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.

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.

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.

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.

This car has been having white smoke since I got it the smoke coming from the exhaust smells like oil burning.

Not sure . The car has been regulaurly maintenced and one day the emgine complagely seized up going down the road .

I got this car a Hyundai Sonata 2004 about 2 to 3 years ago. At first I didn't notice the problem until a couple months into me having the car I was on the freeway and it suddenly felt like I was out of control of my car and the back end was like swerving like I was pulling a trailer. And ever since then it's gotten worse now my front right tire goes flat randomly. A friend mechanic of mine looked at it and said that it is a suspension he just doesn't know what part of the suspension. This is dangerous because I could lose control of my car I have at any time. That could be detrimental and there is a recall in it seems like almost every other state but utah. For the exact issue that I'm having and I don't think that's right. I've had issues with this car ever since I got it. If you guys could look into this that would be great also this form asks the approximate date that something happened it happens all of the time. To the point where I'm afraid to drive it at all. I also it's gotten so bad that sometimes when I'm going only 35 mph and I hit like a pothole it will severely swerve and I will lose control of my car or if I turn my car I turn my car my steering wheel the right way and I lost control of my car it started swerving and I was on a mountain. .

The vehicle went in for repair at the dealership early July for a check engine light and dtc error code. It was revving high after being driven for more than 20 min or so and wouldn’t get to above 60 mph. Jerky, dangerous acceleration and deceleration seemingly out of nowhere. The dealership replaced the fuel pump which is what they said was causing the error. Today on August 10th, check engine light popped up again with a dtc error code. Weird acceleration and deceleration and general jerkiness when driving. Scheduled service appointment for next week.

What component or system failed or malfunctioned, and is it available for inspection upon request? the engine in my 2017 Hyundai Sonata sport is defective. Oil pressure failed testing, oil contamination was found on the oil pressure sensor and connector, and the vehicle has experienced excessive oil issues. The engine is still in my possession and available for inspection upon request. How was your safety or the safety of others put at risk? the vehicle has gone into limp mode on the highway, which caused a sudden loss of power and created a dangerous situation in traffic. The car also shakes, misfires, and loses power unexpectedly, which could lead to stalling or loss of control at highway speeds. I do not feel safe driving the car. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Multiple Hyundai dealerships have inspected the car. One confirmed low oil pressure and oil contamination at the sensor. Previous visits dismissed the oil warning and charged me for oil replacement instead of identifying the underlying defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes. The vehicle has been inspected by Hyundai dealers multiple times. I also have two inspection reports from the same dealer just two weeks apart with contradictory findings the first showing no oil issue, the second confirming oil contamination and failed oil pressure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. The oil warning light and check engine light have both come on. The vehicle has gone into limp mode, and symptoms have included shaking, misfiring, rough idling, and loss of power. These issues began months ago and have continued despite repeated service visits.

My Hyundai consumes oil and I have to put oil in it every two weeks! also my ignition coils has had to be changed 4 times. Also check engine light just came on code saying catalytic converter or oxygen sensor changed oxygen sensor a couple months ago. I purchased it brand new and as soon as I got over 100,000 miles nothing has been going good since then please help also my paint on the top of the car is starting to peel. Will never buy a Hyundai again.

My starter failed after 35,683 miles leaving me stranded in a parking lot at night. The life expectancy for a starter is between 100,000and 150,000 miles. Hyundai replaced the part at a cost of $1,139 which is way above what it normally costs to replace a starter. The starter is at the dealership and is not available for inspection. Being stranded in a parking lot made me very uncomfortable and what if the starter had failed in a bad section of town. The problem was confirmed by a Hyundai dealership who replaced the part after I had my vehicle towed to their service department. The only ones who inspected the vehicle was a mechanic at the dealership. There wer no warning lamps or messages, but I did notice the car did not start on the first try before the starter failed. 07/29/2025.

There are 2 cracks on the dashboard directly over the passenger airbag that were there when I bought the car and there is another crack that happened some time between yesterday and today. The crack is almost the width of the dashboard. If there is an accident I'm worried about get hit by pieces of plastic dashboard.

My car has had excessive oil consumption for over a year. Hyundai looked at it. Did something to fix it for a couple months and now it’s back worse then ever and they don’t want to do anything about it.

I have contacted the guy that sold me the car he refused to fix the recall which is my motor I need something done , Hyundai won’t honor their recall .

When starting car warning lights came on for abs, aeb, cruise control. Cruise control is locked out and not working due to these warnings.

I started the car, put it into gear and then the breaks wouldn’t work. The car dash said something like check breaks hybrid system failure do not drive. There is not recall on my car but the Hyundai service department doesn’t know how to fix it. This is the second time it’s happened. I’m scared to drive it. Please investigate!.

Steering wheel warning light comes on traction control light comes on. Steering becomes difficult.

Car been burning oil since I got it . I have been taking it back and forth to the dealership they not helping and I’m basically paying a note on a car I can’t even enjoy.

The inattentive driving warning goes off excessively, causing distraction even in heavy traffic. Over a 2 hour drive, the inattentive driving warning would alert approximately every 30 minutes regardless of traffic or driving conditions. The sound, which lasted approximately 1 to 2 seconds, and alert display caused me to momentarily turn my attention to the instrument cluster, rather than the road, while I was traveling at highway speeds in variable traffic. Previous model years allowed you to turn off this function, but this is no longer the case. Hyundai even confesses the inaccuracy of the system within the manual and has sent out notice of ways to lower incidences on different models vehicles.

Check engine light keeps coming on got it looked at , certain parts replaced & it’s still on something to do with the air filter.

Vehicle dashbaord has been facing uv related reactive damages by small line cracks and now it's progressing to larger lines. Similar damages in other manufacturers like Toyota and Lexus are covered by manufacturer as recalls .

1. Sunroof disengaged from car. Yes 2. Glass falling from car. Glass could have landed inside car, killing or injuring driver. Glass could have landed on any car behind the Sonata killing or injuring occupants in that car. 3. Unknown 4. No 5. No.

All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable.
