“To whom it may concern: please note that I have observed my vehicle a profound amount of water entering the vehicle somewhere within, at, or in vicinity of the front passenger side of the vehicle and driver's side (front). This occurs during rain-fall. My vehicle began displaying an odor and showing white-yellowish colored matter in the carpet area. …”
NHTSA complaint #11162184, filed 2018-12, 61,345 miles“On feb 10, 2020 I was involved in a side impact crash when a large truck failed to stop at a red light. I took the vehicle in for repairs as the front quarter panel and wheel were damaged. The collision shop called today and stated that all four of my impact sensors are dead . He said I was very lucky because there is no way I would've known that my airbags wouldn't have deployed and I very likely would've been seriously injured or killed. There was no warning light on the dash, and no code. They found it by accident on a more intensive diagnostic. …”
NHTSA complaint #11309913, filed 2020-02, 137,000 miles“My granddaughter and I were parked outside a grocery store. We came out with several bags and my granddaughter opened the back lift gate. It went up and then came back down again. It didn't stay up. I tried to open it again with my key and it did the same thing. Went up, hesitated and came back down again. I stopped opening the gate and put bags inside. I took her home then drove home myself. I showed my husband what the back gate was doing. I called the ford dealer I bought my Terrain from last year (february 2017) and got appointment for service today. …”

A month later the vehicle would lunge sharply forward while driving and a heavy shaking vibration (both while driving and at a stop) below my feet in the vehicle (floor board). …”
NHTSA complaint #10569241, filed 2014-03, 44,039 miles“The data I entered for failure mileage and speed at time of incident should not be used as concrete data because for the most part from rolling up very slow driving would be more accurate (without giving gas). I am 47, and driving since 18. I am a mechanic, worked telephone, data, presently a nurse. I have driven many cars. I have owned, or co-owned a least 15 cars. I am always on the road in all conditions. All my past professions required plenty driving. I have driven the above mentioned vehicle for little over 2 months. …”
