Equipment Problems of Hyundai Sonata - part 1

The cars fan is constantly running even when the car is cool. I think it has to do with the itms I contacted the dealer and they said there’s nothing they can do about it this happens every time the vehicle is started even when I am parked. The fan is constantly running at 100%.

I was driving my vehicle on multiple occasions in which the car started to alarm and say, "check charging system" at which point the car stopped all together. Also, when the cruise control is engaged, it will turn off automatically. It doesn't matter the speed the cruise control is set at, it will turn off.

My 2016 Hyundai Sonata is experiencing severe oil consumption due to a known Hyundai engine defect. The engine burns oil rapidly and loses more than a quart between oil changes. This creates a safety hazard because the engine can stall, seize, or fail while driving. The Hyundai dealership did not perform the official Hyundai oil-consumption test. They only checked the dipstick, noted the oil was low, and submitted a request for a paid combustion cleaning. Hyundai declined to pay for the cleaning, and the dealership is refusing to perform the required oil-consumption test unless I pay $750. 00. Hyundai corporate also refused to authorize the test, stating the vehicle is out of warranty, even though this is a known engine defect affecting many Hyundai vehicles. Without the official test, Hyundai will not review the engine defect or consider a goodwill engine replacement. This is a safety issue because the engine can fail without warning. The dealership and Hyundai are refusing to perform the required diagnostic test unless I pay $750, and refusing to review the defect without that test.

The horn on my vehicle completely stop working. There were no alert messages and I found out that it wasn't working when I needed to use it. I was driving 55 miles per hr in a highway and another vehicle was about to switch lane to merge into my lane and driver did not see me and almost got into an accident. When I try to use the horn to alert tge other vehicle, horn did not work. It still doesn't work. Took my vehicle to millenium hyunday dealership in hempstead, NY and was told by service advisor that horn is only covered up to 60,000 mike's because is an electronic feature. I disagree with that assessment and believe this is a safety feature that needs to be reevaluated.

I wanted to report the failure of my rear camera and/or the electrical circuit that is tied to it. It's my understanding that Hyundai has issued multiple recalls across different years/vehicles for issues in this area. My 2019 Sonata is not included in those current recalls. I was without my vehicle for a week and was charged over $1600 to repair. The issue was diagnosed and repaired by an independent mechanic. When they system failed numerous error lights/warning went off and continued to cycle thru (plus beeping). I wanted to report this in hopes of continued pressure on Hyundai to add this model/year to their recalls.

I am reporting a serious safety issue involving a 2017 Hyundai Sonata plug-in hybrid (VIN: [xxx] ), originally purchased in California. While driving at approximately 70 mph on a highway, the vehicle suddenly lost all propulsion without warning and rapidly decelerated. This created a dangerous situation with surrounding traffic and put me and my family at risk. I had to quickly maneuver to the shoulder to avoid a potential collision. The vehicle was towed to an authorized Hyundai dealership in utah, where it was diagnosed with a failure of the high-voltage battery system. I was informed that the battery requires replacement. This type of sudden loss of propulsion at highway speed is extremely hazardous and could result in a crash, injury, or fatality. There were no prior warnings indicating an imminent failure of this severity. Given the safety risk associated with unexpected loss of propulsion, I am concerned this may represent a broader issue affecting similar vehicles. The vehicle is equipped with an interior camera, and video of the incident can be provided if needed. I respectfully request that this issue be investigated as a potential safety defect. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2026 Hyundai Sonata limited hybrid first owner. The sunroof above the driver's seat exploded while I was driving 70mph on the highway. Sounded like a gunshot. It was completely shattered but thankfully did not rain down on me. Local Hyundai dealer inspected it and warranty denied from Hyundai due to "caused by an outside influence. " I did not see or hear any rocks or debris.

