After an oil change, my car started losing power at the gas and suddenly turned off on me while I was driving and never turned back on! When I tried turning my car back on my engine started smoking
2012 Hyundai Sonata acceleration complaints
Page 2 of 4: complaints 11 to 40 of 84, newest first, as owners wrote them.
After the recent recall repairs, the car started to intermittently getting a message on the dashboard saying ‘Hybrid System Warning - Safely stop and do not drive’ and ‘Check brakes’ and the brake lights came on with a loud chiming beep, the car would stop accelerating and would not go beyond 10 mph, also the breaks would fail to apply correctly and made a loud screeching sound when applied. It used to do have this issue without any warning, while driving or stopped at the light, without any distinguishing pattern. However, it used to go away when the car was restarted multiple times. However now the message is on continuously and doesn’t go away with the restarting the car. After taking to the dealership, they said that the repairs would cost $3000 as the Hydraulic Power Assembly unit has failed. After looking for the issue online, I have found that a lot of the 2011-14 Hyundai Sonata Hybrid have this same issue and seems to be a manufacturing defect. This is a huge life risk for the owners of this car since it can happen while on the freeway and pose a life threatening risk to their life. It is also a huge financial burden for the owners for a manufacturing defect. I would like you to investigate these issues and provide us with a appropriate solution.
The contact owns a 2012 Hyundai Sonata. The contact stated while driving 70 mph, the accelerator pedal was depressed however, the vehicle failed to respond. The vehicle decelerated independently with the Electronic Stability Control warning light illuminated. The contact was able to drive to the residence. The vehicle was not diagnosed or repaired. A dealer was not contacted. Upon investigation, the contact associated the failure with the federal safety agency Campaign Number: 15V759000 (Exterior Lighting) however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 141,000.
Driving in traffic in town and accelerator pedal quit working. Deceleration happened until I went from 40 mph to 2mph. Then able to accelerate back up to 30mph and happened again until I coasted to a stop. Traction control light came on after second incident. Car was in park and still on. Turned car off, took key outside vehicle and exited vehicle. Car locked itself and brake lights came on and stayed on. This is a danger!!! Can cause an accident, driver has no control over vehicle at random times. Traumatic and scared to drive vehicle now.
Brake light switch plunger does not retract as it should when the brake pedal is not being pressed, car looses acceleration and looses power. When driving on cruise control, break will depress and turn cruise off and on in dash.
Vehicle in motion, less than 40 MPH on a city street with a slight incline, less than three miles from home. Vehicle started to operate sluggishly without warning, with lack of power when accelerating. The check engine light started flashing, acceleration severely decreased and was unable to go over 20 MPH (car was placed in limp/engine protection mode). I slowly drove the car home and was able to troubleshoot the issue. Connected on obd2 scanner and immediately received a dtc p1326; indicating the knock sensor detection system placed the car in limp mode due to a detected knock/vibration in the motor. Further research proved service campaign 953 (tsb 19-01-002h-1) was already opened in late 2018 to help resolve the p1326 issue and many 2011-2018 sonatas were recalled to get a software update for the ksds; as an early preventive measure for possible faulty bearings/rods in the motor. I had the vehicle towed to my local hyundai dealership to get the ksds software update after receiving the p1326 dtc. The service tech said my VIN was not part of a recall or campaign and charged me $173 to update the software and clear limp mode. The hyundai tsb clearly states this update is free to the customer and applies to all sonatas from 2011-2018; regardless if the vehicle was not part of the original recall.
I'm concerned about this recall due to the fact that I can tell the difference in my car and I'm just trying to be safer while driving so if I can get any information about this that would be great
Sometimes when I press the gas, the car will basically take an extra second to speed up, and probably 70% of the times that I press the brakes to slow down or come to a stop, itll (also) take an extra second and itll stall/jerk 1 time, then finish slowing down or stopping....its gradually been getting worse as time passes...the engine needs some work definitely! (I'll feel much more safe after this engine recall is fixed!)
I had a very scary incident friday night, 12/18/20 about 8:30pm. I was about to merge onto the 5 fwy north to go home, and as I am coming out of the turn, and accelerating to anticipate the flow of traffic, I see a big rig in my rear view mirror in the distance. Naturally, I step on the gas to punch it, to give myself and the rig plenty of distance as to not collide. My car revved up and decelerates to about 2mph . I panicked and managed to coast the car to the shoulder as far right as I could and the rig barrels down past me. I was afraid to completely stop on the shoulder of the fwy, and the car lasted long enough to coast to the next exit. I am able to continue steering my car close to the shoulder at a crawling pace, and turned on my hazard lights. I had people mad behind me, but I could not speed up. I managed to coast to the nearest exit, come down the ramp, and stop briefly with just enough momentum to steer left onto telegraph in commerce, and my car completely dies in the first lane. This is the second time my car just dies on me while I am driving! First time was three years ago in december 2017 . The car had initially died while making a left turn. However, after turning the car off and waiting a few minutes, I was able to turn the car on and drive no more than 30 MPH to the same downey hyundai. The issue was under full warranty and repaired, but now a second time? Worse yet, this happened while excelerating onto the freeway. I don't want to drive around in a car that has repeated recalls for various issues. I also don't want to worry of my car dying on me a third time. My sonata is currently at downey hyundai and they have started diagnostics and will have a better reading as to what happened. I have lost all confidence in this vehicle and worried for my safety and that of any passengers I may have with me.
