Example complaints

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

“I had just got home with my vehicle from the repair shop, had a vacuum hose replaced. I could not get my key out of the ignition. I kept trying & was finally successful at removing the key. Now the gear shifter is stuck in park and will not go into any other gear. I just got it back from the shop & still can't drive it due to getting it in gear. This really does need to be looked into & they need to do a recall. I have seen a lot of complaints about this problem. I have 2 more years to pay it off & then it is gone.”

“There is a high frequency sound emanating from all 4 speakers. This noise is constant and can be overheard with the volume up and the radio playing. Leith Lincoln (raleigh,nc) denied the problem. Ford dispatched an engineer and their east coast customer service rep. All claimed they could not duplicate the problem. I then confronted leith with a video tape of the noise and got a confirmation that the noise is at least a nuisance. I've been in contact with ford and they will not fix the problem. …”

“There has been a unprovoked crack in the lift gate panel for a couple years now (which seems to be a very common problem in this model), we have not had issues until the rear window started flying open while driving at around 30mph. The latch has malfunctioned due to water seeping into crack.”

NHTSA complaint #11010322, filed 2017-07, 75,000 miles

“Transmission shifter breaks and locks in place. The result is to leave the vehicle occupants stranded in a dangerous neighborhood where their personal safety is at risk. The problem is a broken $5 piece of plastic contained within the shifter knob. However, ford refuses to supply the $5 piece and instead requires the vehicle owner to purchase the entire shifter assembly (which costs almost $1000). Based on the number of backorders for this piece at any one point in time, it is apparent that ford is aware of the problem and is not taking steps to remedy. …”

“The contact owns a 2003 Lincoln Aviator. The contact stated that while driving 40 MPH, the engine warning light illuminated as the vehicle started to shake abnormally. The vehicle was taken to the dealer who inspected the failure and advised that the cylinder head in the engine needed to be replaced. The manufacturer was notified of the issue who offered no assistance. The failure mileage was 92,000. Updated 8/23/12 also, the ignition coils needed to be replaced. Updated 09/05/12”
