If you’re looking at a 2024 Toyota bZ4X, you’re probably expecting classic Toyota dependability in an electric SUV wrapper. The reality is more complicated. The 2024 Toyota bZ4X reliability story includes some bright spots, but also software glitches, 12‑volt battery complaints, and a high‑profile HVAC recall you need to understand, especially if you’re shopping used.

Key takeaway
How reliable is the 2024 Toyota bZ4X?
From a high‑level view, the 2024 Toyota bZ4X is **less reliable than the average new vehicle**, according to major third‑party testing organizations that track owner surveys and problem rates. That’s unusual for Toyota, a brand that often sits near the top of reliability rankings. The bZ4X’s trouble spots are mostly in software, auxiliary electrical systems, HVAC, and charging behavior rather than catastrophic drivetrain failures.
Battery‑electric powertrains are mechanically simple, no engine oil, no multi‑speed transmission, so you’re not seeing blown head gaskets or failed automatic gearboxes here. Instead, what hurts the 2024 bZ4X reliability score are nuisance issues: warning lights, frozen camera displays, climate‑control quirks, and a pattern of 12‑volt battery failures that can leave the vehicle unable to ‘wake up’ even when the main traction battery has plenty of charge.

Service record tip
Battery, 12V system and charging reliability
The heart of any EV reliability discussion is the battery and charging system. With the 2024 bZ4X you need to think about **two different batteries**: the big high‑voltage pack that actually moves the vehicle, and the small 12‑volt auxiliary battery that runs computers, locks and control modules.
High‑voltage traction battery
- The main pack in the 2024 bZ4X has not attracted widespread reports of early capacity loss or outright failure. That’s good news for long‑term value.
- Range is on the low side versus rivals (around the low‑ to mid‑200‑mile EPA range depending on configuration), but that’s a design tradeoff rather than a reliability flaw.
- Toyota covers the battery with a long hybrid/EV component warranty, which is a key safety net for used‑EV buyers.
12‑volt auxiliary battery
- The 12V system is a genuine weak spot. Owner complaints describe cars going totally dead, no power, no start, sometimes repeatedly, even with a replacement 12V battery.
- Some reports tie this to the connected‑car app polling the vehicle frequently, or to the car sitting for several days without being driven.
- As of late 2025 there has been **no dedicated recall** for this issue; dealers typically replace the battery under warranty and may advise work‑arounds like minimizing extended accessory‑mode use.
Why a weak 12V battery matters
Charging reliability is mixed. Some 2024 bZ4X owners report completely trouble‑free Level 2 and DC fast‑charging experiences, while others talk about certain home wallboxes or public stations refusing to handshake or ending charging sessions early. In survey data, **EV charging** is called out as one of the most common trouble spots for this model.
Recalls affecting 2024 Toyota bZ4X models
By early 2026, the 2023–2025 Toyota bZ4X has been included in **multiple recalls**. Not every campaign applies to every individual VIN, so you’ll want to run a recall check by VIN through Toyota or NHTSA, but here are the big ones you’re likely to see on a 2024 model:
Major recalls that can affect a 2024 bZ4X
Summary of key U.S. recalls involving the 2023–2025 Toyota bZ4X that a used‑EV shopper should ask about.
| Issue | Model years | What can happen | Dealer remedy |
|---|---|---|---|
| HVAC / defroster software fault | 2023–2025 | HVAC system can enter a failsafe mode after certain compressor faults, leaving the defroster and defogger inoperative and reducing visibility in cold or humid conditions. | Update HVAC control ECU software and inspect/replace the electric compressor if needed, free of charge. |
| Rearview camera image freezing or blank | 2022–2026 (various Toyota/Lexus/Subaru EVs incl. bZ4X) | Panoramic View Monitor software can cause the rear camera image to freeze or disappear, increasing the risk of backing up without a clear rear view. | Update parking assist / camera software at the dealer. |
| Incorrect load‑carrying capacity label (Gulf States Toyota region) | Some 2023–2024 bZ4X sold through Gulf States Toyota | Accessory weight label may list the wrong maximum capacity, potentially encouraging overloading. | Mail out corrected labels to affected owners; dealer can apply updated label if necessary. |
Always verify recall status by VIN; not every vehicle is affected by every campaign.
How to check recall status before you buy
How the 2024 bZ4X’s reliability compares to rival EVs
The fairest way to look at 2024 Toyota bZ4X reliability is to compare it with other compact electric crossovers launched in the same era, vehicles like the Hyundai Ioniq 5, Kia EV6, Volkswagen ID.4, and the related Subaru Solterra and Lexus RZ.
Toyota bZ4X / Subaru Solterra
- Shared platform and many shared issues, including HVAC software recall and some 12V battery complaints.
- Range and charging speed trail the best in class, but mechanical durability of the main battery and motors appears acceptable so far.
- Predicted‑reliability scores sit **below average** for the segment.
Hyundai Ioniq 5 / Kia EV6
- Faster DC charging and generally stronger owner satisfaction scores.
- Have had their own recalls and software updates, but aren’t flagged as broadly below‑average in reliability the way the bZ4X is.
- Some owners report occasional software and charging quirks, but 12V‑battery complaints are less concentrated.
Volkswagen ID.4, others
- ID.4 has seen software problems and infotainment headaches of its own, especially in early builds.
- Compared with these, the bZ4X sits in the **middle of the EV pack**, not the worst, not the best, but disappointing versus Toyota’s usual reputation.

