My issue started in October 2024 - my car was booked in to GH Nissan St Albans with a water ingress issue. The leak was never found by the technicians despite having my car for more that 6 weeks across a 4 month period costing me over ?1300! Eventually we had a friend take a look at the car for us who found the issue, fixed it and tested in 1.5 hours and it has not leaked since. I have taken up with GH but they still maintain they did a good job and fixed it, despite the car leaking every time it rained after they has supposedly fixed it. They refuse to give me a refund or even partial refund as I did not allow them chance to fix it (so 6 weeks is not long enough it seems)! I have now cancelled both my service plans and taken my business elsewhere as I feel they are incompetent and do not trust them to work on my cars on the future. It appears that when you buy a car from them the service is good - aftersales is shameful - so buyer beware.
