ENGINE
On February 27, 2023 we went to the Hyundai Dealer because our engine was leaking oil and we were told by Pep Boys that the Rear Main Seal was leaking. The Dealership scheduled us a service appointment three wks later, on March 23, 2023, when they replaced the valve cover gasket and the high pressure fuel pump gasket. On Jul 15, 2023, 2.5 months later, we return to dealership because our engine was leaking oil again and had leaked into the spark plugs tubes. They replaced the valve cover gasket again. Two weeks later on July 28, 2023, we went to the Dealership because the engine light turned on and the engine was misfiring while driving. They did nothing but added 3 quarts of oil because our oil was low despite us changing our oil 1 month prior (June 28, 2023). On September 25th, we returned to the dealership because our engine light turned on and our engine was violently shaking while making noise. At this point, we were frustrated and did not feel safe driving the car. We pleaded with the Service Manager to replace the engine from all the issues we have been experiencing including having to constantly add oil or change oil every 2.5 months. They held on to our car for 1 wk and gave us a rental. After inspecting our vehicle they replied that there was no engine issue detected so the Manufacturer will not replace the engine under the warranty. They only replaced the spark plugs and charged us with the service, parts & rental costs. It is now Monday, Dec 18, 2023, 1 wk before Christmas, and our engine light turned on once again while driving with our toddler in the vehicle. The engine not only misfired but did not allow us to accelerate beyond 30mph during high traffic hours on a road with a 50mph limit. The next service appointment available is 10 dys away, Dec 28, 2023, and they are asking us ~$400 to service the car. We feel helpless with the dealership/manufacturer, they are refusing to replace the engine. We fear that they are waiting for the warranty to expire.

ENGINE
First time I took my vehicle to the shop for over consuming oil they replaced the oil and cleaned all the parts. A few months after this my car would not accelerate properly and had a loud knocking noise in the engine and check engine light came on. After taking it to the dealer I was told I would need to replace the whole engine. I have proof of proper care done on the car but since I am second owner it is not covered in the original warranty. My car could have stalled and resulted in me and my family injured at the least. Hyundai knows about these issues and needs to recall the engines.

The contact owns a 2017 Hyundai Sonata Hybrid. The contact stated that after his daughter started the vehicle, the vehicle began to knock and shake violently, and his daughter smelled a burning odor within the interior of the vehicle. No warning lights were illuminated. The vehicle was towed to the dealer, who determined that the connecting rod bearings inside the engine had worn prematurely, requiring the replacement of the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V727000 (Engine), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was unknown.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM, ENGINE
The vehicle has twice been disabled while driving due to “lost communication with hybrid module powertrain control module.” This breakdown is a significant safety hazard as the car loses power and coasts to a stop without any warning. The second time was on a 65 mph highway. Neither time has had any warning before the malfunction lights appeared. The first time occurred on 10/7, and the vehicle was towed to the dealership. Nothing was done besides clearing the trouble codes and test driving with the car, which returned at the end of October—the second time the breakdown occurred about a month later on 12/3. This second time, I removed the code myself on the roadside so as not to be in more danger, and I am currently awaiting an update from the dealership’s service department on their next steps after initially being told to just have it towed in again. Losing power without notice is incredibly concerning. I want to report this safety issue and determine my next steps to resolve it, as this has dramatically impacted my trust in the vehicle and its safety.

I have a 2017 Hyundai Sonata I bought brand new. My car started burning oil where I was having to put oil every time I put gas which is weekly. I did the oil consumption test where I drove it 1000 miles 3 times and it burned 1.75qts, 2 qts, and 2.75 qts. They are saying it needs a new engine.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
In May, the engine completely failed as I was driving on the freeway, without cause. It had to be towed to the dealership where luckily the engine was replaced under warranty. Less than 6 months later, the HEV and CEL warning lights came on as I was commuting to work via highway. The car was very low powered, hard to accelerate, and immediately decelerated whenever I started to let off the gas pedal. It struggled to go at or above 60-65 mph. The freeway speed was 70 mph and it was a safety risk for the car to power down. Dublin Hyundai could not replicate the problem, simply recharged the battery and said I was good to go. Less than 1 week later, the exact same thing happened as I started on a road trip. I had to return the car home and get it towed to Stockton Hyundai for diagnosis. This is car is only 6 years old, has been routinely maintained, and just hit 100k miles, for which Hyundai is denying any repair assistance even though there is a lifetime hybrid battery warranty.

