brp/seadoo 2013 seadoo gtx is 260 limited Nationwide

I boughrt a 2013 seadoo gtx is 260 the ski was bad from day one  i called brp that is the manafcture of seadoo told them the story that i got the ski and barnd new it had a defect and ski started siniking and water came in to the engine  they send me to a dealer the dealer fixed the damage it was a defected carbon ring, after that i took the jetski to the water it was not fuctioning ok took it back it had a bad intercooler,the ski had many issues the rteason why i say seadoo are ripoffs is this last summer the jetski had no power at all it was by the dealer for 2 months because brp was giving the dealer a very hard time replacing parts, it came to  point wher they can not find out what the issue is i get a phone call for the customer service manager at seadooamed Damian he said to me there is nothing we can do i will give you one thousand off on yuor next purchase so here i am with a $17.000 jet ski that i can not sell or do anything with the ski it is under warrany untill april 2017 the parts that they changed were 2 intercoolers supercharge 2 clusters 2 carbon rings the suspetntion was bad so how can a manafcture not honer the warranty and why i did not get a replacmet i will never do buisness with them again  n
