general problems of the 2017 Hyundai Sonata - part 2

National highway traffic safety administration 1200 new jersey avenue, se washington, DC 20590 subject: anti-theft upgrade request and complaint dear sir/madam, I am writing this letter as an autochthon american woman exercising my rights to conduct commerce and practice freedom of religion, seeking assistance and resolution for a distressing incident related to the theft of my conveyance. I believe that the faulty design system of my Hyundai, which was advertised as reliable, contributed to the unfortunate incident of theft. On [date of theft], my vehicle, a [make, model, year, color, license plate number], was stolen, and it has had a severe impact on my ability to conduct commerce, generate income, and practice my religious rights freely. The theft has left me under duress, causing immense stress and a crippling financial situation. The advertised reliability of Hyundai vehicles has proven to be far from the truth in my case, as well as the experience of many others. I am seeking assistance and action from the national highway traffic safety administration to address this issue and improve the anti-theft measures in Hyundai vehicles. My inability to utilize my vehicle has significantly hindered my daily life, preventing me from engaging in productive work and fulfilling my religious obligations. I implore the national highway traffic safety administration to thoroughly investigate this matter and take necessary measures to enhance the security and anti-theft features in Hyundai vehicles. I kindly request the following actions: 1. An investigation into the reported faulty design system contributing to the theft of my vehicle and its impact on others. 2. A prompt recall and implementation of an effective anti-theft upgrade for all affected Hyundai models to prevent similar incidents in the future. 3. Adequate compensation or support to help alleviate the financial burden caused by the theft and its consequences. I am aware of the national highway traffic safety adm.

Multiple error codes popped up on multiple occasions. Lost power and last code was "check hybrid system shut off engine" hev system error. Battery, engine, collison, and maintenance error lights showing on dashboard. 06/ 22 - dealership inspected and worked on safety recalls only. Nothing else was found. 10/22 - fix finder report showed error code p0455. Vehicles reset itself somehow over the weekend. No issues on Monday morning. 11/22 - lost all power. Towed to dealership. They reset codes p0455 and p0456. Test passed w/ no further issues. 07/09/2023 - driving 65mph and loss power. Multiple error codes. Slowed to 20mph and made into driveway. Hev shut off engine came on as I stopped.

I have financed my Hyundai Sonata sport 2017 in December of 2019. I have not had any issues until this current year of 2023. I have noticed that with every oil change that I receive that I would have to go back to the dealership or certified mechanic a month or two earlier. I personal checked for leaks but seen no signs of why I had to get constant oil changes. Recently, when driving on the highway speed limit at 70 mph and my car went to 60 mph. The engine light came on but no other warning. I stopped the car, check the oil level which was pretty low and topped it off. I let the car sit for a short while as I was only 5 mins away from home. Soon as I made it back, I check the oil level again which was in the line. Check for visible leaks. I figured my car shook as it did and idle at the speed do to a misfire with the spark plugs/coils which I had already replaced 2 months prior to the incident. I was able to use a car scanner from autozone to check for codes but there wasn't an engine light at all on the dashboard. There was only one code that did show which was p1326 but no engine light or flashing engine light. I then schedule an appointment for an oil change and to confirm that the engine light code was with firestone auto care to analyze the issue. They did an overall check over on the car, checked for codes, and changed the oil in which they found no issues. With driving my car to test if there were any issues it completely shut down and did not want to start. They called me to tell me that the engine was locked. They tried turning the engine over multiple times, but nothing would start up. Due to not knowing what was going on with my vehicle I felt unsafe with driving it as it completely slowed down on the highway. As other cars where speeding by. It gave no indications prior to the incident that anything was wrong. I am waiting to see a Hyundai dealership to inspect my vehicle which they are booked until next month. My car is currently disabled.

