Problems with 2009 Toyota Highlander WHEELS

This vehicle has an electrical problem, most mechanic shops i took it were not able to find out the nature of the problem. i've changed the battery twice and still experiencing the same problem. at the high way i noticed the that the temperature of the engine gets high, which obliged to drive in a much lower speed with the flashers on which always increases the traffic safety risks.

Our car has 17,000. miles and turns out the tires are bare in spots and the car hydroplaned and skidded and would not hold the road in a light snowstorm. we often skidded right into oncoming traffic. we have driven many suvs over the years -we are 69- and never had a problem. toyota emailed to us that the toyo a20 p245/55r19 open country tires the car came with are not meant for driving in snow. we live in vt and the car was sold to us as an all wheel drive car for driving in snow. i have looked at the internet and others have had the same problem with these tires. i feel there should be a recall on them before someone is killed. my son just purchase a new highlander and i worry his tires are the same. *tr