Brakes light stay on after ignition turned off. Car de-accelerate while driving on expressway.
After having to have my engine replaced due to my crank shaft getting clogged with metal pieces on the highway and destroying the engine. I've been having issues with the replacement engine feeling like it's stalling out or losing throttle either during a turn or shortly after. It's never popped and error code and only happens now and then.
In july 2019 I noticed that the brake lights came on in the middle of the night, although there is nobody in the car at that time. For the next few days the brake light were tuning on even when I was not pressing the brake pedal. In the same time the electronic stability control started to take over and it refused to accelerate when I pressed the gas pedal. The only way I was able to make it work was to depress the gas pedal and then press it again. I took the car to the mechanic because it was behaving very strange. The mechanic told me that the problem is a rubber stopper that kept the break pedal in place. When it is worn, it behaves as if somebody tried to hit the break. After the problem was resolved I discovered that there is recall 136 the accurately describes my problem for my car model. I contacted hyundai about a possible recall but I got no response.
Break lights won't shut off when the car is off it drains my battery car has a hard time driving at a certain seed constantly jerks while driving and car speeds up when not going fast at times I've taken it to hyundai they refused to look at the problem because they stated they've gone into the car to many times I have children I can not keep driving this car like this is there anyway I can exchange my car for something with the same value car had an engine recall the car started smoking I feel like someone tampered with my car at the dealership I've only had the car for a year in a half I shouldn't be having these issues at all
There is a knock in the in the steering wheel and when I hit a bump its sounds like something is lose the problem is getting worse. It happens when I drive or when im sitting still if you turn the steering wheel it knocks
Car hesitates under acceleration while driving. Does it on road and freeway. Break lights are always going out have to replace every other week possibly have problems with wire harness. Shocks and struts started making noise right before the 60,000 mile mark wears off tire because of it. Car started having similar problems early on when I bought the car at around 12,000 miles for the acceleration. Break light problems around 60,000 miles suspension around the same time. Have had the engine replace twice on this car. And currently in the shop again.
Vehicle stalls/dies while driving. It stalled 2 times but when I pulled over, it would start right away. While trying to make it home, it stalled for a third time and while pulling over it started smoking so bad I thought the vehicle was going to catch on fire. Vehicle had to be towed. There is an engine recall for this vehicle but dealer is giving me the runaround. Very disappointed with how hyundai has handled the incident that almost caused an accident that could off been deadly.
Driving at interstate speeds, will down shift and drastically lose speed while in blue mode. No warning lights of any kind. No apparent issue at lower speeds. Engine does not rev up high because of rev limits. Drops from 6 gear down to 4 gear quickly loosing speed. Leading to impedance of traffic flow. A couple of time this happened when merging on to interstate. Had to ride on side to next exit. I have learned if I go into sport shift mode I do not experience this issue. I have taken to dealership, but unable to repeat issue on test drive. They did a diagnosis and cleared some history codes but it did not help. Again this happens unexpectedly.
Engine failure: I own a 2012 hyundai sonata. On july 2, 2019, I was driving home from work on the highway in the far left lane, driving approximately 60 miles an hour when suddenly the engine stalled and the car would no longer accelerate. It then started making a knocking noise. This was a very scary occurrence especially to happen on the highway. But fortunately, I was able to slowly cross over, safely get off at the nearest exit, and pull over to the side of the road. Several warning indicator lights were flashing on the car (including the engine light) and I detected a slight burning odor (but no fire). I was able to restart the vehicle but it stalled again and eventually was towed to an independent mechanic who diagnosed a complete engine failure. The vehicle wasn't repaired but towed to the closest official hyundai dealership (256 north franklin st, hempstead, ny) for assistance. The following recalls are associated with my vehicle: recall# 17v226000 (engine), and #15v568000 (engine). At the time of occurrence the vehicle had oil in the tank and had approximately 88,000 miles on it which should not have affected the engine at all. I sincerely hope that by reporting this incident, it will assist the hyundai dealership in repairing or replacing the engine in my vehicle as stated in the recall and thereby preventing this from ever happening again. This is a very dangerous incident and wouldn't want to ever subject myself or my family (who also ride in this vehicle) to a terrible incident such as this or worse.
My car's check engine light came on and I took it to the shop for diagnosing. The code p1326 came up and nobody can figure out the problem. My car doesn't accelerate properly and take a minute to shift gears and drive properly. There has been open communication on the issue by other people.
Last night after parking, my break lights remained lit. My father and I both checked either anything inside was depressing the brake pedal, and the emergency break was not engaged. I drove about 20 miles to work the next morning (lights still on). Parked at work, lights stayed on. I was driving on highway and tried to accelerate around 50 MPH. Car braked/decelerated instead of accelerating. I exited highway immediately and pulled into a neighborhood. I am able to pull the lever to change into r/n/d without pressing the brake down (you should have to press break first before switching). I know this was a recall issue for elantras and sonatas at some point, but I don't believe it included my cars year. There have been so many recall things, it seems maybe hyundai just makes faulty products. 2012 hyundai sonata. 78,000 miles. Traction light also illuminated while driving this am, but perhaps unrelated as it was foggy and so maybe slippery?
