2011 Hyundai Sonata Owner Comments

problem #3

  • 135,000 miles


The contact owned a 2011 Hyundai Sonata. While driving highway speeds, an abnormal noise could be heard from the front end of the vehicle. The contact also stated that the door latches failed, which allowed the doors to remain open even when the vehicle was in drive. The vehicle was taken to an independent mechanic who diagnosed that the door latches and the front coil springs were defective and needed to be replaced. The manufacturer was notified of the failure and the contact was informed that they could not be of any assistance due to the VIN not being included in NHTSA campaign numbers: 10V070000(latches/locks/linkages) and 15V629000 (suspension). The contact was informed that NHTSA had issued out the recalls and they were regulated by the manufacturer. The approximate failure mileage was 135,000.

2011 Hyundai Sonata: I had heard about the door latch recall on my new Sonata via news reports. I purchased this Sonata on Feb 16th,2010. So, I called and the dealer(St.augustine Hyundai)said I wasn't included in the door latch recall. The dealer said there was 2 bulletins on my Sonata anyhow. #1, the ignition wire needs rerouting or it could become afraid. #2, the ECM computer needed re-programming at that time with an explanation that some new software from Hyundai when it arrived to the dealer, they would check the parameters of the ECM computer program. Now, I haven't to this date received any information regarding any of these 3 issues with my new 2011 Sonata from anyone in the mail" on 3/16/2010 yesterday I received a call from Hyundai usa corporation. The man said my car" is" affected now by the door latch recall. I didn't ask him about the other 2 bulletins mentioned by the dealer nor did he mention them to me. He said I would receive a letter about the door latch recall soon. But nothing again about the other 2 issues" I have been on hold for 45 mins once today and 35 mins yesterday and just hung up because its been too difficult getting anyone at Hyundai, the press(or speak) recall option to route ones call on phone or dept said its having high call volume due to recent recalls.I called St.augustine Hyundai back yesterday and spoke to service manager and he said it's showing now about the door latch and the other 2 issues still exist like he told be weeks back already on the phone. I asked what needs reprogrammed with the ECM computer. He asked me to hold, came back and said if that isn't tended too. The engine could stall or the car might suddenly be able to go no faster then 20mph. This sounds unsafe and I haven't received any letter official from Hyundai corporation. If I'm driving and my car stalls or I'm on the freeway and the car drops from 70mph to 20mph without my desire to do so is unsafe?they supposedly spent 4 years developing the vehicle.
