The seatback failure made a big enough gap between my seat and seatbelt for me to slip completely under my seatbelt. I landed on the backseat floor after I smacked my head on the side rear airbag. I have multiple injuries from the seatback failure and my children would have been hurt from this failure had they b
MY VEHICLE WAS PARKED, RUNNING AND UNOCCUPIED ON THE STREET. MY WIFE ENTERED FROM THE PASSENGER SIDE REACHING IN TO RETRIEVE SOMETHING FROM THE CENTER CONSOLE. SHE PRESSED THE START/STOP ENGINE BUTTON TO SHUT OFF THE VEHICLE. THE CAR STARTED ROLLING BACKWARDS DOWN A HILL, KNOCKING MY WIFE TO THE GROUND CAUSING INJURY. CAR CONTINUED TO ROLL UNTIL IT STRUCK A TREE.
I had minor accident on [XXX] in my 2018 Acura RDX. The front crash sensor was damaged, so the car cannot be returned to me without a new one because the air bags and other safety equipment will not deploy in front crash. The repair shop ordered the part (no. 77930-TX4-A11) from Acura on 5/28, along with other parts needed. Acura's delivery date for this part has changed from 6/24, to 7/2, to 7/11, and 7/18. However, my Acura dealer indicates they've had this part on order since April, and Acura

My car's original security alarm goes off randomly without any reason. When parked and locked in a parking lot next to a street, the alarm goes off intermittently. After unlocking using FOB, the alarm will turn off and then goes off again in a few minutes. This will go on for hours at a time until it stops for a few days and then reoccurs again! Very stressful and frustrating. The mechanic says it's caused by faulty Body Control Module and will cost over $1,000 to fix. I see that many people a
