2015 HYUNDAI SONATA Electrical System Problems

The contact owns a 2015 Hyundai Sonata. The contact stated while driving 60 MPH, the vehicle stalled without warning. The contact coasted the vehicle off to the shoulder of the highway and the vehicle was towed to an independent mechanic. The contact then discovered that the vehicle was included in NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) which the mechanic linked to the failure. The vehicle was then towed to a dealer where she was informed that the part was on backorder. The manufacturer was notified of the failure. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The vehicle was not repaired. The failure mileage was approximately 100,000. Parts distribution disconnect.

after taking my 2015 sonata eco to the dealership for campaign 993; campaign 210; and, campaign tww 15-17 I have experienced the following issues: RIGHT TURN SIGNAL STOPPED WORKING ALARM GOES OFF 5 MINUTES AFTER LOCKING THE VEHICLE DASH INDICATES MY REAR DRIVER SIDE DOOR IS AJAR WHEN IT IS LOCKED Prior to having the service done my vehicle did not have any of this issues. RUSNAK Hyundai Inland Empire has not been helpful in resolving these issues. I am being asked to pay to diagnose the issues that were not present prior to the software updates.

“Hybrid System Alert” comes up on the dash and the system shuts down, all electrical is lost including HAZARD LIGHTS and the ability to put the car into Neutral. Since the car shuts down Hyundai says they cannot retrieve the code to solve it. It has been happening on and off for over a year and I’ve been stranded on a dark road with no lights on the car and no ability to push it off the road. HYUNDAI IS NOT HELPING! They need to recall these cars as the issue is widespread. The car restarts after a day or so, but in that moment it is not driveable and very unsafe. It’s clearly a flaw, as there’s no code to be found. It needs to be recalled and fixed. AAA has towed me or come out several times and cannot understand the problem.

My car was stolen 1week after the recall was performed that was supposed to immobilized the engine. The recall did nothing and now I'm left with the aftermath.

A Aknocking noise from the engine that increases in frequency as the engine rpm increases. A Reduced power and/or hesitation and vibration. A Illumination of the "check engine" light in the instrument cluster.

Sensors lights would indicate an issue and would disappear sometimes without any reason (mainly Check Engine and Tire Pressure Sensors). Indicators would trigger the opposite direction (indicate right and the left indicator would turn on). Burning more fuel than expected. Primary fuel pump stopped working resulting in car stopping in the middle of the road.

Engine keeps losing power not sure why & also abs brake system out of nowhere when accelerating in freeway they automatically brake sometimes for safety feature

After taking my car in multiple times to be serviced for a "Hybrid System Warning" mid last year, they were unable to read any error codes or diagnose any issue. I took it to two separate dealerships with no luck fixing the issue. I then completely broke down due to the same "Hybrid System Warning" on the highway on 7/26/22 heading to Pigeon Forge, TN with two children in the car. I had to have my car towed to the closest Hyundai dealership in Knoxville. They were unable to diagnose and fix my car within the timeframe I was in town. Since Hyundai would not provide me with a loaner, I had to get a rental car to get home that I was not reimbursed for. We ended up paying out of pocket to replace the safety plug/fuse and the power relay assembly on 8/9/22. After having the car back...

When automatic headlights are on there are time that the headlamps will turn off when engaging the turn signals until turn signals are disengaged.

After driving for 15 or more minutes, the power steering fails. The warning light for the power steering and stability control turn on at that moment, as well. This failure occurs while driving and the wheel jerks a bit if the car is in a turn. There was a power steering recall for other Hyundais of the same era, which is very coincidental.

Alternator tensioner bracket broke, causing the alternator to hang loosely, which caused the car to gradually lose electrical power to all accessories and safety equipment due to the serpentine belt being loose from the broken bracket. During traveling immediately before failure, the battery warning light illuminated on the dash panel, going on and off intermittently. Thereafter, I began losing control of all my electrical safety features, including power steering, blind spot detection, lane departure warning, forward collision warning system, and eventually power to my entire vehicle as the battery was drained of all charge. At the time of events, my family of 4, including a 2 year old and a 10 week old, were all occupants of the vehicle. With the power of the vehicle declining, the power steering was activating/deactivating intermittently causing the car to jerk one way or the other unexpectedly. Had we remained traveling on the highway...

This is the third time this has happened. The car just starts to beep and stops working wherever it is. Its died on the highway and another busy road during rush hour causing a dangerous backup in which the police needed to be called. The car just beeps and flashes on the dash "Hybrid System Warning! Safety Stop and Do not Drive". Also, "check charging system". The car just stops and basically dies on the road when this light comes. When this happens the steering wheel does not really work and the gas/breaks have limited function. This could cause a major accident on a major highway or even off of a highway. I am quite surprised that there has not been a recall for this serious safety concern.

