I had a really intriguing encounter. In 2023, I purchased KONI shock absorbers. One of the rear ones leaked after 150 km, prompting its replacement. For a duration of two years, until July 2025, I believed the car's general handling had enhanced. The front ceased to dive when braking and exhibited reduced vulnerability to crosswinds. However, the rear continued to oscillate, prompting my need for firmer springs. Concurrently, the vehicle began to vibrate in the back when braking, prompting me to take it to the service centre. They examined all aspects but discovered nothing. My last recourse was to examine the shock absorbers. The front was pristine, but the back was questionable. Utterly destroyed, emitting gas leaks. I used a vehicle with defective shock absorbers for two years, mistakenly believing the issue was with the spring. I was fortunate to have two months remaining on my warranty. I have already driven 5,000 km on the new ones, and that is all I can convey. The back of the automobile exhibits no bounce whatsoever. I am composing this message in response to several remarks, including those underneath KONI's YouTube video, where consumers assert that the situation has worse compared to prior conditions. I assume they possess compromised shock absorbers from an initial manufacturing batch. I am now fully content; I too experienced what you described on a rough highway—trucks began to overtake me. Today is ideal.
