If you’re eyeing a 2024 Lexus RZ, you’re probably wondering whether this sleek electric SUV is as bulletproof as the brand’s gas models, or if you’re signing up to be a beta tester for Lexus’s first ground‑up EV. The short answer: the 2024 Lexus RZ’s reliability is shaping up as above average for an EV, but it has a few early‑generation wrinkles you should know about, including a recall and some software‑centric complaints.
Big picture on 2024 Lexus RZ reliability
2024 Lexus RZ reliability at a glance
Where the 2024 Lexus RZ stands today
Because the 2024 RZ is still a relatively new model, we don’t yet have a decade of hard data the way we do for a Lexus RX or ES. What we do have are brand‑level reliability scores, an early recall campaign, and owner reports that show the pattern forming: electronics and HVAC glitches matter more here than traditional mechanical failures.
How reliable is Lexus as a brand?
Before you zoom in on the RZ, it helps to zoom out. Lexus hasn’t just been “pretty good” on reliability, it’s been the benchmark. Recent studies from J.D. Power’s Vehicle Dependability Study and Initial Quality Study, along with Consumer Reports’ brand rankings, repeatedly place Lexus at or near the top for fewest problems per 100 vehicles. In several model years running, Lexus has scored better than every other premium brand and most mainstream brands, too.
- Lexus typically posts the lowest problems per 100 vehicles (PP100) in J.D. Power dependability rankings, meaning fewer owner‑reported issues over 3 years.
- Consumer Reports’ brand reliability tables consistently keep Lexus in the top tier, alongside Toyota and Subaru.
- Owner surveys and long‑term tests routinely praise Lexus for quiet durability and low repair rates, especially on proven platforms like the RX and ES.
That matters because the RZ is Lexus’s first mass‑market EV, and the company has taken a conservative approach: familiar interior hardware, relatively modest battery size, and powertrains that are more about smoothness than shock‑and‑awe. All of that tends to help reliability, not hurt it.
Shared DNA with Toyota bZ4X and Subaru Solterra
Under the skin, the 2024 Lexus RZ shares its e‑TNGA architecture and many components with the Toyota bZ4X and Subaru Solterra. That’s good news and bad news.
Why shared parts help reliability
- More vehicles testing the same hardware means issues surface quickly and fixes arrive faster.
- Toyota and Subaru bring a long history of durable powertrains and conservative tuning.
- Parts and service procedures are broadly shared, so dealer techs see these systems more often.
Where it introduces risk
- Any platform‑level defect, like a software bug, can hit all three models at once.
- The bZ4X and Solterra had early‑run issues, including recalls, that spill over to the RZ.
- Because this is Toyota Group’s first modern EV platform, some debugging is inevitable in the first years.

Known 2024 Lexus RZ issues and recalls
No EV is perfect, and the 2024 Lexus RZ is no exception. The good news is that, so far, its problems are largely in the **software and climate‑control** bucket, not catastrophic battery or motor failures.
Common 2024 Lexus RZ issues reported so far
What we’re seeing across owner reports, recall information, and platform‑shared problems.
| Issue | How it shows up | How serious is it? | What fixes it? |
|---|---|---|---|
| Defroster / HVAC recall | Weak windshield defogging in cold or damp weather; may feel like the heat never really kicks in. | Moderate safety concern in winter climates; covered by recall. | Dealer software update for the HVAC control module; compressor replacement in a minority of cases. |
| Software / infotainment glitches | Frozen screen, slow boot‑up, random reboots, Bluetooth drops. | Annoying more than dangerous, but can undermine the premium feel. | Software updates from Lexus (over‑the‑air where available) or dealer flash. |
| Charging quirks at public stations | Occasional failure to start a DC fast‑charge session on the first try, or charge rate slower than expected. | Mild to moderate inconvenience on road trips; usually fine at home. | Unplug/restart session, try another charger; look for firmware updates for the car and the station network. |
| Wind / road noise complaints | Some owners note more wind noise than expected at highway speed versus a Lexus RX. | Comfort issue, not a failure; doesn’t signal a mechanical problem. | Weather‑strip adjustments, different tires, or simply a realistic expectation reset for a tall EV SUV. |
Issue frequency varies by vehicle and build date. A pre‑purchase inspection can help you separate one‑off glitches from patterns.
About that HVAC/defroster recall
Battery life, range, and charging reliability
When shoppers ask about 2024 Lexus RZ reliability, much of what they’re really asking is, “Will the battery hold up?” and “Will this thing charge when I need it to?” On both counts, the RZ is trending the way you’d expect from Lexus: conservative but confidence‑inspiring.
- Lexus typically backs its EV battery for at least 8 years or a high‑mileage cap against defects and excessive capacity loss (check your specific warranty booklet for the exact numbers in your market).
- The RZ’s battery chemistry is tuned more for longevity and consistent performance than for headline‑grabbing range numbers, which should help reduce long‑term degradation.
- Real‑world range reports generally land a bit below the EPA estimate, especially at highway speeds and in cold weather, but owners aren’t seeing sudden, dramatic loss of range in the first couple of years.
Battery‑friendly habits for your RZ
Home charging reliability
At home, the RZ is a drama‑free roommate. On a quality Level 2 charger, most owners report consistent overnight charging with no interruptions and predictable range each morning.
