I keep having the same issue with this vehicle's fuel/propulsion system, power train, engine, cruise control. This vehicle is need it's fuel system cleaned now for a 3rd time in less then 2 years. I have done the high mileage maintenance on it as well. I drive the vehicle less than 5,000 miles a year. When I am driving the vehicle, it struggles to speed up, making me press on the gas repeatedly to get to the indicated speed limit. The vehicle does not slow down as it should when pressing on the brakes. I have to press repeatedly over and over and harder on the brakes in order for it to slow down. The vehicle jerks, speeds up without me pressing on the gas and sometimes it will not stop when prompted. I cannot put this vehicle on cruise control, because it speeds up and out of no where, it accelerates causing me to almost collide with another vehicle or object. Even when the vehicle is not in cruise control, the sudden jerks and acceleration puts me, my children and others in harm when it suddenly speeds up, jerks or will not stop in time. It makes a loud noise and jerks even when the car is in a resting position. It loses power, it speeds up when i need it to stay the same speed or slow down. I fear this vehicle is unsafe. I have reported these issues and a few more to the dealership who never responded, so I had to go over their heads, then finally I got a response from their Consumer Affairs' Department, as well as the BBB and they state because of the vehicle's age and/or mileage there is nothing they can do about it. Please help me. This is the only vehicle I have, and I am a single parent who cannot afford another vehicle. What is going on with this car? Why do I have to keep struggling to pay for something to get fixed and it is still not solved. Below, it ask for a date, but it is multiple dates, not just one. I have listed the first time it occurred. Thank you.

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won-??t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.

Engine is constantly burning through oil. I would get my oil checked 4 times more just to make sure I had oil and even then it would burn empty. I did not have a leak. This cause my engine to blow. This was unsafe as I could have been driving when this occurred. This is being confirmed by a certified Hyundai mechanic. No warning. Other Hyundai cars have a recall for this SAME engine issue but not my model and make

Hello, I am writing in reference to my 2016 Hyundai Sonata that was taken to McDonough, Ga Hyundai on March 29-31st for recalls. We purchased the used vehicle in November 2022 with a 3 month warranty. We took the perfectly running car to the dealership to get 2 recalls done and was expecting to receive our car back in the condition that was given to them with the upgrades the following day. However, the next morning we received a call stating that when they took the car out to test it out knocking sounds were heard. The service man stated that the noise was probably the engine getting ready to blow. This was a completely surprise because first, when we took the car in there was no evidence of a blown engine. Next, what do you mean about to blow? These were the direct questions I asked. He informed us that there was a class action suit in reference to these engines and ours would fall into that. He stated to leave our car there because it happened there. We later received a call stating that they needed to file a claim with the Main office and get back with us. We were were provided 2 loaners after 3 weeks of waiting. However, we get a call today stating our car is ready for pick up. Once we get there we were informed that they have been waiting to hear back something and no response from cooperate. We were told the car is drivable and the knocking sound is faint. We were also advised to drive it and let the engine blow and then bring it back. Within 30 minutes the car shuts down without warning and we were stuck on the side if the street. There is several problems with this! One being our safety and safety of others. The next being the dealership knew something was wrong and told us to just leave. Lastly, whatever happened, happened on their watch because they called and told us. Now they are saying the claim was denied because the recall wasn-??t done prior. They also put in the system that the recall was done June 30, not March

1. The component or system that failed or malfunctioned is suspected to be related to oil consumption or engine failure, as indicated by the burning of 1 quarts of oil within 400 miles driven, premature burning of spark plugs (The spark plugs, which were replaced prematurely, can be made available for inspection upon request), stalling of car, not accelerating, and failing twice within a months' time. 2. The safety of both myself, my family and others were compromised due to the potential engine failure caused by the oil consumption issue. Engine failure poses a significant risk of sudden loss of power while driving, potentially leading to accidents or hazardous situations. 3. The problem was speculated by an independent service center. The dealership has been unresponsive and failed to address the issue adequately. 4. The vehicle was taken to the dealership on Tuesday, 6/27/2023, following its tow to an independent service center on Monday, 6/26/23. During the diagnostic, an engine issue was identified through the appearance of a specific code. The dealership submitted a report to request approval for an oil consumption test, but it was denied due to the vehicle being over the 5-year/60,000-mile warranty, which I was previously unaware of. 5.Prior to the failure, there were warning lamps, messages, and other symptoms of the problem. In July 2022, the vehicle started to stall and the check engine light came on. A diagnostic test at Autozone indicated a possible VVT solenoid issue. The car was taken to the dealership on 8/8/2022, where they claimed the car was operating fine. On 5/6/2023, during an oil change, an independent service center checked the stalling issue due to the intermittent check engine light. They mentioned oil consumption but advised me to monitor the situation. However, on 5/22/2023, the car stalled and died in a parking garage, resulting in a delay of 5 hours before I was able to drive it home. Subsequently, on 5/23/2023, I took the car to the

My car is under an oil consumption recall that will replace the engine if anything happens. My car continues to use oil and the dealer claims it has nothing to do with the oil consumption. They want to charge me over $1400 to keep replacing different parts of the engine. What can I do? The dealer is Taylor Hyundai on Washington Road in Augusta, GA.

- Evans, GA, USA

The engine has a oil consumption issue. Our vehicle has had oil consumption issue since 55000 miles when the vehicle was still under warranty, the dealer sold me a oil pressure sensor and the vehicle had no oil in it. Which I found out about later. The vehicle is a hazard due to fact that with the oil consumption the engine could lock up while driving and become a hazard in the roadway. After burning over a quart of oil every 1000 miles the dealer explained it is normal consumption per Hyundai guidelines. That is a complete oil change in-between oil changes. After bringing this up to the dealer. they performed a oil consumption test and the vehicle failed. Dealer wanted to charge me $1100 dollars to perform an engine flush and warranty only pays 2 hours for this procedure. They performed the procedure at their cost. Another oil consumption test is performed and it failed as well. The dealer put in for an engine replacement and want me to pay $4000 of the bill for the new engine. Which only has a 12 month or 12000 mile warranty on a new engine. I have done all of the services required for this vehicle the Hyundai has dragged their feet for over a year. I do not feel I should have to pay anything for a known issue with Hyundai. The dealer don't get paid that much for warranty and I feel they are trying to pass the cost onto the customer. When the warning lamp illuminates there is on 2 quarts left in the engine and this engine take 5 quarts to operate.
