Example complaints

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

“My vehicle battery overheated. The dealership was unable to identify the cause. I have since learned there is a battery recall on this make and model, and I believe the recall needs to be expanded to include my vehicle and the overheating was likely caused by the battery failing.”

NHTSA complaint #11767494, filed 2026-09

“This safety recall is over six months old and is still unresolved. I have not felt safe driving the vehicle on the highway because of the possibility of complete power loss. I have been forced to keep paying lease payments on a car I can't drive and the manufacturer has been unresponsive. When I plug the car in to charge, all the lights in the house dim. My other EV does not do this so it must be a serious problem with this vehicle.”

NHTSA complaint #11710665, filed 2026-01

““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. …”

“My 2022 Mercedes-Benz EQB has an unresolved recall (25V487000) issued July 25, 2025 — nearly 10 months ago — with status still listed as remedy not yet available. The recall is classified as URGENT: FIRE RISK WHEN PARKED on NHTSA's website for my specific vehicle. On May 6-7, 2026 I contacted Mercedes customer service three times and received conflicting safety guidance. Agent 1 told me charging above 80% was acceptable and did not advise outdoor parking. Agent 2 (appointed by a manager) told me to restrict charging and park outside immediately, and escalated to buyback team. …”

“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. …”
