My car has been driving in limp mode for almost two years. I have taken it to the dealership over 8 times for the same problem while it was still under warranty. The replaced the knock senser twice and it passes the bearings test. My check engine light blinks and it hesistates while driving. I only had the car for one month since this started and everyone is giving me the run araound and not fixing the problem. Now my warranty is expiring because I have over 100,000 miles on it but nothing is fixed.

My car engine just stopped working on me. My check engine light came on and then my oil light and the car wouldn't turn on. Car was stationary.

While driving down a residential street, I received a notification that my car essentially was no longer charger and would cut off. I was prompted to pull over and stop the car. I cut the car off. When trying to restart, it would not cut back on. After about 20 minutes, it did restart but the check engine light was on. I ahve not driven it since. There is an outstanding recall on this car that has yet to be remedied and thus far Hyundai has not provided any solutions.

I was driving on the highway and all of a sudden the engine lost power and my speed dropped to 20 mph. I could not go any faster. Other cars were honking at me and almost hit me as I try to get to the shoulder of the road. The check engine light came on and I had the car towed to Hyundai of duluth GA. They scanned it and said it was code p1326 knock sensor detection. There is a NHTSA service campaign for this- https://static. Nhtsa. Gov/odi/tsbs/2019/mc-10154682-9999. Pdf (TSB #19-01-006h. The problem is Hyundai dealer does not have a fix because they said corporate diagnostic equipment is not working. They have had my car for 5 days now. They do not have any loaner vehicle while my car is inoperable. My complaint is they should have loan cars or pay for rental cars for customers with this problem. I demand they fix my car soon or give me a rental car to drive to work.

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.

Motor locked up . Was driving check engine light came on then 10 mins later car stop lost power.

I was driving to work when a warning showed up on my vehicle. The warning message said: check hybrid system, turn off engine. The check engine light came on right away and another like shaped in a triangle form with hev written inside of it came on as well. I pulled aside and turn off the engine and call Hyundai. I was told they do not have a remedy for the engine recall yet, and they asked me for $9444 to fix the problem it's not their problem even though they have the recall on the engine.

I was driving on a city street when the check engine light started flashing. The car started knocking not running well. When I took it to the repair shop they stated I would have to replace the engine because it had seized. The repair shop also stated they had replaced 20 of the same model within the past 12 months. We are currently working with the extended warranty company to see if they will cover it. We have maintained the engine with regular oil changes.

2016 Hyundai Sonata hybrid ignition issue the engine is rattling while idling and under acceleration and the check engine light is coming on. Believe it is an issue with either spark plugs or ignition coil. Service dept said both components looked free of damage upon inspection.

During long distance driving once the vehicle is stopped for gas the hev warning light comes on. The car will not re-start for 15 -30 minutes. Once restarted the check engine light comes on. This has happend 3 times. The first two the thought was a long distance drive in the heat of summer. This last time it was fall/winter so the hypothsis of summer heat was thrown out the window. The most recent time the gas mileage went down drastically and the voltage for the electric system was acting erratically. The check engine light was on for 2 days but the car was only driven to the dealer. The dealer quickly found the problem and repaired under warranty "open recall". The car has not been driven any long distances since. The diagnosis was "main relay/power relay/cable (20-01-003h) caused by t4m. Power relay module melted at relay" installed 37583-a8000-qqh: relay-high voltage main, 37514-g0000-qqh: relay assy-power, replaced power relay assy module per campaign "warranty" hope this information helps others. . . . Hope this is truly the fix as it is an "open recall" that should be a recall". Glad this did not cause a fire.

Back in may of 2020 my car out of the blew lost power and my check engine light started flashing. I immediately pulled over, I got my car towed to my closet dealership and they stated it was the computer system. 4 months later, three days after my oil change my car completely shuts off and my engine started making this crazy noise. Dealerships says my enigne is blown, I really dont understand how that happened. They want 6,000 to fix my engine and I cannot afford that especially now. Theres something really wrong with these engines and its not safe nor fair to what yall are doing to people. I was even told by the dealership the Sonatas have really bad engines.

Check engine lights comes on and oil light. So im prompted to get oil change. Mechanic says he reset some codes and the engine locked up. Mechanic took my running vehicle from the shop to check how it was driving and the car stalled in motion.

Check engine light flashing, vehicle will not go over 20 miles per hour and jumps. Started suddenly when in motion on road.

The oil plug fell out and seized the engine. I bought the car and drove it lightly for 2 days through city streets and highways. Right before the engine seized. The check hybrid systems light came on, followed by the oil light, then the check engine light (within the span of around 45 seconds). After the lights the car became unresponsive to the gas pedal and slowed to a halt. After getting it towed to a Hyundai dealership the next day, they called and said that te oil plug is missing and it caused the whole engine to seize and need a complete replacement. After researching I've found many owners of 2017 Hyundai sonota hybrids to have had similar issues with the plug falling out. I believe it should be looked into getting recalled.

