Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“After driving the car, the right/left turn signal switch fails to work (no signal is given both in the panel of the car and the external turn signal lights do not flash). However, the emergency flashers still work. I have searched the issue and found many occurrences on the Internet. Such a common issue should be a manufacturing quality issue and deserves a recall.”
NHTSA complaint #11483939, filed 2022-09“Turn signals stop functioning during drive cycles. This functionality is lost for the remainder of the current drive cycle and can be restored with a key cycle. It does not occur every drive cycles and is unpredictable.”
