Vehicles turn signals stop working intermittently and sometimes will not allow the hazard lights to work. This poses a serious safety risk - I was stopped in a dark unlit area when my vehicle broke down and vehicles were unable to see my car or myself.

I have been experiencing frequent (every day) turn signal failures with my 2000 Impala ls. My Impala has the 3.8 liter motor and 94,000 miles. The hazard switch seems to be the reason for the failure. I have looked at several online "auto help forums" and this problem is an epidemic around the nation. GM has recalled Malibu models for the same exact problem but not Impala. The switch is a $50 part but GM wants $300-$400 to replace it. It is a safety hazard that GM is aware of. Please force their hand in this safety matter. Thank you.

Turn signals fail to operate when lever is moved or stop working when activated. The only way to recover from problem is to press the hazard switch. Then the signals operate correctly. Intermittent problem that occurs about once a week. Dealer said there is nothing they can do even though there is a recall for this very problem on Malibu and Pontiac cars.

- Georgetown, TX, USA

Turn signals functionality intermittently fails. My automobile turn signals failure rate is an estimated 20 percent. I drive my vehicle never knowing when the operation of the turn signals will fail. This is a hazard to myself as well as to others. I have read other 2000 Impala owners complaints concerning this same issue on www.carcomplaints.com. I have discussed this problem with a Chevrolet dealership. They claimed that no recalls or service bulletins existed concerning the turn signals intermittent failure. I have tried to determine what was causing this problem. Obviously, it isn't a blown fuse. Is it a electrical connection, a malfunction of a electrical switch or the turn signal unit?

- Fort Mill, SC, USA

Turn signal not working right sometime they work and sometime they don't.

- Cleveland, TN, USA

Turn signals will not work most of the time. If you turn the hazard flashers on for a minute then turn them off the turn signals will work for a little while. This is a serious safety problem.

- Chesnee, SC, USA

I own a 2000 Impala. From time to time, the turn signals will stop blinking or will not blink at all. If I turn the emergency flashers on and off, they will resume blinking. I know of a Malibu with this same problem. When I mentioned this to the service department where I purchased the vehichle, they knew what the problem was but said there were only recalls on two models and mine was not one of them. This has not caused an accident but I think it is a safety problem.
