The contact owned a 2021 Mazda CX-30. The contact stated that her husband was driving 60 mph on cruise control and while approaching a traffic light he depressed the brake pedal but failed to deactivate the cruise control and stop the vehicle. The contact stated no warning light was illuminated. The driver steered to the right and crashed into another vehicle. The contact stated all the air bags did deploy.

Involved in an accident low speed on 3/17/23. Upon impact with other car passengers seat belt did not activate until passenger hit dash with her head and then it apparently engaged and threw passenger back with tremendous force injuring passenger. Upon inspection at the body shop they found the following code: U0452..invalid data received from restraints control Panel. History. They will be calling Madza for inspection. This needs to be inspected as soon as possible before someone gets killed.
I was involved in a traffic accident on 6/29/23 involving myself and my [xx] year old son, both in the front seat. We were struck in the back by one vehicle, spun out of control, hit another vehicle on the passenger side where my son was sitting and spun out of control again. Driver side did not strike anything and side airbags deployed (both front seat and back seat), passenger side airbags never deployed. My son's safety was put at risk as the damage was extensive and the car was totaled.
After turning left at a signaled intersection onto a highway the automatic braking engaged and the car skidded to a stop in the middle of the lane. Luckily nobody was behind us. There was a car about 4 car lengths ahead that was going the same speed and was not stopped. I pulled over and checked the front sensor and noticed a couple black flies on it and brushed them off.
