My 2017 QX60 developed a 10kph instrument error while car is stopped. Highway radar speed checks confirmed the error. It took two (2) months for the dealer to get a replacement 'cluster'. The new speedometer worked well for four days. It then started to indicate an error of 10kph; 40kph; 120kph and finally 143kph. When I took the car to the dealer, with photos of the readings, the reading was 120kph.....so far the dealer has no answer for me. Has anybody else had a similar indication problem, and if so, how was it resolved ?
