So dealer checked on Friday and wasn't able to reproduce the issue. Said brakes were fine and no abnormal wear or warped rotors.
Hello 18cx9gt,
Precious few dealers are going to have much desire or motivation for solving this problem for you. This is the unfortunately state of affairs involving most Dealer Networks nationwide. Having said that, Brake Maintenance and Replacement is something that you can learn to handle yourself.
My brand new 2018 Signature began squeaking in the front after 15k miles. I've read other CX-9 owners all the way back to 2016 reporting the same.
- I did a routine oil change and tire rotation.
- Acetone cleaned/washed rotors
- Light-Cut polished and buffed rotors
- Acetone cleaned/washed pads
- Entire under-car clean and lube (if it moves it got lubed and/or conditioned with appropriate cleaner)
The squeaking went away. I paid $35 for the first hour of rack time at my local DIY garage (prorated at 15 minute intervals after the first hour) plus fuel getting there and back. I was in control of the entire process. No dealer taking me for granted and lying to me about break squeal after 15k being "normal" for a brand new vehicle. And, no fear of taking my vehicle in with one problem and getting it back with 2-3 other problems that were not present before.
The Brake System on most modern vehicles is not that difficult to understand and maintain yourself. It is my personal opinion that the brakes on the CX-9 are adequate. I plan to make mine exceptional by replacing the OEM system with a Performance Street system including new rotors, pads, calipers and lower (steel braided) hoses - once I do the homework required to make certain the system will work with the CX-9.
