 Various sensors always seem to be burning out, especially O2 sensors. I've gone thru 5 in the last 2 years. I also had the CD changer replaced 4 times. If you're going to buy one of these get the extended warranty! I wish I had splurged and bought the MDX.  At 35,000 I got backed into by a dump truck and it has never ridden right since.  Can't really blame the vehicle for this, but after 8 trips you would think the dealer could fix the horrible vibration. I'll keep this as a beater and buy a fun car to drive.
