Unless you’re in extremely cold weather, warming up engines is usually not required, and hasn’t been for decades.

Driving away right after start-up and driving easy for the first few minutes is all that’s needed (except for cold winter climates!). Its possible that your Mitsubishi either doesn’t have a thermostat, or it is stuck open.

In mild or warm weather, most vehicles’ temperature gauge will climb up to close to the halfway point within a few minutes of driving. That is something to look for that may provide a helpful clue. It also possible that your vehicle has a fuel control issue that is preventing it from delivering the correct amount of fuel into the cylinders. This can be the result of a faulty sensor, fuel injectors, fuel pressure regulator, or a vacuum leak.

Hello. I recently had transmission issues with my truck. I was getting noises from under it as if marbles were rolling around in the torque converter, and soon after my vehicle had problems shifting. However the main thing worrying me currently is that today I tried to at least start my vehicle and it no longer does. Could a faulty transmission or torque converter cause an engine failure?
