CarPlay pixelation persists on iPhone 17 after iOS 26.1 update

Just updated to iOS 26.1 (on my iPhone 17 Pro Max) and unfortunately still experiencing the same CarPlay pixelation issues as on previous iOS versions. Crazy that Apple has not fixed this yet. Having this issue on a 2019 Mercedes vehicle. Recently rented a 2025 Kia Telluride with no issues. I’ve called both Apple and Mercedes tech services, and each blamed each other for the issue. Anyone else still having the CarPlay disconnection/pixelation issues after updating to 26.1 with an iPhone 17?
