Equipment Problems of Hyundai Sonata - part 2

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.

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.

We think there’s an issue with the abs module and wheel speed sensor because we started having a problem where the brakes wouldn’t work or would stutter. The car would shake real bad it would make an awful grinding sound but normally only when trying to stop at higher speeds or long braking. The only thing that made it stop was to unplug the abs but then other parts of the car stopped working like the speedometer and the sensors around the car. So we got the abs replaced but the new one started doing the same thing. We did some research and it sounds like the same issue Hyundai is having with the palisade. The incident that made us get it replaced to begin with was were driving down the road and we got to a traffic light but when we tried to brake they just didn’t work so we drove through the red light luckily the one person who was supposed to be going saw us and didn’t pull out in front of us so we didn’t get hit. We haven’t taken it to the dealership yet but my sister who teaches automotive repair at the community college is the one who diagnosed it so she said we should report it here so maybe it won’t happen to anyone else. Before we had the brake issue we were having problems with basically everything on the dash not working randomly. We’d be driving down the road and the speedometer and the outside sensors and the gas gauge and the traction control all would go out at the same time it’s the same stuff that went out when we had the abs unplugged so it seems that might be related.

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

My car has a severely cracked dashboard which could cause reduced structural integrity and an increased risk of debris and shrapnel being deployed in the event of an accident. The dashboard is a structural component designed to help absorb and distribute some of the forces in a collision. Cracks can compromise this ability to perform this function potentially increasing the force experienced by the occupants and the other parts of the vehicle. It can also cause increased risk of debris and shrapnel. During a collision the cracked dashboard may break apart more easily causing sharp or jagged pieces to become projectiles inside of the cabin these fragments can pose a serious injury risk to occupants. It can also result in impaired airbag deployment. Many vehicles have airbags in the dashboard a severely cracked dashboard could obstruct or improperly deploy airbags for example the airbag may not fully deploy reducing its effectiveness and the dashboard may puncture or otherwise interfere with the airbag as it inflates creating additional safety hazards. Cracks may expose sharp edges or materials under the dashboard which could harm occupants during a collision, especially in areas where passengers may come into contact with the dashboard. A cracked dashboard could also cause a compromised electrical system dashboards house numerous electrical systems, sensors, and controls cracks could indicate underlying damage to these components. In a collision, these systems may fail or behave unpredictably which could further reduce safety features. Cracked dashboards present a significant risk during a collision and should be addressed by the manufacturer promptly to ensure its customer safety.

P0471 error comes up off and on, this is recall related but the dealership refuses to address it. The seatbelt has to be clicked 2x in order to stick. Happens with driver side.

Coolant is leaking again after being fixed at a Hyundai dealer. If I don't fix it, my car will overheat and catch fire in the middle of a public road. My warranty has now expired, so I'll have to pay for the repairs myself. However, this problem is a design flaw, not related to the car's age or mileage. Hyundai should fix this problem. I'm not the only one; there are a lot of people complaining about this.

My 202 Hyundai Sonata is involved in the current Hyundai fuel system recall. On 10/26/25 the fuel tank expanded and caused three explosive "boom" sounds inside the vehicle while I was driving with passengers. The backseat began heating and rising upward due to fuel tank swelling. The tank became pressurized, hissing, bubbling, and would not accept fuel. The vehicle became inoperable. The car has now been at Hyundai of camelback since 10/27/25 (30 days). Hyndai corporate has repeatedly delayed providing a remedy and keeps telling me they "need another week". I have received no repair plan, and no decision. This violates the requirement for a timely recall remedy. The defect caused structural damage and created a serious safety hazard. ".