Consuming oil a quart every 2-3 weeks Sonata Hyundai in 2000 miles 3 quarts of oil were used. What happens when the motor locks up from be extremely low on oil. Possible accident! I cannot expect my wife to be checking the oil level every time she drives.

Code p1326 unable to accelerate, drive past 1st gear and knocking noise in engine area engine could stall out or lock up if problem is not fixed 3/14/2026- started engine light blinking warning light also code p1326 has had recalls for this particular car brand.

I was notified of a recall on my from vehicle by Hyundai via email some time in March of 2026. The message said mentioned my vehicle may have a defective/worn purge control check valve that would cause the fuel tank to deform. Potentially leading to a release of fuel over time, which then could ignite. Nhtsa recall #25v796000 my car showed now signs of problems, but I brought it into a Hyundai dealership on March 13th where they confirmed my vehicle had the issue. They said the situation required I not drive my vehicle and gave me a rental in the meantime. I assumed it would be a simple swap of the fuel tank and everything would be fine. I was offered a buyback from my Hyundai claims manager over the situation, but I figured since its a simple fix, I'd keep my car and have it fixed. Two weeks went by with no update from the dealership, so I walked in for answers. Turns out, the subframe of my car has been damaged by the expanding fuel tank and they are still waiting for updates from Hyundai on how to proceed as they themselves don't know how to fix my vehicle. My Hyundai claims manager did not mention this when we talked over the phone and he offered a buyback. None of their recall notices mention structural damage anywhere or even as a possibility. I asked the dealership again on April 1, 2026, and they are still waiting on guidance on how to proceed. Neither does my Hyundai claims manager handling this situation on their end.

Vehicle started then stalled requiring tow. No initial illumination of warning lamps or messages. Findings upon inspection by independent service center: multiple cylinder misfires (p030100, p030300, p030400, p030200, p030000) and excessive debris buildup on vvt sensor screen. Car uses excess oil- a minimum of 3 qts per 600 miles. No warning lamps or messages occur when car is excessively low on oil.

Driving home and heard what sounded like a gun shot. Upon arriving home we found the moonroof glass had exploded/shattered. Took pictures/video to document. Found online that there have been reports of similar instances happening dating back to 2011 and newer vehicles. Have called dealership to see what next steps are to have repaired as a warranty issue but service department is closed until Monday morning 7am.

Sun roof flew off while driving, the metal framing was twisted and dent. Sun roof was closed at the time. Pictures were sent to insurance company but no one has looked at it yet. No warning. Sun roof was working properly.

Here is your updated review with that included: ? I am very disappointed with Hyundai motor America and the service I received at Hyundai of renton. I own a 2017 Hyundai Sonata and received a letter about a required software update and ignition cylinder protector due to known theft issues. I went to the renton dealer for the recall service. They performed the software update and were supposed to install the ignition cylinder protector. Unfortunately, my car was later stolen because of this exact issue. The ignition was damaged during the theft, and I had to replace it myself just so I could drive the car. When I returned to the dealer, they refused to install the ignition cylinder protector, saying the ignition was broken. It was broken because of the theft — which happened due to Hyundai’s known defect. After the recall software update, my key fob also stopped working properly. I went back to the dealership, and they refused to fix or properly reprogram my key fob. On top of that, the service manager, john, was very rude and unprofessional. This has been the worst experience I’ve had with a vehicle and a dealership. Because of this situation. Very disappointed.

My car was broken into and they broke off my door handle and took out ignition parts, a police report was done.

Was driving car and it went completely hot. Towed to a dealership and they said was not drivable and that the radiator support and radiator hose needs replacing and eventually the drive cv left and front will need replacing or I will be stranded on side of road.

