I had the infamous noisy steering whine/groan, and took the car to dealer to diagnose the problem last week. They said it's quite a common concern on 159/Brera and it's necessary to replace the ps pump and maybe the steering rack( around 1300 euros). Being a technicaly inclined kind of person, suggested to first flush and replace the steering fluid before attempting something radical. They looked at me (the "engineers") like I was trying to make them look silly: " You don't have the proper training to teach us what to do!". Okay...I'm a dentist and I'm used to tackle situations with patience before plunging into something radical. So got home, bought 5 liters of Dexron III ATF (as recommended by the manual) and spend this sunny morning flushing the entire steering system by myself. Guess what! No more noise and vibration anymore! I dont know if it's a design fault or simply the system is too sensitive to fluid quality. It's another car now...Try this before waisting time and hard-earned money!
