A midsize luxury sport sedan with a gas powertrain. Below: the service intervals with real cost ranges, the repairs TLX owners actually report, and when a fleet operator would sell. Same data Carlyle uses to score fleet buys.

Operator notes
Timing CHAIN. Base = 2.0T K20C + 10AT; Type S = 3.0L turbo V6 + 10AT + SH-AWD. Direct-injected turbos - shorten oil to ~5,000 mi in cold/short-trip use. SH-AWD needs rear-diff/transfer-case service. 2nd gen (2021-2025); DISCONTINUED after MY2025 as Acura shifts to SUVs/EVs.
