I have an issue with my Vauxhall 2025 Grandland GSE MHEV. The vehicle is less than a year old. After a few months of faultless motoring, the hybrid assist now fails to engage at all. It is as if the car has reverted to being a petrol-only engine. This is extremely frustrating as I feel I have paid for a vehicle that does not work. I have taken the vehicle into a Vauxhall dealership, and I have consulted the Vauxhall dealership where I purchased the vehicle from. Both the service centre and the original sales staff have drawn a blank. The service centre has been in contact with Vauxhall, after diagnostic reports have been shared with them, but there is still no update. Quite by accident, when switching on the windscreen de-mister (which turns on the air conditioning), the blue speed lights lit up, and hybrid assist was engaged, although intermittently. Since then, I have "played" with the AC buttons, both the windscreen de-mister and directly from the infotainment panel, and this seems to wake up the hybrid assist, but not consistently. I have shared this experience with the service centre, who told me they would feed this experience back to Vauxhall while we await their next steps. This experience should warn potential buyers away from the MHEV, as, so far, Vauxhall are clueless as to how to proceed. Obviously the vehicle is under its 3 year warranty still, and I have initiated interactions with the service centre inside 12 months from initial vehicle registration. Does anyone know how this matter can be resolved, or has anyone had this same experience? Should I be initiating requests for money-back?
