Reliability is front and center for car shoppers in 2026, especially in the luxury space. With prices climbing and depreciation hitting harder than ever, more buyers are planning to hang on to their cars instead of flipping them after a few years.
That makes long-term durability and resale value more important than badge prestige. What holds up well today is usually what holds its value tomorrow, and used buyers pay close attention to that.
According to J.D. Power’s latest study, the 2026 Lexus IS sits at the top of the dependability charts. Lexus has built its reputation on Toyota-based engineering with a premium twist, and the IS carries that formula better than anything else in the lineup.
In order to give you the most up-to-date and accurate information possible, the data used to compile this article was sourced from Lexus and other authoritative sources, including CarEdge, Edmunds, the EPA, iSeeCars, J.D. Power, and TopSpeed.

These Reliable Used Luxury Sedans Offer Proven Durability
If you’re after long-term dependability without giving up luxury, these pre-owned sedans stand out for their proven reliability and lasting quality.
Why the Lexus IS rises above the rest
The formula behind its long-term durability

For 2026, the IS 350 is now the starting point if you want a Lexus sedan with some real attitude. With the four-cylinder IS 300 gone and the V-8 IS 500 retired, the V-6-powered IS 350 is the only flavor left—and it carries the whole sporty sedan torch.
It slots in below the cushier ES and the big-body LS 500, but it’s playing a different game. While those two lean into quiet comfort and back-seat space, the refreshed IS sticks with its compact, rear-drive roots and keeps the focus squarely on driving.
What’s new for 2026

For 2026, Lexus trims the IS 350 lineup down to two core versions: F Sport Design and full-on F Sport. The look gets sharper too, with a lower, wider front end, a tweaked grille, fresh 19-inch wheels, a new rear spoiler, and new Wind and Neutrino Gray paint choices.
Inside is where the biggest changes happen. Every model now gets a 12.3-inch touchscreen and matching digital gauge cluster, plus a redesigned center console with wireless charging, four USB-C ports, and available Forged Bamboo trim.
The 311-horsepower 3.5-liter V-6 carries over, but Lexus didn’t leave the driving feel alone. A new electric power steering setup and revised dampers aim for smoother, more natural responses, and the car now comes standard with the latest Lexus Safety System+ 3.0 suite.

Topping the charts in J.D. Power’s latest study
What those dependability scores really mean

According to the 2026 J.D. Power U.S. Vehicle Dependability Study, the refreshed Lexus IS didn’t just do well—it came out on top. It was named the highest-ranked model overall in a year when dependability across the industry actually slipped.
That drop largely comes down to increasingly complicated tech and software headaches in newer vehicles. While some rivals chase bigger screens and flashier features, the IS quietly posted the lowest problem count of all 184 models evaluated, making it the clear durability standout for 2026.
The study looks at 2023 model-year vehicles after three years on the road, which makes the result even more telling. Luxury brands averaged 217 problems per 100 vehicles, while Lexus landed at just 151 PP100, with the IS benefiting from proven hardware and a no-drama engineering approach.
Why keeping it simple still works

The Lexus IS skips the over-the-top tech arms race, and some critics have called that a downside. But J.D. Power says nearly half of all reported problems come from glitchy infotainment systems and messy over-the-air updates, which suddenly makes that restraint look pretty smart.
Instead of chasing the latest software trends, the IS sticks with a setup that just works. That steady approach helped Lexus lock down the top premium brand spot for the fourth year in a row and turned the IS into something rare in today’s market.
The study shows gas-powered vehicles average 198 problems per 100 vehicles, and the IS comes in well below that mark. In a world obsessed with adding more screens and features, this sedan proves that sticking with proven hardware is still the best way to build something that lasts.

Edmunds estimates that owning a base rear-wheel-drive 2026 Lexus IS 350 will run about $72,112 over five years and 60,000 miles. Roughly $19,592 of that is depreciation, with $9,439 for maintenance, $1,087 for repairs, $17,377 for fuel, and $5,606 in taxes and fees.
Kelley Blue Book’s numbers are in the same ballpark, projecting $6,485 for maintenance and $1,189 for repairs over that same stretch. For a luxury compact sedan, those figures are surprisingly reasonable and reinforce the IS’s low-drama ownership story.
Lexus backs it up with a 4-year/50,000-mile basic warranty, a 6-year/70,000-mile powertrain warranty, and six years of corrosion coverage with unlimited miles. iSeeCars also estimates the IS 350 could last around 17 years or 184,046 miles, with a 40.3 percent chance of reaching 200,000 miles—impressive territory for anything wearing a luxury badge.
The IS has built a loyal following

The 2026 Lexus IS 350 remains a go-to pick in the U.S. luxury sport sedan crowd, and owners seem pretty happy about it. On Edmunds, it’s sitting at a solid 4.3 out of 5, with drivers frequently praising its build quality and no-nonsense reliability.
It’s also easier on the wallet than many of its direct rivals when it comes to upkeep. RepairPal estimates things like a stabilizer bar link kit at $185, spark plugs around $420, a fuel pressure sensor at $1,240, an exhaust manifold at $2,450, and stabilizer bushings at $1,120, while bigger jobs like a camshaft replacement can run about $3,200—not cheap, but reasonable for this class.

The bones may be familiar, but the 2026 IS 350 doesn’t feel dated once you’re inside. Lexus gave it a cleaner, more driver-focused layout, headlined by a standard 12.3-inch touchscreen and matching 12.3-inch digital gauge cluster running the latest Lexus Interface.
Wireless Apple CarPlay and Android Auto come standard, along with four USB-C ports and a 10-speaker Lexus Premium Sound system. Every model gets NuLuxe upholstery, dual-zone climate control, and a power tilt-and-telescopic steering wheel.
The F Sport Design, starting at $46,795, throws in heated front seats and now includes wireless charging as standard. Step up to the $49,245 F Sport, and you’ll also get ventilated seats, a heated steering wheel, and aluminum sport pedals for a more aggressive feel.
Dialing up the driving experience

If you want to dial things up a bit, Lexus offers a handful of worthwhile add-ons. The Technology Package layers in features like Traffic Jam Assist and a Panoramic View Monitor, while the F Sport Handling Package sharpens things up with adaptive suspension and a Torsen limited-slip rear differential.
Music lovers should look at the 17-speaker, 1,800-watt Mark Levinson system, which genuinely transforms the cabin into something closer to a rolling studio. There’s also a limited Special Appearance Package that bundles Hakugin Matte White paint, 19-inch BBS forged wheels, Triple-Beam LED headlights, and the Mark Levinson audio as standard, pushing the price to $61,385.
All-wheel drive will add $1,610 to the sticker, and every IS carries a $1,295 destination fee.
