“TL* THE CONTACT OWNS A 2015 CHEVROLET SS. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE LOSS POWER STEERING FUNCTIONALITY WITHOUT WARNING. THE VEHICLE WAS RESTARTED AND THE VEHICLE TEMPORARILY REGAINED POWER STEERING FUNCTIONALITY PRIOR TO THE FAILURE RECURRING. ADDITIONALLY, THE CONTACT ALSO EXPERIENCED THE FAILURE AT START-UP. THE VEHICLE WAS TAKEN TO CLASSIC CHEVY SUGAR LAND (13115 SOUTHWEST FWY, SUGAR LAND, TX 77478, (281) 969-4132) WHERE THE MECHANIC REPLACED THE STEERING GEAR AND THE STEERING RACK. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND A CASE WAS OPENED.

“The contact owns a 2015 Chevrolet SS. The contact stated that the service air bag warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed and determined that the passenger’s side seat sensor needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure informed the contact that the vehicle would be repaired at her expense, with a possible reimbursement. The failure mileage was approximately 140,000.”
“Noticed a noise in the front suspension and took it in to dealership to get looked at. Dealership inspected and told me some internal component of the strut had failed and it wasn't operating correctly. I asked if I could just continue to drive it and they told me it could be a safety issue if I didn't get it fixed. My vehicle only has 39,000 miles and I found it very odd for this component to fail with such low mileage. After doing a little research, it turns out there are many reports of both the front and rear suspension components failing on these vehicle when they were not very old and had low mileage. I got it fixed and don't have the component in my possession. Dealership told me it was a safety issue. The component has not been inspected. No warning lamps, messages or other symptoms of the problem prior to the failure.”
