2022-2025 Mercedes-Benz EQB Reliability Score: 6.1 out of 10

Reliability Score

6.1 / 10

Reliability score

More owner complaints than similar compact EV SUVs

The class average is 7.0. Based on complaints owners filed with NHTSA about the drive system, battery, charging or electrical system. Electric vehicles are scored against other electric vehicles only, so this score does not compare it with gas or hybrid models. Early evidence: under five years on the road.

Owners filed 35 powertrain complaints. A typical compact EV SUV fleet of this size and age would have drawn about 24.

Scores this low have often eased: the three years after looked about 1.5 points better in the typical case.

Sample complaint excerpts

High-Voltage Battery

Recall 25V050/MBUSA campaign 2025040005 concerns a potential internal battery-cell short circuit and fire risk. I had the BMS software update performed, but Mercedes later issued recall 26V073 because the software remedy was not considered sufficient for all affected vehicles. Recall

I understand that the interim

Thermal Events

[2023] My 2023 Mercedes-Benz EQB is included in the high-voltage battery fire recall (NHTSA campaign 26V073).

Charging System

[2023] Dear NHTSA Safety Team, I am submitting a formal safety-related complaint regarding my 2023 Mercedes-Benz EQB 250, which is currently under an active high-voltage battery recall. The recall imposes significant safety restrictions, including an 80% charging limit, a requirement to park the vehicle outside due to fire risk, and the inability to safely charge the vehicle at home. Additionally, I have
[2023] This complaint documents three deficiencies in Mercedes-Benz's recall response for recalls 25V487 and 26V073. First, the BMS software update applied under 25V050 reduced my vehicle's range by approximately 20% and degraded charging performance without adequate disclosure to owners. Second, Mercedes-Benz delayed notification to U.S. owners after fires occurred in already-remediated vehicles in Euro

Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.

NHTSA recall

High

NHTSA 25V-487 (July 2025) covers 660 EQB 300 and 350 cars from 2022-2023. The screw connection of a bus bar in the high-voltage battery may not meet specification, which can cause a sudden loss of propulsion. Owners are told to park outside, and dealers inspect and replace the battery as necessary, free of charge.

NHTSA recall
