Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The passenger seat belt does not clip or will come undone at any given time. I made the dealership aware of the concern when the vehicle had approximately 39,000 miles. They stated that since it was out of warranty it did not qualify for production defect. This is a safety concern that could endanger the life of a person if west belt fails during a crash.”