Reliability checklist if you’re buying a used 2024 bZ4X
Used 2024 bZ4X reliability checklist
1. Scan for HVAC and camera recalls
Use the VIN to confirm the HVAC/defroster and rear‑camera recalls have been completed. Ask for service receipts that show the software update dates and any compressor replacements.
2. Ask about 12V battery history
Has the 12V battery been replaced? How many times? A single replacement on a two‑year‑old EV isn’t a deal‑breaker, but repeated failures without a diagnosis should make you pause.
3. Test cold starts and sit time
If possible, see how the vehicle behaves after sitting overnight or for several days. You’re watching for slow wakes, warning lights, or no‑start situations that might hint at 12V draw problems.
4. Verify home and public charging
Bring your Level 2 setup or use a common home charger to verify reliable charging at 240V. Then, test a DC fast charger to make sure the car handshakes correctly and charges at expected speeds.
5. Review software and OTA updates
Ask which software versions are installed and when the last dealer update was done. A bZ4X that’s been regularly updated is usually a safer bet than one that hasn’t seen the service bay in years.
6. Get a battery‑health report
For a used EV, a **professional battery‑health test** is as important as a pre‑purchase inspection on a gas car. Recharged includes a Recharged Score Report with verified battery health and fair‑market pricing for every EV we offer.

Owner feedback on the 2024 bZ4X is **polarized**. Some drivers give it five stars for comfort, quietness and low operating costs, reporting only a modest bump in their electric bill and big savings versus gasoline. Others rate it very poorly for value and reliability, citing repeated service visits and unresolved electrical issues.
- On consumer‑review sites, the 2024 bZ4X earns mixed scores, with a significant share of one‑star reviews alongside a smaller group of very satisfied owners.
- Positive reviews tend to highlight a smooth ride, quiet cabin, generous standard safety tech and the ease of daily commuting within the bZ4X’s range window.
- Negative reviews focus on dead 12V batteries, inconsistent charging behavior, and frustrations with dealer responses that swap parts without addressing root causes.
“My 2024 bZ4X died twice in the first two months. The dealer replaced the battery, then the new one failed again. Toyota couldn’t explain why.”
Watch how the previous owner used it
Is the 2024 Toyota bZ4X a good used EV to buy?
When a used 2024 bZ4X can make sense
- You find a **well‑documented example** with completed recalls, recent software updates, and no history of repeated 12V failures.
- Your daily driving is comfortably inside its range envelope, so you’re not relying on DC fast chargers multiple times a week.
- You value Toyota’s safety tech and a calm, easy‑to‑drive feel more than maximum range or blazing fast charging speeds.
- The price reflects its below‑average reliability ranking relative to segment leaders.
When you might want to look elsewhere
- You can’t tolerate nuisance issues, warning lights, the occasional no‑start, or extra trips to the dealer, even if they’re covered under warranty.
- You live in a very cold or very hot climate where HVAC performance and defrosting are critical and you don’t want to think about software recalls.
- You plan to road‑trip frequently and want faster DC charging and longer range from something like a Hyundai Ioniq 5, Kia EV6 or Tesla Model Y.
- The particular bZ4X you’re considering shows sparse records or a repeated pattern of battery or electrical complaints.
The 2024 Toyota bZ4X isn’t the disaster some online horror stories make it out to be, but it’s also not the slam‑dunk, set‑and‑forget Toyota experience you might be expecting. If you go in with clear eyes, armed with a recall check, a battery‑health report, and a careful look at 12‑volt and charging behavior, it can be a comfortable, efficient EV at the right price. If you’d rather skip the guesswork, shopping through a used‑EV specialist like Recharged can give you the transparency and support that early‑generation EVs like the bZ4X really deserve.
