Toyota has issued a non-compliance safety recall on 460,000 vehicles, some of which are Lexus models, due to a software error that can prevent the Vehicle Stability Control (VSC) system from “turning on by default the next time the car is started “under certain conditions”. circumstances.”

The recall affects certain Toyota Venza, Mirai, RAV4 Hybrid, RAV4 Prime, Sienna HV and Highlander HV models as well as Lexus LS500h, LX600, NX350h and NX450h+ vehicles. The recall does not specify model years, but USA Today reports that they are 2020-2022 models.

“Due to improper programming of the Skid Control ECU software, the VSC will not return to the default ON setting on the next ignition cycle,” Toyota spokesman Aaron Fowles told USA Today. “Unless precise operating input conditions are met which will prevent the VSC from returning to the default ON setting on the next ignition cycle, the VSC will automatically return to the default VSC ON setting at any ignition cycle. subsequent ignition.”

For all affected vehicles, Toyota and Lexus dealerships will update the Skid Control ECU software for customers free of charge, according to Toyota’s April 13 recall announcement. The OEM said owners of affected vehicles will be notified by mid-June.

“ESC is a critical safety feature that can prevent a car from sliding out of control in a tight turn,” Consumer Reports said in an article about the recall. “It can also prevent the types of accidents where vehicles are prone to overturning.

“On all cars, if a vehicle’s ESC is disabled, you may see a solid warning light on your dashboard that looks like a car with two curvy lines coming from the tires. (This light may also briefly when the ESC function is actively preventing the car from skidding.) There may be the word “OFF” underneath, or in Toyota and Lexus models it could say “VSC”. The latter stands for “Stability Control vehicle” is what Toyota calls ESC. You should be driving with the ESC on, so if you see one of these lights, check your owner’s manual for instructions on how to turn the ESC back on (this is usually pressing a button with a similar logo.)”

Owners and repairers can use a car’s VIN or license plate information to see if it’s involved in a safety recall at Recalls can also be searched by VIN or year, make, and model at This particular recall is not yet listed by the National Highway Traffic Safety Administration (NHTSA).

Another OEM also recently encountered programming problems, but only in a specific market. Bleeping Computer reported that owners of model year 2014-2017 Mazda vehicles reported that “their HD radio receivers crashed while connecting to a local radio station”.

“The radio and its screen, Bluetooth capabilities, built-in maps and digital clocks were all fried,” the article said.

The Seattle Times reported in February that when Seattle-area motorists tuned into NPR station KUOW, 94.9 on the FM dial, the signal the station sent “fried” a major component, leaving the radios only able to broadcast this station.

Mazda told The Register, “Between 01/24 and 01/31, a Seattle-area radio station sent image files with no extensions (e.g., .jpeg or .gif missing), which caused caused an issue on certain 2014-2017 Mazda vehicles. with older software. Mazda North American Operations (MNAO) distributed service alerts notifying dealers of the issue.

“While dealers are currently experiencing parts delays due to shipping constraints, MNAO will support affected customers with replacement parts. These customers should contact their local Mazda dealership who can submit a goodwill request to Mazda Warranty Service on their behalf, order the parts, and schedule a free repair when the parts arrive.
