2017 HYUNDAI SONATA Complaints

Drivers Side front Seat Belt will not retract and is loose when the seat belt is in use while operating the vehicle

Engine is consuming lots of oil. There are recalls on Sonatas but mine is not included, although I have a 2017 Hyundai Sonata Sport with a 2.4L Theta Engine produced in Alabama which are engines that are having defects with oil consumption. 2-3 months I was trying to get car into a dealership for inspection of engine because I kept having to add oil. They would not provide a loaner & I could not afford a rental at time or go without a car. In October 2022, I had to I take car to Hyundai in Trenton, NJ because engine light came on & car was jumping. Spark plug in cylinder 4 blew from low oil. On report from dealership that's exactly what is written on it. They replaced spark plug & got approval to start oil consumption testing. Had to drive 1,000 miles. Returned car & was missing 3 quarts of oil. Had to drive another 1,000 miles, 3 quarts of oil missing again. They performed top engine cleaning saying that could help eliminate the problem. I drove 1,000 miles after cleaning & was still missing 3 quarts of oil. In January 2023, dealership told me they'd put request through for a new engine. I called 1 month later giving plenty of time to have a response. They didn't put request through. Said I need to do more testing & had to leave my car there for a few days with no loaner provided. Why didn't they tell me this 1 month prior & why has no one called me to inform me of this. I can not afford a rental, miss work & my child miss school. We missed a ton since dealing with this issue & I've put out over $1,000 on rentals, oil, damages, deductibles, etc since this started. I contacted a Hyundai case manager & they are still going back & forth with dealership 2 months later. My car is obviously burning a lot of oil & after 3 tests & 6 months I should not have to go through this. In the last 1 1/2 months, I've had to replace spark plug in cylinder 1 twice & cylinder 4 once & constantly have to add oil. My cars shows ALL symptoms of the current issue with engines.

Hyundai has an active recall and open service bulletins for an ongoing issue with Knock Sensors in 2017 Sonatas (my vehicle is a 2017 Hyundai Sonata Sport). Over the last 18 months... the vehicle has been in for service 6 times... 4 in the last 6 weeks... due to ongoing issues with the knock sensor causing the vehicle to go into "limp mode" and causing the vehicle to decrease speed to a max of 60mph. There is no pre-warning for when the sensor will trip and cause the issues... which means if a vehicle is on a highway traveling at a speed of 70mph or more, and the sensor trips... the vehicle will decrease speed down to 60mph maximum. The protocol I am aware of for the repairs... was a first step software update... 2nd step replacement of the sensor... 3rd step replacement of the engine. In 6 attempts to remedy the issue... Hyundai has refused to authorize the appropriate steps to complete the repairs and replace the engine, causing my vehicle to become a hazard on the highways without warning to myself as the driver, or other vehicles on the roadway. **Note, the most recent occurrence of this was 4/22/23.**

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.

Purchased a used Hyundai Sonata in June 2020 when it had almost 57,000 miles on it. Got the car regularly serviced and provided receipts to Hyundai on the national level as well as the local dealership. Received the following claim number - Hyundai Motor America Case#: [XXX]. [XXX]is with the Dealership in Dallas Texas and they car is with his dealership. Have also been dealing with[XXX] at Clay Cooley Hyundai Mesquite [XXX]. The engine does not work and needs to be replaced. Hyundai should be responsible for replacing the engine. The car has only around 76,000 miles on it. Hyundai Mesquite is threating to tow the car and possibly have it junked if it is not picked up. I cannot afford to pick up a car that does not operate. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I purchased my vehicle in November 2022 from Honda Dealership. It was making a noise and “drove funny” I asked them about it and I was reassured the vehicle was in 100% working condition and they were not allowed to sell “bad cars”. So, I let it go. Since I purchased the car I have maintained regular oil changes and service on it— I just bought the car! I have been getting oil changes a lot sooner than I should, and every-time I take it to the shop they say it’s bone dry. Current: my car recently stopped working without any warning at all. I got a diagnosis from the mechanic that my engine failed due to pistons and rods. I did some research and found my car listed for a recall for campaign 953. And I am not the only sonata owner experiencing this problem.

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.

I was driving southbound on I429 approaching the Vineland Wintergarden (FL)exit. approximately .75 miles from exit, a bit of an uphill. I heard a ticking noise, then suddenly the car went silent. The screen lit up with every sensor flashing. It took me a few seconds to realize I was in potentially deadly trouble. The car began slowing from 70 MPH to maybe 25MPH as I crested the last hill. To add complications, that stretch is under construction and does not have any shoulder. I could see a wall of cars streaming ever closer in my rear view mirror. I believe my hazzard lights probably saved me from a crash before gliding the last 1/4 mile to the exit where I was able to finally pull over to safety.

On February 11, 2022, I took my car to the dealership because my oil light came on. I was told I had no oil in the engine. So they said to get an oil change and that would take care of the problem. Nope. It has not taken care of the problem. My car burns oil. I have taken it to 2 different Hyundai shops. One just kept changing the oil and never submit the paperwork until I got really upset about bringing my car back a month after having the oil change. No help. I have called Hyundai customer service no help at all. In January 2023 I went to start my car and it started jerking and shaking and spitting out oil threw the tailpipe. The car would not move. My garage door was covered with oil. I had it towed to another Hyundai dealership they kept the car for a week and told me that it needed a new spark. New wires because it was covered in oil. I'm out of $3000.00 including all the oil changes and the work that was done. Oh yeah, I was told to bring the car back after 1000 miles. I brought it back in March 2023. They started the oil consumption test. I was told to bring it back on that Thursday the 5th. I took my car back and the dealership would not accept my vehicle. Wouldn't let me leave it for my service guy nothing. I called the next day for my service guy and they said he didn't come in today. I even filed with the BBB Auto Line. I found that information in my 2017 owners handbook supplement did not help closed my case. They didn't even call or asked me any questions. No help. Stuck with a car I have no confidence in. I don't know if the engine is going to blow because the oil gets low or if it's going to sketch on fire because theirs no oil in it.

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
