It is consistently described as a vehicle engineered to last 25 years, with many reports of examples driving like new at 100,000 miles. The 300-series LX (LX 600) receives a more mixed reception.
Best version to buy
For the 200-series, the 2008+ LX 570 is frequently recommended for its 6-speed (and later 8-speed) transmission. The vehicle's Hydraulic Suspension (AHC) is highly praised for its smooth ride and adjustable height, and models with a functioning, rust-free AHC system are considered the best versions.
Known issues

GL
Overall
Sentiment is mixed and heavily dependent on model year, engine choice, and ownership expectations. The X164 generation (pre-2013) is described as a "dinosaur" with a less refined driving experience but is noted for its non-turbo engine reliability. The facelifted X166 generation (2013-2019) is widely praised for its significant improvements in driving dynamics, comfort, and interior quality, offering a "magic carpet" ride with its adaptive air suspension.
Best version to buy
For the X166 generation (2013-2019), the facelift models (2017-2019) are frequently recommended for their updated and more reliable engines (M276 turbo V6, updated M278 V8). The GLS550 (V8) is highlighted as providing an ideal blend of smooth, abundant power and luxury, described as "one of the best full-size 3 row crossover experiences." The non-AMG body style with standard 20-inch wheels is preferred over AMG-line models with larger wheels for a better ride quality and lower tire replacement costs.
Known issues
- ⚠Air suspension failure: Components like the pump and air springs fail, leading to expensive repairs (quoted at ~$5k minimum). Frequency: very frequent.
- ⚠High maintenance and repair costs: Routine servicing, parts (e.g., brakes, tires), and repairs are significantly more expensive than mainstream brands; described as "flagship maintenance costs." Frequency: very frequent.
- ⚠Electronic system failures: Flaky blind-spot monitoring, lane departure warnings, infotainment issues, and power seat malfunctions. Frequency: recurrent.
