i own an 07 acura TL-S myself, ive had it for about 2 years too, the car is fine, resell value sucks!...specially if you been caught in a small fender bender.
a few problems ive had are minor, more like sensors going ballistic on me, nothing serious.
- gas casket sencor always goes off, telling me i didnt tighten correctly.
- tire preassure senosrs tend to go off aswell, this went n for a while until i went to the dealer to get all four of my tires replaced.
- maintanence at the acura dealer is shady, my experience with ny and nj dealers is that they do everything in their power to blow you off if you bring the carin with a problem, my tire sensors were going off for about a year and they kept telling me it was due to temperature changes, it wasnt until i dropped 800$ ofmy own money on tires that they took the time out to replace my sensors which were all shot! BEWARE of dealers.
THE BIGGEST ISSUE IVE HAD BEFORE I FORGET AND I THINK THIS AN ALL AROUND THING WITH NEW ACURAS BECAUSE IT HAPPENED TO ME WITH A LOANER 2009 TSX IS, THE EFFINBATTERY. I HAD TO GET MINES REPLACE BECAUSE SINCE THE VERY BEGINING IF I LEFT MY HAZARD LIGHTS ON FOR LONGER THAN 40 MINUTES OR THE RADIO ON WHILE THE CAR WASIDLED FOR HALF AN HOUR, MY BATTERY WILL BE IMMEADIATELY DRAINED.
all in all i think its a good car, if i could do it all over i would have waited a few months and gotten the mercedes C-class....for the same 40k i got my tl-si could have gotten the Mercedes.
I donot recommend you get a pre-owned.
