Toyota Camry XV50

2.5-litre four-cylinder fitted in the mid-size class and in compact SUVs, valued for its smoothness and economy. The known weakness is elevated oil consumption from low-tension piston rings, for which the maker issued a technical service bulletin and settled a class action. Early years show a documented camshaft-gear rattle on cold start. The water pump with its plastic impeller wears out and should be checked for leaks when buying, as should the oil level. Overall, once warranty repairs have been done, it is a solid, durable engine.

3.5-litre V6 — Toyota's universal six-cylinder from midsize cars up to SUVs, balanced between smoothness and durability. Timing chain, maintenance-free. The cam tower oil leak occurs as on the big V8 but less often; on early build years also watch for leaking intake-manifold hoses. Budget for a water pump from around 130,000 km — it often signals itself with a light coolant weep. Oil changes every 10,000 to 15,000 km. Overall one of the most reliable V6s on the market, with documented lifespans past 400,000 km.