While driving the vehicle the other night, the cars electrical system completely shut off for a few seconds before popping back on. The whole car inside and out went completely black. It was around 10pm on a dark country road. I had the seat heater on high and the defrost on high because it was cold. It appeared to happen when the auto high beams were supposed to engage. Instead of them engaging, the whole cars electrical system just shut off. No headlights, no instruments, interior lighting, console display, nothing worked. The car was in battery mode at the time, and it sounded like the whole car just shutoff. I took my foot off the accelerator wondering what happened, and before I could understand what was going on, everything came back on. It did not prompt me to start the vehicle again. The auto on/off brights never worked like they were supposed to again either. I had to manually engage and disengage them. Thankfully it was just me on that stretch of road going 30mph at the time or it could have ended badly.

This car is becoming more of a headache than it’s worth. Turned the car on, my car started shaking and my check engine light came on. Then I got this message “a possible condition with your engine control system has been detected on a 2017 Hyundai Sonata”.

My 2012 Hyundai Sonata recently had an engine replacement completed under a Hyundai recall. Immediately after the recall repair, the vehicle began shaking while driving, produced a burning smell, and the air conditioning stopped working, none of which occurred prior to the recall repair. These symptoms started immediately after the engine replacement, indicating a possible improper or unsafe installation. I believe the vehicle is unsafe to drive due to the burning smell and shaking. I contacted Hyundai customer service and was told the issue must be resolved with the dealership. However, the dealership has refused timely inspection, has dismissed my safety concerns, and has declined to provide a rental or loaner vehicle, leaving me without safe transportation. This is a post-recall safety issue, and I am concerned about the risk of fire or mechanical failure due to the burning smell and vehicle instability. I am requesting this issue be formally investigated.

Both rear doors will not open. The door locks stopped functioning so we are not able to open and close both rear back doors. In addition, the right rear door window stopped rolling up and down.

Will be driving the car and suddenly hear a beep. Then the dashboard will flash with the abs light engine light tire pressure light check blindspot sensors, forward collision sensors. Once all the lights appear on the dashboard, I can no longer accelerate. I’ve cleaned the throttlebody. I’ve replaced the gas pedal and it’s still kicking back the same code it still does it the same identical thing. It’s given out on me three times since December with an infant in the car. We are now in February.

• I experienced trouble with my splash guard being damaged from hanging and scraping the ground about a month after purchasing the vehicle. Also, my hood paint started chipping after a recent cold front experienced in my state earlier this year. Yes it is available for inspection upon request. Regarding the splash guard, not applicable. • it’s was very inconvenient to drive with a portion of my car scraping the ground. I had to be more mindful of my driving in the higher speed limit areas incase the splash guard detached. I had it re-attached multiple times. Regarding the chipped paint, not applicable. • it it counts, for my splash guard, during a servicing, I asked Hyundai to re-attach it. For the chipped paint, no. • the splash guard has during a past servicing. The chipped paint is more recent so it hasn’t • no. Splash guard, a month after purchasing vehicle. The chipped paint, earlier this year, January-February 2026.

I had recall 162 - engine replacement completed in 2024 , now I have fuel leak at high pressure fuel pump, the pump that is a component of the engine has now failed which was installed during the engine replacement which can cause a major fire.

My vehicle has a documented excessive oil?consumption defect. After a 1,000?mile oil?consumption test performed by a Hyundai dealership, the engine was found to have consumed 2. 8 quarts of oil, which is far above normal and poses a safety risk. The dealer referenced TSB 23?em?008h and recommended a chamber cleaning but could not guarantee it would resolve the issue. Hyundai motor America declined to cover the repair and refused to escalate my case. This level of oil consumption is consistent with known theta ii engine defects that have led to engine seizure, stalling, and fire in other vehicles. I am reporting this as a safety concern due to the risk of sudden engine failure while driving.

I was involved in a low-speed collision at a residential intersection after stopping at a stop sign and beginning to proceed. Going under 5 mph, I braked immediately, but contact occurred. Despite relatively minor front-end damage, the driver steering wheel airbag and driver knee airbag deployed. The passenger front airbag did not deploy, and no side or curtain airbags deployed. There was no significant intrusion into the engine compartment or passenger cabin. I am submitting this report due to concern that the driver airbags deployed in a low-speed impact that did not appear severe enough to warrant deployment. Pictures attached.

