The car is equipped with an passlock antitheft system that regularly fails. There are hundreds of the same complaints by owners all over the internet. The car won't start for at lease 10 minuted because it thinks it's being stolen. Sometime it won't start at all and I have to unhook the battery and try to bypass the system. I learned that this has happened to others while driving almost causing a collission. The dealership I go to acts like they've never heard of it and can't fix it. It's unsafe for my wife and kid to be riding in.
I bought car 2 yrs ago and drove it for 3 months no problems then sat for 6 months, I start driving it and this is all the stuff that went out and stuff still going on. Radiator temp sensor, water pump, heater, water pump bearing, instrument cluster, low coolant sensor, radiator, vss, key stuck in ignition, lock cylinder, 8 wires under hood shredded in half due to rubbing on belt, power lock wont work on driver side door, chimes go off when key not in ignition. My problem now is key locked up again finally got it to turn then anti theft system comes on and the car wont reprogram codes. My code reader says it cant read from car.
Engine hesitates,stalls, and shifts hard. Had to replace ignition switch and lock cylinder, heat sensor, fuel cap, reprogram antitheft, water pump, always getting bubbles in tires, gauges dnt work, puddle on pass side, heater core, 2 sets of warped rotors, traction control(abs) keeps going off, found wires under hood chaffed( by rubbing on belt I believe)which caused no start. New problems are lights on dash and head lights will turn off at night while driving, I have a coolant leak which I think its due to blown gasket, and tonight I am driving in fog and my front window fogs up in 2 seconds. I wiped w hand and realized I was heading towards a person walkn. Way to dangerous!!!!! I have had car for only 2 yrs. I am divorced w 3 kids and 1 special needs child w lots of appts. I need a reliable car, cant afford new car or a shop to fix car. I have had to become a mechanic cause of this car and I have no time for that, thank god for internet, I wnt take kids in car after dark, it unreliable and thats sad. Please look into issues.
My engine wouldnt start because of the passlock security system chevy had in the 2004 Impala.

The contact waited a few seconds and restarted the vehicle. She called the dealer and was informed that the cylinder on the pass lock system was failing, or possibly the body lock control module or the box sensor. The repair would cost $600. The vehicle has not been repaired. The contact is in the process of notifying the manufacturer. The failure mileage was 71,800 and current mileage was 71,989. Updated 07/28/09.

2004 chevy Impala. Security light goes on and then car won't start. I have to wait about 20 mins. To start. I have taken it to two different dealers over the past 3 years and spent plenty of money but still having problems. Research online has revealed this is a long known problem. When will car manufacturers be forced to 'fess up and fix this? no wonder the big three are going under.
While my complaint may not be 'safety' related, it is certainly an issue. I have 2004 chevy Impala that is suffering from a common and known passlock problem. How can chevy be allowed to produce faulty products? if this is going on how do I know that the safety features on my car will work? I am so disturbed by this.
Car has had several major safety problems (1) defective fuel cap - lead to fuel emissions into atmosphere and malfunction of emission control system. (2) defective speedometer - could have lead to excessive speed, inappropriate speed, and/or crash (3) defective anti-theft security system - can either not allow the vehicle to start, or can cause vehicle to stop running and then not start upon operator command. Could lead to death or dismemberment.
2004 chevy Impala would not start. Security light came on. Called the dealership and was told that the vehicles security anti-theft system can sometimes lockup making it appear as if the car is being stolen. Very expensive to replace. Was told to reset the security system as follows. . . Turn key to on position and wait 10 minutes until security light stops flashing. Turn the key off for 5 seconds and restart the car. This has worked each time we have had this problem, however, my 17 year old daughter was stranded. . By herself. . At 10:30pm in a university parking lot and had no idea what to do. Luckily she had a cell phone so she could call me. I stepped her through the process to get the car started again. This could be a serious problem for young women to be stranded. I searched the internet and found several people having the same problem. . Even in much older models. When is gm going to fix this problem?.
The security lights in my vehicle comes on and engine will not crank for 10 - 20 minutes.
I have a 2004 chevy Impala. It now has 43,000 miles on it. We purchased it Dec. 30, 2004. It only had 13 miles on it. Over the past month it failed to start twice. I took it to the dealer and learned that the passlock sensor needs to be replaced at a cost of $475. 00. After investigating the issue, I've learned that this has been a common failure in gm cars for many years. One would think that this type of failure should not be so common, and especially on such a young car. Gm should be pressured into redoing this system. At $475. 00 per car, they are making quite a bit of money to make these repairs.
I have been having trouble with the car starting. We thought it was the battery. We bought a new one. It did not help. When a mechanic look at it he said that it may be a neutral safety switch. He told me how to start it , first I have to have the key on the on position and the car in neutral to start it. This helped, but I was wondering if anyone else has had any problem like this?.
