Mercedes-Benz EQA H243
Weaknesses, engine ratings and buying advice
Engine Overview
The Mercedes-Benz EQA H243 is available with 3 engine variants — from 190 to 292 hp.
Electric drivetrain based on the MFA2 platform (GLA). Battery 66.5 kWh, 11 kW AC charging standard. Reliable drivetrain, battery degradation minimal under normal use.
- !! Farasis Battery Fire Risk (Recall 16136R)
70.5 kWh high-voltage batteries from Farasis (build 12/2021–01/2024) can develop an internal short circuit through cell faults and cause vehicle fires. 51,729 vehicles worldwide affected.
Symptoms: No prior warning. Recall letter from Mercedes. Prior software throttling: charging times +15 min, range -20%. - !! HV Battery Contactor Switches With Delay from 40,000 km
At very low temperatures the main HV battery contactor can switch with a delay. Results in a brief start delay; no safety risk.
Symptoms: Delayed start in frost, brief drivetrain fault message - !! 12V Battery — Discharge During Standstill from 30,000 km
The 12V starter battery is only recharged while driving or during HV charging. After 4–7 days of standing without charging, voltage drops critically. Problem occurs even in vehicles under 2 years old.
Symptoms: App reports critical battery state, power windows no longer operate correctly, vehicle won't start, electrical systems unresponsive

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| AC/DC Charging Interruptions and Fault Messages Frequent charging interruptions independent of charge point or cable. During AC charging the session drops after 5–6% state of charge. On-board charger sometimes needs replacement. Symptoms: Charging stops after a short time, fault message at charge point, charging rate drops below 6 kW. from 20,000 km | High | |
| Drivetrain Fault Message Sporadic warning messages 'Drivetrain fault'. Cause often an MBUX software or HV battery management bug. Symptoms: Drivetrain fault warning, vehicle runs with reduced power; fault disappears after restart. from 30,000 km | Low | |
| Drivetrain Vibrations from 60 km/h EQA vehicles from production from February 2022 show vibrations (droning) from 60 km/h that intensify up to 110 km/h. Cause unclear; workshop often cannot reproduce the issue. Symptoms: Droning or vibration through the floor from 60 km/h, stronger at 100–110 km/h, especially at constant speed from 15,000 km | High | |
| 12V Battery Discharges During Standstill The 12V onboard battery discharges during extended standstill through networked control units. Software update reduces the problem. Symptoms: Vehicle cannot be unlocked/started after several days standing from 20,000 km | Low |
