Mazda CX-9 in Georgia, United States Oct 2012 - Jun 2024
Dec 2012 2000 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 2013 13000 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 2014 31700 mi US $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 2015 42000 mi	Brake booster vacuum leak, brake booster replaced under warranty extension for that part. Had to order part but provided loaner.
Jul 2015 45000 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 2015 46200 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 2019 95000 mi US $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.
Jul 2022 128000 mi US $920	Front shocks/struts were replaced.

I was told that the gaskets were installed improperly due to the lack of room, can't see what you're doing.
