1 Engine And Engine Cooling problem

Failure Date: 11/28/2021

My 2019 Toyota 4runner was inhabited by a rat that chewed the wiring harness in at least 3 different areas. The damage occurred between 8pm and 7am. The vehicle started with lights on the dash illuminated. The car was out into drive and was jerking. Reverse had the same result. After inspecting under the hood of the car wires were seen chewed partially and a few completely severed. A rat was seen under the manifold cover. I used an air hose to evict it and had the car towed to dealership. The bill was just under $1000 to repair. I was warned it could have been worse ($6000) if harness needed changing. I was told “I was lucky”. After researching I discovered this is a problem because of soy based wiring. It’s an attractant for rodents.

2 Engine And Engine Cooling problem

Failure Date: 01/14/2021

While driving my 4 runner at about 45 mph, it just stopped working. Engine was still running but it would not go. It was like it was stuck in neutral. I pressed the gas all the way to the floor and nothing. I was stuck in the middle of the road and unable to go. About 30-45 seconds and it began to work again. I took it to newark Toyota and reported the problem but they said since they were unable to duplicate there was nothing they could do. They claimed maybe the floor mat got stuck under the pedal- it is a secure floor mat and I am positive the floor mat was not in the way. I was able to push gas pedal all the way to the floor with no movement of the car. Also I was already driving the car without any issues before it completely stopped working. I am just lucky it didn't happen on an interstate - as I would not have been able to get out of the way of fast moving traffic.
