It started back in 2002 a few months I purchased my 2002 Impala. It was a used car with 15,000 miles. The check engine and low coolant light came on. Took it to the dealership and had the water pump and low coolant sensor replaced. A week later, low coolant light comes on again. Again took it to dealership and had to replace another sensor. That happen 10 times during the same year. As of now, July 2009, the light is still on. In 2007, my vehicle started to run hot. Was told I needed the manifold intake gasket, thermostat and hoses replaced which would of cost me over $1000. I couldn't afford it. I got a local mechanic to replace everything which he charged me $300. Just recently, I've been having problems starting my car especially after I drive it for a while. I'm a single mother who goes to school and work and this is my only means of transportation. This car has been giving me the blues the past few years and I'm sick of it. All this started with about 150,000 miles and currently I have about 168,000 miles. I will get a better, dependable vehicle later this year and I won't buy another GM vehicle again.

2002 Chevy Impala 7 times in 3 years I had security light issues with this vehicle leaving me stranded I had paid to have this vehicle until I through a fit in December of 2007 GM honored it because the part they put in was faulty. Here it is a year and a half later and I have the same security issue this time it cost me 510 bucks and some change. The car has 50 thousand miles. I will never buy another Chevy period. Since I have been doing many searches on this issue and now see that I am not the only one with the same issue.

I have a 2002 Chevy Impala and I have been having problems with my BCM (body control module). Sometimes when I start it up it will not let me start it up because that security system comes on. It also failed in general yesterday which I figured this out because I had unplugged my BCM and reconnected it and my car started up just fine. I went to the dealership to find out if it could possibly be that because I am not GM certified. But like any other place they gave me the run around and told me it can be something else and something else but I'm pretty sure its this. I have done my research online and most people have problems with there BCM, once they change it the problems go away. I believe GM should fix this problem for free because its something that only happens on Chevy's. I know this because I owned a 2001 Chevy Malibu and it used to do the same thing. This also has happened to me more then ten times in the past four months and its ridiculous. Now I go to see if I can get it fixed and they also told me that if they program it and its not that my money is not refundable and I'm stuck with a car that doesn't work and I loose out around 300-400 dollars.

- Mchenry, IL, USA

Turn signal turns off intermittently. Work fine most of the time. I went as far as replacing all bulbs as well as the fuse. Starts working a couple of months then starts failing again. Seems to be an electrical problem. I've learned on the internet that this is a common problem.

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.

Passlock system failure on 2002 Chevrolet Impala ls. My wife became stranded late at night due to the passlock system failure, vehicle would not start. It took almost 30 minutes to eventually get the car to start and it is now happening more frequently. An internet search turned out literally hundreds of complaints about the problem.

- Aurora, CO, USA

I have a 2002 Impala. The problem is with the electrical system. Specifically, the security light comes on, the door lock fuse blows, clicking noises from the passenger side fuse panel, and on multiple occasions the starter will not turn when the key is placed in the "start" position. This issue can easily be found elsewhere on the internet. We have had this car since Sept 2003. No issues until the last 7 months. The problem has become more frequent and sometimes disconnecting and reconnecting the battery several times fixes the problem. It is a very frustrating experience having to "reboot" the BCM by disconnecting and reconnecting the battery all of the time. My concern is eventually the electrical system will completely fail or worse cause an electrical fire. Others who are dealing with the same issue are spending hundreds of dollars in parts replacements only to have the problem return a couple of weeks later. This "security" problem has to somehow qualify as a recall with Chevrolet/GM. Currently, I am still able to manipulate the electrical system in order to get the car to start. I'm really not looking forward to taking the car to the dealership and be charged enormous fees for parts and labor knowing that this problem will return later on like others have experienced. Please find a way to force GM to do a recall on this problem.

