no issues with my display, unit is well mounted and requires a bit of effort to move, its also lowest position close the tank. '23GT
at my dealership our service manager is a serious techie and I can talk with him whenever I need to, but generally not to the techs directly.
I record videos (if I remember) wherever problems are intermittent so the dealership has evidence and not just a customers interpretation of issue.
heat does sound likely to be the culprit, that said it gets hot in south africa, will ask the service manager if he's aware of similar reports.
hope it does not become terminal over time.
best wishes
