Vehicle speed control

2 reports1 crash
“CAR WILL STOP ACCELERATING WITH NO WARNINGS THEN WILL START BACK MOVE WHEN YOU LET THE SIT FOR AND HOUR. ENGINE LIGHT WILL NOT LIGHT UP WHEN THE INCIDENT HAPPENED SO THE PROBLEM CAN NOT BE DIAGNOSED UNTIL THE ENGINE COME ON. HOWEVER WHEN THE ENGINE LIGHT DOES COME YOU CAN TAKE TO DEALERSHIP AND THEY WILL TELL THAT THE TRANSMISSION SPEED SENSORS NEED TO BE REPLACED IN WHICH THE SENSOR IS LOCATED INSIDE THE TRANSMISSION AND IN CONJUNCTION TO THAT IT IS RECOMMENDED THAT THE VALVE BODY SHOULD BE REPLACED ALSO. THIS HAS BEEN A PROBLEM WITH A LOT OF THE INFINITI'S WITH YEARS RANGING FROM 2014-2019 WITH 3.7 LITER ENGINE. THIS PROBLEM SHOULD BE RESOLVED BECAUSE THE CAR CAN SUDDENLY STOP MOVE AT HIGH SPEEDS AND CAUSE AND ACCIDENT. PLEASE TAKE A GOOD LOOK AT THIS RECALL AAMCO TRANSMISSION HAVE HAD HUNDREDS OF INFINITI'S WITH THE SAME PROBLEM AND THEY CAN NOT REPAIR SO THEY WILL SEND YOU TO THE DEALERSHIP FOR REPAIRS IN WHICH IT WILL COST THE CONSUMER 3,000 PLUS TO FIX THE PROBLEM AND THEY WILL RECOMMEND THAT YOU SHOULD GET THE TRANSMISSION REPLACED INSTEAD OF REPAIRING IT AND MOST OF THE VEHICLES ARE HAVING THIS PROBLEM WITH LOW MILEAGE.

Air bags

1 report
“Driver side airbag deployed as I was turning the corner leaving me with no visual of pedestrians. The deployment resulted in lacerations on my forearm and a knot on my head with a busted lip. My vehicle is technically not drivable because my seatbelts are locked. I am also afraid of driving my vehicle due to the other airbags deploying on my family out of no where. There were no prior lights or warnings to this incident.”
