41 Electrical System problem

Failure Date: 07/23/2014

Recently purchased a used 2003 Impala, I was unaware at the time of the numerous complaints on the issue of the passlock feature. The passlock feature shuts down the operation of the vehicle when it dosen't recognize the key. The key is the matching set for the passlock. For the short time we had the car we experienced a shut down during operation. Lucky for us no one was injured, at approxmate 45 mph the car just shut down and the security light came on. Had to dead steer and brake the car to a stop resulting in the car off the road in the ditch. Tried to restart vehicle, did not even try to crank over. Security light was on at the display had to sit for a few minutes and tried again then the car started. Got it home fortunately without further incidents. Since then there were several instances that the car would not recognize the key and shut down the car. I am very aggrivated that we have to experience such issues as consumers, without any attempts or concerns from the manufacturer to deal with such a wide spread problem. This a serious risk placed on the owners lives with these vehicles. Especially when this has been a long ongoing problem and has been annotated hundreds of times. Why has nothing been done about this, are we waiting for fatalities?.

44 Electrical System problem

Failure Date: 05/16/2014

May 16. 2014 at 6:30 am I parked the car in my driveway after taking my husband to work. I locked the doors after exiting the vehicle with my keys in hand. I was in my home at about 6:42 am when my neighbor began banging on my door and yelling that the car was on fire, I took a look out of the window and came down to get a closer look,stunned there was smoke everywhere and flames under the hood. I immediately called 911 they came it took a good bit of time putting the fire out. I spoke to the firefighters after and he said he believed it"s origin was electrical. We received a quote to repair,replace the engine coolant tube on may 6,2014 from tire discounters and my plan was to drop the car off the morning of 5/16. My husband and I are both heart patients and the loss of this car was devastating. I also would like to add that we had just purchased this vehicle on April 6. 2014 . The car is a total loss. We have the quote from tire discounters,video and pictures from the fire and the report from the incident. I pray for others that didn't learn of this recall in time with tragic results and I am grateful no loss of life occurred here but the pain of trying to get to appointments and getting my husband back and forth to work at honeywell begins again. Thank you for your ear.

Lights would flash interior lights stayed on then didn't work voltage meter would bury to 0 but battery was fine air consign will not work when this happens door locks do then don't work blows fuses trunk will poc open radio will lock headlights flash t I ll I put manual lights on then automatic would work later. Security light flashes a lot of the time all these things start acting up and it continues to get worse. Sometime car will jerk and I have to reset by taking cable off then it works fine. I have kids and I do not feel very safe b in this car.

56 Electrical System problem

Failure Date: 06/01/2013

My 2003 Impala has a security passlock feature which either does not allow vehicle to start or shut vehicle off when it thinks it's being stolen. My vehicle randomly shuts off while driving when this security light comes on, at this point I lose all control of vehicle functions. This is an apparent problem with thousands os gm vehicles that they know about but give no solution or recall to. Instead, consumers are being stuck footing the bill to try and find a solution to a problem no one seems to know how to solve. Please help hold gm responsible and repair our vehicles before fatalities occur. There are pages of posts in several forums online with people having the same issue with no help.

We own a 2003 chevy Impala I purchased it because I thought they were safe vehicles. In the last 2 months we have had multiple issues with traction control and our interior and exterior lighting. We have lost all function to our dash lights our head lights only work when they decide too and my traction control fails to work and when I don't need it engages. . . . . This is not ok! we have had everything checked. All fuses and bulbs are good. We have had diagnostics done a couple of times and nothing ever shows up. I have seen hundreds of complaints about the same stuff. Please tell me nobody has to die or get seriously injured before you make them fix these issues. We all paid a lot for these cars they need to fix them now!!.

62 Electrical System problem

Failure Date: 10/24/2012

When I attempt to start the vehicle, the security light flashes, radio locks up and the car stalls. After reading the manual and contacting a dealer, I was advised to turn the key into the on position and wait for the security light to stop flashing, then start the car. The first time this happened it took over an hour for the car to start. The second time, it took over an hour as well. This is the third time and im on day 2 of leaving the key in the on position and nothing is happening. I contacted the dealer again and at first I was told I needed to bring it in for a security system reset. Then I was told that I need to replace bcm without anyone actually looking at my car. After researching online, there are several complaints regarding this same issue on model 2000-2005. Gm is clearly aware of this defect but refuse recall. Those that have paid over $500 to fix replace the bcm are still having the same issue. Can gm be held accountable for the flaw that they are aware of yet charging people hundreds of dollars to fix a part that may not be broken?.

My turn signals went out. Will not work and idk what's going on but I have read many same complaints the net.

65 Electrical System problem

Failure Date: 08/11/2012

Low-beam headlights have failed to come on and will no longer function. High-beams and daytime running lights still function, but at dusk the low-beams will fail to light; however high-beams can be used instead creating a traffic hazard. I replaced the multi-function switch with a new switch, and replaced the relay with a known good working relay. The relay will still work and actuate indicating that the relay is not the problem. I checked the bulbs and they are still good, fuses are fine, 12v positive power is present at the bulb, but the ground is not activated on either side at any time. All problems point to a bad body control module (bcm). I have checked online and there are many many complaints about this vehicle with the same problem. If the low-beam headlights fail on somebody while they are driving, it could cause a crash and with that comes the possibility of the fatality of the driver and passengers. The bcm computer is known to cause many problems with starting the vehicle, flashing the lights both interior and exterior and these will cause safety issues with the vehicle.

Security lock out, when security light is flashing will not allow to start, have to wait 10 min. And hope that it will reset, when light stops flashing turn key off and then try to start, if not wait another 10 min. Sometimes have to wait 60 min, this is in a dark parking lot after getting out of work at 9:30 pm gm will not recall since ther have been no deaths reported because of this issue.

67 Electrical System problem

Failure Date: 05/16/2012

Security system will not allow you to start the engine, you turn the key and nothing happens, the security light blinks for 10 minutes. If you do nothing after the light stops blinking you might be able to start engine, sometimes you have to let it cycle 2 or 3 times. This is very dangerous for my wife as she gets out of work at 9:30 pm and is alone in a parking lot. Chevrolet knows about this problem and will do nothing as there have been no deaths because of this.

68 Electrical System problem

Failure Date: 04/08/2012

My 2003 Impala LS 3800 car cuts out when I start it after its been sitting a while. I hear this is most common for these gm models but I cannot find out the issue to stop it. Shop workers could not tell at the shop by doing a diagnostic scan. I really want to get this issue resolved.

69 Electrical System problem

Failure Date: 01/01/2012

2003 chevy Impala 87,000 miles on it- security pass lock system begins flashing periodically while I am driving and then randomly will not start. The entire dash lights up and I have power to the windows, but the key will not start the ignition. If I wait 10 minutes, it will start. I took my care to gm service and they said it car need to change some electrical parts like bcm computer, ignition key set, etc etc will cost me around $850 after my research online discovered that gm knows about the issue in their system, but does not care to fix it. In this economy, no one can afford to replace a 850 dollar error. It is disheartening. The reason we went with a chevy Impala is the dependability. I cannot afford this issue and it is simply careless on gm's part. I'm a very disappointed customer and I will spread the word around to not purchase gm vehicles.
