2023 Hyundai Elantra electrical system 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.”

“Vehicle is still in my possession and available for inspection upon request. My safety and the safety of others was put at risk due to vibration when braking caused by warped rotors, a vehicle that pulls to one side with an off-center steering wheel, abnormal tire wear including a bald tire with a sidewall bubble, and a transmission that has twice failed and recently felt like it was going to stall while accelerating. The wheel bearing/suspension noise was confirmed by an independent repair shop (Firestone) using a listening device at highway speed; however, the dealership's own inspection gave a conflicting finding of no issue. The transmission issues have been reproduced by the dealership in the sense that two replacements were performed; however, the most recent stalling sensation has not yet been independently confirmed. The vehicle has not been inspected by police or insurance. Warning lamps/symptoms included a horn malfunction (tied to Hyundai TSB 25-BE-005H-2) and headlight issues that coincided with transmission slipping on more than one occasion. These symptoms first appeared at approximately 10,000 miles with a wheel alignment flag, and have recurred…”

“2023 Hyundai Elantra SEL. Car has been slow to start this week. When I depress the brake pedal and push to start, it will start then shut off in the middle of starting then I have to try again or it will sputter then fully start but every safety alert and electrical alarm will go off in my car and nothing clears it until I drive for about 5 minutes then they all clear. I went to AutoZone and they said my battery was normal health. When this slow start happens I also notice that my vehicle doesn’t accelerate as well and it feels like it’s trying too hard to the point it will jerk forward even when I’m only lightly pressing the accelerator. I noticed this, 2 winters ago (2024) as well and I thought it was due to the very cold weather we had. Brought it to my sister’s fiancée and he couldn’t find any DTC’s but agreed something felt off. The problem stopped and now it’s the middle of summer 2 years later and doing the same thing, to the point where I’m trying to merge onto I-95 and my car isn’t accelerating fast enough and I almost got rear ended!! It only happens at speeds under 50 and is extremely unsafe to have a vehicle where you don’t know if it will just turn…”

“The horn is intermittenly failing and was verified by a Weimer Hyundai in Morgantown, WV on XXX. This is a known defect in 2023 Hyundai Elantras and they have issued an extended warranty to address the problem. An absence of a horn is a safety issue as you cannot signal other drivers in emergency situations. It is unlawful to have a horn that does not operate in most states including WV ([XXX]) which is where I currently reside. While a horn is not required by NHTSA , if it is present it must be operable by driver (Safety Standard No. 101, 49 CFR '571.101). For these reasons I am requesting that this should have and should be considered a SAFETY RECALL which is NOT predicated on mileage. By issuing an extended warranty that stops at 120,000 miles Hyundai does not serve those with higher mileage vehicles. It is not fair for a driver to have to pay out of pocket for a KNOWN DEFECT that should have absolutely been addressed as a SAFETY RECALL. Hyundai has been contacted and I was given a case #42976455 and a case manager named Edward. Weimer was incontact with either him or Hyundai directly and they offered to split the cost of $600.00 intead of taking full…”

“Electrical component with car has been malfunctioning. ADAS system malfunctioning (all the lights on the dash have been coming on in and out at different times) despite turning the car on and off. Video and picture evidence has been collected on different days and times this issue has been happening. Blinkers do not work when this is happening. Concerned for safety while driving. Hyundai Dealership is not helping and blowing me off.”

“Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.”
