Most reported problems

NHTSA lists 3 complaints for this model year[1]. One mentions an injury, and none mention a crash, a fire or a death[1]. That is a very small pile of reports, and they are unverified. One complaint can also name more than one part of the car.

By component group, forward collision avoidance has 2 complaints[6] and unknown or other has 2[7]. Seat belts[8] and speed control[9] have 1 each.

In the complaints we read, owners describe the car braking hard on its own and tightening the seat belts when nothing was in the road[6]. One owner reports it happened at freeway speed with a child on board[6]. Another says a dealer software update did not stop it[6]. The same event shows up under seat belts and speed control[8][9].

The radar recall below is about a sensor that may stop working. The radar recall is about a sensor that may stop working, which is not the same as the sudden braking some owners describe[2][6].

Recalls

NHTSA lists 2 recalls for the 2025 G-Class[4], newest first.

Fuel economy

EPA rates three versions.

Version Rating
G550, 3.0L 6-cyl turbo[5] 17 city / 19 highway / 18 combined MPG, about $4,550 a year in fuel
AMG G63, 4.0L 8-cyl turbo[10] 14 city / 16 highway / 15 combined MPG, about $5,500 a year in fuel
G 580 with EQ Technology, electric[11] 62 MPGe combined, 239 miles of range

Both gas versions use premium fuel[5][10]. EPA bases the yearly cost on its current fuel price assumptions, not on prices when the car was new.

Engine and size

EPA lists these power ratings for the 2025 G-Class:

Size comes from Canadian-market specifications, so US models can differ slightly.

The 2025 model year has 3 complaints and 2 recalls[4]. The highest complaint count for any G-Class year is 9, in 2021[4]. The highest recall count is 13, in 2019[4]. The 2024 model year shows 0 complaints and 0 recalls[4]. These counts are not adjusted for how many cars were sold, so treat them as a rough guide.

Should you buy a used 2025 G-Class?

The complaint record is thin, with 3 reports on file[1]. Both recalls have a dealer fix listed, so confirm with a dealer that both were done on any car you consider[2][3]. The radar recall matters most, because it covers a sensor that can disable automatic emergency braking[2]. Owners in the complaints we read describe sudden braking with no hazard, so ask for a long test drive on a highway[6]. Our data does not cover price, towing or reliability scores.

Complaints submitted to NHTSA by owners; unverified reports, one complaint can name several components. Complaint counts are not normalized by sales; compare years of the same model, not different models. EPA annual fuel cost uses EPA's current fuel price assumptions, not the price when the car was new. Horsepower is the rating listed for EPA test vehicles. Dimensions are Canadian-market specifications and can differ slightly from US models.
