2017 Hyundai Tucson electrical problems

ELECTRICAL SYSTEM

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.

Following the knock sensor detection system update, this car has a P1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e.g. getting on a highway. The car is limited to ≤2000 RPM and ≤ 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.

I am writing regarding a serious incident involving negligent automotive service performed by Jiffy Lube Store #687. On October 24, 2025, I took my 2017 Hyundai Tucson to this location for a standard oil change. I trusted that the service would be completed properly and safely. However, on November 21, my vehicle’s oil lamp unexpectedly illuminated. Concerned, I returned to Jiffy Lube on November 22, where employees informed me that they had “sealed the small leak and topped [my] oil,” adding that I was entitled to two top-offs between oil changes and “should be good for two weeks.” Tragically, the very next day, November 23, the oil lamp flashed again. My vehicle then shut off while I was driving, with my children in the back seat. This was a frightening and dangerous situation for all of us. I am now left confused, stressed, and unsure of the full extent of the damage.

My 2017 Hyundai Tucson has completely broken down will not go into reverse had a diagnostics at Hyundai. I thought it was going to be covered because of the class action suit. My car apparently was not in the recall or the suit. I don’t understand I have the identical problem of the dual clutch transmission issue. I’ve tried to get Hyundai to do good-faith repair they refused. I’ve contacted Carmax where I purchased the vehicle. They had the car when the lawsuit was finalized I didn’t know anything about the lawsuit or the problem with the vehicle. I’ve had the car for five years it’s at 85,000 miles. I don’t know what to do.

The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.

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.

Rear driver side door suddenly will not open from outside or inside. A rear passenger would be essentially trapped in the car should an incident/accident happen. I googled and it seems this is a well known issue affecting several model years of Hyundai, including my 2017 model. I do not see a recall for this extremely dangerous issue.

I am writing to report a serious issue with our 2017 Hyundai Tucson. As the first and only owners of this vehicle, we have diligently maintained it through authorized dealerships. However, in May 2023, while driving on the highway, the car suddenly lost power and would not accelerate beyond 30 mph. There were no warning lights or indications prior to this incident. My wife managed to pull the car to the side of the road and slowly drove it to the dealership. Despite having only 30,000 miles on the odometer from personal use, we were shocked to learn that the engine had suffered significant damage due to low engine oil. Notably, we had recently serviced the vehicle at the same dealership just a few months earlier. The dealership informed us that the engine needed replacement, but the process took nearly a year. During this time, we were left without our vehicle, causing considerable inconvenience and financial hardship due to renting replacement vechile . We find it concerning that an engine failure occurred despite our regular maintenance and adherence to authorized service centers. We kindly request an investigation into this matter and hope that steps can be taken to prevent similar incidents for other Hyundai Tucson owners. Additionally, we urge Hyundai to address this issue promptly and transparently.

The vacuum pump on my 2017 hyundai has a faulty cap resulting in an electrical error to the CAN system. This causes dash lights abs 4wd parking break stability control tpms sensor check engine light to eliminate and the speedometer to not work. All of the systems are not opperating due to the system not being able to communicate. It is illegal and a safety issue to not be able to use the speedometer.

On July 22nd, the duel clutch malfunctioned & caused the vehicle gear shift to no longer engage. The car does not move in Drive or Reverse. It can only be pushed in Neutral or towed. This occurred while I was driving home on the highway with no warning lights or prior symptoms indicating a potential issue. The vehicle has not yet been seen by Hyundai but they did say that since my VIN was not registered to the existing recall, there is not much they can do & any repairs would be out of pocket. It has been seen by our family mechanic, PepBoys & has currently been sitting at AAMCO with no solution as of today since August 2nd. Geico said since this is a mechanical issue & not an accident, they cannot assist. Carmax Customer Relations (where I purchased the Vehicle on March 12th, 2023) has been informed but so far offered no solutions. I am told they cannot offer much assistance due to the 90-day warranty being surpassed, extended warranty not being purchased & the current milage on the car. A case with Hyundai Customer Relations has also been opened as of today, August 15th & they are escalating the issue to their legal department as we are considering taking legal action at this point.

The 2017 hyundai tucson will trap you inside the car. The doors will work intermittently and other times they simply will not open. Even when the car is unlocked. This was recalled on certain models and years but not this one. Huge safety concern being trapped inside the car or stuck outside car.

Car has been hesitating to start this last week, Friday 6/2/23 warning lights came on & air conditioning stopped working. My local Hyundai shop is booked 2 weeks out so I already have an appt for 6/13/23. But on 6/2 I barely made it to a shop close to my home for a diagnostic check. Code P1111 was stored, cleared & retested. It's for fuel pump, circuit was tested & no faults were found & test driven with no return of code. Picked up car on Monday 6/5 with no issues. Tuesday car hesitated to start, 3rd time it started with no issue & no warning light/s. Today 6/7 around noon while I was making a turn the car completely shut off without warning. I've also noted that the oil level is always low, I have to check & put in oil at least every 2 weeks but there doesn't seem to be an oil leak. Also from stop to go at a light for example the car hesitates and then jerks forward. In the past I was told at a Hyundai facility that this is normal because of the dual clutch or something to that fact. The incident today was scary as there were a lot of cars behind me and cars coming towards me. The attached pic of warning lights was from Friday, 6/2/23.

Powertrain: Vehicle losses power especially going up inclines or hills. This happened before and I spent over 4500 dollars on repair of a catalytic convertor that failed. This was Late may of 2022. Now the car is back at a Hyundai dealership because the Catalytic Convertor has failed again it is Feb 2023. The car has extreme oil consumption which is one of the causes of catalytic convertor failures. The car in November of 2022 had a loss of power again but this time coils failed. Had all three coils and spark plugs replaced. The certified mechanic shop gave me the spark plugs and it was if they had a black felt on the tip of them. The mechanic said this was a sign of high oil consumption. High oil consumption is also a cause of coils and spark plugs failing prematurely. I have records to show how much oil I have bought and it is about 3 quarts every 1-2 months depending on how much I drive. This is extremely high and a sign of a faulty engine. It puts me in danger of being rear ended in traffic or on an open highway because it losses power. I use my car for work and sometimes that work takes me to small country towns. My work sometimes mean I get back when it is dark or get up when to get to work when it is dark. A car failure on a dark country road is unsafe. Yes a Hyundai dealearship in Decatur and Lubbock TX as well as a certified mechanic in Keller Texas can attest to no warning lights or codes and the car has high oil consumption. Inspected by two different hyundai dealarship service repair locations NO warning lights, no check engine lights, nothing to give notice of a problem about to occur. I have tried to deal with Hyundai but they refuse to accept that the issues are due to a bad manufactured engine. However all the signs point to that is the problem. Lastly the check brake light comes on but mechanics can never find a problem. So they replace the bulb but it just keeps happening. It will come on , stay on for a day , then go off. Just periodic
