I arrived at the dealership near opening and was told it would take about an hour to diagnose my issue, which was (my car shut off during my use while driving, in addition my shifter will no longer move without using a key in the shift lock insert) I explained that I have visited 4 mechanics in the last year of the one year and four months I have had the car. I explained that I have been very afraid to bring the car to a dealership because of other experiences people have had at dealerships but after the car shut down during my last time on the road I was too scared to continue with the previously unsuccessful mechanic visits. I waited from the time I arrived around 11:00 a.m. until the dealership closed at 6:00 pm and was told they don't know what is going on, and they will need to keep the car. I work in customer service and I understand what it feels like to have a tough customer so I did not complain I just asked what would be done, they told me I would have to rent a car and as far as what was wrong with the car they stated that they would be taking care of three recalls on the car and they believed it might be the transmission and that that would be covered under my powertrain warranty. A few days later I was contacted being informed that it was the transmission and that they would have to replace the transmission and this would resolve all the issues. However this repair would cost $3,000 or more because I was 331 miles outside of the 60,000 mile warranty that they stated I had previously. Even though wrong expectations were set I was not upset I just asked if anything could be done, they told me to contact corporate and proceed from there to see if an exception could be made. So after calling corporate they said they would cover it with a $500 deductable I agreed and called back the dealership and asked to have the repair completed. I could not keep the rental longer because I could not afford it so I asked to drop it off, I told them I get off work at 5:00 and would come right after if that was okay and I could be there by around 5:30 - 6:00 and they said "yes as long as it is before closing". I arrived the next day at 5:40 to drop off the car. This is when it got really bad! I walk in and cannot find Maggie Martir who was the person who worked with me so another lady was there, I asked the lady if I could drop off the rental and I was told "I have somewhere to be so I'm not sure what you are going to do?" Shocked I asked if I was correct in that they closed at 6:00 p.m. She stated sarcastically "yes but I have somewhere to be so...." I didn't know what to do so I asked if that meant I would have to pay for another day with the car because nobody was here while they appeared to be open and I called before coming in. She said "who did you work with?" I said Maggie and she stated "so Maggie is not here so I don't know what you are going to do." She then got very irritated and said "just go over to the receptionist because I don't have time for this, and give her the keys with the paperwork." He receptionist couldn't find any paperwork about my car or the rental and frustrated the lady said "just write your name on a piece of paper and leave he keys and we will call you tomorrow" i asked if I would be charged with the appropriate amount of days and she said "we will call first so yes" low and behold the next day I received NO PHONE CALL and yet a charge on my card... Again I did not complain... Lastly I was out of town so my father whose name is in the title with my name went in to pick up the car after I called to let them know about this. When they went to pick up the car the lady accidentally charged them for the repair and the rental again. And so they asked to be refunded the rental cost and the employee said yes but they needed manager override, Michael J. PERISCO JR. Came over to help with the override and asked for the receipt for the rental, the employee stated that it was her mistake but the manger insisted for the receipt, and said he would not give them back their money without it, now we were outraged because I was not even called or given a receipt only charged without being called so now this was out of hand, eventually he gave the refund after some arguing. Now the icing on the cake that has me more angry then ever is that the issue is persisting, the car is jumping again and I am afraid it will shut off again, and there appears to be a part that was forgotten to be placed back in the car because I can now hear the engine very loud in the passenger cabin as if there is a covering or something missing. However I am so angry with my experience that I do not want to go back to this place, please help me. I almost never want to buy a Nissan again and if I am honest I am using these feedback channels for now and if this doesn't work out I will be contacting the better business bereau and the media about this transmission issue specifically and this dealership in new Rochelle.
