Cadillac XT5 engine won't start with warning light, suspected computer issue after 11 days in service on Cadillac XT5

Some Cadillac XT5 owners report experiencing starting issues accompanied by warning lights, particularly after 11 days in service. These problems may stem from various factors, including a dead key fob battery, a weak or dead 12v battery, corrosion on battery terminals, or a faulty alternator. Additionally, some owners note that a clogged fuel filter, damaged starter, blown fuse, empty gas tank, or immobilizer error could also prevent the engine from starting. If the engine cranks slowly or not at all, it is often linked to a weak battery, and conducting a battery voltage test is advisable. Owners have also found that intermittent connections between the battery and ground or starter can lead to starting difficulties, especially in colder temperatures. If warning lights persist, it is recommended that owners seek inspection from a qualified mechanic to diagnose potential computer system issues or related components for necessary repairs.
