2023 Hyundai Elantra N Owner Complaints

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. When this check engine light comes on, the vehicle goes into limp mode which is very dangerous if traveling at highway speeds.

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.

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.

Hit a shallow pothole at or around 40-55 miles/hour. Estimate. Strut mount broke. Hit a shallow pot hole and strut mount broke and pulled car to the right. Safety issue for 18 year old driver. Dealer refused to receive vehicle and investigate. Said it was an insurance issue. Insurance inspected car. Adjuster said he has never seen a new car break strut mount. Car bottom graphics and underneath not damaged. Rust was on the brand new strut mount welds. Body shop advises that was reason of failure, rust on welds. Not right for a pothole to break strut and end up totaling out a brand new $38,000 car. Not right that insurance is responsible to pay for it and Hyundai would not even look at vehicle.

I find myself in this situation due to a defect in my 2023 Hyundai, which is under Full Factory Warranty. I have had all my required services completed by Hyundai on time, and as the consumer had no idea anything was wrong with my vehicle. On 31 August 2024, just 25 days after being service by Hyundai Yuma on 6 August 2024, this defect caused a catastrophic failure in my front driver side tire resulting in damage to my vehicle. My vehicle was towed to Hyundai Yuma on 1 September 2024, by Hyundai Roadside Assistance. After an inspection by Hyundai Yuma on 5 September 2024, it was determined that there was a defect in the camber of the alignment of the car that caused the catastrophic tire failure, damage to my vehicle's front skirt and bumper, as well as premature wear on all three existing tires to the point in which they are not safe to remain on the car. The only solution to this defect according to Hyundai Yuma is an Aftermarket component to correct the defect in the camber of the vehicle. Without this Aftermarket addition to the vehicle, the camber would remain out of specifications causing premature wear of any tires placed on the vehicle thus making it unsafe to operate. Therefore my car is currently inoperable and beyond my control

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.

Hyundai dealership “fixed” the recall on my car a few weeks ago. This morning my car stalled out on the highway twice due to fuel pump issues, one of those resulting in my car hitting a guardrail. Every warning light went on in the car and a service message to make an appointment at the dealership popped up. I do not believe this vehicle is safe to keep using

I had turned onto my road when I had to stop just before pulling into my driveway to park when my neighbor began backing up. I saw he was getting close to my vehicle so I began to hit the horn only to find out that it’s inoperable. Unfortunately, since my horn wasn’t working, my car ended up getting hit. Earlier this past week, I had just received a letter in the mail from Hyundai explaining they were extending the warranty on the horns for my model. If my horn was operable at this time, this accident could have been avoided. • the horn failed to operate when I went to hit it to get the other drivers attention only to find out it’s inoperable. • my safety could have definitely been more at risk if it were a higher impact situation. Thankfully it wasn’t. • the problem was acknowledged by Hyundai of America to the point that they sent out extended warranty notices to vehicle owners of my year and model vehicle. But I feel as though this should be a safety recall rather than a than an extended warranty notice. • the last time the horn was inspected by my local Hyundai dealer was in October 2024 during the routine NYS inspection. • there were no warning lights or notification in the computer system in my vehicle stating that my horn had stopped working. I had found out my horn wasn’t working in that very instance when my vehicle got hit by the other vehicle.

The subframe is pressed against the hard brake line. Hyundai is denying warranty claim saying this couldn’t have happened from factory, yet the subframe hasn’t ever been removed and there no evidence of it.