The vehicle has stalled in traffic numerous times since I bought it in 2016 creating a traffic safety issue. Without warning the lights on the dash will flash and the car dies. I have worried each time that traffic behind me would collide with my car. #1 1 1/2 years into ownership this occurred. They replaced part of the ev charging system that was overheating on the cars. (recall) # 2 1 /2 years into ownership the air-conditioner failed and the car stalled in traffic due the air-conditioner failing. (replaced under extended warranty) # 3 last year I complained that a hybrid overheat message would come on switching to ev mode and the transmission felt like it was slipping occasionally, and the battery only held 20 miles of charge, rated for 27. They refused to change the battery system under the lifetime warranty. #4 last summer car stopped charging (replaced invereter under extended warranty) this month car stalled on the roadway, lights flashed on dashboard. Could have been rear-ended, had to coast to a stop and restart the car. Took to dealer the said the replaced an ev computer for 5k (replaced computer under extended warranty) 3 days later same issue, stalled on busy street without warning. Took to dealer and the replaced the cars main battery, charging me $450. 00 3 days later it stalled again without warning in traffic, it's not back in the shop. This vehicle has major safety problem. It's extremely dangerous to have a car stall in traffic without any pre-warning. The design is defective. The cars need to be recalled and bought back at full price by the Hyundai.

Electric power steering failure, have taken to the dealer and they told me I need a new battery. I bought one and the problem is still happening. Used to reset after I restart the car but now it won’t.

My Hyundai Sonata hybrid has always experienced issues with a loss of power as well as warnings illuminating on the dashboard which also would result in a check engine light and occasionally a complete shutdown of the car. When this issue was experienced a simple restart of the car would make it run normal again-even the trouble codes would clear out of the system after the 3rd reset (also completely wiping the code history)I was lucky and the car began to “limp” and throw the check hybrid system warning within 5 minutes of a local dealership. They found that the hsg “hybrid starter generator” was faulty via a voltage test. They explained that the hsg would cause the complete shutdown and poor performance of my vehicle due to incorrect voltage. This issue existed for many years and the dealership was unable to identify the source of the issue. This is extremely dangerous and seems to be a common occurrence. I complained about this issue directly to the dealer’s maintenance managers as well as escalated the issue to Hyundai corp they also were unable to determine the part was faulty over many years and even told me to just “reset and keep driving”. Please investigate this issue it can be found all over the internet with a simple google search. I have even met a gentleman in the dealership with the same year Hyundai Sonata hybrid limited and he also was experiencing the same issue-they were unable to identify or replicate the issue when the car was left with the dealer.

My 2017 Hyundai hybrid phev vehicle stuttered and failed to accelerate when the gas pedal was depressed and a warning light indicated a problem which was confirmed as a failed battery in January 2023. I was advised by the Hyundai Sonata service center 13 weeks ago that the vehicle was unsafe to drive due to a defective battery. They have not been able to replace the battery or provide an estimate of when the replacement battery will be delivered. The battery has a lifetime warranty but the Hyundai company and dealership is not providing a loaner vehicle or reimbursing me for rental vehicle while the unsafe vehicle sits in the service center for more than 3 months. Please help.

Hev lights came on stalled car and stated to turn engine off, barely made to a parking lot. Car was towed, in shop Dec 29, 2022 to Jan 10, 2023. Knock sensor replaced, rusty spark plugs slots cleaned out, no communication with power train, case #20817405 June 16, case# 21597503 part a: hev lights again chugging and stalling. Car towed in shop 22 days, returned 7-5-22. Actuator 2nd time failure, knock sensor issue, clogged, emissions were cleaned: part b: Aug 14, to oct 4 2023hev system lights again, car stalled and died then towed : combustion cleaning 2nd time, spark plug corrosion replaced 2 time issue, 4 injectors replaced, recommend replace manifold (which I cannot pay for) dealer tech test drove 2 days and put 211 miles on car, more than we do in normal week driving to work and shopping in shop this time 52 days. This car has been taken in for all recall campaigns. Work done at same dealership every time. Is a Sonata hybrid se I am attaching two files if you need more please let me know. Your date entry below does not allow for each of the 3 times in shop total roughly 85 days four months would like Hyundai to buy car back as no trade in value now and I cannot afford more rental fees and repairs and the balance due of $495. 75 from 1st rental. Car just entering 6 year when first issue started.

The check engine light started flashing check hybrid system turn off engine massage appeared the gas pedal doesnt work and the car jumps the problem happened 4 times so far with me the same problem happened about 5 times with my uncle that drives 2016 Sonata hybrid.

The car lost all acceleration and my check hybrid system light came on. The car would not handle safely to drive. After 3 resets the car finally accelerated as normal. The codes clear themselves before the dealer can check them to give a specific issue. It is not giving the diagnosis for the hybrid issue in the diagnostic log.

