Incident date: Mar 16, 2026
My 2020 Hyundai Kona experienced an engine-related malfunction. An authorized Hyundai dealer inspected the vehicle, confirmed diagnostic code P1327, and determined that the complete engine required replacement. Hyundai authorized the replacement, and the vehicle remained out of service for approximately two weeks. The engine defect created a safety concern because an engine malfunction could caus
... e reduced or complete loss of motive power while driving, increasing the risk of a crash. The dealer inspected and removed the original engine; I do not know whether it remains available for further inspection, but the repair order and diagnostic records are available. I am filing this complaint so NHTSA can document this engine failure and determine whether it is related to NHTSA Campaign 21V301 / Hyundai Recall 203 and whether additional investigation or corrective action is warranted.Read more

Since I had Service Campaign 9C2 completed, the car hesitates to start, does a mini-lurch upon cold start and runs rough. Two weeks ago, it was put in park, lurched backwards, then died. The starter and battery have been replaced but this has not helped. The car ran fine before this update was done.

The vehicle will not turn off. I returned it to the Dealer, Oakland Hyundai, and their service department has had the vehicle since 7/27/26. When I brought the vehicle in to service it had 2,519 miles. Service rep has advised that technicians are trying to find the faulty part and have been unsuccessful to date. A technician from another location is scheduled to see the vehicle during the week
... of 8/31/26. I have filed a case with Hyundai America and will send a demand for restitution on 8/28/26. I view this situation as a clear safety issue - the car will not turn off.Read more

While driving, the infotainment screen (to the right of the driver) begins to flicker. Often if turns completely black and reboots. On at least one occasion, it did not come back on at all for the remainder of the trip. The flickering movement is extremely distracting. The loss of navigation is obviously a problem if you don't know where you are and were relying on it. It is dangerous, could r

Component & Inspection: Vehicle engine suffered connecting rod bearing failure and entered restricted P1326 "Limp Home Mode" (max 2,000 RPM). The vehicle is grounded and available for inspection at Bud Clary Hyundai in [XXX].Safety Risk: Sudden, unexpected loss of power occurred while driving, placing me and other drivers at immediate risk on public roads due to the vehicle's inability to maintain
... normal traffic speed or safely accelerate.Dealer & Corporate Confirmation: Active P1326 engine code is confirmed. Car has been held for 14 days. The franchise is violating federal settlement rules by explicitly refusing to execute the mandatory, free mechanical Bearing Clearance Test (BCT) unless I pay out-of-pocket fees.Inspection & Corporate Compliance Failure: Car was brought to the dealer on XXX. The service manager admitted in writing that they are withholding safety diagnostics to protect shop labor hours due to an automated computer flag regarding a clerical title brand discrepancy. Hyundai Corporate is actively enabling this violation; my case manager refuses to issue a manual compliance override for the safety test and is violating federal settlement terms by withholding my contractually mandated alternative transportation.Warning Lamps & Symptoms: Flashing Check Engine Light and limp home mode triggered instantly and unexpectedly on XXX.

My 2020 Hyundai Palisade (3.8L GDI Lambda II V6) consumes engine oil at a rate that empties the crankcase between scheduled oil changes, with no warning lamp illuminating before the oil is gone. This creates a risk of engine seizure and sudden loss of motive power in traffic. The vehicle has repeatedly run rough and felt as though it would stall when slowing or stopping. On 3/10/2025 at 57,026 mi
... les I brought it to a Hyundai dealer because it felt like it was about to stall at traffic lights. The technician found no measurable oil on the dipstick, 4.5 quarts low, and found the camshafts out of time as a result. On 11/25/2025 at 69,851 miles the oil light flickered and the engine ran rough and stuttered. The dealer checked the dipstick and again found no oil on it at all. This was only 5,614 miles after a documented oil and filter change performed by that same dealer. No warning illuminated until the crankcase was already effectively empty, which I consider inadequate warning of imminent engine failure. Consumption has continued and worsened: 1 quart low at 77,202 miles (4/22/2026), 1.5 quarts low at 81,350 (5/14/2026), and 1.2 quarts low at 82,927 (8/11/2026), the last only 1,577 miles after an oil change. Hyundai TSB 23-EM-008H sets the failure threshold at 1 quart per 1,000 miles for all gasoline engines. The dealer twice billed Hyundai operation code 21000FCC, which that bulletin defines as payable only after an initial oil consumption test result of NG (failed). Two combustion chamber cleanings were performed at Hyundai's expense (1/2026 and 5/2026). Neither resolved the consumption. On 5/14/2026 the dealer submitted a request to Hyundai Motor America to replace the engine. Hyundai denied it verbally and has provided no written decision, case number, or reason. This is our family's primary vehicle and remains in service. I must check the oil weekly to keep the engine from running dry. Complete dealer service records are available.Read more

