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.

The system warning lamps illuminated, then the engine shut off and would not restart. Evaluation showed that the alternator had failed and was covered with engine oil which had leaked from the front valve cover gasket onto the alternator. This failure is the same as NHTSA campaign number 14V415000, which covers another Hyundai vehicle.

Under normal driving, vehicle suddenly sputtered a bit and then the check engine light and electronic stability control light came on. The car then would barely move over 15-20 mph. We found out that these are the classic symptoms of a tps issue, for which Hyundai issued tsb 10-fl-010. We have had the vehicle at the dealership for all of the recommended repairs from that tsb twice with no resolution to the problem. My concern is that this problem occurs randomly and without warning. At least twice it has occurred on the interstate, and I felt we were lucky to get off to the side without another car running into us. I am extremely worried that the next time this happens we won't be as fortunate, and someone can be seriously hurt. This is also a very common issue with Hyundai. Frankly, I would not be surprised if someone has already been hurt because of this. I am also surprised Hyundai has not issued a recall or found a better solution to this problem. I believe this is a very serious problem and urgent safety issue. In fact, we would like to get rid of the car, but we cannot afford to buy another car, nor am I too keen on inflicting this problem on some other unsuspecting person thinking they are buying a good, reliable car. Please try to pressure Hyundai to come up with a better solution.

My 2006 Hyundai Sonata has the check engine and ESC lights come on, then the car wont accelerate as well as the rpms will not move. The car coasts like its in neutral. And today was the last straw when it decided to do it while going down the road instead of just when beginning the drive.

Oil pan rusting out. A lot of engine motor oil seeping out of entire oil pan. Professional mechanic states this is not normal wear and tear at this low mileage. Eventually oil will leak out causing engine to seize and fail.

Sonata 6-cyl

  • 70,000 miles
This vehicle was taken to the authorized service center of Hyundai on October 29,2013 for the safety recalls received from Hyundai motor America (NHTSA campaign number 13V-354 and failure of OCS recall by NHTSA).since the service personnel insisted to do 70,000 mile service I agreed and after 1 hour he called me and said there is a leak in the radiator hose. This car has always been serviced by authorized Hyundai service centers and always had persistent problems like oil leaks (changed gaskets (paid$400), power steering leaks (paid $300), brake rotors problems which I had to pay $1300 to replace at 30,000 miles etc etc.this car comes with 10 year/100,000 bumper to bumper warranty that is fake.I had also paid ($1200) for an extended coverage for this vehicle when I bought this brand new. But Hyundai did not honor it since it was a dealer package and that dealer no more exist. On October 29,2013 after the recall service I paid $400 since the service manager said he did all that is urgent for this car. Next day morning I found my car in a pool of multiple fluids.I decided to take it back to the Hyundai dealer, but on the way the car was engulfed in smoke. I pulled over to the gas station which had a work shop, found that no coolant in the car. They filled the coolant and put a new clamp on the hose which was loose. I made a complaint to the Hyundai motor America after 2 days. Case number is 6156086. Since then I escalated the case calling them several times, but no reasonable effort from there side to help me. On November 13, the car again burned and got engulfed in huge smoke when my wife was parking in the drive way after returning from work. (I have the video on my cell phone). Again I called Hyundai America and they told me to contact the dealer. I called the dealer (Hyundai of paramus) and they said the service manager will call back. But never did.
