The 2010 Acura TSX is one of the more reliable used entry-level luxury sedans from its era. Built around proven Honda engineering, it combines good fuel economy, responsive handling, a well-finished interior, and powertrains capable of very high mileage. A properly maintained 2010 TSX can realistically exceed 200,000 miles, and exceptionally well-maintained examples can travel considerably farther.
The standard engine is a naturally aspirated 2.4-liter four-cylinder from Honda's well-regarded K-series engine family. It is generally the best choice for buyers primarily concerned with reliability and ownership costs. The engine uses a timing chain rather than a timing belt and has relatively few serious inherent weaknesses when oil changes and other routine maintenance are performed on schedule.
For 2010, Acura also offered a more powerful 3.5-liter V6. The V6 provides substantially stronger acceleration and makes the TSX feel more like a traditional luxury sport sedan, but it also increases fuel consumption and maintenance costs. Unlike the four-cylinder, the V6 uses a timing belt that must be replaced at the recommended interval along with related components such as the water pump.
Transmission reliability is generally good. Four-cylinder models were available with a six-speed manual or five-speed automatic transmission, while the V6 came with the automatic. The manual is particularly durable, while the automatic can also provide long service life when its fluid has been changed periodically with the proper Honda/Acura fluid.
The rest of the TSX generally ages well. Suspension components, engine mounts, wheel bearings, air conditioning equipment, and various electrical accessories may require attention as mileage increases, but these are typically age-related repairs rather than fundamental flaws in the vehicle. Parts availability is also good because many mechanical components are related to other Honda and Acura products.
Overall, the 2010 TSX is an above-average choice for someone shopping for an older premium sedan. It doesn't have the rear-wheel-drive dynamics of a BMW 3 Series, but it generally requires fewer expensive repairs and can be considerably easier to own as mileage increases.
- Overall reliability: Above Average to Excellent
- Expected lifespan: 225,000 to 300,000+ miles with proper maintenance
- Best choice: 2.4-liter four-cylinder with documented maintenance records
- Watch for: Oil consumption, transmission maintenance, suspension wear, engine mounts, and V6 timing belt history
Bottom line: The 2010 Acura TSX is one of the safer choices among older luxury-brand sedans. The 2.4-liter four-cylinder is particularly appealing because it combines excellent durability with reasonable fuel and maintenance costs. Find a clean example with a good service history and it can remain dependable well beyond 200,000 miles.
- Why it's a good choice: Proven Honda powertrains, excellent build quality, good fuel economy, strong resale value, and relatively manageable repair costs
- Biggest concern: Age-related maintenance and evidence that previous owners kept up with fluid changes and other scheduled services
- Best version: 2.4-liter four-cylinder with complete service records
- Buy only if: The engine runs smoothly, the transmission operates properly, maintenance can be verified, and the vehicle passes a pre-purchase inspection
Is the 2010 Acura TSX a Good Year or One to Avoid?
The 2010 Acura TSX is generally a good year to buy rather than one to avoid. It was the second model year of the second-generation TSX, and its core mechanical components are based on proven Honda designs. There is no single widespread mechanical defect that makes the 2010 model inherently undesirable.
For buyers interested primarily in long-term reliability, the 2.4-liter four-cylinder is the standout. It offers enough performance for normal driving while avoiding the timing belt maintenance and additional fuel consumption of the V6. A six-speed manual four-cylinder can be particularly durable, although clean manual-transmission examples are increasingly difficult to find.
The 3.5-liter V6 shouldn't automatically be avoided. It's a strong and generally dependable engine, but buyers should verify timing belt maintenance and understand that fuel, tire, and other operating costs may be somewhat higher. At this age, maintenance history matters considerably more than whether the odometer shows 90,000 or 130,000 miles.
Buyer Takeaway: The 2010 TSX is a good used-car choice, particularly with the 2.4-liter four-cylinder. I'd favor a higher-mileage example with excellent service documentation over a lower-mileage car with an uncertain history. There are few reasons to take a chance on a neglected TSX when well-maintained examples can be exceptionally durable.

2010 Acura TSX Common Mechanical Problems
The 2010 Acura TSX has relatively few serious mechanical weaknesses, which is one reason it remains an appealing older used car. Most problems involve oil consumption, suspension components, engine mounts, accessories, or other parts that naturally wear as a vehicle approaches 150,000 to 200,000 miles.
- Oil consumption: Some 2.4-liter four-cylinder engines can begin consuming more oil as mileage increases. Buyers should check the oil level before starting the car and ask the owner how frequently oil needs to be added between changes. Moderate consumption can often be managed, but an engine that has repeatedly been operated with a low oil level is a much greater concern.
- Engine oil leaks: Valve cover gaskets, timing cover areas, and other seals can begin seeping oil with age. Minor leakage isn't unusual on a 15-year-old vehicle, but significant leaks should be factored into the purchase price. Look underneath the engine and check for a burning-oil smell after driving.
- Automatic transmission shift quality: The five-speed automatic is generally durable, but neglected fluid changes can eventually contribute to harsh shifts, hesitation, or shuddering. The transmission should shift smoothly both when cold and after reaching operating temperature. Documented fluid changes using the proper Honda/Acura fluid are a significant plus.
- V6 timing belt maintenance: The 3.5-liter V6 uses a timing belt rather than the timing chain found on the four-cylinder. If there is no documentation showing that the belt has been replaced at the appropriate mileage and age interval, assume the service may be due and include the cost in your purchase decision. The water pump and related components are commonly replaced at the same time.