The vehicle suffers from recurring, sudden loss of motive power and transitions into engine "limp mode" while driving in active, heavy traffic. This severe drivability defect has occurred on four separate occasions under Diagnostic Trouble Code (DTC) P00AF00 (Turbocharger/Supercharger Boost Control "A" Module Performance) and related boost/MAP faults (P0234). During these episodes, the vehicle abr
... uptly loses acceleration capability without warning, creating an acute collision risk when navigating highway traffic and intersections. The turbocharger assembly has required replacement three separate times due to recurring oil contamination from the engine crankcase. Despite meticulous maintenance (documented synthetic oil changes every 3,000–5,000 miles since new), the manufacturer and dealership have repeatedly blamed peripheral turbo components rather than diagnosing or repairing the root cause (I suspect excessive engine crankcase pressure/piston ring blow-by based on the significant oil deposition on the turbo, map sensor, and pooling in the intake line).Read more

I have a 2017 Hyundai Tucson with a 1.6 turbo engine, and I have been experiencing massive oil consumption. Oil is coming out of the tail pipe with occasional big puff of smoke out of the tailpipe. Skipping and hesitation during acceleration, rough cold start, I have previously had the check engine light on with a multiple misfire code. I changed the plugs and the coils, and it did not resolve the
... problems. I then took it to the mechanic, and he told me that the car has to go to Hyundai because these are known problems with my particular motor. I took it to Balise Hyundai in Hyannis Mass. and was told that they know about these motor issues but could not help me because the engine light was not on.' If the light comes on, then bring it back and we will check it out'.I was then told that any work performed would be my responsibility to pay for it out of my pocket. If it a known problem by Hyundai, then I think that a recall or something should be posted so customers are not stuck with a very big service bill. Any help to get my vehicle running the way it was designed to would be greatly appreciated. Apparently, there are no recalls or campaigns about these issues on my vehicle even though they are well known to HyundaiRead more

My 2026 Hyundai Palisade (Calligraphy trim) received the software remedy associated with Hyundai Safety Recall 296 / NHTSA Recall 26V160. Prior to the recall update, the powered second- and third-row seat-folding switches operated with one press, after which the seat completed its movement automatically. Following the recall software update, Hyundai changed the controls so that the operator must c
... ontinuously hold the switch for the entire duration of seat movement, and releasing the switch immediately stops the seat. I understand that the recall was intended to address occupant/object detection associated with powered seat movement. However, I am concerned that Hyundai's remedy eliminates significant functionality rather than correcting the underlying detection system while preserving the vehicle's original power-seat operation. I purchased the vehicle with one-touch power-folding seats as an advertised feature. The recall remedy materially alters that functionality and also disables or restricts other powered-seat functions that were present when the vehicle was sold. I request that NHTSA review whether Hyundai's remedy for Recall 26V160 is an adequate and appropriate permanent remedy, and whether Hyundai should instead be required to develop a corrected seat-control system that safely detects occupants and obstructions while restoring the vehicle's original one-touch power-folding functionality.Read more

