Same with my 2005 burb. Replaced starter in summer 2018. While traveling towing TT had to replace New battery and old alternator in LA in March. Before I left the starter went. When driving through WA last month the vehicle died climbing Lookout Pass. Another battery and alternator. All Delco parts used. At least the last alternator and both batteries were replaced under warranty. Need to check with first mechanic about starter, I returned the broken one to the shop last month.

But now another issue...#7 misfiring and I'm told I need a new engine.
