Highlander 4-cyl

  • 148,500 miles
Needed to have a total engine rebuild due to faulty head bolts that stripped and allowed coolant to enter the engine and burn. Lucky-I guess-that I acted quickly so as to avert catalytic converter issues or sensors getting damaged by burning coolant. I also avoided the total loss of antifreeze and the resulting damage &/or inconvenience that thousands of others had. Still, a huge inconvenience and huge $5425.82 cost due to manufacturer's defect: Weak metal that couldn't withstand the torque/pull on them... perhaps the threading played a part. I only know that 1000S upon 1000S of people suffered the same issue from Toyota on this engine in several years/models. There should be a recall. There should be compensation.
