Engine never warms up (actually: it cools down) at highway speeds

It sounds like the engine thermostat has failed in an open state. The thermostat regulates the flow of coolant between the radiator and the engine. When the engine needs more heat, it closes and cuts-off flow through the radiator. When the engine needs less heat, it opens and allows flow to the radiator. With the thermostat stuck open, the flow through the radiator is constant and so your engine will have a hard time keeping it's heat. This sort of problem can happen anytime, but it's not until the weather starts cooling that it gets noticed. Colder outside air means more cooling from the radiator. As your your other question, "could any serious damage have been done with the engine below operating temp at highway speeds..." The answer is probably not. You may have lost some fuel economy, but cooling an engine too much shouldn't be too much of a problem. The other extreme, having too much heat, is where engines start to have big problems. In either case, a replacement thermostat is typ

Hello! I have not driven my car for a month and now have this noise. It is a 2016 V Jetta and normally in great shape. The noise is in the background and sounds like something soft is rubbing against something.

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out.

A buddy and I were trying to replace his right front wheel hub, on his 2008 Chevy Impala LTZ. He described the engine size as 3900, I would think that means 3.9 liter, although I didn’t know there is a 3.9, I only know of the 3.8 liter and 3,1 Liter. One of the mounting bolts is so tight that the socket would not keep a grip on the bolt head, no matter how hard we tried to force the socket onto the bolt head. We had tapped on it as best we could with a hammer and metal rod, we heated the area with a torch, no luck. Of course, very little access to this bolt head, so impossible to use an impact
