Making modifications to your car can be an exciting way to enhance its performance or personalise its appearance. However, some mods could put your warranty at risk. A car warranty typically covers repairs or replacements for broken or failed parts. However, if a modification causes direct damage to your vehicle, the warranty for those affected components may no longer apply.

 

Performance Mods That Could Void Your Warranty 

  • Performance Chips/ECU Tuning: Performance chips reprogramme your car’s engine control unit to enhance speed and power. However, altering factory settings could conflict with emission regulations and affect warranty coverage.
  • Performance Exhaust Systems: These systems help engines expel gases more efficiently, improving performance. However, they can disrupt factory settings and cause issues that could void your warranty.
  • Cold Air Intakes: Adding a cold air intake can improve engine power by increasing oxygen supply. While effective, they can lead to warranty complications if they cause engine issues.
  • Nitrous Oxide Systems: Popular in racing, nitrous oxide systems boost power but strain the engine, potentially voiding the warranty.
  • Turbochargers: Turbochargers compress air to increase performance but can cause extensive engine strain, making them a risky modification under a warranty.

 

Visual Mods and Warranty Risks

  • Aftermarket Wheels: Changing rims is a common mod. However, mismatched sizes can damage the suspension.
  • Lowered or Lifted Suspension: Lowering improves aerodynamics, while lifting increases ground clearance. Both can strain suspension components and void warranties.
  • Body Kits: These include spoilers, splitters and sills for a sportier look. While they rarely impact on mechanical components, dealers or insurers might flag them if issues arise.
  • Aftermarket Lighting: Replacing standard lights with LED or HID kits can improve aesthetics, but may lead to electrical complications.

 

What to Consider Before Modifying Your Car 

  • Consult an Expert: Always ask your dealer or insurer how specific mods could affect your warranty.
  • Extended Warranty Impacts: If you have an extended warranty, ensure your mods won’t void it.
  • Resale Value: Modifications can impact your car’s resale value positively or negatively, so choose carefully.

 

The Safe Route

While car modifications can be fun and functional, they come with risks. Manufacturer-approved upgrades are the safest option, while performance and visual mods require caution.

Always check with your dealer or insurer before making any changes to ensure your warranty stays intact.
