general problems of the 2016 Hyundai Sonata - part 2

I’ve had this vehicle for exactly 6 months. First incident where I thought the company I bought it from lied to me because they said they topped off my oil. In reality it guzzles oil excessively, I paid $600 to get it cleaned out & add oil. 2nd incident my car shut off at a mcdonald’s drive through, no indication of warning of shutting off until 30 seconds before all error codes on dash. 3rd incident as of 02/07/23 car completely out of oil when I had an oil change a month & a half ago. Had someone come & bring me oil & it seemed to get me a mile away to school, did my school stuff & then tried to get home (30 miles away). When trying to get home my car wouldn’t exceed 60mph and when I got to 62mph it was decreasing speed. After a few moments after noticing that, all error codes on dash came on and I thankfully was able to pull over on the freeway without being hit by anyone. My car completely shut down, called a tow truck, while I waited 3 hours for assistance. I was then notified(by the first shop I took it to) the next day that my motor is bad & I’m lucky that I was able to pull off to the side of the road when I did. A week prior to the 3rd incident random chunks of painting ripped off my vehicle(on the top of my trunk, above the passenger door & on the back side of the passenger door). I had my vehicle towed a second time to the Hyundai dealership themselves and the towing company asked the color of vehicle/make and model and instantly said OH is it your motor? I was weirded out because I was wondering how he knew. He mentioned to me that he has towed 25 Hyundais in the last 9 months. I said well you’re on a role, you can now make it 26. I was also never notified of any recalls on this vehicle until 2 days after the 3rd incident I did my own research and called Hyundai dealership myself & that’s when I was made aware of a recall. Insurance also states that this isn’t something I can claim? & I’m currently waiting to hear back from the dealership themselves.

My car idles very rough at times, and sometimes when idling, it dies out. At times it is difficult to even start as if it's not getting the electrical signal to the engine. Hyundai replaced the fuel pump, but that did not fix the problem, but cost $1,200. No warning messages. Two other automotive companies also did a diagnostic tests, but couldn't find the problem as it seems it has to be tested when it is acting up. It died on me far from home a week ago, but eventually restarted. I'm afraid to drive it especially at night as it died when idling at a light and almost didn't restart.

While driving the hybrid system warning light comes on and says to check hybrid system, vehicle goes into limp mode will not accelerate over 25 mph and codes need to be cleared before vehicle van be driven. This has caused me to almost have several accidents. The vehicle slows down and gives no warning prior to this occurring. It has started happening more frequently vehicle currently has 85k miles.

The vehicle is able to be started without a key by using a usb cable. This makes the vehicle extremely vulnerable to theft. Because of this issue vehicles incur other damages due to theft such as broken windows and possibly bodily injury due to theft. They are able to remove the steering column cover, unplug the ignition switch and using a usb cable as an object to turn the ignition. Because the switch appears to be plug and play it makes it easy to steal cause Hyundai car owners unnecessary dollars for repairs. Https://youtu. Be/fbtrlyql_nw this is the link showing what they do. It’s not just kia vehicles. My vehicle was stolen the same way.

While driving on the highway at speed, I received a red check hybrid system error, and immediately lost all acceleration, putting myself and all occupants at risk on a busy interstate highway, as we tried to find a safe way to quickly change lanes and coast to a stop in a safe location. The cause is under diagnosis by a Hyundai service center. This was a sudden failure and there had been no previous warning alerting us to substandard system condition.

While driving the car getting error message on dashboard "check hybrid system turn off engine", the gas engine turn off and switch to continue on electric till able to pull on the side of the road. Turn off engine, wait a min. Start car again and working fine. This issue appears randomly many times in the last two years while driving. Car was at dealer shop multiple times with no repair, was told we don't see active error message or they can't re-create the error. However scan show p261f error. Open ticket with Hyundai #21018148 while car at the dealers for weeks at the time. Each time told check engine got back on but not the message they are looking for.

My vehicle is a hybrid and the check hybrid system light has lit up while I'm driving and you have to pull over and turn off your car when that happens. The car will slow down and come to a complete stop regardless. It's scary when you are driving on the freeway. I've had this happen to me several times and my car has been worked on four times now by the Hyundai service department in amarillo and lubbock TX. I purchased extended warranty and it's about to expire at 100,000 miles. I currently have around 82,000 miles on my car. I contacted the Hyundai corporate office and have a case number. I'm very disappointed the way the Hyundai corporate office and the service department has handled my situation. I even lost my job because I had no transportation for two months. I just paid off my car yesterday and I can't even drive my car.

