You are confusing deaths with actual instances. Even if nobody died due to the rollover it still causes damage to the actual vehicle and to the property it rolls on.
These are the facts:
2019 TOYOTA 4RUNNER SUV AWD | NHTSA
That is regarding the 2019 model but Toyota has made no updates for 2020, 2021, or beyond in trying to fix this issue.
Yes any car, especially with a high center of gravity can rollover but in reality, there will be situations where a driver may have to take evasive action to prevent a greater accident. If that evasive action results in a rollover, then it isn't a good vehicle. Or even making any minor contact with a curb causes it rollover isn't good either.
The NHTSA has no reason to lie considering there are tons of American cars on that list which one expects due to the American lack of safety but Toyota is supposed to be all about safety. Remember they exposed the Ford Pinto so they have nothing to gain by saying 4runners rollover.
For a vehicle almost $50,000(TRD Pro), it should NOT have any rollover issue.
