Common Problems with the
2023 Tesla Model Y

The 2023 Model Y benefited from the "Comfort Suspension" introduced from February 2023, which significantly improved the ride quality by softening spring rates and increasing top support stiffness. Boot water ingress was reduced on later builds, and the January 2023 price drop made these excellent value.

What changed for 2023

  • •Comfort suspension introduced from February 2023
  • •Boot water ingress reduced on later builds
  • •Significant price drop in January 2023