While driving and pressing the accelerator it acts as if its not getting any gas, so when I remove my foot and repress it, it moves right along. It has happened 2 times in the last 24 hours. Now, I exited the car and went into the house and the brake lights are still on.
While driving at any speed with the gas pedal depressed, the car will suddenly slow down when I hit a pothole or bump in the road. It does the same thing when using cruise control. For example, I'll be driving 50mph and I'll hit a bump in the road and my RPM and speed will drop. If I take my foot off of the gas then re press it, it re engages and accelerates again.
At any speed the engine will return to idle without moving the gas pedal. It will do the same thing when using cruise. Pushing the gas pedal will re-engage the engine. It acts as if you take your foot off the gas. There are no warning lights and everything acts normal (lights, power steering etc). This started in mid march 2019. It is becoming a daily issue. . My wife is scared to drive it. I took it to my hyundai dealer and they could find nothing wrong. It did not do it for them. They said it showed no codes. I keep very good care of my sonata. It has 180,000. My dealer is noller hyundai topeka ks.
Tl* the contact owns a 2012 hyundai sonata. When the accelerator pedal was depressed, the vehicle would not accelerate. In order to get the vehicle to drive, the contact had to release and depress the accelerator pedal quickly. In addition, the traction control warning indicator illuminated. Victorville hyundai (14821 palmadale rd a, victorville, ca 92392) stated that the vehicle was not included in an unknown recall regarding the brakes. The manufacturer was contacted. The vehicle was not diagnosed or repaired. The failure mileage was 180,000.
Had motor replaced from a previous recall, 4days after this fix I noticed a rough idle. Went to numerous shops incld dealership was told by dealership that recall was done and any other repairs would be out of pocket. Problem has progressed from rough idle and engine noise to poor acceleration and mistimed boosts. As in when entering highway car doesnt accelerate very fast very long delay before boost intiates. Once at desired speed when slowing down car boosts without pressure to accelertator!!! Now that winter has arrived, sporadically on cold start car idles even rougher and sounds as if it with shut off. When driving in traffic car idles rough then shuts off!! No power steering! No lights ! No power! This happened whilst car is in drive and in motion! I try to avoid hwys and night time driving when I can as im scared to death of this car. I purchased it used in dec2017 11 days later intial issues began with car loosing power. Now after issue was "fixed" by replacement motor same intermediate lost of power issues again but with the added boosting issue as well now.
Tl* the contact owns a 2012 hyundai sonata. While pulling into a parking space at approximately 10 MPH, the vehicle accelerated independently and crashed into a curb and a handicap sign. Afterwards, the vehicle accelerated rapidly without warning while in reverse. As a result, the contact crashed into a parked vehicle. The air bags did not deploy. A police report was not filed and there were no injuries. Fairfax hyundai (10925 fairfax blvd, fairfax, virginia 22030, (703) 352-0444) was made aware of the crash and requested that a test drive be conducted. The vehicle was taken to a body repair shop to be evaluated for the damages. The manufacturer was not made aware of the crash. The vehicle was not diagnosed. The failure mileage was approximately 57,000.
Takata recall when you press on the gas the car stalls then drives . When you turn on the headlights the back tail light goes out. I took my car to hyundai multiple times to get these and the air bags checked out and still they didn't fix nothing. When I first got the car I had totake it to hyundai bc it smelled like smoke they fixed it but now when u turn on the air the car don't excel the way it does when the heat is one
After driving for a few minutes on highway, my 2012 sonata hybrid will start to jump and buck. It slowly loses power and when it reaches lower speeds (under 40 MPH) as I try to accelerate it will feel like it's trying to catch the next gear but won't. I will continue to lose power so I have to try to leave highway or pull over, which can be dangerous on a high speed road. It has happened three times since august 2018. Just took back to dealership but first two times they said they could not replicate problem while test driving it and all diagnosis indicated the car is fine. I see in some web sites that other users nation-wide have had the very same problem but with no resolution at hand. This is a very concerning safety issue as the last time it happened the car behind me almost run into me as my car lost power and speed rapidly and started to buck/stutter.
When attempting to initiate cruise control on the highway only the on/off button will work, show with the illumination of the cruise light on the dash console. The set and resume buttons will only work approximately 30% of the time and the cancel button never works. When the system is allowing me to set it the only way to disengage it is via the brake.
When the headlights are in use, the car randomly loses power, headlights turn off, entire car just shuts down without warning, then after several seconds, powers back on. The lights, engine, everything turns off. Also, when headlights are in use, cruise control and stability do not work. The vehicle is in motion and this has happened on highways and city streets. I have taken my vehicle to the two nearest dealers and they refused to fix the vehicle. Generally, this happens when braking, using turn signals, changing to hi beam/low beam, but has also happened for no reason at all.
