How to Maintain Your Car if You Have an Extended Warranty

If you have an extended warranty, you’ll know all about the peace of mind you now have for covered breakdown repair costs. However, what you may not know is that there are some maintenance requirements you’ll need to follow to keep your warranty valid and save any claims you make from being rejected and leaving you with unexpected repair costs.  

This guide outlines the key steps you should follow to maintain your car and ensure compliance with your extended warranty terms. 

1. Understand Your Warranty’s Maintenance Requirements

Every extended warranty has specific conditions outlined in the policy terms and conditions. Make sure you read this carefully to identify your obligations. Common requirements include: 

• Following the manufacturer’s recommended maintenance schedule. For example, oil changes, tyre rotations, fluid checks and the like. See below for some guidelines on this. 

• Using authorised service centres or certified mechanics for services, repairs and maintenance. 

• Stick to the manufacturer’s recommended service schedule and keep detailed records of all services performed. 

Tip: Contact the warranty provider if any terms are not clear. Misinterpreting the requirements could jeopardise your coverage. 

2. Follow the Manufacturer’s Maintenance Schedule

Most extended warranties require you to follow the maintenance schedule in your vehicle’s owner’s manual. This typically includes: 

Tyre Rotations: Every 5,000–7,000 miles, using a cross-rotation pattern to ensure even wear. 

Fluid Checks and Replacements:  

• Brake fluid: Manufacturers suggest varying intervals but, generally the recommendation is at least every two years.  
• Coolant: The general recommendation is to change the coolant every two years, but OAT fluids can last up to five years. 
• Oil change: Changes are recommended between 5,000 to 7,500 miles or annually, depending on which comes first. Refer to your vehicle owner’s manual for guidance.  
• Power steering fluid: It’s advisable to change this every 24,000 miles or 2 years, although mechanics should check it when you’re having a service.   
• Transmission fluid: Most manufacturers recommend a flush and transmission fluid change every 30,000 miles or every 2 years. 
  

Filter Replacements:

• Air filter: Under typical driving conditions in the UK, it’s generally recommended to replace your air filter every 10,000 to 15,000 miles, or every 12 months 
• Cabin filter: The usual recommendation is every 15,000 to 30,000 miles – which is about once a year for daily commuting drivers, and every two years for infrequent drivers. 
• Fuel filter: It’s generally recommended that you replace your fuel filter every 30,000 to 50,000 miles, or every 2 to 3 years. 
• Tip: Check your owner’s manual or consult your dealership to confirm the schedule for your specific vehicle make and model. 

3. Use Authorised Service Centres

Most extended warranties insist that you service your vehicle at an authorised service centre and that any maintenance or repairs are carried out by authorised providers and qualified mechanics. This ensures that any work done meets the manufacturer’s standards.  

When booking services: 

• Verify that the garage is an authorised service centre and that you will received a VAT invoice for the work carried out. 

• Ensure the mechanics are qualified and use genuine or manufacturer-approved parts. 

• Do not carry out any DIY repairs, as these may void your warranty. 

Tip: Keep a list of approved service centres in your area for convenience. 

4. Keep Detailed Service & Maintenance Records

Documentation is critical to make sure your vehicle is compliant with your warranty conditions. Keep a comprehensive record of all services, maintenance and repairs, including: 

• Receipts and invoices from service centres. 

• Dates and mileage for each service. 

• Details of the work performed and parts replaced. 

Tip: Store these records in a safe place and consider keeping a logbook in your car for easy reference. Warranty providers may request these records when processing any claims you make. 

5. Address Issues Promptly

If you notice any issues with your car, such as unusual noises, warning lights, or performance changes, address them immediately. Delaying repairs can lead to further damage, which may not be covered if the warranty provider determines it resulted from neglect.  

• Book an appointment with an authorised service centre as soon as possible. 

• Report the issue to your warranty provider if it’s potentially covered. 

Tip: Don’t leave it until another time to investigate warning lights or other issues to save money. It could cost you much more in a declined breakdown claim.   

6. Avoid Modifications

Extended warranties generally prohibit modifications that alter your car’s performance or structure, such as aftermarket parts, tuning, or cosmetic changes. These can void your warranty, even if unrelated to a claim. If you’re considering modifications: 

• Check with your warranty provider beforehand. 

• Stick to manufacturer-approved accessories or upgrades. 

Tip: Check your policy document or call your warranty provider if you’re considering any modifications. 

7. Schedule Regular Inspections

Even if your car seems fine, regular inspections can help to identify any potential issues before they become serious. Many warranties require periodic check-ups to ensure the vehicle remains in good condition.  

Tip: Even if your mileage is low, schedule a service inspection at least annually or as specified in your warranty terms. 

Conclusion 

Maintaining your car to meet extended warranty requirements is vital when it comes to making sure your claim won’t be declined. By following the manufacturer’s service and maintenance schedule you can protect your warranty coverage and avoid costly surprises.  

Always refer to your warranty agreement for specific terms, and when in doubt, consult your provider for guidance. Proper care not only ensures compliance but also keeps your car running smoothly for years to come.
