My vehicle was returned to me following a torque sensor replacement on 4/9/2026 in poor condition (locked steering and a catastrophic gash in the driver-side tire) rendering it undrivable and unsafe. Crossroads Ford of prince george shop's inspection report claims the tire damage was pre-existing, I have conclusive evidence to the contrary: virginia state inspection: my vehicle passed a virginia state safety inspection on 2/27/2026. Per state law, any tire with a gash or sidewall crack is an automatic failure. This legally certifies the tire was intact immediately prior to their service. Recent tire service: I replaced my rear tires at ok tire and auto on 3/30/2026. At that time, a full tread and sidewall inspection of my front tires confirmed they were in good condition. The timing of the dealership's communication confirms the damage occurred while in their care: I arrived for my 9:30a appointment around 9:25a. No damage was noted during the initial intake. I was in their facility when I watched a mechanic drive to the other side of the service parking lot without being informed of a "catastrophic" safety issue. I was only notified of the gash at the end of the day when the vehicle was scheduled for return. Their staff now deems the vehicle "unsafe to drive" for their own employees. If this gash were present at 9:30am, it would have been told to me before I left the dealership. The locked steering is a direct result of an improper torque sensor installation (which is the reason why I was dropping my car off to be serviced). My car was in driving condition as I drove it to the dealership for my appointment with no issues. I received a call from advisor sade gregory at 11:03 informing me that I would need a steering column now that is on backorder. At 11:13am I received a confirmation for car delivery to me then at 1:06pm confirmation that my car will arrive at my house at 1:15. At 1:20 sade gregory says my car can't be delivered now because its unsafe for them.
Drivers rear shock rusted off the wheel well causing wheel to snap and metal frame to hit the ground while I was traveling 40 mph. At this time the other wheels locked up and started squealing causing loss of control of vehicle shooting me across lanes and hitting curbs on both sides. This was heard all the way inside a church and they came running out. If I had not been able to gain control it would have flipped. The vehicle is available for inspection. It has not been reproduced or confirmed by a dealer or independent service other than the tow truck attendant telling me that the car need to be junk because it could not be repaired. The component has not been inspected by the manufacturer, or insurance company as it only has liability insurance. A police officer did show up on seen to direct traffic around vehicle and did see the issue but no report was taken. There was absolutely no indication that this was an issue until a few seconds before it snapped and that was the wheel started to wobble.
