Frequent problems
The 3UZ engine corresponds to the family of its predecessors and also does not show even minor flaws, subject to regular maintenance and high-quality fuel and lubricants. The motor is very reliable and durable. The developers have tried so much that neither the entire engine as a whole, nor its individual units have any serious design flaws or errors. For this reason, accident-free engine mileage of 500 thousand km or more is far from uncommon among responsible car owners.
