 I might be wrong / you have different situation but I'd like to help someone who are suffering from the issues as the same as mine.1. Creaking noise from rear suspension- fixed by dealer2. Pulling issue & tire noise at high speed - dealer's answer : no problem- My solution : Adjust wheel alignment & Changed tires to Michelin MXV4 94H(94V recommend) - It works great.3. Hands free button malfunction(sometimes)- replaced by dealer4. Cruise control "SET"/"Cancel" malfunction (50% failure)- dealer's answer : no problem - waiting for 100% failure.5. Weird noise from engine.- Using Octane 91 / 93 Gas.Now I'm feeling more comfortable after spending money & time.
