Car will not start when I hit the start button. Sometimes it will and sometimes it takes 4 or 5 times to start. Car makes an electrical rattle like noise but doesn't turn over. Also, when I try to shut the car off, my display will tell me to shift to park and the radio will stay on. I've had the car in for the shift lever cable recall but I believe there is more to this. The car is doing the same thing before and after the recall fix. I commute 200 miles to work so the miles I post will be high.

My steering wheel has become increasingly loose and shaky over the past months when driving or stationary. There is a very distinct (and getting worse over time) "clicking" or "knocking" sound when I back up and turn my wheel either way. I was told by my mechanic that something is wrong with my steering gear box/shaft sector and possibly some of my axles. He told me this was dangerous, and that the recall campaign number 097 should cover me. However, I was told by Hyundai that my specific car does not fall under this recall, even though I my car has the exact symptoms of the recall. I was also told that because of recent recalls, my warranty would be extended. However, Hyundai has now told me that my warranty extension only covers the sole engine, and not the axles though they are part of and covered by the initial engine warranty. Hyundai has told me there are "kits" to fix these problems, but I have to pay over $1000 for the kits to fix, even though these were faulty parts by Hyundai. The Hyundai service manager I spoke with told me flat out that my car had faulty parts, but that the kits could fix them. I asked him whose fault it was that they were faulty, and he said that all car companies deal with this and it wasn't because of my driving. But even still so, I have to be the one to pay for Hyundai's faulty parts and non-existent recall help. I'm beyond frustrated after reading so many reviews and forums online of people with the exact same car symptoms as mine who are unfortunately also not covered by the recall. If I cannot get a better response and answer from this, I will be contacting the main lawyer who others have also contacted about this and filing an official lawsuit. I expected way better from Hyundai and am disgusted and disappointed at the lack of service, truthfulness, and integrity from this company at this point.

Weeks after I got the new car from the dealer the car commenced to make the weird noise related to NHTSA campaign number: 15V568000. But also was some heavy burned oil smell coming from the engine. After the authorize dealer make me pay over $700 to fix some broken parts (cover of oil). After few online researches I understand the debris cause the broken parts of my oil engine. And I need to confirm what other risk and consequences are involved.

First, this is my 2nd complaint I've filed. My car has been repaired many times for recalls (one is being done currently for the second time) and other warranty repairs. This is the list so far: Idler pully, tensioner arm and belt, steering column (which broke while driving after I had to get 4 new tires and 4-wheel alignment (24000 miles) that they said I had to get), premature starter failure, short block, leather around gear shifter wore hole in it, and my car has now been in the service dept. Since Dec. 17th because the engine failed again. They ordered a long block for it but Hyundai motors America cannot keep up with getting the engines manufactured and sent to all the dealerships fast enough for the recall.I am now the 12th car down on the list. I still have another outstanding recall for the brake stop pad, and I noticed recently the rearview mirror is faded in spots (dark worn areas). I contacted Hyundai motor America public relations hotline. It took them 2 weeks to get back to me. The man that called me asked for information from me, he called the dealership, and then sent me a letter stating they would only reimburse me a portion of my repairs I had to pay for. In the letter, also was a release of liability for me to sign. That's not going to happen!!!! the release would have made them not liable to past or any future situations, including death. How stupid do they really think we are? they've had well beyond an acceptable amount of time to take care of these recalls. It's time to buy the vehicles back and rebuild their image. If not, there will be more recalls or events that could lead to death. Holding them accountable is the only acceptable way to handle this.people are still out there driving unsafe vehicles!!

I have complied with Hyundai in regards to the two recalls on the vehicle. Although, my vehicle has sat at the dealership since November 5th 2015. The dealership has yet to receive a new engine from the manufacturer. Furthermore, I still pay payments on the vehicle and have done so before the recall was released as well as even after it was sent to the dealer, as requested by Hyundai. I spoke to Hyundai today as to an update to when this will be completed and they did not have an answer. I sent them a letter requesting that they buy back the vehicle do to the safety concerns as well as the delay in fixing this matter. They declined and this is why I am filing a complaint. They have not or have they ever taken accountability for these issues from my standpoint and the car has lost substantial value due to these ongoing recalls. I am paying on a vehicle that is no longer worth the payments. I have requested a buy back due to the quality of the product Hyundai made. They falsified their commercials and hyped up the quality of their product and no longer are they standing behind it.
