What 2023 Hyundai Elantra N owners say
Engine & cooling
The contact owns a 2023 Hyundai Elantra N. The contact stated that there was an oil leak underneath the vehicle. The vehicle was taken to the dealer a total of 4 times. The dealer completed an oil consumption test and found that the engine was consuming one quart of engine oil every 100 miles driven. The vehicle had failed the oil consumption test twice. The dealer diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 1,520.
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. Sometimes this results in an engine replacement, other times just resetting the code. This issue needs corrected. So far, Hyundai has practically ignored me on this. I have sent in multiple screenshots of the same issues that others have been facing. …
Transmission & drivetrain
While driving through heavy rain on the interstate Friday night the CEL came on and the vehicle immediately lost power and went I to a limo mode causing my car to rapidly lose speed while on the interstate. Restarting the vehicle did nothing. I called the closest Hyundai dealer and they said " oh yeah the N models do that a lot in the rain or through carwashes, it triggers false knock sensor codes, you can try to get a parts store to clear the code or you can come in tomorrow and we will clear the code." I then got a parts store to clear the code and the vehicle has been fine since. I did a quick internet search and apparently this is very common and lots of owners have this happened multiple times a year and the dealer has no fix or intention of a fix
This is a known issue within these new Hyundai N cars and Hyundai is completely clueless. It's a "p1326 code" that pops up after a carwash. Whenever the knock sensor gets wet it automatically puts the car into limp mode at highway speeds and it's very hazardous. There has to be some type of cover that Hyundai has to put over the knock sensor or this will continue to happen to us while it's a brand new car.