Please keep in mind that I am not a mechanic and only a consumer so my specific knowledge of vehicle systems is limited. The vehicle is available for inspection upon request. On July 9, 2026 while reversing out of my sloped driveway my Hyundai Santa Fe Calligraphy Hybrid conducted a sudden, uncommanded emergency brake stop without warning or cause. This occurred one week prior as well on an unkno
... wn date. The system appears to misinterpret the angle of the incline and encroaching tall vegetation as a solid obstacle. This uncommanded malfunction caused a rapid deceleration that directly caused and exacerbated my post concussive syndrome, cervical strain, occipital neuralgia, hyperacusis, and noxacusis, requiring treatment at an Urgent Care clinic on Saturday July 11; the unresolved defect poses an immediate crash and bodily injury hazard. I am going to also need pain management therapies. I attended an appointment at the McGrath Hyundai of Cedar Rapids on Monday July 13 for assistance with this among other things that were occurring with my vehicle. I also have been reported experiencing an interconnected systemic electrical failure, including dashboard cluster loading lag, a complete failure of the Head-Up Display (HUD) to register speed limits, and intermittent green color distortion on the blind-spot turn signal camera display, which shares the camera network used by the reversing safety systems. These issues began around the same time as the sudden emergency braking. I am unsure if they are related however it would make sense. They did not fully conduct the tests necessary to locate the problem as a simple diagnostic scan will not do that. The sensor calibration might be off among other causes. The dealership did not look at the EDR to determine the history of this emergency stop occurring. I am currently working with a Hyundai Corporate investigator whom their team agreed for my vehicle to be inspected by a field engineer. I am currently awaiting their call.Read more

My 2017 Hyundai Santa Fe, purchased new from Lynnes Hyundai in February 2017, has approximately 93,000 miles. The vehicle previously developed a significant oil-consumption/engine problem that was diagnosed by Hyundai, and Hyundai replaced the engine with a remanufactured engine. Approximately two weeks after the engine replacement, the check-engine light illuminated and DTC P1326 was identified.
... The dealership replaced the knock sensor. Approximately two weeks later, the check-engine light illuminated again with a recurring P1326 condition. The vehicle is currently at Lynnes Hyundai and has been there approximately three weeks while they attempt to determine the cause. Hyundai Techline is involved. Prior to the current repair visit, while traveling approximately 60 mph, the vehicle experienced a very forceful hesitation that jerked the vehicle. I immediately slowed down and pulled onto the shoulder. The vehicle continued to hesitate intermittently while I drove slowly to safety. I was concerned that the vehicle could lose power or shut down while I was driving at highway speed, creating a risk of a crash. The recurring P1326 condition has been confirmed by the Hyundai dealership. The vehicle and engine have been inspected by Hyundai/Lynnes Hyundai multiple times, including after the engine replacement. The current recurring condition has not been resolved. The check-engine light is the warning lamp associated with the current condition. I do not know the underlying cause of the recurring P1326 condition; Hyundai is currently attempting to diagnose it.

My wife was driving my SUV while I was a passenger. We were in the left lane, and put the left turn signal on while traveling south bound approaching an intersection to take a left turn (traveling approximately 3-5 Miles Per Hour and slowing) at the traffic light (traffic light was green). There was a car in front of us that had stopped waiting for oncoming traffic to clear and make the same left
... turn onto the same road as us. While traveling in this lane we hit a deep pot hole (not very visible while driving), just as we were approaching the vehicle stopped in front of us. When hitting the pot hole, our SUV seemed to leap forward a bit and when the brakes were applied to slow and stop, the braking system failed (appeared to freeze) and the brakes did not work, and because the braking didn’t work, our vehicle hit the car in front of us. Prior to and after hitting the pothole, no audible warning sounds or visible alerts appeared and no emergency braking was activated. The airbags in our vehicle never deployed. Our safety (my wife and I) as well as the safety of the 2 passengers in the other vehicle were at risk as we all could have been injured in the accident. As we needed the vehicle for transportation, we immediately began filing all the necessary police and insurance reports and brought our vehicle into an Auto Body Repair Shop to be repaired the next day. During the repair work, some of the responsible components may or may not have been replaced and the Auto Body Repair Shop also had all the car sensors recalibrated by a 3rd party, which is why we did not bring the car to a dealership to evaluate. To the best of our knowledge, the manufacturer, the police and the insurance company did not inspect the vehicle. We are not experts, but hitting a pothole might be considered an edge case, so I’m not sure that a dealership would have tried or been able to replicate the issue.Read more

My wife was driving my SUV while I was a passenger. We were in the left lane, and put the left turn signal on while traveling south bound approaching an intersection to take a left turn (traveling approximately 3-5 Miles Per Hour and slowing) at the traffic light (traffic light was green). There was a car in front of us that had stopped waiting for oncoming traffic to clear and make the same left
... turn onto the same road as us. While traveling in this lane we hit a deep pot hole (not very visible while driving), just as we were approaching the vehicle stopped in front of us.

