Butt of car Sinks down in garage after about 3 days. Ride light is on and suspenaion defaulted to sport mode. These seemed to happen at same time, hence I mention them together. We replaced front accumulators, struts, and many front rubber parts to stop clunking noise over bumps. Car drove perfect for a few weeks then slowly started to have the fix ride light come on more and more till on all the time. Suspension acts fine front and rear but stuck in sport mode. No leaks, 29k mike Car, don’t have previous records. Clues? Guesses?
