2002 Chevrolet Suburban 1500 Engine cooling Problems

“#5 cylinder 1164 misfires. Collapsed lifter, broken rings. The dealership went on fishing expedition, charging me $271.82 for unnecessary work (new spark plug and wires). Went for second diagnoses, correctly diagnosed this time indicating the above. Mechanic contacted gmpp (extended warranty),told gmpp that the engine should be replaced. The mechanic was advised to tell me to return to dealership for service.”

“On multiple occasions my 2002 Chevrolet suburban stalled while driving on the freeway. After several minutes the truck would restart. The chevy dealer said there was nothing they could do since they would not be able to duplicate the condition. It does not trigger a check engine signal. It usually happens after long periods of freeway driving with no warning. This is not a low fuel issue. I suspect it is a crank position sensor failing after researching the issue on the internet.”

“While driving on the freeway my 2002 suburban with a 5.3l flex fuel equipped vehicle just would stall with out warning and cause me to lose all power steering and other item related to the engine running. I have to wait for the vehicle to cool down before being able to restart it. No code would show on the on board computer and after looking at other recalls it pointed to the crankshaft position sensor going bad. I am going to change it out in the morning. I have read others having this same issue in this year model and think chevy should do something about it.”

“While traveling on busy street, our 2002 Chevrolet suburban suddenly was without power. Pressing on accelerator did nothing and vehicle completely stalled when brake was applied. This left us attempting to navigate from busy street with our three kids in the car with no power steering or brakes! We were 140 miles from home and when we attempted to drive back home, this problem occurred again. This time on busy four lane road with lots of traffic. The vehicle stalled out again leaving us on side of busy road at on ramp location. This was not first time that this has occurred. …”

“Various incidents of vehicle dying while driving on highway when temperatures are high. Does not do it when cold. Has failed to start also. After waiting 10-20 minutes engine may start and continue without problem to destination. Have changed sensor without improvement of problem. Local garage has not been able to locate solution as it is impossible to get it into service when problem occurs. Many problems getting off the road when incident occurs. Have had 4-5 occurrences and becoming more frequent.”
