NHTSA complaint #11121594, filed 2018-08, 150,000 miles“I was making a left turn on a parking lot when I heard a loud crunch coming from the front of the vehicle and fully lost control of the car. When I came outside to see what happened I saw that ball joint on my front left (driver side) broke, the wheel with part of the axel fully out, and that break fluid was spoiled all over. Imagine this happening on the fighter when I was driving with two of my young kids!!”
NHTSA complaint #10822207, filed 2016-01, 65,000 miles“I was about to leave from my residential parking lot. I went to check my wheelchair was secure. I opened the liftgate. After securing the wheelchair I pressed the electronic button to close the liftgate. I heard 3 beeps, but the door/liftgate would not close.I turned the car off and on, I got out the manual began to try several things to close the door/liftgate. I locked and unlocked the door locks, I checked nothing blocking the sensors. I used the power control button under the dashboard and the door still would not close. I did this for an hour. …”
NHTSA complaint #11187082, filed 2019-03, 70,000 miles“One day, my keyless don stopped working. The next day the door kept locking while I was driving almost every time I turned the steering wheel. Then the drivers door wouldn't unlock, when I manually unlocked the door it was hard to do. I luckily had the windows rolled down, got out the vehicle and as soon as I shut the door I hear the door lock and my two year old was in the backseat! Again luckily I had the windows rolled down otherwise she might've been stuck! Then the alarm kept going off and wouldn't turn off until I unhooked the battery. Imagine my frustration. …”
NHTSA complaint #11246517, filed 2019-08, 106,000 miles“When accelerating after driving for a few minutes maybe 10-15 after the vehicle has had time to warm up, as I am applying pressure to the gas pedal and it is shifting into gears (usually into gears 3,4, & 5) the vehicle is showing that it is into the next gear but you feel it shift after the fact so it is delayed and as accelerating it feels as though it is lagging and trying to shift but can't fully right away. I am only submitting this complaint because I know a couple others with this make of vehicle but different years and they stated they have the same issue with their vehicle as well”
