving multiple indicator lights on the dash came on, (brake, ABS, tractions control, steering, seat belt, air bag and check engine lights.) T highway speed the transmission shifted into 1st gear and I was forced to exit the road immediately. I safely came to a stop and shut the vehicle off. I then restarted it and then I was able to safely get home. I then called aaa and had the car towed to my mechanic. My mechanic found that they could not communicate with most modules/computers that are in the car. After hours of testing, they discovered that the back up camera was corrupting the computer data lines and essentially shutting down crucial modules in the vehicle. Once the camera was removed from the car, the vehicle operations returned to normal. Please advise Hyundai of this issue, so other motorists can be spared this frightening experience. I will provide the invoice for repair and the failed part, which I have in my possession, if you need. Please contact me for further information.

On three occasions my car would not start. After the second time it failed, I brought it in. Hyundai service department could not find anything wrong with it after hooking it up to the machine. No codes showed on the system check. They said they checked the battery. They said it could be the brake sensor, which was changed from a recall, so they said I have a new one, they would just adjust it and hopefully would fix the problem. Three days later on a Saturday morning, the car would not start again. I brought it back in. They kept my car from 06/20 - 06/30 and could not find or reproduce the same problem.

Went to start the car all it did was go click. Tried different key fob, it started, replace both batteries in key fobs. Next week, wouldn't start, let it set for a bit, it started, week later on a Saturday tried would not start, called Hyundai 24 hr road service, they had trouble starting it. Next morning it started, 6 hrs later it wouldn't start, moved the shift lever from park to drive back to park like the road service guy did, it started. It started the next morning Monday 6/22/15 took it to the dealer, said they couldn't find anything wrong, even though the battery shows a charge of 10 volts. I have a print out from pep boys showing that the battery needs replaced soon as it may not start a car. Which they were right. Hyundai Corp. Could care less about me or my car, what I think, they sold a car is all they care about. Between me and my two sons we have purchased over the years 8 Hyundai vehicles. Because what they are doing, or should I say not doing for me there dad, no more Hyundai cars, Hyundai does not stand by there cars, warrany their products. I'm asking if they will buy the car back, guess what no word from them, ms tiger the rep was to call me never herd a word from her. More of their we don't care about the owners of Hyundai Sonata cars.

I noticed that my blinkers were working but I could not hear them and my seat belt did the same. I went to the morgan Hyundai dealership. They found that the vehicle was not making chime sounds caused by insufficient volume coming from chime in BCM.they ordered the module to correct and replaced it a few days later. When I left the dealership I could not tell any difference in the chime sound. So I thought it might be my hearing and scheduled an apointment with and ear doctor. I explained to him what was happening. He tested me and said that I did have some difficulty in hearing high pitch sounds but that it was not bad enough to have hearing aids. He went out to my car and listened to the car chime and said that he had good hearing for his age and he was also having diffficulty hearing it. So I left his office and went back to the dealership. I was met by a very young lady and she said that she could hear it but it was not very loud. She then got an elderly man that worked there to listed and he had the same problem as I did. Then we got a middle age woman sales person to listen and she had difficulty also. Then they got the keys for four 2014 Sonatas and tried them all of them failed the test. So as a last resort we got the keys on a 2015 Sonata and we could hear it fine. They said that they would contact Hyundai to see if this is something that will be recalled or if they have had any other complaints. It concerns me because I am use to hearing the chime when I put my keys in my car and if fixed may cause me from having an accident with out my seat belt on. Please let me know if yall are having this problem anywhere else. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Car battery goes dead, unable to start car, could happen at any time. This has happened 3 times. The dealer has no idea why. Even Hyundai Corp does not have any answers. The car has been back to the dealer for days at a time with no resolution. I feel this is a safety concern because the car can leave you stranded, it is so unreliable. This is a 2014 Sonata. I see many problems on the internet for this problem with Hyundai cars. It appears to be associated with cars with "push to start".
