2017 Hyundai Tucson: engine overheating

Filed May 4, 2026 · Acceleration, Engine · GA

My 2017 Hyundai Tucson is experiencing dangerous, sudden engine stalling, which are symptoms directly matching Service Campaign T1B. These critical safety issues surfaced following a total engine replacement in June 2025. Despite the vehicle being within the 12-month/12,000 mile workmanship warranty, the dealership is refusing to honor this coverage or offer goodwill assistance. My claim is based on a documented pattern of physical and technical negligence: - Failure to Update Software: The dealership failed to perform the mandatory ECM/TCM software integration (Campaign T1B) during engine swap, which is required to prevent the exact stalling I am now experiencing. - Dismissal of Warning Lights (Code P0456): One day after the engine replacement was “completed,” I returned to the dealership because the Check Engine Light illuminated with Code P0456. This was dismissed by the service provider without a proper diagnostic resolution, despite being a direct indicator of improper vacuum line reconnection during the engine installation. - Mechanical Negligence (Coolant Leak): Post-engine swap, the vehicle developed a coolant leak, which was a direct result of improper reassembly. Additional proof of the lack of due diligence during the repair. The lack of follow-through, combined with the dismissal of a life-safety defect and poor physical workmanship, suggests a total failure in the case management process. I am urgently requesting assistance to resolve this hazardous situation.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at various speeds, the vehicle made an abnormal clacking sound. The vehicle was taken to an independent certified mechanic, where it was diagnosed that the catalytic converter had failed and needed to be replaced. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the mechanic, where the catalytic converter repair was performed. The contact stated that after the repair, the contact noticed that the instrument panel would turn black and the infotainment system would become inoperable intermittently; however, both systems would reboot independently. Additionally, the vehicle was taken to an unknown dealer, where the air compressor was replaced due to heating system failure. The contact stated that the instrument panel failure recurred intermittently. Additionally, the contact stated that the vehicle was overheating. The check engine warning light was illuminated and the message "Engine Overheating" was displayed. The vehicle was taken back to the independent mechanic, where it was diagnosed with engine misfire. The mechanic determined that the head gasket failure had caused oil to contaminate the coolant reservoir. The vehicle was not repaired. The dealer was contacted and confirmed that the VIN was not included in a recall. The manufacturer was not notified of the failure. The failure mileage was unknown.

On March 9, 2024, I was driving when suddenly a warning light sounded from the dashboard that the engine "overheated" and there's a loss of power. I was very scared driving for the first time in my life. Before I pulled over to a safe place, a driver nearest to my car pulled his window down and shouted that my car was smoking. I was terrified. This incident triggered my husband's mental health conditions. I called my niece who is a registered nurse to help us. I called my car insurance for towing to the next dealership that I called about what happened. After I rented a car, I went to the dealership. However, the Service Department was closed after 4:00 pm. The next day (Monday), I received text messages that they're working on my car and the only communication was "text messages." I was stunned! The next message was transmission problem, the cost of repairing it, and authorization to fix at $1,581.40. Because my rental car was not cheap and needed a car to doctors and other appointments made on that week, I agreed to proceed. After I signed the authorization from text messages, I got a call from a service advisor to acknowledge the cost of the repair. I asked about the engine and he said it's okay. By Wednesday afternoon, I received a call that my car was done. Before this incident (2 weeks?), I called the same dealership when it's time for an oil change, but was told at 72,000 miles. Then I received a call that my car needs a transmission check up for $1,200 or more, but I told him I'll wait for the next oil change. Last year, I reported to other dealership that my engine light was on, but was told to go to Autozone. I didn't do it because the light didn't appear again. My car has been maintained by local dealership since I bought it in 2016. One dealership would not pick up my calls after fixing the side door locked from inside/outside. As this is not a traffic related incident, my car insurance doesn't want to be involved.

