Why does the Mercedes-Benz GLC experience severe jerking during braking and deceleration?
3 Answers
The reason for the severe jerking during braking and deceleration in the Mercedes-Benz GLC is due to sudden acceleration or releasing the throttle. The solutions to address the jerking during braking and deceleration in the Mercedes-Benz GLC are as follows: 1. Gradually decelerate to allow the transmission time to buffer. 2. Visit a repair shop to have professional technicians inspect the vehicle. An introduction to braking distance is as follows: A vehicle's braking primarily depends on the friction between the tires and the ground, with the magnitude of friction determined by the coefficient of friction. Assuming the coefficient of friction is μ, the braking distance S=V*V/2μ(g=9.8m/S2), indicating that the braking distance is directly proportional to the square of the speed and inversely proportional to the coefficient of friction. When the coefficient of friction remains constant, the braking distance depends on the speed. If the speed doubles, the braking distance will increase fourfold.
I've been driving my Mercedes-Benz GLC for over two years now, and I've also experienced jerky braking deceleration, which is quite annoying. There could be several possible reasons: first, issues with the braking system, such as uneven brake discs or calipers not gripping tightly, causing the car to jerk during deceleration. Second, problems with the transmission, especially when the automatic transmission shifts gears roughly, which could be due to software bugs or aging components. Third, issues with the suspension or tires, like worn-out shock absorbers or unbalanced wheels, affecting smooth deceleration. I recommend first checking the brake pad thickness yourself—if they're too thin, it's time to replace them, or take it to a 4S shop for a diagnostic scan. During regular maintenance, pay attention to cleaning the braking components, and avoiding sudden braking can prevent many issues. While driving, note at what speed range the jerking occurs—if it's more noticeable at low speeds, it's likely transmission-related; at high speeds, it's more likely brake-related. In any case, don't ignore this issue; address it promptly to ensure safety, as neglecting it can increase wear and affect the vehicle's lifespan.
As an ordinary person who has driven various cars, I find the brake jerkiness in the Mercedes-Benz GLC quite common. Possible reasons include the ABS system being overly aggressive, causing sudden vibrations when it intervenes during deceleration, or insufficient/contaminated brake fluid leading to unstable hydraulic pressure. The transmission is also a key factor – Mercedes' automatic transmission sometimes hesitates during low-gear shifts, creating jerkiness. From personal experience, driving habits like frequent hard braking or overloading can worsen the issue. I usually start by checking if tire pressure is normal, as unbalanced tires amplify vibrations. If a software update is needed, visiting the dealer for an ECU reprogramming can help. Safety first – don't delay if abnormalities appear; have a reliable repair shop conduct comprehensive diagnostics to prevent higher maintenance costs later. Incidentally, regular oil changes benefit the transmission through simple maintenance. Stay calm, test potential causes step by step, and don't let this minor issue spoil the driving pleasure.