Electronic power steering (eps) failure.

My vehicle lost power exiting the freeway. I went from 70 miles an hour to 10 miles per hour in a matter of seconds. The check hybrid system, turn off engine hev ! triangle showed up on the dash, then the car slowed to a halt. I had to get my vehicle towed home, then towed to the dealer the next day. The problem with this is, for the past year, the check hybrid system hev light would come on. I took it to the world car Hyundai north dealership in live oak, texas and a few months later, it's doing the same thing. My vehicle was in the shop at world car Hyundai from March 24, 2022 until 9/9/2022. I drove my vehicle one week, went out of the country for 2 weeks and upon return, coming from the airport almost home, the car does the same thing. You would think after having my vehicle for 6 months, the problem would be fixed. I started bringing my car in for this problem September of 2021. I was told, I needed an oil change, a new battery, ne plugs, codes checked, etc. None of this seemed to fix my vehicle, because a few weeks later, the car would slow to an almost stop and I would have it towed to the dealership again. There has been several mechanics working on my vehicle and they've all said something differently. My vehicle was never written up for the correct problem until recently, when the manager was able to drive my vehicle and it stopped on him. I don't feel safe driving this vehicle anymore. I have taken this car to the dealer ship for the same problem, actually once in 2018 and every other month since 2021. I've been inconvenienced, , put on hold, far to long, I need a new vehicle and I need a loaner car, while my they're trying to figure out what to do. I've been told I needed a new engine twice, but all of a sudden, it passes the engine test and there is something else that the dealership is trying to do to fix the problem. Well, since I've been taking my car back and forth to the dealership, it is now out of warranty. The car remains unsafe to drive .

Had previous issue with hev warning light and took to dealer. But while driving down the road last night, the hev light on the dash comes on and beeps, the car sputters then the brakes slam on and the car immediately shut off in the travel lane. Turn car back on put into drive and same thing happens. Vehicle was towed to dealer.

In may 2022 after driving approximately 2. 5 hours, when I turned off the vehicle and tried to restart, the hybrid symbol "check hybrid system", after waiting approximately 15 minutes to restart and it started. During this trip this happened several more times. I brought it in to a auto zone and he could not diagnose because the light was not appearing. The check engine light also was on but just disappeared. Once I returned from my trip, I brought the vehicle into a Hyundai dealership for diagnosis, however, they said since the lights nor the check engine lights were on, they could not diagnosis. In August 2022 I went on another long distance trip, and the same thing happened, after driving for approximately 2. 5 hours and stopping, the vehicle would not restart and the same warning light displayed, "check hybrid system". Again, I waited 15 minutes and the vehicle started, the check engine light remained on for a while and then disappeared. Again, this happened several more times after driving for more than 2. 5 hours.

The vehicle is highly susceptible to theft. There are multiple articles and videos on how my vehicle and many others made Hyundai and kia can be stolen in minutes with just a usb drive. This needs to be investigated and fixed immediately.

The car requires a quart of oil every 1 to two weeks. Brought it to multiple dealerships and was never given a reason why. Car was making knocking noises anytime driven at 45 or below and sometimes higher. We believe it had to be about the recall Hyundai has advised us about multiple times. We brought it to them on Friday July 22nd. They updated the hybrid system and we left. Driving the car to work July 27th and the car went into “limp” mode and stated that there was a issue with the hybrid engine and to shut the car off immediately. I was able to pull the car off the road and turn it off. The engine light constantly blinked when the error happened. When I shut the car off and turned it back on, it the same hybrid error shows up on the screen again. We had to have it towed to the same dealership we went to the previous day. They have to diagnose the issue but it might take weeks because they have one hybrid tech.

Ive bought this car used at 30k miles currently at 79k in 2020. Ever since this car has been given me nothing but issues. On 6-24-22 for the third time in two years the car would lose all power going 60-70 mph no gas, no battery engine wouldnt work all while driving on busy I-95. I refuse to drive this car any longer as it is not safe for myself and other drivers around me. This car has got to get taken off the road and or recalled as there have been many reports of this same car with the same issues doing this to other drivers.

