Hillmuth Auto Care 36/36 Guarantee

At Hillmuth Auto Care, we want you to know that we have your best interest in mind. We don’t practice the hard sales approach, and don’t recommend repairs we think are unnecessary. That’s one of the reasons our customers give us glowing reviews and keep bringing their vehicles to Hillmuth year after year—and we want to keep it that way. While other shops may only offer a 12, month/12,000 mile warranty that covers your repair for a year, Hillmuth Auto Care offers a 36-month / 36,000-mile Nationwide Warranty* We’re dedicated to making sure the car repairs we perform at our shop are done the right way, every time.

Our Nationwide Warranty

We are confident in the expertise of our technicians and the quality of our services, which is why we offer a 36-month / 36,000-mile Nationwide Warranty* on parts and labor from the original repair date and mileage. Odometer reading and date of service will be used to determine eligibility. If an odometer reading and/or service date is not listed, this warranty is void. Hillmuth Auto Care will not warranty any parts of the vehicle that was not repaired at one of our locations, regardless how damaged. Other exceptions may apply.

Warranty Transferability

The 36-month / 36,000-mile standard warranty is transferable and can only be honored at one of the Hillmuth Auto Care locations in which it the original auto service was performed. The Nationwide warranty is voided upon transfer of vehicle ownership.

Nationwide Warranty*

  • If you’re traveling, and you’re more than 100 miles from one of the Hillmuth Auto Care locations, call the the Hillmuth Auto Care location where the previous service was repaired to start the warranty process. Hillmuth Auto Care needs to be contacted prior to any work being performed. All calls will be answered Monday thru Friday, 7:30 am – 6:00pm Eastern Standard Time.

  • The date of original repair and odometer reading will be used to determine eligibility. Reimbursement is limited to covering up to the original dollar amount charged for the part and labor/tax associated with part as listed on the original service ticket.
  • Reimbursement shall not exceed original cost of installation. If the warranty repair costs are less than the original service ticket, the lesser amount will be reimbursed.
