Traction control service reduced engine speed and check engine light appeared on dash while I was driving. I had been driving less than 5 minute at speed limit of 40 mph. I looked this up online.there were many complaints by people having this dame issue. There were people saying their lives were endangered.they were driving and their engine just shut off.this many people having issues with 2009 Impala.this is obviously a defect by the manufacturer. I feel unsafe driving this car. And friends are telling me that Ford cares about the safety of people an takes care of their customers. I am hoping Chevrolet will prove that customers safety is number one priority. And does a recall on this issue asap.

'service traction control' 'engine power reduced' and engine light came on. Car lost all power. I had to wait several minutes before it would start again. I was driving 65 mph on my daily drive of 60 miles one way. Thank goodness I wasn't passing and did not have my children in the car! this has happened several times since where I have not lost all power but partial, the cruise control will quit working and the car has very little power.

The traction control sudden went off - traction control light on and service engine light both on - first time of really cold weather/rain snow. Did it one more time and then traction control light is off and service engine is on - I see that this is a huge problem with the Impala and extremely expensive to "possibly" repair.

2009 Chevrolet Impala. Consumer writes in regards to traction control problems.

- York, AL, USA

Was driving when the traction control light came on and message came across saying service traction control: Then check engine light started flashing rapidly at the same time. Follow by a very loud knocking noise from the engine. Then speed would not accelerate. Turned on flashers and coasted into parking lot. Vehicle had troubles restarting and would not move. Steering wheel was hard to turn. Tries to die while idling after you get it to start. Did diagnostics and code P0300 random misfire detection power train unable to establish a link to the vehicle. Fuel system 2 is ol, lift at 0%, spark plug 13.5, fuel level low 38.8, ECU 14.417, low acceleration. Contacted local Chevy dealership and was told it will cost $35 to tow it to their shop and about $85 just to run a diagnostic on their machine. If it is a lifter the cost will be over $700 to get fixed. I purchased this automobile in August 2013 and have just had it a year. So now I have a car payment on a car that doesn't run. I bought it at wk motors in sedalia, mo. This is the second time this car has had issues and without a warranty the dealership wont do anything!!!
