Numerous plug-in hybrids are subject to an urgent recall due to a potential fire hazard. The 2021 and 2022 models of Toyota RAV4 Prime along with the 2022 Lexus NX 450h+ fall within this recall. The National Highway Traffic Safety Administration (NHTSA) advises owners to avoid charging these vehicles under cold conditions while the issue remains unresolved.
The recall encompasses a broad range of 43,442 vehicles, produced between the periods of Nov. 25, 2019, through to May 27, 2022. A defective current-rectifying module residing within the DC-DC converters of these vehicles was found to be potentially compromised during production by a supplier. The resultant damage holds the potential for a short circuit, as outlined by the NHTSA.
Failure of the module could trigger a short circuit, facilitating continuous flow of current from the 12-volt battery through the module. Such an event could generate significant heat, leading to damage to other components situated outside the DC-DC converter and even create a fire hazard, a risk underscored by the NHTSA.
Dealers stand ready to replace the compromised DC-DC converter at no cost. Toyota suggests owners circumvent charging their vehicles when ambient air temperatures dip below 41 degrees Fahrenheit. Given the current summer season in the U.S., this precaution should pose minimal inconvenience across most regions.
Toyota is currently unable to quantify the proportion of recalled vehicles that indeed harbor a damaged DC-DC converter. Despite this, Toyota affirms that no affected vehicles have been identified within new dealer inventories. A stop-sale order for certified pre-owned RAV4 Primes has been issued by the automaker.
The RAV4 Prime, debuted in the 2021 model year, garners acclaim for its formidable efficiency, range, and performance metrics. Its sibling, the 2022 Lexus NX 450h+, shares both platform and powertrain.
Both models have previously been subject to recalls. Earlier this year, a software-related stalling issue prompted the recall of the RAV4 Prime. The Lexus NX 450h+ was subject to two recalls in 2022: one due to missing welds impacting hybrid and gasoline NX models, and the other for a stability control software issue affecting several models of Lexus and Toyota.
Despite these setbacks, the RAV4 Prime has sustained strong sales, at times constrained by Toyota’s supply capacity. Following its summer 2020 launch, it rapidly ascended to the status of the fastest-selling new car in March 2021, determined by time spent on dealership lots, a testament to Toyota’s successful attempt to satiate pent-up demand.
