How Do the Lexus GX and Mercedes-Benz GLE Generations Compare?
Verdict
The Lexus GX is more reliable than the Mercedes-Benz GLE, scoring 80/100 vs 67/100.
Clear lead for the GX. Its owner complaints are few, and its worst reports are small clusters, such as brake shudder on long grades and dashboard blackouts. The GLE has far more complaint volume, and its problems hit the expensive parts: cylinder heads, transmissions, and driver assist braking. Many GLE engine failures show up near 50,000 miles, just after warranty ends. The GX also has a few serious stall reports, but they are rare. For a buyer who wants the lower chance of a big repair bill, the GX is the safer used purchase by a wide margin.

What Are the Common Problems With the Lexus GX and Mercedes-Benz GLE?
Scattered and small describes the Lexus complaints. Brake shudder on steep grades, dashboard and head-up display blackouts, and a vibration that alignment does not cure lead the list.

Cylinder head failure, harsh shifting from solenoid or valve body faults, water in the footwells, and phantom braking from adaptive cruise all recur. The GLE also has crash-linked reports in four areas: electrical, power train, speed control, and brakes. On the GX, only one electrical complaint is crash-linked.
