ENGINE
3 months after the engine was replaced under extended manufacturer warranty the vehicle started shifting funny, took it to the dealership and was told the transmission was bad, then another person in service said the transmission wasn't bad and didn't need to be replaced and they couldn't find anything wrong (after waiting for 2+ weeks for the transmission to come in), then the car left us stranded on the side of the road and not running, took it back to the dealership and was told it's a bad catalytic converter and we had to pay $2000+ to replace it. They at this time blamed the engine issues on a bad alternator. Now the car has a check engine light again and is throwing the code permanently for the catalytic converter. No way that a HYBRID car that barely ever actually runs on the engine should need a new calaytic converter around the 100,000 mile point except for an engine malfunction, which was the case and that engine was replaced back in December. Hyundai says it's not related and sorry, you have to pay for everything.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
Since a few weeks after buying the car new, the battery dies and self resets every few weeks on average. No error codes occur, but the car had clearly lost power while parked, indicating an issue with power management. For the last could months, car now has 26-27K miles and is 21-23 months old, it had mostly stopped resetting. It now is dead when I go out to it, even after only a couple hours of it being parked at night or during the day. I have to manually access the car and use the battery reset button. They observe no error codes. I have read other people have the failure while driving and fear and electrical issue could be a fire hazard. At the very least, it is a personal safety issue in making me take time to access my car, which could increase my risk of being attacked while trying to get into my car safely. It has occurred 5 or 6 times since August 21, most recently on October 8th and 9th.

I have a 2021 Hyundai Sonata SEL with a Smartstream 2.5L engine w/ GDI & MPI. I have have always heard a loud knocking noise coming from my engine since I got the vehicle when in park. When you are accelerating it hesitates and you can hear a knocking noise. I have taken it to the dealership multiple times and they were able to feel and hear what I was talking about but ensured me it was fine. Recently it has been a lot worse. On 10/18/2023 I was getting on to the highway from the feeder. I tried to accelerate to about 50 mph and I heard the same knocking noise and my rpms jumped all the way to the top. Then my car suddenly stopped getting on to the highway. It took it about a minute before I could start driving again. Luckily there was no one behind me because it could've been really bad. I got home and looked under the hood and it looked like oil had sprayed out of the engine. You could to see oil splatter on the fender. No one was hurt thankfully. I have been complaining about the knocking and hesitation while accelerating for almost 2yrs.

ELECTRICAL SYSTEM, LANE DEPARTURE: ASSIST, LANE DEPARTURE: BLIND SPOT DETECTION
As I was driving my dashboard lit up with warning lights and audible alarms indicating that I should inspect my regen brake. Safety features such as lane departure, lane assist, blind spot indicator stopped functioning and my speedometer did not work. I stopped the car and looked behind the front wheels and nothing looked “unusual”. I restarted the car and all of the alarms went off again, leaving me without a speedometer or the safety features mentioned above. I scheduled an appointment with my dealership explaining what had happened. They did a diagnostic test and determined that it was a faulty E Brake Module that needed to be replaced but is on back order with no parts available in the US to order. Furthermore they do not know when a replacement is available. They reset the sensors so that my safety features were restored. This is the second time within a 14 months of purchasing the brand new vehicle that electrical systems have needed to be replaced. The first time was a faulty wiring harness located in the trunk area that the dealership had said “must have been damaged during installation at the factory”. Again-when I driving at highway speeds suddenly the alarms and warning lights were triggered-leaving me without the same safety features, speedometer and power steering/brakes. The dealership was able to replace the wiring harness and the problem seemed to be resolved until this latest incident.

UNKNOWN OR OTHER
For now the fifth time in the last 16 months the HEV light and engine light has lit up while the car jerks and sputters and dies. Below is the incident report that I filed on or about August 8, 2022. Again at the end of the day yesterday on October 20, 2023 the same issues still arise for the fifth time. See below for a re-cap of the issues I am once again experiencing after Hyundai claims to have fixed the issues: 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.

Insurance companies are not proving insurance because of rise in theft of Hyundai vehicle. Now they are asking to install remote start kit for physical engine immobilizer. Cost of this installation is $350 - $500, Hyundai is not entertaining this issue. Hyundai are saying we have done anti theft software update but insurance companies are saying that is not enough.

