Owners report engine misfires, rough running, and check engine lights, often around 65,000 miles, with the M264 engine experiencing repeated misfires and shaking. This can lead to reduced power and drivability concerns.
Complaints include loss of power and check engine lights, with one owner noting the car slowed down and wouldn't go. Another issue is headlight condensation causing complete failure, linked to seal problems.
Headlight condensation is a recurring problem, with water inside the housing causing the headlight to stop working. Owners report this makes the vehicle nearly undrivable at night, and dealers often attribute it to impact, though seals may be faulty.
Transmission-related issues include sudden loss of power while driving at city speeds, with multiple incidents reported. A software update is sometimes pending, leaving owners without a fix.
“While driving my vehicle on March 3, 2025 the check engine light came on. Additionally my vehicle began to shake. I was scheduled for a service appointment on March 5, 2025 and told the service department the check engine light need to be addressed. Upon insp…”

The most critical issue is the vehicle completely shutting down while in motion without warning, as reported by multiple owners. This poses a serious safety risk, especially in traffic. Other electrical problems include engine repairs after a motor mount snapped.
Transmission malfunctions causing sudden stalling on highways and main streets are reported, starting as early as 15,000 miles. This recurring issue can leave the car undrivable and dangerous.
Engine problems include check engine lights and limp mode, where the car cannot exceed 9 mph. One incident involved the engine stopping mid-intersection, emitting a strong odor, highlighting potential safety hazards.
The MBUX hard disk drive malfunction can disable backup cameras and other safety features. Owners report that this failure puts safety at risk, and a recall (21V354000) was issued but repairs may be delayed.

Buyer analysis
Mercedes BENZ GLC or Mercedes BENZ A Class: which should you buy?
The GLC has fewer complaints per year (9.6 vs 18.5) and a longer track record, suggesting it may be more reliable in ownership. However, both vehicles have significant issues: the GLC's engine and lighting problems are less severe than the A-Class's tendency to shut down while driving, which is a critical safety concern.
Key differences
- The GLC has 96 complaints over 10 years (9.6/yr) while the A-Class has 74 over 4 years (18.5/yr), indicating the A-Class is more trouble-prone per year.
- The GLC's top issue is engine misfires and rough running, whereas the A-Class's top issue is electrical system failures causing complete shutdowns while driving.
- The GLC has a recall for instrument cluster, while the A-Class has no recalls but has a safety-related back-over prevention complaint.
- Headlight condensation is a unique GLC problem; the A-Class has transmission stalling and MBUX hard drive failures.
- Inspect headlights for moisture or condensation, as seal failures can cause complete headlight failure, making night driving unsafe.
- Check engine history for misfire codes or rough running, especially around 65,000 miles, as the M264 engine is prone to these issues.
- Test drive to ensure the car does not exhibit any sudden loss of power or stalling, as electrical shutdowns have occurred without warning.
- Verify that any recall for back-over prevention (NHTSA 21V354000) has been performed, as the MBUX hard drive can disable safety systems.
Before you buy
- Obtain a vehicle history report and check for any open recalls on the GLC (instrument cluster) and A-Class (back-over prevention).
- Have a mechanic inspect the GLC's headlights for condensation and the engine for misfire codes.
- For the A-Class, perform a thorough electrical system check, including the MBUX system and backup camera functionality.
- Test drive both vehicles at various speeds to feel for transmission hesitation or stalling, especially in the A-Class.
- Review service records for repeated visits related to engine or electrical issues, as both models show patterns of recurring problems.
