NHTSA Complaint #11442992 — 2016 MAZDA CX-5

2016 Mazda CX-5 windshield wipers - Correctly operating windshield wipers have four modes: single wipe, intermittent wipe, slow continuous wipe, high speed continuous wipe. One morning (September, 2021) used the single wipe mode to clear overnight accumulated moisture (car parked outside) but wiper made five passes instead of one and then stopped in an 'up' or 'non-parked' position. Tried the other three modes and all three behaved the same way, five wiper passes and then the wipers stopped, sometimes upright blocking forward vision, sometimes at an angle, but never in the 'parked' position. Driving in rain or snow requires activating the wipers every 30 seconds or so (approximate time of 5 wipes). Have had the wiper motor (which includes a circuit board) replaced twice to no avail. Today had wiper switch replaced, again to no avail. This problem seems to be similar to windshield wiper problem reported regarding 2016-2018 Mazda CX-3's.
