Should car shift into 8th in 'polstar' mode?
 

All,

We have a 2019 xc90 T6R with the polstar chip. This weekend I noticed that the car will not shift into the 8th gear when in the polstar mode while traveling on an interstate for extended period of time. Regardless of speed, cruise being used, throttle input, it will not shift into the 8th gear. Is that expected? Called two local volvo dealers and neither can tell me whether that is expected.

Thanks,
Tom
