Is anyone else having issues with the speedometer gauge randomly being incorrect by +1-15MPH? It seems to randomly increase by about 1MPH each start until it randomly resets back to 0. The only way to know my true speed is to either have the digital speedometer on the dash, or notice how many MPH the gauge shows at a stop and then subtract that from the current number at speed. I figured that an update would eventually fix it but it doesn't seem that will happen.

Note: This is stock wheels/tires.

Make sure you didn't accidentally switch it from mph to km... Other than that might be a bad cluster

There is a cluster flash to fix this issue, mine would be up to 5 mph higher on the analog and it would not go to zero when stopped. Flash took care of the issue for me.

Thank you, I will run it by the dealership. Every other time I have taken it in, they have wanted to keep it a week and nothing gets fixed. Good to know that there is an actual fix.

I would think that the analog and digital pull from the same wheel sensor, but who knows.

Ask them to perform TSB 08-108-18 REV A, it's the flash that you most likely need.
