Acura vs Lexus Reliability: The Winner Isn't Even Close
Luxury sub-brands were a big thing in the 1980s. Honda got in first with its Acura brand in 1986. Offering solid reliability and affordable maintenance costs allied with an upmarket interior and plenty of kit, it was a popular alternative to the established luxury brands. Toyota soon joined the fray with its range of Lexus models in 1989, and before long the American and German luxury brands had a real fight on their hands to maintain market share.
While the competition between Lexus and Acura has certainly been strong over the years, they both aim at a slightly different target market. Consumers generally choose Acura for its blend of sharp handling, high-tech interiors, and sporty driving feel. On the other hand, Lexus has built its reputation on the core traits of refinement, comfort and understated luxury.
While both offer great products, we wanted to gauge just how reliable these models were when it came to reliability. With both parent companies priding themselves on building durable products, we looked to real owner reviews, courtesy of Consumer Reports, to see which one was the most reliable. With data derived from hundreds of thousands of real-world owner surveys, CR is the best source for unbiased reliability comparisons, and the results below are based on reliability trends and data for the 2023, 2024, and 2025 model years.
Compact SUVs: RDX vs. NX
- Lexus NX Reliability Score: 67/100
- Lexus NX base MSRP:$47,220
- Acura RDX Reliability Score: 52/100
- Acura RDX base MSRP:$44,700
The Lexus NX secures a solid reliability score in the compact SUV segment thanks to a well-developed platform that shares many core components with exiting Toyota models. The hybrid tech is as good as it gets in terms of durability, and few owners had major issues, with finicky wireless charging and infotainment gripes being the only notable problems. While not strictly a reliability issue, some owners found the touch-sensitive steering wheel controls to be a bit finicky.
The Acura RDX remains a favorite for driving enthusiasts, but its reliability score is hampered by recurring issues with its infotainment system. For the 2023 and 2024 models, many owners noted glitches with the True Touchpad Interface and occasional software freezes. While the engine and transmission have proven to be hardy, these electronic frustrations prevent it from catching up to the Lexus. The RDX is also due for replacement for the 2026 model year.
Midsize SUVs: MDX vs. RX
- Lexus RX Reliability Score: 69/100
- Lexus RX base MSRP:$52,375
- Acura MDX Reliability Score: 45/100
- Acura MDX base MSRP:$51,800
Lexus once again takes the win here. Even after a major redesign in 2023, the RX has maintained high scores throughout. Owners frequently praised the RX for its solid durability and the seamless operation of its hybrid systems. While it has moved away from the old V6 engine to a turbocharged four-cylinder, the transition has been remarkably smooth with very few reports of major mechanical failures.
The Acura MDX, while offering a more engaging drive and three rows of seating, has struggled with new-model teething issues. Reliability data indicates that owners of 2023 and 2024 MDX models have experienced problems with the 10-speed automatic transmission, specifically rough shifting at low speeds. Additionally, some owners have reported intermittent warnings on the digital dash, which has all contributed to the poor reliability score overall.
Midsize Sedans: Integra vs. IS
- Lexus Reliability Score: 79/100
- Lexus base MSRP:$46,895
- Acura Reliability Score: 47/100
- Acura Type base MSRP:$53,900
Due to the much smaller product offering from Acura (four vs 20+), we have matched up the Integra sports sedan with the Lexus IS. The IS is marketed as a more premium product, but these two overlap in overall dimensions and the range-topping Integra Type S rivals the IS in both power and performance figures, while costing a fair bit more. Base models are far less luxurious, but they offer serious value for money.
But when it comes to reliability, it's a much more one-sided affair. The Lexus IS is one of the highest-scoring vehicles in the entire Consumer Reports database. Part of its success is down to the extremely long production which started in 2013. There have been several major updates since, but the 3.5-liter V6 and eight-speed automatic transmission are as reliable as a sunset, and the rest of the package has been refined to iron out just about every major and minor issue.
The Acura Integra returned to the market in 2023, officially replacing the discontinued Acura ILX, and while it is a modern, very sporty liftback that is also more practical than the Lexus, it can't even come close to the IS for pure reliability. Owners of 2023 and 2024 Integras have reported minor build-quality issues, such as interior rattles and trim pieces that don't feel as premium as they should. The 1.5-liter turbocharged engine used in lower-spec versions has also had some issues, but these should have been resolved for the latest models.
The Integra is based on a newer platform than the aging IS, but it shares much of its componentry with the Honda Civic Si, and even that model scored a more respectable 59/100 over the same period. As it stands, if Acura is to truly challenge the dominance of Toyota in these market segments, it is going to need to put a lot more effort into upping the long-term reliability of its models.