Faulty system cause anti-theft mechanism to activate intermittently during a normal start attempt. The vehicle's message indicator will flash security/battery/service vehicle soon despite having a new battery and a well maintained car with a clean history. The messages always flash together in a cycle, and is always accompanied by the symptoms below: During the above condition, the vehicle will neither crank nor start, or the vehicle will start, with the above indicators, and the radio will lock as well as the disabling of the air conditioner, heat and ability to defog/frost. This creates a dangerous driving condition whereby the windows fog dramatically, completely obstructing my view. The defect has also created a dangerous situation for me in cases where I've had to turn off the car on the shoulder of a highway and have been unable to restart it, and in one instance was subsequently grazed on my arm by a passing car after I exited my vehicle. Several mechanics have linked it to either a faulty passlock sensor, faulty BCM or bad wiring, all of which I was told should last at least the life of the engine, as it is not included in the maintenance schedule. The car has not been modified from it's original assembly and has never been in an accident or other damaging circumstance. The vehicle has also followed its maintenance schedule to a T. the problem has gotten progressively worse and more frequent (several times daily as of 9 months ago) since the initial date of incidence, but because of financial hardships, and uncertainty from representatives at several Chevrolet dealership service centers, I have been primarily using other means of transportation until I can cover what will be an exorbitant cost to repair.

We are the owners of a 2002 Chevrolet Impala ls. We purchased the car new in October of 2001. It has been lightly driven and well maintained. It has had two major repairs; the first being a recall of the steering system, the second, a failure of the catalytic converter which was covered under federal law and replaced. Today, I found out that there is a safety recall for possible fire from dripping oil. That is the basic history. For about a year and a half, we have had a frightening issue with the car. You turn the key and nothing. A light that says "security" flashes three times over and over and you cannot start the car for ten minutes. GM's passlock system, which I believe malfunctions, thinks the car is being stolen. Ten minutes later, you can start the car. The problem is even in the manual for the car. GM admits that, but they say it shouldn't happen as much as I have it happen, like one time is ok, but the 5-6 times out of 10 that my car won't start is exceptional. Ten minutes is a long time with a sick child, alone in a dark place at night, in an emergency of any kind. It is a terrifying safety issue and I have read thousands of complaints all over the internet. GM offered me a coupon towards a new car. I know this is a known problem because it is in the manual and people are frightened and scared about it. This should have been a recall a long time ago since people are being stranded with a car with no fuel supply. Due to the car's computer somehow malfunctioning and thinking the car is being stolen, the passlock system reacts by cutting off fuel supply for a designated period of time, in this case, 10 minutes exactly. GM should be ashamed of themselves for having this issue and doing nothing.

- Dundalk, MD, USA

Passlock sensor issues. Sometimes it just won't start and then I wait the 8-10 minutes for it to reset and then it will start. Been told by the Chevy dealer that it will be about $800 to fix it. I am also having problems with the sensor in the ABS wheels going out.

- Lakeland, FL, USA

Car does not reliably start. My wife has been stranded with our daughter while waiting for the car to start. Gas gauge does not work, turn signals go out without warning. There is no way to tell when or where this problem will occur. Am fearful of my wife being stranded in a bad area while waiting for the car to start. Has been happening for approx. 2 yrs.

- Converse, TX, USA

2002 Chevy Impala 3.8L purchased used in Dec. 2004 w/ 65,000 miles. Where to begin... flooding in floorboards due to clog underneath windshield, three sets of rotors/brakes, clunky noise in steering shaft (replaced twice by dealership) still having same problem, catalytic converter replaced after dealership tried to charge me nearly $1000 to replace; covered by GM as harry green Chevrolet was 'unaware' of replacement policy"!" new struts, numerous alignments/balances B/C vehicle still shakes and shimmys at 60-65 mph; must drive about 75-80 mph just to keep this to a minimum! BCM replaced twice by dealer, security issues won't allow car to start for 15 mins. Each time, which is very inconvenient. Sooo many problems and complaints with these 'quality' GM vehicles, and yet they do nothing to resolve them, except hold out their hands wanting more $$$ from american taxpayers to keep on making junk! and now the newest of a long line of recalls/problems is that there is a fire hazard for leaking oil on the manifold! all of these vehicles need to be recalled due to the numerous safety concerns and consumers are sick and tired of General Motors obvious disregard for safety and reliability!

- Anmoore, WV, USA

Having problems with passlock security system it has locked and will not let me start my car.

- Tulsa, OK, USA

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.

- Bellingham, MA, USA

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.
