Hello, when it shuts off does it restart right away?

Customer: replied 1 year ago.
Sometimes it will start immediately but other times it will just make a clicking sound, won't start, and keeps flashing the error messages
Expert:  James replied 1 year ago.

Do you have to jump start it to make it start again after it is clicking? Have you checked for codes at all?

Customer: replied 1 year ago.
It will briefly start with a jump but it will immediately shut off again. Once it sits for a couple of hours, it will crank again. You can drive it but then without warning it suddenly starts shutting off again. We replaced the pcm first because the dealer said that it was completely fried and because it wouldn't allow the computer to read the codes.. We drove home from the dealer, but later that night it started shutting off again. Then they replaced the instrument cluster, but it still shuts off. Before replacing the instrument cluster, it said that there may be an issue with the throttle body but once we replaced the cluster that code no longer showed up.

Hmm, do any codes come on when it stalls or do you have a way to test for codes?

I don't have a way to test for codes
Customer: replied 1 year ago.
Not sure what to do at this point.
Expert:  James replied 1 year ago.

From your description it sounds to me like it's a defective alternator. If the alternator has bad diodes it can charge find one day but not charge another. If you are not charging and the warning lights come on. This can be due to having low voltage. When voltage is low the modules shut down to keep the engine running.

Ok. We'll try that
