Trouble starting
Suzuki Grand Vitara will drive in high altitudes, but will not start if it's turned off. Check engine light will also come on in high altitudes, but resolves itself once you're 'off the mountain'...
Auto runs great with temperatures over 20 degrees farenheit. Once the temp goes below 15 degrees, ignition will not turn over.
