Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“All passenger doors except driver door cannot be unlocked or opened using any method--the key or any unlock button, or using either inside or outside door handles. This leaves only the front driver door openable. This is a huge safety risk. I can't drive the car this way--I would not be able to get my kids out of the back seat. It happens whether the car is running or not, and moving or not.”
NHTSA complaint #11058203, filed 2018-01, 130,000 miles“Vehicle door locks do not properly function; I.e will not unlock by key fob. I have experienced this before and upon researching the incident, I determined this is a common fault by the manufacturer. Door will also remain locked while pushing the door unlock button located inside the vehicle. Doors will also remain locked when engaging the door handle from the inside (engaging door handle from the inside is supposed to unlock that door). This type of fault raises major safety concerns.”
