Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The vehicle had a bad muffler in it so I took into to the muffler shop and as they fixed the muffler they found that the entire frame of the car is rusted out. There are several holes in the frame. I drive my children in this car everyday ( 4 years old and 1 year old) car is not safe and I am currently out a vehicle and cannot afford another one. Still trying to figure out a solution. The entire frame is damaged.”
NHTSA complaint #10572601, filed 2014-03, 177,000 miles“Engine stop running, because of slug build up in 4 RUNNER engine 1997.
