Three problems related to engine have been reported for the 1997 Toyota 4Runner. The most recently reported issues are listed below.
While driving on the highway at the speed limit (60 mph), the vehicle surged/jolted forward pulling to the right. I was unable to regain control of vehicle causing me to merge into the direction of a tractor trailer. I tried to turn away from tractor trailer to avoid collision. 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. My concern is regarding the periodic engine surge and/or jolting and lack of brake control. This is a safety hazard that must be addressed in order to avoid future incidents. We were very lucky to have not been killed in this auto accident.
Premature failure of head gaskets, Toyota refused to cover replacement.
Blown head gasket.