I took my car to a shop due to my car having a loud knocking noise coming from the engine bay and lack of acceleration as well as the oil light flickering on and off and once the mechanic inspected my vehicle he said metal particles were being deposited into my oil due to internal engine parts. After picking my car up all the lights on the dash cut on and the car completely had no steering, no brakes, no power but the radio still worked. I barely could turn the steering wheel nor could stop the vehicle due to this and thankfully could coast into an upgrade leveled hill and stop the car. Car would barely recrank or hold power nor would go above 40 mph. Only drove 5 miles to get the car back home safely. Drove back around 3:00 a. M. So there wouldn't be much traffic out in case of something like this happening. Could've been catastrophic!.

Electric power steering randomly fails while driving, causing a huge safety issue.

As I am driving, at random times, typically at cruising speeds of about 40 mph or less, the steering wheel will lock up and I will be unable to steer the vehicle until I turn the car off and back on again. There are typically some warning lights (I’ll try to attach the picture) that pop up and go away once the car is turned off and back on again. No dealership that I have taken it to has been able to diagnose the problem since it does not, to my disdain, occur under their watch (it is not reproduced). This issue puts both my life and everyone in my proximity’s life at risk as I have no control of the vehicle once it locks up. At this point it has occurred for over 2 years that I have had this car. There are some warning signs right before it occurs. First, there is typically a sudden change in the resistance of the steering wheel. Particularly, it will become harder to move the steering wheel left but then turning it right will have no resistance. As soon as this occurs I start to panic because it indicates that any turn at that point will lock the steering wheel. It has occurred this way every single time. Sometimes it happens in the opposite direction and the right side becomes stiff and suddenly any turn in the steering locks it up. This is very dangerous and can potentially kill. This model needs to be recalled!.

My check engine light has came up already three times within each month the codes that appear is p0014 / p1326 I have changed the oil many times and it still appears now my it to the point my car can't be driven it not let me drive it only at a certain limit.

Hybrid system failed, lost power while driving on freeway going 65 m/h during rush hours, rpm gage went down to 0, most instrument light weee lit on dashboard. Speed went all the way down to 40 m/h pressing the gas all the way down. Hybrid system warning light was flashing. Could have been hit by other vehicles on freeway I had to put my hazard flashing signal and wait for the right moment to pull my car off the road and to emergency lane to stop. The first time car was towed to dealer. And dealer was able to confirm the problem. The spent 2 weeks at dealer until the claimed they had to contact the manufacture and ended up replacing a wire harness they thought water got into it, paid over $600 for this fix. Few months later same problem they ended replacing some sensors due to a recall. A week later happened again all 3 time on the freeway. The check engine light was on few months prior to these issue and took to dealer multiple times since was still under warranty. But the problem kept coming back. They replace fuel injector then coil pack, the 3 time I was told the engine needs to be flushed and that not covered under warranty. Not long after that the major issues with the hybrid system 3 times.

The check engine light came on and wouldn't accelerate normally. The speed was delayed and cutting back and wouldn't pass 40 mph. Upon taking it to a local shop it had to be taken to the buying location by road side assistance. After the service department checked into the problem it now needs a new engine. They stated there were metal shavings in the motor. This was transferred by a known problem in the 2. 4 l motor that Hyundai has put in their vehicles with problematic bearings. This happened within 2 months of buying this vehicle. We can't drive it at all now so it's still at the shop.

My steering wheel is locked it’s hard to turn left or right. I go to school in a different city so I drive back and forth from school to home. While I was turning into the parking lot to park my steering wheel just locked while I was trying to park I almost hit someone’s car in the process. I had to turn the steering wheel with both hands tightly to one side for the steering wheel to move. I was so scared.

After travelling on the highway for approximately 1 hour the hev light along with several other lights came on and the engine powered down. The instructions were to turn off the engine immediately . Luckily I was in the right lane and was able to get to the shoulder of the highway and turn off the engine. Tried several times to restart, but same message came up to turn off engine. Had it towed to closest Hyundai dealer for service. They couldn't look at it immediately, but according to them it started the next day and they drove it around (local driving) for 10 miles with no issues. I took the car back and after driving it again on the highway for 1 hour the same problem occurred and I had to have towed to my local Hyundai dealer. It has been in their shop for over 3 weeks and I still have no answers as to what may have caused the problem.