Sometimes while driving the car jolts back and then the gear indicator disappears on the gear shift and the letter disappears from the spot beneath the speedometer. When this happens and let off the brake the car stays still and when I attempt to accelerate the car struggles to shift gears. Also if this occurs repeatedly the check engine light turns on. I've told multiple dealerships and carmax about this issue but every diagnostic test save for one never reports the problem and it seriously impedes my mobility.

My car consumes a lot of oil and gas. . Check engine light will not stay off. My gas cap will not click at all for some reason. I believe this car is malfunctioning and has ruined my engine. My car started rattling really loud while accelerating on a busy road, I was scared.

As I was driving on the freeway my car which was on cruise control. The car went from 60-50-40-30 within 30 seconds while it still said cruise control was on and the gas and brakes didnt work.

Yesterday I was driving and out of nowhere my car shut off and all the lights came on but the crazy part is. The car still was moving and didn't stop until I stopped and pulled over. (so weird) I turned the car off and started it back up. It came on with no problems but no check engine light is on and it's flashing. I never see a flashing check engine light. Back to the story I'm driving but I can only go a certain speed or the car would stall and jerk like it's about to cut off. I did not repeat did not stop until I made it home lol. The whole time driving it kept stalling. In order for me to get home I had to jump on the highway but I took back roads just because I was scared the car would stop on the highway. O and don't let me stop at a red light hunni, it's taking its time to get up some speed. This the second or third time it did that but this time the check engine light came on. Is this under a recall? if not it definitely should be because that was so damn scary driving. That was the longest 23 mins ever lol.

While driving on the highway, apx 70mph, occasionally my 2014 Sonata GLS will completely die. This has happened at least 10 times not in the last two months, always when the car is in motion usually at highway speeds. The dash lights all go black, radio cuts off, and engine dies, for apx 2-3 seconds, and then usually turns itself back on like it never died. Occasionally though the car will not turn itself back on. When it dies, the steering also becomes very stiff and the brakes are extremely hard to use. My car has only 112xxx miles and has always been serviced regularly. There has never been any check engine light on or any codes stored when checked. I've contacted Hyundai service center multiple times. Each time they tell me that they can't help me, there are no recalls and I should �check my battery connections�. I have, they are all fine. I'm very concerned for the safety of myself and my three children. Three mechanics now have checked out the car and they can't seem to find any problems.

Vehicle rough idled & eventually shuddered to a stop. This happened four times while in gear and idling at appx 1000-1500 miles. Between 1500-2000 miles, vehicle shut down while driving appx 60mph on a county road. At appx 2700 miles, mpgs drastically impacted when vehicle suddenly stopped shifting gears properly while in motion at appx 70mph on the highway. Check engine light appeared with message regarding ecs issues. Vehicle still drives, it just seems to struggle with efficiency and shifting correctly.

After a period of driving, which is random at best, the check engine light will appear and the vehicle will start to shudder and lose its ability to accelerate. This happens when the vehicle is in motion and happens both on the freeway at high speeds, as well as on city streets in low speeds. The only way to get this to stop is try and get to a safe space of the road and turn off the vehicle. It is very scary and dangerous especially in southern California freeway traffic and in mountain passes as you lose the ability to maintain speed in the middle of traffic. This could very easily cause an accident. This has happened to me on 7 different occasions over the past 2 months at random times.

Within the last four months, the car has shut off while stopped three times. The first time, I was stopped at a red light when everything just shut off on me. Took the car to firestone later that week to get it looked at and they thought it was something with the battery so they replaced it. The second time happened earlier this week. Again, I was stopped further back from a red light in traffic when the car shut off. I was in the left lane in a 55 mph speed zone and the car had shut off right has traffic ahead of me began to clear and I was about to move. Both times, the car turned back on after placing the car in neutral and turning the key. Neither time did the check engine light come on before or after. The third time was yesterday. I was parked in a parking lot. A few seconds after I had turned on the ac, the car turned off.

The engine in this particular model is Hyundai's 2. 4l gdi (theta ii). The engine seized without warning even though it had the software update that detects engine wear and prevents engine failure while driving. Hyundai did well and replaced the engine under warranty and provided me a rental vehicle. 8,000 miles later with the same vehicle now the check engine light is flashing and acceleration is dramatically reduced. I was able to take some backroads with little traffic to a local Hyundai dealership and am waiting for diagnosis again. This started on a very busy local highway.

I never had a check engine light on my vehicle but while I was driving in the middle of the road the vehicle engine shut off. I recently got my oil changed. .

I was driving my car at about 45mph on my way to work on a highway road and out of no where it jerked and the check engine light started flashing. Car would not accelerate above 2,000 rpms. When the car jerked, it was so sudden it injured my lower back. My back has been very sore since this incident. I then took to dealer and they said it was a known issue and Hyundai had not recalled my specific car. Dealer was able to replicate the issue. The cleared the check engine light and sent me on my way. One mile down the road exact same thing happened. Car is currently at their shop with no eta of repair.
