I just had a 4 wheel alignment. I believe there may be an issue with the steering column or electric power steering

Drove fine to work, went out for lunch noticed battery light first and then all of a sudden my temperature gauge went into the red zone and a red light came on. Checked the coolant, it was low. so I added some coolant and car seemed happy for the few minutes the warning lights went off. Then back on they went. I pulled over and had it towed... I have replaced the reservoir tank already, so it shouldn't be a radiator issue. I just most recently had some ca-smog things replaced. Wondering how much money to fix this time and/or is it time to give up?

A long nail runined my tire so I put one on to replace it on the passenger rear side. Do I need to replace the other back tire?

Think it might be the expansion valve. How much to replace it?

All for wheels lock-up with out using pedle. Like bring the car to a stop . And turning the key off and on makes them release ?

My car only has about 80K miles on it and my air compressor is leaking oil. Can I just have my compressor fixed by putting new gaskets and/or whatever else is needed or do I need to purchase a new/remanufactured part?
