“This problem occurred in my previous vehicle which was a 2022 Hyundai Kona N. I took it through a car wash and had a check engine light turn on. The car went into limp mode and I had it towed to the dealership. The check engine light was a code from the knock sensor. Hyundai replaced the engine when the vehicle only had 5,200 miles on it. I have since traded that vehicle for a 2023 Hyundai Elantra N. Upon doing some research, it is a very common issue with the N trims of Kona's and Elantra's to throw a check engine light due to heavy rain or car washes. …”
NHTSA complaint #11514621, filed 2023-03“Hello. While driving my 2023 Elantra N, innthe middle of driving, it set a flashing check engine light. During this event, my car started sputtering in between shifts and would not climb over 2500 rounds per minute. During this event I was driving 70 miles per hour on the highway, causing me to almost get rear ended. The check engine light is flashing but is consitently set. The code that's causing the check engine light is P132600. After doing my own personal research in Elantra N forums, this has been a common fault among many Elantra N models. Hyundai has made no official recall for it yet.”
NHTSA complaint #11516164, filed 2023-04“When vehicle gets wet, knock sensor trips and puts the vehicle in limp mode. Making it very dangerous to drive since everything is underpowered and makes it hard to get up to speed, shift, etc.”
NHTSA complaint #11605020, filed 2024-07“Code P1326 coming on after car wash. This a known issue across the cars community. Remedy needs to be taken, goes into limp mode on interstate speeds which is very dangerous.”
