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

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…
