For many Toyota owners, the words “unintended acceleration” bring back unpleasant memories.
However, the phenomenon they describe hasn’t been exclusive to the Japanese automaker; the latest company to face this issue is Hyundai, which is recalling some 2,679 Ioniq Electric hatchbacks in the United States.
First brought to the attention of the National Highway Traffic Safety Administration on December 7, 2021, the recall targets certain 2017–2019 Hyundai Ioniq Electric vehicles built on January 21, 2016 through June 24, 2019 by Hyundai Motor Company in Korea for sale in the United States.
In these affected vehicles, “unexpected acceleration following gas pedal release can increase the risk of a crash.” Here’s what the NHTSA recall notice says about the potential cause of unintended acceleration.
“An unstable electrical ground may cause the vehicle to enter a fail-safe mode with reduced acceleration and power. In certain conditions while in fail-safe mode, the vehicle may accelerate after the gas pedal is released.”
More specifically, Hyundai says that electrical noise is generated due to deterioration of the electrical ground which can create a communication error with the vehicle’s Controller Area Network (CAN) bus.
Needless to say, unexpected acceleration following gas pedal release can increase the risk of a crash. As a remedy, Hyundai dealers will update the EPCU (Electric Power Control Unit) software and repair the ground wiring, free of charge.
It’s worth noting that the braking and steering systems are fully functional during the “fail-safe” mode. Owners are warned of this issue if the EV “Ready” lamp flashes as the vehicle enters “fail-safe” mode. Hyundai adds it is not aware of any crashes, fires, or injuries related to the defect condition.
The first time the automaker became aware of this issue was in June 2021 via a Korean media report regarding an incident alleging unintended acceleration on an Ioniq Electric vehicle in the Korean domestic market.
The automaker will start mailing notification letters to affected owners in the United States on February 4, 2022.
The vehicle malfunctions in fail safe mode.
The electric vehicle has a gas pedal.
This story makes my head hurt.
Gas pedal, exactly.
Charming.
I have a 2017 Hyundai Ioniq Hybrid and I have had this happen to me a couple of times.
Hit the brake and I kicked the gas pedal hard to get out of it.
Didn’t think twice about it. I use cruise control a lot. Don’t know if it has anything to do with anything.
Better take it to the dealer ASAP!......................
Is that oxymoronic or just moronic?
I want it to shoot sparks and bolts, knocking cars out of the way as it cruises.
This story make Baby Jesus cry.
The youngsters still rib me about calling the refrigerator the "ice box". My grandfather (born in the 19th Century) never referred to an automobile but by the word "machine" — "Let's go for a ride in the machine!".
Is this the company that is ceasing development on ICE cars?
I once had a motorcycle that did that. It was quite a thrill.
That should be a fairly easy to locate mechanical problem.
The software for these electronic accelerator systems is likely a good bit more challenging.
EV gas pedal?
Do you park it in a garage?
One of the liabilities of drive by wire. If the servo opens the throttle you accelerate, no matter what the pedal is doing.
no - outside.
Drive by wire cars acting up again. In the old days the gas pedal had a mechanical cable between the gas pedal and the throttle body. NO computer screw-ups allowed.
thanks. I have had it 3 years now...only happened a couple of times...but next time I take it in i will mention it.
Simple solution: delete the “fail-safe mode.”
