This is a pass-lock problem. Randomly the pass-lock system on the 2002 Chevy Impala I own will not allow the car to start. I wait 15 minutes and the car starts. My understanding is that this is a common problem with the Chevy Impala and it causes me lots of problems. I am late for work, late picking up people, sometimes it happens when I run errands so I have to sit in the parking lot and wait for it to reset. A huge waste of my time. The reason why I am writing today is that it just happened this morning and I have finally reached the end of my rope.

There were no events that lead to this failure. With all fuses operational, I do not have any dashlights illuminated at night. I have to use my cell phone light to place over my speedometer cluster panel to view my speed, gas levels and any warning lights. This has been ongoing for a little over a year. When my daytime running lights are on, they blink constantly and other drivers think I am experiencing an emergency. If I use my interior lights, they flash like I am trying to signal for help. Same if I open the visor to use the lighted mirror. I have not had this repaired since GM will not guarantee a resolution with a repair. I cannot afford to keep giving money to GM dealerships without a repair. This is very dangerous for me at night, I cannot use my cruise control everywhere. My traction control will not disengage either.

When driving at night and using the "high beams, " they go out after awhile. Nearly crashed until I could slow down enough to safely stop! by moving high/low beam lever, I was able to get headlights to come back on in the low beam position. In checking NHTSA web site, found this is a problem General Motors is aware of but expects owners to pay for repair of poorly designed part.

The passlock seems to be failing on my 2002 Chevy Impala..74,000 miles. When I attempt to start it, nothing happens, and I have to wait 10-20 minutes before I can start it again. This has happened 3 times since March 2008.

On many occasions, car will not start after sitting for several minutes. This has happened since new and it has been in the shop many times to be fixed. Lots of money spent and no resolution. Leaves my elderly parents stranded and could result in major issue if in the wrong place. Someone needs to address this issue - GM is not!!!

Car would not start changed passlock and still will not start. Security light is on, radio is locked and the Chevy dealership does not know what is wrong with it, they are guessing that is the BCM and the SDM but they cannot promise that it will work.

2002 Chevrolet Impala ls - security/passlock system problem - summer 2007 - took in to Chevrolet dealer (since out of business - palm bay Chevrolet in Florida) because security light would come on at times, eventually disabling car for short periods of time. First repair, BCM replaced - same issue two months later - ignition cylinder replaced - two months later, security light would come on again. Dealership out of business that did two original repairs for $1200 - today, security light was flashing and car would not start. Looking online, this is a very common issue with Impala from 2000 - 2005 - why is there no recall?

Initially started with the engine not turning over. Full battery power, put car in N to start, nothing. Put car in emergency park to start and it did. This happened repeatedly, with no warning. Now the car starts every time. The problem now is interior/exterior lights flash like strobe lights every time I start my car till the time I turn it off, so I can't drive at night. The "security" light pass lock issue interferes with the A/C compressor and will blow hot air. A constant clicking from the relays in the passenger side fuse box. Why is it many GM dealerships across the country cannot diagnose this when consumers have brought in the vehicle for assessment. Check out the website of carcomplaints.com for more of the same issue. Fellow Impala owners; lets file class action law suit again GM to get this resolved. But sadly it will take one death or more for any action from GM. "the american way is lets do something after the fact and not be proactive to prevent".

At random times, the car will not start when the ignition is turned. There is no response from motor at all. The security light will flash on the information center display when this happens. After waiting 10-20 minutes the car will start. The first incident occurred about 1 year ago and has been occurring at random times ever since. Vehicle was taken to a GM dealer service department after the first time it occurred and they were unable to diagnose the problem. Since then I have noticed that the fan for the HVAC system will not work at times and the security light and other lights will appear on the information center display at random times.

I own a 2002 Chevy Impala. On 5/20/05 the security light started coming on and would remain on. The security light continued to come on and now the car would not start. It would take 10-30minutes before I could start the car. I took the car to a dealership and they replaced the ignition cylinder. On 6/15/05 the same exact problem started up again. This time the dealership installed a new starter. On 7/16/05 same problem arose again with security light. A diagnostic was done and codes came up from a notice from GM (8/04). The code #'s were B2958 and B2960. The code said to repair poor terminal connections at body control module. The security light continues to come on and car does not start. This continues on/off from 9/11/05-11/28/05. On 11/28/05 the ignition lock/sensor is replaced and the PCM is reprogrammed. And I am given a new key. Looks like at the moment the problem is solved. Well today 7/17/08 I notice that the security light is back on and I begin to cringe because of what I went through in 05'. I get online to see if anyone else is experiencing the same problem and I was shocked to see the # of complaints from disgruntled customers about this security light. This is an outrage! GM by now is well aware of the problem with this security light going on. It would seem to me that there would have been a recall notice going out to Chevy Impala owners. I have contacted GM. My complaint is on file. I have 2 file #'s. one for in 2005--# [xxx] and a new one just started today (7/17/08)--#-[xxx]. please google Chevy Impala and security light problem and see the list of complaints that come up. This is an absolute disgrace! I feel that this is something that needs to be looked into asap.

20002 Chevrolet Impala, frequently does not start about one in every ten tries. I have taken it to two different mechanics one said could find nothing the second time I left it at the garage for a week and a half before it wouldn't start for the mechanic. He checked the codes and they said it need a new ignition switch. I am reluctant to install a new switch because of all of the complaints with this year and model car and in many cases a new switch and computer did not correct the problem.

The air bag light began illuminating with the radio locking out on our 2002 Impala at 15,630 miles. Love Chevy Hummer reset the computer. Later the same problem recurred. At 16,009 miles love Chevy Hummer replaced the inflatable restraint sensing and diagnostic module. Later, the same problems recurred many times but, we found that we could reset the computer by shutting the car off, opening and closing the door and restarting the car. At 23720 mile the car was taken back to tuscaloosa Chevrolet. The computer indicated the problem was the body control module. It was reprogrammed. Several weeks later the same problems recurred over and over. We took the vehicle in to barkley Pontiac, Cadillac, GMC. The computer code indicated a body control module wad needed but that since the car was out of warranty I would have to pay for it. It was not repaired at this time. While driving at night the headlights went out. I was able to get them back on by flashing the low beam / high beam leaver. Notified General Motors customer relationship specialist spoke with carley leblanc. (service request: 71-437167435). After several emails and phone conservations we were told us to fix it ourselves if we were so concerned. We sent addition information to carley leblanc and later angelina moncivais contacted about our complaints. After several more emails and phone conversations angelina said she was not able to help us. In January of 2008 all warning indicators started cycling and the warning bells started ringing. On February 6, 2008 the Impala would not start. I charged the battery and on February 15, 2008 took it back in to tuscaloosa Chevrolet. After another diagnostic check was told the body control module would need replacing at a cost of nearly $600. Called GM asking for help since the same problems with the car have occurred since it was purchased new on June 6, 2002. After about 2 weeks of phone conversations we were told there was nothing GM would do.
