Reported problems

NHTSA has no owner complaints on file for the 2026 G-Class. That includes no reports of crashes, fires, injuries or deaths[1].

That is good news, but it is not proof that nothing can go wrong. Complaints are unverified reports from owners, and a count of zero only tells you that none have been filed[1].

Recalls

NHTSA lists 0 recalls for the 2026 model year[3]. There are no recall items to check on this car right now.

Fuel economy

The 2026 G-Class is rated in three versions. The EPA numbers are:

Version Rating Annual fuel cost
G 580 with EQ Technology (electric)[4] 62 MPGe combined, 239 miles of range not listed
G550 (3.0L 6-cylinder turbo)[2] 17 city / 19 highway / 18 combined MPG $4,550
AMG G63 (4.0L 8-cylinder turbo)[5] 14 city / 16 highway / 15 combined MPG $5,500

Both gas versions use premium fuel and 4-wheel drive[2][5]. The EPA fuel cost uses its current fuel price assumptions, not the price when the car was new.

Horsepower as rated on the EPA test car list: 443 hp for the 3.0L 6-cylinder[6], 577 hp for the 4.0L 8-cylinder[7] and 579 hp for the electric motor[8].

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

Should you buy a 2026 G-Class?

On the data we have, the 2026 G-Class has a clean record, with 0 complaints[1] and 0 recalls[3]. Fuel economy depends a lot on the version, from 15 combined MPG for the AMG G63[5] to 62 MPGe for the electric G 580[4]. We do not have safety ratings, reliability history or price, so those need checking elsewhere. A clean record this early is a good sign, not a guarantee.

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.
