It came back on again after I had refueled then parked in a place that was not level car was tilted toward driver side which is the same side as fuel door. The failure recurred three times. The contact stated while traveling 65 mph, the vehicle went into limp mode and the service traction control warning light illuminated. The contact owns a 2008 Chevrolet Impala. It is the most unsafe car I have ever driven. I have no problems in the summer, but on the coldest days after sitting all weekend it shows engine hot. Car misses and transmission shifts rough.
The contact stated that the traction control light and the engine light illuminated at the same time which caused the vehicle to reduce power while driving. . I hope I could fix it soon. Once temps go below that I have problems. If this had happened with ice on the road, as there had been that morning on my way to work, a crash would no doubt have occurred as these roads are very slippery in winter. I was able to make it to my destination, but was not a fun experience.
The contact stated that while driving approximately 35 mph, the vehicle stalled and the engine losing power warning light illuminated. I was scared, but had about 8 miles to drive to my home town. The chevy dealership explained to me that they have a lot of problems with the chevy Impala gas pedal. I came to an intersection of a busy highway when I got the message. It has happened since new.
The light came back on at first start the very next day. As I began to cross I was in the cross-hairs of a trash truck on one side and a car on the other. If this light comes on and stays on, it could indicate a drain on the battery that may soon make your car inoperable. The contact stated that while driving approximate 80 mph, the engine stalled without warning. The manufacturer was made aware of the failure. The vehicle was not repaired and was to be taken to a dealer for inspection and diagnostic testing.
The approximate failure mileage was 65,000. The car then reduces power to no more then 35-40 mph and that's with the gas pedal floored. Service stabilitator traction control is the message that I am getting on the dash. A malfunction with the powertrain may see the vehicle lose a certain amount of power, but will continue to run. I have been in the ditch 3 times this winter and its only the first of January and each time I was only going no more than 30mph and swaying all over the road, all the other cars were moving along normally it wasn't bad out, just a little snow. The contact stated while traveling 65 mph, the vehicle went into limp mode and the service traction control warning light illuminated. The vehicle was not repaired.
A year later same problem. This was also told to Chevy by the service manager when they called him. The vehicle has not been repaired. I needed to cross over to the other side. The entire car shuts down and you can not accelerate. The failure mileage was 118,000. The approximate failure mileage was 36,000.
I see some say to replace the thermostat, but the temperature guage drops to lowest reading instantly, which tells me that the engine temperature is not actually changing. First, dashboard warning lights are a sign that something needs our attention or action. The vehicle was repaired twice, but the failure persisted. The vehicle was taken to an independent mechanic where it was diagnosed that the evap sensor needed to be replaced. The contact mentioned that the throttle sensor shut down warning message appeared. Mind you I just picked my car up that Friday from the Chevrolet dealership they changed the throttle body and still the same problem.
Changed the thermostat to be certain and there was nothing wrong with it. I have taken the car to several other dealers and they claim they are unable to determine what is wrong or how to fix it. This has just happened this week and I am trying to figure out what to do about it. It is only a mater of time before I have an accident and injure myself or others. I felt the speed of the car reduced, luckily I am on local street without many traffic.
The traction control system is a joke. I pulled to the shoulder at about 40 mph, turned on my flashers, and continued on to my home. The dealership said its a common electrical problem with gm cars in 2006-2009. In addition, the service engine warning light illuminated frequently followed by a drastic reduction in speed without warning. My son took the Impala to the dealer service yesterday and purchased his 2 tires- it was agreed by service manager that if we took the car there and bought tires from universal that he would put them on, do an alignment and most important install the camber bolt kit at no extra charge. We specialize in new Chevrolet, used vehicles, service, and financing. I though it did it more in wet weather, but today is dry though yesterday rained.
