Questions to Ask Your Shop
Before Authorizing Repair
- Is diagnostic time included in the estimate or charged separately?
- What is your shop supply charge (percentage or flat fee)?
- Are there core charges on the replacement parts?
- What warranty do you offer on parts and labor?
- What related items should be inspected or replaced while you're in there?
If Complications Arise
- Can I see the failed or damaged component?
- What is the additional time and cost?
- Will you call before proceeding with extra work?
After Repair
- Was a test drive or operational check performed?
- Are there any follow-up checks or re-torques needed?
