3 Engine And Engine Cooling problem

Failure Date: 09/12/2023

I went to start the vehicle and it failed to start. I found the fuel pump relay to be badly burned ??. On the 30 pin. The board was melted at the 30 pin spot for the fuel pump relay. I purchased a new relay from napa. I questioned whether they had a new replacement fuel pump. They told me it was not available only through the dealership. My concern was that where the relay was located at there was a possibility of a fire given how badly the relay and board was burned. I replaced the relay and purchased an extra incase this might happen again. To my surprise it happen just days later while I was driving on the expressway. I had to get off the road immediately. Engine died, no power steering. I checked the relay, it was smoking hot. I will have to have the problem resolved. There is no way a relay should ever get hot, let alone that hot. The fuel pump fuse was not effected. Why is the relay not protected from getting so hot. There is definitely a real risk of fire. No one sits in the back seat normally. But, my grandson's. This should not ever happen.

15 Engine And Engine Cooling problem

Failure Date: 03/12/2012

I understand there is a recall to disable and remove the heated windshield solution from the car. This is a feature that cost extra when buying the car and I feel you should repair it, not just remove the feature. Is there any repair instead of removal? if not how do you compensate owners for the loss of functionality of the heated windshield system. I live in the northeast and use it occasionally in the winter.
