Open the full vehicle complaint log (all categories)THE DASHBOARD SPEEDOMETER AND TACHOMETER GAUGES CANNOT BE ILLUMINATED WITHOUT TURNING ON PARKING OR HEADLIGHTS. THESE GAUGES CANNOT BE SEEN DURING THE DAY WHEN THE DASHBOARD IS SHADOWED. ISSUE HAS BEEN REPORTED ON SIENNA CHAT BOARDS AND NUMEROUS TOYOTA SERVICE DEPARTMENTS.
IN DAYLIGHT, WHEN HEADLIGHTS ARE OFF OR AUTOMATIC, THE SPEEDOMETER DOES NOT ILLUMINATE. WITH HEADLIGHTS ON, ILLUMINATION IS VERY FAINT AT ITS MAXIMUM SETTING. THE DISPLAY IS SO DARK THAT IT CANNOT BE RELIABLY READ. WITH SUNGLASSES, IT IS IMPOSSIBLE TO READ THE SPEEDOMETER. NOTE, THIS IS AN ANALOG SPEEDOMETER, AND THIS MODEL DOES NOT HAVE AN ADDITIONAL DIGITAL SPEED DISPLAY. AN INTERNET SEARCH INDICATES THAT THIS PROBLEM IS UNIVERSAL FOR THIS MODEL/YEAR (NOT A DEFECT IN MY VEHICLE). IT CREATES A HAZARD BECAUSE ONE CANNOT EASILY DETERMINE SPEED. (AT NIGHT THERE IS NO PROBLEM, SINCE THE DASHBOARD LIGHTING IS SUFFICIENT IN THOSE CONDITIONS.)
THE CRUISE CONTROL BACKLIGHTING ON THE "CONTROL STALK" BLINKS/FLASHES ERRATICALLY IN THE DRIVER'S PERIPHERAL VISION. THIS IS QUITE DANGEROUS AND DISTRACTING. THIS HAPPENS AT ALL SPEEDS AND DRIVING CONDITIONS BUT SEEMS TO BE WORSE WHEN HAVING TO TURN THE STEERING WHEEL MORE (I.E. A PARKING LOT VS. CHANGING LANES ON THE HIGHWAY).
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
