Acura TSX CL9

The first-generation Acura TSX (CL9, 2004 to 2008) is essentially the European Honda Accord for North America, and that's exactly what makes it so likeable: a compact, well-balanced sport sedan with first-rate build quality, precise steering, and one of the best four-cylinders of its era. It was never the quickest car in its class, but the combination of driving pleasure, practicality, and exceptional reliability earned it a loyal reputation. On the used market, the CL9 is rightly regarded as one of the safest bets you can make.

At its heart is the 2.4-liter i-VTEC (K24), one of the most robust four-cylinders ever made, easily clearing 300,000 miles with regular oil changes. Its only real Achilles' heel is the oil-controlled timing chain and VTC actuator: if oil changes are neglected, the VTC actuator rattles mainly on cold starts, and over the long run the timing chain can stretch while the tensioner wears. Anyone running clean oil at the correct interval keeps these problems small. Slightly elevated oil consumption from piston-ring wear and some exhaust-camshaft wear are possible at higher mileage, along with worn engine mounts causing noticeable vibration. Overall, this engine gets an unqualified recommendation.

Among the vehicle-level issues there are a few known points. The A/C compressor can shatter internally, spreading metal debris throughout the refrigerant circuit and taking out the condenser, drier, and valves, which makes the repair expensive. A recall covered the power-steering hose, which ages and can rupture in the high underhood temperatures, dripping fluid onto the exhaust. The most common TSX-specific annoyance is the door-lock actuators, which fail as sealed, non-repairable units, often both fronts in short succession. There was also a recall for an engine control unit that can corrode from moisture, for which the dealer fits a water-repellent cover.

Bottom line, the CL9 is a thoroughly recommendable used car that blends reliability and driving fun in a rare way. When buying, prioritize a complete oil-change record, an ear for VTC rattle on cold start, a test of the door locks and air conditioning, and confirmation that the recalls have been done. The manual is the ideal pick, though the automatic in the CL9 is sturdier than in some sister models. A well-kept example is a long-lived, unfussy companion that still impresses today.
