2010 Chevrolet Malibu LT 6 Cyl 3.60L
Car wont start after warming up.
The starter and starter solenoid have been changed, alternator and battery/battery terminals are brand new, when the car is cold it starts right up perfectly. after it gets to normal operating temperature and the car is turned off (lets say you get to your destination), if you try to turn it on a few minutes later it will not start, no crank, nothing. lights will turn on, a/c, radio everything electrical works. After letting the car cool down with the hood open (for about 45 minutes) the vehicle starts right up. I have no idea what causes this. please help.
Dirty terminals, old battery, extreme temps - all can lead to the battery not having enough voltage and/or current to start the car. If it drops below a certain voltage during an attempted start (I think it's like 10.5 V) then the computer will not let it start.
