NHTSA Complaint #11548228 — 2022 CHEVROLET TAHOE

The safety issues with this vehicle all seem to be related to the vehicle Park Assist and cross track functions. The dealer has attempted on several occasions to fix the vehicle without success.There is usually no warning when theses functions are not working properly except sometimes there is flashing spot on the screen instead of warnings. While the dealer has not been able to duplicate some of the issues, they have witnessed the flashing screen and I have provided videos of the dashboard when in failure mode. While I know one can't rely solely on the park assistance features, the inconsistency of this system poses great risk for pedestrians and property damage. The dealer stated that the manufacturer of my car is aware of this problem but does not have a solution. There have been no accidents to date so the issue is on-going. Description of problems: 1-The Park Assist system often does not detect large vehicles, walls, trees, etc. that are within inches of my vehicle. On other occasions the alert system works fine. I back the Tahoe into our garage at least once every day. This vehicle does not perform consistently under the same circumstances. Some days the Park Assist function works well and other days it seems to sense nothing behind me. 2- A flashing white dot sometimes appears in the center of the camera screen when backing up. In most cases the Park Assist is not functioning when the flashing dot appears. (A video of this condition was provided to the dealer.) 3-My car is equipped with 2 types of warning signals indicating when there is a potential collision: a.Option 1: Vibrating driver’s seat b.Option 2: Audible beeps I prefer audible beeps and always select Option 2. My truck frequently changes the mode to vibrating seat. This is very disconcerting and annoying when the truck suddenly switches to vibrations unexpectedly. I do not like the vibrating seat and expect the vehicle to retain the setting I choose.
