2017 Hyundai Sonata Electrical System Problems

Here is your updated review with that included: ⸻ I am very disappointed with Hyundai Motor America and the service I received at Hyundai of Renton. I own a 2017 Hyundai Sonata and received a letter about a required software update and ignition cylinder protector due to known theft issues. I went to the Renton dealer for the recall service. They performed the software update and were supposed to install the ignition cylinder protector. Unfortunately, my car was later stolen because of this exact issue. The ignition was damaged during the theft, and I had to replace it myself just so I could drive the car. When I returned to the dealer, they refused to install the ignition cylinder protector, saying the ignition was broken. It was broken because of the theft — which happened due to Hyundai’s known defect. After the recall software update, my key fob also stopped working properly. I went back to the dealership, and they refused to fix or properly reprogram my key fob. On top of that, the service manager, John, was very rude and unprofessional. This has been the worst experience I’ve had with a vehicle and a dealership. Because of this situation. Very disappointed.

This car is becoming more of a headache than it’s worth. Turned the car on, My car started shaking and my check engine light came on. then I got this message “A possible condition with your engine control system has been detected on a 2017 Hyundai Sonata”

I was involved in a severe motor vehicle collision in a 2017 Hyundai Sonata. The airbags failed to deploy during the crash. I sustained serious injuries and was transported from the scene by EMS. This vehicle has known safety recalls, and I believe the airbag non-deployment may indicate a safety defect.

My Hyundai consumes oil and I have to put oil in it every two weeks! Also my ignition coils has had to be changed 4 times. Also check engine light just came on code saying catalytic converter or oxygen sensor changed oxygen sensor a couple months ago. I purchased it brand new and as soon as I got over 100,000 miles nothing has been going good since then please help also my paint on the top of the car is starting to peel. Will never buy a Hyundai again.

The camshaft position sensor internal rubber plug is faulty and it allows oil to leak into the sensor housing. Ruining the sensor and the brushes and housing. It causes the check engine light to come on the idle races and car takes off on its own. Can’t drive it because it’s to dangerous. Once it takes off then it goes into limp mode and you can’t pull out because of no power. 40000 miles. The internet is full of owners having the same problem

I keep having both my low beam headlight bulbs burning out and one of them started catching on fire. The driver side caught some type of electrical issue causing it to start smoking and eventually melted the connector and lightbulb housing

The makes a weird shutter noise when accelerating and won't crank over 60. Loses power when turning or when going uphill. Sometimes has problem starting. Enging light came on twice blinking, once I changed the battery it went off and was working fine. Now it's back on again after a few weeks. Plus my oil tank still comes on and I've just received and oil change. I just bought the car in August of this year, dealership sold to me with a faulty battery.

HEV battery constantly states that the car needs turned off. Hyundai had to replace my engine as it just died and blew a hole in a pipe

The vehicle itself shakes when accelerating and will start to fail once 60mph is hit. It will also cut out when left turns are made...I have met 4 people with the exact same issues who received recalls but I am not sure why my car is not included. I was almost rear ended on the highway by a semi with my pregnant wife and 4 year old son in the car because of the engine failure.

driving on the side of the interstate, the hybrid battery indicator continuously dipped low. Minutes after continuing driving on the interstate around 50 to 60 mph, every light on the dash came on the vehicle stopped accelerating, and the warning light check HEV system shut engine off started flashing. The vehicle would no longer start again after this. the dealership said that the fuse was being oversupplied, which is what caused the system to fail. This exact situation is listed in a recall for 2013 to 2015 Hyundai Sonata hybrids. After reading the recall notice., my vehicle had this failure due to the exact reasons listed in the recall notice. due to the damage that was caused by this fuse that could not hold enough electricity my wiring harness also has to be replaced. This could be a three to $4000 out-of-pocket expense for me that should be covered under this recall, due to its exact nature of similarities. please assist me. I do not have the complete invoice due to the fact that the dealership is withholding that information until the repair is complete However, hyundai motor is also aware of this issue, and I am filing this complaint for this investigation to be moved with urgency

On 03/16/2024; while driving on I-90 the vehicle at approx 60-65 miles per hr, suddenly stopped, and had to be towed to Matthews Hyundai of Schenectady.

It has happened twice now that check Hybrid system turn of engine comes on. HEV ! And i have to call a tow truck because i cant drive the car.

I can’t drive my car on the highway cause then it will shut off and say HEV system error and I have to shut my car off turn it back on then erase the code with my diagnostic tool. My oil light keeps popping up and whenever I slightly press on the gas pedal or go up a steep hill, it starts to rattle, been noticing my oil burns out fast and I have to replace it when it gets low.

Hello! I bought a car in the USA, I live in another country. Errors that appear in the car are similar to these: [XXX] Еrror appears then, the cogd I give more gas and let go of the pedal. When the engine is heated at different speeds. The scanner showed these errors: P1326 Ignition Control Module - Combustion Quality Input Signal; U0293 Lost Communication With Hybrid Powertrain Control Module; U1004; B2AAA. But the electricians do not know what the reason is and no one can help. So I go for one year with an error ((( Please help! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The hybrid system failure. Chrck engine light is flashing. Abs system failure. Battery failure. Car can't go over 45mph, lost a job because of the issues. I'm afraid the car is going to blow up or catch fire. I'm afraid to drive it. The acceleration is barely there. It's like the car doesn't even wanna go. It sucks through gas like no other.

Driving the car on the freeway, the battery light came on, and after that few other warning lights came on and I pulled over by then the car stopped and didn't turn on. It was scary since I was on the freeway. No other warning prior to that and the car was very well maintained even during the last recommended service everything was checked and no recommendation was made regarding the alternator. It was the alternator that caused the problem according to the dealer diagnosis.

HEV light comes on and the car starts slowing down & beeping. Unsure what the issue is but this started once the car had more than 100k miles on it

I have a 2017 Hyundai Sonata that has had 3 recalls. I purchased the car in 2019 and all three recalls have been issued after 2019. Since I’ve had the car I’ve never taken it to Hyundai to get the recalls taken care of . Until recently I took my car to get the recalls fixed and they told me they had already been taken care of . The gave me the dealers contact information and I’ve never taken my vehicle to them they claim to have serviced my car at 122000 miles and I only have 94000 miles in my car. I believe they used my vin number to summit they fixed the recalls when my vehicle was never at their dealer. I contacted Hyundai and have not received any call back . The recalls for my vehicle are very serious recalls that I need to get fixed . One of them is the malfunctioning of the trunk latch my trunk does not open or close right now. I have a 6 month old baby and I need to put her stroller in trunk and I’m unable to do so. Also my car vandalized twice they tried to steal it. I need the security update . I just don’t know who I need to contact to help me get this resolved .

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

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.
