The problem has been reproduced while Accelerating to 40mph before car will Decelerate and only shifting between 1800-2000 rpm, on a busy road near my home, that may could have caused an incident

VEHICLE SPEED CONTROL
While driving on the interstate, the car suddenly stopped accelerating even though my foot was still pressing the accelerator. I took my foot off the gas pedal and let the car coast for a moment, though the deceleration seemed faster than normal coasting, almost as if the brake was slightly engaged. When I pressed the gas pedal again, it started to accelerate for a moment but then the same thing happened and it felt like the brake was engaging and the car was slowing down even though I was still pressing the gas pedal. So I took my foot off again and tried this process several more times, and in the meantime moved to the right lane and put my flashers on because I could not get the car to go more than 30 miles per hour and I was nearly hit several times. I was about to pull over when the issue seemed to resolve itself just as quickly as it had started. I called the dealership and they said because the car is not under any active recall, there's nothing they can do. This is a big safety issue! I was nearly run down by a truck! I just read that NHTSA has an active investigation for throttle issues, and that my 2011 Sonata is one of the affected vehicles. Please conclude your investigation and fix this issue before someone gets killed!

I know for a fact that one of the recalls I was told by Green Hyundai they could not do because they did not have a solution for the recall I know in 2019 I had the recall for my seatbelt done and it still comes on buckled I also know because I have one with blue Drive that if you hold the battery for the electric out without turning off blue drive it affects it I did not do this but somebody breaking into my car dead And I’m not sure all of the effects it had but I have had motor problems because the same dealer who told me they had no resolution for Yoru fact that there is no recalls that were undone even though are not done even though I was told that one they had no solution for and couldn’t do so I know at least one has not been done, also forgot to connect the coolant line resulting in motor damage..

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SERVICE BRAKES
I can’t drive my car in the dark. This has been on going since I bought the car and has just gotten worse. Everytime I turn my lights on all of my rear lights stop working and if I’m driving and the back light stop working my gas peddle also will not let me accelerate until I let my foot off and go back on to it but at this point I have no tail lights or brake lights.. I’ve tried so many things to fix this but this is a serious issue I had another friend who bought the same car and sold it a week later because of the same issue. I also can open my trunk and wiggle the wires and it’s a whole light show back there.

ENGINE
On March 5, 2020 I was entering a highway and increased my speed a little so I can get into my lane. After I made it into the highway my car lost power in the middle of the road and immediately would not go past 20 mph. I had to drive slowly and get all the way over into another lane and stopped in a nearby neighborhood. I went to not having any dashboard indicators to now a check engine light, oil light, and ABS. I checked my dip stick to see how much oil did I have in my car and I was completely empty but I was not due for an oil change yet. I had to get my car towed to my home. The next day, we tried to let my car rest so it sat. On that Morning, I drove my car maybe 8 minutes up the road to stop at an auto zone place. There weren’t any dashboard lights so I assumed my car was okay. The representative did a diagnostic on my car and he said he didn’t find any problems except I needed my brakes worked on & I didn’t have any oil. He put new oil in my car and told me I should be able to drive it up the road to my mechanic. I let my car run a little with the oil topped off and maybe drove no more than 15 minutes before those previous dashboard lights appeared on my car again and my car stopped power and wouldn’t drive any more than 20 mph. Long story short, I had to get my car towed twice since then. To my mechanic and then to the Hyundai dealership in Gaithersburg, MD. The rep. at the dealership said her mechanic recommended that I get an engine combustion cleaning, a new pcv valve and a oil change because I didn’t have any oil in my car. I told her that was weird because I had put oil in my car from the auto zone place and I believe my car must be leaking oil. Today, August 15th I am still having problems with running out of oil before my oil change mileage and date and I am not having any indicators on my dashboard to alert me. This can cause me to drive around without knowing and my engine can lock. That is a safety issue!!

I would like to report a serious Safety Hazard. Hyundai Motor America replaced my 2011 Sonata's defective engine in January 2020. The new engine turned off on its own approximately 20 times without the "Check Engine" light turning on between August 2021 and January 2022. The "Check Engine" light did not turn on until January 24, 2022. I had my car towed to El Cajon Hyundai in August 2021 after the engine turned off on its own while my car was traveling more than 40 MPH. El Cajon Hyundai could not diagnose the cause of the problem in August 2021 because the "Check Engine" light never turned on each time the engine turned off on its own. I had to work when the non-flashing “Check Engine” light finally turned for three days starting on January 24, 2021. The engine turned off on its own approximately 20 more times from January 27, 2021 until July 22, 2022 without the “Check Engine” light turning on. The “Check Engine” light finally turned on again on July 22, 2022, but it was not for Crankshaft Position Sensor. I told the mechanic what my Sonata has been doing since August 2021 after he initially could not diagnose the problem. The mechanic checked the computer again and he was able to locate the Check Engine Light message for the Crankshaft Position Sensor that occurred on January 24, 2022. I paid El Cajon Hyundai $593.71 on July 25, 2022 and July 29, 2022 to replace the Crankshaft Position Sensor. Unfortunately, my car turned off on its own again on July 30, 2022 and August 13, 2022 after the new Crankshaft Position Sensor was installed. My 2011 Hyundai Sonata has been posing a serious safety hazard for me each time I turn the engine on since early August 2021. Hyundai Motor America is ethically and financially responsible for ensuring that my 2011 Sonata is safe to drive. I am also concern that this serious safety hazard may be impacting other Hyundai owners.

ENGINE, UNKNOWN OR OTHER
My vehicle has an excessive oil consumption issue that started approximately in September 2021 after I got an oil change and had to put more oil in it after about 2 months when the oil change light went off. I have taken the vehicle to 2 different mechanics and they are unable to find an oil leak. There has been no oil leaking on the ground, no burning smell, no smoke showing, but the oil is somehow being consumed rapidly. The check oil light has not gone off since. I literally have to check the oil level every 2-3 weeks to check the levels. I got another oil change in February 2022 and have had to put 12 quarts in since that time. In July 2022 my car started driving funny with low power issues and the check engine light came on. I had the spark plugs and coil packs replaced. Now I'm dealing with low power on inclines and the catalytic converter now needs to be replaced. The mechanic believes it's due to the excessive oil consumption issue. It's my understanding that several Hyundais have been recalled due to excessive oil consumption issues. The contact has stated that during one incident, the vehicle lost power going up an incline. The oil levels were checked and were normal. A tow truck mechanic was able to get the vehicle started back up so that the contact could drive it home. The contact took the vehicle to a mechanic and was told the catalytic converter was bad. Unfortunately, the part is on back order and the vehicle is unable to be repaired. Aside from the catalytic converter, the vehicle has an oil consumption issue.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
While driving the vehicle on the interstate, crossing the expansion joint on an overpass, the check engine light illuminated. Immediately following, smoke began coming from under the hood. Pulled off the side of the road to check, and flames were coming out of the car. Quickly removed what personal items that were possible while the car started becoming engulfed in flames. The car burned until the fire department arrived and put the vehicle out. While we cannot be certain, it is believed that the high voltage wiring chafed and arced leading to the fire. If it wouldn't have been possible to immediately pull to the shoulder, the car would have been engulfed while rolling and could have lead to death. The car is a total loss.
