On the 2019-2023 Mercedes-Benz A-Class 2.0L M282 Turbo, the 8G-DCT dual-clutch transmission develops a shudder during low-speed acceleration, similar to driving over rumble strips. The clutch packs overheat in stop-and-go traffic, causing judder and vibration during engagement.

This issue also affects: Fiat 500L, Mercedes-Benz B-Class, Mercedes-Benz GLB

Common Symptoms

Shudder during 1st-2nd gear acceleration
Vibration at low speeds similar to rumble strips

How to Fix

Update the DCT software to the latest calibration. In persistent cases, the clutch assembly may need replacement. Avoid prolonged creeping in traffic — use the brake instead of riding the clutch at low speed.

On the 2019-2023 Mercedes-Benz A-Class, the front MacPherson struts develop a clunking or knocking noise over bumps and rough surfaces. The strut mount bearing wears prematurely, and the strut itself can develop internal valving noise. More common on vehicles with AMG suspension.

This issue also affects: Chevrolet Colorado, Fiat 500L, Mercedes-Benz CLA

Common Symptoms

Clunking noise from front over bumps
Knocking when turning at low speed

How to Fix

Replace the front strut mount bearings first ($100-200 per side). If the noise persists, replace the strut assemblies. Use OEM or Sachs (OEM supplier) replacement struts for proper ride quality.
