As a long-time owner of a used GLK for ten years, I've noticed several common issues. First, the suspension system, especially the air suspension, is prone to leaks or shock absorber wear, leading to excessive bumpiness over potholes. Repairs can cost several thousand yuan, which is quite a hassle. Second, there are minor electronic glitches, such as a laggy central control screen, malfunctioning AC buttons, or Bluetooth disconnections. These aren't major problems but do affect daily use. Third, engine-related issues include occasional turbo lag, startup vibrations, or fuel pump failures at higher mileage. Fourth, interior aging is evident, with wrinkled leather on the front seats or faded steering wheels, making the car look old but not affecting safety. Overall, when buying used, it's essential to check these areas, not skimp on maintenance, and regularly change the oil to reduce major repair costs.
