1. The Transmission
The Mercedes dual-clutch transmission in A-Class models from 2019-2023 was designed for quick shifts and a sporty feel. But when it starts hesitating, jerking, or delaying gear changes, that smooth ride turns into frustration.
Some drivers report a harsh jolt when shifting into first gear. Others notice a dangerous delay when accelerating, as if the car is second-guessing itself. If the transmission is slipping, shifting unpredictably, or refusing to engage, it’s only a matter of time before complete failure.
Ignoring it? That’s how a minor issue turns into a full transmission rebuild. We reprogram the transmission control unit, flush contaminated transmission fluid, and replace failing components before it’s too late.
2. AIRMATIC Suspension Problems
Your A-Class was built for comfort and control. But when suspension components start to wear out, it feels anything but smooth. If you notice clunking noises when driving over bumps, excessive body roll in corners, or an unsettling looseness in the steering, something’s failing.
The most common culprits? Worn-out control arm bushings, faulty struts, or a failing sway bar. Ignore it, and your handling will get worse, tire wear will skyrocket, and eventually, you’ll feel like you’re fighting your car just to keep it straight.
At Fremont Foreign Auto, we rebuild failing suspension systems, replacing worn parts with high-quality components that bring back that solid, planted Mercedes feel.
3. Infotainment Freezes and Screen Blackouts
A luxury car should have a flawless tech experience. But the Mercedes-Benz User Experience (MBUX) system in many 2019+ A-Class models is notorious for glitches. Drivers report the screen freezing, random reboots, Bluetooth connectivity issues, and full blackouts where the screen won’t turn on at all.
When your infotainment system refuses to work, you’re not just losing entertainment—you’re losing access to climate controls, backup cameras, and navigation. At Fremont Foreign Auto, we reprogram the MBUX system, update software, and replace failing control modules so that your tech works like it’s supposed to.
4. Oil Consumption Issues
A Mercedes-Benz should never burn oil excessively. But many 2018-2022 A-Class models, particularly those with the M260 2.0L turbo engine, suffer from unexpected oil loss.
At first, it’s just a little low between oil changes. Then, suddenly, you’re adding oil every few weeks. Low oil means less lubrication, increased engine wear, and—if ignored—severe overheating that leads to complete engine failure. We find the cause—whether it’s worn piston rings, bad valve seals, or a clogged PCV system—and fix it before it costs you an engine.
5. Turbocharger Issues
If your A-Class suddenly feels sluggish, takes forever to get up to speed, or whines under acceleration, your turbocharger could be failing. The turbocharged A220 and AMG models suffer from oil starvation, cracked housings, and wastegate malfunctions—leading to power loss, poor fuel economy, and eventual turbo failure.
Wait too long, and your turbo won’t just fail—it’ll send debris into your engine, causing catastrophic damage. We catch turbo issues early, replace failing components, and restore full power before your A-Class loses all its boost.
6. Electrical Gremlins
If your dashboard lights up with random warnings, your windows stop rolling down, or your keyless entry refuses to work, you’re not alone. Mercedes-Benz packs the A-Class with advanced electronics, but that means more chances for something to go wrong.
The most common electrical failures? Malfunctioning battery control modules, faulty SAM modules (Signal Acquisition Modules), and corroded wiring. If ignored, these minor glitches turn into full system shutdowns, leaving you with a car that won’t start at all. We trace electrical faults, replace failing modules, and ensure your A-Class’s tech works reliably.
7. Engine Cooling Problems
Your A-Class should never overheat. But some 2018-2023 models experience coolant leaks, failing water pumps, and thermostat malfunctions. If your temperature gauge climbs past normal, your coolant level mysteriously drops, or you hear the radiator fan running overtime, you’ve got a cooling system problem.
Overheating leads to blown head gaskets, warped cylinder heads, and complete engine failure. We pressure-test the cooling system, replace failing components, and keep your engine running at the correct temperature.
