AION AUTO UK and its authorised dealerships are committed to delivering quality vehicles and excellent customer service. However, there may be occasions where the level of service is not as expected.
If issues arise with your AION vehicle, service experience or dealership interaction and you would like to make a complaint, you must first raise this directly with the business. AION AUTO UK is accredited to The Motor Ombudsman’s Motor Industry Codes of Practice for New Cars, and many disputes can be resolved using the business’s own complaints process.
If your complaint remains unresolved after eight weeks, you may be able to escalate this to The Motor Ombudsman for independent review. We offer Alternative Dispute Resolution (ADR) for disputes around faulty cars, rejected vehicles or unsuitable repairs. This page explains how to make a complaint to Nissan Motor (GB) and when The Motor Ombudsman can assist.
Before making a complaint, ensure you have read AION’s complaints policy.
