Owners report the transmission not holding in Park, causing the vehicle to roll away, and the engine stalling at low speeds or while driving. These failures can lead to loss of control or being unable to restart the vehicle in traffic.
Complaints describe the brake and gas pedals being placed so close that a driver's foot can press both at once, unintentionally applying gas while braking. This design issue raises the risk of unintended acceleration in parking or stop-and-go situations.
The driver's power seat can suddenly slide back to the easy-exit position while driving, making it hard to reach the pedals. This unexpected movement can distract or disable the driver, especially shorter individuals.
Owners report the check engine light coming on and the engine stalling while driving, sometimes requiring multiple restart attempts. Stalling in traffic or on the highway can leave you stranded and vulnerable to rear-end collisions.
“PULLED INTO PARKING SPACE, PLACED SHIFTER IN PARK, TURNED OFF IGNITION, RELEASED BRAKE AND VEHICLE ROLLED BACKWARDS AS IF NOT IN PARK. ATTEMPTED TO RESTART VEHICLE AND NO RESPONSE. SET PARKING BRAKE. COULD NOT GET VEHICLE TO LOCK INTO PARK, SHIFTER MOVED REGA…”

Many owners describe hard or delayed shifts, jerking, and clunking from the 10-speed automatic transmission, with some experiencing sudden loss of power and the vehicle shutting off. These symptoms can happen on crowded roads and may lead to dangerous drift or rear-end collisions.
Complaints include warnings like 'Front Camera Malfunction' and 'Pre Collision Assist Not Available' appearing every time the truck starts. These failures can disable driver-assist features that many buyers rely on for safety.
Exterior lighting is a top complaint area, with recalls for headlights. Owners may face dim or failing lights, reducing visibility and increasing the risk of nighttime crashes.
Engine-related complaints and recalls are common, though specific symptoms vary. Buyers should be alert to rough running, warning lights, or stalling that could indicate underlying engine problems.
“I started noticing hard and delayed shifts from 7th into 8th gear. My RPM's were not increasing when this happened, and then on a very crowded major road I lost all power, vehicle shut off and drifted, then started up and jerked again very hard. This failure…”
“I am reporting a safety-related transmission problem I experienced with my 2020 Ford F-150 equipped with the 10R80 automatic transmission. While driving normally, the transmission shifts hard (ie: jerks, clunks) between 4-5 and 5-6 gears, and has on occasion…”

Buyer analysis
Mercury Mountaineer or FORD F 150: which should you buy?
The Mercury Mountaineer has far fewer complaints per year (about 117) than the Ford F-150 (about 1,131), but the F-150 is also sold in much higher numbers. In practice, the Mountaineer's issues tend to cluster around transmission, parking, and seat controls, while the F-150's reports are more numerous and spread across transmission, electrical, and lighting systems. Neither is problem-free, but the Mountaineer's lower volume may mean fewer overall headaches if you find a well-maintained example.
Key differences
- The Mountaineer averages about 117 complaints per year, while the F-150 averages about 1,131 per year, but the F-150 is far more common on the road.
- Mountaineer owners frequently report the transmission not holding in Park and the vehicle rolling away, a specific safety concern not highlighted in the F-150 sample.
- F-150 owners often describe hard shifting and sudden power loss from the 10-speed transmission, along with electrical warnings for camera and collision-assist systems.
- The Mountaineer has 54 crash-related complaints and 76 injuries; the F-150 has 328 crash-related complaints and 287 injuries, reflecting its larger sales volume but also a broader range of reported failures.
- Test the gear selector in Park on a slope to ensure the vehicle does not roll; listen for any failure to lock into Park.
- Check the driver's power seat operation, especially the easy-exit function, to see if it moves unexpectedly while driving or with the key off.
- During a test drive, pay attention to transmission shifts between gears for jerking, clunking, or delayed engagement, and note any sudden loss of power.
- Start the truck and look for warnings like 'Front Camera Malfunction' or 'Pre Collision Assist Not Available' on the dashboard, which indicate electrical issues.
Before you buy
- Obtain a full vehicle history report and check for open recalls on the NHTSA website using the VIN.
- Have a trusted mechanic inspect the transmission, parking brake, and electrical system, focusing on the specific complaints reported for each model.
- Test drive on both flat and sloped surfaces, including stop-and-go traffic, to replicate conditions where stalling or rolling may occur.
- Verify that all driver-assist features (if equipped) and exterior lights work properly, and check for any dashboard warning messages.
- Ask the seller for maintenance records, especially any transmission or electrical repairs, and be wary of a vehicle with a history of repeated stalling or shifting problems.
