On this vehicle when you go to make a left hand turn from a stop, the front driver wheel, caliper, or something in the drivetrain locks up and will not allow the vehicle to proceed forward making a left turn. The vehicle only goes forward when you let off the gas then press the gas peddle again. This has been known now for 5 months and the customer is complaining that she almost got into accident, how ever here at dieselz motorsports we had replaced the rack and pinion, front rotors and pads and outer tie rods. And the issue still persist.
The contact owns a 2009 Chevrolet Impala. The contact stated that the brakes, rotors and calipers failed and were replaced.

I was traveling south on 395 goiing to bishop CA. When on the downhill side on stepped on my brakes to slow downwhen the car started to vibrate and shutter violently,when I took the car2009 chev Impala to the dealer they said my rotors were warped,this was at 4200 miles so they turned the rotors . At 7900 miles the dealer then changed both rotors because they warped again,at 13000 miles the dealer changed front calipers and installed a shield kit to help cool the rotors plus turned the rotors again. Now at21000 miles the car shudders and shakes like before and when I called gm cust serv they told me there nothing they can do for me and I would have to pay for the rotors this time. As this is a on going problem that has not been fixed I feel gm is turning thier back on there customers with owell attitude.
