While my wife was traveling on a local neighborhood street my infiniti g37 it began to accelerate excessively. She tried stepping on the brake but the car kept accelerating. She came to the end of the road at an intersection doing about 40 mph and turned to the left to avoid going into a house.
Traveling at approx. 25 mph on a surface street, the front right wheel dislodged from the vehicle, causing the vehicle to go out of control the wheel hit the side of a parked car, and my wife (driver) hit the side of the next parked car, before coming to a stop.

Since that date, I have worked with Plaza Infiniti in Creve Coeur, who has looked at the vehicle a few times and identified that there is no part replacement other than OEM that…
The contact stated that the air bag warning light was illuminated, and the message "Seat Belt Off" was displayed. The vehicle was taken to the dealer, where DTC code: B1018 was retrieved.
