#349 of 486 REDUCED ENGINE POWER/SERVICE TRACTION CONTROL
Mar 07, 2013 (10:19 am)
I too have started having this issue. Yesterday on my way to work, my 2008 Chevrolet Impala started slowing down and the REDUCED ENGINE POWER and SERVICE TRACTION CONTROL messages displayed. I then felt my rear tires spinning or something. I was afraid and didn't want to get on the highway so, I turned around and went back home. I dropped my car off at a GM dealer this morning and about an hour later they called me saying they would have to replace my accelerator pedal and rebuild the wire harness. The diagnostic they performed was $95 and the repairs they want to do is $910. After reading so many people having this same issue, it is unbelievable to me that there has not been a recall. We should not be responsible for this repair cost. I have not decided what I am going to do. I cannot afford $1000 car repair. I will be picking my car up in the morning and bringing it back home. I have no intentions of buying another GM car in the future if this is how they treat their customers.

Take it to another dealer. I had mine fixed for $200 total at my local dealer. If you search on this form, you will find a link on how to repair it yourself. The part is about $100 and is a real easy fix. I discovered this after I had my car repaired. Since I had the accelerator pedal replaced, I have not had any problems with this issue.

I had the same thing happen to my 2006 Chevrolet Impala last week The problem is with the Throttle Body, it needs to be replaced. If you continue to drive it with the engine power reduced message on it will eventially shut off the motor, and you will have to wait a few minutes before it will start. It was not very hard to replace and only took my mechanic about an hour to fix. The part cost me about $299.00 and the labor was $75.00 When I had the car tested when the engine light came on, the code was P0121 (Throttle Body Sensor) I hope this helps...

VERY good idea. The reps who respond here can only report what they're seeing in our forums - they can't force an investigation or recall. Reporting the problem to the NHTSA is the best way to ensure that all similar complaints are in the same place.

I have a 2009 Chevrolet Impala and my car did the same thing last night on the way home. Without any warning my engine reduced speed and the dash said traction sensor and engine reducing speed. Scared me to death and thankful I wasn't on a frwy and on the feeder. After reading the form, I'm scared to drive the car and now wondering how I'm going to afford to get this fixed which should have been recalled. Contacted dealer and wasn't much help.

My 2009 Impala is in the shop now for the same reason, engine reduced speed while driving and service light came on saying CHECK TRACTION CONTROL. Mechanic said they have to replaced the throddle body and do some electrical and refiguring idle, costing me $667.47. Problem is I don't have the money and can't keep driving the car because it's a crap shoot if the engine is going to stop completely while I'm driving and then have no control of the car and end up dead... I called Chevrolet and the dealer, all I hear is not on a recall and sorry.