- Use a properly installed 240V circuit and reputable charger.
- Keep your charging cable and port clean and dry.
- If you live in an older home, have an electrician confirm the circuit is truly up to the task.
Public charging reliability
On DC fast chargers, the RZ behaves a lot like its bZ4X and Solterra cousins: mostly fine, but the weak link is often the station, not the car.
- Be prepared for the occasional failed handshake; unplug and try again or move to another stall.
- Don’t rely on arriving nearly empty, plan a buffer of 15–20% in case a station is offline.
- Check recent user check‑ins in apps like PlugShare to avoid problem stations.
What early owners are reporting
Owner forums, early reviews, and service data so far paint a familiar Lexus‑but‑EV picture: very few tow‑truck stories, lots of minor software annoyances. Compared with some rival EVs, the RZ seems to have avoided the nightmare scenarios, think repeated 12‑volt battery failures, dead‑on‑arrival drive units, or widespread water leaks.

Tech quirks
The mechanical bits of the RZ feel exactly like what you’d expect from Lexus, overbuilt and unbothered. It’s the software and charging ecosystem that still feel more 2020s than timeless.
2024 Lexus RZ reliability vs rival EV SUVs
If you’re cross‑shopping the RZ with a Tesla Model Y, Genesis GV60, Mercedes‑Benz EQE SUV, or a mainstream EV like the Hyundai Ioniq 5 or Kia EV6, you’re really comparing two things: the brand’s track record and this generation of EV hardware.
How the 2024 Lexus RZ stacks up on reliability
A high‑level comparison based on brand reliability history and early EV‑specific issues.
| Model | Brand reliability reputation | EV‑specific issue trend | Overall reliability outlook |
|---|---|---|---|
| Lexus RZ | Very strong (Lexus near top of most rankings) | Software/HVAC recall; some charging quirks, few major mechanical failures so far. | Above‑average for an EV, especially for a first‑gen model. |
| Tesla Model Y | Improving, but more variable | Frequent minor build‑quality and infotainment issues; powertrain generally solid. | Average to above‑average depending on build year; more variance car‑to‑car. |
| Hyundai Ioniq 5 | Mixed but improving | Some 12‑volt battery and charging‑system complaints; software updates have helped. | Average; newer builds seem better than early production. |
| Kia EV6 | Similar to Ioniq 5 | Largely the same platform story as Ioniq 5. | Average; great driver, but not a Lexus‑level reliability play yet. |
| Mercedes EQE SUV | Below Lexus in most rankings | Complex electronics and air‑suspension systems add risk. | So‑so; premium experience but more potential failure points. |
| Genesis GV60 | Young brand with limited long‑term data | High content, complex tech; still building a track record. | Too early to call; not as conservative as Lexus in design or tuning. |
These are broad trends, not guarantees about any individual vehicle. A pre‑purchase inspection is still key, especially for used EVs.
Where the RZ earns its keep
Maintenance, warranty, and long‑term costs
One of the hidden strengths of the 2024 Lexus RZ is that it behaves like a typical Lexus at the service department, just with fewer moving parts to service. No oil changes, no exhaust system, no spark plugs, and a track record of dealers who understand how to keep a luxury vehicle quiet and tight.
- EV‑specific maintenance mostly comes down to tire rotations, brake inspections, cabin filters, and periodic coolant checks for battery and power electronics.
- You’ll eventually replace tires more often than you might expect; instant torque and heavy curb weight are hard on rubber.
- Brake wear is generally low thanks to regeneration, but you’ll still want to prevent caliper corrosion in winter climates.
- Lexus’s reputation for reasonable long‑term repair rates versus German luxury brands should carry over here, especially once parts become more common.
How Recharged can simplify RZ ownership costs
Shopping used? Lexus RZ reliability checklist
Because the RZ is still young, the used market is just starting to fill in, often with off‑lease or low‑mileage examples. That’s an opportunity if you’re careful. Here’s how to put 2024 Lexus RZ reliability under the microscope before you buy.
Pre‑purchase reliability checklist for a used Lexus RZ
1. Confirm recall and software updates
Ask for service records or a printout from a Lexus dealer showing that the HVAC/defroster recall has been completed and that all software updates are current. On a Recharged vehicle, this is the kind of detail we highlight in the Recharged Score Report.
2. Pull a detailed charge‑and‑range history
On a test drive, reset a trip meter, drive a known distance, and compare energy used and projected range. You’re looking for consistency, sudden, unexplained drops in range can be a red flag.
3. Test AC and heater thoroughly
Run the climate system in full heat, full cool, and defrost modes. If the windshield fogs instead of clears, or the system behaves oddly, budget time for a dealer visit before winter.
4. Try multiple charging scenarios
If possible, plug into both a Level 2 charger and a DC fast charger. Make sure sessions start reliably and that the car reaches expected charge speeds for its state of charge and temperature.
5. Listen for wind and trim noise
On the highway, listen for excessive wind hiss around the mirrors or doors and for rattles over rough pavement. These are comfort issues, but on a luxury EV, they matter.
6. Have an EV‑savvy inspection done
A standard pre‑purchase inspection is good; an EV‑specialist inspection is better. Recharged vehicles are evaluated with EV‑specific diagnostics, including battery health, so you’re not guessing.
