Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“After taking my '18 hd out for lunch, the speedometer fogged up while I was inside the building (about thirty minutes - ~75 degrees outside). The entire ride home the speedometer was fogged up and I was unable to see the speed of my motorcycle or gear that the bike was in. Since the unit only has an analog tach I am out of luck when it comes to determining my speed to keep safe / lawful vehicle operation on the road. …”

“Moisture is collecting under the speedometer, forcing me not to know my speed, RPM, etc. This is very dangerous. I am on my second factory replacement of the unit.”

NHTSA complaint #11319072, filed 2020-03, 2,000 miles

“Condensation forms inside the instrument cluster while driving, rendering the speed indicator unreadable. This is a very serious safety hazard because the driver can become distracted trying to read the instrument cluster through the condensation. It's also a safety hazard because the driver can't determine their speed when the speedometer is unreadable. The condensation may also cause the instrument cluster to fail over time. …”
