2023 Hyundai Elantra problems

“I have a 2023 Hyundal Elantra SEL and my rear camera starts flickering and also goes blank frequently. In fact nowadays it is rarely working. I understand that there was a recall for 2021 and 2022 but not for 2023 yet. However it seems the issue continues with 2023 as well cause when I google I see I am not the only one having this issue. I called the dealership and because I am out of warranty they say they will charge as there is no recall for 2023.”

“A month ago my car started making a knocking noise very loudly at start up, and once driving for about 5 to 8 minutes it kind of stops, my speed doesn't accelerate as normal and if I go over 67 mph feels like I'll lose control. I see Hyundai have a knock sensor recall and from the video on the website my car makes same sound but my 2023 Elantra isn't list on the recall list. I'm the first Original owner of the vehicle only at 80,000 miles”

“While driving on [XXX] north near exit [XXX] in rain, at 70 mph Adaptive Cruise Control and Lane Keeping Assistance were on. The vehicle displayed a warning that the smart systems were disabled. The vehicle then began jerking and changing lanes and speed unexpectedly. The steering wheel pulled/jerked forcefully to the left and right and I had difficulty maintaining control of the vehicle. When I attempted to brake, the brake pedal became very hard and could not press down the vehicle did not slow normally. I was able to get the vehicle onto the shoulder and shut it off. After restarting the vehicle, the problem occurred again. The vehicle was towed to Wallace Hyundai dealership in Stewart Florida and is currently being diagnosed. The cause has not yet been determined. Scared me to death.”

“The contact owns a 2023 Hyundai Elantra. The contact stated that while driving at an undisclosed speed, several unknown warning lights flashed on and off on the instrument panel, and the brakes independently activated due to slippery weather conditions. The vehicle was taken to a dealer to be diagnosed; however, the cause of the failure was not determined. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 16,900.”

“The tracking number assigned by NHTSA for this issue is 11733456 I am writing to update and escalate my previously filed safety complaint regarding my vehicle. I recently received my car back from the dealership after they informed me that all issues had been repaired and that the vehicle was safe to drive. However, after getting the vehicle back, it is not the same, and it is not safe to operate. The vehicle pulls strongly to the left while driving, which creates a serious risk of losing control, especially at normal road speeds. In addition, multiple safety and driver‑assistance functions are not working as intended. Despite these issues, the dealership insists that everything is “within specifications” and refused to take further corrective action. Because of these unresolved defects, I am afraid to drive this vehicle. I have already experienced a traumatic incident related to this car, and returning it in this condition has caused significant fear and emotional distress. I cannot go through another dangerous situation. I believe this vehicle poses a genuine safety risk to me and to others on the road. I am requesting that NHTSA review my complaint again,…”

“I purchased a 2023 Hyundai Elantra Hybrid 2023 on December 15, 2023, and since early ownership I have experienced persistent jerking/clunking while slowing to a stop, harsh downshifts, hesitation during braking, and rough transitions between electric and engine power. The issue was first documented around 5,744 miles and continued through approximately six to eight repair/work orders, where dealerships repeatedly described the condition as normal hybrid/DCT behavior while performing software resets, adaptive relearns, and diagnostic checks. After continued complaints, Hyundai Techline became involved and the dealership concluded the vehicle “jerks pretty bad,” leading to a full transmission replacement under warranty. Despite the transmission replacement, the issue persisted and the dealership later confirmed slight clunking during downshifts and discovered a torn engine mount, which was also replaced. The dealership additionally noted that the issue did not occur while driving another Elantra Hybrid or the loaner vehicle, suggesting the condition was specific to my vehicle. I also opened a case with Hyundai Motor America Consumer Affairs regarding the…”
