   When I'm driving my truck, usually when I have come to a stop on an incline, the parking/emergency brake will engage on its own. For example, most recently I was pulling out of a driveway with an incline. I was stopped at the bottom of the driveway to wait for the roadway to clear before I pulled out. When I hit the gas to go, the rear wheels skidded and the truck came to a stop in the oncoming traffic lane. I looked at the dashboard and saw that the parking brake symbol was…

   There is a warning on my dash when the vehicle is placed in reverse: reverse brake assist not available see manual. This concern has a tsb attached to it. My concern is that given the safety nature of this concern affecting f150s and ford mustangs; this should be covered by the manufacturer and not the consumer. Ford will repair, however, invoice the customer for the cost which i do not agree with. I am not certain how many vehicles are affected or if it rises to the…

   My Ford F-150 is subject to Manufacturer Recall Number23S65/NHTSA Recall Number23V896. I asked for the repair multiple times, but the dealership repeatedly told me that the parts were on backorder. The hub bolt on my right rear tire cracked and the truck was making a high pitched sound. I took it to the dealer and they said the bolt was cracked and driving it in that condition is dangerous. The truck is not safe to drive, but the parts remain on backorder indefinitely.

However, when I look up my VIN under Ford, that did not show, and thus, we did not address this earlier when that should have…
