ENGINE, UNKNOWN OR OTHER
For the fourth time the HEV light (and others) has come on and the dash has lit up while I was driving, with the last three times leaving us stranded in dangerous road situations with little or no power. The light first came on in July 2020 at 40,089 miles. A dealership reset the codes and I had no problems until June 7, 2022 when the lights lit up on the dash again and the car died and I had to have it towed to a local dealership. They could find nothing wrong with it and checked all the wiring and said none of the codes were coming up and that the car ran fine for them when test driving a day or two after I had it towed. So they released the car back to me deeming it good to go. Then only 19 days later on June 26, 2022 the HEV light among other lit up again and the dash indicated to pull over and cut the car off due to the hybrid system. I had it towed to the nearest dealership again. The then looked at it and said they reset all the codes and everything looked to be good to go. Then AGAIN on Aug 8, 2022 (3rd time in two months), we were put in a dangerous situation trying to get the car off a busy highway when the HEV light (and others) again lit up the dash and our power went almost completely out while the engine jerked violently as we tried to avoid being hit by cars while trying to get off the highway before it completely died on us. Four times now Hyundai dealers have shrugged this off saying "we reset the codes" and we can't find an issue. We have been put in dangerous traffic conditions three of these times.

ENGINE
The issue that I am having with my 2018 Hyundai Sonata is excessive oil consumption. And yes the vehicle is available for inspection. My family and I are put at risk because of the high oil consumption the engine may seize at any time. I have been told that not only is the engine is at risk but also the exhaust system due to the possibility of oil build up there also causing safety issues. The Sonata has been put through an oil consumption test by a local Hyundai dealership. This consists of changing the oil and then at 1000 mile intervals up to 3000 miles the oil level is checked by a dealer mechanic to check for oil loss. During this 1st test period one check had a loss of 3/4 of a quart and another was 1 3/4 of a quart. After this 1st series of tests there was a complete engine cleaning to remove all built-up oil residue within the engine followed the checking of oil levels again every 1000 miles 3 times. Again, oil losses varied from 1 quart to a 1/2 quart loss. I was assigned a case manager to monitor these tests. At the completion of the testing, after 4 weeks of hearing nothing from my case manager even though I had left multiple messages, he called and said that these results were considered normal by Hyundai. Again, all tests were completed by a authorized Hyundai dealership. There were no warning lights or messages but I did hear a slight knocking noise within the engine. I checked the oil on a regular basis after that and noticed the continued loss of oil. The was no smoke coming from the exhaust or no noticeable signs of oil loss on the engine or my garage floor. Although Hyundai recommends oil changes every 7500 miles I had oil changes every 3000 to 4000 miles by my Hyundai dealer. No one else. I also spoke to mechanics other than Hyundai and was told that there was an ongoing problem with Hyundai engines for oil loss. That is why I initiated the oil consumption test with my dealership.

STEERING
I was driving and tried to make a turn when the steering wheel gave out on me unexpectedly. This lead my car to continue forward onto the other lane of oncoming traffic. The steering wheel signal also turned on. When my car was finally able to turn and I arrived at my destination, I parked my car for 2 hrs. After it was time to leave the battery then died. I was unable to use the key or inside button to open my trunk, and had to wait for assistance. I believe these two issues correlate with the electrical power steering.

ENGINE, UNKNOWN OR OTHER
On the way home from the produce store today, the engine seemed to stall or seize while I was driving and the car reacted in a jerky manner. I kept going, as I was close to home, but could only travel about 20 mph, and it would periodically feel as if it were about to conk out. Check engine light came on at this point. Made it home, but no longer feel safe driving it. Am online now, searching for what to do. What I experienced sounds like the engine recall problem others have experienced, although my 2018 Hyundai Sonata is not on the recall list. Perhaps it should be.

UNKNOWN OR OTHER
Purchased a certified pre-owned 2018 Hyundai Sonata - found out recently the car is burning/losing oil- A few weeks after having an oil and filter change my oil warning light started flashing while driving.. Checked engine oil and could not believe that oil was almost empty.. Major concern is for major engine malfunction and possible locking up while driving- which could be fatal !!! Now I have to monitor oil levels/consumption every other day- I have contacted Hyundai and they're suggesting that I be without transportation while they take an undetermined amount of time to test the vehicle which is unacceptable !

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Driving on Interstate 10 westbound at about 0700. Clear day. No adjacent vehicles. The frontal crash avoidance alert suddenly went off and automated emergency braking activated as I approached an underpass. There were some slightly harsh shadows, but not the worst I have seen and I drive this segment every day. Entire event was very short. No injury or other event occurred.

POWER TRAIN, ENGINE, ELECTRICAL SYSTEM
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.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
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 “Limp 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 “bandaid 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 shark fin antenna assembly becomes dislodged from its base very easily and can fly off while driving or scraping ice off the roof with minimal force. Hyundai should do a better job attaching the outer shark fin plastic cover to its base.

STRUCTURE:BODY:DOOR:HANDLE:EXTERIOR
In August 2021, my son went to open the front passenger door of his 2018 Hyundai Sonata. When opening the door, the handle came off in his hand. We reported the broken handle and asked if it was covered under the factory warranty. We were told by the local Hyundai Dealer that it was not. So we paid over $100.00 to have the handle replaced. Fast forward to January of 2022, I was packing my son's car for him to return to college and the back passenger door handle came off in my hand. That's two door handles in less than five months. There was no forced entry. No yanking or pulling above a normal opening the door process. My son is unable to access the passenger side of his car and has to crawl across the back seat. When the front passenger handle fell off, the passenger front seat was unusable. I have done research online and this seems to be a problem. Our car is not the first one to have this happen. I placed a claim with Hyundai Motor America and was guaranteed a call back within 3-5 business days. I have since placed four more calls in to the customer service line and have yet to hear from anyone regarding fixing this issues. It has been over two weeks. I have photographs to upload but the system will not allow the upload although they meet all criteria.
