I went out to start my Impala to get ready for work. Unlock my doors as I normally do, and proceed to start the car. It is the chevy key that comes with the car. Anyway, I turn the key and nothing, all I get on my dash is the flashing security light. So I went back inside and done some research while on the phone with my supervisor letting him know that I was going to be late. Turns out, this is a common problem with the Impala of my body style, the ignition switch or the pass lock module. Very inconvenient, this is the 5th or 6th time this has happened, really hurts when you have kids with you and its hot or cold outside. This issue needs to be looked into!.

When starting the vehicle, the engine intermittently starts, runs rough/sub idle then stalls. When the engine starts it seems to run normally, but on at least three occasions, while driving the vehicle the engine would stall and I would loose power steering and brakes. I took the vehicle to jeff wyler Chevrolet for repairs. They had this vehicle from Jan 21 - Feb 11, and replaced the body control module at a cost of approx $435 dollars. When I started the vehicle the conditions remained the same. I subsequently took the vehicle to an independent repair shop (kt automotive llc). They replaced the ignition switch and condition was corrected (approx cost $180 dollars). Note; this condition existed with multiple or no additional keys on my key ring. On 17sept gm recall 14350 was completed on my key(s). Given the experiences described above, this recall will not correct the faulty ignition switch defect on this vehicle.

I own a 2002 Chevrolet Impala. While I was driving 50 mph, the headlights malfunctioned when switching from low beams to high beams. The manufacturer was notified, but offered no assistance. The vehicle was not repaired. Next the car doors would not lock. Ordered new body control module and had it put in and reprogrammed at dealer. Worked for a week and while in drive thru and shut car off when tried to restart car it would not restart but start throwing a bunch of codes. Sat for awhile found seconde set of keys put it in and it started. Apparentl the security system would not recognize the key when it was inserted into the ignition. This locked the contact in the vehicle and prevented it from starting. The vehicle is now in the shop. I have found over 1,000 complaints of the same nature with this car. In 2004 I had new head gakets put on due to the coolant and was suppose to recoup some money. I put in claim and never heard anything. Now turn signals work intermediately. This is a very common issue with Impalas. Very dangerous when I signal I don't know if it is going to work. I have almost caused multiple accidents because of this issue. I complained multiple times to the dealer but they claimed nothing was wrong. As soon as I hit the 100,000 mile.

Purchased a gm certified vehicle. Vehicle stalled several times whenever making a left hand turn. When I would make a left hand turn, the vehicle would die completely in the middle of the turn. I would have to restart the car. One instance when trying to restart the car, the ignition acted "stuck. " I only turned the ignition once and the car continued to crank over to restart the car on its own. The last couple of instances when taking the car to the dealership, it died, even when not making a left hand turn. It would die periodically while driving down the street. I took the vehicle into main motors (a gm dealership) to have it fixed. They said the wires were worn through in the engine compartment that run to the electronic control module. They stated they rerouted the wires. My bill was only for labor, no replacement of parts. I asked gm to cover this. The service adviser told the first agent at gm that it was a defective wire harness. Then the case was directed to a "district specialist. " the district specialist stated that the service manager at main motors retracted the statement that it was a defect and stated it was normal wear and tear for electrical wires in the engine compartment to be worn through. Not a safe design for an electrical system to not last past 55000 miles.

March 2, 2013 my car would not start. The security light had been on and after looking in the owner's manual, it was determined that the passlock system, aka the security system, was engaged and not allowing the fuel injectors to start my car. Upon research on the internet, a lot of tips were provided on how to "fix" the problem. They ranged from disconnecting the battery, taking apart the ignition cylinder and leaving the key in the on position for 10-30 minutes. For other people experiencing this problem, show this official service bulletin from gm #04-08-47-003 to your dealer or repair person! (#04-08-47-003: security light on, engine will not crank, diagnostic trouble codes b2958 and/or b2960 (repair poor terminal connections at body control module) - (Aug 31, 2004)).

