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.

My dealer says my subframe needs to be replaced, and controll arm at a cost of 3600 dollars, I don't understand why my subframe needs to be replaced, I've owned cars for as long as 20 yrs and never had that problem. This sounds like a manufacturers problem.

90sWhile driving, the vehicle will suddenly display a warning message that says “Stop Safely Now”. When this message appears, the hybrid system overheats and the vehicle immediately loses power. The gasoline engine and electric motor both shut down without warning, even at highway speeds. I am forced to coast to the side of the road, which is extremely dangerous in traffic. This happens after the vehicle has been driven for a short period of time. The cooling fans appear to be running, but the hybrid electronics system overheats and triggers the shutdown safety mode. After waiting for the vehicle to cool down, it will restart, but the problem continues every time the car reaches normal driving temperature. This issue matches the symptoms covered under Ford’s previous safety actions and customer satisfaction programs for the 2005–2008 Ford Escape and Mercury Mariner Hybrid (hybrid electronics overheating and shutdown). The dealership states that no recall appears under my VIN, but the safety failure is identical. The vehicle becomes unsafe and inoperable with no advance warning beyond the brief “Stop Safely Now” message. This defect poses a serious risk of a crash, injury, or death due to the sudden loss of propulsion in traffic.

Me and my wife purchased a vehicle from a private seller to use for personal commute. A month later we started to notice more issue were occurring with the car then stated from the seller. I took it to an auto body shop to get it inspected and possibly serviced and upon that inspection the clerk stated that there was a milage adjustment done to the vehicle. We contacted the seller to try and return the vehicle and receive our money back, but the dealer refused and requested us to resell it.

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.

Vehicle notification stating Power Steering Assist Fault. Power steering locked up on highway going 60 mph while a child was in vehicle and vehicle was extremely hard to get off the highway. Parkway Ford of Pampa, Tx would not honor recall as VIN was not pulling up a recall. But a different auto mechanic repair shop did verify it was a recall.
