well in my last trip to the infiniti dealership in AZ they somehow managed to mess my car up more than when i took it in...i drove in so they could check an oil leak and an random missfire code and came out with a fixed power steering line, a broken intake tube, and my driver seat wont go down anymore, not to mention i drove in with like 3/4's of a tank of gas and recieved it with 1/4 tank full..

i told them the intake tube was not broken because 2 days earlier i had bought a new battery and inspected the whole engine bay and checked fluids dude argued the tube plastic was old and dry and its not its flexible and still in new condition.my driver seat wont go down and said it was like that and im like no i checked that too before takin it in...so fudge infiniti on bell

...didnt want to own up to anything

and i had to leave before i got more pissed off...the car sputtered off way worst than when i took it in...so i ghetto rigged the intake hose with a pice of plastic on the tear and duck tape all around it so it could have a secure seal and then i cleared the check engine light. After a couple miles of driving and a new load of gas i started keeping track of my mpg on the settings menu on the car because it felt somewhat slower and looked like it was wasting to much gas and my suspicion was right before i was getting 19 mpg street and 21 mpgs high way and now its like 15 mpgs street and 17 or 18 mpgs highway.thr driving pattern is the same same driver same 91 octane summer gas and same store (qt gas )no check engine or maintance light ..not to metion after the repair it feels havier and a tad slower.so iwas thinking it might be the intake tube having a small leak but the loosing on the mpgs i have no clue i read something about a module/attachment the dealership came out for these vehicles for thr gas pedal and to save gas (i think) but i cant find the topic on the search columb here...any1 got any suggestions on this and a better shop to take my baby here in az and its my 2002 infiniti q45 sport...
