Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“First, the rubber hatch release melted & dripped onto my rear bumper. (I suspect that faulty wiring of some sort kept the release somewhat engaged, which melted the rubber.) then the hatch latch/lock would only completely release after multiple attempts. Finally, after unlocking the hatch & engaging (I thought) the release, the entire panel pulled off the car, leaving it dangling by the wiring harness.”
