| Dec 20122000 mi | Rubber seal surrounding headlight on driver's side was improperly installed; replacement required removal of bumper, grille and headlight assembly (4 hours to complete), loaner car provided | ||
| Aug 201313000 mi | Windshield wipers got out of sync and crashed into each other. Driver side wiper arm bent and passenger side wiper arm stripped at base (where it attaches to motor). All parts of both wipers replaced, but one had to ordered. | ||
| Oct 201431700 miUS $80 | High beams range and quality had significantly degraded since new. Replaced with Sylvania Ultra bulbs. Tried to replace bulbs myself but could not fit my hand in the tight space to insert and secure bulbs. | ||
| May 201542000 mi | Brake booster vacuum leak, brake booster replaced under warranty extension for that part. Had to order part but provided loaner. | ||
| Jul 201545000 mi | Started hearing a loud, intermittent metallic rattling sound after last repair trip. Heat shield on exhaust was loose and the entire exhaust system is being replaced per an extended warranty on the parts. Six days and parts not here yet. | ||
| Aug 201546200 mi | Repair of exhaust system noted in 7/15 were completed after waiting 22 days for parts. Noticed heat shield rattling when A/C kicked on a few days later and had to return to dealer for repair. | ||
| Feb 201995000 miUS $725 | Transmission began shifting into D (from P, R or N) very harshly a few months ago. I located a TSB that identified this issue as "shift shock" and indicated that a TCM re-flash would correct the issue, if TCM could be reflashed. Based on production date/VIN, the TCM itself could require replacement. A new TCM lists for just over $1k! Luckily, my TCM was one that could be re-flashed. The intial charge for this was $159, but I negotiated it down to $75. I have also noticed some odd behavior in the transmission's downshift behavior. It has always been aggressive about downshifting for engine braking, but it had become overly-agressive on an intermittent basis. The dealer traced this to a faulty Throttle Pedal Position Sensor. The price for this repair was around $375. Finally, they were very insistent that new Synthetic ATF was essential to ensure everything worked well. I was fine with the change, but the $349 price tag was a different story. I did some research, we went back and forth a few times and finally I got them to agree to do it for $210. It's still steep, IMO, but it's worth it for the peace of mind. | ||
