Video will help explain this better than words: I get this 100% of the time I accelerate past 80mph at full throttle. If I push it to 100 mph and ease off to maintain speed at 100, the yellow bars go away until I go full throttle again, then the yellow returns instantly as the power bar climbs back towards it. Since this started, I have been able to replicate this every single time I try. I just picked it up from service, they tell me that this isn't happening. They have seen the linked video and my description. I reproduced the issue on the first after picking up my car, and every subsequent attempt. Is there a known issue that can do this? Is there a word for it I can use to help them acknowledge it?
