Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“This morning when I got in my truck, I noticed the dashboard by the passenger side airbag had cracked overnight. The weather hasn't been too hot or cold. Days in lower 90s and lows in upper 70s. I have read this is a common issue and I am afraid an airbag deployment will launch plastic pieces through the cabin.”
