I own a 2011 chevy impala and for the past couple months on 6 different occasions as i am driving down the freeway my engine power is reduced and "service stabilitrak" light appears. as i have researched and have found that this is a common and very unsafe problem among gm vehicles. i have also found that there is no clear solution to why this is happening with many mechanics stumped and replacing parts in which the problem recurs only a short time later. i have also found replacing what the diagnosis of code p2135 says the problem still may not be solved. as one can imagine that driving down the freeway with a semi,heavy traffic,etc. and losing engine power may lead to significant negative results. i have not installed any parts other than tires after purchasing of vehicle. *tr
Purchased 2011 impala lt/4 door sedan 3 weeks ago. rear center headrest completely blocks the view of vehicle traveling behind, which prevents you from seeing the car in the rear view mirror. this is a dangerous situation. this also poses a hazard when backing up, due to 90% sight blockage. a recall needs to be issued by gm to remove the center rear headrest from this vehicle. the 2012 model of this vehicle does not have a center headrest. it only has headrests on the left and right, which proves this is an issue they have corrected for the newer model. something needs to be done to fix this problem in the 2011. i do not feel safe driving this vehicle because of the lack of visibility. *tr
