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.

This is my second complaint about my fuel pump. Which was replaced last year. Again on 8/2/16 I was driving on the highway 495 South toward richmond va. I was driving 60mph. When my car shut down. I was almost rear ended trying to move on the side of the road. I had my car towed to the pohanika hyunda dealership in capitol heights, md. The same place I had my fuel pump replaced last year. I was told it was the same problem and it happen to another car. I suspect it was a defective fuel pump. After I complain, the dealership states they will replace the part and not charge me, but I would have to pay $375 for the labor. I complain to management and they say they would pay for half the labor. The reason I'm writing this letter, because if there is a defective part, I don't want someone to be hurt or kill behind the wheel, because of a defective part. I had file a complaint with your Agency last year with no response. I also contact Hyundai costumer service and the better business bureau.

Whenever filling gas, I would use a automatic cut-off in fuel dispenser lock. But the lock is always released after the point of release allowing gas to overfill and would cause gas to spread on side of vehicle as well as on the floor. This has happened regardless of the gas station pump.

When I pump gas even when on a empty tank, the gas will splash back all over the place almost like its full but when it's really empty, also the ESC will turn off and on by its self from time to time, had too replace the fuel pump at 90,000 miles, now I'm getting a code PO449 even with new gas cap.. last but not least my paint is peeling off my car, especially the hood and roof. Noticed Hyundai sheds there paint,

I was traveling on the beltway doing 65 mph, I pressed on the gas pedal. I felt I was losing speed. I notice the speedometer decelerating down to 40mph while I was pressing the gas pedal. I put on my hazard lights pulled to the side of the road. I was concerned because no warning light came on, to notified me there was a problem with the vehicle. I took my car to the dealership, it was diagnosis as problem with my fuel pump. I check with Hyundai they said, the fuel pump does not have a warning light. My concern if some type of warning light should have appeared on the dashboard before I started the car. I would have not drove the car if the warning light was on, I would have took it to the dealership. I felt this was a safety issue because someone could have rear end me on the beltway, due to the sudden drop in speed. I have enjoyed my car so far, but I was disappointed regarding this incident. I have a son who drives my car, I am worried about his safety and the safety of others. I was assigned a case number with Hyundai 8216379. However, I spoke with a case manager [xxx] who said it was not much they could do. I wanted to have a record on file regarding this compliant, and to see if it could be investigated.
