Extremely costly once your warranty expires!!!
 First, please know this is not a gripe review.  This is just factual.  I absolutely love everything about this car except its reliability.  These are the problems I've had with it:* 23,000 miles:  Steering column rubbing/squeaking noise. This occurred during the warranty period and was taking care of.* 51,700 miles:  Turbo actuator fails.  Costs me $750 at the dealer since I was out of warranty.  I called corporate seeking assistance.  They declined to cover even though it was just out of warranty, they have a hard line, so they declined to help.* 52, 900 miles: The steering noise is back - dealer will not cover it. This is just a nuisance, so I declined repair.* 54,300 miles:  Engine begins smoking during routine city driving.  Valve cover gasket $902.79 + Oil filter housing gasket $656.99 for a total of $1,576.40 with tax.This is a very fun car while it's new, but just know that the glamour dies out quickly.  Honestly, I regret not buying another reliable Honda/Acura.  I still own my 2001 TL which now has over 417,000 miles on it!