I have had engine problems with this car since I purchased in 2017. These issues range from transmission overheating, water pump replacement, and most recently, the car's engine failed while driving. The vehicle is now with the Hyundai dealer, who confirmed that a new engine replacement is required. My wife, toddler and 6-year old son where in the car when it failed while stopped in traffic. The car has excessive oil burn; therefore, I would purchase and add oil every 2-3 months to ensure oil levels do not reach an unsafe level, on top of regular oil changes. The oil light has never turned on despite these issues. The engine light came on only once after managing to restart the car and struggling to get the car to the Hyundai dealership after numerous start and stops on the way. For a car with less than 100k miles (6 years old), the car is the highest maintenance and poorest quality car I have ever owned. The car is unsafe and I have genuine concerns about other peoples' safety as it relates to the engine in this Hyundai Tucson. Additionally, my wife and I are not aggressive drivers and both have excellent driving records. We always take good care of our vehicles. This car was simply built poorly, as confirmed by the Hyundai dealership after stating that I need engine. I will contact again if Hyundai does not honor the warranty for this vehicle (10 year, 100k mile, original owner).

My Hyundai Tucson beginning at 65,000 miles Began consuming more oil than normal. There was a transfer of title through a family member with the vehicle and was not aware that in that case the cars 100,000 mile warranty is no longer valid. It is then reduced to half that or 60,000, one of the 2. I brought the fact up to the service rep at Hyundai that it was going through a lot of oil and they stated that it was normal with multiple cars that Hyundai produced. The oil was burning off and no detection of leak and no check engine light has ever came on. It never over heated. I then brought this up to Hyundai at about 92,000 miles and thats when I learned about the warranty being voided because of the transfer. The car at the time is running just fine but still burning oil and still nothing from the dealership about any issues because the check engine light never came on. Until I was going home one day and the car began to stutter and losing power . It was struggling to produce power and I finally pulled over to a safe spot. It did not wanna start after that. I had it towed to Hyundai service center and they later told me that my engine needed a fuel system flush. They did that and I drove it just fine for about a month. Then it did the same thing only this time the check engine light finally came on. The code was giving them a misfire of 2 cylinders and was not holding enough pressure. They then said my motor was gonna need to be replaced and that threw me off. I feel like that should have been detected much earlier but without any sign of overheating or engine alarms it just kept running up until that point of the motor no longer running. I feel that if I were to get some kind of check engine light earlier in then it is possibly that this could have been avoided. I feel like this issue remains and is well overlooked to many of their vehicles. I just need a new engine not looking for money or anything else, just a car that is reliable and safe.

When driving in stop and go traffic, specifically on an incline, the transmission overheats and a burning/melting rubber smell is emitted from the engine. When climbing a long hill in slow moving traffic, the car displays a warning message saying that one should step on the break while on the steep incline. So instead of moving up the hill at a low steady speed using the accelerator, I must apply the break and stop the car on the hill, wait for a gap, accelerate to the car in front of me, and then stop again. When attempting to accelerate from a stop, the car lurches and shakes while making loud clanking sounds (similar to the sound you might hear before your car stalls out if you're not very good at driving a stick shift). After about 20-30 mins in traffic on the incline, one can smell an the burning odor and two out of three times another warning message came on the display that the transmission is overheating and that I should pull over immediately. It is extremely dangerous to park on the side of the highway and I have had to do three times in the last four weeks. Besides the transmission overheating and lurching on inclines, the vehicle also has acceleration issues on flat ground. For example, after being stopped at a traffic light I apply pressure to the gas but the car barely moves, the rpms begin to increase as I apply more pressure to get it moving, and then all of a sudden in clicks and jerks in to gear speeding away. This problem has left me in the middle of an intersecting with oncoming traffic, luckily no one has been injured yet. The delayed acceleration also occurs as I drive up my parking garage, as the car slowly moves along the accelerator has no affect until suddenly the car quickly accelerates to an unsafe speed in the tight parking structure, again luckily no pedestrians have been injured yet due to the malfunctioning vehicle.

Six month old car....car hesitates when you press on the gas petal from a stop. Must give yourself a more than normal amount of room to pull out into traffic just in case the car hesitates as to not get into an accident. Also while driving thru a christmas display (very slow moving, stop and go traffic) with my family including a five year old child the transmission high temp alarm came up on the car and we could smell how hot it was getting. Had to pull over to the side of the road and shut the car off for a while in very cold temperatures at night with our young daughter. Waited a while started the car up and then it wouldn't shift right. Made an appointment with the dealer (hazleton pa auto mall) I purchased the car from to have it look at. At the appointment I was told by a man and women at the service desk that the overheating is a normal reaction to stop and go traffic. Never had a brand new car with 7000 miles on it overheat and leave me sitting on the side of the road. Tuscan's with the dual clutch transmission are a danger to the owners, their families and the public in general.
