Everything was displayed in red on the front screen, it was automatically parked, and the steering wheel did not move. This happened late March/02/2024 last Saturday night, so I called AAA twice and had them toward to my house. March/04/2024 I called AAA on Monday and had my car toward to hyundai service. They gave me a $199.95 bill for finding the problem with my car. And they said they would contact me and let me know about the problem with my car in 3~4 days. I am an Uber driver, but I am currently unable to work because I don't have a car.

We keep getting an engine light every 2-3weeks. That sets the engine in a safe mode (limp mode). The code comes up Knock sensor overheat. Tho inspecting the engine we have notice in that time frame the car is low 1-2qts oil. Once the oil has either been replaced or added to and code reset it drives normal. Again until 2-3 weeks and bam. A course now we know to check our oil. After hours of research, we see no recalls for our car. Tho many years back that have had the exact same issue. The issues also came to light when car hit around 80k miles.

The hybrid power system has stopped all together twice while driving once back in May 2021 and again in December 2022, the car has just under 50,000 miles. Both times this has happened the car was actively being driven, and has caused us to pull over on the side of the highway because there is no warning beforehand, everything from the power steering to the gas goes out. It-??s terrifying and unsafe for anyone in the car but also near it when it happens.

There is excessive oil consumption with the engine in my car. Hyundai says 1qt per 1000 miles is -??acceptable-?? however this is not acceptable and can lead to catastrophic engine failure and oil slick on roadways if not caught in time. This is a know problem with Hyundai/Kia at this time. In many cases Hyundai/Kia owners are left with a -??lemon-?? of a new car that is currently in warranty. Some have been granted replacement engines that have not lasted 3000 miles. A recall must be issued in the name of safety on these cars. The manufacturer must be held accountable for the lack of quality that has been put out over the last decade.

I bought this car 1 year and 2 months ago from a Hyundai dealership. The car was close to 73,000 miles. A few days after I got the car I started hearing this noise that sounded like a rattle coming from the front while accelerating to about 2,000 RPM. Due to my work, I went back to the dealer after 1,000 miles and explained to them about the noise and they duplicate it. The engine was consuming oil when I bought the car, I went back to the dealer and never did any testing on oil consumption. The problem got worst and worst. I started a claim with Hyundai Corp and I waited for 4 months to the an approval and they are only covering 50% of the engine. Dealer says I have to pay $3,200 to start engine replacement process, with no payment plan. Now I have a debt of $17k and no car. Engine has no compression on cylinder 3, which causes a misfire and makes the car unsafe to drive and leaves me unemployed with a child and bills to take care of. Thank you Hyundai, nice job ??'??.

After a year of issues, burning oil, changing spark plugs, my engine is dead. Hyundai has ignored issues and many times refused to pay for oil, parts, etc passing all costs to me. I have a loan of 15k and no car. Called and emailed their case management team-?"no help, no reimbursements. I have no equity-No property left. This was my only mode of transportation. Due to their slowness, I had to buy a new car and spend money I was not scheduled to spend. The financial stress and lack safety and unprofessional manner from Hyundai is at a new level-ridiculous.

The contact owns a 2019 Hyundai Sonata. The contact stated that while driving at approximately 70 MPH, the vehicle inadvertently revved and decelerated to 40 MPH while the accelerator pedal was depressed. The check engine warning light was illuminated. The vehicle was towed to the dealer where it was diagnosed that timing chain had failed and the engine needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact stated that while driving at undisclosed speeds, the check engine warning light illuminated. The contact then stated that occasionally she needed to add engine oil between oil changes. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and a case number was provided. The failure mileage was approximately 220,000.

Car consumes excessive oil -?" one quart about every 500-700 miles. This has caused sludge in the engine and the car hesitates significantly on starting from a stopped position and now hesitates even at highway speeds. This has become a definite safety issue. If the car stalls it is only a matter of time before I am hit by another driver. The dealer first stated the oil consumption was fine IF it was one quart every 1,000 miles and that no repairs would be needed. My car is consuming almost double that amount of oil. Dealership agreed to look at it; stated the car needs a new engine. Hyundai refused to even do an oil consumption test, let alone repair/replace the engine. The -??sludge-?? in the oil that Hyundai states was present is a result of the oil consumption (even the dealer service department verbally agreed). I-??m literally putting new oil in it about once a week! There is no possibility this would NOT cause sludge. In addition, dealership said to expect the engine to fail fairly soon. Hyundai claims the car was not maintained properly; however, that is untrue. I-??ve submitted records to them that I had. The warranty has no requirement that the oil must be changed or maintained by a certain individual or company. Without a new engine, the car will continue to hesitate and will eventually fail. Hesitation (and especially engine failure) subjects me to a much higher possibility of a crash causing injury or death to myself or someone else. Hyunadai should absolutely recall the thousands of vehicles having this exact same issue.

