While driving my vehicle when I go to accelerate there is a clicking or ticking noise and the car acts as if it doesn't want to accelerate. I've tried getting a mechanic to look at the vehicle and have even replaced parts but the problem continues. I tried looking online and I find a lot of people having the same issue.

I got my car in 2017 and it's 2016 Hyundai Sonata. The month of August 2019 after an oil change my car begin leaking oil as well as shooting out oil from the oil reservoir. Took it to pride Hyundai in batesville ms, they said they couldn't find any oil shooting out from the oil reservoir when I know it was. All they did was diagnose for free of charge, and tell me I needed a oil change did by them. I took it for the recall that was on it ECM and they did, but they said it wasn't another recall on it and it is still leaking oil and shooting it out from the reservoir under the hood. Some need to be did about this cause it can cause the engine to fail and I'm still paying on this car and only had it going on two years next month.

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.

I went into the dealer to get an oil change on 3/14/2019. The dealer chose to do a factory recall 50hyz. Soon as I left the dealer my car started stalling on 495 North towards tyson corner in Virginia, jerking and lost drivetrain power. I could get to 60mph and the car wouldn't respond after that. I took the car back to the dealer. I was told the software updated bricked my Sonata. The dealer told me they will order the part and will come in 3/21/2019 which is today. Only to get a call saying the part is on back order into May. My question is why isn't holding Hyundai accountable for this" my car isn't the first one to get this software update so if Hyundai knows this software is going to brink peoples car how in the hell are they allowed to keep doing this recall when they have no clue when the part will be available"

Vehicle fails to accelerate or acts as if it is going to shut off and just recently I got in vehicle started it and the check engine light came on. Vehicle shut off while starting it finally it started up I took it to auto zone to read the code. They advised me the code P200A is very common among Hyundai and it most like is the vcma that needs replacement. After doing further research there are many complaints about the vcma failing and having to be replaced. My warranty is up on my vehicle and I feel this is something that Hyundai needs to address as soon as possible given this is a common issue and could cause harm to driver or others while driving that vehicle. Also when attempting to accelerate and the vehicle fails to do so there is a rattling noise when pressing the gas petal.