- Engine mount deterioration: Worn engine mounts can cause noticeable vibration through the steering wheel, seats, or dashboard while idling, especially with the automatic transmission in Drive. This isn't usually a reason to reject the car, but replacing multiple mounts can become relatively expensive.
- Suspension wear: Struts, shocks, control arm bushings, ball joints, and sway bar links eventually wear as mileage increases. Listen for clunks over rough pavement and look for uneven tire wear. A TSX should still feel tight and controlled rather than loose or excessively bouncy.
- Wheel bearing wear: Worn wheel bearings can create a humming or growling noise that increases with road speed. The sound may change when the vehicle is gently steered from side to side. Replacement is a normal higher-mileage repair but should be considered when negotiating the price.
- Power steering concerns: Steering components and related electrical or mechanical parts can develop problems with age. Pay attention to unusual noises, warning lights, inconsistent steering effort, or looseness during the test drive.
- Air conditioning problems: Compressors, relays, condensers, and other climate-control components may eventually require repair. Run the air conditioning long enough to verify that it continues blowing cold rather than simply checking it immediately after startup.
- Starter and alternator wear: These components can eventually fail simply because of age and mileage. Slow cranking, charging-system warnings, dimming lights, or an aging battery can indicate that diagnosis is needed.
- Electrical accessories: Door lock actuators, power seat controls, window components, navigation equipment, Bluetooth systems, and audio electronics can develop faults over time. Test every electrical feature before buying because individual repairs can add up quickly.
- Brake and caliper problems: Older TSX models may develop sticking brake calipers or uneven brake wear. During the test drive, check for pulling, vibration, unusual heat from one wheel, or a burning smell after braking.
One of the TSX's biggest advantages is what's largely absent from this list: widespread catastrophic engine or transmission failures. A vehicle needing struts, an engine mount, or an air conditioning repair may still be an excellent purchase if the underlying engine, transmission, and body are in good condition.
Buyer Tip: Check the engine oil before starting the car, listen carefully during a cold start, and drive long enough to evaluate the automatic transmission after it has warmed up. On a V6, ask specifically for documentation of timing belt replacement. A four-cylinder TSX with regular oil changes, documented transmission service, and no evidence of excessive oil consumption is particularly desirable.
2010 Acura TSX Pros and Cons
The 2010 TSX occupies an interesting position in the used-car market. It offers many of the features and refinement associated with a luxury sedan while retaining much of the mechanical durability and relatively reasonable ownership costs associated with Honda. That makes it particularly attractive to buyers who want something more upscale than an Accord without taking on the potential repair costs of an older European luxury car.
Pros
- Excellent four-cylinder reliability: The 2.4-liter four-cylinder is a proven engine capable of very high mileage when properly maintained.
- Long potential lifespan: Well-maintained TSX models can realistically remain useful beyond 200,000 miles, and exceptionally good examples can approach or exceed 300,000 miles.
- Reasonable ownership costs: Although it's an Acura, many routine maintenance and repair expenses are considerably more manageable than those associated with German luxury sedans of the same age.
- Good fuel economy: The four-cylinder provides respectable fuel economy while still delivering enough power for everyday driving and highway use.
- Excellent interior quality: Acura used durable materials, and well-cared-for interiors often hold up remarkably well even at higher mileage.
- Enjoyable handling: Responsive steering and a well-controlled suspension make the TSX more engaging to drive than many mainstream midsize sedans.
- Available manual transmission: The six-speed manual is both enjoyable and durable, making it particularly attractive to enthusiasts who want a reliable sport sedan.
- Good parts availability: Honda/Acura's large dealer and independent repair network makes servicing an older TSX relatively straightforward.
Cons
- Oil consumption is worth monitoring: Some four-cylinder engines begin using noticeable amounts of oil at higher mileage, making regular oil-level checks important.
- V6 requires timing belt service: The more powerful engine adds an important scheduled maintenance expense that the timing-chain-equipped four-cylinder doesn't have.
- Premium fuel is recommended: Fuel costs can be somewhat higher than those of mainstream midsize sedans designed to run on regular gasoline.
- Rear-seat space is only average: Buyers prioritizing maximum family room may find an Accord, Camry, or larger sedan more accommodating.
- Ride is relatively firm: The TSX's handling-oriented suspension can transmit more bumps and road imperfections than softer midsize sedans.
- Luxury electronics can be expensive: Navigation, audio, seat, climate-control, and other electronic equipment can cost more to repair than basic mechanical components.
- Clean examples can command a premium: Acura's reputation for reliability means well-maintained, lower-mileage TSX models sometimes sell for surprisingly strong prices.
- Age-related repairs still matter: Acura reliability doesn't eliminate the effects of age. Rubber bushings, mounts, seals, suspension parts, and accessories can all need replacement on a vehicle this old.
Buyer Takeaway: The 2010 Acura TSX is one of the better choices for someone who wants an affordable older luxury sedan without assuming unusually high repair risk. For maximum reliability and lower ownership costs, I'd favor the 2.4-liter four-cylinder with documented maintenance. The V6 is worthwhile for buyers who value stronger acceleration and don't mind additional fuel and maintenance expenses. Either way, a clean TSX with a strong service history can be a considerably safer long-term bet than many similarly priced luxury sedans.