Experienced sudden unintended acceleration causing my car to speed up, lose control, and crash into the vehicle in front of me.

There was no accident . Airbag light on the dash, on the driver side, remains on at all times. The airbag indicator on the passenger side says off. Dashboard has completely cracked, both sides and the center. Unknown incidents- I don’t know of any incidents.

Vehicle: 2016 Hyundai Sonata VIN: [xxx] while stopped in traffic with my foot firmly on the brake, my vehicle begins to accelerate before I release the brake pedal. This is not normal “creep” — the engine increases rpm and the vehicle moves forward as if the accelerator is being applied, even though it is not. This condition has occurred multiple times and creates a serious safety risk. The vehicle surges forward, sometimes 20 mph, unexpectedly and has almost caused several collisions. This rapid acceleration can easily cause a collision with a pedestrian or the vehicle in front of me. The onboard diagnostic system repeatedly reports a camshaft position sensor fault. The sensor has been replaced, but the problem returned, indicating the issue is not the sensor itself but a deeper engine or electronic control malfunction. Because this vehicle uses electronic throttle control, I am concerned the engine control module is misinterpreting throttle and brake inputs and failing to properly apply brake-throttle override. The vehicle is effectively accelerating against the brake. This is a dangerous and unpredictable condition and represents a potential defect in the throttle/engine control system. This is clearly a safety-related issue that warrants investigation before it results in a serious crash or injury. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle’s dashboard continuously displays a “hood open” warning even though the hood is fully closed and securely latched. The hood has been physically inspected and confirmed to be closed, yet the warning persists. The issue appears to be related to a faulty hood latch sensor or switch, which is part of the hood latch assembly. The warning is inaccurate and does not reflect the actual condition of the hood. I am requesting that NHTSA review this issue for potential investigation, as it may represent a defect in the hood latch sensor system on the 2017 Hyundai Sonata that could affect multiple vehicles and pose a safety risk.

I was driving my 2014 Hyundai Sonata in a rural area when smoke suddenly entered the cabin from the engine compartment. Two bystanders waved me down, alerting me that they could see fire underneath the engine compartment. I immediately stopped the vehicle, turned it off, and exited safely. I attempted to contact 911, but reception was poor. The fire spread from the engine compartment and engulfed the vehicle, producing thick smoke that created a serious safety risk. Emergency services arrived approximately 15 minutes after being notified and extinguished the fire. The vehicle burned for approximately 30 minutes in total resulting in total loss. There were no warning lights or messages prior to the fire. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives beyond the fire report. It was towed and is being stored on private property awaiting investigation.

I own a 2021 Hyundai Sonata 1. 6t, which has an open NHTSA safety recall (25v796000) related to fuel tank pressurization and fire risk. I brought the vehicle to an authorized Hyundai dealership due to a check engine light, reduced performance, and dtc p14ee, which aligns with the recall condition. The dealership refused to treat the concern as recall-related unless I paid a diagnostic fee and later attempted to reclassify the issue as a customer-pay fuel pump repair. During this visit, the dealership replaced a fuel system sensor without my authorization, which I did not approve or consent to. The dealership has not provided documented test results explaining how the recall condition was ruled out and has not documented recall inspection on the repair order. I expressed that I do not feel safe driving the vehicle due to the fuel system recall and drivability issues. The dealership also refused to provide alternate transportation. I am concerned the recall is not being handled in compliance with NHTSA requirements and that unauthorized repairs were performed while attempting to shift a recall-related condition to the customer. I am requesting review of recall handling and dealer compliance.

Oil pressure sensor failure caused oil to leak into the injector harness damaging components and engine shutdown. Because this was a sudden engine shutdown and safety-related loss of motive power caused by an oil pressure sensor failure this presents a safety risk.
