Warranty & Service Disclaimers

At M&M Auto Techs, formerly M&M Alternators & Batteries, we stand behind our work and want every customer to clearly understand the warranties and limitations that apply to our products and services.

General Repair Warranty

Unless otherwise stated on the repair order or invoice, qualifying labor performed by M&M Auto Techs is covered for:

12 months or 12,000 miles, whichever comes first.

Warranty coverage applies only to the original repair performed and does not cover failures caused by unrelated components, misuse, neglect, accidents, modifications, overheating, external electrical problems, or other conditions outside of our workmanship.

Warranty terms may vary depending on the specific part, service, manufacturer, or repair performed.

Starters & Alternators

Qualifying starters and alternators purchased and installed by M&M Auto Techs include our:

Lifetime Parts & Labor Warranty

This warranty applies to the original purchaser only and is non-transferable.

Warranty coverage is subject to inspection and confirmation that the starter or alternator has failed.

Coverage does not apply when failure is caused by:

• Improper installation or modification
• External electrical problems
• Wiring or connector problems
• Battery-related issues
• Fluid contamination
• Accidents or physical damage
• Misuse, abuse, or neglect
• Failure of another vehicle component

Warranty replacement does not automatically include unrelated repairs, towing, rental vehicles, loss of use, or incidental expenses.

Battery Warranty

Battery warranties vary depending on the battery purchased and the warranty period shown on the customer’s invoice.

Battery warranties are:

Non-transferable and valid only for the original purchaser.

Before a battery is considered defective, M&M Auto Techs may require the battery to be fully charged and tested.

A discharged battery does not automatically qualify as a defective battery.

Warranty coverage does not include failures caused by:

• Leaving lights or accessories on
• Vehicle charging-system problems
• Parasitic electrical draws
• Improper installation
• Improper storage
• Physical damage
• Neglect or misuse
• Normal wear
• External electrical problems

Proof of purchase may be required.

Air Conditioning Diagnostic Services

A/C diagnostic charges cover the testing and inspection performed at the time of service.

Current standard diagnostic pricing may include:

R134a Diagnostic: $40

R1234yf Diagnostic: $90

Diagnostic charges do not guarantee that every leak, intermittent condition, electrical failure, or hidden problem will be identified during the initial inspection.

Some concerns may require additional testing or diagnostic labor.

A/C Recharge Disclaimer

A/C refrigerant recharge services do not include a warranty on the refrigerant itself.

Refrigerant may escape if the vehicle has an existing or developing leak.

Adding refrigerant does not repair the cause of a refrigerant leak.

When applicable, UV dye or UV oil may be added to assist with future leak detection.

Vacuum or suction leak testing can help identify certain leaks but does not guarantee that the system is completely leak-free.

Some leaks may only become visible after the vehicle has been operated.

A/C hoses, electrical components, sensors, modules, actuators, and other related components are not automatically included in an A/C recharge service.

Complimentary Initial Checks

A complimentary initial check is intended to provide a quick preliminary evaluation of the customer’s concern.

It generally does not include:

• Component removal
• Disassembly
• Advanced electrical testing
• Extended diagnostic procedures
• Specialized testing
• In-depth troubleshooting

If additional testing is required, the customer may be offered Basic Testing or Complete Diagnostics before additional work is performed.

Estimates

Unless otherwise stated:

Estimates are valid for 30 days.

An estimate is based on the information and vehicle condition available at the time of inspection.

Additional problems, hidden damage, seized components, broken hardware, previous repairs, modifications, or other conditions may be discovered once repairs begin.

If additional work is recommended, M&M Auto Techs will attempt to obtain customer authorization before proceeding with additional chargeable repairs.

Pricing and parts availability may change after the estimate validity period expires.

Customer-Supplied Parts

M&M Auto Techs does not provide a warranty on customer-supplied parts.

When customer-supplied parts are installed:

• The customer assumes responsibility for the quality and compatibility of the part.
• Additional labor may apply if the supplied part is incorrect or defective.
• Labor required to remove or replace a defective customer-supplied part may be chargeable.
• M&M Auto Techs is not responsible for delays caused by incorrect or defective customer-supplied components.

Rebuilt Customer-Owned Parts

When a customer’s original component is rebuilt and returned to that customer, taxes and warranty treatment may differ from a replacement component supplied from M&M Auto Techs inventory.

Applicable charges will be shown on the final invoice.

Vehicle Testing & Diagnostic Authorization

Customers authorize M&M Auto Techs employees to operate the vehicle when reasonably necessary for diagnosis, verification, repair, inspection, or post-repair testing.

Certain vehicle problems may be intermittent and may not occur during the initial inspection or road test.

A successful test drive does not guarantee that an intermittent condition has been permanently corrected.

Existing or Unrelated Conditions

M&M Auto Techs is not responsible for pre-existing damage, unrelated mechanical problems, cosmetic damage, warning lights, fluid leaks, electrical conditions, or other vehicle concerns that were present before service or are unrelated to the repair performed.

Repairing one component does not guarantee that another related component will not fail in the future.

Warning Lights & Trouble Codes

Clearing diagnostic trouble codes or warning lights does not guarantee that the warning light will remain off.

If the underlying condition remains or another fault develops, the warning light may return.

Additional diagnosis may be required.

Parts Availability & Replacement Components

Replacement parts may be new, remanufactured, rebuilt, or used when specifically disclosed or approved.

Brand and manufacturer availability may vary.

Equivalent replacement parts may be used when the originally quoted brand is unavailable, subject to customer authorization when required.

Special Programs & Rebates

Participation in third-party programs, rebates, financing programs, extended warranties, or assistance programs is subject to the rules and approval requirements of the third-party provider.

M&M Auto Techs cannot guarantee approval, reimbursement amount, processing time, or eligibility.

Any remaining balance not covered by a third-party program is the customer’s responsibility.

Extended Warranty Companies

Coverage through companies such as MaxCare, Endurance, or other vehicle service contract providers is determined by the customer’s individual contract.

Authorization must generally be obtained from the warranty provider before covered repairs are performed.

The customer remains responsible for:

• Deductibles
• Non-covered repairs
• Diagnostic charges not approved by the provider
• Differences between approved labor or parts amounts and the final repair cost
• Maintenance items excluded by the provider

M&M Auto Techs does not control coverage decisions made by third-party warranty companies.

Financing

Financing services may be available through participating third-party providers.

Approval, credit limits, payment terms, interest, fees, and eligibility are determined solely by the financing provider.

M&M Auto Techs does not guarantee financing approval.

Final Sale & Installed Parts

Except where required by law or covered by an applicable warranty, all sales are final.

Installed parts cannot generally be returned once installed.

Special-order electrical parts, programmed components, custom-ordered items, and certain other components may be non-returnable.

Warranty Claims

Before warranty repairs can be authorized, M&M Auto Techs reserves the right to inspect, diagnose, and verify the reported failure.

Customers should contact an M&M Auto Techs location before having a potentially warrantable repair performed elsewhere.

Unauthorized repairs performed by another facility may not qualify for reimbursement.

Proof of purchase and the original repair order may be required.

Important Notice

Warranty coverage applies only to the specific parts and labor identified on the original invoice.

No warranty covers every possible future vehicle failure.

Warranty terms printed on the customer’s repair order or invoice take precedence when they differ from information presented on this page.

Some restrictions may apply.

For questions regarding a warranty, please contact M&M Auto Techs and provide your name, phone number, vehicle information, and original repair order number.
