Make sure you go with mechanic...my car had screeching handbrake few days after purchase..back to dealers, mechanic said he couldnt hear anything...I left...two minutes later heard it,..back I go n inisted he go with me...yes, issue...he fiddled with it...drove off still there..back I go again...he fiddled with it...off I go...half way home, about 30mins away I pulled on hill, pop on my handbrake and nearly hit the car behind me, hed turned the handbrake off, only worked on last two highest clicks...lost all faith in that dealer so got it sorted with different mechanic...
keep at it is my advice...
