At vehicle mileage 11,308 with original tires and traveling at highway speed of approximately 70 miles per hour on an interstate highway, the right rear tire suffered a catastrophic, sudden blowout. The loss of control placed the vehicle and its occupants in immediate danger of collision with surrounding highway traffic. The vehicle was towed to Mercedes-Benz of Hilton Head where both rear tires were found to have worn excessively on the inside of the tire due to excessive negative camber built into the factory suspension geometry. Ten days after the blowout, we presented the vehicle to Mercedes-Benz of Asheville for follow-up inspection. The service department informed us that the replacement tires installed at Hilton Head, while of the correct size, were “non-matching of front stock tire” in that they were not run-flat or noise-canceling and we purchased a second set of replacement tires at the factory-specified grade. The underlying cause of the original failure—the rear suspension geometry—was not examined, corrected, or documented at this visit. At vehicle mileage 16,502 and prior to a long-distance road trip, we specifically presented the vehicle to Mercedes-Benz of Asheville to request a dedicated safety inspection of the tires, wheel alignment, and brakes. The service department examined the vehicle and explicitly informed us that the alignment was good and the tires were safe for travel. Approximately 2,864 miles into travel following that clearance, the right rear p

For the 3rd time I took the car to them with the new problem as a very loud explosion sound and a big spark when I was driving on the freeway, witch it call pyrofuse activatin high voltage pyrotechnic disconnect. It basically computer battery electrical failure.

On [XXX] at approximately [XXX] PDT, a 2024 Mercedes-Benz EQS SUV 450+ caught fire at an intersection in Irvine, California. The vehicle was being driven normally. It was NOT charging. It was NOT in a collision. It was stopped at the intersection when the fire began. There was no warning. Four occupants were inside: the driver (age [XXX] ), two minor children (ages [XXX] and [XXX] ), and one elderly passenger (age [XXX] ). All four escaped, but narrowly — the rear child safety locks barely released in time for the children to exit. The vehicle sustained catastrophic cabin burn-through and is a total loss. Smoke and flames appeared to originate from beneath the vehicle, consistent with a thermal event in the under-floor high-voltage lithium-ion battery pack, pending expert investigation. This vehicle is within the population of NHTSA Recall 24V-372 (Mercedes-Benz battery management system software defect, 14,912 2023-2025 EQE/EQS units, including 551 units of the 2024 EQS SUV 450+). Mercedes documented in its Part 573 report that it received field reports of this defect in October 2023 and waited approximately seven months before filing the recall. Mercedes acknowledged fire risk in the EQS platform in NHTSA Recall 24V-115, stating "a risk of fire cannot be ruled out." In February 2026, Recall 26V-073 ordered full battery replacement in EQB vehicles after Mercedes admitted prior software remedies were failed remedies.

The EQS450's delivery was taken from the sonic walnut creek CA dealer on [XXX], the vehicle has ACC and brake assists malfunctioning issues. Phantom braking issues. On [XXX], I was traveling on Interstate at 70-75 mph with no nearby vehicles when the car suddenly braked as if there was a pending collision. It was very scary, it was so violent I thought I had hit something in the road, but it was a clear, dry, sunny day with no road hazards, obstacles or anything else that would have caused it. My wife’s head whipped back and forth, resulting in an enduring headache for her through the rest of the evening. MB Naperville serviced vehicles twice in the past three months , updated software often and again in the next three days, we experienced a sudden and hard stop while driving around 65 mph up a hill. It was a violent and sudden jolting stop. We feel hazardous and untrustworthy to drive the EQS450. MBUSA Case #[XXX] (6/18th) ,CASE [XXX] (6/19th - Opened by Mercedes Benz Naperville IL dealer). Appreciate your help, and options available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
