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.

Silverado 2500

  • 160,000 miles


The contact owns a 2007 Chevrolet Silverado 2500. The contact discovered that the egr cooler sensor failed and became inoperable. As a result, the exhaust pipe overheated. While driving at an unknown speed, the diesel filter sensor increased excessively to 1,500 degrees. The vehicle was taken to a dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 160,000.

Upon driving the engine began making extreme noise and major loss of power. Multiple engine lights came on and backfire through exhaust. Contacted Chevy dealer and dropped off for diagnosis. Problem was active fuel management lifter failure. (please take note that this issue is all over the internet and social media) this problem is happening to a high volume of Silverado truck manufactured after 2007 with afm. Chevrolet has bulletins on the issue but will not recall to replace all afm lifters. They only replace the lifters that fail. This causes issues later when additional lifters fail. If all aafm lifters (8) would be replaced at the same time consumers wouldn't be complaining via social media and internet. Chevrolet acknowledges the problem but refuses to recall. Reason for refusal is it seems to happen around 50,000 miles and above and after the repair they hope that the issue happens after the 100,000 mile warranty when repairs are paid for by consumers costing thousands of dollars. I personally have read of this happening and had it happen just recently. GM refuses to back their product although they recognize the problem. Bulletins have been issued but I was told that the NHTSA makes the call after enough complaints are filed by consumers. People just don't know this and I am requesting you urgently look into this issue. Catastrophic engine failure can result costing consumers a lot of money. We are just the little guy up against a large automobile manufacturer. We need your assistance in forcing GM to issue a recall on these vehicles with the active fuel management. Our hands are tied because of this. We request that if there is a afm lifter failure that all lifters be replaced instead of the ones that failed. This is only logical especially when GM knows there is a problem. Please help us the consumer.

Silverado 2500 8-cyl

  • 24,308 miles
On Dec. 23, 2011, I took my Silverado into joe firment for an exhaust leak (which is an emissions problem), so I wanted it fixed immediately. They found nothing. On May 22, 2012 I took my Silverado back to joe firment for the 3rd time for this same issue - exhaust leak. At that time they had found one broken bolt on the exhaust manifold (actually there were two broken bolts that I found personally upon further inspection). My warranty covered the manifold but had just expired on May 7, 2012. I asked that they honor my warranty since the problem has been there since 2011, but they failed to diagnose it. Joe firment refused to honor my warranty. I researched this issue online and found that several other people have had this same issue with their GM product. This should be investigated as a possible class action suit. How many similar complaints are on record? this being an emissions issue will cause my vehicle to fail the emissions test required to renew my license plates. This needs to be corrected and should be covered under my original warranty since the problem began within the warranty period. The dealership should have diagnosed it on the first appointment for this issue.

Exhaust manifold bolts broken on 6.0 liter engine, 2 on passenger side, 1 on driver side, causing exhaust leaks and service engine light. Possible fire hazard as exhaust gases entering underhood environment, and definite emission problems as O2 sensors incorrectly sensing diluted exhaust after leak in system, possible fuel mileage affected..

Silverado 2500

  • 1,000 miles
I took my new Chevy truck into the dealer for some new factory equipment (bug deflector and bed liner) to be installed by them. While the dealer had my 2007 Chevy truck they loaded 2008 power train software into it's computer without my permission. The 2008 software changed the way my truck runs. The power train now has a speed limiter on it and the stability control was changed. It will not go as fast it as use to go before the change. I was told by the dealer and GM they would not put my truck back the way it was as when I bought it. They told me that the reason was the Goodyear tires and the truck design were unsafe without the 2008 software installed and would not change my truck back to the 2007 configration. I have not gotten any recall or safety notices about this issue. I think GM and the dealer made a mistake and do not want to correct it. If there is a problem with the tires (Goodyear Wrangler tires) and the 2007 truck design (GM Silverado 1500 lts crew cab) GM is trying to cover it up. There are hundreds of thousands of 2007 GM trucks, cars, SUV's even Cadillac's that have the same power train in them that my truck has and they are not changing the computer programs in all those vehicles. I was told they would be changed only if the trucks, SUV's and cars were brought in for any kind of service work, but would not be changed if not serviced by GM. Sense there have been no recall notices about these issues I think GM is trying to cover something up. The very least trying to cover up their dealers and there mistake by altering my truck without my permission or they do have a serious problem that the public should be aware of. Please look into this. The same tires are on Ford and Dodge and they don't software limit there performance. I paid top dollar for GM's best truck with the biggest engine made for it, I could have saved a lot of money by buying a six cylinder engine instead of the big V-8. if I knew GM was going to de-rate mine.

Silverado 2500 4WD 8-cyl Diesel

  • Automatic transmission
  • 16,000 miles
The contact owns a 2007 Chevrolet Silverado 2500. While driving in inclement weather conditions, water entered the air filter and caused the vehicle to decelerate to approximately 5 mph. The contact heard a loud rattling noise and the engine light illuminated on the instrument control panel. The vehicle stalled and then automatically restarted five minutes later. He took the vehicle to the dealer and they stated that they would have to modify the entire intake system by removing the sensor from the filter to the engine. The service manager stated that he did not believe the modification would resolve the failure, but was obligated by the manufacturer to perform the repair. The vehicle is currently being repaired. The failure and current mileages were 16,000.
