The power steering motor fails at random and without warning, creating an imminent wreck hazard. At any time, the wheel will lose all power steering and simultaneously illuminate a red steering wheel warning on your dashboard. It takes significant force to turn the wheel once this happens. Secondly, when turning, a normal cars steering wheel will naturally "unwind" after a turn and smoothly straig
... hten back up while driving. During this motor failure, the steering wheel remains stiffly stationary, pulling you into a potentially unwanted or dangerous direction (ditch, oncoming traffic, etc) unless you fight to straighten it. As a middle aged adult male, I can fight it well enough to keep it under control until I can pull over and turn off/on the car to reset the system. I fear this would become incredibly dangerous if driven by somebody who is older, frail/injured or physically weak. This issue started with only a few thousand miles and has progressively become more and more common, now happening multiple times just this week. A large amount of owners have reported the same issue, with some even being steered into oncoming traffic lanes during a failure. The steering instantly and without warning becomes incredibly heavy. It takes substantial force to turn the wheel. I am experiencing the exact same issue that has become the subject of multiple forums online and other's experiences trying to get it dealt with through Hyundai. Being that my car is now over 5 years old, if I were to try to get it replaced, it is out of warranty, despite having the issue exist since only a few thousand miles (3000-4000). I brought it to two separate dealerships, but they couldn't recreate the issue (hence, it being random) and therefore couldn't get a failure code to show up, and in the end not being able to warranty claim a replacement. Since it is becoming more and more common I have called Hyundai USA to try to escalate the issue.Read more

1. Component/System Failure & Availability: The failed component is the engine's internal Camshaft Variable Valve Timing (CVVT) phaser backing bolt within the 3.3L V6 engine assembly. An internal factory bolt unthreaded, backed out, and physically pierced directly through the upper valve cover. The vehicle and intact failed engine are currently located at an authorized Hyundai dealership service c
... enter in [XXX], and remain fully available for immediate physical inspection by federal investigators upon request. 2. Safety Risk: An internal engine bolt unthreading and puncturing through the valve cover creates an extreme safety hazard. A high-velocity metal bolt piercing the engine casing causes immediate engine seizure, sudden loss of motive power at highway speeds, loss of power steering/braking assistance, and massive pressurized oil discharge directly onto red-hot exhaust manifolds, posing a severe risk of sudden catastrophic vehicle fire and multi-vehicle highway collisions. 3. Dealer/Independent Confirmation: Yes. The failure was formally inspected, reproduced, and confirmed by an authorized Hyundai dealership service department. Dealership technicians logged official diagnostic findings under Prior Authorization Case #XXX. 4. Inspection by Manufacturer/Others: Yes. The defect was inspected and escalated directly to Hyundai Motor America (HMA) Corporate Engineering. Corporate engineering officially verified the defect and issued Techline Case #XXX, confirming that an internal factory CVVT backing bolt unthreaded and pierced the valve cover, recommending a full engine replacement. 5. Warning Lights & Prior Symptoms: There were no prior warning lamps, check engine lights, unusual sounds, or advance warning symptoms prior to the failure. The internal hardware failure occurred suddenly and without warning while operating the vehicle at standard operating parameters.

My 2019 Hyundai Tucson repeatedly shuts off while driving , without any warning. It rolls backwards while in park. The car could easily hit me taking things out of the trunk or hit my neighbors walking past my drive. The car has no power. It can’t get up to speed. It shakes and I have to get someone to add oil to it frequently. The first time this happened was in April of 2023. The engine seized
... up and it was towed to Driver’s Village in Cicero, NY. They replaced the engine block. But not the converter. Now, it is happening again. I have had 2 diagnostic tests done. One by my mechanic and the other by Advanced Auto Parts. Both tests say that the problem is the catalytic converter, but Hyundai refuses to fix the problem and will not honor my extended warranty. I have written and called them numerous times for almost 2 years now, about this and they say they will call me back, but they do not. None of the dealerships will even look at my car. I need someone to look at my vehicle. This vehicle is not safe. Other Tucson owners have the same problems with their cars, that I am complaining about. There is a federal emissions warranty that Hyundai claim they have never heard of, that would fix my car and make it safe to drive. I just want Hyundai to stand behind their warranty and fix my car before it kills someone.Read more

