2011 Chevy Impala - Service Stabilitrak - Reduced Engine Power
As I see on the forums there are many issues with what seems to be the Throttle Body, sensor etc. Here is my wonderful story and I will be updating regularly in the next few days. I will add that I commute at least 2 hours per day and rely heavily on my car for work and to take care of my 2 children - 1 of which is special needs.
Car: 2011 Chevy Impala LS 61K miles (90% of which were highway) Running full synthetic oil - changed every 5-6K miles
Left work last night and not driving for more than 30 seconds when the engine light came on followed quickly by what can only be described and mild to moderate jack hammering of the car and the reduced power to engine message. I pulled over, checked the manual - then Google/Edmunds which brought me here.
I got a ride home after securing the vehicle and came back this morning. Got it towed to the dealership and was told that it was out of bumper to bumper warranty and that it wouldn't be covered under the Powertrain warranty if it was the throttle body or any of the associated sensors.
I'm currently awaiting the call back from the dealership regarding the diagnostic result ($125) and will post everything as it becomes available in an attempt to help anyone else having a similar issue.
It's a shame too - after the research I had done on this car I thought it would be more reliable than my old 2005 Ford Focus. But since May 2013 I've now been left dead by the side of the road twice... first time with a blown thermostat!
So - as I said - waiting on service calling me back. I've also taken the liberty of emailing firstname.lastname@example.org with the details of the vehicle. I'm trying to take a positive approach to this in the hope GM customer Service will pull through for one of its customers... I can only hope they do!
Good luck and safe driving! Updates coming soon!
