2020 MERCEDES-BENZ GLS 450 Complaints
AMENDMENT TO ACTIVE CASE 11723015. CRITICAL AIRBAG & SAFETY DEFECTS. This files a safety defect amendment to open case 11723015. Diagnostic scans confirm central data bus network collapse on VIN [XXX] has migrated into safety-critical occupant restraint and visibility modules, violating 49 U.S.C. § 30118. I. AIRBAG & RESTRAINT HAZARDS Scans from [XXX], document active faults: DTC U042782: "Implausible data received from Electronic Ignition Lock." The SRS module receives corrupted data from the failed ignition gateway, creating risk of airbag non-deployment. DTC B007A13: Passenger seatbelt pre-tensioner open circuit; occupants are unprotected against crash displacement. DTC B11FA4B: Active "Overtemperature" faults in heating elements indicate localized thermal short-circuit risk. II. HARDWARE DECAY Physical teardown confirmed structural oxidation on the central gateway motherboard and corroded connector pins. Modular swaps failed; network lock code U016887 returned within 8 months. Raw dealer records are available for federal inspection.

2021 MERCEDES-BENZ GLE 580 Complaints
My Mercedes GLE 580 experienced a complete failure of the 48V battery system due to the exact defect outlined in NHTSA Recall Campaign 24V207 (defective 48V ground connection causing high resistance and fire risk). The official status for my VIN shows 'Recall Incomplete.' The vehicle is currently at Mercedes-Benz of Barrington. The dealership is actively refusing to remedy this safety recall under warranty and is attempting to charge me $5,313 out of pocket for the battery replacement. Furthermore, the dealership refuses to submit the correct diagnostic error code (B183371) to my extended warranty provider to block coverage. My family has been left completely stranded without transportation for 7 days, and the manufacturer refuses to provide a loaner vehicle while the vehicle is unsafe to drive due to this fire hazard recall.;
2021 MERCEDES-BENZ GLS450 Complaints
Both rear wheels on this vehicle have developed cracks which leads to tire pressure loss. Apparently, this is a common issue with Mercedes' heavier vehicles like the GLS and S series sedans. To be clear, I did not hit anything. I did not do any unusual driving. Both rear tires are fine. While you expect that certain components on a vehicle will have problems, it is also reasonable to expect that wheels will not crack prematuraly. Mercedes is aware of the problems. They were named in a class action lawsuit that was dismissed because cars were out of warranty. Warranty or no warranty, this is a major safety issue as a loss in tire pressure can be catastrophic.;
2021 MERCEDES-BENZ GLS580 Complaints
The vehicle suffered a sudden, catastrophic 48V mild-hybrid electrical power supply breakdown and complete system failure while traveling at highway speeds during a cross-country move. The sudden failure forced an emergency lane change into an isolation zone just off the highway. The sudden failure left the cabin completely powerless with no operational safety systems, hazard lights, or air conditioning in extreme 100+ degree heat. This roadside isolation created an immediate physical hazard and directly inflicted acute heat exhaustion and severe dehydration, requiring a subsequent emergency clinical medical evaluation on July 5 for lingering environmental exposure symptoms. Subsequent forensic diagnostics performed at an authorized secondary dealership (Mercedes-Benz of North Scottsdale) captured digital video evidence of active, high-voltage 48V electrical arcing across a completely loose, un-torqued main grounding network connection left by a prior repair facility (Mercedes-Benz of Syracuse) during a major warranty engine removal repair just 7 days prior. Secondary dealer diagnostics officially logged this internal structural failure under factory tracking as Damage Code 5482G388. The loose connection created an active, immediate thermal and fire hazard capable of igniting nearby fuel or fluid lines. The original repairing facility deflected liability, claiming the high-voltage ground studs 'loosen due to many reasons' on an asset with no prior electrical faults. This creates a severe ongoing fire, thermal, and crash risk for this model year's 48V electrical system architecture.;
