The engine is burning oil. Oil level drops by 3-4 quarts every 1,500 miles.
- Santa Clarita, CA, USA
I was stopped at a red light and when it turned green, I began to accelerate. The car stuttered and the check engine light was blinking. I pulled over and had Autozone run the code. The code is P1326, engine knock sensor. It was put into limp mode and it shook pretty bad in lower gears while accelerating. I had to pull over and let several cars pass me as I couldn't go above 2,000 RPMs. When I got home, I called roadside assistance and had it towed to the nearest dealership. That was this morning (5-4-2022). I just purchased this car used in the beginning of March. I don't have all the records since I just purchased the vehicle used. I just changed the oil last week.

Same problem with this 2018 Hyundai Sonata Limited Hybrid engine as the already recalled 2017 Sonata-€™s with the same 4 liter/direct fuel injection engines. At approximately 69,000 miles the problems and check engine light analyzed was done by Auto Zone and Brandon Hyundai (3 times each and finding additional problems each time). I have documentation. P1326 Knock Sensor indicated engine failure problems P0302 Cylinder 2 misfire (occurred next day after repair of this part) U0293 Lost communication with HEV Powertrain control module ( not charging hybrid U1004 H-CAN C135B-08 no code explanation given C1612-08 CAN time-out TCM C1611-08 CAN time-out EPS ECM C1614-08 CAN time-out HCU C2229-08 Towed to dealer for repair. These problems occurred from 4/18/22 to 4/27/22 3 times in less than 2 weeks. car still in service dept today 4/30/22 with no resolution. Failures continued to escalate after each service. Went into -€œLimp Home Mode-€ twice. Very unsafe to drive. Stalled, jerked and speed reduced. This happened on I-75 twice and once on Hwy 674. Felt in danger each time (especially the last time on 4/27/22). Turned on caution lights and tried to safely pull over. Check engine light blinking and many other engine lights came on. Brandon Hyundai said engine may need to be replaced, but then they want apply -€œbandaid temporary fixes-€: like replace Cylinders again and now Knock Sensor; instead of addressing safety issues of a failing engine. These engines are unsafe! They need to be recalled and replaced before they could causing major accidents due to engines poor performance as it-€™s failing. The jerking and stalling put me in danger prior to being able to restart the engine to get off the road. Are these a possible fire hazard as well? I-€™m scared to drive it, whenever I get it back from the dealers service department!

The contact owns a 2018 Hyundai Sonata. The contact stated that after filling the engine with oil, approximately 2 months later it was discovered the engine oil level was extremely low. The contact indicated that the engine oil was being consumed at a very rapid pace. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure. The failure mileage was 65,000. Consumer stated it was determined it was a valve cover gasket not pistons as a previous mechanic stated. So no need for recall.

2018 Hyundai Sonata sport. Purchased vehicle 03/20/2021 and it has been in the shop 5 times for the same issue. Car starts to smoke and make a loud knocking noise, when checking the oil, it appears to have no oil in the engine at all. Every single time they have changed the oil and replaced it and within a 1,000 miles the oil has completely dissolved in the engine. They performed a consumption test and stated that they did a top engine cleaning for the combustion and that it should not happen again and if it did that they would reach out to Hyundai to start the process of replacing the engine. Took it back at the 1,000 mile mark and they stated that it was fine, but after only a few weeks to a month the car started smoking and knocking again, took it back and yes the engine was bone dry again no oil at all on the dipstick. This vehicle has been in the shop more than I was able to drive it. The oil light keeps jumping on and off and the dealer is aware of this issue and they stated that the manufacturer is aware of this issue as well. But it seems that they are refusing to rectify the issue with a new engine and just keep patching the problem, that I would have to keep taking back every 1,00 miles for a consumption test. The oil ight was present when they sold me the vehicle but the dealership stated that they had performed an oil change and it needed to be reprogrammed but that did not fix the problem.

The oil consumption is out of control for their vehicles I've had more oil changes that I've ever done on a vehicle I've done oil construction tests and they always say it's just at the 1 quart that they allow who's is bull I've checked my oil cold and it's hardly on the stick and the oil light has come on numerous times I'm no genus but I do know it's more than a quart low when your oil light comes on. At 1,100 miles it was 2.5 quarts low and I was forced to do another oil change when I only had 1,100 miles on this one. The first pic I've attached is cold oil level at 1,100 miles after oil change. The car only has 53K on it and I want to know how many times do we have to do oil consumption tests to get it fixed under the lifetime engine replacement and forget about the roadside assistance from Hyundai they tow 20 miles that's it and the rest is on you how is that fair when it's not your problem to begin with.

I was driving began my Sonata in moderate to heavy traffic.without warning the vehicle began lurching. I was unable to control it. The Hyundai had a mind of its own. I got the "check engine" light on & some message on the screen that I could not read because I was driving. I pulled off the road & had the car towed to a Hyundai dealer. Upon return of the car, the dealer explained that Hyundai took control of the car as a "safety precaution" for the engine. This is an unsafe safety precaution. They not I controlled the car.

While driving car on an interstate highway engine power suddenly declined and vehicle had no pickup. I was unable to keep up with the highway traffic, I had to tow the car to the dealership for repairs. I was informed by the Hyundai service department that my car required a computer software upgrade to correct the condition. Apparently they are aware of this problem but there are no recalls concerning this problem.

I was driving in another city and my car went into limp mode. I had it towed to nearby dealer and they said I was low in oil, after having it changed an month before. They did oil consumption test and found it to be 1 quart per 1000 miles and left there and 2 months later had another consumption test done after seeing my car was one in the class action on engine and bearings. They found this one to be 1.1 qts per 1000 miles. Dealer said no way will they send info to get a new engine under warranty. A qt a 1000 miles seems very excessive. Dealer said that you need to be at 1.5 qt per 1000 which would be almost no oil when I go have an oil change. The vehicle is only 3 years old and 100000 miles. This seems like too much oil to be burnt. And they know they have engine issues and will not rectify

In Feb 2020 my Sonata went into safe mode after exiting highway and dealer ended up replacing "knock sensor". in December 2020 my engine "stuttered" throwing me forward as if I had hit brakes hard. No warning lights or messages occurred and after a few seconds car acted normally mostly. A few days later after exiting highway again the engine warning light (orange) came on along with error message "possible condition with engine control system" has been detected. Car did not go into "safe mode" and seemed to be operating normally. I contacted dealer who assured me safe to drive over hundred miles back to dealership in this condition to check. I drove back from East coast fl to West coast fl to turn car in. I believe engine issue experienced is related to the theta engine issue and repair would be covered under settlement. Dealership disagrees and has indicated issue is with fuel pumps (both are being replaced) and charging me $2300.

Everytime I accelerate my SUV makes a very loud grinding / ? noises and sometimes when I slow from accelerating. Talked with Hyundai mechanic that said their may be a engine problem. Only had it 1 month. I am afraid that it will become very dangerous to drive it.
- Mooresville, NC, USA
I was driving my car at about 45mph on my way to work on a highway road and out of no where it jerked and the check engine light started flashing. Car would not accelerate above 2,000 rpms. When the car jerked, it was so sudden it injured my lower back. My back has been very sore since this incident. I then took to dealer and they said it was a known issue and Hyundai had not recalled my specific car. Dealer was able to replicate the issue. The cleared the check engine light and sent me on my way. One mile down the road exact same thing happened. Car is currently at their shop with no eta of repair.
