I came in excited to lease my first 2016 Sorrento. I did all the research and felt I was confident for the battle. I left quite pleased with my out come. Not even had it for a month I noticed the back windshield nozzle leaking fluid every now and then. Was enough to cause white streaky residue stains on my back window within a month's time. Seem to stop after awhile but once used will start the process over again. Went in to fix 8 months later of owning the suv to get the nozzle replaced was sent home to order a part, which took a week for the part then back again. I noticed immediately upon leaving the dealership that the streaks were down the window again. Went inside to ask and was told it was normal since a new nozzle was put in. I continue to watch and over a weeks time the stream of the streak got wider since haven't used my rear windshield wiper to prove a piont. Took back for early morning drop off since I work grave I just dropped it off at 530am. Got a call at 7am telling me that they can't fix on a Saturday not enough guys in garage. I once again explained that the nozzle is leaking that it needs to be fixed again. The guy proceeded to tell me that is normal for the systems to pressurized and to leaks fluid. Really! I asked then show me all the cars on the lot with leaky streaks running down their back window. They told me I will get a phone call back from the guy that helped me before to explain how it works. Not even 30min later the same guy called back telling me that he spoke to the mechanic that fix the original nozzle, and that he will order the second part which is some kind of check valve." I said ok". 3 wks go by and no phone call letting me know my part is in. Finely called back spoke to a women which had to call me back twice. They are ordering the part again and were unsure way the part was never order the first time. A wk later got the call. "Your part is in" . Dropped off at 530 am for my 7am appointment, (remember I work graves) got a call at 9ish it was done. Picked up at 2pm to see there was again white streaky stains running down my window. I want in to ask them why this isn't being fix. Told them I lease and i don't need you guys coming back on me about it. then again was told its normal. This is not normal! I drive these streets everyday and you don't see leaking streaks down ppl back windows. I tried to argue these facts and that there was nothing they could do but replace it again, and was told the odds it will stop are slim. I'm so sick to my tummy I left crying. I know this will effect me when the time comes to turn in my car. I love my car and take great pride to own and take care of it. These ppl don't take care of thier customers at all. No remorse about feelings, no real answers was given. I will not continue my loyalty here once my lease is up. What a shame. Pls consider going eles where. I'm stuck in this lease and need to play it out. If you have an option then go someplace with good mechanics. Super sad face. :(
