Service Brakes · reported Apr 14, 2025
The car recently underwent a software update at the dealership for a backup camera issue. When I was driving home on the highway, the car suddenly braked and the seat belts automatically tightened up. This happened 3 additional times on the highway about 5 days later. I had turned off the automatic braking system and it seemed to go away. Then, with the system off, we experienced this again yesterday while on the highway at 70mph. The braking lasts for 1-3 seconds. There is no audible alert or dashboard display. IT renders the car quite unstable as it feels as though the rear brakes are being…

when coming to a stop and applying the break, the transmission stalled. a warning was issued around lane keeping assist and a second warning. Then the transmission light was on. It was not at risk in the moment because no one was behind me and I was coming to a stop sign. If it prevented me from stopping I might have gone through the stop sign It is at the dealership today to service. no warning lamps, messages or other symptoms.

Engine · reported Oct 4, 2023
Twice the vehicle has stalled while driving. I see that there is a recall on my model for a faulty fuel pump which causes this problem, but my dealer claims my vehicle is not part of the recall even though it is having the same issue.
