Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I had the rear defrost running, and began to hear a sizzling/hissing sound in the back seat. After a minute of hearing this noise, I noticed smoke coming from the rear sliding window. I immediately turned off the rear defrost. A few seconds later, I heard a loud pop and the passenger side of my rear window was shattered. I called and spoke with the dealership and explained what had happened. They said they knew exactly what had happened and it is pretty common in these trucks.”

NHTSA complaint #11450594, filed 2022-02
