Mercedes-Benz Models Ranked by Reliability for 2026

Shopping for a new Mercedes-Benz usually means chasing comfort, cutting-edge tech, and that unmistakable badge appeal. But none of that matters if the car won't hold up over time. D. Power's quality and reliability ratings for the 2026 model year, along with five years of historical data.

The list focuses on models with enough track record to actually judge, since several newer or upcoming Mercedes models haven't been on the road long enough to prove themselves.

D. Power. It's the brand's best-selling sedan and one of the most affordable at $49,650, often described as a mini S-Class for its design and premium features. The ride is serene, though not as sporty as a BMW 3 Series. The current fifth-generation model has had four years to work out bugs before an all-electric C-Class arrives next year.

There have been four recalls, including one for a seatbelt restraint and a more severe fuel pump failure, plus repeated complaints about the active braking system triggering for no reason. Still, overall consumer feedback stays positive, and its average annual maintenance cost of $739 is below the Mercedes average of $908.

In fourth place is the GLE-Class with an 80/100 rating, which it has held for three straight years. This midsize SUV, formerly known as the ML-Class, comes in a variety of powertrains, from a four-cylinder to a plug-in hybrid and V8 versions, starting at $62,250. Owners appreciate the smooth performance and solid build, though the infotainment system isn't the easiest to use, and voice controls have been praised for accuracy.

It has seen recalls, including an airbag issue in early models, and frequent complaints about a faulty check engine light. Maintenance runs higher than average at about $1,200 per year.

The E-Class sedan also scores 80/100, tying with the GLE. This sixth-generation model, introduced for 2024, starts at $65,200 and blends high-quality materials and classic comfort with modern tech and hybrid options in the AMG E53. Despite being new, it earned its rating from initial customer feedback over the past two years, which is notable since first model years often have more problems.

Issues include unnecessary forward collision avoidance activations and a recall for a high-voltage battery fire risk, but the overall complaint count remains relatively low.

The GLA-Class, the cheapest Mercedes at $41,500, comes in second-to-last with a 78/100 score. It's more like a large hatchback than a true SUV, offering decent passenger space but less driving fun than a BMW X1. The main concern is the M260 inline-four engine, which has been linked to misfires from premature exhaust valve and seat guide wear.

A notable recall involved door detection failure that kept the parking brake from engaging automatically. Its average maintenance cost is $987, close to the brand average.

Rounding out the list is the GLS, also at 78/100, showing that paying more for a bigger, more luxurious SUV doesn't guarantee higher reliability. Praised as the SUV equivalent of the S-Class, it offers expansive screens, a smooth ride, and effortless power. But owners have complained about rough downshifts, limited small-item storage, slow electric-folding second-row seats, and the complex air suspension may need attention sooner rather than later.

It has faced recalls, including one for the fuel pump delivery module, and costs nearly $1,300 annually to maintain.
