My turning signals work on and off all of a sudden. The first time it happened I was on the freeway and was attempting to get over and my right turning signal wouldn't work but the left turning signal worked fine. Then after a day or two the right turning signal would work but then the left turning signal won't work. Then all of a sudden they would both work then both stop working. Now a month has passed and neither one of them work most the time, but will work for a hot second and then stop working. This is only for the rear turning signal though the front turning signal have always worked properly and still do.

I first started having this problem in October 2015. I purchased this vehicle in July 2015. I trusted this company because I seen they had great reviews. I actually trader my previous car in because it was having problems starting and also shutting off while driving. Now my current car is having probelms starting. I had my battery, alternator & starter checked, and it was good. The company I bought the car from provided warranty coverage on the vehicle. I took the car to get serviced in the beginning of October for an engine mount replacement. They replaced my engine mounts and fuel pump. 2 days after that service I started having issues starting the car. When you put the key in you usually hear beeping noise and I didn't. than my battery light, ABS light, trac off light came on and stayed on and in the message center tracking system light came up. This was very inconvenient due to the weather and having to get 2 toddlers ready for school in the am. I took the car to my mechanic and he replaced the ignition switch. I didn't take it back to the same place because everytime you take it for service my deductible is $100. After 2 weeks after replacing the ignition switch the problem happened again. So I called my warranty service center they said to bring it back but if it needs fixing I have to pay again. (also I am paying a car note of $115 a week). I refuse to keep paying money for this problem. This can be very dangerous in so many ways. It's very fustrating because I trader my previous car (2000 Buick regal) in for the same reason. I'm not sure if it's a wiring issue, sensor issue or maybe when they changed my engine mounts or fuel pump something got disconnected. This problem didn't start until they did service on my vehicle. Please I need some help on what to do. Little minor issues I don't mind keeping up with but something like this needs to be fixed!

My passlock system has been malfunctioning for years now (2007-2015) and at random intervals, my car will not start and I have to wait 15 minutes before the engine will start. Sometimes the "security" light will turn on while I am operating the vehicle and after I have parked it, the security light will flash and I can't start the engine until after the 15 minute cycle has concluded. Not only has this issue been an inconvenience, but I have had occasions where it has put me in danger. I am not responsible for the passlock system failure, nor do I have the funds to repair or remove it. I believe that passlock was a faulty system from the beginning and the fact that it has not been recalled shocks me. I am very afraid that one day the passlock system malfunction will occur when the vehicle is in motion and that I will lose power steering, braking, and other vital operational functions. Noticeably, the passlock malfunction has become more frequent, so I needed to file this complaint. I have talked to service experts at my local Chevy dealership and they have told me on more than one occasion that this issue is widespread, including many GM vehicles, and that eventually my car just won't start anymore. The quoted prices to fix this issue (either repairing it or removing it entirely) have been ridiculously high and I don't understand why I should be forced into paying for a well-known GM/Chevrolet problem.

The service traction control light is on the dash panel and my car started to shake and pull to one side when the brakes were applied. The problem quickly grew into the cat constantly pulls to one side and the steering feels sloppy and loose if that makes sense. The traction control doesn't work but will randomly kick in while driving and the car instantly feels as if the brakes are being applied and grinder but the worse part is how the pulling to one side becomes a quick grab and jerk to one side and has nearly caused me several accidents and I cannot relax and drive. I am always tense and ready to fight to keep my car going straight and now with the bad Michigan winter its impossible to drive on some days. I've been told that I need a new traction control pump which is going to cost around $2500 and up depending on what they find but will automatically start at $2500. That cost is ridiculous and I have talked to prob approx a hundred people who either had the same problem or knew of someone who does, over the past few years. My car is now parked and I have to beg for rides to work because its winter and I cannot put myself and others in danger with this issue. I have to work and Transport kids to different events and feel that this part has to be defective from the start if there's that many people with this same issue. And all of the same exact complaints found online. Please I'm begging you to check into this issue to see if a recall is necessary. Thank you so much.

Anti-locking braking system, traction control, and vsa light comes on under normal driving conditions. Anti-lock system engages and pulsates when the brakes are applied at various speeds and also the vehicle doesn't' accelerate if depressing the accelerator. This could or will cause a serious accident if the system is not fixed immediately. Suspect the wheel speed sensor which is built into the wheel hub. I am requesting this issue be repaired and the factory expense since this is a safety issue and a very well know documented case.

ABS traction control lights on intermittently for 3 years. Had this checked by dealer numerous times and was not able to diagnose a problem. The lights now stay on for the last 8 months.

I purchased from valley Ford 4/18/2009 I have had nothing but trouble with it ever since I purchased it. I have had rocker arms replaced, pins, the aftermarket warranty company wouldn't replace them because they told me that it was not an internal problem, I have had pass lock problems which I had to get done, I just replaced the transmission in 2012 the computer on the car read that it was shift solenoids when it turned out to be the transmission. Now as of the past three months my low beam head lamps will not come on.the day time running lamps work but when it gets dark they shut off & the parking lamps stay on. The only way I will be able to drive is to hold the turn signal towards me, its not the bulbs they have been replaced & its not the fuses and no one seems to know what the problem. My cruise control light flashes on and off while im driving & while the switch is off & also my check engine light flashes on & off but when I take it to auto part store to have it hooked up to the machine it doesn't read anything.....I ask that you guys can please help me with this car, & I also have proof of everything I just wrote receipts and all.

I have a 2003 Chevy Impala. My car cranks fine in the morning. After being driven after a while; I have to wait for it to cool off before it will crank. I have had to wait up to 2 hours for my car to start. I have taken the car to several machines and they are lost regarding the issue. I called the Chevy place and they gave me a list of possible problems and want me to spend $99.99 for a diagnostic test. I told them I was told that it was possible the BCM (body control modular). I have been looking out on consumer pages and there have been response about the BCM being fixed and it only resolved the problem for a short time. Spending $99.99 plus a charge of $450 to $500 to get a temporary fix is way out of the question. I feel this is something that needs to be recalled and fixed asap because this is electrical and can be dangerous to the consumer. I also it should be at a cost to the company due to the fact no one can detect the problem outside the company and it seems that the repair is only a temporary fix and it to expensive for that.
