My service traction system and ABS light stays on constantly when I am driving. I don't know what kind of problem this is could you possibly tell me some information and if there's a recall.

I have had my 2004 Impala into the shop three times now with regards to the traction light going on when I turned along with trac off and ABS warning lights going on. Initially the service lights would go on when turning right or left. The ABS would make a noise like it was cycling. Just last week on the highway the traction service light went on while driving at 60 mph. I have had to stop and the brakes would pulsate with no braking capabilities then it would catch and I would be able to stop with pumping the brake. I almost had an accident. The first time a repair was made two weeks ago and replaced wheel hub assemblies on both front tires and front brakes were replaced. This is time frame went the brakes went out. I was told the back brakes were ok. The second time - the mechanic replaced the right bearing after the lights went on again after 5 days of driving. Now it is in the shop to replace the wire harness for the traction and ABS when the service lights went on again. The wire is rock hard.

The traction control light came on before the snow and ice came and then on my way to work with no warning when the brakes were applied I had no brakes at all. I slid right through a busy intersection with no warning. The ABS braking system does not work at all in the snow and ice. I was very lucky the cars were spaced out, that kept me from a very serious accident. I have read online that alot of other people are experiencing the exact same problem with the same make, model and year of car. My question is why have they not issued a recall on the 2004 Chevy Impala before it kills or seriously injures other people.

The traction control turns on frequently. This causes the car to make a grinding noise. When braking the car makes a grinding noise and car is not stopping it feels like it's locking up and sliding. In a sudden stop needing to be made is at great risk of a accident. I have replaced a elbow shaped part that has busted open twice. Car is constantly over heating the radiator cap has a rustic clay like substance. It won't hold antifreeze, I don't see a leak but it needs refilled quite often. The engine smokes, the cars RPM's will flex up and down and the car will just cut off. I'm wondering if the rustic clay like substance has gone through my engine and is causing me many problems with it. I have found reports of lawsuits in past regarding dexicool in GM cars doing this and ruining the engine. The problems in the reports are just like mine and many others on here. Help!!'

I have a Chevy Impala and the service traction light comes on, the traction off light stays on and the ABS light stays on then when you use your brakes it is like the brake is pushing your foot back up. This is going to cause someone to get hurt. I have replaced the wheel bearings 5-6 times in a year. It will work for a very few months and then it starts all over again. Last Thursday I had put an expensive set of the wheel bearings on it and brakes all way round on the car. It did not make it out of the shop before all of these lights started coming back on. So I had new wheel bearings put back on it again today and it is still doing this. GM needs to have this problem fixed. They should do a recall and fix this problem, from what I can read on the internet there is a lot of people having this same issue and it is costing everyone a lot of money.

The ABS light on my mother's 2004 Chevrolet Impala (only 32,000 miles) ABS light recently started coming on. She took it to the local GM dealership. They referenced a GM service bulletin that requires replacement of harnesses and sensors. $367 dealer would not cover warranty because of vehicle age despite our complaint. We elevated the issue up to GM district service (case# 71-898488738). After several calls GM has offered 50% back. Regardless, it is unacceptable to not policy safety system beyond standard warranty coverage. Questionable if this should be recall. We found four other complaints and one investigation in NHTSA data base of same issue.

New 2004 Chevy Impala ls first use 3/23/05. Three times since purchase I've had to replace a wheel bearing & hub assembly. March of 2006 the right rear, January of 2008 the left rear, October of 2009 the right front. Each time the ABS and service traction system lights were on. I paid $636.31 this last time. This appears to be a poor design and a safety issue which could lead to the car being undriveable. I was told that the tires would begin to wobble and the steering would be affected if not repaired within a certain amount of time. I've seen on line I'm not the only one who has had a problem with this defect. I'm concerned that the 4th one will fail, or the other 3 that have been replaced will fail again. I am #1 concerned with my safety & the safety of others on the road. I am also concerned about the money I've had to pay because of this design defect.

When I give it a little gas to go usually just when im first taking off the traction control kicks in but if I let off the gas it kicksback off. Then again, go a few blocks and hit the brakes and the antilock brakes kick in some times it turns off the traction control and ABS it seem like this is a problem with a large number of Impala and every one is shelling out a lot of money and still have the problem I don't have that kind of money can you tell me what is wrong or should I trade it in for a Ford I am 46 and have always been faithful to Chevy but if im stuck with a factory defect Ford here I come.
