2017 Hyundai Tucson Speed Control & Cruise Problems

The contact owns a 2017 Hyundai Tucson. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond while stopped at a red light. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 95,000.

Sole owner of 2017 Hyundai Tucson with approx 55,700k miles. Check engine light on and car not accelerating properly. Had same acceleration problem a year ago without engine light, Hyundai dealership stated I needed software update on anti judder gds, update was completed by Hyundai and the issue has reoccurred.

My car has been burning oil for over a year. there is no leak. I have been putting three quarts in every 4 to 6 weeks. I have now replaced two coil packs and the spark plugs. my engine light is on because it said 3 and 4 was misfiring so i recently replaced those coil packs and now it said spark plug and i replaced it again as well. so the engine light coming on and what it says the problem is is wrong. now when i push the gas it is knocking or missing. not sure how to describe it. no one has looked at it other than a friend that is a mechanic and he says its probably the engine because this kind of car has these problems.

My car has been having engine problems causing it to stall while driving. It won’t go past 20miles per hour even if I press on the gas FULLY. This has been happening on and off for a couple of months now. It also burns thru my oil change in less than a week. I took my Hyundai into the dealer multiple times because of the way it drove since 2019 and they always sent me away saying that it was normal. But this car has been a constant stress in my life. Driving it has felt dangerous. Something is definitely WRONG with it and I’m not sure why this recall on the engine now powering up hasn’t hit yet. Death trap of a car.

Engine check light came on on 1/4/24 took it to dealership they ran a quick check and they said it had multiple misfires. The car has a lot of carbon buildup and they recommend a 24 hour cleaning which will cost me over $700.00. The car stalls and starts shaking as I speed up. I don't feel that a care with less than 70,000 miles should have this problem. Mine also has now been using up the oil very quickly.

The car does not accelerate from a stopped position and when driving it does not shift or allow acceleration. This is especially an issue on hills or when trying to increase speed on the highway.

I am not a mechanic but when I drive my vehicle, I feel like it doesn't have enough amps to move it along like it's missing something. I have pressed on the accelerator and heard a "winding noise" like the little engine that could but wants to. This is a horrible car!!! I have only had this vehicle for a month and it's a nightmare to drive. It sometimes does not accelerate, and the take-off is unbearable gives me the impression I will be rear ended one day. It even jerks and sputters, even the "rpm" feature shows high acceleration at inopportune times. I had a diagnostic performed and was told the plugs and ignition coils needed to be changed so I did that to the tune of $400 for the parts, and now not even a week later I am being told I need to change them again. How can this situation be rectified? I don't have another $400 every month in addition to the payment and insurance to replace those things every month. I want to know if you all have a fix for this to prevent all this unnecessary money from being spent. I am aware that a tune up is necessary but every month. Please tell me how this can be fixed thank you.

Engine stalled in the middle of the highway. Could not get speed over 30mph to get out of the way of oncoming traffic even with the gas peddle pushed to the floor. Engine light flashing. Finally was able to get over to the side of the road with care bucking and jerking the whole way and stuttered to a stop.

The check engine light started flashing and the vehicle would not go over 25 miles per hour. Thankfully I was pulling into a parking lot when the reduction in speed occurred. If this had happened on the interstate (which I commute on regularly) it could have been extremely dangerous. Hyundai dealership never returned my calls about service, I had the vehicle towed to another service provider (Jensen Tire & Auto) who performed a diagnostic which showed codes P0300/0302/1326/0011. They also said the engine was 2 quarts low on oil and there was no sign of an oil leak. The vehicle mileage was at 74344. I had oil changed at 71579 miles with full synthetic, and at 66230 miles prior to that. There is no sign of oil leak where I park the car. I regularly change my oil and service my car according to the manufacturer recommendation (just not at the dealership). This problem is not on the recall list for this vehicle, yet there are several instances of this posted in online forums. (https://www.carproblemzoo.com/hyundai/tucson/engine-burning-oil-problems.php). This problem is not due to lack of proper care, but to a dangerous defect in the Tuscon 2017 engine that misuses oil and causes a sudden an unexpected decrease in acceleration.

I had recently just had gotten and oil change less than 2 months ago, I had to take my car back to the dealership because it was taking a while for the car to pick up speed. Once I took it into the dealership they told me my engine needs to be replaced. I know someone else that I know that has a hyundai as well and their engine completely gave out as well. What's going on with the engines. My car doesn't even have 100,000 miles on it yet, there's no way my engine should've gave out.

