“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. Other cars in the Toyota line have same problem and they are fixing the engine for free, but not the 4 RUNNER. They have 3 models that are doing the same thing, the engine are slugging up and cause engine failure. They said this model does not fall in that line, and will cost me $9,000 to fix, but first they quote me $5000. The oil has been changed every 3000 miles or so, not all by the dealer. …”

My vehicle hit the rear tire of the tractor trailer and I began to swerve out of control. My brakes didn't seem to help either, they didn't function. This resulted in the vehicle rolling over 3+ times, the car was totaled. All passengers were hospitalized but no other vehicles or people were hurt from the accident. …”
