There has been fire hazard due to manufacturer defect (high voltage battery). It has been under recall since Feb 2025, and till date, no battery replacement has been provided despite of fire hazard. The instructions to keep car outside isn't practical to follow for more than year now! It is electric car whose charger is mounted inside garage. Besides there are car theft risk of parking outside. Manufacturer has been providing unreasonable instructions for long duration of time than resolving the problem, particularly when there is recall for fire hazard even when parked or driving. It is life safety issue for entire family and we cannot continue to use this vehicle

The vehicle experienced multiple electrical and safety-related malfunctions while driving. On several occasions the instrument cluster and vehicle screens suddenly went black while the vehicle was in motion, causing loss of critical driving information such as speed and warnings. In another incident the vehicle displayed a “High Voltage Malfunction” warning while driving and the vehicle shut down shortly after. This resulted in a sudden loss of propulsion and created a dangerous situation on the road. The vehicle has also displayed a “Coolant Too Hot – Stop Vehicle” warning which required replacement of the coolant pump at the dealership. In a separate event the vehicle lost battery charge unexpectedly after indicating a full charge and had to be towed to a charging station. The vehicle is also subject to Safety Recall 26V073 involving the high-voltage battery. According to the recall notice, the battery may fail due to an internal short circuit which could lead to a vehicle fire while parked or driving. The manufacturer currently does not have a repair available and advises owners to limit the battery charge to 80% and park the vehicle outside when not in use due to the potential fire risk. These repeated failures combined with the unresolved safety recall raise serious concerns about the safety and reliability of the vehicle. The issues began around September 2024 and have continued through multiple repair visits into March 2026.

The car is subject to a NHTSA recall 26V073. Mercedes has scheduled warranty repair for December 31, 2026, or more than 9 months from now. Our dealer advises that the scheduled date is just a holding date; there is no assurance that the repair will occur on or before that date. Mercedes has also said in writing that "the battery replacement remedy is not yet available" and that we should complain to NHTSA if Mercedes does not fix this problem in a reasonable time. In the meantime, we are instructed to park the car outside and not to charge it more than 80%. (We've programmed it not to charge over 80%.) Even still, we are at risk that the car will burst into flames, potentially while we are in it, possibly with our grandchildren in the back seat. The other solution Mercedes has is that we should lease a different model at three times the cost of our present lease, thereby shifting the cost of this warranty issue onto us.