On the highway, my 2015 Hyundai Sonata suddenly began making a squealing or metallic rattling noise. At first, I thought it might have been something loose inside the vehicle. Within moments, the check engine light began blinking, followed by several additional warning lights and a pronounced knocking noise from the engine area. Immediately after the warning lights appeared, the vehicle entered a reduced-power “limp mode” and began rapidly losing speed, even though the engine was still running. Because this occurred at highway speed while surrounding traffic was traveling normally, I had to pull onto the shoulder to avoid being struck. This created a significant safety hazard. I was stranded for approximately 45 minutes on the shoulder, at risk of being struck by other vehicles passing at high speeds. A tow truck arrived before the highway patrol, and the vehicle was towed home. When I returned home, my code reader pulled two versions of diagnostic code p1326, which is associated with potential engine bearing failure in Hyundai theta ii engines. The issue has since been inspected by the dealership, who confirmed the presence of the p1326 code. The vehicle is currently available for further inspection upon request. There were no prior symptoms that I was aware of leading up to the incident other than the brief squealing/rattling noise and the sudden warning lights immediately beforehand. The failure happened suddenly and without warning, causing an immediate and unexpected loss of speed and creating a dangerous situation on the highway.

The paint started peeling off in large sections.

No incident to report. Vehicle not regularly driven in about 5 years, other than to keep battery charged. But charge not hold. Have to charge battery again the next day. This is to reporting a crack in the passenger side dashboard where airbag is located.

While driving around 20 mph my cars rpms will rev and my car will take off then my automatic breaks will kick on and today around [xxx] I was going under 25 mph and there was a car in-front of me and it really scared me as I went to hit the breaks my car already did. My car has done this twice now, both on residential roads. The first time I figured it could have been a me error but now I know this is something seriously wrong with my vehicle. I have had my car for years and I know my car and it never just takes off how it has been there’s always a delay when I go to accelerate. This is very concerning and I’m scared to drive my car now.

Rear view camera stopped working about 6 weeks ago. Mechanic says need new camera which would cost about $500 labor and parts. Contacted dealer and Hyundai corporate to report and complain. Many other Hyundai vehicles have same problem with rear view camera but they are included in a recall campaign. Mine is not. Mechanic said the repair requires new camera and wireing harness. Hyundai case number is 41861577.

The problem with my vehicle is a failure of internal engine components, specifically a known defect in the piston rings of the Hyundai theta ii engine. This failure causes excessive oil consumption, which is burned internally. The internal engine components have failed, leading to a widely documented defect in the Hyundai theta ii engine. The primary symptom, which began to get serious around 80,000 miles, is the constant need to add oil to the engine every two weeks. If I do not do this, the low oil warning light illuminates on the dashboard, serving as a continuous alert of the problem. This failure was officially confirmed by an authorized Hyundai dealership. About two weeks ago, they first documented that there were no external leaks on the vehicle. When I returned because the oil had been consumed again, they performed a new diagnostic, for which I paid over $300, that confirmed the engine is burning oil internally. The dealership, acting as the manufacturer's representative, is the only entity that has formally inspected the vehicle. The situation places my safety and the safety of others at serious risk. First, the oil consumption can lead to a sudden and catastrophic engine failure, resulting in a loss of power and control of the vehicle while in transit. More alarmingly, the guidance I received from Hyundai staff was to simply "wait for the engine to stop working or start making a lot of noise. " as someone who depends on the car for a daily commute, following this dangerous recommendation is an unacceptable risk.

Take. A break warning light is a hazard and distraction and is not accurate at all. I am not a new driver but this id not s safety feature it is such a distraction and is not consistent. I am not going in and out of the lane and even with both hands on the wheel it still goes off about every 90 seconds even at the beginning if some drives after about 3 miles. It is nig consistent and causes you to panic at times when the alarm sounds there is absolutely no way to disarm this. I am [xxx] and do the safe driving course every four years. This is a menace and I do t expect any results but I will not keep this car. Going to trade it in on american car.

This is the 2nd Hyundai I've owned, same year make and model. The first one was totaled due to the air bag deployment. The accident did not warrant the air bag deploying. I should have reported it at the time. I didn't realize that I could and now it's too late. The claim has already been submitted. Now, we have the same exact car and a crack has appeared on the passenger dash. My concern is the airbag. The crack just appeared from nowhere. I do not feel that we should have to pay for a replacement dash. Is this something that can be repaired by Hyundai, as it poses a risk to my 18 year old student driver. My number is 540-686-5624, c. Wills136@comcast. Net.