The power steering started malfunctioning and then caused all warning lights on the dash to illuminate including check engine, power steering, abs, and after coming to a stop and waiting several minutes the lights went off but power steering was still not operating correctly

The contact owns a 2015 Hyundai Sonata. The contact stated that the TPMS warning light illuminated. The contact then stated that the steering wheel became difficult to maneuver. The contact stated that she had to use the shift release button to shift gear. The contact then stated that all the lights on the instrument panel failed to illuminate. Additionally, the contact stated that the vehicle was taken to the dealer where it was diagnosed that the hub sensor needed to be replaced. The vehicle was repaired however, the failure recurred. The vehicle was not diagnosed or repaired. The contact referenced NHTSA Campaign Number: 14V325000 (Steering, Electrical System). The manufacturer was notified of the failure and the contact was informed that her vehicle was not included in the recall. The failure mileage was approximately 129,000.

While I was driving, my check engine light came on. It wasn’t flashing so I was going to continue driving to a parts house (because the dealerships around me were closed) and have them check the codes that were present. Immediately after I had that thought, I noticed the car was smoking and the battery light and the traction control light had come on, so I proceeded to pull over and shut the vehicle off. I got out and noticed the hood had soot on the edges. I called 911 and watched the car go up I’m flames. This all happened in less than a mile. I noticed a fluid of some sort had sprayed out of my vehicle onto the road and the underneath the vehicle was coated in the fluid. This is still being investigated but I know of a lot of Hyundai/Kia vehicles have caught on fire...

The issue is with the hybrid system, which malfunctioned and apparently ruined the rest of the car. The damaged components are adding up to over 75% of the car's value. The vehicle slowed and stopped suddenly on a busy road when the issue started. Currently, it has been inspected by two different shops and they have both given me the same diagnosis.

This is yet another incident of a Sonata Hybrid hybrid flashing a warning to the driver and the the engine shutting down. This time it was Sep 7, 2022 in Morristown, TN. A brief internet search led to this: https://www.tsbsearch.com/Hyundai/17-HC-003-1 indicating that the issue is known to Hyundai. This is definitely a safety issue, this is a known problem, why was no recall issued?

The contact owns a 2015 Hyundai Sonata. The contact stated that after having her vehicle serviced under NHTSA Campaign Number: 21V749000 (Exterior Lighting, Electrical System) the exterior and interior lights would turn off while driving at various speeds, with the check engine and oil warning lights illuminated. The contact also stated that upon using the turn signals, the headlights would intermittently turn off; however, the headlights would turn on upon toggling the light switch. The contact had initially taken the vehicle back to the dealer where she was given a diagnostic fee to determine the cause of the failure. The vehicle was then taken to an independent mechanic where she was informed that the E-CVVT actuator was defective. In addition, the contact also stated that the vehicle would hesitate upon depression of the accelerator pedal or lunge forward upon depression of the brake pedal. The independent mechanic linked the failure...

When auto lights are engaged and the blinkers are engaged, the light will turn off and it will blink in the wrong direction for a few times and then blink the correct direction. While in auto lights and you turn a curve they will sometimes go off. Now I have an issue with my AC - it goes on and off randomly. Had it looked at and they cannot find an issue with the components but said it could be an electrical issue. BYW, Hyundai replaced the motor in this car as well because it had so many issues. I was told the issues now could be caused from them replacing the motor and causing an electrical issue. The paint is also peeling and they had a recall on the paint, but the paint on my car didn't start peeling until after their warranty had expired. This is a known...

Multiple times, when the car start up and is put in to reverse, there is no throttle response. Simultaneously, it can not be put into the manual gear select mode and the car lurches into second gear.

My ABS lights came on and then minutes later my check engine light kept blinking while my car kept stalling or not let me accelerate in the middle of traffic. It’s like the engine dies but the car is on. It only stalls for a second then accelerates then stalls again and accelerates. Almost caused an accident. Seems that this is a problem for a lot of these models. It’s just crazy how it all happened back to back. My car has been running fine otherwise till that happened.

While driving on the interstate, the car began to jerk, and then the engine proceeded to rev as if the car needed a power boost to continue performing. The dashboard then said "Hybrid System Warning! Stop and Do Not Drive" and then the car would no longer accelerate and I had to pull over. This was an extremely dangerous and unsafe situation to be in, and unfortunately, the error only presents itself while driving so the mechanics are unable to get a code that clearly defines the issue that needs to be resolved. I have spent numerous hours on forums with complaints from Hyundai Sonata Hybrid owners who had the same issue and have visited various mechanics to fix the issue, only to end up having the issue arise yet again, further endangering their lives on the road. I believe the best solution forward is to take a serious investigation...

