NHTSA Complaint #11479641 — 2022 VOLKSWAGEN ID.4

While driving with the adaptive cruise control enabled at 60 mph, I entered a 65 mph speed zone, so I attempted to increase my speed setting pressing the “+” control a couple times on the steering wheel, which should added 2 to 10 mph to the current setting, depending upon how firmly I pressed (+1 for light, +5 for firm press). Instead, it increased to 100! As fast as this car is, it could have been well above the limit in seconds so I furiously hit the “-“ button until getting to 65, but the speedometer showed that the car was only going around 47 mph. Clearly, something was wrong, so for safety, I disabled the speed control entirely. After resuming a safe speed, I looked again at the display and realized the problem. The adaptive cruise control display had switched on its own to displaying the speed setting in kilometers per hour, while the speedometer continued to display in miles per hour. The danger here is that it caused confusion and minor panic while driving on a 65 mph highway. Thankfully, I kept my head and the traffic was light, so in the end, there was no damage done. Once off the highway and on a quiet street, I was able to capture a photo of the display. I tried turning the car off and on and rebooting the infotainment display, but neither corrected the problem. I found that going into settings and switching my preference for speed display from miles to kilometers, then back again resolved the issue.