I have a 2016 hybrid Sonata kmhe34l18ga009859, the dash started flashing and said. . . . . . Hev trouble! stop the engine now! now I have a orange engine light. I brought the car to the dealer. They will look at it and contact me. This car cost me plenty, last year they made me pay for a new engine, it would eat up a quart of oil every two weeks. That is 2 quarts a month.

Engine caught on fire while driving.

Somehow, either by design or manufacturing defect, a part in the headlamp assembly melts and causes a gap in the illumination of the lights while driving. Technicians have said that this is a progressive issue, rather than some sudden onset, and multiple people have said they've never experienced this before but are having this issue with the Hyundai Sonata.

Hybrid system shut down while driving on i5 freeway at 60mph speed. Lost power completly finding myself in a very dangerous situation barely making it to the shoulder without being hit by other cars. This happened twice after 2 recalls performed on the car. Knock sensor replacement and software update. First recall was attempted by Hyundai of kirkland wa. Hev system failure and multiple lights turned on while driving on the freeway the following day. Car was towed to lee johnson in everett wa and I was told the recall was not performed correctly. After repair, same thing happened the following day. Hev failure and multiple lights turned on finding myself once again in very dangerous situation on the same busy freeway. Manufacturer is not taking this seriously. I see they have lots of vehicles with the same problem. Please investigate this failure before somebody dies. Next will file a police report. Car still at the dealership with no news on what might cause this. Has been at the dealer for over a week.

While driving on the highway in michigan I noticed the engine rpm not functioning properly. The timing on the engine was off and the shifting was irregular. I pulled over to the side of the road with fear it was going to do more damage internally to the engine. If I had the cruise control on I was in fear of the engine malfunctioning and causing damage to other vehicles on the road. Upon further inspection I noticed the variable valve censor connector had an electrical shortage and burned a hole right through it. I was afraid of more electrical damage that could have turned into an engine fire. So I didn’t drive it anymore.

On 04/09/2022 around 6:30 pm edt, while driving on the florida turnpike at the posted 70 mph in orlando FL, the 2015 Sonata hybrid suddenly shut down in the center of 4-lanes with heavy traffic. The engine would not run and only sputtered and jerked when I gave it any gas. The display screen lit up with multiple failure symbols including the hybrid system failure, lane detection failure, and several others. I exited the turnpike and had a local auto store scan the vehicle finding the following dtc’s: 1. P1326: excessive connecting rod bearing wear 2. U0293: lost communication with hybrid powertrain control module 3. U1004: not certain the vehicle was checked and found to be full of oil. The vehicle was serviced at the Hyundai dealer on 02/25/2022 where they specifically updated the “excessive connecting rod bearing wear” knock sensor software along with a turn signal issue. Having the engine go into a default mode at 70 mph in heavy traffic was a near disaster. A simple warning would have been adequate to all me to safely navigate to the roadside.

The contact owns a 2016 Hyundai Sonata. The contact stated that while attempting to start the vehicle, the vehicle failed to start. There were no warning lights illuminated. The vehicle was not taken to be diagnosed or repaired. The manufacturer had not been notified of the failure. The approximate failure mileage was 54,000.

If I drive long distances for 30 minutes or more and then stop in somewhere and shut the vehicle off. Once I try and start it, it will give the yellow cil check engine light and the hev error, bring car to dealer. You have to wait approx 15-25 minutes and then it will start up again. I also seem to notice that it happens even faster when I put the transmission speed control into high performance. The battery seems to overcharge and go well past the halfway mark almost to 80% and then once I power off and back on vehicle, I get the hev error message and must wait 15-25 minutes before it will start.

The car is flash on dash boards check hev and turn off the engine cause my car to idle. Turn off my car for 20 mins signal gone then 2 weeks later randomly does it again. Car also flash check breaks on dash boards and turn off the engine and it shut my whole car off.

I was traveling at 65 mph+ in heavy traffic on Friday rush hour when all dashboard error lights came on and then a banner that said turn off engine now. I had no acceleration and fortunately was at a point on the highway with a shoulder where I was able to pull over. I waited in the vehicle with high speed tractor trailer traffic passing close by. The vehicle was towed to the dealership. They replaced the hybrid battery . A week later the identical failure happened at highway speed. The vehicle is still in the shop for the second identical failure.