The vehicle suffered a sudden, catastrophic internal mechanical engine failure out of nowhere without any warning lights or previous symptoms. An inspection of the engine cylinder revealed a physical hole blown through the top of the Cylinder 2 piston, causing immediate and complete loss of engine compression. This sudden structural failure caused the vehicle to completely lose all propulsion and
... stall unexpectedly while in operation, creating an immediate, severe safety hazard on the road.This vehicle features Hyundai's 2.4L Theta II Gasoline Direct Injection (GDI) engine, a family with a well-documented history of manufacturing defects, severe oil consumption, and catastrophic internal structural failures. Because this failure occurred instantly and without a progressive warning, it put occupants at risk of a severe rear-end collision or stranding in an unsafe traffic pattern. I am filing this safety report because the catastrophic destruction of the internal engine components presents a persistent and dangerous hazard to public safety.Read more

Driving home near my apartment, I had to join a busy highway from a full stop. I found a small gap and tried to accelerate to quickly merge into traffic, when my car made a high pitched alert noise and noticably did not accelerate beyond about 25 miles per hour on a 45-50mph highway with heavy traffic. I turned on my hazards and still ended up with a line up of cars honking behind me. Flooring the

I was able to exit the highway at slow speed and tried to parallel park in an avaialble spot but could not reverse. I tried to drive on toward my house but the car could not make it up the hill even with the full accelerator pedal down. People were stuck behind me on my street so I turned the car off and back on again and the car appeared to resume normal operation and I was able to drive up the hill. I took the car to the dealer and they were "not able to replicate the error". They did fix a seat belt recall and updated the software for my ECU and said to come back if it happened again...Read more

On August 14, 2026, while driving and decelerating, I heard a knocking sound from the engine and the vehicle had difficulty downshifting. As the transmission shifted from second gear to first, the engine stalled immediately and the vehicle dropped into neutral while on the roadway. I lost propulsion in traffic. The vehicle behind me nearly rear-ended us due to the sudden stall. My children were in
... the vehicle. All dashboard warning lights illuminated at the moment of the stall. I was able to restart the engine and move the vehicle slowly, in first gear only, into a nearby parking lot. The check engine light came on at that restart and has remained on since. The vehicle sat parked and off for approximately 90 minutes. Before restarting, I checked the engine oil level and it was within the normal range. On startup, my children and I both heard a loud knocking sound and noticed an unusual smell, and the engine idled roughly while in Park. I drove approximately 15 minutes home with the rough idle continuing. On arrival the vehicle smelled hot, with a burning odor, although the temperature gauge read approximately mid-scale and was not in the high range. The check engine light remained on and the oil level was again confirmed to be within range. The vehicle has been out of service since the incident and is currently at a dealership awaiting diagnosis. This is a 2020 Hyundai Palisade with approximately 93,000 miles at the time of failure. A sudden loss of motive power in a travel lane is a safety defect.Read more

I am reporting Hyundai’s failure to complete open Campaign 127/NHTSA Recall 15V-100 on my 2009 Hyundai Elantra. I acquired the vehicle from a family member in late July 2026 after the previous owner died and the vehicle was delayed in probate. I sought recall service immediately after legal transfer. Component/system: The Electronic Power Steering (EPS) failed. Power steering assist is completel
... y unavailable. The EPS warning lamp is illuminated and the EPS module reports DTC C1604. The vehicle and EPS system remain at [XXX] Hyundai in [XXX] and are available for inspection upon request. Safety risk: The vehicle was driven from [XXX] to [XXX] during transportation during its transfer to me, and the power steering failed en route. Loss of steering assist substantially increased steering effort suddenly& created a safety risk to the driver, passengers and other motorists. Dealer confirmation: Yes. The condition is recognized by [XXX] Hyundai. I presented the vehicle on XXX specifically for the open EPS recall, and it has remained there since. This is the second area Hyundai dealer that attempted to decline recall service. [XXX] states it cannot perform the prescribed software update because the required Hyundai tablet/programming equipment is no longer available. The dealer has also pressured me to retrieve the unrepaired vehicle and attempted to charge for diagnostics. Other inspections: Hyundai Consumer Affairs is involved under case #XXX. No police or insurance representative has inspected the vehicle. Hyundai’s latest update is that it is attempting to source either the required computer or part, but no remedy or completion date has been provided. Warnings/symptoms: When the EPS failed, the EPS warning lamp illuminated and steering assist was lost. OBD-II/EPS diagnostics subsequently identified C1604. The vehicle has been continuously available for recall repair since XXX. Thank you for your review & assistance with this.

