Toyota bZ4X XEAM10
Weaknesses, engine ratings and buying advice
The bZ4X is Toyota's first mass-production BEV — on the e-TNGA platform, co-developed with Subaru (Solterra). A conservative statement: Toyota builds an EV because it must, not because it's eager.
The bZ4X-FWD has 150 kW and 252 miles EPA range, the bZ4X-AWD with dual motors 160 kW and shorter range. DC charging nominally at 150 kW, in practice often throttled to 50 kW — a criticism. The 12V auxiliary battery drains spontaneously during short standstills.
The most prominent recall concerned wheel bolts: wheels could detach under heavy braking. Toyota issued a stop-sale and fixed the problem.
Test-drive checklist: Test DC charge curve — does it really hit 150 kW? Check 12V battery voltage. Compare highway range (80 mph) vs. EPA. Test regen levels.
2026 market: Between $27,500 and $44,000 — massive depreciation. Expensive as new, a bargain as used.
Insider pick: bZ4X FWD as a two-year-old — maximum range, half the new price.
Engine Overview
The Toyota bZ4X XEAM10 is available with 2 engine variants — from 204 to 218 hp.
Pure electric drive with two motors, one per axle, and around 160 kW of system output. The all-wheel drive is purely electronic, splitting torque on demand — no mechanical transfer case, so it needs little maintenance. Range sits slightly below the single-motor version because of the extra weight; check real-world consumption and the fast-charging curve before buying, as charging speed drops noticeably in the cold and at a high state of charge. Regeneration is easy to modulate. Battery health is the key point: have the state of health read out; the early teething issues of the series are considered resolved.
- !! Recall: Wheel bolts can come loose
The AWD variant is also affected by the wheel bolt recall. Toyota issued a worldwide fix in 2022. When buying used, verify whether the recall has been carried out.
Symptoms: Knocking noise from wheel area; steering wheel vibrations; in the worst case wheel detachment - !! 12V auxiliary battery drains spontaneously from 15,000 km
The 12V auxiliary battery of the bZ4X (AWD) drains even in new vehicles without any apparent cause. Class action lawsuit filed in 2025 against Toyota over a defective 12V battery charging management system.
Symptoms: Vehicle won't power on, display stays dark, doors cannot be opened - !! Recall: Instrument cluster ECU total failure on startup
Recall for bZ4X AWD (prod. 11/2021–08/2023): The instrument cluster ECU can fail completely on startup. Turn signals, hazard lights, and the pre-collision system become inoperative.
Symptoms: Black display on startup, no warning or indicator lights, turn signals and safety systems non-functional
+ 3 more engine weaknesses + vehicle weaknesses
Pure electric vehicle on the e-TNGA platform, front-wheel drive with 150 kW and a solid range of around 400 km. The charging curve tapers off noticeably beyond 70 percent and the system dislikes a cold battery, so precondition in winter for stable charging power. The traction battery is regarded as long-lived thanks to its conservative tuning, with degradation kept modest. Keep an eye on the 12-volt battery, a frequent cause of no-starts. Early examples had a recall for loose wheel bolts, now resolved; software updates improve charging and regeneration.
- !! Recall: Wheel bolts can come loose
Toyota issued a worldwide recall for the bZ4X in 2022: wheel bolts could come loose through hard steering at low speed. Fixed with improved wheel bolts.
Symptoms: Knocking noise from wheel area; steering wheel vibrations; in the worst case wheel detachment - !! 12V auxiliary battery drains spontaneously from 15,000 km
The 12V auxiliary battery of the bZ4X drains even in new vehicles without apparent cause. Owners report up to 4 battery replacements in 8 months. Root cause: defective charge management system.
Symptoms: Vehicle won't power on, display stays dark, doors cannot be opened, all functions dead despite full HV battery - !! Recall: Instrument cluster ECU total failure on startup
Recall for bZ4X (prod. 11/2021–08/2023): The instrument cluster ECU does not fully shut down when the vehicle is switched off. On the next startup the display remains blank. Turn signals and safety systems fail.
Symptoms: Black display on startup, no warning or indicator lights, turn signals and safety systems non-functional

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Recall: Wheel bolts can come loose During sharp cornering and sudden braking the wheel bolts can come loose. 283 vehicles were affected in Germany. Symptoms: Steering wheel vibrates, vehicle pulls to one side, metallic noise from wheel area. | Low | |
| Recall: Curtain airbags incorrectly installed In 2022 bZ4X vehicles, the curtain airbags may have been installed incorrectly. Symptoms: No visible symptom; recall information via Toyota or KBA. | Low | |
| NHTSA 25V577 — Defroster/Defogger Inoperative on HVAC Fault During certain HVAC system faults (e.g., electric compressor failure), the defroster and defogger may become inoperative, reducing driver visibility. NHTSA campaign 25V577, Toyota recall 25TA07. Free software update and compressor inspection at dealer. Symptoms: Windshield fogs up or ices without defrost function activating; HVAC warning indicator. | Low | |
| Recall: Rear camera fails to display A software bug can cause the backup camera image to freeze or fail when shifting into Reverse. Affects bZ4X, Lexus RZ, and Subaru Solterra. Symptoms: Black or frozen image in Reverse |
