Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.

NHTSA currently has 15 investigation files overlapping the 2024 GLS 450. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

20260212CrashFORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

The 2024 Mercedes-Benz GLS 450 exhibits a critical "Spatial Mapping Offset" defect within the MBUX 360-degree camera interface and the Active Brake Assist (ABA) logic. Specifically, the digital rendering of physical obstacles on the dashboard display is offset by approximately 0.5 feet (6 inches). This creates a "false clear" condition where the driver is visually signaled that an obstacle has been cleared while the vehicle’s chassis is still in a strike position. On September 27, 2025, this defect resulted in a collision with a stationary post. Despite the system’s Parking Control Module identifying the object (recorded as "Orange/Indented" in dealer Repair Order #731706), the system failed to escalate to a Red Triangle alert or initiate autonomous braking. Furthermore, the vehicle’s sensing suite is demonstrably unstable, exhibiting "Phantom Alerts" (detecting non-existent obstacles) and total Augmented Reality (AR) camera blackouts in direct sunlight—a failure the manufactur

On [XXX], my wife and I were driving our 2023 Mercedes-Benz GLS 450 when I pulled over after sensing vibration on the highway. Upon inspection, all four tires were found to be severely worn, with the right rear tire completely bald and showing exposed steel belts. I have attached photos of the tires. The vehicle had been serviced at Mercedes-Benz of Wesley Chapel, FL at 10,000 miles in January 2025, and the dealer noted the rear tires were at 3–4/32" tread depth. Despite this, we were not warned that the tires were unsafe. The dealership did not contact us, did not send photos, and did not recommend immediate replacement — even though they did follow that protocol on our other vehicle (a GLE 350) serviced the same day. This inconsistency in communication led us to unknowingly drive 4,000 miles — including 60 miles at highway speed — on dangerously unsafe tires. The dealership has admitted the tread depth was low at the time of service but is attempting to shift responsibility

20250531FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Over the past 14 months, the emergency breaking system has gone off approximately 25 times during non-emergency situations. Most of the incidents have been when no other vehicles or impediments are anywhere close by. This has created a very significantly unsafe and ongoing situation for my family which so far are being ignored by Mercedes Benz.

20250109ELECTRICAL SYSTEM

Head-up display unit inoperable on multiple occasions over a span of few months during the first year of ownership. Display panel occasionally went blank, including while driving.

20241004STRUCTURE:BODY

The glass panel between the windshield and the sunroof spontaneously shattered. I wasn't aware of this and had just noticed increased wind noise while driving for a few weeks until I noticed that it was due to shattered glass panel. It is cracked almost all around and somewhat dislocated. Upon close inspection in can be seen that cracks run throughout the glass panel. There is no single point of impact of a possible foreign object, so I can rule out the possibility of something hitting it with high confidence. I took it to the dealership but they refused responsibility under manufacturer warranty, claiming it must have been an object hitting it and quoted $3,815.10 for repair. I have detailed pictures showing no impact marks.

20240909ELECTRICAL SYSTEM

The contact owns a 2024 Mercedes-Benz GLS450. The contact stated while the vehicle was idling, the vehicle shut off with several unknown warning lights illuminated. The contact also stated that a message to exit the vehicle was displayed. Due to the failure, the vehicle was towed to the dealer on four separate occasions. The vehicle was towed to the dealer and the contact was informed that the failure was related to the battery. The battery was either recharged or replaced while at the dealer; however, the failure returned soon after repair. The vehicle was not repaired and remained with the dealer. The manufacturer was notified of the failure but offered no assistance. The failure mileage was unknown.