The powered driver seat returning from a reclined position can get stuck in the recline position for some unknown reason. The seat motor, electrical wiring system and the switch have all been examined and replaced and yet for some unknown reason it continues to occur. Two different mechanics thought it was the switch for the seat being faulty but its been replaced twice and still this issue can occur where the seat after reclining any amount the seat will remain in that recline position for an extended period of time (multiple days) and can if reclined completely, remain in the full reclined position unable to return in the direction so as to raise it to a normal seated position. The seat switch will only recline but will not return back to the seated position to any degree. All of the other swithces and buttons with the drivers side seat continue...

2 days ago my car had red orange like engine light came on while i am driving on [XXX] near [XXX] . next to [XXX] my car stopped running so I pull over and I call my local mechanic who sold me the car. JS AUTO In SANTA ANA, CA. He came in a towing truck. [XXX]. ALSO [XXX]. THEY WORK IN JS AUTO REPAIR MECHANIC SHOP. HE ALSO PUT A ENGINE IN MY SONATA HYBRID AND REDID THE MILEAGE ODOMETER IT WAS 49000 but the DMV REGISTATION PAPER SAID 146900 any way.

HE start the...

While driving, the following warning appeared: Hybrid System Warning! Safely Stop and Do not Drive. The vehicle was turned off and restarted, due to the fact that this same warning appeared in the summer of 2021, where it was towed to the dealer and they were unable to discover any problem. When the vehicle was taken to the dealer this time they found the code P1B70, high voltage battery to low, there was a flash update for the BMS module to correct the issue. My issue is that you do not always have a appropriate spot where you can stop the vehicle and leave it for a tow. Perhaps this flash update should be installed in all 2015 Hyundai Sonata Hybrids as a recall so as not to leave the drivers in an unsafe condition

Fuse-High Voltage blow, no continuity. Forced us to pull off one lane highway. Turned off car and it would not start after that. Car displayed "Hybrid System Warning! Safely Stop and Do Not Drive" on dashboard, while driving.

While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again. Here we are in 2022 and it stalled again. Why can't they just replace the engine? This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.

Out of the blue, I heard a very loud knocking noise coming from my engine. I was driving my children to school and as I hit the gas pedal the less power my car had. Not only would it not accelerate much but even the lights would dim. I am now paying over $400 a month for a car that I can not drive and walking where I need to go. My vin number does not qualify me for the engine recall Hyundai has, even though my car is the right year, make and model, engine size and problem that the recall is for. Awesome right?

The car caught fire. I only had the car for 3 weeks. I had just started the car for work. There were no warning lights on. If some unknown guy have not told me to get out my car i would had died.

Check engine light on. Taken to hyundai dealership for recall repairs. At the time, 3 recalls on vehicle. Informed that check engine light was on due to recalls. Dealership kept car for 1½ weeks and notified me that 1 recall (filter) was not completed because parts are on back order. Dealership had me pick up vehicle and said that it is okay to drive car; however, after calling another Dealership, the Service rep informed me that cars should not be driven while engine filter recalls are open because it could potentially further damage vehicle. Vehicle has now been sitting in my garage for over 2 months and I'm making payments for a car I cannot drive.

I was driving at 55 mph and vehicle stall and cut off pulled side the road tried to crank back up and nothing happened. after each oil change no oil show on stick and also when i get an oil change they tell me barely any oil in vehicle. this has happened every since i purchased the veh on Dec 10 2019

We received a notice for an IMPORTANT Safety Recall for our 2015 Hyundai concerning a turn signal malfunction. According to the information given to us, this problem could understandably be very dangerous and life threatening. So we tried to schedule an appointment at our nearest Hyundai dealer, but were told they weren’t even taking appointments until January (So much for taking care of a dangerous situation). This dealer was San Tan Hyundai in Gilbert, AZ! If this repair takes only an hour or so as the notice predicted, I’m wondering why such a delay for an emergency service? We continued to call around and finally scheduled for a Dec. 1st appointment at another dealer. That we can live with, but their is no excuse for a similar dealer not being able to deal with this problem sooner. The person on the call was not very polite, which is par for...

The contact owns a 2015 Hyundai Sonata. The contacts son stated while driving approximately 40 mph when the vehicle's steering wheel became hard to turn. The power steering warning light was illuminated. Upon investigation, the contact associated the failure with, NHTSA Campaign Number: 14V325000 (STEERING, ELECTRICAL SYSTEM) however the VIN was not included. The vehicle was taken to a dealer where it was diagnosed with being an electrical issue. The vehicle was repaired but continued to experience the same issues. The manufacturer was informed of failure and filed a complaint. The failure mileage was approximately 47,000.

Turn signal sometimes does not work or causes opposite side to activate leading to increased risk of crash, no remedy provided currently from current recall on vehicle. There's no warning as to when this can happen which leads to driving the vehicle a risky bet.

