When problems show up

No complaints for this year listed a mileage, so we can't say when problems show up.

Questions to ask the seller

  1. Were recalls 22V365000 (electrical), 21V961000 (fuel system, gasoline) and 21V197000 (body structure) done? It has 5 recalls in all. Ask for the dealer printout, or check the VIN.
  2. Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
  3. Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?

From this year's own recalls, top problems, top repair bills and Mercedes-Benz's repair notes. Recall repairs are free at any dealer.

How serious. Out of all 2 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:

0crashesaverage car: 0
0injuriesaverage car: 0
0firesaverage car: 0
1towsaverage car: 0

“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.

What owners complain about most. From owner complaints to the government.

transmission & drivetrain50%
electrical50%

Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

Before you buy, watch

Views show how many people looked up each fix, not how often it breaks. Videos belong to their creators; we link to them. The 2020 is the same generation.

Costs are the middle (median) of the dollar amounts people say out loud in these videos, so one wild number can't swing it. They aren't verified bills or sales; real prices depend on year, miles, condition and where you live. Tap Hear it to jump to the moment.

The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