The contact owns a 2019 Hyundai Sonata. The contact stated that oil was leaking onto the ground from underneath the vehicle. The vehicle was taken to an independent mechanic and stated that the drain plug needed to be replaced. The drain plug was replaced but the failure recurred almost immediately. The vehicle was taken to the dealer and the contact was informed that the oil pan was fractured and needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, and a case was filed. No additional assistance was provided. The failure mileage was 49,000.

I noticed the problem when my change oil light started coming on several thousands miles before my oil change was due. I checked the oil and it was very very low. Much lower that it should have been at that point during the maintenance period. We added oil thinking maybe something had happened with the previous oil change. Made it to the next round of maintenance and a few thousand miles into that one, same thing. Oil light came on again. Extremely low oil levels. I called the dealership where I had purchased the car - I am the original owner - and they requested me to bring it in for an oil consumption test. It was an immediate request. No other questions were asked. After the dealership kept my car for 2 1/2 weeks we get a call that the "valve" was full of "oil sludge" and were accused of "maintenance neglect", although we can produce records, and due to that Hyundai Corporate said our warranty would not cover it and repairs will not be covered. We would be held financially responsible for a brand new engine. I declined the repair as we cannot afford the repairs at this time and told the dealership we will continue to monitor oil levels.

A hairline crack from the engine oil drain plug causing leaking oil. This is a very common issue for this engine. Mine was present when the car was new. My local dealer claimed my car has run over something, which never happened. No dent or damages on the oil pan, just crack on the side of pan. This is very common issue for this engine. Low engine oil level will cause engine failure.

The engine is burning the oil faster than normal. There are no oil leaks. Called the dealership and they said it-??s an oil consumption. I got an oil change March 3,2023 and my oil pressure light came on last Friday April 14,2023 as I was driving I pulled over and there was completely no oil in the car. The dealership told me to top it off until they can look it at. I topped it off Friday with two quarts of oil that I purchased from auto zone. I checked my oil again on Yesterday April 18,2023 and the two quarts of oil I put in was completely black

Well below the 5000-mile mark for an oil change, multiple times between multiple oil changes my oil light would come on. I would be at a stop light and the oil light would come on as soon as I start going again. Checked the oil when I got home and there was barely any oil on the stick. Found hundreds if not thousands of complaints about the engine burning oil very fast in multiple Hyundai's and Kia's for almost a 10-year span. This has yet to be recalled by Hyundai, this is a very dangerous situation that if it continues going unnoticed, could cause death or serious injury. It is a known issue at Hyundai dealerships, and they will fix it if it's still under the 100,000-mile warranty, but only if you bring it up to them. Hyundai/Kia has yet to fix the problem or do a recall that has been across multiple models for 10 years.

The car was stolen, one of the vehicles that Hyundai manufactured without an Engine Immobilizer, making it very easy to steal. Consumers didn't know about this defect, because the corrupt automaker kept us in the dark. I'm fairly certain that by breaking the steering column to expose the port to start the car, that driving the speed limit or having control of the vehicle was on the thieves mind. The safety of my neighbors and anyone they were driving would have had their safety compromised. The vehicle is currently being repaired cosmetically. The Engine Immobilizer will not be installed by the body shop. It was inspected by a certified repair shop of State Farm. No warning lights were illuminated.

I was traveling on a highway when a "hybrid system warning" suddenly appeared on the dashboard. Every dashboard warning light illuminated. The car began to lose power. I exited the highway immediately and the car began to have sporadic power and was "lurching." I immediately pulled onto the shoulder and at that time another warning on the dash appeared within a minute or two of the first warning that said "shut engine off." The computer screen began to flash on and of and the windows would not roll up smoothly. When the tow truck arrived the car wouldn't start and it didn't recognize the key fob. Hyundai now has the vehicle and claims the car needed a "software update", but they cannot tell me if it will ever happen again and cannot tell me why the car goes into critical failure when it needs a mere software update. This is the second time this has happened. The first time it was repaired under a voluntary recall campaign about a year ago. This is an extremely dangerous occurrence as the car loses power without warning. I was fortunate to be near an exit when it happened and able to safely get off the highway, but that was just luck. The manual indicates that a hybrid system warning means that the car can potentially go on fire.
