Vehicle Speed Control Problems of Hyundai Sonata - part 2

Vehicle began to lose power while on highway. The loss of power occurred for a few seconds, then came back. Shortly after, the rpm began changing uncontrollably. Tried shifting to manual control using paddle shifters and was able to maintain steady rpm until vehicle software switched back to automatic and rpm swung crazy again. Endangered other vehicles on road due to loss of power and fluctuations of transmission. Once parked, vehicle did not change to neutral, drive, reverse. Both manufacturer and insurance are/have reviewed vehicle and are working on a fix. No warning lights. Only indication was minor loss of power prior to incident. Loss of power was not considerable nor for a prolonged period of time.

Check engine light start flickering while I was driving down the road my vehicle went into limp mode and I lost all power. I checked my oil for metallic shavings or a creamy look but everything was cleaned. I got a code 1326 for knock sensor. I replaced and changed the oil and oil filter and reset the code. I started it up and it sounded good then I drove to see if it was fixed got on the highway and my engine went back into limp mode I lost power again. And my engine started flickering I stop the car and tried to turn it back on but my engine locked up. Could I possibly get help with getting a new engine. The car only has 127,052 miles. I heard there was a bunch of problems with rod bearing wear and etc with 2017 Hyundai Sonata se.

The Hyundai Sonata was brought to a stop in a parking lot. When the driver went to put it in park, the vehicle accelerated across the parking lot and smashed into a solid wall. The driver broke her right ankle from standing on the brake pedal. The brakes were ineffective at stopping the vehicle. The collision avoidance system failed to activate or warn of the impending collision. The driver and passenger were severely injured and the car is considered a total loss. There were numerous other injuries sustained. No one outside of the vehicle was injured.

I see that the recall notice was issued in September of 2023 but I have to say that for no recall remedy to be available yet is disheartening. I drive my car every day and it is the only car I have, because of that I risk my life everyday. My car loses power because of this recall daily and it ranges from 3-6 times a day. I lose power on the highway, the main roads and back roads, it does not matter the speed or time of day. I would like them to push out a fix now. Eventually I will end up in an accident because sadly I cannot afford to get into a new car or a used car.

While driving at about 45mph a warning flashed on my dash. I couldn't read it before it disappeared, but it was something about front collision. , contact dealer. The car immediately lost all power. Everything was still running, but I had no acceleration. I had to back down a busy road into a vacant lot. I had just come off of the highway when this happened, if I had still been driving on the highway, I would have been hit by a car from behind, since there was no warning at all. The car was towed to a Hyundai dealership. After a diagnosis, it was said to be the throttle body. I had to wait for the repair because the part was on back order. I was told that there was another car there waiting on the same part. I am afraid to drive the car now, even though the repair was made. I feel this is a safety hazard, and that someone could be injured or killed because of this issue with the car.

I have a 2016 Hyundai Sonata that has had repeated engine issues including stalling overheating and shutting off. The car engine also caught on fire on 11/30/2023 and was reported to Hyundai comsumer affairs where a case was opened. The car was in the dealership for repair until 1/4/2024 I have a warranty that the dealership or Hyundai did not honor for the engine, power train. The services that were repaired was a replacement of a engine piece which is continuously variable valve timing) system which controls the controls the open & close timing of intake valve to improve engine performance. On approximately 1/7/2024 3 days after picking the car up which I had to incur the cost of the repair as Hyundai did not honor my warranty the engine as well as oil light came on the car repair included transmission oil flush and engine oil replacement per the dealership. I contacted the service manager mr espinoza who was overseeing my case and informed him of the continued issues he asked me to drive the vehicle in to be looked it. As we have had inclement weather in my area I was unable to take the vehicle in. On 1/26/24 I attempted to drive the car to the services department at pohanka Hyundai only for the engine to make a roaring noise and stall also there was no engine oil in the car wherefore it should’ve been. I contacted the dealership and told they were busy and to bring it next week. I am requesting Hyundai to buyback the car.

