I buckle the seat belt and it just comes unbuckled spontaneously when I’m driving. I check to see if the seat belt is secure by pulling on it. It seems secure but still unbuckles. I usually have to redo my seatbelt every 5 minutes. I do not feel like it will keep me safe in a collision

I have a few good-faith efforts and attempts to bring this matter to COOPER TIRES but each and every time I got the same reply from them NO we cannot help you. We will not be able to warranty your tires for…

2002 MERCURY MOUNTAINEER

Filed Dec 27, 2023


Aftermarket rack and pinion system re-manufactured by Detroit Axel began leaking fluid and caused a loss of power steering within 3 months of purchase. A second unit was installed and after about a year had the exact same failure as the first unit. Also resulting in the loss of power steering. It is my contention that Detroit Axel is not capable of re-manufacturing to a satisfactory safety standard. I believe they should be investigated and perhaps subject to a product recall. I pray nobody…

I unlocked my vehicle, put the key in the ignition and it made a noise, then immediately after that failure to start, everything stopped working. No lights, will not lock doors, no clicking sound as if it were a dead battery.
