The facelifted fourth-generation TL arrived for 2012 retaining the core mechanical architecture of its predecessor: a 3.5-litre J35Y1 V6 driving the front wheels, or an authoritative 3.7-litre J37A5 paired with torque-vectoring SH-AWD on higher trims. These J-series engines are celebrated for mechanical robustness, but both utilise a rubber timing belt that must be renewed at 168,000 km or 7 years. Exceeding this limit brings severe risk of catastrophic engine failure. Drivers pairing spirited driving with motorway cruising report excellent long-term durability, provided regular Acura TL maintenance and oil changes every 8,000 km are never deferred.
