car   Ignition Module problem 2
Failure Date: 08/07/2013

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.

car   Ignition Module problem 3
Failure Date: 08/15/2011

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.

Failure Date: 05/15/2010

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   Ignition Module problem 7
Failure Date: 12/09/2009

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.

Failure Date: 02/16/2007

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.
