Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The dashboard has substantial cracking. The vehicle has been garage kept and has not had any chemicals used to clean the dashboard since it was purchased new. I'm worried about the effectiveness of the airbags if they were to come into contact with the sharp plastic edges of the cracks when they deploy. I'm also concerned about broken plastic pieces becoming airborne in the cab in the event of an accident, as I usually have my 3 young children in the back seat.”
