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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #4

XG350 6-cyl

  • 2,500 miles

A D V E R T I S E M E N T S

Seven instances of unwanted engine acceleration since Jan 2006. All occurrences similar: 1)engine is warm after a period of driving; 2) car decelerating approaching stop sign, traffic light, or in stop-and-go traffic; 3) a barely audible "click" is heard and the engine RPM begins to rev up making braking difficult and giving a clue that something is amiss. When this point is reached key was turned off or idle selected to see how high the RPM would rev; 4800 is the highest noted. This is a random event as the car has over 10000 miles with 7 occurrences. Latest date is noted below.

  • Automatic transmission
  • 2,431 miles
Initially (2) times there was no response from engine when gas pedal depressed, we have had 3-4 incidents of when stopped at intersection, or driving slowly in parking lot engine surges and breaks had to be applied severely to prevent car from hitting other cars, the last incident was the transmission would not shift from 1st gear and car would not go faster than 20 mph. All of these are safety issues.

problem #1

  • miles
2005 Hyundai xg350L intermittently stalls when put in motion, then rapidly accelerates and surges forward. After a few seconds the vehicle will regain power and surge/lunge forward. The vehicle was taken to the dealer but they were unable to duplicate the problem. They replaced the throttle body but that did not rectify the problem.