SERVICE BRAKES
The left front brake caliper fell off and rubbed on the wheel’s rim. When I drove in reverse and hit the brakes the wheel would lock up and I couldn’t move. The dealer replaced the caliper. I had the brakes inspected by the local tire and brake specialists, Les Schwab. They wrote the inspection as the brakes locking bolt(the bolt that holds the caliper in place) was missing and the caliper was rubbing against the wheel. There wasn’t a warning. But, I did hear a loud clunk right before the brakes failed then the brakes made a rumbling sound as if I had a rock stuck in the brake pad. I asked the dealer to save the broken unit so I could document it but the service department manager for Korum Hyundai of Puyallup tried to pass off a different unit. I took pictures of both my unit (on the car) and the unit the manager was trying to pass off.

Engine began having issues with stalling out around 70k Miles. Car was taken to the dealer and Tessa on for issue couldn’t be diagnosed. Car then began again at 83k miles took it to a repair shop and the issue could not be pin pointed once again. I was informed that the engine would have to completely fail for the issue to be properly diagnosed. Engine completely failed at 100k miles from barring breaking while I was driving the vehicle with my children in the car. Vehicle had to be towed to a mechanic shop and later transferred to Hyundai of Cumming. This issue was then confirmed for engine failure due to barrings breaks and the oil not circulating through the engine. There were not any prior warnings signs such as a light on dashboard or smoke out of the exhaust. All car maintenance is documented and up to date. This is the same reasoning behind prior 2016 models failing and being recalled. Dealer is refusing to issue a goodwill repair that was recommended by Hyundai corporate.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, POWER TRAIN
I am having electrical issues with my 2016 Hyundai Sonata plus the other recalls. It started as issues with the lights on the driver side. I have replaced several bulbs and the entire light even and still have issues with the lights working properly. Now the issue is the battery, alternator or the starter. The starter had to be replaced as I was advised by Hyundai dealership when my engine had to be replaced, per recall. I had to purchase a starter, that was three times the amount at the dealership because the one that is manufactured in the auto stores is not correct, so it should not be the starter as it is only 1 to 2 years old. I have had the alternator replaced as well as 2 batteries and I’m still having issues. It cut off completely while driving on more than 1 occasion. There was no warning, no power steering, gear lock, no lights & no power so I could not move and almost had a major accident. It is definitely a safety hazard even after the repairs, it has happened again! My vehicle is currently not working because the new battery will not hold a charge and they both have been replaced. I’ve been having other electronic type issues with this vehicle. My information center has not worked for the past 8 months or so! I reported this to Hyundai and they agreed that it could be a part of a previous recall, and advised me to go to the dealership to have it repaired. The dealership refuses because they don’t have required information to show it as a Current recall and want to charge me half the price of a new car to repair. I am not the only one experience this as my research has led me to several other Hyundai owners experiencing the same issues. It is not fair that they cannot be corrected as these are things that are none of consumer fault & should have been high demands to proper repair or recall being a major safety issue as it can cause a horrific accident! Shame on Hyundai for putting their Hyundai customers at risk & through so much chaos!

SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
My husband (Scott) was driving the car on Florida highway 408 eastbound approaching the exit 21 on 10/12/2023 around 8 am. Scott heard something pop suddenly and saw fire shooting out from both sides of the car in the rearview mirrors. Upon noticing the fire, he tried to slow down to pull over the car, but brakes failed (went to the floor). A police officer on the road happened to see the fire so he drove next to my husband's car and Scott yelled at officer that he had no brakes. The officer went ahead of Scott to help Scott's car slow down. When approaching uphill slopes by the exit, Scott was finally able to use the emergency brakes to come to a complete stop. The fire engine came right away and put out the fire which took over 20 minutes. My husband is handicapped and him walking away from such car catastrophic fire unharmed was near miracle. Two weeks before the fire, I happened to take the car in for checkup at Greenway Hyundai Orlando and the 2.5 hour inspection found nothing wrong with my car. I wanted my car checked because my car stalled briefly pulling out of a parking space a few days earlier.

ELECTRICAL SYSTEM
When I am driving with my headlights on auto, every time I use my turn signal (and sometimes spontaneously) my headlights flicker. Sometimes it’s just for a second, but other times it has lasted more than 3 seconds which can be very dangerous while driving at night. It is also dangerous because other drivers may think I’m flashing my brights at them when im not. During this the dash will flicker as well. This has been happening since I got the car in 2018 so it’s not a battery issue.
