Hyundai Ioniq electric recalled due to risk of sudden acceleration

A programming error would be the cause of the recall concerning a risk of sudden acceleration on the Hyundai Ioniq electric from model years 2017 to 2019.

Hyundai Canada is recalling 3,236 units of the electric Ioniq built between January 21, 2016 and June 24, 2019. We therefore cover the 2017 to 2019 model years. According to the manufacturer and Transport Canada, the vehicle could have a problem with programming of the control unit (ECU). This in turn could cause sudden acceleration following a sequence of specific actions on the part of the driver.

The “fail-safe”

Although the situation is important, it can only occur in rare situations where the fail-safe mode is in action. At this time, the EV Ready light will flash, and acceleration may occur even when releasing the accelerator. A precise sequence must be followed for this to happen: the accelerator is quickly engaged at the moment of the appearance of “fail-safe”, a 100% acceleration pressure is applied and thirdly, the accelerator is quickly released. Considering this to be an unusual driving sequence, it is unlikely that anyone will experience the problem.

June 2021

Hyundai had to do intense research to find out in which sequence it was possible to reproduce the situation where the sudden acceleration occurs. The manufacturer was first notified of the problem in June 2021. Fortunately for the few who have experienced the problem, the steering and brake system remain fully functional. At this time, no accidents or injuries have been reported in connection with this recall. Hyundai will be contacting 2017-2019 electric Ioniq owners shortly to make an appointment for the reprogramming of the control unit and the addition of additional safety wiring. This will obviously be free of charge for customers.
