🚨 Mercedes EQS 450+ – Ongoing Fault, Dealer Negligence & Warranty.Complaint Ref: 15262538 I’m sharing my experience with the Mercedes EQS 450+, a vehicle I’ve long trusted to deliver premium quality. Unfortunately, this has not been the case. In May 2025, Mercedes Stockport replaced the PTC boost heater under warranty to fix heating/AC issues. However, the problem persists, now causing the vehicle to fail charging and starting and completely DEAD... An independent EV expert has since identified the root cause: during the earlier repair, a wire was improperly adjusted, causing an earth (grounding) fault. This clearly points to negligence by the dealer. To make matters worse: I was surprised to learn my warranty is no longer valid, despite being told it was renewed.Mercedes-Benz STOCKPORT has refused to cover repairs related to this fault, which stems from their own mistake.The rental vehicle has been off-hired today (Pending Invoice for the hire), and also facing a £2,501 repair bill to retrieve my car.Mercedes Head Office has received my complaint but has not responded since 10th May 2025.As a long-time Mercedes customer who has always maintained my vehicles at an authorised dealer UNDER SERVICE PLAN, this treatment is unacceptable. Mercedes-Benz must take responsibility, cover the repairs, and communicate transparently with their customers, especially when faults arise from previous service negligence and ongoing. I need my Vehicle Back as I am left with no vehicle, despite of owning this top end EV EQS 450+ spent in excess of £115,000 and felt like I have been Scammed!!!! #MercedesBenz #EQS450Plus #CustomerServiceFail #WarrantyIssues #EVProblems #Complaint15262538 #DealerNegligence #LuxuryBrandFail
