An extended warranty is not automatically a trip back to the dealership. If your vehicle carries a manufacturer-backed plan, dealer-backed plan, CarMax plan, or third-party service contract that allows an independent repair shop, bring it to Hillside. We contact the provider, document the failure, and explain the written authorization before you approve work. Coverage and payment still depend on the agreement and the provider's approval.
From Documentation to Approved Repair
Bring the car and whatever plan information you have. Hillside handles the documentation, provider contact, authorization details, and approved repair.
01 Inspect & Document
We identify the failure and document it with measurements and photos from Hillside's free digital inspection, then send the information the administrator requires.
02 Contact the Provider
Hillside contacts the dealer-backed plan, CarMax, or third-party administrator, then explains the authorization, deductible, and any uncovered work.
03 Explain the Decision
The written agreement controls coverage and payment. We tell you what the provider approved and what remains your responsibility before work begins.
04 Repair After Approval
Hillside repairs only after you approve the written plan. The provider contract and Hillside's repair warranty are separate.

The Provider Was New. The Process Wasn't.
A recent extended-warranty repair at Hillside ran into the thousands. The company name was unfamiliar, but the process was familiar: document the failure, call for authorization, explain the approved portion, and take payment by phone when the provider was ready. That experience is why Hillside will contact an unfamiliar administrator instead of dismissing the plan by name alone. The written agreement and provider response still control what is covered.
Plans customers may carry
These are examples of plan names customers may bring in. Hillside is not affiliated with them, and a plan name does not guarantee coverage. If yours is not listed, bring it anyway. We will contact the provider and follow the written authorization process.
Brand names belong to their owners. Hillside is independent and is not affiliated with any warranty provider. We review the written agreement and contact the provider for the authorization required for your repair.
What to bring
- The car, with whatever it's doing (or not doing)
- Your contract, or the pamphlet from the glovebox - the provider's phone number is usually on it
- Your contract or claim number, if it's handy
No paperwork? Bring whatever information you have. The selling dealership, provider phone number, contract or claim number, or a pamphlet from the glovebox can help identify whom to contact. Hillside can help make that first call, but the provider may still require records before authorizing the repair.
What extended warranties typically cover
Plans vary widely. Some address mechanical failures such as engine, transmission, drivetrain, air conditioning, electrical, cooling, steering, or suspension work, while wear items and routine maintenance may be excluded. The written agreement controls, and we compare its terms with the actual repair before you decide.
Do I have to go back to the dealer for covered repairs?
For a factory-warranty repair, check the manufacturer’s requirements before choosing a shop. Routine maintenance at an independent shop does not by itself void a factory warranty, but the manufacturer may deny a claim if improper work caused the damage. Keep the required maintenance records. For a vehicle service contract or mechanical breakdown policy, the written agreement and prior authorization control.
My plan is California "mechanical breakdown insurance" - is that different?
California may regulate a vehicle protection plan as mechanical breakdown insurance rather than a service contract. The policy language, insurer process, and prior-authorization rules control. Hillside can document the problem, contact the provider, and explain the response before you approve work.
How does Hillside's warranty interact with the provider plan?
Hillside's 2-year / 24,000-mile repair warranty is separate and applies only under Hillside's written terms. Replacement engines or supplier-backed components may carry supplier or manufacturer coverage instead. We explain which coverage attaches to the approved work.
Check before you pay out of pocket
Mention your plan when you book, before authorizing repairs. Checking the written terms before work begins can prevent an otherwise covered repair from being handled outside the provider's process. Before you approve the repair, see how Hillside's written repair warranty applies to qualifying parts and labor on this job. Provider coverage and supplier-backed component warranties remain separate.
