Bought this vehicle a few days before the first incident. I drove it home from over two hours away, drove it all around the day before, no problems. Then I was driving down a bypass at about 60 miles an hour and the engine shut off! I had no power steering, nothing! I was able to pull over, shut it off and once I turned it back over it was just fine. So I cautiously started driving, it happened again a few miles down the road only this time it stalled then regained power and quickly shut off again. Once engine was turned off and restarted, it was fine, it did this to me 5 times within 5 miles. I almost got hit two of those times by other vehicles, once when I was turning onto a road. I am glad my kids were not in it. I am scared to drive on two lane roads without room to pull over.

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.

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.

I have a 2004 chevy suburban 1500 with 90k miles. In november 2008 at 80k miles I noticed the heater wasn't heating. Checked af to find it was a gal low. No leaks detected anywhere and no smoking from exhaust. A few weeks later the same thing happened. After taking the vehicle to 3 garages including one authorized gm dealer, all diagnostic test were negative for cracked heads or head gaskets. Suggestive of problem but not definitive. The gm dealer started an oil consumption study d/t having to add 1 - 1.5 quarts oil every 1500 - 2000 miles. In and out of the shop until june 2009 when we experience sudden loss of oil pressure, engine started knocking but not smoking. I changed the oil again and drove the vehicle the next morning. Made it 25 miles when oil pressure dropped again and engine started knocking. I actually drove the vehicle back home under full power but alarms going off and no oil pressure. I pulled the oil pan off and found the rod bearings burned and crystallized. Now looking at new engine. Gm denies problem with that model engine and refuses to offer any assistance. Just prior to experiencing the engine problems we did have to replace the catalytic converter. All of instances started around 80k miles.

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.
