What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
The contact owns a 2002 Mercury Grand Marquis. The contact stated while driving 50 MPH at night, the cruise control mode malfunctioned, and the speed of the vehicle increased independently. The contact stated that the brake pedal was depressed several times to the floor, but the vehicle failed to stop. The contact turned off the vehicle, and the vehicle came to a stop. The vehicle was towed to the contact's residence. The contact stated that he was afraid of driving the vehicle again. The contact unregistered the vehicle and turned the license plates of the vehicle to the Department of Motor Vehicles. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. Additionally, the contact stated that the check engine and the low oil pressure warning lights had illuminated two days prior to the failure. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 58,000.
?yrs.ago While backing out of parking space at Calaveras Lumber, after shifting into reverse, & removing my foot from the brake; the engine appeared to receive a huge burst of fuel which shot me backward like a rocket slamming my vehicle into and wedging it under the frame of a pickup truck parked in the same lot. I am glad I was parked and had my foot on the brake prior to this unit or system malfunction otherwise the injuries could easily have been fatal on the highway. I think this defect may be a contributing factor to the car dying recently while on my way to a Wedding Reception in Roseville, which left me stranded after dark for 41/2hrs and 71/2hrs. 2days later. I have not been able to start vehicle since and mechanics unable to diagnose why the engine is fuel starved when system parts tested appear to be in good working order. Something seems to be shutting off power or preventing power to the fuel pump and it is not the inertia switch, relays, fuses etc.. Components have been previously inspected by numerous others including dealer. No Recognizable Alert/Warning Prior to Incidents!