In January of 2022, my vehicle experienced a complete power loss while driving to work, leaving the car coasting down the road. A check hybrid system warning came up on the dashboard, along with several other warning lights, including check engine. Luckily, I was able to pull over without an accident occurring. Once stopped, the vehicle did restart and got me to and back from work. A diagnosis effort made at a local Hyundai dealership was unsuccessful as they could not replicate the problem and found no error codes in the auto's cpu system. I continued to drive the vehicle, hoping it was a one time deal, but since then, the identical situation has occurred three more times. I was extremely lucky that I had been in a position to safely pull off to the side of the road. The car has not been driven since March 19, 2022. After researching this scenario online, it appears to be the exact situation reflected in the Hyundai recall campaign 175 from 2018, where the dealership remove the original vpd module and replace it with a battery management system (bms) that contains an overvoltage protection device (opd). The recall is said to have been done on my vehicle, but the exact situation has reoccurred. Every time time the car lost power, it was preceded by a shuttering feel in the car, an alarm would go off and the propulsion system would just shut down and the check hybrid light would come on. Hyundai's only response has been to drive the car until it fails again (can you believe that?) and bring it in again for diagnosis. Even if that were to be done, the technicians and others on the road, would then be put at risk, as well, if they drove the vehicle in an attempt to get it to fail. I am the second owner of this car and the recall was supposedly done prior to my purchase. I now wonder if the dealer knew of the problem and that is why it was $2k below kbb. I cannot safely drive the car and can't sell it without loss once this safety issue is revealed. Thank you.

The contact stated that the vehicle seems to stall without warning and shut off due to the fuel pump. The contact stated that upon doing a diagnostic check the code that came back was related to the fuel pump.

The hybrid system shuts down while operating, gives warning "check hybrid system, turn off engine" this has happened twice. Both times the dealership cleared the codes and can't duplicate the issue at their facility. One time this happened while traveling approx 70mph causing the car to immediately decelerate which is a potential safety issue.

The contact owns a 2016 Hyundai Sonata. The contact received notification of NHTSA campaign number: 21v749000 (exterior lighting, electrical system). The contact stated months later, the driver’s and passenger’s headlight fault warning light were illuminated.

Car unexpectedly stopped working and became disabled while trveling 40 - 50 mph on the freeway. Complete loss of power. Danger of a collision on the freeway. All dash lights and warning lights came on. Car would not shift and would not accelerate. It was unsafe to drive and could hardly move off the road. The first year I had the car the engine light came on and loss of power. I took it to the dealership immediately. Whenever I took the car to the dealer they said there were no codes and the car was was fine. The entire time I owned the car I would lose power on inclined roads and engine light would come on and off. Last week November 18 the car stalled and could not drive uphill again risk of a collision from the rear. I took the car to the dealer they said the car was fine. The dealership has never tried to fix the problem and claimed they could not duplicate the problem. Today 12/1/2021 the car stopped operating on the freeway completely and I had to tow it to the dealership. This car has been a safety hazard within the first year and Hyundai has done anything to address the problem.

I recently totalled my car due to "following to closely" which I didn't have gap insurance. Truth is I signaled to go right lane when the car in front thought inwas going left due to faulty recall problem and we both went right, I lost control and hit a rail and damaged car unfortunately.

When I was at work the engine gave up with no warning and could have gotten very dangerous for me. When I called the dealership they said because my car was totaled, but when I called NHTSA they told me that they didn’t have the remedies. I just thought that was strange. I need my car to work so if I can get a response as fast as possible that would be great.

My 2016 plug in hybrid Sonata repeatedly inidcates that there is "high system temperature switching to hybrid mode. " this first happened on my first long trip in the car in 10/21 and has happened repeatedly since. This happens at all temperatures, including moderate temperatures (mid 70s). It seems to happen randomly, such as when battery has several miles of charge left in it, when it is fully discharged, and repeatedly when the car is already running in hybrid mode, which a driver could interpret means that the engine is about to shut down, as I did on a long trip. I have taken it to two separate dealers, and the only thing they did was replace the fuel pump, which did not solve the problem. In addition, the battery life has reduced greatly, despite the fact that I always fully discharge and recharge the batter. As you can see from the attached Hyundai forum comments, this appears to be a prevalent problem for this make and model car and no relief from the manufacturer appears to be on the horizon.