Intake camshaft cvvt cover and sensor intake camshaft cvvt oil plug plug exhaust manifold I am up to date on all me oil changes and everytime I get and oil change the oil goes so fast! this has actually been happening ever since I got the vehicle. My acceleration has been decreasing when I get an oil change.

On 1/3/2024 the car was at a low speed - once when parking and once stopping at an intersection - when it suddenly accelerated without the accelerator being touched. The only way that the car stopped was that I was able to shift it into neutral. According to online forums, this has been a known issue with several kia and Hyundai models.

This is a 'stop lamp switch' issue. The car will randomly turn on the abs light causing the abs system to engage and not allow you to use the accelerator pedal. This is very dangerous as if you are about to merge on or off a highway the car does not allow you to correctly control your speed. This issue happens more prevalently at night time when the full beam headlights (auto or manually turn on when dark out), which is very concerning. This issue has been going on for a year now and no mechanics at Hyundai can fix or diagnose. It happened again to me this morning and came very close to causing an accident as I could not engage the accelerator pedal on a turn. Please, in the interest of safety and saving lives fix this dangerous defective part issue.

I have had three occasions where the dashboard lights would flash and the car would lose all power. The first occasion occurred on December 29th at around 12:20 pm at a crowded intersection. The dashboard lights lit up and all of a sudden the car had no power at all. I managed to get it through the intersection and pull it off to the side of the road. To start it up I have to turn off the car by putting it in park and start it up again. This is stressful and terrifying to think about if this had happened on the freeway. Additionally, I took the car to get serviced and was charged a $1,800 bill to fix it in January. This repair took two weeks to complete. The car has since turned off two additional times on February 15th going down a hill at 40 mph and March 26th on a mountain road going 60 mph. I am very concerned this will happen on the highway and I will get into a serious accident or worse. To make matters more difficult, I have taken the car back to the Hyundai dealer again to have it looked at in April and will most likely be without the car for at least another week. I bought the car brand new and the check engine light has gone off four times since then.

The vehicle has twice been disabled while driving due to “lost communication with hybrid module powertrain control module. ” this breakdown is a significant safety hazard as the car loses power and coasts to a stop without any warning. The second time was on a 65 mph highway. Neither time has had any warning before the malfunction lights appeared. The first time occurred on 10/7, and the vehicle was towed to the dealership. Nothing was done besides clearing the trouble codes and test driving with the car, which returned at the end of October—the second time the breakdown occurred about a month later on 12/3. This second time, I removed the code myself on the roadside so as not to be in more danger, and I am currently awaiting an update from the dealership’s service department on their next steps after initially being told to just have it towed in again. Losing power without notice is incredibly concerning. I want to report this safety issue and determine my next steps to resolve it, as this has dramatically impacted my trust in the vehicle and its safety.

The contact owned a 2016 Hyundai Sonata. The contact stated that while her son was driving at approximately 45 mph, the check engine warning lights illuminated. The vehicle began to shake, lost power, and failed to accelerate. The driver pulled over and noticed smoke, and the vehicle caught fire. The fire department was on the scene and extinguished the fire. It was unknown if a police report was foiled. There were no reported injuries. The air bag did not deploy. The vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 62,000. The insurance company deemed the vehicle a total loss. The contact mentioned that in 2021, the motor may have been replaced.

I was driving and the car slowed down in mid street on a busy road and started to stop then it sped up very fast then it slowed down again and sped up very fast again I had to drive all the way home 15 minutes without barley pressing the gas I went to autozone to get a code reader to see if what had happened would pop up on it and they said nothing but that incident was very strange because it has never happened before and it happened out of nowhere on a very busy street.

Hev warning turn off engine sign while driving on the interstate my car lost power and the car behind me had to suddenly move over this is very unsafe while driving down the interstate.

My car had engine seized while driving on the road with no warning light prior nor other mechanical issues. When the engine seized, all mechanical powers are have lost power including brakes and power steering in which have almost caused a near accident at an early morning rushed hours. The vehicle's odometer reading at 120,836 and was up to date on all normal tune up performances. Other issues that have arise after purchasing the car are: warning light came on for airbag, real loud clunking sound on roof when hitting a bump on the road and engine will not start because of fuel line system issues. Cruise control had also stopped working after a year of purchased.

