Body control module, pass lock sensor, ignition switch. Will not allow car to start correctly often not at all. If research is done there is thousands of complaints on GM vehicles with this system having the same recurring problem. GM refuses to admit that this is an issue with this system. I have not personally had a injury caused by this problem but the potential for an injury is there. If I can not start my vehicle because of this problem it can and has left me in a position that is potentially hazardous.

My 2000 Impala pass lock system stops the car from starting for up to 45 minutes at a time. I try to start the car and it wont turn over or do anything. It happens every time I try to start the car. It leaves my family stranded when we try to go places. What were to happen if there were an emergency? I'd be stranded. Also the steering clunks alot when I turn.

My 2000 Impala has intermittent problems with the direction signals. At times they work fine and other times they don't. sometimes while the directional is working it will stop for no reason. This has resulted in several near rear end collisions even with arm signals. This occurs on a nearly daily basis. I am waiting to see if there is a recall as the cost to replace is approximately $500 as the directional signal is sold as a single unit (directional arm and flashing unit are 1 piece). The unit itself is over $300.

Passlock 2 system fails. Vehicle shuts off and can not be restarted for 15 minutes. This can happen when you are driving or parked. If it keeps happening when driving, it will cause a serious, if not fatal, accident. This theft deterrent system fails 2-3 times per week. The only solution is to replace the lock cylinder, which is about $500 and only available through the dealer. This solution does not always work though. I have had mine replaced twice within a year and it needs it again. GM should be responsible for this and recall it and fix it right. If you search for "pass lock system failure" on the internet, you will see thousands of people having the same problems.

While driving, for no reason at all, my 2000 Chevy Impala just dies on me. It locks up and won't restart for 30 minutes. This happens 3 or 4 times per week. This is extremely dangerous because it has happened at different speeds and road conditions. It has been occurring for the last 30 days. I researched online and found a blog where at least 30 other owners were having the same problem.

My faulty passlock system causes car not to recognize the key and disables the engine for anywhere from 10minutes to several hours. Sometimes the "security" light will appear in the message center while I'm driving, but most times it happens without warning. I will put in the key, but when I turn it, the engine is disabled and the "security" light blinks. I have to wait 10minutes for it to restart, and more often than not, it just trips itself continually and I'll be stuck for 30minutes or more. I have been left stranded countless times in the heat, and dread even stopping for gas for fear that my car won't start again. It is a constant problem when I travel out of town, as I fear that if I stop in a small town, I'll be completely stranded if my car doesn't start back up. Two weeks ago I drove out of town and went 6 hours one way without stopping because the security light was on. This is a huge problem, and a hazard to people's health. It's also dangerous if I get a flat tire on the highway and it won't start back up, then I am in danger for no reason. I've also worried about parking in a scarier part of town, and not being able to just drive away safely if I see some shady people lurking around. There is no fix for this, as the dealer will charge $600 and not correct the issue. My 2000 Impala should be recalled, as this obviously faulty passlock system poses a threat to human health and safety. I will never buy a Chevy, GM, or Dodge car again because of this issue that Chevy has continued to ignore. Thousands complain on Chevy forums but nothing has been done about it. Big big problem here.

2000 Impala intermittently will not start. Suggestion by dealership to wait with key one 5 -20 minutes for the security module to clear then try to start again. Also happening with 2004 Impala.

I have what I am calling the "classic GM passlock problem" with my 2000 Chevy Impala. It started about 2 years ago very randomly not starting. On November 28, 2008 I reported a vehicle problem to the local General Motors dealership. My '2000 Chevy Impala anti-theft warning light was occasionally coming on and vehicle would not start at times.' The dealership charged me $812 to replace faulty passlock module, new ignition switch and cylinder. I'm concern about all the work being done as stated and charged for factory defects, many vehicle owners have had the same problem with their GM auto. In addition, I did not receive a new recoded key. Second, the replacement part for the faulty passlock module was not listed on the invoice as an itemized part ordered and replaced as appear other items. Thirdly, if the part not listed on the invoice, how is the warranty covered? I later learned that the door, trunk and ignition should be operated by one key. And if procedure requires ignition switch lock cylinder to be replaced, new ignition switch lock cylinder should be recoded to old key. Also, passlock sensor was an integral part of ignition switch assembly, but I still paid too much; I am seeking a full refund.

I bought a used 2000 Chevy Impala for my 75 year old mother in law. The car has a problem with starting and the security module. You can drive the car to the store or where-ever but when you get back into the car it won't start again. You usually have to wait 10 to 40 minutes with key in ignition for car to start again. There are a lot of people out there on the internet with the same problem. We already paid over $700 for a new starter and a new security module but that did not fix the problem. Other people claim they have spent thousands replacing all sorts of items at recommendation of Chevy dealerships to no avail. It seems that GM/Chevrolet should institute a recall on this vehicle. It is also a problem in the 2002 and 2003 models of the Chevy Impala.

Veh: 200 Chevy Impala ls yr:2000 fault: In the past few weeks this vech. Has been experiencing faulty turn signals. Sometimes they work and sometimes they stop, and then after cycling the hazard switch they return. I have researched the internet seeking information and I found that GM has done a recall on certain models in the same class year. I also contact the dealer and they said Impala was not part of the recall even if the switch was the same used in the Malibu. (recalled) NHTSA recall number 03V327. I am now unable to purchase a switch in the market because of the recall and the supply has been depleted. (told that from the dealer). In my mind GM should be conducting another recall before someone has an accident.

Passlock system intermittently stalls my car & interferes with the dashboard lights. I have a 2000 Chevy Impala.

- Cleveland, OH, USA

I have a 2000 Impala that does not have traction control. It has a no start problem. It won't turn over and I have to sit there anywhere from 10 to 30 mins waiting for this piece of crap to start. I think somebody needs to make GM recall these cars to fix them. Its time to put the consumer first and not these money hungry corporations like General Motors!!!

- Upper Sandusky, OH, USA

Like everyone else w/ a 2000 Impala I have faulty, non-working turn signals all the way to the major problems of the intake gasket problem to the most severe - the problem of the car stalling while driving or sitting at a light. And no one can pin pointe the actual problem. My car used to just stall out at least once or twice a day while driving. Now the car has given up and I'm about to too. It starts when it wants... I wish life worked that way but it doesn't. today I decided to research recalls on the car and found out everyone has the problems I do but Chevy has not taken care of anyone. Please take note this is serious.
