Hood on front car fell closed by itself and latched closed. My fingers were on fender at the time it fell. My fingers were smashed between the hood and the fender. I could not get them out. I had to scream for someone to open the hood from inside the car since I was trapped.
Rear axle assembly fell apart and dropped front end onto the pavemnent.
The tire and rim assembly on the right front corner came off damaging the front fender (ohio traffic crash report). Nlm
Brakes are not adequate for the vehicle, very weak in spite of good linings.
The service advisor (dick smith I think his name is) assured me that scheduled maintenance would address the engine surge problem and as I think about it I agreed to it because that was at least the second time I was in lindsay cadillac for service on the engine surge.
After discovering that the vehicle was not driving right owner checked the wheels and found the left front wheel to be cracked and coming apart. Spokes were coming out of the wheel. Customer was notifed about the problem. Owner will be replacing the wheels. Please provide any further information.
