2018 Cx-9 GT that has experienced spider cracking in the upper right corner of the infotainment screen (the cracks are inside the screen). This started after the car sat at the dealers lot in cold temps while waiting for repairs to the engine Feb 2022 (mileage on car at that time as about 36K). Mazda had issues a Service Alert on 2/20/18 in regards to this issue for 2016 - 2018 CX-9's (along with other model of similar years). No mention to me by dealer (who i have taken car to for all service matters from 1st day of purchase). Mazda then issued a Warranty Extension Program letter dated 5/06/20 to Dealers, Service & Parts Manager that they would extend warranty coverage to fix this issue, but only for 2016 & 2017 CX-9 vehicles. Over time the cracking has gotten worse & is slowly growing in size. (some other owners have it cracking in different parts of screen, which renders the touch screen useless). Mazda should include 2018 in the Warranty Extension Program, so this issue can be resolved for all years affected.
