Toyota bZ4X reliability & safety rating

There’s no hard data available yet, but the bZ4X should perform well in these areas

Overall rating

4.5 out of 5

Reliability & safety rating rating

4.0 out of 5

Safety and reliability are both traditional Toyota strong points, and there are no indications that will change as the brand transitions to electric power. There isn’t an independent crash-test rating available for the bZ4X available yet, but a strong suite of standard active safety kit should see it do well here.

Toyota bZ4X reliability & problems

Toyota is taking its first proper step into the world of electric vehicles with the bZ4X, but that doesn’t mean there shouldn’t be any big concerns over reliability. The Japanese giant has learned plenty about batteries and electric motors from its decades spent building millions of hybrids, and its dedication to quality and dependability is long-standing. It anticipates the bZ4X’s batteries will retain 90% of their original capacity even after 10 years or 150,000 miles on the road.


In recent years, Toyota has adopted a philosophy of offering a complete suite of active safety equipment across every trim level of its cars, instead of reserving the higher-tech systems for range-topping models. That admirable approach continues with the bZ4X, which gets the latest third-generation iteration of brand’s 'Toyota Safety Sense' suite of driver-assistance and collision-avoidance technology.

Standard crash-avoidance systems include automatic emergency braking with collision warnings, cross-traffic alerts, detection of vehicles approaching an intersection, adaptive cruise control, lane-keeping assistance, road-sign recognition and automatic high-beam headlights.

The only features absent on the entry-level Pure trim level are blind-spot monitoring and a sensor that warns you not to open the doors if a car or bicycle is approaching; these are standard on the Motion, Vision and Premiere Edition. All this should ensure a high score in Euro NCAP crash-testing for the bZ4X, however it hasn’t been through the body’s evaluations just yet.
