Is my warranty under threat if i modify my car?

5 July 2016

An engine upgrade, bass-pumping sound system and dropped suspension. The mere thought of these modifications can give you (the driver) and your manufacturer goose bumps, but for completely different reasons.


It can…

Modifying your car, especially to increase performance (by means of a ‘plug-in’ performance microchip for example), or altering it in any way deemed by your manufacturer as adversely impacting performance or reliability, can put you at risk of losing your warranty* or car warranties*.

What can go wrong?

Although you may think it is harmless to add some style and speed to your wheels, doing it yourself or having it done at any unapproved dealership could cause serious damage to your car’s vital components such as your engine or electrical system. Having a radio fitted at an unapproved dealership for example, could lead to a variety of electrical problems which is then not as a result of a defect and is therefore not included in your warranty*.

Check in with your manufacturer

In this case, it is definitely better to be safe than sorry. You’ll find that many manufacturers have their own line of accessories to pick and choose from. Requesting having these fitted when you purchase your car, or fitting them later on - at an approved dealership - will save you the risk of losing your warranty* and your motor happiness.
