Dead Battery in a Chevrolet Suburban

Image Credit: MechanicAnswer.com

The most common cause a Chevrolet won’t start is a dead or weak battery. Your battery supplies the initial jolt of electricity to turn over the engine and get it running.

Signs of a dead battery:

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

How to Fix It: Keep jumper cables available for a dead battery situation. Jump starting your Chevy Suburban using another vehicle or jump box can supply enough charge to get it started.

You can also clean corroded battery terminals that are blocking a good connection. If problems continue, have your battery tested – it may need replacing if worn out.
