Why does the Mercedes-Benz GLE feel unstable when driving?
2 Answers
Mercedes-Benz GLE feels unstable when driving due to tire issues, inaccurate four-wheel alignment, and loose screws at the connection points between the frame and suspension. Reasons for tire issues: Quality problems with the tires themselves, rubber aging, uneven tread wear, or punctures in the tires. Reasons for inaccurate four-wheel alignment: Uneven loading of items, mainly if the trunk consistently carries heavy items concentrated on one side, inconsistent tire pressure on both sides, damaged springs and shock absorbers, excessive wear of vehicle chassis components leading to abnormal gaps, failure of front shock absorbers. After the front shock absorbers fail, the suspension on both sides becomes uneven during driving, resulting in uneven force distribution and causing the vehicle to pull to one side.
Last time I drove my brother's Mercedes-Benz GLE on the highway, I clearly felt the steering wheel was a bit floaty. When encountering uneven road surfaces, the body swayed noticeably from side to side. Upon self-inspection, I found all four tires had different pressures, with the right front wheel being 0.6 lower than standard. Uneven tire pressure significantly affects traction. Later at the shop during a wheel alignment, the mechanic said excessive toe angle deviation was causing tire wear. These large SUVs have soft suspension tuning - any misalignment immediately makes them feel floaty. Another detail: during car washing, I noticed a balancing weight had fallen off the front wheel. With these large rims, missing just one counterweight makes the steering wheel vibrate noticeably above 80 km/h. These detailed issues really affect driving refinement.
