NHTSA Complaint #11621140 — 2020 VOLKSWAGEN GOLF

While driving with the cruise control set to 55 mph, the car began an uncommanded acceleration. When I looked down on the dashboard display I noticed that the cruise control target speed was set to 95 mph. I switched of the cruise control and resumed manual control of the speed. When I switch the cruise control back on I observed the target speed rapidly increase from the intended 55 mph to 95 mph accompanied by moderate vehicle acceleration. I again switched off the cruise control and resumed manual control of the speed. Sometime later during the drive a cruise control error message appeared on the dashboard. Subsequently the problem was identified as a faulty cruise control switch (part number 5G0-959-442-AE-ICX). The switch was replaced and the fault has not reoccurred over a few hundred miles of driving. While this malfunction can be overridden using the normal cruise control disconnect procedures, uncommanded acceleration poses a safety risk to driver and other motorists or pedestrians.
