Check engine light came on and "low engine power" flashed where the odometer is. This caused the RPM's not to go over 2800. Code reader claims o2 sensors or throttle control module or catalytic convertor issues. We discovered it was none of the above. To fix problem change 3 relays located under hood in fuse box. Relay #8864. Then clear codes, should fix issue unless code persists. Relays will cause a fire if not changed out asap.

I have had a complete brake job because all of the lines rusted out and failed as I was driving. Fortunately, I was able to use the emergency brake to stop safely. I spent rough.y $3,000 to get this repaired. Now the fuel lines, fuel cooler and everything attached has rusted out to the point that it is going to be an additiona $2,500 to repair this. Also, the complete under carriage and rear end has rusted to the point that I am expecting it to fail at any time. This is not only a dangerous situation, but is extremely costly to the consumer, me. When the brakes failed, I was driving on a street approaching a busy intersection. With no warning at all, the pedal went to the floor and I had no brakes. The repair facility mechanic said he has never seen a system so bad. I keep the vehicle in a garage and have washed the under carriage in the winter to keep road salt from accumulating.

While driving in heavy denver, colorado traffic late afternoon hours of 07/18/2014, my 2004 chevrolet silverado 2500 hd, duramax lly had a "significant reduction of engine power". Gm was aware of this as early as august 17, 2009, as per their bulletin # 09-06-04-034. This bulletin states this may be caused by the fuel injector wire harness rubbing against the bracket and chafing the wire insulation. This occurred on my vehicle causing one wire to short against the bracket. This immediately shut down the affected cylinder bank resulting in an immediate reduction of engine power. I feel this could be a safety concern. Fortunately I was able to get to the side of the roadway without incident. I have sent three emails to [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

I had my fuel injectors replaced in june of 2010 under an extended warranty from gm with no out of pocket cost. 18 months later I am having the same problem, fuel injector failure as diagnosed by a local chevrolet dealer, but being told that I am now out of warranty and it will cost $3500+ to repair. If there is a defect in the injectors, previously covered for 7 years/200,000 miles, why are the "new improved" injectors only coming with 12 months/12,000 miles. Gm has a fuel injector problem with their duramax diesels that need to be addressed. I have read hundreds of post from people with the same problems. And chevrolet is not offering any help with any of them. I am dealing with gm now, and so far have gotten nowhere with the issue.
