general problems of the 2018 Toyota Sequoia

I purchased this vehicle new from mark miller Toyota on fri Dec 29th, left the dealership at 12:10pm with 39 miles on it. Ran a few errands and showed my friends, we went to leave after eating some food and at 45 miles in my odo I got 2 error messages. "blind spot monitor malfuction, visit your dealer" and "rear cross traffic alert malfunction, visit your dealer". I had only put 6 miles on this and I contacted the dealership right away at 6:47 pm and was told that the service dept wouldn't hang around for me to get there in 10 mins or less and that I could bring it in another day or to any dealership. Light has come on 2 more times since, the 3rd time total, I drove it to a different dealership(that's closer to me) but they had no one available to look at it. The service lady did see it but all she did was make an appt for me for wed Jan 3rd to have it look at. I've talked to another gentleman through a forum and he had this same problem and sent me the name of his investigator at your offices. His name is ajit alkondon.

The vehicle has a malfunction on the rear cross traffic, blind spot monitor and possible adaptive cruise control - at only 30 miles.

Issue: safety features failing at less than 500 miles problem statement: at less than 500 miles the safety sensors ( collision prevention, cruise control adaptable speed, rear cross traffic, blind spot monitor ) are failing repeatedly. Dealer has contacted Toyota for support. No eta at present.
