Speed Sensor problems of the 2011 Chevrolet Impala

On 1/29/16 my car died and towed to dealer where I was told I need a transmission. The car only had 69000 6months ago dash board lights lit traction control, reduced engine power service stabilitrack abs. When I would step on the accelaretor pedal it would make a winding noise go to the floor and pop back up again. As I was driving down the highway all of a sudden I had no acceleration car had died. L pulled to the side of the road a few minutes later started up again this happened numerous times I told my son he couldn't drive the car because I felt it was unsafe. I called the gm they gave me a coupon to have the a diagnostic check on it. In sept I went to the dealer and he scanned my car for codes I was told I needed a right front hub part number 13582664, a right wheel speed sensor harness, 10340314, accelerator pedal, 84018392, and a vent valve 2085252. I can't believe a car dealers would let a person leave not informing the customer what a safety issue this is. I drove the car for a day because I couldn't afford to fix it and was trying to come up with the money again the car died on me as I went to accelerate now the car is sitting in my yard dead as a doornail. I called the dealer and explain the situation to the dealer at lannan Chevrolet in woburn and I spoke with the owner and the only response I got was what do you want there's a hundred thousand miles on the car I have been doing lots of research on this particular vehicle and I'm appalled between a 2008 and a 2011 there has been hundreds of complaints about the same issue. These are safety issues where people can get killed. Out of all these safety issues there's not one investigation that has been opened in regards to the issues. Nhtsa or gm needs to open an investigation immediately on these cars. There is a major safety issue and a recall is necessary. VIN number. .

The contact owns a 2011 Chevrolet Impala. The contact stated while traveling various speeds, the check engine light illuminated and the vehicle lost acceleration power. The vehicle was taken to the dealer who stated that the speed sensor failed. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 40,000. The VIN was unavailable.

Dec 2013 vehicle hit pot hole while braking at approaching intersection, after that warning lights started flashing abs brakes/tract control/stab control, I was unable to brake, then shut down. Since then temp gauge went bad n was replaced. The 3 above dash warning lights continued intermittently, worse when it rained. At take offs n turns car would jar n abs brake system would pulsate(grabs). Hub/speed sensor was replaced, this did not help. Accessory outlets, when contained w a charger, doesn't maintain contact w power source (such as disconnection/loose connection), causing power surge resulting in 2 iphones to have bad aux ports. May 2014 blower motor started intermittently not working for seconds, then minutes until today sept 6th, 2014 when something under-dash (near blower motor) overheated filling car with smoke, then car shut down while moving once again, car smells awful from the burning! car has been a lemon and not covered under power train! seems like auxiliary elect fuse box(passenger rt foot board), and harness is shot as well as whichever harness is sending power to speed sensor, among many other things I could not mention (problems/defects) due to so many other issues w this 2011 Impala which is now worth 7000 as trade at chevy, I paid 13500 on oct14, 2014! I've checked several ground connects n they seem okay.
