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 experienced a sudden loss of engine power while travelling at highway speed. I am the original owner of a 2004 chevrolet silverado 2500 four wheel drive with the duramax diesel and allison transmission. On sunday, october 4, 2015, shortly after a fuel stop, I was traveling on interstate 24 near paducah, ky. At approximately 65 MPH in the left lane with the cruise control set, I experienced a sudden loss of power accompanied by a loud engine rattling, and the check engine light came on. With some difficulty in heavy traffic, I was able to maneuver to the right shoulder of the road. I was able to drive the vehicle at about 25 MPH on the shoulder. Since I was just a few miles from the paducah exit, I limped there and into a hampton inn parking lot. Aaa responded and towed the truck to royal oaks chevrolet in paducah. Since it was a sunday, the service department was closed. The next morning, the dealership's service department pulled up codes po202 and p2149. The service manager reported that there was a service bulletin on this issue and that it would be several days before the repair parts would be available. I later learned that the service bulletin is #05-06-04-047c. The bulletin addresses "a severe reduction in engine power (limp home mode)" I was charged $1,076 for repairs for a known defect that chevrolet knew about.

Exhaust manifold bolts broke on both sides of engine, 6.0 liter engine, resulting in extreme noise, poor gas mileage, service engine light blinking and smell of exhaust entering cab. Why isn't this a recall item since so many people are having the same problem with chevy and gm trucks and SUV's? The cost of repair by a garage is astronomical and it's impossible to do it ourselves. The truck now has roughly 112,000 miles since we have to use it at times.

Four exhaust manifold bolts have broken off since I've owned this truck and the manifold has cracked. It is a design flaw that occurs in many of the similar v8 equipped models and has been well documented on the internet. This should be recalled by gm. This problem also leads to faulty emission readings by the vehicle and the check engine light will go on and remain on until this expensive problem is fixed.

This is how it started.. I have a 2004 chevy silverado 2500 hd. As I drove down the road the doors would lock and unlock on their own, and the truck would lose RPM's and would act as if the truck shut off and restarted itself. Also the check engine light would blink with the locking and unlocking of the doors. Did this off and on a few times as we babied it home. Got it home in the driveway and it threw 2 codes camshaft position sensor high volts and low volts. So we replaced the camshaft position sensor. Truck drove fine for 4 days. However on the 5th day we attempted to drive the truck and as we were driving down the road this time the engine light came on and stayed on and doors started locking and unlocking again on their own as well as the dic read service brake system and the truck completely died in the middle of traffic, we were able to pull over into a parking lot and truck restarted long enough to get home. At this point the gm dealer wasn't sure of this problem and what causes it but stated to unplug the battery and reset the computer(after speaking to 4 different gm dealers mind you). Wow low and behold fixed the problem for about 45 minutes, as we again tried to see how far we could make it before it started acting up again. Only this time doors would lock and unlock and all kinds of weird things were going on, for example doors locking and unlocking, truck stalling and restarting, idol was ruff and noisy, service engine light came on and stayed on, and the dic read this time reduced engine power!! And at this point we were only able to go 15 miles an hour and thankfully we were on a road with no traffic and were about 2 miles from our home. Also in the mist of all of this the truck was chiming and the truck thought it didn't have any brakes at this point thankfully we were able to get the truck to come to a complete stop. We have had this truck for less than 1 yr and it only has 82,000 on it and noone seems to be able to tell us what is wrong with it.

At 35000 miles the check engine light came on and the dealer replaced parts with the gas tank/fuel line due to it being 'plugged'. 10,000 miles later it happens again but no warranty and after very dissatisfying service at dealer we opted to a new mechanic. He reset the check engine light but 1 week later it was on again. Then he replaced the emissions line and 3 days later the check engine light is on again. One dealer stated that excessive driving on gravel roads leads to this problem that the fuel system is not vented properly. (??) we are ranchers and the majority of our travel takes us on gravel roads. Hopefully someone figures this one out so it can be fixed....