ENGINE
About a year ago during an extended freeway drive I noticed my engine started to sound different. I checked the oil and found it was a quart low which had never happened before. I filled the oil to its proper level and continued driving. About 100 miles later I decided to check the oil again and found it had used about 1/4 quart. Later my check engine light came on and it showed a code related to failed exhaust sensors. Since then I have had to check and fill the oil every 100 miles or so and now carry 5 quarts of oil in the trunk. I also noticed that my exhaust leaves an oil mark on the ground if I leave the engine running for a couple of minutes. I checked for oil leaks and didn't find any. My miles per gallon reading is also down. Seems to use most oil during freeway driving. I worry the engine could fail at any time and have been forced to restrict my driving to short local trips. I had the knock sensor installed per Hyundai's recall. Hyundai refuses to cover an oil consumption test.

My Hyundai engine is burning through oil like crazy. Only at 84,000 miles, and everytime I get my oil changed (every 3,000) it is completely dry. This is a known problem with Hyundai, and there needs to be a recall on these vehicles. It is costing me a fortune, and the risk of having my engine fail/catch on fire is not something I want to be worried about everytime I drive my vehicle. Something needs to happen to get this issue resolved.

Was serviced by Hyundai in March 2023 to for oil sensor light but was really the oil was being burnt inside the engine Hyundai ran 2 oil consumption test in May 2023 and June 2023 which the car failed both. Service manger sent paperwork to Hyundai letting them know that engine was faulty because paperwork was summited with the wrong mileage the replacement of the engine has not happen. So Service manger has asked me to continue driving 1k miles and checking if engine is still burning oil which it still is I continue to write the service manger and sending pictures I can not drop my car off because we only have one car and they rarely have loaners and we are in bankruptcy so renting a car with a debt card is expensive trying to let people aware that this is a problem that Hyundai knows they have on these Sonata since 2015

STEERING
I have been having issues with the Power Steering, I often get the wheel sensor and stability sensors activate making it very hard to steer my vehicle, I have taken to the repair shop to unlock, but comes back after a week. this is a problem and feel very unsafe driving as it has locked while I am driving, having me to pull over to turn off my car to clear the sensors. this issue has been happening more often, and has become a financial burden as the dealer charges a fee for running analysis on the vehicle.

STEERING
Steering wheel froze/would not turn, and Shift selector and Ignition key were also frozen on Three occasions. Once while backing out of parking space, and Twice after being parked. Vehicle is available for inspection. Frozen steering wheel while in motion could have caused accident. Car was inspected by Dealership, but Service Representative stated " could Not determine problem unless it was happening at time of their inspection" and " they are having this problem on other Hyundai models." Only inspected by original Dealership. No prior warning to any of the three incidents.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
Engine Shut Off Without Warning problem of the 2017 Hyundai Sonata Hybrid While driving the car on the freeway, it will jerk forward and then shortly after lose power. I pull over (luckily haven't been killed yet) on the side of the freeway. I've taken my car to a Hyundai dealership third times. All Three time I was stranded on a busy california highway. I have looked into this warning over a year and no one seems to know the problem. This should be a recall and all Hyundai dealers should be made aware of what this warning is. We as Hyundai owners need answers and help.

ENGINE
Engine has a serious oil consumption problem. The engine has consumed 12 qts last 5,000 miles, or roughly burning 4 qts per 1,500 miles! Twice already it has rendered the engine dry despite frequent oil checks. Car also has routine oil changes every 3-5,000 miles. The safety concern is that the engine seizes in the middle of traffic. Also, because of the rapid nature of oil consumption, it requires travelling with emergency oil replacement supplies within the cabin. Fear is a collusion in the back (especially if stalled!) that could result in a fire, fueled by the supply of oil in the car. We keep at least a gallon (4 quarts), more if we are travelling anywhere more than an hour. We are a one car family and the safety issue is real. This is an ongoing problem since at least April of this year. Engine needs replacement.

AIR BAGS, ELECTRICAL SYSTEM
1) I purchased 2017 Hyundai Sonata Hybrid new. Now for 2nd time, trunk latch won't open trunk. 1st time i paid for a new park on the trunk. Now again, trunk won't open. Dealer states they have to replace rear bumper antenna. 2) Airbag light came on on the dash, and remains on when I start car. Dealer stated it is the driver seatbelt light. I Never had an accident with this vehicle and air bag(s) have never inflated. Dealer stated they will have to replace driver airbag which will cost me $1,436.35. I don't know why I have to pay for a new driver airbag when I bought the car new and never had an accident with the car.

STEERING
Steering has locked up on me, usually when coming out of a parking space. Makes a clunking noise at times when turning. Only way to reset is to turn engine off and on again. Has been giving me trouble for a number of months now. Had 2 different Auto Repair services look at it, and they say it may be electrical or something more serious. Both recommend to take it to Hyundai dealership where I got it. I am awaiting a service call from the Hyundai dealership, and from all these other reports, I think the cost of the repair should be covered under a recall. Very unsettling to drive when the steering does not work properly.
