A couple of weeks ago I couldn't get the engine to turn over. Jumped it and let it run for about 45 minutes. Took it in to have maintenance done on it. They found nothing wrong with the battery (which is 3 yrs. old Diehard).

Today I stopped at the store, when I tried to leave it would not turn over.

HELP

Yes - lights come on and dims when trying to start, also the tailgate dislodges. The CD player sounds like it is searching the disc, however the unit is not on.

Would a jump get it started ?
if so do a battery draw test and also drain test
check charging system and alternator diode function
smart battery tester should pick up any faults
old way of checking battery will not show the fault