Filled gas tank up on Friday [xxx] about 10am as leaving boca raton, FL to head north to new port richey, FL. About 30 minutes later the gas mileage said there was only 90 miles left in the tank. Stopped at the next gas station to make sure nothing was leaking, added a little more until it clicked, basically full again. Got to approximately [xxx] near morris bridge in tampa area, the car started to decelerate and then all the engine lights came on and car was shutting off, was able to pull to the left side of the road and looked into the back seat noticed the back seat was rising. Looked under the back of the car and the frame looked like it was pushing up into the backend of the car. Dot was called out to the scene as it appeared the car could have exploded. This could have killed my [xxx] daughter (which was who was driving the car) or other people on the road. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

While driving, my 2015 Hyundai Sonata 2. 0t experienced severe knocking and loss of power due to a ksds-related engine defect. The check engine light was inoperative, and the engine now makes loud noises and emits fumes. Hyundai declined warranty coverage despite known ksds issues. This poses a serious safety concern ( I recently purchased the car and been fixing problems every since).

What the consumer services tried to offer (more information for case)me, instead of a replaced engine that is under my warranty. They have replaced engines before over the mileage as goodwill warranty, but refuse to do the necessary work because of mileages. Ksds is designed for any mileage, and they put a mileage limit on the vehicles warranty, that not just I, but multiple people purchased; where the justice.

The vehicle's hvac (heating) system failed. It stopped producing heat on one side of the vehicle. My mechanic/dealer diagnosed the issue as a broken component within the hvac case under the dashboard, requiring full dashboard removal and a repair estimated at over $3,000. This failure prevents the defroster from working properly, which is a major safety hazard as it cannot clear fog or frost from the windshield. A search of online forums and owner communities shows this is a widespread complaint from many other Hyundai owners, often identified as a failed blend door or blend door actuator, which requires the same expensive dashboard removal to repair.

I have had 3 door handles fall off in the last couple months I think this is safety concern I do not see any recalls. I do see that there is a lot of people complaining about this matter door handles should not be fallen off.

Car has had check engine light on for 3 + years. Have taken it to several mechanics including a Hyundai dealership and none of them can figure out what is wrong. Have replaced water pump, belts x2 in a year (same belt) and thermostat x 3 again (all within 2 years). Dash fuel gage and dash heating/cooling gage are completely erratic. Cruise control does not work. Due to chronic check engine light and mechanics unable to pin point the problem, car has become hazardous to drive. With that in mind, today (9/10/2025) while exiting the high way, car stalled and behaved like it was in neutral. Steering wheel also locked up at this time. Luckily was able to stop. Had to restart car and then it occurred again while driving on a side street at 35mph. The codes that are still popping up are ones that I have spent thousands trying to fix and find the root cause of the problem. What could the issue be if no mechanic can seem to diagnose and fix the issue?.

The car got the 993 campaign software engine immobilizer update and it was locked with the keyfob. It still got stolen. Thieves broke the lock on driver side door which deactivates the immobilizer. Car was found and police report was filed. It is available for inspection. Many Hyundais that have had the immobilizer update have since been stolen. The 993 software update is ineffective.

There was a 2011 Hyundai Sonata hybrid transmission-related shift cable recall, campaign 123, which covered certain 2011-2014 Sonatas (including some 2011-2015 hybrids). The recall addressed the potential for the transmission shift cable to detach from the shift lever pin, which could prevent the car from being fully in park and potentially lead to rollaway.

The vehicle had the antitheft recall service done. On 8/30/25 the vehicle was stolen. It was recovered on 9/1/25 without the catalytic converter. The insurance confirmed it was a total loss. The door lock was tampered along with the engine lock. This was a horrible experience.

The parking assistant camera on the front of the car is loose, which means that the bracket is broke. I took my car into Hyundai and they could not explain to me how it got broke or came loose and this is a safety issue because this helps you park and see what’s in front of you when parking.
