Is a 2004 Acura TL a reliable car?
Yes — with proper maintenance and a solid service history, a 2004 Acura TL can still be a reliable daily driver.
As a mid-2000s luxury-sport sedan, the TL benefited from dependable engineering and widely available parts, but its age means that wear-and-tear from higher mileage and long-term use will influence reliability. A careful evaluation of maintenance records, current condition, and the cost of impending repairs is essential for anyone considering one today.
How reliability stacks up for the 2004 TL
The 2004 TL sits in Acura’s second-generation lineup, known for solid build quality, comfortable ride, and durable powertrains. The model typically pairs a V6 powertrain with a drivetrain that, when properly serviced, has a reputation for longevity. Because the car is now two decades old, reliability hinges on maintenance history, mileage, and how well previous owners cared for components like the cooling system, suspension, and transmission.
Key reliability strengths
These factors help explain why the 2004 TL maintains a positive reputation among used-car shoppers:
- Durable V6 powertrain with long service life when regularly serviced
- Robust engineering and solid chassis design that ages well with proper maintenance
- Wide availability of replacement parts and access to knowledgeable technicians
- Comfortable ride quality and interior durability that hold up in older vehicles
Overall, these strengths contribute to a favorable reliability profile for well-maintained examples.
Common issues to watch in older TLs
Engine and powertrain
Before inspecting the list, note that aging engines and transmissions can develop wear that affects reliability. Be prepared to assess these typical areas:
- Cooling system wear, including hoses, radiator, and water pump seals
- Engine oil consumption and leaks, particularly around gaskets and seals
- Transmission wear or rough shifting in higher-mileage cars
- Timing chain guides and tensioners (the J-series engines use a chain, which reduces, but does not eliminate, maintenance needs)
With a comprehensive inspection and documented maintenance history, many of these concerns can be managed effectively.
Suspension, brakes, and electrical components
The following items commonly show aging in taller-mileage TLs and can impact reliability and drive experience:
- Worn suspension components (struts, bushings, control arms) affecting ride and handling
- Brake system wear and potential rotor rust in cars with inconsistent use
- Electrical issues such as window regulators, switches, and instrument cluster glitches
- HVAC system performance and potential compressor or sensor-related faults
A thorough pre-purchase check can identify these problems before they become costly repairs.
Owning costs and maintenance expectations
Owning a 2004 TL entails ongoing maintenance and the possibility of age-related repairs. Here’s what drivers typically plan for over time:
- Regular maintenance costs: routine oil changes, fluids, filters, and belt/sensor checks
- Tires and brakes: replacement costs that increase with mileage and driving style
- Major repairs: potential transmission service, cooling-system work, or suspension overhauls at higher mileages
- Fuel economy: average levels typical for a mid-2000s V6 sedan, varying with driving conditions
- Insurance and registration: generally reasonable for an older car, but parts availability can influence repair costs
With proactive maintenance and a conservative replacement schedule for aging parts, ownership costs can be predictable for many years.
What to check before buying a used 2004 TL
A thorough pre-purchase inspection helps mitigate risk when buying an aging TL. Focus on these checks and tests:
- Complete service history and mileage transparency
- Engine start and idle quality; listen for unusual noises
- Cooling system condition and evidence of leaks or overheating
- Suspension wear and steering responsiveness
- Electrical systems, including windows, lights, climate control, and gauges
End-to-end evaluation by a qualified mechanic can reveal hidden issues and provide a repair timeline and cost estimate, helping you decide if a particular TL is worth pursuing.
Summary
The 2004 Acura TL remains a compelling used-car option for buyers who value reliability, a solid drivetrain, and comfortable daily usability. Its two-decade age means condition varies widely, so a meticulous inspection and complete service history are essential. If the car has been well cared for and mileage is reasonable for its age, a TL can deliver dependable transportation for years to come—with attention to aging components and prudent maintenance budgeting.

The 2004 Acura TL receives an average consumer rating of 4.8 overall and a 4.8 for reliability, which means owners consider its reliability to be above average.
What year is the most reliable Acura TL?
The most reliable Acura TL years are generally considered to be from 2008-2009 and 2012-2014, as these models consistently receive high reliability ratings from sources like Forbes, Consumer Reports, and J.D. Power. The 3rd generation (2004-2008), especially with a manual transmission, is also a solid option, though the early years of this generation had potential automatic transmission issues.
Most reliable years
- 2008-2009: Both years received high grades for long-term durability and dependability. The 2008 model featured a choice of a 3.2-liter or 3.5-liter V6, and the 2009 model was redesigned with a 3.5-liter V6 for the base engine or a 3.7-liter V6 for the SH-AWD model.
- 2012-2014: These model years are highlighted for having very few issues, with the 2014 model having a high reliability rating from RepairPal.
- 2010-2015: This entire range is often cited as having improved reliability and refined designs. However, be aware that the 2010 model is sometimes cited as having more complaints than other years in this range, specifically related to engine oil consumption, according to CarParts.com.
Other years to consider
- 2004-2008 (3rd Gen): This generation is considered reliable, particularly if you choose the manual transmission, which is more reliable than the early automatic transmissions, note Reddit users.
- 2006: This model year received high reliability ratings and is praised by owners for its dependability and power.
Years to approach with caution
- 2000-2003 (2nd Gen): These years are prone to automatic transmission issues.
