Engine Stall problems of the 2001 Chevrolet Silverado 2500

The crankshaft position sensor has failed the vehicle runs rough. The engine stalls, may re-start immediately or after a cool down period.

Tl- the contact owns a 2001 Chevrolet Silverado 2500. The contact stated that while operating the vehicle the engine would experience rough and harsh idling which eventually progressed to the engine stalling. The contact indicated that the vehicle had stalled on several occasions. The vehicle was taken to an independent mechanic who diagnosed that the crankshaft position sensor was faulty. The sensor was replaced and the failure was remedied. The contact notified the manufacturer of the failures and was informed that the vehicle was not included in the NHTSA campaign number 07v521000 (engine and engine cooling). The contact stated that the vehicle experienced the same failures listed in the recall. The failure mileage was 114,000. Jft.

The contact owns 2001 Chevrolet Silverado 2500. The contact was driving approximately 40 mph on normal road conditions. The engine stalled without warning. The vehicle restarted and resumed normal operation. The failure occurred intermittent. The vehicle is in the process of being taken to an authorized dealer for diagnostic testing. The failure mileage was 60,000.

The events leading up to the failure, this failure mode has happened five times, twice while pulling a 12,000 lbs. Camper and three times during normal driving. When hauling the camper the transmission was in the tow / haul mode. The failure, the 8. 1 l engine suddenly looses engine power and stalls and will not immediately restart. After a minute or two the engine has restarted and normal travel resumed. How often it occurs, since July 24th 2009 this failure has occurred on five occasions. The only common factor that I have been able to isolate is that the failures have all occurred within the first twenty minutes of driving. Its consequences, there have been no crashes but several near misses have been associated with the failures. On September 10th 2009, while traveling along a rural road and approaching a traffic signal the engine suddenly dies without warning. I was able to pull off the road and the engine restarted after a couple of minute cool down period. There were no service engine soon (ses) indicators being shown. I then began to search the internet and found this is a common failure mode with gm trucks that have the 8. 1 l engine from this period and that a safety recall (07v521000) was done on certain VIN numbers to replace a defective oem crankshaft position sensor. What was done to correct the failure;, at this time nothing has been done to correct the failure and the truck is not being used. I feel that gm does not have containment of this failure and that additional VIN numbers including mine need to be added to the recall. From searching the internet, I have found several other failure occurrences outside the containment range. The old part is available and gm should replace the defect before an accident does occur causing injury, death, and/or litigation.

Camper along a state highway 202 in ohio when once again the engine suddenly stalled and I lost all power to the engine, power steering and hydraulic assisted brakes. We were going up a hill and traffic behind me had to suddenly take evasive action since I was no longer accelerating and was loosing speed at a rapid rate. Luckily, there was just enough shoulder width that allowed me to pull over within 300 feet. The engine restarted after a brief cool down period but again I had no idea at this time why the engine had died. There were no service engine soon (ses) indicators being shown. What was done to correct the failure; I. E, parts repaired or replaced (and if old part is available), at this time nothing has been done to correct the failure and the truck is not being used.

On July 24th 2009, I had just merged into moderately heavy traffic on I-70 pulling a 12,000 lbs. 5th wheel camper and gaining speed when the engine suddenly without warning the engine stalled. Traffic following me which included semi trucks had to move to the center lane while I pulled over without power steering to the right shoulder to slow down. The engine restarted after a brief cool down period but I had no idea at this time why the engine had died. There were no service engine soon (ses) indicators being shown.

Same problem as ea06016. My 2001 Chevrolet Silverado 2500hd with the 8. 1l gas engine experienced the intermittent stalling described in ea06016. It was built just after the recall date so gm would not do anything other than offer to charge me for the repair. The main safety problem is the software bug that doesn't record the bad crankshaft position sensor. The first 20 or so incidents were annoying. When the truck started shutting down while going down a 10% grade on a twisting mountain road it got scary. Luckily I wasn't pulling the 15000 pound trailer that I often pull. The problem only occurs at one particular engine temperature and it doesn't set a dtc. It took me three months of searching the web to find the problem. Gm was of no help diagnosing or fixing the problem even with the recall on the identical trucks that were built just prior to mine. My truck had the position sensor replaced in 2002 with the same design part as the original. The replaced part lasted till 2008. Searching the web shows that most of the 2000-2002 8. 1l engines develop this problem at some point. Gm makes a lot of money selling unneeded parts and charging $85 to read non-existent dtcs. An 8. 1l engine is meant to pull large loads. When the engine dies the truck loses power steering and brakes. My truck died at least 50 times before I was able to fix it. I wouldn't let my wife drive it because she would most likely have killed someone with it. It died going around the same corner 5 days in a row. Turning a 7000 pound truck without power steering is a bit of a challenge. I am a test engineer with 30 years of experience. Without the help of the internet this problem is nearly impossible to diagnose. Gm is of no help. The problem sets no codes and the vehicle runs fine if it warms up or cools down from the one temperature. I replaced my sensor and the vehicle now runs fine. There are thousands of more vehicles out there with the same problem. Hopefully you will re-open your investigation.

Engine stall while driving. The engine stalls without notice while driving and at times will not start for several tries. After using a personal diagnostic tool I found the problem to be a crankshaft position sensor malfunction. This is definitely a safety problem because when the engine stalls at 75mph down the interstate and no power steering to help you safely exit the roadway with minimal breaking ability, this should be a concern and recall! the part at a gm dealership is 110. 00 and the charge to get it replaced is not known at this time.
