Two problems related to exterior lighting have been reported for the 2017 Toyota Prius. The most recently reported issues are listed below.
Since we had purchase our car Prius v four with drl (day running lights)(vertical led unit in bumper) they never worked properly-hence not visible in our accident. . Unlike other earlier models the user could adjust the sensor and turn this feature on or off-but now the feature can only be performed by a Toyota service mechanic. The feature also operates off a day light sensor that also cannot be adjusted by the owner of the vehicle. Hence since this is a safety feature noted in faq on Toyotas site it should be considered for a recall.
Under certain daytime conditions the dashboard display becomes temporarily unreadable due to pupillary delay adjusting to unilluminated dashboard display of speedometer. The dashboard, by design, is not illuminated during daylight. Because of this, under bright sunny conditions, when the driver glances at the speedometer display, his eyes cannot immediately adjust to read the vehicle without taking his eyes off the road ahead to know his speed.