What component or system failed or malfunctioned, and is it available for inspection upon request? the car continues to have inconsistent acceleration, hesitation, and sometimes lurches forward. On two occasions, the car felt like it was just going to turn off while driving. I was driving about 75 mph on i295 and driving about 15 mph on a residential road during the second occurrence. How was your safety or the safety of others put at risk? I feel as though I am not in complete control of the acceleration but am mostly concerned with the car stopping on it's own. I am very scared I'm going to be hit by the car(s) behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have an appointment in October for the car to be evaluated by a dealer. I hope it doesn't happen again before then. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? the only time a warning lamp came on was during the second episode when the car felt like it was going to turn off; the engine light came on and immediately off.

The brake lights stay on all the time, thus preventing vehicles behind mine from knowing if I'm actually stopping. Hence, they may stop without reason, and endanger drivers behind them. The manufacturer has likely known of this being an issue in Sonatas from, at least, 2007 through 2013 models. The manufacturer is putting the task of solving the problem (if that's even possible), upon a dealer. And, my trip to that (nearest) dealership (75 miles away) creates its own danger. The danger is added to by a pre-existing unsolved issue of the horn not functioning. As per the brake light issue, I've been to the dealership about it twice, and they weren't even aware that the brake light switch they think attaches to my car doesn't. So, I wonder if the manufacturer tried to address the issue in the middle of the 2011 model year, installed a different model switch and wiring on more newly built cars in that model year, and decided to ignore the owners of vehicles sold earlier in that model year. As for an additional related issue, unless I disconnect my battery when not in the car. The lights stay on and run down the battery. That can contribute to its own safety issue.

Malfunction cause unanticipated acceleration in sport driving mode.

This incident singled happen in a 20 or so miles on my way home commute, no freeway drive. I was driving pulling out of a parking street when I notice the vehicle tendency to pull me forward, even though I was preparing to stop. It continue to have this issue at a stop sign and traffic light. At first it was mild pull as if you are being towed. Sporadic pushing forward, but when I turned to the left I notice that the engine pick up speed on its own and the issue was exacerbated on turns to left and right. The issue continue to the point I stayed at a safety distance from other cars and the pull began to be more aggressive. I was driving slow at that point. With hazards lights on. On arrival to my home driveway and upon putting the car on park the engine rmp jump so high that scared me! the car sounded as if it would take off by its self. I had the foot on my brake and did not pump at that point. I took car to the dealership the next day and it continue to pull at sporadic times I drove slow and cautiously . Noticing that the pull got worse driving on a straight street versus the day before only on turns having more aggressive forward acceleration pulls. The dealer has check the car and has not been able to detect the problem with computer codes and apparently have not been able to reproduce the issue after driving the car. The mechanic, told me to take pictures of engine light if when I drive it has issues, and the light comes up. But not other solution was given.

The contacts daughter owns a 2015 Hyundai Sonata. The contact stated that while the vehicle was idled the vehicle hesitated.

The contact’s daughter was able to gain control of the vehicle and depressed the brake pedal to stop the vehicle. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic where the vehicle remained, and the diagnoses had not yet been determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 95,000.

My concern is a potential unintended acceleration forward as. I was. Parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured. I can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. Vehicle currently being worked on at collision center where insurence appraisor gave go ahead with estimate to repair damages.

While I was driving the vehicle late last year (2022) I pulled out of the parking lot of my office and my vehicle did not accelerate even though I was pressing the gas pedal. I pulled over, turned off the car, restarted the car, and everything was normal again. This morning (8/15/23) as my wife was driving my son to school, the car did the same thing and the vehicle did not accelerate even though the gas pedal was pressed and the rpm's were registering but there was no drive power. She had to pull over and restart the car as well.