Power relay has been replaced several times, air bags did not deploy with either wreck and loss control of steering causing a crash which bent the frame. Hyundai never once contacted me regarding this defective car they replaced motor in because of knock sensor and im lucky to be alive. On one of the accidents in February there was an error message that popped up right before I had the wreck and it was an error message wrong with the cars transmission system or something like that I had the dealership who said there was no codes on that car and I had my own personal mechanic who had codes pop up on that car that the dealership hid.

The power steering system appears to be failing. There is no indication of the failure prior to failing. When making turns the power steering would randomly stop working, all emergency lights would turn on, and the steering would become extremely difficult to control. This becomes an extreme safety issue when I’m driving around other vehicles. I took my vehicle to a mechanic and they explained that the power steering is electronic, therefore power steering fluid will not fix the problem. Also, there’s an electrical issue with the windows as well. The passenger window can no longer can be controlled by the driver. Lastly, the ac has failed as well. It blows out only hot air. I’ve taken my car to the manufacture dealership and they assessed my vehicle for the ac problem, but they stated that it’s working fine. This is not true because I’ve continued to have problems with the ac, even after many failed troubleshooting attempts. To summarize my report, I have a total of 3 issues in order of importance, power steering, power windows/electrical, and air conditioning unit. My car is available immediately for inspection upon request. Thank you.

Problem began Dec. 2021. Has occurred on 16 occasions since then. Warning light "check hybrid system; turn off engine" comes on while driving. The car then shuts off the engine and there is a 100% loss of motive power. Sometimes is associated with very rough braking with the car "knocking'. " on 3 occasions there has been partial/near complete loss of braking power. All incidents have occurred while under power, so far all while under 45 mph. No accidents yet. Two near collisions from the rear. Hyundai was notified of the problem Dec. 2021/Jan. 2022. After a month of testing they stated the car needed a new plug-in hybrid battery. One was not available and due to "supply chain issues" is still not available 15 months later. Dealership provided a loaner vehicle Jan to sept. 2022. They requested their car back and Hyundai initially agreed to cover the cost of a rental car. I rented a car for 6 weeks in sept. -oct. 2022 at which point a new case manager informed me that Hyundai would not pay for a rental vehicle any longer (note: they did reimburse me the cost of those 6 weeks rental). Hyundai is well aware of the safety issues involved in driving this vehicle. However, they have chosen to ignore them. Their attorney, in a letter to the ohio attorney general's office, blamed the lack of a plug in hybrid battery on supply chain issues (letter was Nov. 2022, at which time the battery was supposed to be available March 2023) and only stated that my vehicle was "drivable. " another warning message "high system temperature; switching to hybrid mode" has been occurring for a couple of years periodically. Since October 2022, the malfunction indicator lamp is always on and 99% of the time the "check hybrid system!" warning light also comes on after about a minute after starting the vehicle. On 3 other occasions the vehicle has entered into "limp home mode" instead of complete shutdown.

The trunk will not open by any means, the button inside, the key fob, the mechanical key, the Smart trunk open feature. Mine is the hybrid and does not have fold down back seats. So there is no way to open it from inside or outside only via the inside of the trunk. It just has 28,045 miles. I called the dealer bob king Hyundai and they did not know if it is under warranty and it will cost $130 just to look at it?.

While going down the highway, the vehicle's check engine, abs, tpms, traction control, air bag, electronic steering & emergency brake lights all came on simultaneously. & at that same time the speedometer & tachometer both dropped to 0, the digital display of the engine temp guage, gear setting & other onboard displays went down while the car was in motion on the highway. I was able to safely pull over to the shoulder but once the car was placed in park the shifter locked & I was no longer able to change gear settings.

I own a 2017 Hyundai Sonata and this week the trunk release would not operate. In checking the release mechanism I discovered a plastic part in the trunk release mechanism had broken. The reason for this complaint is that broken part does not allow the trunk to open manually from the inside of the trunk. If a child of adult person was accidentally or purposely put in the trunk they would not be able to escape. Attached are a couple photos showing the trunk release mechanism with the yellow manual safety release and a photo showing the broken plastic part. This is a safety issue and consumers should not be force to pay to have this part replaced by teh manufacturer.

Car gives warning message to "immediately shut off the car to prevent damage ". . . . This has happened numerous times and Hyundai doesn't seem to have a fix, and doesn't think its a safety issue. This is a safety issue particularly when you are in heavy traffic with no place to move over to shut off the car.

