Truck shuts off while driving. When this happens I lose power steering and brakes. Will occur at all speeds including 70 MPH on the interstate. Very scarey situation that could cause a large accident in rush hour. After researching this on the internet, I have found this is a problem with the make and model truck I have. The problem is the crankshaft position sensor. This should be recalled and fixed at chevrolet's expense!

Engine stalled frequently at any speed without noticed. All power steering and power brakes fail when engine stalls, creating a very serious and dangerous emergency situation. Determined to be failed crankshaft position sensor, original sensor has now been replaced by modified new sensor which was put in service in mid model year 2002. Ask gm as to why recall was not put in to place to replace all previous known defective crank shaft position. Why was the crankshaft position sensor modified and replaced in mid year 2002, if there was such a low incidence of failure. I just experienced a $2,500 repair bill due to gm reluctance to fix a "known" potentially fatal flawed part. Thank god my wife doesn't drive my truck, she wouldn't be able to steer or brake the truck to a stop.

Dt*: the contact stated while driving 35 MPH, the vehicle stalled. After pulling over the side of the road, the vehicle was put in idle and the contact attempted to restart the engine but it would not start. There were no warning signals prior to the incident. The contact was told by a friend that they experienced the same problem with their vehicle which was the same make and model.

(1) - normal daily driving conditions (2) - intermittent failure of the crank shaft position sensor. This causes the engine to stall unexpectedly. There is absolutely no warning when the engine shuts down. Lack of starting can be several seconds to five or more minutes while the position sensor cools enough to return to alignment and allow the engine to start. Shut down has occurred several times while in the middle of rush hour traffic. With luck I was not hit during these un-expected shut downs and in most cases was able to either get the engine started again or was able to pull of the road. (3) replacement of the sensor which chevy has since re-engineered from the original design. The old part is not available.

2002 chey avalanche, 67,000 miles. Engine stopped while driving on the higway. No engine light or other such warnings. Engine started but stalled 3 more times. After a total of 6 sudden engine stops the dealer replaced the crankshaft position sensor. This seams to be a problem with 02 avalanches. Pulling out oto a busy freeway and having your engine stop could be disaterous. Also the action does not generate any codes for the dealer to read cause costly troubleshooting .

2002 chevrolet avalanche 2500 began experienceing intermittent engine stalling while driiving at approximately 38,000 miles. Condition was sporadic but continued getting more and more frequent until vehicle would not restart on june 24, 2005 with 55,000 miles on the odometer. Condition stored no codes on the PCM and was not 100% repeatable. Condition is the result of a faulty crankshaft position sensor which is known to gm and is particular to 2002 vehicles equipped with the 8.1 liter vortec v8 engine. This condition is dangerous due to dramatically reduced steering control and braking power when the stall occurs. Someone is going to get killed as more of these vehicles reach higher mileage !! Sherwood chevrolet replaced sensor on 6/27/2005 at a cost of roughly $200.00

Traveling from texas to florida, vehicle began stalling. At times the vehicle wouldn't shift out of lower gears, at times it wouldn't start, at times it would shut off. Found dealer in florida that changed out a wiring harness in the steering column. The vehicle had less than 30,000 miles at this point. Have also had to have the engine replaced at 50,000 miles. Dealer couldn't figure out why the engine wouldn't work, nor could the dealership repair. Replaced with a new engine and is currently at 30,000 on new engine and problems starting again.

Vehicle has problem with fuel system. Either the fuel gauge goes out indicating that you have more gas than you really do. The fuel pump goes out causing the vehicle to stall. For example, I was driving up a winding hill when all of a sudden, my truck stopped with no warning on a blind curve. This created a safety issue as this incident could have caused a traffic collision. My truck has been to rally chevrolet for this problem 4 times in less than 12 months. The first time was february 2003. The second time was april 2003. The third time was june 2003 and the fourth time was january 21, 2005. There is obviously a problem with the vehicles fuel system. There is also a problem with the cooling system. Every since my husband and I bought the vehicle, we have been smelling coolant after either short trips or long driving trips. There were a couple of times where once the water pump was replaced and then a freeze plug was replaced. To this day, we still smell coolant and the dealer can not find a leak. I don't think this is normal.

It stalls when accelerating from a turn. Mostly on right turns as you accelerate out of the turn the vehicle dies. It starts right back up, but it does this intermittently about once a week. The truck has been to two different dealers a total of 5 times for this problem. Neither one can duplicate the problem. It happened again this weekend. I am afraid that my husband or another member of my family is going to get hurt in this truck. I am trying to deal with gm but they are giving me the run around. They can't do anything if they can't duplicate the problem.