Found me driving on I 75 and I put the cruise control at 70 miles, instead of maintaining the speed at 70miles the vehicle accelerated to more than 90 miles per hour I had to quickly put my foot on the brake otherwise I could have an accident with the vehicle from the front, after all this happened, I felt the car was losing speed, I tried to accelerate but it did not go over 60 miles per hour. I took it to the mechanic and they did not detect anything in the vehicle's computer. This vehicle also turns off at times when you are driving and it turns off it also spend too much oil motor , I started looking for information on this model of car and I see that there are more than 550 people who have the same problem as me, this is an unsafe vehicle for the road.

The engine and yes it is. Because my car turned off in the middle of the loop on the highway when there was a lot of traffic and we could have gotten hit. No it has not been. No it has not been. We were driving on the highway then the engine started sputtering and it wouldn’t go faster then 40 when I tried pulling off to the side that’s when the engine ,battery ,and oil light turned on and after that the car just shut off and wouldn’t want to turn back on.

Purchased a new Hyundai 2023 Sonata from mcgovern Hyundai rt 2 may 22, 2023. After two weeks of driving the vehicle, I noticed it hesitates when I push down on the gas pedal. I had planned to have the dealership take a look but have a very busy schedule, the issue continued each time I drove the car to the point it was hesitating, basically pausing as I cross intersections. On the 26th of July I was driving on the highway, as I started to experience issues when stepping on the gas. Entering a tunnel in boston, I pushed down on the gas pedal and noticed the car was decelerating, I was losing speed, in a panic in the center lane of the tunnel, I was able to get the car over to the far right. The car was shaking aggressively then finally just gave out and I called 911. They towed the vehicle to the police headquarters, I called Hyundai for assistance. Had some hiccups but two days later they were able to service the vehicle, supposedly found a faulty fuel injector. They changed out the 1 faulty injector test drive and said the problem was fixed. I picked up my car on July 28th 2023. There is something still wrong with the car, it still has some hesitation and now misfires. Have not heard from Hyundai, I was assigned a case manager and told someone would follow up, no one has reached out. So lucky my children were not in the car and that I'm safe. I could have been killed, others could have been hurt/killed. This should not happen to brand new cars.

I am writing to bring to your attention a critical issue affecting my 2016 Hyundai Sonata 4 door sedan, that warrants investigation and public awareness. Hyundai cars are currently plagued by engine oil consumption problems that ultimately lead to engine failure, due to there being no warning lamps, messages, or other symptoms of the problem prior to the failure. This is a concerning issue that remains largely unknown to most customers. When these issues arise, car owners such as myself, are often left with uncooperative dealerships that either deny the problem or offer minimal assistance. Even Hyundai corporate and extended warranties fail to provide adequate support, frequently citing owner negligence as a reason for denial. This occurs despite the fact that engine sludge buildup is inevitable, even with consistent car maintenance. Furthermore, I am forced to endure long waiting times for my 2016 Hyundai Sonata 4 door sedan, that has been inspected and, then denied for an engine replacement, and face additional months of delay for them to explain why. The situation is exacerbated by the lack of loaner vehicles and no assurance of rental reimbursement. This leaves countless individuals burdened with repair payments for stranded vehicles. My personal experience has been with ourisman Hyundai, and many others have voiced similar grievances. Numerous complaints have been filed with the better business bureau (bbb) and the national highway traffic safety administration (nhsta), yet little action has been taken to aid the thousands of people who are experiencing the same problems to rectify this issue. It is imperative that attention is drawn to this matter as Hyundai's approach to selling cars with hidden engine issues puts customers at safety risk and places them in dire and deadly harm. I implore all news media outlets to conduct an investigation into these concerns and help shed light on a situation that demands immediate attention.

