The speedometer keeps malfunctioning. The speedometer needle sticks at a higher speed after decelerating or stopping, making it impossible to know what speed you are driving. This happens mostly when the weather warms up, spring/summer/fall. Making a hard braking stop, like at an intersection, will sometimes cause the needle to drop back 5-10 MPH, as will turning the car off and back on. Most specifically, yesterday, may 31, 2019, the speedometer needle wouldn't go back down at all, and my speedometer was "pegged" past the top end of 110mph. I have researched online, and this seems to be a common and chronic issue with this model.
