Three problems related to check engine light on have been reported for the 2002 Chevrolet Suburban. The most recently reported issues are listed below.
While driving vehicle losses power, reduced engine power light comes on. I have taken the Suburban to the mechanic. Change the maf, tps, air filters other sensors that the diagnostic test has pointed out as problems and have had a vehicle tune up done (new spark plugs, wires, oil changed, etc. ) the cost of these repairs has been over $1000 and seem I will be spending more. The problem continues to happen. Reduced engine power while driving. I am afraid this could cause an accident and cause injuries or even death since it happens while driving.
The contact owns a 2002 Chevrolet Suburban 1500. The contact stated that the vehicle would stall without warning when driving various speeds. The failure recurred over a span of several months until the check engine light illuminated and remained illuminated. The contact stated that he was able to restart the vehicle after each failure. The vehicle was not inspected or repaired. The VIN was unknown. The failure mileage was 120,000 and the current mileage was 121,988.
2002 Chevrolet Suburban 1500 loses acceleration power on highway. Vehicle does not respond to acceleration attempts. Once brake is applied vehicle completely stalls and has no power steering or brakes. This has occurred in highway driving at 70 mph in heavy traffic areas. There is no consistency in occurrences. Happened August 2007 , and Dec. 2007, sept. 2009 and November 2009. Check engine light does not come on. Can not be diagnosed on computer. Gm mechanics can not figure out problem unless it happens to them. Gm refers us to dealership for diagnosing and repairs under these conditions. Don't have the money to put in repairs that may or may not correct problem. Have found many complaints on internet detailing this problem but gm denies any knowledge of this problem. Noticed that 2001 chevy Suburbans have had a recall of crankshaft position sensor and that symptoms are similar to my vehicle. This problem poses a tremendous life and death safety concern for me and my family especially when we are traveling in high traffic areas or in mountain areas.
