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 contact owns a 2001 Hyundai Sonata. While driving at an unknown speed, the vehicle stalled without warning. The crankshaft sensor failed and was repaired at the contact's expense. The failure recurred two additional times due to the crankshaft and was repaired under warranty. The dealer stated that they would only pay for the part, not the labor. The vehicle has been at the dealer for approximately one week, but has not been repaired. The VIN was unknown. The failure mileage was 130,000 and the current mileage was unknown.

: the contact stated without warning the vehicle stalled, on five occasions. This happened while driving at no particular speed. The vehicle had to be pulled over and towed to the dealership. The final time, the dealership determined there was a rotor in the crankshaft sensor that was dented. The crankshaft sensor was replaced. Also, a puddle was noticed under the vehicle. The dealership determined there was a rupture in the power steering line and the line was replaced.

I was driving along and the engine shut off suddenly. Crank shaft sensor failed three separate times in this vehicle. Once at 32,000 miles. Nearly lost control around a 90 degree bend. Second time occurred June 9th, 2005 at 83,000 miles after turning off a highway. Third time it occurred was July 15th, 2005. I was idling and attempted to put it in drive to proceed forward. I had it towed twice in three days to dealer. Each time, the sensor was replaced. The last two times the crank blade was also replaced. None of the times did I expect there to be any problems with driving the vehicle. Now I am worried a lot. The second time, I could tell it was happening since the RPM needle dropped to zero and then it shut off.

Engine misses and backfires through the intake. The major problem is when the engine is running and it doesn't matter if it is in park, or if you are driving it. I was on my way to work when it malfunctioned. I was sitting at a signal light when the engine accelerator went up to 4200 RPM by itself with no foot on the pedal. I almost got into an accident, I pressed harder on the brake pedal and had to take it out of drive to avoid hitting the car in front of me. The engines rpms change a lot now and will not idle right at all; this car is not safe to drive with these engine problems; and should not be on the highway. I had a Pennsylvania certified inspection mechanic look at and drive the car; and he said the car is not safe to drive; and if it would have been due for state inspection that it would have not passed; but failed and would be illegal to drive.

The main pulley came disconnected and fell off onto the street with no waring whatsoever. Luckily I was preparing to turn left and was stopped in the left turn lane. There was a bad thunk and shake and the car shut down. Had I been moving, it could have been a very different story, especially at highway speed. It is a brand new car, I just had the oil changed. Everything was fine, I thought. I was told that this was a serious problem that should be reported to you.