2019 Hyundai Elantra with 2.0L Nu MPI engine suffered catastrophic engine failure at approximately 118,530 miles. Vehicle is currently at the [XXX] Hyundai dealership. Vehicle appears to fall within the exact parameters of Hyundai Recall 203/NHTSA 21V-301. Have spoken to the dealership as well as Hyundai corporate and they have refused to either honor their own recall campaign or do a goodwill ser
... vice to replace the engine, citing my VIN does not fall under their recall campaign, however they have yet to provide any reason, and according to their own campaign 203 recall information my vehicle meets the exact criteria. I am concerned the recall population may exclude vehicles suffering the same engine defect, and their clearly is a clerical error or something on their behalf, and they appear to not be interested in remedying it, which could and has in my case resulted in potential danger. My car died in the middle of [XXX], and had I been in heavy traffic and could not have coasted it down a hill to a parking lot almost certainly would have resulted in a collision. I was fortunate enough to at the time be in light traffic. Upon restarting car motor made a horrendous knocking noise, which is symptomatic of exactly what recall campaign 203 warned of with the defective engines they installed in my series of vehicles. Hyundai denied goodwill solely based on time in service and mileage rather than identifying a different failure mechanism, and as of the time of writing this has not provided an explanation of why according to them my VIN doesn't fall in their campaign, when clearly it should as it is the correct year, correct factory stock engine, correct place if manufacture, and the very same symptoms they published in their campaign. They have told me I need new engine, as was obvious by the fact it's disabled and sounds as if a rod has thrown. I have brought this to their attention every day for going on 2-3 weeks.

This mainly concerns the forward collision detection sensor, if that’s even what it’s actually called. My vehicle is available for testing and inspection. I was driving on an interstate, with my adaptive cruise control set to 75 mph. I was in the left of 3 lanes when got to a curve that went to the right. As I came to the beginning of the curve, all of a sudden my dash is warning me of a fo
... rward collision and the car started braking hard on its own. There is a metal guardrail that separates the 2 sides of the interstate and cars are also coming from the other direction. There wasn’t anyone behind me, thank goodness. If there had been, I can’t say for sure what would have happened, but it would not have been good. It took a hot minute for me to figure out what it was doing so I could stop it and get back up to speed. It scared me when it happened. When I go the same way without my cruise control on, it doesn’t happen. That’s how I know it has something to do with how it’s all connected. This has happened twice at 2 different places since I got the car in May of 2024. I don’t use my cruise control hardly at all now because I’m scared it’s going to suddenly brake again. I wasn’t sure what could be done about it. I put the info on the Hyundai owner surveys but nothing ever happened. I found the NHTSA completely by accident. I want someone to inspect it and try to recreate it, but it’s an awfully dangerous thing to try. Nobody has yet. It’s not like it’s a noise or a rattle. The only thing that I would consider a warning was the crash detection warning on the dash screen that flashes red. That started right about the time that the brakes were activated.Read more

The A/C evaporator core and the core seal needs replacing on 2020 Hyundai Sonata. Car is 6 years old. I already have a confirmed diagnosis with a PPM refrigerant leak tester at the condensate drain line The diagnosis is 100% confirmed. The evaporator is leaking heavily—we pulled 274 PPM at the drain tube and 177 PPM inside the cabin behind the glove box so refrigerent has been leaking out of the

I am submitting a safety complaint regarding a recurring, unresolved electrical defect in my 2020 Hyundai Sonata SEL. The vehicle fails to recognize when the ignition is switched off, leaving core vehicle systems active and causing severe parasitic battery drain that leaves the car immobilized. Description of the Problem: False "On" Status: After parking, turning off the engine, and exitin
... g the vehicle, the car continues to register as though the ignition is still active/on (accessories, cluster, or vehicle network remain awake). Severe Parasitic Draw: Because the vehicle fails to shut down its electrical circuits, the 12-volt battery repeatedly discharges overnight or while parked for short durations. Battery Replacement Did Not Resolve Issue: The 12-volt battery was replaced with a brand-new unit to eliminate typical wear, yet the drain and false "on" behavior persisted immediately. Frequency: The vehicle frequently fails to start, requiring constant jump-starts or roadside assistance to operate. Safety Hazard: This defect creates a direct safety risk by repeatedly stranding the driver without warning in public locations, traffic stops, or remote areas. In addition, an electrical system that fails to enter a sleep state creates a potential hazard for component overheating, failure of electronic security and locking systems, or total electrical failure while attempting to restart or operate auxiliary safety equipment. Other Hyundai owners have reported identical issues where the body control modules or ignition logic fail to power down. Corrective Action Requested: I request that the NHTSA investigate this electrical shutdown defect across the 2020 Hyundai Sonata model year to identify whether a faulty Body Control Module (BCM), smart key receiver, or ignition switch relay requires a safety recall and software or hardware remediation. Battery replaced on 09/04/2026 Car inspected/diagnosed by Hyundai Dealership on 09/03/2026Read more
