Two problems related to check engine light on have been reported for the 2004 Chevrolet Suburban. The most recently reported issues are listed below.
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.