The trunk latch would not open. It would not respond with key fob, interior button, button under the handle or with the key. Forced it open once and then had to force it closed. Stayed closed until repair could be made. Hyundai would not cover cost or repair. There was no damage, short or anything else that would explain why this part failed except for cheaply made plastic part that wore out.

Trunk will not open, with dash button, trunk button, or key. Stationay with $173 perishible groceries inside, will be oderious by the time it gets to a shop. Parked in garage.

I bought the car used from a scam dealership. I had no idea that there was an engine recall in January until it turned off and on just one week after leaving the lot. I brought it back to them, obviously, they said it wasn't their problem. I then took it to college park Hyundai to have them update the knock sensor and diagnose the issue. After an extended road test, it was decided that my problem was an isolated incident. Yet I took it to other dealerships, and pretty much everyone says the same. My dash cam has recorded the moments when the car stutters and fails to accelerate before turning back on a couple seconds later. It has happened on curves and I have nearly drove off the highway due to this. It only happens when the car is reaching about 60mph. I live in MD but work in va. I'm paying high interest for a crappy lemon car. I even contacted corporate Hyundai, and they just laughed and called me stupid for buying a used car. . .

I bought my car November 28, 2017. On June 27, 2019, the interior lights and the license plate light were inoperative. I've brought the car into the dealership I bought the car from three times, but they were unable to fix the problem. Now, my car has been in a different dealership for the past approximately two weeks, and it still hasn't been fixed. If I drive a vehicle without a functioning license plate light, I'm subject to a $30 fine. I've begun to assemble documentation for a lemon law complaint. I'm including the repair invoice for the first time I brought my car into the original dealership and the last time I brought the car into the original dealership. So please disregard the attachment information at the bottom of the forms.

After receiving recall mail, yesterday I left my vehicle at service. They gave me back my car and told me they have fixed it. After driving less than a mile the engine stoped and a yellow light turned on. Again left my vehicle at the same service, today I called them and told me that they will probably fixing it after receiving the part next week. If it won't get fixed they are planning to change the engine. Is this a normal process! and what happens to the value of the car if the engine changes?.

Wirring handss, engine red lights on and can't go over 55 miles, start to shake.

The vehicle is available upon requested inspection. Since I bought the car in 2019 it has made a rattling sound like the engine is knocking. Not a severe knocking, however, it does make a clicking/rattling sound in idle, occurs more rapidly while accelerating, then sounds like a muffled diesel while the engine’s torque is dropping when shifted into neutral coasting on the road. Oil has been changed in its due time. Between 3k - 7k as scheduled. Independent service provider didn’t think it was normal and recommend I check for recalls. I asked Hyundai dealership representative and said it’s a normal sound. Other vehicles I’ve driven don’t sound like this. Even an older ‘96 Buick sounded smoother running. Nothing has failed, caused an injury or accident. Engine light has recently come on. Temperature is hotter, according to the gage, than we’re it has typically sat for the past couple years. The potential risks increased, not knowing what can happen, when the temp rose and engine light comes. . . . . . . . . . . This, aside from previously stated concern, alarm activates (mostly during the rainy cloudy weather) when manually unlocking the car. Having to relook and unlock to silence alarm.

My car is a death trap, I have already been in one accident and too scared to drive it, it just sits in my driveway. When you make a left turn at say a red light the car go's about 5 feet and then stops for 3 seconds, people behind honk at you and then the car rockets forward, I have already been hit once and the other driver took off, so I was left with the bill. The dealership says they can't fix it, even though it has a powertrain warranty. Please tell me what I can do. Kevin sterling 770-406-7782.

I noticed immediately that the car seemed to drag during takeoff. On Monday upon crossing the bridge down lurlene b wallace blvd the car engine shut down in the middle of traffic.

This is the plugin hybrid model. The lithium ion battery cannot be charged sometimes due to overheating condition. If this is not fixed, it might cause a fire or explosion. Sometimes, it will not let you charge. It will not even let you turn off the charge schedule to charge. Sometimes, it stops charging due to thermal problem. Hyundai is not taking responsibility to fix this. Attached photo documented that it did not allow me to switch off the charge scheduler to start charging. I hope Hyundai will address this problem before the car burns up or explodes.
