I am writing to bring to your attention a critical issue affecting my 2016 HYUNDAI SONATA 4 DOOR SEDAN, that warrants investigation and public awareness. Hyundai cars are currently plagued by ENGINE OIL CONSUMPTION PROBLEMS that ultimately lead to ENGINE FAILURE, due to there being NO WARNING LAMPS, MESSAGES, or OTHER SYMPTOMS OF THE PROBLEM PRIOR TO THE FAILURE. This is a concerning issue that remains largely unknown to most customers. When these issues arise, car owners such as myself, are often left with uncooperative dealerships that either deny the problem or offer minimal assistance. Even Hyundai corporate and extended warranties fail to provide adequate support, frequently citing owner negligence as a reason for denial. This occurs despite the fact that engine sludge buildup is inevitable, even with consistent car maintenance. Furthermore, I am forced to endure long waiting times for MY 2016 HYUNDAI SONATA 4 DOOR SEDAN, THAT HAS BEEN INSPECTED and, then DENIED FOR an ENGINE REPLACEMENT, and face additional months of delay for them to explain why. The situation is exacerbated by the lack of loaner vehicles and no assurance of rental reimbursement. This leaves countless individuals burdened with repair payments for stranded vehicles. My personal experience has been with Ourisman Hyundai, and many others have voiced similar grievances. Numerous complaints have been filed with the Better Business Bureau (BBB) and the National Highway Traffic Safety Administration (NHSTA), yet little action has been taken to aid the thousands of people who are experiencing the same problems to rectify this issue. It is imperative that ATTENTION is drawn to this matter as HYUNDAI'S approach to selling cars with HIDDEN ENGINE ISSUES PUTS CUSTOMERS AT SAFETY RISK AND places them in DIRE and DEADLY HARM. I implore all News Media outlets to conduct an investigation into these concerns and help shed light on a situation that demands immediate attention

found me driving on I 75 and I put the Cruise Control at 70 miles, instead of maintaining the speed at 70miles the vehicle accelerated to more than 90 miles per hour I had to quickly put my foot on the brake otherwise I could have an accident with the vehicle from the front, after all this happened, I felt the car was losing speed, I tried to accelerate but it did not go over 60 miles per hour. I took it to the mechanic and they did not detect anything in the vehicle's computer. This vehicle also turns off at times when you are driving and it turns off it also spend too much oil motor, I started looking for information on this model of car and I see that there are more than 550 people who have the same problem as me, this is an unsafe vehicle for the road

Hev warning turn off engine sign while driving on the interstate my car lost power and the car behind me had to suddenly move over this is very unsafe while driving down the interstate

This vehicle had a complete engine failure. Since it is a hybrid, when the engine shut down, the vehicle lost all power. The driver had no control over steering or brakes. The vehicle crashed through three trees and into a house. Hyundai Motors of America and NHTSA are aware of the issues with this vehicle's engine, however, this engine was already replaced. The problem was that the "limp mode" did not enact in this specific car. I brought this to Hyundai's attention at least 20 times and expressed my concern about the threat this vehicle posed to me and anyone else on the road, yet they continued to ignore me or attempt to rectify the issue. This vehicle was part of the class action lawsuit. I was told, after the seventh time the vehicle broke down (fourth time after engine replacement) that Hyundai would buy back the vehicle. That never happened. The vehicle shut down without "limp/safe mode", with an entire loss of power eight times and was brought into the dealership. Hyundai refused to help me. I knew it would end in disaster, and it did. I'm sure my vehicle is not the only one that does not have a safe mode taking effect when the power shuts off and there is no steering or brakes at 70 mph. I am using the date for the last time the vehicle shut off and the driver lost control and hit a house. However, there are eight other times this happened. I have more information and documentation if needed. I'm attaching my first claim, documents collected after that claim, the accident report (did not have photos attached, the photos are from the scene when I went there the next day), and all email conversations with Hyundai since the first engine failure. My big concern here is that even though Hyundai did try to repair the recall issues, they ignored everything else. I told them over and over that the limp mode did not work. This made it morally impossible for me to sell, even if I wanted to. They refused to help. I worry there may be others out there with this issue.

The airbag light is on, indicating that the airbox is not operating and will not go off in case of an accident. All steering wheel controls also don't work so it's impossible to adjust settings using the steering wheel or to enter cruise control at all. Previous years of this same vehicle had clock spring recalls and this appears to be the same problem so I wonder if the other recalls should be extended to this year vehicle? thanks

While driving on the highway at speed, I received a red Check Hybrid System error, and immediately lost all acceleration, putting myself and all occupants at risk on a busy interstate highway, as we tried to find a safe way to quickly change lanes and coast to a stop in a safe location. The cause is under diagnosis by a Hyundai Service Center. This was a sudden failure and there had been no previous warning alerting us to substandard system condition.

I had to replace the battery within a month of getting the car, then again 6 months later. The radio and back up camera went out after a year of having it. The headlights kept going out, and eventually the wiring started burning. Battery went out again along with the alternator now. Mid drive the lights would cut off, speed thermometer would be off by 15, and almost impossible to turn the wheel.

My right high beam stopped working, I have to add oil to my car every 3 days. Burns more gas going back and forth to work. Going around a fast highway curb, the engine shut down the speed of my car and would not stop dropping down to 45 mph in a 70mph packed highway. Awful experience. Called in the problem to Hyundai and they didn't show any care. I had an accident happen and I don't know if the electrical problem could be a result to the accidents. The case has been closed and nothing but a paper from a lawyer about getting $1000 for my car being at high risk. I have the case number available. It's been nearly a year.

I was on the highway driving and as I begin to accelerate the car felt as if it was about to stall out. When I came to a stop sign and made a complete stop as I accelerated to drive the car did the same thing as if it wanted to stall out. Now when I'm driving I can't go over 60 mph and any time I come to a complete stop and try to accelerate the car acts as if it wants to stall out so I have to take off slowly then take my foot off the gas pedal and put it back on as if is having trouble getting gas to the engine. I took it to my mechanic and it read code P 1326. Now my car is in safety mode

Hello I purchased a 2016 Hyundai Sonata 4/8/2020 with 110,743 miles on it with now 116,000. About a month ago my check engine light came on with no symptoms to the naked eye. Maybe a week later I could feel the difference in the speed control the air intake seemed very sluggish it won't take off from the line it will drag before it decides to pick up speed. Now the issue is that this is a common problem with these specific cars with no recall on them. This is an expensive fix that I should not be responsible for. Code P200 intake manifold.. it's not safe to drive a vehicle that you cannot control its initial speed...

Car shakes erratically when trying to accelerate and has no power after hitting accelerator. It struggles to get any power to get going after being stopped at a red light. Gear changes get stuck and I have literally been stuck in middle of intersection while doing a legal U-turn in a busy busy la intersection with my 10yr old in the back seat and the only way to get out of the situation was to turn car off and turn on again which poses a major safety issue for both my daughter and myself. Took car in to service last week and they supposedly fixed issue but one week later here we are with same problem. Service told me it looks like solenoid is going out. Which seems strange for a 2016 car with only 27,000. So if this was the case why not change it before it was sold to me. Also car had prior issues before it was sold to me according to service. I smell recall"??" I have no documentation but the dealer has all supporting paperwork.
