Drained or Dead Battery in a Chevrolet Tahoe

The most common reason a Chevy won’t start is a dead or drained battery. Your battery provides the initial jolt of electricity to turn over the engine and get it running.

Indications of a dead battery:

  • Silence upon turning the key – no clicking or turnover
  • Accessories not powering on
  • Hard time starting in cold weather

The Fix: Keep jumper cables on hand for a dead battery situation. Jump starting your Chevy Tahoe using another vehicle or jump box can supply enough charge to get it cranked.

You can also clean dirty battery terminals if they prevent a good connection. If problems persist, have your battery tested – it may need recharging if old.

Engine Flooding
