Symptoms
The emergency braking light and the general warning triangle come on at times, and adaptive cruise control and lane departure warning or lane keeping assist stop working. Then they come back on their own.
Possible cause described
An internal control chip in the front camera (the one behind the interior mirror) fails and stores codes C1604-49 (hardware) or C1606-49 (software). Kia says to replace the camera (bulletin ELE231, April 2021, for Sportages built from May 2015 to September 2020 and Niros from April 2016 to September 2020).
Check for the garage
Clean the windscreen in front of the camera and note when it happens. At the garage, have them read the camera codes: with C1604-49 or C1606-49 the bulletin says to replace and calibrate it.
