How we handle it.
Here’s a real one from this shop. A customer was having trouble starting the car and figured it needed a new battery. When we tested it, the battery was fine. The terminal was badly corroded and the connection was bad. We cleaned the corrosion and the car started right up, with no new battery needed.
That’s why we test before we replace. A noise, a shake or a warning light can come from a few different parts, and the right answer saves money.
You’ll get a report with photos and a plain explanation. Nothing starts until you approve it, and most repairs carry a 3 year, 36,000 mile warranty.
Not every no start needs a battery.
The customer thought they needed a battery. Testing showed a corroded terminal and a bad connection. We cleaned the corrosion, and that was the fix.
