Are Engine Mounts Covered Under Warranty?
Quick answer: Engine mounts (also called motor mounts) are reliably covered under the new-vehicle bumper-to-bumper warranty, typically 3 years/36,000 miles on mainstream brands and 4 years/50,000 miles on European brands. Under the longer 5-year/60,000-mile powertrain warranty, coverage is unreliable: many manufacturers and extended-warranty providers treat mounts as rubber wear items and exclude them. Always get the dealer's answer in writing before authorising a repair.
Bumper-to-Bumper vs Powertrain: Which One Pays?
New cars carry two overlapping warranties, and the difference decides whether your mount is covered. The bumper-to-bumper (basic) warranty covers nearly every component for a shorter period. The powertrain warranty runs longer but only covers the engine, transmission and drivetrain internals, and mounts sit in a grey zone that many booklets push into the wear-item exclusion list.
Bumper-to-Bumper (basic)
Typically 3yr/36k (mainstream) or 4yr/50k (European). Covers nearly all components.
Mounts: usually covered.
Powertrain (extended)
Typically 5yr/60k or longer. Covers engine, transmission and drivetrain internals only.
Mounts: frequently excluded as wear items.
Coverage by Manufacturer
| Brand | Bumper-to-Bumper | Mounts Covered? |
|---|---|---|
| Honda / Acura | 3yr/36k | Covered under B2B; powertrain (5yr/60k) often excludes mounts as wear items |
| Toyota / Lexus | 3yr/36k | Covered under B2B; powertrain mount claims sometimes denied as wear items |
| Ford / Lincoln | 3yr/36k | Covered under B2B; confirm powertrain coverage in writing |
| GM (Chevy, Buick, GMC, Cadillac) | 3yr/36k | Covered under B2B; powertrain coverage of mounts varies |
| Subaru / Mazda / Nissan | 3yr/36k | Covered under B2B; powertrain (5yr/60k) often excludes mounts |
| BMW / Mercedes / Audi | 4yr/50k | Covered within B2B; excluded as wear items once B2B ends |
| Volkswagen | 4yr/50k | Covered within B2B period; check specific model |
| Extended warranties (3rd party) | Varies | Read carefully; many exclude rubber wear items explicitly |
| CPO programs | Varies by OEM | Follow the original/extended terms; mounts may be excluded as wear items |
Warranty terms reflect each brand's standard 2026 US new-vehicle coverage. Coverage language varies by model year and trim, and exclusions for "rubber wear items" are common. Always verify with your dealer or warranty provider before authorising work.
Why a Mount Claim Gets Denied
Classified as a wear item
Rubber and hydraulic mounts degrade with age and heat. Many powertrain and extended-warranty contracts list wear items in the exclusions, and mounts are commonly named there.
Outside the bumper-to-bumper window
If the basic warranty has lapsed (past 3yr/36k or 4yr/50k), the only remaining coverage is the powertrain warranty, which rarely pays for a mount.
Damage attributed to a non-covered cause
Mounts damaged by an accident, aftermarket modifications, fluid leaks, or hard use may be ruled outside the defect-only coverage the warranty provides.
No written pre-authorisation
If you authorise the repair before the warranty administrator approves the claim, you can be left paying out of pocket. Get approval in writing first.
Before You Pay: A 4-Step Warranty Check
- Find your in-service date and current mileage, and check whether you are still inside the bumper-to-bumper window (3yr/36k or 4yr/50k).
- Read the exclusions section of your warranty booklet or service contract and look for "wear items" or "mounts" by name.
- Ask the dealer or administrator to confirm coverage in writing before any work begins.
- If it is not covered, compare the dealer quote against an independent shop. See the cost-saving strategies and the labour-time breakdown.
