Cruise Control problems of the 2016 Toyota RAV4

Passenger front wheel sensor harness was damaged by rodent. Vehicle has 26k miles and Toyota refused to repair the break, and would only replace the entire harness at a cost not covered of $6300. The material change of these parts attract rats. This damaged cause abs, lane departure, blind spot monitoring and cruise control systems to fail. The vehicle was parked in my driveway and I live in a gate community. I called the Toyota customer line and was given the same explanation of the lack of warranty coverage. Case #1710230814.

The cruise control on my 2016 Rav4 le awd with 6 speed automatic transmission is very erratic. At highway speed (60-70 mph) it is fine on a flat road, but at the slightest incline will downshift to fifth, then slam into fourth gear with the engine rpms going up to over 4000. It will then either stay downshifted or constantly shift up and down until I am well over the top of the hill. The dealer said they all do that, so it's normal. I've stopped using the cruise because I'm concerned about possible engine and transmission damage from the harsh shifting and high rpms, but it also is very distracting to the driver which makes it a safety issue. I've complained to "ask Toyota" customer service twice. They just say they'll pass along my complaint to the proper department.
