Our Work is Guaranteed — So You Can Drive With Confidence
At Wrench Auto Service, we stand behind every repair. We believe that great work speaks for itself, but it should also come with real protection in case something unexpected happens.
That’s why we back most of our repairs with a 2 year / 24,000 mile warranty, giving you added confidence every time you get behind the wheel.
Our team is committed to maintaining high standards for training, quality parts, and customer care, so you can count on dependable results and a repair experience that puts your needs first.
What Our Warranty Covers
Our 2-year or 24,000-mile warranty applies to most qualifying repairs and parts installed by our team. This includes, but is not limited to:
- Brake repair and replacement
- Engine diagnostics and repairs
- Suspension and steering components
- Heating and air conditioning systems
- Electrical system repairs
- Transmission service and repair
- Drive belts, hoses, and cooling system components
If you experience a covered issue during the warranty period, simply contact us. If you’re out of town, we’ll help you find the nearest participating location to handle the repair.
What’s Not Covered
Like all warranties, there are a few limitations. The warranty does not cover:
- Wear-and-tear items like tires, wiper blades, brake pads, or filters unless specifically noted
- Fluids or damage resulting from lack of maintenance
- Repairs made at another shop without prior approval
- Customer-supplied parts or components
- Performance or aftermarket upgrades not installed by Wrench Auto
We’ll always explain what is and isn’t covered before we do any work, and you’ll receive documentation outlining your warranty details.
Nationwide Support, Local Accountability
While your warranty is backed by a national network, you won’t need to jump through hoops. If you ever have a concern, just call us. We’re here to help.
Should you travel or move out of the Middleton area, our team can help you locate a trusted NAPA AutoCare partner to handle any warranty-related needs.