On Monday August 7,2012 I started experincing problems withmy car not starting so we replaced the battery. Then sat. August 12, 2012 my car completely shut down. After I got jumped we drove it home only to realize the car wa going only 30 mph. Having to climb hill was very fustrating. Took it to o'rielly and the computer read p0606 which has to do something with the modules. Also all the electrical inside the car is going haywire, key stuck in ignition, and has to lock doors automactially due to keypad not working. Please do a recall on this before someone or family is seriously injured or killed. As a parent I travel alot with mine.

While driving this car it would just stall or die as if someone had reached over and shut the car off and would not start for a few days. I have brought this car to two mechanics and neither were able to stop the problem but told me that different parts were the culprit, so 800 dollars later I have replaced the fuel filter, fuel pump, crank shaft position sensor, mass air flow sensor,replaced the battery, tested the alternator, tested the fuel injectors both hot and cold, tested the ignition module and still the car died leaving my child and I stranded on the side of the freeway in cold temperatures. I then called a gm dealership whom said another 120. 00 just to look at it and said they couldnt find the problem . This is outragous!.

Gm vehicles equiped with the passkey system may, and thousands do, experience a passlock system lockout, where the security system prevents starting of the vehicle, even when using the mfr's supplied key. The passkey sensor problem is recurring even after some consumers had dealers replace it. This defect in the passkey ii and iii as well as the passlock systems on gm vehicles has plagued my vehicle since 3 weeks after purchase. The dealer said I have to replace the passkey sensor, ignition control module, ignition switch, bcm and even possibly the ecm. I have checked with other shops and consumers via online forums and personal interactions, and have come to learn of 1000's if not 10,000's of consumers have this problem, and the dealer recommended repairs/replacements only cover up the problem for about a year. This problem prevents the owner from starting the car, as well as cause it to stall regardless of location or driving condition. This can result in loss of control and possibly leaving a consumer stranded in unsurvivable situations. This is a public safety and a health risk. Even when under warranty, the dealer refused to replace the 'recommended' parts as they were not covered under powertrain warranty, however they cause the vehicle's powertrain to not function or cease function when running just fine seconds prior. Gm has been notified of this issue by myself and to no avail, a resolution is unavailable. I had a friend of mine replace over 8 components of the ignition/security system at the dealer for a cost over $2500. The vehicle was 4 months old. My vehicle, at 9 years has had this problem for the past 4. Gm needs to recall all vehicles equipped with a passlock/passkey 2-3 system for replacement with a more reliable one. A google search turns up over 138,000 results for gm passkey problems. Gm passlock problems turns up over 85,100 results. That is 223,100 results. If I do vehicle specific, that number triples. Chevy passkey problems returns 1,340,000.

Event: use the brakes. Failure: front end shakes. Repair: replace rotors. Event: drive at any speed. Failure: speedometer gone haywire, says your going 20 when you are going 70… repair: rebuilt instument cluster. Event: any time engine running. Failure: temp gauge haywire. You pull over thinking your car is overheating; it's not. Repair: rebuilt instument cluster. Event: any time engine running. Failure: fuel gauge haywire. Don't know how much fuel you have, could run out of gas (did not happen to me). Repair: rebuilt instument cluster. Event: using blinkers. Failure: blinkers either don't work work when activated, or flash randomly. Repair: replace blinker/hazard module. Event: turning ignition key failure: no crank, no start - secrurity light on. Wait a while, car starts like nothing happened. Repair: bypassed and disabled security 'passlock' switch. Event: using wipers/rain. Failure: windhshield wipers stop in middle of windshield, continue after turning off, or don't come on when switch turned on. Repair: replace wiper motor & pulse board. Event: stop at intersection with engine running failure: engine surging and stalling. You must keep your foot planted on the brake so that you don't run into the car in front of you. It stalled out of state in an intersection. Repair: replace mass air flow sensor (maf). This most recent maf problem was the last straw. This car has other non-safety related electrical problems, as well as the normal wear items that you would replace on a 'real car'. This car is a rolling electrical disaster. This car is a money pit, just like its manufacturer. Good luck with that chevy volt.

