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.

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.

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.

Component or system involved and availability for inspection: the issue involves the transmission / drivetrain system. When I entered my VIN on Hyundai’s official dealership website, a safety recall related to the transmission appeared. I took a screenshot of this recall. When I later contacted Hyundai motor America and spoke with my assigned case manager, I was told that no such recall existed for my VIN. A few days after that call, the recall no longer appeared when checking the VIN online. The vehicle is available for inspection upon request. How safety was put at risk: a transmission-related safety recall presents a risk of loss of power, inability to accelerate, or sudden mechanical failure, which could increase the risk of a crash, especially during normal driving conditions such as merging, accelerating, or driving at highway speeds. The uncertainty and inconsistency regarding whether a safety recall applies to my vehicle has put my safety and the safety of others at risk. Confirmation by dealer or service center: the problem has not been repaired by a dealer, as Hyundai denied that a recall existed despite it previously appearing under my VIN on their official website. Independent service centers that recently serviced the vehicle did not identify or report any transmission warnings or failures. Inspection by manufacturer or others: the vehicle has not been physically inspected by Hyundai for this recall issue. My only interaction with the manufacturer was a phone call + email with a Hyundai case manager, who stated that no recall applied to my VIN. Warning lamps, messages, or prior symptoms: there were no warning lights, messages, or symptoms prior to this issue. The vehicle recently received routine maintenance, including an oil change, tire balancing, and tire rotation, and none of the service providers reported any problems or concerns related to the transmission or overall vehicle condition. I am 34 weeks pregnant with no way to the hospital.

Vehicle without warning will start to jerk then go into “limp” mode. Pressing on gas pedal makes the revving noise but with not physical movement made. This has happened on multiple occasions (13 times in 4 months) including in the snow and on the interstate while driving at 70mph where no shoulder is available to pull over. Car was taken to dealership 3 different times with no actual diagnosis, tests were ran all 3 times with nothing. Eventually the 3rd time at the dealership I was told the transmission was being replaced although they were not sure what actually caused the issue (this is written in the service report by the rep/mechanic). Car remains unsafe and unreliable. Livelihood of myself, family and other drivers is at risk everytime I put the car in drive due to this mechanical issue. No warnings no power no fix.

Excessive oil consumption. I am routinely getting notifications of low oil about 1,000 miles before the oil change is due. When I bring it in for an oil change it is nearly empty. No signs of leaks anywhere.

Brakes seize up while driving and then cannot move the vehicle. This causes a dangerous situation while driving and then breaks lock up and cannot move car even though vehicle is on and then stopped for a stop light. Car must then be turned off and sit for about 30 minutes so it can unseize and when that happens, you can then resume driving and then check engine light comes on. Brake lights were staying on even when vehicle is shut completely off. Abs and esc lights stay on consistently and never turn off. Vehicle brake switch was replaced at carolina Hyundai of high point, nc. So break lights have been repaired. They had to order the stop switch lamp replacement for recall as it was never done and will be fixed in next week. 3 door handles fell off and cannot open the rear driver side door at all. Window electric system won’t let windows go up and down and had to make a latch pull string to open driver door. Passenger door will not open at all and no handle and is a dangerous situation. Break switch not being replaced would have cause an electrical fire and is a complete dangerous vehicle even after being inspected less than a week ago.

1. Dash board has several cracks especially over airbag. 2. The location and severity of the cracks raises concerns regarding the structural integrity of the dashboard during a collision and the potential for obstructed airbag deployment. 3. It has not been inspected. I plan to carry it to the dealer tomorrow. 4. There were no warnings. I just realized the cracks a few weeks ago. I had seen them prior but thought they were part of the design until they became more pronounced.

Noticed there’s a crack on the passenger side dashboard of the car that’s about 12 inches long. From what I read this could cause issues with any possible airbag deployment.

The driver’s seat / passenger seat assembly, including seat rails, mounting brackets, and Smart junction box (sjb) connections if electrical adjustment was involved, completely failed during a crash. The seat lifted off the floor anchors and almost entirely came apart, including both the seat cushion (where you sit) and the backrest, leaving the occupant crushed within the collapsed seat structure, resulting in catastrophic injuries. During the crash, the seat collapsed and disassembled, exposing the occupant to extreme trauma. This caused: •pelvic fracture •broken femur, hip, and back •collapsed lung and punctured liver •foreign object from the seat mechanism punctured pelvic bone the failure directly contributed to life-threatening injuries that would not have occurred if the seat had remained securely anchored. The malfunction posed an immediate risk of death and permanent disability. Not yet reproduced under controlled conditions. The incident has been documented by police and medical personnel. The vehicle is currently in a tow yard, and we have not had access to it, but it remains available for inspection by Hyundai, NHTSA, or a qualified service center police: yes, crash scene documented. •insurance: we are unsure whether the insurance company has inspected the seat. The vehicle remains in the tow yard and has not been repaired or altered. •manufacturer (Hyundai): not yet inspected; formal inspection requested. The vehicle and seat are preserved and ready for inspection by Hyundai, NHTSA, or other qualified representatives. There were no warning lamps, messages, or prior symptoms of seat failure. The seat functioned normally prior to the crash, and the malfunction occurred only during the impact, demonstrating a sudden and catastrophic failure under crash conditions.

At about 30mph the sunroof suddenly flew of of my car and almost hit the car behind me thst had to avoid the flying part, for a good luck it didn’t cause a major accident because I was about get in a busy highway and this hazard could’ve caused a major ctash envolvimg multiple cars, the vehicle behind me has a dashcam that recorded the event. For god nobody got injured.

Nhtsa: #25v796000 recall: #286 2020-23my Sonata (dn8/dn8a) fuel tank issued on 11/18/2025 and there is no remedy yet for this issue. Hyundai of ocala has not issued me a loaner car. What am I supposed to do? it’s been over a month since the recall was posted and still no remedy. I’m concerned for mine and my families safety. This car is our only means of transportation. I need a solution.

Cruise controldoesnt work due to design defect dirt getting in and stopping the function.

New battery keeps dying, car not starting and when it does start it shuts off when I brake. Oil light on after I already put oil in the car.

The vehicle dashboard is severely cracked. It doesn’t appear to be from wear and tear.
