Three problems related to check engine light on have been reported for the 2001 Chevrolet Suburban. The most recently reported issues are listed below.
The contact owns a 2001 Chevrolet Suburban 2500. The contact stated that the check engine warning light illuminated and the engine began to backfire when driving various speeds. The vehicle was taken to an independent mechanic where they informed that the crank sensor would need to be replaced. There was a recall associated with the NHTSA campaign id number 07v521000 (engine and engine cooling) yet, the contacts VIN was not included in the recall. The vehicle was not repaired. The failure mileage was approximately 96,000.
The check engine light came on, on my 2001 Suburban at 29,000 miles. This was my dads vehicle and was garage kept and driven on trips or to church in rural texas, which is why after 8 years it only had 29,000 miles. I had it scanned at auto zone. A #1 cylinder misfire was detected. I moved the coil, spark plug, and wire to other cylinders to isolate the problem. The scan still detected #1 cylinder misfire even after driving over 50 miles. The misfire was not detectable by the way the truck was running. I went ahead and replaced the injector on that cylinder just to rule it out. Once again after over 50 miles of driving it still scanned as a #1 cylinder misfire. I had planned on taking it to the dealer on Monday, August 24, 2009. On Saturday, August 22, 2009 my wife and daughter were on their way back to the house and the truck died driving down the freeway. They were able to restart it and limp home. I found no compression on the #1 cylinder and took off the rocker arm cover to find a broken spring on the exhaust valve. Had it only been 3 years old it would have been under warranty. This seems to be a bad spring bad luck story. I was curious to know if others encountered the same problem or did the black cloud just dwell over me. Since I can repair it myself I am. This problem might have happened to others without their knowledge since they had it repaired by the dealer. The cost to me for parts is about $350. The greatest cost was gaskets. Repair at a dealer would be between $1500 and $5000 I'm sure (there was a bent valve I replaced, and a mark on the piston I am leaving alone, I'm not sure they would repair just what was needed or go further). It is disheartening when something that should not happen does. There is more I would like to vent here but that is not the purpose of my complaint. I just wanted the complaint registered somewhere. Thanks.
