Anti theft system keeps on coming on and will not let your car start !!! They even replaced the key holes with fillers in it. You have to turn the key and wait 15 to 20 min. Before it will start or sometime it will not work!!!! How do you explain that and that still does not fix the ignition switch it is a big problem because now the car will not start I have called GM before and they say there is no recall. Well if you look at this web site to see all the complaints in these cars for the ignition problems that should be fixed and they will not do anything about it !!!!! I guess they will have to wait for someone to gets killed again to do something about !!! They already had a big law suite I guess they will have to deal with another one if this keeps on happening when people drive and it just conks out on us and there is a bunch of accidents !!!! …
I own a 2004 Chevrolet malibu Classic. For the past year or more I've been having problems starting my car and the only resolution is to wait 10min. With the ignition in the on position until the theft system light goes off. I figured this out by reading the owners manual but I feel sorry for the many folks who spent hundreds of dollars before doing so. It was only happening every couple of months and has progressed to happening 1-2 times a day. The theft light will now even come on at times while driving. I'm just afraid the car might shut off while driving and cause an accident. The GM dealer says it's probably the ignition cylinder or the body control module that need replaced. From what I've read on the internet forums that has not fixed the problem. …
My husband was taking our four youngest children to school oct. 18, 2005, traveling south on I-45 in the houston area in our 2004 malibu Classic which had approximately 40,000 miles on it. Witnesses said he swerved around several cars and was going 80+ MPH. He pulled onto the shoulder, passed and clipped a car; and then pulled off the freeway into the grassy median. He swerved around a post, a large electric box and a large sign pillar. His left front tire hit a culvert and was flattened. According to an expert, this pulled his car to the left, leaving the car hard to steer. The car hit a sign support structure. All five were killed; the car was demolished and caught fire. According to the police report, this all took place in less than 15 seconds. …
Chevy Classic 2004 would not start. First time this has happened. Out of warranty. Noticed anti-theft light on a few times, for a few minutes, 3 or 4 times in last month. Electrical system, batt, starter, alternator fine. Lots of fuel. Starts in neutral for 2-3 seconds then dies. Passlock assembly, part of the anti-theft system was diagnosed as failed. It is a computer component built-in to the ignition system. Mechanic claims new passlock assembly and new key are required. This vehicle was never in an accident. This vehicle has no after-market parts installed I.e. Radio, alarm, etc. This vehicle is kept in 2 car garage and is only car in the garage.
My 2004 Chevy Classic will not start. Suspecting the theft system. I've dealt with the theft system light before, but this time it has been on solid or not on at all. I've tried the 10 minute restart twice with no luck. I tried a variation of the 10 minute reset that had me do it 3 times back to back without starting in between and no luck. I tried waiting 1 minute and 3 minutes after performing the 10 minute reset before attempting to start it. I replaced the battery with no luck. Diag was done with no answers. From what I've read online, this is a frequent problem with my make and model, and I just don't understand why they don't do a recall.
My 2004 Chevrolet Classic's passlock system is faulty. The "theft system" light will come on randomly and my car will not start. This has the potential to be very dangerous as I live in a desert and right now the day time temperatures can reach up to 120 degrees. The 1st time this happened was in the middle of the day and I was stranded for nearly an hour. After checking several sources online it sounds like this will be a continual problem unless I get expensive repairs done. Chevy should be issuing recalls on the vehicles that have this problem. This started happening nearly 5 years after purchasing this car and is totally unacceptable.
I purchased my car less than a year ago as a certified used car, and the brakes are becoming a very big problem. I have researched recalls that have been made to the make and model of my vehicle and notice that there has been a recall concerning the brakes. I would like to know why, if my car was in fact a certified used car, how it is possible for my brakes to be working so poorly. This problem is one that is potentially life threatening due to the increasing time that it takes to stop the vehicle. This car was purchased less than a year ago and therefore I feel strongly that I was deceived into buying a car that is a death trap!!!
I own a 2004 Chevy malibu Classic, the "unknown car". Unknown for anything worthwhile that is. Anyways this cars theft system from what I can tell is totally faulty and randomly makes you have to wait 10 minutes so your car will start. Resetting the theft system is the only thing that seems to fix the problem of not starting. Maybe replacing the lock cylinder would help but not from what some people say... I haven't tried it yet because it is expensive. So far this has only happened to me 3 times in the last 2 years, I just hope it doesnt get worse.
Ignition key can be removed/falls out when vehicle is being driven. We have had six incidents where we parked car and removed key and then car started rolling. In two incidents an open door of the rolling car caught person knocking them down, one incident just missed rolling over foot. In each case found that car was not in park with key removed. Have also had multiple incidents where key was removed but ignition remained on draining the cars battery each time. Very hard to get key lock into "off" position.
2005 general motors Chevy Classic anti theft system. System will arbitrarily not allow car to start. Have been to repair shop (not dealer) to find this is a common problem. Anti theft light will come on during drive at which time I immediately pull over so as not risk car shutting down. Turn key to on for ten minutes or so until anti theft light goes out so I May continue driving. Several times this has drained battery so I have to wait for good samaritan to give me a jump.
