Tesla Model Y Chronic Trunk Water Ingress And Service Failure

I am writing to report a critical manufacturing defect and a subsequent service failure regarding my 2025 Tesla Model Y Juniper (VIN: XP7YGCFS9SB675017). Despite being a brand-new refresh model with only 15,000 km, the vehicle has a serious water ingress problem in the liftgate assembly. I first noticed this issue on 18.02.2026, when water was detected inside the trunk area of the vehicle. On 27 February 2026, Tesla Mobile Service in Kayseri examined the vehicle but failed to identify the source of the leak. I was then directed to an authorized body shop in Kayseri, İncirioğlu, which initially refused service and later proceeded with what they themselves described as an “experimental insulation” process, without first determining the exact breach point of the water ingress. Instead of following official Tesla service bulletins and factory procedures, they repeatedly disassembled and reassembled the trunk and liftgate components, essentially applying a trial-and-error approach on a new vehicle that is still under factory warranty. As a result of these interventions, my 2025 Model Y has been subjected to multiple unplanned body and trim operations without a clear root-cause analysis or confirmation that the leak is definitively resolved. I do not accept this experimental, trial-and-error method as an appropriate solution for a new car under warranty, nor do I find it compatible with Tesla’s claimed global quality and service standards. In this context, I demand either a replacement with a defect-free equivalent vehicle, in line with consumer protection rights, or a definitive repair performed strictly according to Tesla’s global factory standards and official procedures. If repair is chosen, I expect Tesla to cover all related logistical costs, including towing and a loaner vehicle for the entire repair period, and to compensate me for the commercial loss and depreciation in value caused by these extensive interventions on a nearly new vehicle. Additionally, I expect Tesla Global to intervene directly and ensure that its local representatives in Turkey, including the Kayseri İncirioğlu service, act in full compliance with the brand’s international quality and service standards. I request that this situation be urgently reviewed and that a clear, written solution proposal be provided that fully protects my rights as a consumer and restores my trust in the Tesla brand.
