Chevrolet Impala owners have reported 4 problems related to crankshaft position sensor (under the electrical system category).
No warning, no event leading up to the failure. 2000 chevy Impala LS 3. 8 stalls constantly. No check engine light comes on, so there is no way to know what is causing this. Seems to be a common problem all over just look it up on the internet, don't know why this is not a recall, it is very dangerous. I was traveling 70 mph in the fast lane on a major highway and the car just stalled, also stalled at a red light, also stalled traveling at about 10 mph and at 30 mph (almost rear-ended on both occasions). Chevy does not have an answer, chevy mechanic told me this has been a common problem with all gm cars for years. Why is this not known to the public?
they replaced the thermostat and it stalled about a mile down the road. Now they will try replacing the crankshaft position sensor but will not guarantee that this will solve the problem. Next they would try the mass air sensor. This is a known common problem that could be catastrophic if it happened at the wrong time. I know, I was almost killed on that major highway that day.

My 2001 Impala with a 3. 8 v-6 would not start after golf last Thursday, so I had it towed to a repair shop. The shop put in a new fuel pump, fuel filter, spark plugs and wires. The bill came to $900. I had the same problem various occasions over the next couple weeks and decided to look on the internet. This site popped up when I "searched stalls while driving" because the car started stalling occasionally while driving under just about any condition. I bought a new crankshaft position sensor from car quest installed it myself in less than an hour and haven't had any problems for about a week now. Thanks for the info.

The contact owns a 2000 Chevrolet Impala. While the vehicle was in the shop for repairs (unrelated to the engine) the engine failed. The errors did not appear when the diagnostics were performed. The contact was initially called to come and retrieve the vehicle, but in the same conversation, she was informed that something failed in the engine. The contact was also informed that she should probably get rid of the vehicle. The engine was replaced. Nhtsa campaign id number 04v090000 (fuel system, gasoline:delivery) was referenced. The contact spent $1,000 to have the engine replaced. The current and failure mileages were 78,000. Updated 08/27/08. The consumer stated the crankshaft position sensor, ignition switch and fuel regulator was replaced. Updated 08/27/08.
We bought a Chevrolet Impala new in 2001. Within three years we experienced intermittent shutdowns of the car. Several times the auto just quit on expressways, but getting over to the side of the road we would turn the key off and then it would start perfectly. This occurred perhaps 5 times in the following 3-4 years. It was a dangerous situation. Finally we took it in to the dealership where they had it for 5 days finding nothing wrong. We started calling mechanics, contacted general motors executive offices (an amy green) and other sources. Several mechanics informed me to have the crankshaft sensor replaced. I "forced" the dealership to replace it and have not had a problem since. This was a dangerous situation as a shut down at high speeds a scary proposition. With all of gm's current (2014) handling of dangerous situations, we thought it time to comment on this one. Of course all this gm work was at our expense. I foolishly bought a new 2006 chev. Diesel 2500 pickup and had the whole back braking system rust up within 3 years, but that's a different story.
