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 recurring defect and repeated failed repair attempts, but the issue continues despite major drivetrain repairs. Hyundai Motors America Consumer Affairs has not been able to help me with this either. They also didn't provide me with the Federal Agency number when I requested them in order to reach out and seek help from the agencies. Hyundai didn't help me in any way. There were no warnings. They have been able to reproduce the issue but do not want to resolve the issue. I strongly believe no vehicle is designed in a way that it jerks and downshifts in a harsh manner causing distress to the driver/owner.

Vehicle developed clunking noise in the steering. Was told it was coupler issue. The dealership, Nlorthbay Hyundai, in Petaluma, California, was negligent in the replacement, creating a grinding metal on metal noise, and damaged the steering column as well. The Dealership refused failed to correct the damage and attempted to defraud me over $3,000 for an entirely new steering column, and refuse to honor promised repair warranty despite their own negligence that created the damage. I found out that Hyundai models including mine have coupler issues involving recalls, years ago. I was not aware of this, and so not sure if my vehicle was part of the recall. However, Hyundai Motor America failed to notify me to take my vehicle in for a safety check for the vehicle coupler. And while I found that that my vehicle qualified for an extended warranty due to the recall, HMA so lacking in responsibility, sound business and moral ethics, let alone serious concern for my safety, claims that my vehicle is past the extended warranty by a completely insignificant mileage. As far as am concerned my vehicle is not safe to drive, and it remains at the dealership while I exhaust all avenues to have my car fixed. I have documents including clear repair notes and service request documents to support my complaint. Complaint being filed against both the dealership, Northbay Hyundai and the manufacturer, Hyundai Motor America.

While driving back into town on the interstate, my oil plug fell out of my car. It was not known at the time the oil plug was what fell out. I remember hearing a clunk underneath my car. About 5-10 minutes after I heard the noise, my oil light flashed, and I could feel my car unable to accelerate further. I pulled over to the side of the road and my engine stalled. I had it towed to a body shop. The next morning, they called and said the oil plug was missing and there was no damage to my undercarriage. My engine was ruined and I was quoted $9,400 for the repair, which is probably more than the value of my car, effectively totaling it. My last oil change was November 12th, 2025 where my odometer was at 82,633. This occurred after 3,393 miles and about 2 months from this most recent oil change. I had not seen oil leaking from my vehicle well before this happened, and I had no indicator lights on or flashing well before this incident. My engine has not previously been checked for HYUNDAI TSB 21-EM-003H, HYUNDAI TSB 21-EM-004H, or KIA TSB 222.

Vehicle started to violently lurch when shifted into drive. A week later loud clunking sound also started when shifting into drive. Sometimes would not go into drive and had to use manual 1st, 2nd, etc. Reverse was fine, no issues. No dash lights ever came on. Auto parts store had error code P0722. Have a diagnostic appt in a week at local Hyundai dealer. We may attempt to replace input/output speed sensor to solve, but probably will let dealership do diag first. Mileage approx 84686. Very dangerous at stop lights if can not get car into drive. Crash risk is high.

The contact owns a 2013 Hyundai Elantra. The contact stated that there was a lot of play in the steering wheel, and the steering wheel moved back and forth with no resistance while the vehicle was being driven or while idling. There was a loud clunking noise coming from the steering column while turning the steering wheel to the left or the right. The vehicle was taken to a certified mechanic, who diagnosed that the steering column flexible coupler had failed and caused the wheels to not respond correctly while turning the steering wheel. The contact was informed that the steering column flexible coupler needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 51,000.

My steering wheel has been shaking and having a clunking sound when I accelerate over 60 miles, go over any bumps, and turn. I had my mechanic diagnose it and I was told the steering coupler was bad. I did some research to see if it was a recall and it wasn't. Then I saw on Hyundai.com then I could check my VIN and verify if my vehicle qualified for the extended warranty for this issue. My vehicle qualified however after contacting customer service directly to verify, they advise me my vehicle did not qualify because of being over 100,000 miles. Prior to contacting them I saw that they had a statement saying that this issue was not safety related. I didn't believe that to be correct because my mechanic told me otherwise, and information I saw regarding Google searches said the opposite. Also, my own experience whenever that shaking of my steering wheel occurs I literally have to use both of my hands to control it. Therefore I believe it is a safety issue that absolutely needs to be revisited as being such. I was advised on that call to take it to the dealership and have them diagnose it and advise headquarters directly however I made it clear that I did not want to have to incur a diagnostic fee when the initial diagnostic I had was free and I have the estimate breakdown from my mechanic. And I did not believe that there should be any diagnostic fee for a safety concern. I did advise them that I was going to contact the federal safety agency and advised them of this circumstance in order for it to be reviewed.

While diving the vehicle started to sputter and the ignition turned off. I was able to start it but the vehicle was making loud clunking sounds and max speed of 10mph. I pulled off on the side of the road and called for a tow to a reputable repair clinic. I told them what happened and they stayed they would be required to remove the engine to determine the issue. $$$ I paid the funds and they informed me the engine was shot. The vehicle has just over 80,000 miles. I contacted Hyundai directly and was told the manufacturer 100,000 mile powertrain warranty was invalid due to me not being the I original owner. I convinced them to take a look and make their determination. After paying out of pocket again for towing and the $175 I initial service fee Hyundai again told me the engine was shot and their was other issues alongside the engine that would need to be fixed. They gave me a quote of over $16,000+ on a vehicle that was less than 6 years old and under 85000 miles. NONE of which they stated was covered under their powertrain warranty. The vehicle is blue booked at about $5,000 and I spent less the what would be required to repair the vehicle. Hyundai has been zero help, they have not supported their product even after I was told by a reputable resalesman that there is a silent recall on this engine for this issue. Im left without a car, still being required to pay the car payment to the loan company and keep full coverage on a car that hasn't driven since early May 2024 and the insurance company isn't helping because the vehicle wasn't in a accident and is an electrical/manufacturing issue, regardless that I have loan lease payoff. I honestly need some advice. Not to mention I am a disabled veteran, Hyundai will not pull any strings. It's sad because I know this is no fault of my own and had taken care of all the vehicles needs when required (oil, tires, spark plugs, alignments ect.. what should I do??

The clutch/transmission clunks or jerks randomly when accelerator is pressed to gain speed, from stop or passing, in any drive mode. Believe this has been going on the past several years.

2013 Elantra coupe se.The car wanders on the highway like a boat constantly left and right all over the lane and if/when you hit a dip or bump it REALLY throws the car around! There's Obviously issues with the suspension on a MULTITUDE of these model/year vehicles if not ALL of theml. It is VERY dangerous and needs to be addressed and recalled. I do not have an alignment issue as the tires brakes rotors and calipers are all new no dragging /pulling etc and the tires are properly pressured as well. Extremely well maintained car by the owner EXTREMELY poorly Engineered by the Maker! The steering coupler has been replaced also taking the play out of the wheel as those things are a small rubber "cog wheel" that wears completely to nothing causing severe play and a clunking noise in the wheel between the turning of left or right as that component acts as a spacer/gear/vibration absorber between the steering shaft and the steering assist helper motor gears these cars ALSO were sold knowing they were piston slap engines yet Still never issued a recall until YEARS and multi millions of complaints later only to only cover certain years and models yet they All had the same engine. Imagine the IDIOCY! I will NEVER purchase a Hyundai or a Kia EVER again rest assured! I do my research and homework on every potential item I'm looking into possibly getting yet Nowhere at the time was there any info regarding they were piston slap engines turning these out by the multi millions and trying to hide the fact until they no longer could. Disgustingly Sad that they do not stand behind there product!
