Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Bought a used car from a used car dealer with 1 previous owner. In 2011 a recall was supposedly done by indicating inspected! Why wasn't the parts replaced?”
NHTSA complaint #11102757, filed 2018-06, 204,000 miles“Running boards are completely rusted, they will either fall off while driving and could cause an accident or an unsuspecting person could be relying on them to enter the SUV and hurt them selves. The SUV was well taken care of, 1 owner, and the frame rails and chassis are considerably rust free. How come these are in such bad condition? Why don't Infiniti have replacements for them alone and not the whole running board for over $1300 per side! That's insane and no one is going to pay that for a 11+ year old SUV!”

I took it to a local service repair shop and they took off my left front tire and saw where my inner apron was severely corroded, cracked and perforated.they stated they never seen such a type of corrosion in this area and that I should have the manufacturer look at it and take it to a body shop. …”
