I took my 2003 Chevy Tahoe into the dealership because of performance and gas issues and was told I had 2 broken exhaust manifold bolts. The repair was estimated to over $1000. I know that this is a major issue with GMC and Chevy engines with many complaints. The manufacturer should stand by their product and fix this issue instead of making their customers pay for a defect that exists with their product. I was told that my vehicle would not pass safety inspection without this fix.
Exhaust manifold bolts breaking leaving studs in the heads, heating up engine compartments, releases carbon monoxide, affects O2 sensor and catalytic converter. Will not pass emissions in some states. GM not standing behind this 1999-2008 issue. It is a safety issue and is expensive to fix. GM mechanics denying any such issues. Please check- in to this. Our whole fleet and our personal trucks affected by this.
The reduced engine power light came on and reduced the car's power to only be able to go 20 mph. I did reach 30 mph with a down-slope. I was very scared and had my two children in the car. Thankfully, I was able to safely pull over to the side of the road. Upon researching this issue with my car make and model, it seems to be a common problem and a very serious issue. The engine's power just pulled back without warning! I am taking the car to be serviced tomorrow but cannot fathom to think what could have happened!

Bought vehicle in February of 2009 used after driving truck for about 10 days we realized that the speedometer was not moving when the vehicle was in motion. Then after that the speedometer would move up in speed after driving the car for about 20 minutes but then stay at the 30mph when stopped once the car would begin moving again the speed would continue to go up from the 30mph mark resulting in the speedometer reading 60mph when the vehicle was actually only going 30mph. This has continued every day since it was noticed so when driving the car you never know how fast the car is actually traveling.
Engine knocks when it started after sitting for a while untill oil pump picks up.I personally know of five other 5.3 liter V8S that have the same problem, but my dealership has never heard of this.I find this hard to believe. A friend told me that there was a tsb reguarding a check valve of some kind that would stop this.
"reduced engine power" message displayed 3 times within 4100 miles of brand new Tahoe. On 4th visit, dealer replaced throttle body with a new one at 4366 miles.
We have a 2003 Tahoe with a 5.3L V8. There is a hissing noise and a vibrating in the engine after running for about 15 minutes. The dealership can't fix it and doesn't know what is wrong with it. They think it has to do with the A/C but they replaced compressor and belt and it still makes the noise.