I took the vehicle in for a recall for unrelated issues to this problem at 90,000 miles (July 6 2022). The technician noted that the vehicle was leaking oil and it needed an oil pan reseal. I brought the vehicle back for this service on March 6 2023. Between the initial recall service and this service, I noticed that the vehicle was consuming a significant amount of oil, beyond regular consumption. On several occasions, after about 1000 miles after the oil was changed, I was adding 2-3 quarts of oil to the vehicle. Moreover, when the oil was changed, the technician who changed the oil, noted that the oil was very dirty despite only going 3000-4000 miles between oil changes. I mentioned this to the Lehigh Valley Hyundai Service Desk and that it was highly unlikely that an oil pan reseal would resolve this. They ordered an oil consumption test and instructed me to drive the vehicle for 1000 miles. I did this and brought the vehicle back in to Lehigh Valley Hyundai on April 1, 2023. They checked the oil, the technician ordered an oil combustion cleaning, and instructed me to drive the vehicle an additional 1000 miles before bringing it back in for the oil combustion test. During this period, I noticed that the vehicle lost a significant amount of power. During a drive back from Widener University, I barely had enough power to drive up hills on the Northeast Extension and almost got into two wrecks due to the lack of power. I took the vehicle back to Hyundai on April 8, 2023 and notified them of this issue. They checked the vehicle out and notified me that the catalytic converter was clogged and needed to be replaced. They gave me a quote of $4000 to complete this service. This service was extraordinarily high priced compared to other mechanic services which cost between $2000-2500. I checked with other services and they indicated that they did not have access to the part and only Hyundai had access to the catalytic converter.

It's like the transmission has hesitation before it decides to go. I step on the gas and it doesn't go right away, it takes a couple seconds and then the rpms go up really high. There has been no accident but this has happened many times.

Vehicle is showing transmission issues that match recall issued for same vehicle and model, problems accelerating and misfiring which appears to be dangerous too drive.

The contact owns a 2017 Hyundai Tucson. The contact stated that while reversing out of the driveway, the vehicle failed to accelerate despite depressing the accelerator pedal numerous times. The contact then firmly depressed the accelerator pedal, and the vehicle experienced an unintended acceleration at approximately 35 MPH. The vehicle drove into the neighbor's yard and crashed into the neighbor's house. No air bags were deployed. No injuries were sustained, and medical attention was not received. A police report was not filed. The contact was able to drive away from the scene. The insurance company had the vehicle towed to an independent mechanic for inspection. The manufacturer was not made aware of the failure. The failure mileage was approximately 24,000.

I was driving to work after dropping my son off and I took a right turn onto a street and my car slowed down and the check engine light came on, flashing. I continued to drive to work as I was one minute away and needed to get off the street asap. (where I turned had no room for pulling over). I parked my car. I had a prenatal appointment to go to, so I started my car. No check engine light when started until I got on the on ramp to the mass pike, my car went from 50 to 35 in a matter of minutes. I went into the breakdown lane until the next exit which was only a mile or so. I pulled into a gas station and called my husband to come get me as I still had an appointment to go to. After my appointment we retuned to my car and had it towed to the dealership as it is not safe to drive while pregnant. They told me it may be an engine issue and they will try to expedite my car. What annoys me is that this happened before and they claimed it was because I was over my oil change mileage and deemed it my fault and made me pay almost 300 for them to fix it. Yet I feel as if that just bought my engine time before it actually failed. This also happened with my 2015 Sonata Sport back in like 2018/2019 before someone rear ended me and totaled me. But what is my luck that this happens with 2 of my Hyundai. It is very frustrating.

The acceleration completely stopped, while driving in the third lane, northbound on the 15 freeway in the cajon pass. The dealership informed me the transmission is the cause. The car is still with the service department now. No warning lights. No check engine lights, nothing. The power in the car remained on the car acted as if it was in neutral.

the car was unresponsiveness when pushing the gas pedal, delay when accelerating, shaking, and the gears do not seem to change. this causes problems when trying to merge into traffic, make turns and anytime when acceleration is needed. We took it to the dealership said we needed a Dual Clutch kit however the vin does not have a recall therefore want to charge $2264.00. to fix the problem. it is obviously a manufacture defect. the car has not been inspected by the manufacturer, police, insurance representatives or others. There were not any warning lamps, messages or other symptoms of the problem prior to the failure. this problem has been going on for 6 months.

I HAVE FIXED EVERYTHING UNDER THE HOOD AND MY VEHICLE WILL NOT ACCELRATE OVER 60. IF ACCLERATE TO 61MPH IT WOULD DROP DOWN TO 40MPH
