At a glance

  • Years: hatchback W177 and saloon V177, built 2018 to 2025.
  • Reliability: 3/5. Many recalls, most of them small. The brake and ESP campaigns and the gearbox matter most.
  • DIY: 2/5. Checks need no tools, but brake, ESP (stability control) and gearbox work needs a workshop.
  • Prefer: a car with dealer proof that the 2018-2019 brake and ESP recalls were done, and oil invoices.
  • Avoid: a car with no proof of the brake recalls, a gearbox warning, or low oil at a standstill check.

Engines and gearboxes

  • Petrol M282 1.3 (A 160, A 180, A 200): no guide. Three German sites report higher oil use, and no official Mercedes action was found. Two sites mention carbon deposits from direct injection; one calls them normal.
  • A 250 e plug-in hybrid: no source names a hybrid-system fault, so none is listed.
  • 7G-DCT dual-clutch gearbox (petrol and K9K): the faults are in the 7G-DCT guide. The gearbox oil recall is in the Recalls table.

Before you buy

  1. Ask a Mercedes dealer to check open campaigns by VIN. Check the brake fluid level and look for wet fluid at the rear brake hoses. Bad: low fluid, a wet hose, or no record of the 2018 rear-axle repair.
  2. Press the brake pedal at a standstill. It should feel firm and not move sideways. Bad: a hard or loose pedal, or no record of the brake-pedal campaign.
  3. Look for a brake or ESP warning light. A scanner reads ESP and ABS (anti-lock brakes) fault codes. Bad: a warning, or no record of the ESP unit replacement. Needs a scanner.
  4. Ask for proof that the air conditioning drain-hose campaign was done. Run the A/C and check that it cools and the car starts without warnings. Bad: no proof, or electrical warnings. Needs a scanner for electrical fault memory.
  5. On a cold test drive, pull away gently at low speed. Bad: jerks, a gearbox warning or limp mode (reduced power). A scanner reads gearbox fault codes.
  6. Check the oil level on the dipstick at a standstill. Ask for oil invoices that name the grade. Bad: low oil between services, or no record of the grade.
  7. Look around the turbocharger and its feed pipe for oil. Bad: oil on the turbo or its pipe.
  8. Check the ISOFIX (child seat anchor) brackets on the rear seats, and ask for proof of the campaign on cars built in 2020. Bad: no proof for a car built July to September 2020.
