Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“While parked, tried to put car in reverse to back out of driveway but car will not shift out of park. Only way to get car to shift out of park is to apply emergency brakes then shift car into neutral while key turned to off position. Break lights will not illuminate when brake pedal applied. I checked all the fuses and replaced the break lamp bulbs to troubleshoot issue according to owners manual however problem still exists. When researching online I read about the same exact issues occurring in same model and make that were recalled. …”

NHTSA complaint #11119888, filed 2018-08, 172,000 miles

“Car will not come out of park, nor will brake lights operate when pedal depressed. Exact symptoms as described in previous model year recalls. Only wayto get car out of park is to place in neutral after turning key in ignition to first available position, then applying brake pedal to release shift lock.”

NHTSA complaint #10663755, filed 2014-12, 54,000 miles

“Brake light switch at pedal faulty with same symptoms as recall NHTSA I.d. # 04v10600...brake lights won't activate when pedal depressed while driving or parked and when parked transmission range selector is stuck in park position. These symptoms could cause an accident from the rear and or leave family members stranded. Curiously this recall doesn't list the recalled switches part number and certainly ford motors won't admit that a few were installed on 2004 models.”

NHTSA complaint #10494895, filed 2013-01, 137,590 miles

“Car will not come out of park, nor will brake lights operate when pedal depressed. Exact symptoms as described in previous model year recalls. Only wayto get car out of park is to place in neutral after turning key in ignition to first avaialble position, then applying brake pedal to release shift lock. This is a recurring problem w/ a failed brake light switch assembly. It's too dangerous of a problem to not have a recall. Many other model vehicles have been recalled for the same exact problem. Why not this model?”

NHTSA complaint #10717640, filed 2015-05, 95,000 miles

“2004 Mercury Sable headlights go out and immediately come back on. This has happened four times,in complete darkness, each time in a cold vehicle in the morning within 3 miles of home. Three of these events occurred in relation to stopping, starting , or turning at stop sign. One event occurred at highway speed on straight hardtop road. Vehicle is under warranty and has been tested by the dealership where it was purchased and they were unable to find a mechanical or electrical cause.”
