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.

The contact stated the check engine light came and the engine started missing. The air reflector on the bottom of the throttle bottle plate disintegrated; the air reflector has gone through the motor. The plate was embedded in the pistons, broke two spark plugs, and bent push rods. He changed the spark plugs. He then pulled the vehicle in and realized the push rods and lifters were bad. He contacted the dealer they offered no free remedy.

The consumer owns two GMC vehicles with the same problem. The consumer received nets recall 05V155000 on one of the vehicles but not for the other. The problem was with the fuel module reservoir assembly. Since the VIN was not included they would not correct the problem. (12/02/05) the service engine light soon stayed on and the fuel gauge did not work properly.

I have reviewed other owners complaints regarding their front suspension, fuel pump with random shut offs. My vehicle is experiencing the same and similar problems. As of today my vehicle is in the shop;I was doing 35-40 mph when vehicle just un expectedly shut off. I was stranded on a major road which cause a significant traffic delay. I have an oil leak from the hose leading to my oil filter and the vehicle pull to the right sharply if I release the steering wheel. The vehicle makes a popping sound when turning. These problems are hard to find just an isolated incident when so many consumers are having the same problems.

Lost complete oil pressure. The oil cooler lines are placed directly on the steering gear box, and the vibration caused the lines to rupture, which resulted in all the oil draining out.

While driving engine check light would come on and remain. Prior to engine check light coming on, vehicle would run rough/ would jerk, and hesitate. Problem is intermittent. Been to dealer for repairs, and air pump solenoid was replaced.
