Reliability isn’t just a badge. It’s math. J.D. Power says Lexus still dominates the premium sector. The data backs the reputation.
But here is the catch.
Not every model earns its keep equally. Some ride on ancient, bulletproof engineering. Others are fresh toys with tech that hasn’t aged in. We looked at the scores. From the unproven to the invincible.
The Unrated: Waiting For Data
2026 Lexus RZ
- Reliability Score: Not Rated
This is Lexus’ first proper EV SUV. It looks futuristic. The e-TNGA platform is shiny, new, and sleek. Inside? Minimalist. Quiet.
In the U.S., you get the RZ 300e (201 hp, front-wheel drive) or the 450e AWD model (308 hp). Range sits between 220 and 30 miles depending on wheels and trim.
New car. No long-term scars yet. Consumer Reports thinks it will be above average. Lexus engineering is solid, but time will tell.
Worst Year Used: 2023. Software bugs plagues launch years.
Maintenance: Below average expected. Recalls: 1.
2026 Lexus LS
- Reliability Score: Not Rated
The flagship sedan. Peak luxury. A 3.4-liter twin-turb V6 pushes out 416 hp and 442 lb-ft of torque. Effortless.
It fights the Mercedes S-Class and BMW 7 Series for prestige. Those rivals are complex beasts. The LS? Lexus built it with conservative engineering in mind. Durability over drama.
It costs more to keep, sure. Around $870 a year. But compared to German alternatives, the stress level drops.
10-Year Maintenance: ~$9,500
Total Recalls: 4
Worst Year Used: 2007. Air suspension and electronics nightmares.
2026 Lexus GX
- Reliability Score: Not Rated
The body-on-frame tank returns. Updated look. Same rugged soul.
The new twin-turbo 3.4L V6 makes 349 hp. Off-road capability is serious. On-road manners are better than before. It aims at the Defender and Land Cruiser but promises lower ownership headaches.
Data is thin. The Toyota bloodline is thick though. This will likely be tough. Very tough.
10-Year Maintenance: ~$8,500
Total Recalls: 3
Worst Year Used: 2004. Secondary air injection failures.
The Mid-Tier: Proven, But Complex
2026 Lexus UX
- Reliability Score: 80/100
Small. Efficient. Urban.
Most get the 2.0L hybrid (181 hp combined). Not fast. Very smooth. It beats the Volvo XC40 on dependability even if the Volvo has more go-fast. The build quality inside is high for the class.
10-Year Maintenance: ~$6,500
Total Recalls: 1
Worst Year Used: 2019. Electrical gremlins.
2026 Lexus TX
- Reliability Score: 80/100
Three rows. Family duty.
The non-hybrid TX 350 has a turbo-four (275 hp). The Hybrid TX 500h gets 366 hp combined. It is about space, not sport. It sits against the Acura MDX and Q7.
Early data is okay. It’s new. Trust is earned slowly.
10-Year Maintenance: ~$7,500
Total Recalls: 2
Worst Year Used: 2024. Always a risk buying year one.
2026 Lexus RX
- Reliability Score: 82/100
The best seller. The staple.
Turbo engines and hybrids dominate. The RX 500h delivers 366 hp. It fights the X5 and GLE but wins on smoothness.
It has consistent top-tier scores in J.D. Power and Consumer reports. The oil cooler issues from the past have largely been resolved, but the reputation stands firm.
10-Year Maintenance: $7,500 – $8,000
Total Recalls: 5
Worst Year Used: 2007. Oil cooler line failures.
2026 Lexus NX
- Reliability Score: 85/100
Bold looks. Many choices.
Engines range from a basic 4-cylinder (203 hp) to a turbo (275 hp) and various hybrid setups. The BMW X3 might be more exciting. The NX is less complex underneath than its rivals.
Complexity breeds failure. The NX balances modern tech with established reliability foundations.
10-Year Maintenance: ~$7,712
Total Recalls: 4
Worst Year Used: 2015. Early infotainment and transmission pain.
The Top Dogs: Set It And Forget It
2025 Lexus ES
- Reliability Score: 89/100
Safe bet. Extremely safe bet.
Forget driving dynamics. This car is about comfort and silence. A 2.5L engine (203 hp), a V6 (302 hp), or a hybrid. All prioritize efficiency over adrenaline.
The Acura TLX tries harder. The ES lasts longer. Simplicity is king here. The dashboard melting issue is ancient history now, but it haunts the used market.
10-Year Maintenance: ~$5,945
Total Recalls: 3
Worst Year Used: 2007. Dashboard melt and oil lines.
2026 Lexus IS
- Reliability Score: 91/100
The most dependable sports sedan in the group.
Only one choice for 2026: 3.5L naturally aspirated V6. 311 hp. No turbo lag. No complicated electronics masquerading as performance.
While the BMW 3 Series gets denser and more digital, the IS stays mechanical. Simple engines don’t have as many things to break.
10-Year Maintenance: ~$6,000
Total Recalls: 2
Worst Year Used: 2007. That dashboard thing again.
What Actually Matters
The pattern is clear. Proven platforms beat new ones. Simpler powertrains live longer than complex electrified setups, mostly.
Lexus hybrids are exceptions. They are among the most robust electrified systems out there. Even the “worse” ranked models here outpace most luxury competitors.
Want zero headaches? Get the ES or RX. Need a tank? The GX delivers.
New cars like the RZ have promise. But promise isn’t a history book. They need time.
Lexus doesn’t win by inventing new trends. It wins by fixing old ones and keeping them running. Is that boring? Maybe. Does it pay the bills when nothing else is broken?
Yes.
