Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

““My 2023 Mercedes-Benz EQB 350 is subject to NHTSA recall 26V073 involving a high-voltage battery defect that may cause a fire. The manufacturer has instructed me to limit charging to 80% and to park the vehicle outside due to fire risk. This significantly reduces the vehicle’s usable range and creates safety concerns. Due to this 80% charging limitation, the vehicle no longer provides sufficient range for my daily commute and cannot be reliably used for its intended purpose. …”

“I am reporting a serious safety hazard involving my Mercedes‑Benz EQB 350. Drive only 1.5 year, Jan 6, 2026, the vehicle suffered an electronic failure at LaGuardia Airport and became completely inoperable. It could not shift into Drive, Reverse, or Neutral and had to be towed to Mercedes‑Benz of Huntington for warranty repair. During service, the dealer performed a wheel alignment on Jan 16, 2026 without my authorization. I had previously declined alignment recommendations because my factory alignment was excellent and my tires were wearing evenly. …”

“I am reporting a substantial safety defect regarding the high-voltage battery system in my 2023 Mercedes-Benz EQB 350. The vehicle suffers from a 50% loss of advertised range (real-world range of ~95 miles vs. 210 miles advertised) and severe DC fast-charging failures. My VIN is subject to NHTSA Recalls 25V050000 and 25V894 for high-voltage battery fire risk. Per the manufacturer's safety instructions, I have been told not to charge the vehicle above 80%, which further degrades the vehicle’s utility. Additionally, the vehicle is subject to Recall 25V487000 for sudden loss of drive power. …”
