At random you will just be driving down the road and a message comes on that says reduce engine power and the T/C light comes on along with the check engine light. This has happened several times, is very unsafe, and is getting worse. We have had work done to try and fix the problem but its still happening. We don't have tons of money to fix this, live in the country, and have 5 kids. This is our only transportation and we have a rather large loan on the thing and its turning into yard art.

Driving down the road one day and reduced engine light comes on. My Suburban slows to about 35mph and will not go any faster. This occurs about 15 times a month. I am concerned about people driving behind me when it comes to a sudden slow if I can not get off the road. We have brought it to a dealership 3 times. They did not know what was wrong. We have changed the throttle pedal positioning sensor, map sensor, crank sensor, knock sensor, spark plugs, spark plug wires. Nothing has worked.

2004 Chevy Suburban w/80,000 mi. Used for towing rv-"reduced engine power". codes are not specific for the problem and multiple repairs have not fixed problem. This is an extreme hazard when towing as rig cannot move off the road with so little power. I am reading many posts online for the same issue.

I bought a new 2004 Chevrolet Suburban 1500 ls in early September 2005. One evening I went to a restaurant to eat, went inside and was seated. Maybe 5 minutes passed, could have been less. The owner began yelling that a vehicle in the lot was on fire. I looked out the window and saw what I thought was a car next to mine bellowing smoke. I ran outside to move my 2004 Suburban away from the burning car and to my amazement discovered it was my Suburban! there was absolutely no prior indication of anything wrong such as an over-heated engine. No indication of any malfunction whatsoever. The engine was completely off when this fire started.

The coolant level in the reservoir continued to drop, prompting me to refill it weekly. Service shop worked on this on and off for several months. After several engine overheating situations, we took it to a different shop. Turns out our heads are cracked. They were manufactured by castech and are known to be defective according to GM bulletin #06-06-01-019B (document id 1986750). There is now so much anti-freeze in our engine that the entire motor needs to be replaced due to the corrosive nature of the fluid. GM said that they would pay nothing towards our repair. The engine only has 91K miles and now needs total replacement B/C of an issue that GM knew about since 6/12/07 but never contacted us about. Had the replaced the heads back in 2007, we most certainly wouldn't be facing total motor replacement at this time.

My 2004 Chevy Suburban just dies while driving, I loose power steering & my brakes. It has happened 2X in 2 days. It presents a very dangerous situation, for myself & other drivers. When a diagnostic is run it is negative, nothing shows up. All of this out of nowhere.