The contact owns a 2015 Hyundai Sonata. The contact received notification of NHTSA campaign number: 21V749000 (Exterior Lighting, Electrical System) however, the part to do the recall repair was unavailable. The contact called the local dealer who stated that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was notified of the issue however, no further assistance was provided. The contact had not experienced a failure. Parts distribution disconnect.

I was driving under normal conditions and every warning indicator light and chime went off, speedometer and tachometer gauges went to zero, digital display of speedometer went blank. I immediately pulled into a parking lot and shifted into park. I called the nearest Hyundai dealer to speak to a service rep, but was told they were busy and would call back. The car would not shift, it was locked in PARK. I turned it off, waited and turned back on, all warning indicators were still flashing, but I was able to shift into drive, and went straight to the dealer. Diagnostics by dealer was that "CEL WAS ON DUE TO HISTORY CODES. CLEARED CODES AND TEST DROVE THE CAR AND EVERYTHING WORKS AS DESIGNED." 200 miles later, same problem. I will gladly make my vehicle available for inspection upon request. I searched the internet and found others were having same...

VEHICLE CONTINUOUSLY ALERTS THAT THE HOOD IS OPEN WHEN IT IS IN FACT CLOSED. HOOD LATCH IS IN GOOD CONDITION. THIS HAPPENS VERY RANDOMLY, EVEN WHILE DRIVING.

THE AIRBAG DASH LIGHT INTERMITTENTLY COMES ON AND OFF, IT HAS THROWN A B1490 CODE ALTHOUGH THE CAR HAS NEVER BEEN IN ANY MAJOR ACCIDENTS BEFORE. I HAVE READ THAT IT IS A COMMON ISSUE AMONG VEHICLES LIKE MINE, HOWEVER THERE IS NO RECALL THOUGH I'VE SEEN MANY COMPLAINTS ABOUT IT ON ONLINE FORUMS.

THE RECALL OF THE ECU FLAMMABLE SOFTWARE RECALLED WAS FIXED AT HYUNDAI TYSINGER DEALERSHIP IN HAMPTON VA JULY 2020 WHEN I RETRIEVED THE CAR THE TPMS SENSOR WAS ILLUMINATED THEY ASSURED ME THE SOFTWARE PKG THEY UPGRADED AND OTHER SERVICES PROVIDED WERE NOT RELATED TO THAT HAPPENING. I HAD A SECOND OPTION AT RNR HAMPTON VA WHO ENSURED ME THAT REPLACING EACH TIRE VALVE WOULD FIX THE ISSUE. THEY CHARGED ME 400 ON 9/16/2020 FOR THAT SERVICE WHEN THE CAR WAS PICKED UP THE TPMS SENSOR NEEDED TO RE-SET ITSELF AND DRIVING IT WITH IT WAS FINE - IT WOULD ASK TO PROMPT ME TO RE-SET IT AND / OR DO IT AUTOMATICALLY THE NEXT 24 HOURS - IT DID NOT DO THAT - IT IS JAN 18 2021 I JUST HAD MY DIAGNOSTIC FOR THE TPMS SENSOR FOR THIS 2015 HYUNDAI SONATA AT HALL AUTOMOTIVE THEY ARE SAYING ALL...

VEHICLE DRIVER RECEIVED AUDIO AND VISUAL ALERT WHILE DRIVING AT HIGH RATE OF SPEED THAT THE "HYBRID WARNING FAILED AND TO CHECK HYBRID SYSTEM-TURN ENGINE OFF" AND TO PULL OVER SAFELY. HOWEVER, THE VEHICLE LOCKED AND LOST ALL POWER MAKING IT IMPOSSIBLE TO SAFELY EXIT THE INTERSTATE ALMOST INSTANTLY AFTER THE ALARM. UPON RESEARCH, I MANAGE A LARGE VEHICLE FLEET, WE HAVE MULTIPLE OTHER SONATA'S WITH THE SAME ISSUE-AND THERE IS A TSB FOR THIS KNOWN SAFETY FAILURE (17-HC-003-1).

THE CAR HAS FAILED TO START ON MULTIPLE OCCASIONS. I ENTER THE CAR, PRESS THE BREAK AND THE PUSH TO START BUTTON, AND THE CAR FAILS TO IGNITE. IT HAPPENS NORMALLY WHEN IT IS COLDER, BUT WILL STILL DO IT WHEN IT IS WARMER OUT.

HEAD LIGHTS RANDOMLY GO OFF WHILE DRIVING AND DO NOT COME BACK ON A LOT OF THE TIME.THIS HAS BEEN HAPPENING A LOT AS OF 48000 MILES AND DEALER SAYS THEY CAN NOT FIND REASON.