My cameras (front and back) show blue or green signal error screens intermittently. Dealer was not able to replicate, so basically told me to bring it back when it happens all the time. Google search told me that this is a widespread problem, some dealer somewhere must have been able to replicate the issue. Unable to use cameras to monitor for traffic and/or pedestrians. A few examples of when

Pulling into parking space, front goes to green screen about half way. Backing out of parking space, green screen.Read more

I am writing to file a formal complaint XXX regarding a severe safety defect on my 2023 Hyundai Palisade. On XXX, in [XXX] while driving under normal operating conditions, the sunroof glass spontaneously exploded with a loud noise resembling a gunshot. There was no vehicle ahead of me, no overpass overhead, and absolutely no external object or road debris struck the vehicle. The glass shattered
... violently upward and outward, which is a clear physical indicator of a spontaneous thermal or pressure-induced failure caused by a manufacturing defect, rather than an impact. As you are aware, spontaneous sunroof shattering is a heavily documented issue across 2023 and 2024 Hyundai Palisade models. Numerous identical complaints have been filed with the National Highway Traffic Safety Administration (NHTSA), pointing to a known defect in the tempering or structural stress of the panoramic glass panels. I have attached photos and a video of it still making sounds in the photo, you can also tell it is bubbling upward. This vehicle is well within its 5-year/60,000-mile New Vehicle Limited Warranty period. This failure represents a severe, sudden compromise of passenger safety, and I expect Hyundai to honor its warranty obligations. I demand that Hyundai Motor America authorize a full replacement of the sunroof glass, a thorough cleaning of the headliner/cabin to remove microscopic glass shards, and a complimentary loaner vehicle while the repair is being completed. I look forward to your immediate response and prompt resolution to this safety matter. Sincerely, [XXX] and [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)Read more

On 6/12/26, the engine had a sudden, catastrophic failure that caused a life-threatening hazard on a 2-lane highway in a remote mountain grade with no shoulder. Prior to this incident, the forward collision system had falsely gone off several times in dark or rainy conditions when there was no actual hazard or oncoming traffic on the road, which is very distracting and dangerous. Hyundai is no
... t abiding by the terms of the federal class action lawsuit settlement, refuses to replace the defective engine, and is generally a danger to the public. What is the NHTSA going to do the next time a Hyundai catches fire and causes a catastrophic disaster in Southern California? I was fortunate the engine didn't catch fire...it was lightning-hot when I opened the hood a full 30 minutes after the breakdown. This has a Nu series MPI engine...there are 5 known classes of Hyundai/Kia engines that fail without warning and the company is still getting away with endangering drivers, refusing to replace or reimburse. I have a 10k lien on this vehicle and my livelihood is at risk because of Hyundai's negligence and disregard for the law. My stalled vehicle could have caused a deadly accident when it failed had another driver failed to see it blocking the road. This is happening to millions of Hyundai owners and we're not getting the recourse we were promised. My VIN was excluded from recalls and class action, yet it has the same exact dangerous engine defect. Please investigate the Nu 2.0 MPI engine series if this hasn't already been established as an additional unsafe configuration. It would be in the interest of public safety if Hyundai went out of business; the company's manufacturing is a danger to society and Hyundai doesn't care as long as they continue to profit from consumer hardship and suffering.Read more

Incident date: Jul 24, 2026
The instrument cluster malfunctioned suddenly leaving the control panel completely black (no odometer, speedometer, speed range, turn signal indicators, etc.). The driver was therefore unable to know what speed they were driving, how much fuel remained, and lacked any sort of signal that turn signals/blinkers were on or off. It was unsafe to drive and impossible to accurately comply with legal spe
... ed limits. Local Hyundai dealership inspected the car and confirmed that the cluster had to be replaced, which they did (required 11 total days of being unable to use the car).Read more
