Mercedes BENZ A Class
The Mercedes-Benz A-Class is a smaller, newer entry-level luxury car, with only 4 years of complaint data. It has just 80 complaints total, or about 20 per year, and no recalls on record.

Owners report check engine lights, shaking, repeated misfires, and rough running, sometimes around 65,000 miles. In some cases, the car loses power or enters limp mode, which can leave you vulnerable in traffic.
Complaints include moisture or condensation inside headlights that causes them to stop working, and one owner noted their vehicle had the same defect as a recall that didn't cover their car. This can affect visibility and safety, especially at night.
Drivers describe sudden, intermittent drops into limp home mode and loss of motive power, even at low speeds. These events create dangerous speed differences with surrounding traffic and may require expensive diagnostics.
Some reports are alarming: a vehicle caught fire while driving, and another had the rear window shatter spontaneously while backing out of a driveway. These are rare but serious and can be costly to repair.
“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…”

Owners report the car completely shutting down while in motion with no warning, sometimes in intersections, and emitting a strong smell. Another had major engine repairs after a motor mount snapped on the freeway, followed by ongoing issues.
A recurring transmission malfunction caused the car to suddenly stall and shift at speeds between 15,000 and 75,000 miles. Another owner reported multiple safety concerns shortly after purchase, suggesting early quality problems.
Check engine lights and limp mode are reported, with one car unable to exceed 9 mph after pulling onto the highway. This can be dangerous if it happens in fast-moving traffic.
One owner described the car shutting off and shifting into Neutral at a red light, with all warning lights on and a message to restart. This kind of sudden stall can leave you stranded or cause a rear-end collision.
“While driving my lease vehicle on two separate days, it completely shut down while in motion with no prior warning. The first incident occurred while crossing a MAX train intersection in downtown Portland. The engine stopped mid intersection, emitted a strong…”

Buyer analysis
Mercedes BENZ GLC or Mercedes BENZ A Class: which should you buy?
The Mercedes-Benz A-Class has far fewer complaints per year (about 20) compared to the GLC (about 129), and it has no recalls on record. However, the A-Class complaints often describe sudden shutdowns and transmission failures, while the GLC has a broader range of issues including engine, electrical, and fire risks. In practice, the A-Class may have fewer overall problems, but the ones reported can be severe and unpredictable.
Key differences
- The GLC has 1,288 complaints over 10 years, while the A-Class has only 80 over 4 years, but the A-Class still reports serious sudden shutdowns and transmission failures.
- The GLC has 3 recalls, including electrical, structure, and steering issues, while the A-Class has no recalls on record.
- GLC owners frequently report engine misfires, headlight moisture, and limp mode, whereas A-Class owners report complete shutdowns while driving and transmission malfunctions.
- The GLC has 64 crash-related reports and 2 deaths, while the A-Class has 3 crash-related reports and no deaths, though the lower volume may reflect fewer vehicles on the road.
- Check for moisture inside the headlight assemblies, as owners report condensation leading to complete headlight failure.
- During a test drive, listen for engine shaking or misfires and watch for a check engine light, especially around 65,000 miles.
- Test the transmission for any hesitation, sudden shifting, or stalling, particularly at low speeds or when accelerating from a stop.
- Ask if the car has ever shut down while driving or entered limp mode, and check for any related service records.
Before you buy
- Run the VIN on NHTSA.gov to confirm whether any open recalls apply, especially for the GLC's electrical and steering recalls.
- Take a long test drive that includes highway merging, stop-and-go traffic, and backing up to check for stalling, limp mode, or transmission issues.
- Have a trusted mechanic inspect the engine, electrical system, and fuel/propulsion components for signs of the reported problems.
- Ask the seller for all maintenance records and specifically inquire about any history of engine misfires, headlight moisture, or sudden power loss.
- For the A-Class, pay close attention to any signs of transmission shudder or unexpected neutral engagement, and consider a pre-purchase inspection focused on electronics.
