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 throttle body and pedal chip went bad causing a rough running engine, loss of power, check engine light, and loss of traction control. Mechanic stated he's been replacing 5-12 a month on the same engine (5.3 liter V8). Other models are supposedly under recall. Repairs cost in excess of $500.

Pulling out of a snow covered parking lot the engine light came on dic then the message, reduced engine power, the engine began to run very rough at a lower idle speed, as began to happen the truck lurched forward and I had to press hard on the brakes very hard like I was fighting the engine speed to slow, then the message changed to service traction control, I had no control over the gas pedal and could only move at about 5mph, then the message changed to service stabilitrak, I got to another area of the parking lot, parked and shut off the engine for a few minutes and the issue would not go away. I was more than two hours from my home. I removed the red battery cable then replaced it and was able to start the engine and it operated normally for a while. One and a half hours later while driving 60mph it happened again and I cost off the interstate and could not get it running again. Had to be towed to a dealership. They said there was a service bulletin to replace the throttle body but want to charge me $215 to clean the other fuel related parts. This needs to be a recall. If it was a recall I would not have to pay $215 to complete the work properly.

Noticed one morning when starting up my truck the valves were tapping. Like out of adjustment. My 5.3 is roller lifters so I was surprised. Took it to dealer and was told that GM had a recall on Cadillac, Chevy and GMC 5.3 and 6.2 engines with defective lifters. Dealer replaced the lifters. Took a week. When I picked up truck service adviser told me to expect to come back around 60K for a new camshaft. Now what!
