PRIORITY COMPLAINT: MANUFACTURER RECALL OBSTRUCTION & COERCIVE SAFETY WAIVER INDUCEMENT. My vehicle is actively subject to NHTSA Campaign 26V073 for a severe high-voltage battery defect causing an immediate fire hazard while parked or operating. Because the manufacturer has no immediate remedy available, I filed an administrative buyback request due to the extreme danger of driving the car. Mercedes-Benz USA (MBUSA) has formally blocked my safety relief by deceptively citing irrelevant Florida Lemon Laws, despite the vehicle being legally purchased in Maryland and registered/operated continuously in Virginia. Furthermore, MBUSA is actively attempting to obstruct the safety intent of this NHTSA recall by trying to bribe me with a $5,500 cash payment in exchange for signing a mandatory "Waiver of Rights" liability release. This release legally bars me from pursuing future recall remedies or lawsuits if the battery catches fire. MBUSA has explicitly stated in writing that if I refuse to sign this total liability waiver, they will offer zero further assistance, effectively forcing me to continue operating a known, catastrophic fire hazard on public roads. I request that NHTSA’s Office of Defects Investigation (ODI) launch an immediate inquiry into MBUSA for utilizing deceptive out-of-state legal tactics and coercive monetary waivers to suppress safety claims and minimize their financial exposure to Campaign 26V073.

The vehicle is subject to Safety Recall 26V073 (High-Voltage Battery Fire Risk). Since March 2023, at 6,177 miles, the vehicle has experienced recurring powertrain and battery malfunctions. Despite 11 total service visits and 8 specific attempts to repair the battery management system and powertrain modules, the defect remains unresolved. The vehicle currently displays sudden red dashboard warnings stating "Engine will not restart" and "Malfunction" while driving at highway speeds and on sideroads. These incidents cause a sudden loss of confidence in the vehicle's propulsion and power. According to the manufacturer’s recall chronology, these warnings indicate a potential internal battery short circuit, which could lead to a thermal event/fire. Safety is compromised as the vehicle may stall in high-speed traffic, and the manufacturer has directed that the vehicle be parked outside and away from structures due to fire risk. The manufacturer has admitted that previous software "remedies" were failed attempts and that a hardware remedy (battery replacement) is unavailable for at least 9 months (December 2026) . This leaves the driver (owner) in a dangerous, non-conforming vehicle for an unreasonable duration. All malfunctions have been confirmed by authorized dealership service centers (Invoices #685069 and #687727 are attached as references).

My vehicle will not hold a charge. Since buying this car. I have been doing a lot of charging instead of driving. With normal charging, it takes approximately the whole day (24 hours) to have the vehicle charge over 80% and after that, the charge will not hold for a long time. This happens every time.

The car would not start. When I tried to start the car, it said that the charging cable was engaged. The charging cable was not in fact engaged. Even the phone app for the car indicates that the cable is not engaged. There is no way to reset the vehicle or to turn it off and back on. The identical issue occurred in January. We had it towed to the dealer on the weekend. When we returned to get personal items out of the vehicle (1-2 days later, but before the dealer had worked on it) the vehicle started fine and I drove it home. The problem has now recurred.

Single throttle lift-off clunking noise from the side shaft when moving off (audible at the outboard end). The noise is heard once in each instance when changing direction of travel. Note: Sound file in attachment Cause If the complaint is eliminated by experimentally loosening the outboard collar nut (by 1 turn), the problem is due to cracking of the microweld between the wheel bearing inner race and the joint housing of the side shaft. Note: The collar nut must always be replaced after being loosened. See also LI33.20-P-078406 Remedy Coat contact surface of side shaft with wheel bearing with Molykote paint. To do this, proceed as follows: 1. Remove side shafts 2. Clean contact surface A (see image file in attachment "Outer joint housing before") before coating with Molykote, using "spirit" (free of dust and grease) 3. Coat contact surface A (see image file in attachment "Outer joint housing after") with Molykote and leave to dry for "one hour" in removed condition 4.
