NHTSA Complaint #11457462 — 2022 HONDA RIDGELINE

I bought a new 2022 Honda Ridgeline RTL-E February 2022. Drove it 100 miles and was driving down the road 40 mph with no one in front or behind. The brake warning light came on and the ABS locked up. The dash lit up and said "Collision Mitigation System Problem". The same CMS failure happened a half dozen times until I got it home. I took it to the dealership the next morning and on a test drive, the same thing happened to their service manager after resetting the system. They said the vehicle was not safe to drive. They kept it and are trying to get a radar sending unit but there are none. They have had the truck for almost 4 weeks. I have since read about this same failure mode going back to the 2017 model year.