This vehicle had a complete engine failure. Since it is a hybrid, when the engine shut down, the vehicle lost all power. The driver had no control over steering or brakes. The vehicle crashed through three trees and into a house. Hyundai motors of America and NHTSA are aware of the issues with this vehicle's engine, however, this engine was already replaced. The problem was that the "limp mode" did not enact in this specific car. I brought this to Hyundai's attention at least 20 times and expressed my concern about the threat this vehicle posed to me and anyone else on the road, yet they continued to ignore me or attempt to rectify the issue. This vehicle was part of the class action lawsuit. I was told, after the seventh time the vehicle broke down (fourth time after engine replacement) that Hyundai would buy back the vehicle. That never happened. The vehicle shut down without "limp/safe mode", with an entire loss of power eight times and was brought into the dealership. Hyundai refused to help me. I knew it would end in disaster, and it did. I'm sure my vehicle is not the only one that does not have a safe mode taking effect when the power shuts off and there is no steering or brakes at 70 mph. I am using the date for the last time the vehicle shut off and the driver lost control and hit a house. However, there are eight other times this happened. I have more information and documentation if needed. I'm attaching my first claim, documents collected after that claim, the accident report (did not have photos attached, the photos are from the scene when I went there the next day), and all email conversations with Hyundai since the first engine failure. My big concern here is that even though Hyundai did try to repair the recall issues, they ignored everything else. I told them over and over that the limp mode did not work. This made it morally impossible for me to sell, even if I wanted to. They refused to help. I worry there may be others out there with this issue.

My right brake light has melted my housing due to the bulb getting too hot and my cruise control suddenly stopped working one day the light comes on but when I go to hit the set button it doesn't set or activate.

My 2018 Sonata has been stalling out while I’m driving more so when I accelerate. I have a baby that I’m scared to drive with in the car because it does it randomly. It has been happening more & more everyday. I got new parts/starter etc. No codes on dash. Have an appointment next week with Hyundai to take a look.

Starting in July 2023 I have noticed that the oil consumption for my car is racing through the engine. I barely make it 1000 miles before the oil is completely gone. After 2 local oil changes - I decided to take it to the Hyundai dealer where I purchased the car. This was in October - I have brought my car in 4 times for 1000 mile oil consumption tests. I had to add an additional visit due to the fact that Hyundai changed the testing standards. Now I have to bring it again today - Hyundai has not told me what the next step is other than I have to leave the car there all day - after they speak to tech support they will determine next steps. Most likely a combustion cleaning. Then I have to start the 1000 mile consumption tests again. I live 35 mins from the dealer - I have had to hire someone to take me there to leave car - and I then have to take mass transit to work. There are never any loaners because they are booked months in advance. I have had to rent numerous cars for long distance travel due to the mileage meter of 1000 miles on my car - I am not allowed to go over - if I do have to start all over again. That happened to me the first time. My car is crap at this point - I am not able to use it as I should be able to and Hyundai is giving us the run around. I have been contacted about trading it in and getting a new Hyundai - what a scam. I am not the only person - there are so many of us - follow the chats on facebook and reddit - nobody is helping us. The staff said if your engine seizes - that would be great. People are seizing on highways - that is very scary to me. Why is this not recalled yet?.

Starting 6 months ago air bag light is on constantly. Horn stopped working, speed control doesn't work. The whole steering wheel and buttons with horn doesn't work.

Car has been knocking for a couple of months now, check engine started flashing and it lost acceleration. Towed to shop and code for knock sensor was reading bad. Shop replaced knock sensor, I picked car up and drove away and it happened again. Engine light flashing and lost acceleration, took back to shop and the next day which would be today they said take to the dealer cause it's still reading for knock sensor. My 2013 Hyundai Sonata 2. 0 is now at the dealership in line with the rest of the seized engines. So I have spent $800 ($613 for shop and $200 rental car) and my car is still not drivable. Now I'm back in a rental at$300 a week until Hyundai diagnose, test, and approve the process of fixing the issue with my 2013 Hyundai Sonata 2. 0, it has a life time warranty! this will be the second 2013 Hyundai Sonata I have owned with the engine seizing up! back in Nov. 2021 I went thru this very same thing!.

On 5/30/23 while in traffic I pressed the brake to slow down and the car kept moving forward. I pressed the brake all the way down and I was still unable to stop the car from accelerating. I rear-ended the vehicle in front of me. My car is currently being inspected by a mechanic that my insurance company recommended.
