2017 Hyundai Tucson: multiple warning lights

Filed Apr 22, 2026 · Electrical, Engine · GA

The vehicle has a difficult time turning over when cranking, the RPMs are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [XXX] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai Recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai Recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle.

On [XXX] my daughter was driving in Meridian Ms and when she was at a red light the 2017 Hyundai Tuscon that she was driving started shaking and all the lights on the dashboard came on and she couldn't drive because it wouldn't move. She called a tow truck to have it taken to Firestone. When they looked at it, they said the reading was spark plugs and fuel injectors that needed to be replaced. After they did that, the car still would not work. We paid 1300.00 dollars for them to do this. We then had it towed to Hyundai in Flowood Ms. We learned that the whole engine needs to be replaced. We Take very good care of our cars and this shouldnt be happening. I see that there is an extended warranty for 2017 tucsons with engine failures, but our particular engine is not included in this. We have a turbo 1.6. I asked Hyundai why these particular motors are not included and they didnt know. I found alot of people are having the same engine issues as I am and i think Hyundai needs to help me out. The replacement cost of this is going to be about $10000.00 dollars. My car only has 84000.00 miles on it. Hyundai knows that there are problems with these vehicles but refuse to be any help what so ever. I just dont understand why my engine isn't included in their 150000.00 mile warranty. I dont know where else to turn for help. Thank you.

THE CAR STARTED TO HAVE PROBLEMS WITH ACCELERATION DO NOT ACCELERATE MORE THAN 60 miles per hour and turned on the signal the engine and to get to 60 mph it goes slow little by little without strength since it only reaches 2000 rpm it does not go higher than there. In addition, all the lights on the blackboard came on, which means that I can't tell if there is something wrong with the car or not because everything is on. The proximity sensors don't work, and I get the code for engine is P1326 and the anti-Lock Brake System the computer show the code C1211-02, C1207-02, C1210-02, C1208-02 Y C1209-01.I took it to the Hyundai agency in Miami Lake where I bought it and where they told me that the car had 10 years or 100,000 miles of warranty and when I arrived the person who received me without passing the car to diagnosis or anything told me that repair costs you $700,00 and tells me that to my warranty covers the engine, the engine has to be completely damaged; I explained to her the engine was in bad shape that it was better to do the repair than to change an entire engine if it was still being used, but she was still in the same negative until she left. I need to make this report because I didn't have any help from the Hyundai that sold me the car and which is still under a factory warranty. I consider this a violation and abuse of consumer rights by deceiving the American people with a guarantee that they then do not want to fulfill

I have had an ongoing issue with my 2017 Hyundai Tucson since May 17, 2021. Like many other owners, I have recently learned about the recall on engines for the 2017 Hyundai Tucson. In the information with the announcement of the recall, the article stated, “The issue has caused at least 18 fires, but no injuries, according to documents from the U.S. the federal safety agency”. I wanted to know if my vehicle was one of these 18 fires? If it was, I would like to know that I will be covered under this recall, and the engine in my vehicle will be replaced. I can begin to be reimbursed for the $1,000s of car rentals that I was told would be reimbursed before my warranty claim was denied. If it is not one of those 18 cars? Why not? I will give more information below on what happened to me and my car. Through further research, Attachment A on the federal safety agency website states that “As of the date of this filing, Hyundai is aware of 45 fires related to the recall condition”. Once again, I ask if my vehicle is on this list? If not- why was it not after the engine fire and the below happenings occurred to me in May 2021. Happenings On May 17, 2021, I was driving home from work on Interstate 195 in New Jersey. My check engine light came on the previous week, and I immediately brought my car into an auto body to receive an oil change and a 25 point maintenance inspection. But, unfortunately, the check engine light went off. While traveling on the freeway at approximately 65 - 70 miles per hour, I could feel my acceleration beginning to get slower and slower and harder to use. I was pressing entirely on the accelerator, and the car continued to go slower Suddenly, the acceleration stopped completely, and all the lights on the dashboard went on. I noticed smoke started to appear from under the hood and from the tail of the vehicle. After nearly being hit by another car, I was barely able to get into the shoulder. I just so happened to break down on the part of

I bought this car as a certified pre-owned vehicle 5 weeks before this incident occured... While driving on a highway with a full load in the trunk, several warning lights progressively came on: traction control, downhill assist, oil and emergency brake. I continued to my destination (airport parking garage) as there was nowhere safe to pull off. As I approached the airport, an additional large red triangle illuminated in the center of the dashboard saying "check ----" (4 letters, I don't remember what they were). I stopped to get my parking ticket, and the car rolled backward as I tried to begin moving. I gunned the engine, and was able to get to a parking spot, but felt the car had very little power. On my return approximately 36 hours later the oil light was still on; so it was towed to the nearest Hyundai dealer. The tow truck driver commented on it having low power as he tried to drive it onto the tow truck ramp. This Hyundai dealer was unable to find anything wrong. I drove it to the dealer from whom I had bought the car; they tried to recreate the situation where this occurred, and said they were unable to do so. I am concerned as this problem has not been diagnosed or repaired, and did cause a partial loss of power, which could have caused an accident. My dealer has traded me out of this vehicle into another car, as I no longer felt safe in this one.

Engine failure at 121k miles. I drive long distances for work so the miles are super easy not stop and go. I noticed a knocking noise at certain throttle pedal positions, I pulled into a gas station and checked the oil and it was barely touching the dip stick so I bought a quart of oil and this put the level in the middle of the acceptable range on the dip stick. I proceeded to get somewhere closer to my home. As I was driving on the interstate the check engine light came on and started blinking so I got off onto the exit and at the top the motor made a hard noise and stopped and all the lights came on the dash and smoke came from under the car. There was oil on the ground so I assume the oil pan had a hole from a rod failure. I change my own oil every 7500n miles when the factory setting tells me it's time. I use mobil 1 synthetic oil and a good filter every time. I had the oil changed the first time at hyundai of ontario, calif and the second time at jiffy lube in redlands, ca. The price for synthetic oil change was ridiculous when I can do it for half minimum. Hyundai has said since I have no invoices for oil changes they will not cover motor fully? I know the computer can be accessed to see the dates when I reset the meter miles. I know since doing my research hyundai has had the very same problems with prior year cars. I believe they should pay for this problem a car like this should last well into 200 to 300k miles when taken care of properly. I have had a honda and toyota that did high mileage with no problems. Hyundai still has a problem with the 2.0 liter motors. The warranty needs to be made longer to 200k miles if they have really fixed the problem with this motor. I will never buy or recommend a hyundai vehicle to anyone!
