This is the 2nd time the 'check bsd system' alarmed. First time was almost a year ago, and the dealer change some sensors (charge me for it). Now on 02/06/2021 when I started my car in the morning and the message error appears again. Still waiting for the dealer to grant me an appointment.

I got the oil changed on my 2016 Sonata. The mechanic that changed my oil told me the engine was low on oil when he changed the oil. A week later I checked the oil to make sure the oil level was good still. I had to add three quarts of oil to the vehicle. The next week my wife complained about a weird smell coming from the car. I checked the oil again and the engine oil was low again. I added three quarts of oil once again. The Sonata is driven in the city with alot of stop and go traffic. Not one time did the check engine light come on to warn us of low oil. Additionally, we never observed any oil spots in the driveway from leaking oil. Now we continue to smell the weird odor and I have to add oil to the car every week. No visual oil leak is seen and the driveway does not show signs of a leak.

While driving, the check hybrid system warning light came on. This began in September 2020. I would pull over and turn the ignition off then restart the vehicle and it would be fine and light would be off. This happened a few times and then on a long distance trip I shift it off and it took about15-20 minutes to restart. The dealership said it was the relay assembly and that it was a recall. It had completely melted the casing around my battery. They replaced it for free in October. Now in January it has started the same thing. I will never get another Hyundai. This car has had more problems than my 2000 Honda Accord that has 300,000 miles on it. And my Hyundai only has 84,000.

During long distance driving once the vehicle is stopped for gas the hev warning light comes on. The car will not re-start for 15 -30 minutes. Once restarted the check engine light comes on. This has happend 3 times. The first two the thought was a long distance drive in the heat of summer. This last time it was fall/winter so the hypothsis of summer heat was thrown out the window. The most recent time the gas mileage went down drastically and the voltage for the electric system was acting erratically. The check engine light was on for 2 days but the car was only driven to the dealer. The dealer quickly found the problem and repaired under warranty "open recall". the car has not been driven any long distances since. The diagnosis was "main relay/power relay/cable (20-01-003H) caused by T4M. Power relay module melted at relay" installed 37583-A8000-qqh: Relay-high voltage main, 37514-G0000-qqh: Relay assy-power, replaced power relay assy module per campaign "warranty" hope this information helps others....hope this is truly the fix as it is an "open recall" that should be a recall". glad this did not cause a fire.

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.

While the vehicle is moving the check hybrid system warning light beeps and comes on. The message request to turn engine off. The gas engine sometimes will cut the power to the vehicle causing the vehicle to loss power on the road.

Numerous posts and this has occurred to me numerous times within the past 2 months. After driving vehicle on the freeway, and getting off to get gas or stop to get groceries or anything, when the vehicle is turned off, check hybrid system light comes on and vehicle is disabled. Will not start or attempt to start for at least 20 minutes. When vehicle starts back up the check engine light comes on and stays on until the vehicle is turned off again then the cel goes away. Sounds like numerous people are having this issue, I however have been lucky that it hasn't shut off while driving on the freeway, sounds like many other people it has. There needs to be a recall or the car be labeled as lemon or something.

At about 58K miles I started to notice when I turned the turn signal to indicate a left turn the right blinker would come on and then after a moment switch to the left or not switch at all. This was totally random. I tried to capture it on camera to show my local dealer before the 60K warranty ran out but I could never capture it because it was so random and they could not replicate it. Over the last year the issue has gotten worse where nearly every time I use the left turn signal the right signal will turn on instead. The last time my car was in for service I mentioned it again and told them I think they can replicate the issue because it happens nearly every time now. When I indicate a left signal and the right signal comes on other cars think I am merging into them while my signal is stuck. The signal stock seems to have an electrical issue sending the correct signal to the lights. This is a clear safety issue and I hope it does not cause accidents as the signals become stuck. This occurs regardless of vehicle speed.

When driving sometimes the bsd system turn off without any advance warning, this could cause accidents, the blind spot collision warning Hyundai need to be reviewed well and address the issue. Many people complain about this.

After filling tank for long road trips the car does not start and the check hev hybrid system light comes on.

- Cary, NC, USA

I stopped for gas and when I attempted to start car an alert came across my screen saying car has a hev issue and check engine light. I would have to wait for 15 to 20 minutes for my car to start again. I was assuming it was bad gas but mechanic confirmed that it wasn't a bad gas issue. I went to the dealership and they said it's a potential electric issue that my warranty does not cover. I had yet even exceed mileage above 70000 miles. I believe this is an issue that is an inconvenience to me and other drivers because it is starting to happen more frequently. This could be a father for anyone in a urgent situation and need to be able to activate the car to leave immediately. Thank you for your consideration.

The car when driven highway miles will not crank when you stop the engine. The check hybrid system light message comes up. The car will not start for 15 to 45 minutes. The engine light is on once the car starts but the next day there are no lights or diagnostic codes. Stopped in a drive way and had to push it. This is not the first time. Happened 3 other times.

The contact owns a 2016 Hyundai Sonata. While driving approximately 40 mph, the contact heard a ticking noise coming from under the hood of the vehicle. Also, the oil light and check engine warning indicators illuminated. When attempting to drive the following day, the vehicle would not go past first or second gear. The vehicle was taken to an independent mechanic who then referred the contact to the dealer. The contact had the vehicle towed to route 46 Hyundai (located at 28 route 46, hackers, NJ 07800, 908-850-0050) where it was diagnosed that the engine failed due to fractures with several engine pistons. The vehicle was not repaired. The manufacturer was contacted and opened case number: 16076286. The approximate failure mileage was 104,000.

On September 1,2019 my car wouldnt start. I purchased a battery and a it turned over. On September 8th I drove to get a oil change and tune up which seemed abnormal when I got home. There was a ticking noise. I wasnt sure what was causing the ticking noise so I didnt drive the car. On September 9th I got into car and started it when I noticed a knocking noise, the noise accelerated once I pressed on gas pedal so I didnt want to drive it. My check engine light is rapidly blinking.
