Chevrolet Colorado intermittent no-start issue despite functioning electrical components on Chevrolet Colorado

Some Chevrolet Colorado owners report experiencing intermittent no-start issues despite having functioning electrical components. Common reasons for this problem include a dead battery, alternator issues, and a failed starter. Additionally, some owners have reported specific intermittent electrical problems in the 2023 Colorado LT, such as power windows not always working from the driver door switch and complete electrical failures while driving on the interstate. Symptoms of these intermittent failures may include cruise control disengaging and experiencing total electrical failure after stopping for gas. Troubleshooting efforts, such as pulling starter and run/crank relays in the underhood fuse box, may provide temporary relief. Other conditions indicating potential underlying issues include the air conditioning blowing hot air, fluctuating engine oil pressure gauge readings, engine misfires, and illuminated warning lamps on the Driver Information Center. It is advisable for owners to check the battery health, inspect the alternator and starter, and conduct thorough diagnostics to address any abnormal symptoms or warning messages.
