Vehicle had several non-starts. I took it to the dealer a couple of times and they could not duplicate the problem. This problem continued for a couple years before I took it to an independent mechanic. Said mechanic put it on a lift and found a loose power cable barely connected to the starter. Luckily this never caused a short, spark, or fire. From my searching online it appears this is a non-infrequent issue with Hyundai's.

driver side brake light went out I did have it repaired right away since I knew it was a safety hazard for anyone behind me. And sometimes I do see the same model on the road with the same issue. I don't think the running light is a safety issue but also have a problem with that going out also.

Burning oil at any unacceptable rate. I have made sure to have preventative maintenance and oil changes done every 3K miles. Hyundai needs to address this problem that appears to be plaguing many drivers.

Vehicle was recently purchased and brought in to service recall 22-01-030H (TCU Update and IVT Replacement) Fred Bean Hyundai of Langhorne (1106 E Lincoln Highway, Langhorne, PA, 19047) did the software update, but refuses to honor the IVT replacement as part of the recall, despite the transmission not working and needing to be towed to the dealership. They are attempting to charge me a minimum $5000 to replace the transmission, despite the replacement being covered under this recall campaign. Please contact me and advise if I should pay them and am then entitled to a reimbursement or if I should even have to pay them in the first place. They currently have my vehicle and I can't even drive it off-lot due to failed transmission.

Every time I go up a hill the slippery road light comes up. It’s hard to drive straight. I have to drive under the speed limit going up hills. Sometimes it won’t even let me park. I hear rattling when I drive over a certain speed limit. When I brake I feel the brake pad pushing back. And now my wheels are making noise when I turn them.

Air bags, Dec 20, 2024, crash
On [XXX] at about 1:40 p.m. I was driving to work, and got distracted and had a front-end collision with a tree that was about 1-3 feet next to the side of the road. Extensive damage to the vehicle, and personal injuries occurred (mild concussion, stress fracture of left forearm, bruising/abrasion on ride side torso, sprained left thumb, and abrasions on head). Both the driver and passenger airbags did not deploy which contributed to me almost flying through the windshield. The emergency responders and tow truck operator were very surprised I wasn't in critical condition or dead and noted that the airbags failing was a serious issue and I was lucky. This was reported to the manufacturer and geico insurance on December 20th, and I am currently awaiting to hear back from both to get the inspections scheduled. The vehicle is currently located at OC's Auto at 598 Armistead Blvd, Holt FL 32564. I have already signed papers giving permission for inspections by the insurance company if they request it, but currently inspections haven't been done yet to determine damage estimates or to investigate the airbags.

Engine stalled out, oil light and engine repair light both on, call will not turn over

The high beam shutter that switches from high to low is not working. The car has 68,000 and I don't think this is something that should not work at that low mileage considering it is not in use all the time. I just dont see how it stops working all of a sudden when most of the time drivers do not use their high beams everyday. I just got inspected because its required in our state and both mechanics confirmed this problem. We bought a new bulb and that is when we found out the problem.

Took car into closest mechanic on Saturday 11/09/24 and was informed that both engine mounts were completely shot. Mechanic informed me car was unsafe to drive. Had the car repaired as Hyundai service center was closed. I contacted Hyundai on Monday 11/11/24 to let them know what happened. Received call yesterday from case manager that since I didn't take car to Hyundai facility they would not reimburse me the money paid on the repair. Mechanic at service station said it was unsafe to drive the car of his property. The mechanic also told me he has never seen either engine mount completely shot in care that was only 4 years old.

My vehicle stalled. I was heading to work and vehicle just cut off while driving. The day before it had started making a strange knocking, clicking sound. It will not charge and will not start up. I have not contacted manufacturer and not inspected by manufacturer. I checked vin # but not on recall list. I have kept my car up to date with servicing.The noise it made when it started to stall was really loud and then cut off. My safety was put at risk because I take the highway to work everyday and almost reached the highway that day before it stalled. My car is used for taking my kids to school, doctors appts and work. I am thankful my kids were not in the car when this happened. It had to be pushed off the road in a high traffic area causing a safety issue.

Engine failure: Engine light came on and oil level was abnormally low, even though oil had been changed not long before. Before able to add buy more oil to add when checked, the engine gradually lost pressure and wouldn't stay started. Died in the middle lane of highway all of a sudden. Inspection under hood showed that there was oil all around on engine and some on the ground. Towed to dealership and was not told of interim recall 21V-301. Possible acceleration of engine oil consumption due to bad piston oil rings. Later I researched and found that Hyundai was to inform owners that they were encouraged to check the level of oil periodically between oil changes...that accelerated oil consumption was possible due to this issue of the oil rings. Had to research and find myself.

The warning lamp (engine light) illuminated blinking on and off. Engine code P1327 read on the diagnostic check, riding on the expressway was a little uncomfortable, engine was losing power which is unsafe at high speeds. I’ve contacted the nearest Hyundai dealer and scheduled an appointment for the car repair. I take care of the car and any repairs for maintenance and I never have any problems whatsoever until day. After doing research Hyundai had or has a recall for my vehicle with the VIN NUMBER starting with KMH, for engine replacement and I want to know if Hyundai can fix this issue.

The contact called on behalf of their son who owns a 2020 Hyundai Elantra. The contact stated that while their son was decelerating, speed was unknown, and coming to a stop sign. The next thing their son was able to recall was that the vehicle had suddenly turned right crashing into an electrical pole nearby. The air bags deployed. The driver had lost consciousness during the crash making it difficult to recall all that occurred. The vehicle was towed but they had not yet received any confirmation if the vehicle had been totaled. The electrical pole had fallen and began to catch fire. The fire department had put out the fire. The contact was not completely sure of the damage done to the vehicle. The driver lost consciousness and received an injury on their right arm. Medical attention was needed. The contact could only assume a police report had been filed but had not heard from the police department to confirm. The dealer was not contacted. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The high beams failed and Hyundai will only say that my VIN isn’t part of the recall. Service Campaign T5G covers the exact same symptoms that my car is experiencing. Since Hyundai refuses to acknowledge that the safety issue in this campaign affects more than what they’ve previously admitted, myself and other owners are left to repair the defect at our own expense. A Google search brings up more than a few posts of owners that were also denied the recall because Hyundai says that their 2020 Elantra VIN isn’t included in the recall. This shows that Hyundai refuses to acknowledge the full scope of the vehicles that have defect. Proper headlight function is absolutely necessary. High beams not working even cause state inspections to fail. Hyundai needs to be forced to fix this major defect in a safety critical lighting system, as it is clear that they have no desire to keep the owners of their 2020 Elantras safe.

The soldering of the end cap in the engine fuel rail failed and allowed gas under pressure to leak out. Fuel sprayed out in the engine compartment and the smell was evident inside and outside of the vehicle while in operation. Not sure how it did not start an engine fire. Repairing was a simple task that I handled as this is the only vehicle available to me. Ordered a new fuel rail which was only available from a dealer without issue and completing the repair went without issue. Did not have anyone else look at the problem as once I figured out the problem, did not want to drive the car anywhere. I have the old fuel rail for anyone who needs to inspect it.