I have a 2002 chevy Impala. The car behaves as though there is an electrical problem. My own research seemed to indicate a faulty bcm module. I took the car to a dealer and explained my suspicion and the odd intermittent problems, and they replaced the ignition switch and spent a lot of time trying to find a wiring problem. After 2 weeks they said they found the electrical problem and charged me $700. Now, a few weeks later all symptoms are back. When the key is turned on, the lights flash, truck latch opens and closes, and security light flashes. This is just 1 set of symptoms. This problem is very dangerous. . Read more...

Car starts intermittently, at first once every month or so and then got progressively worst. This problem has been occurring over any an extended period of time (9-15 months, maybe longer). Used an independent mechanic the majority of the time (3-5 visits) was never able to identify the problem. However, the independent mechanic was reasonable in his charges. Since 10/23/09 started using a gm dealer (a big mistake). They have changed the body control module and replaced the ignition cylinder with passlock sensor. Cost approaching $1k and still the same problem though with less frequency (about three times since 11/10/09). Contacted gm for assistance and due to mileage (about 130k) they are unwilling to help. Only buy a gm product if you dont plan to put much mileage on it.

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.

Failure Date: 11/15/2008

I owned a 2001 Chevrolet Impala automobile. "security lock" light came on during normal drive 2 days before car failure. On the morning of failure, car doors were unresponsive to remote key. A continuous low droning noise emits from inside of dashboard. When key was inserted into ignition cylinder and turned, nothing happens. Engine did not start, electronic system checks did not come alive. Not even a sputtering sound from the car hood. After checking online for similar problem, profile fits the recurrent problem of passlock sensor of general motor cars. Car technicians quoted me $400 - $600 for replacement of ignition switch and cylinder; $600 on average for change of body control module. . Read more...

The contact owns a 2004 Chevrolet Impala. Occasionally, when the contact attempted to start the vehicle, there was a delayed crank. The vehicle takes several hours to start sometimes. Prior to the failure, all of the warning lights illuminated on the instrument control panel. The vehicle lost all power as if the battery failed; however, the exterior lighting was still operative. The contact also heard a dull humming noise. The contact was advised by another consumer who was experiencing similar failures that the computer chip was not recognizing the key. She took the vehicle to an authorized dealer, but they could not duplicate the failure or provide a sufficient repair. The dealer also stated that there could be several defects with the electrical system: ignition module; however, they were afraid to make repairs because they did not know if either of the remedies would resolve the issue. The starter and battery were replaced, but immediately after the repair the vehicle failed. The failure and current mileages were 52,000.

Vehicle has been stalling intermittently at any speed. Vehicle has stalled a total of ten times. The vehicle has been taken to the local mechanic shop five times and the dealership twice but no codes were found during testing. So far I have had new plugs/wires (tune-up), new coil pack, new ignition module and new crank sensor, and new fuel filter. The vehicle completely dies at any speed. Told possibility of bad fuel pump but dealership cannot be 100% certain this will fix the problem. While driving at 70-75 miles an hour the car completely shuts down. It is a miracle I have not been severely hurt or killed. Problems began in may 2007 and have been ongoing since then.

2002 Chevrolet Impala LS/ 3. 8-v6 the problem started with the ignition switch. It caught on fire. Took in to dealer, after it was replaced, another problem surfaced. . We keep getting the run around at the dealer. . The car intermittently starts. When it wants to. The dealer that I brought it to said he was 80% sure that it was my bcm (body control modules) and he would have to reset my radio. The two repairs would run me about $1,200 and that isn't even 100% guaranteed that it would remedy the problem. What a way to conduct business. I can't believe there are no service bulletins on this. . In doing some research I see the problem is quite familiar on models of the same platform. . I'm at my wits end with this problem. . The car does finally start after sitting there for 10 min or so. . My issue with this is! I'm happy to pay if the problem went away but non of the g. M dealers I've contacted seem to be upfront regarding the matter, and I quote "bring it in we'll take a look at it" that's it! how about fixing it? I reply. . "well we don't know what's wrong with it". . The car does not do it all the time, but a lot of the time. . Usually at the most inopportune time. The problem does not seem to be a new one it's happening a lot. . I'm sure a design flaw. I'm just scared of another fire.
