2017 HYUNDAI TUCSON Electrical System Problems

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...

Sensors something to do with the motor and not sure where the other sensors is related to could be the motor as well. The safety was not good due to it shut off in the middle of traffic and making wraddling noise. I took the vehicle to the dealership where purchase from. They have done nothing besides fixed one thing that I know of supposed to been the surpension. But the other problems was not fixed No it has not been inspected by anyone The warning lamp come on and just blinking none stop

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 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...

Car cuts off when driving the speed drops down automatically stops the dash lights go out and can’t start it right away

1. After driving the car and turning it off, I get a loud bang coming from a gas tank. 2. Sometimes when making a hard right or left turn steering wheel vibrates, and the warning light for all wheel drive system comes on. When I turn the car off and restart it, it goes away. 3. After software installs due to recalls, when I accelerate my radio occasionally shuts off on its own, and then we’ll come back on on its own. 4. After turning the car off when I restart it occasionally the clock in calendar revert to 00:00 for the time and the date resets to 1/1/20.

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.

Unable to open passenger door on driver side. Unable to open from the outside or the inside.

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...

Unknown the car just start malfunctioning

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.

Vehicle caught fire damaging wiring harness. engine has hesitation, AC system was damaged by fire. recall shows electrical system/engine and brakes in recall. Hyandai refused to replace citing missed oil changes. oil was changed regularly but not always at the dealer. These particular problems are exactly what the recall was for, problem is design and manufacturing the oil change issue has no effect. I want these fixed as soon as soon as possible

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...

Faulty wiring on wiring from alternator led to electrical fire

My truck was stolen so most likely they messed up my ignition. Before this my lights keep going out every time I replace one a different one goes out. Wheel always going out of air and my truck always jerking when driving or breaking. I am a victim of the “Kia and Hyundai” boys in Baltimore city that’s going around stealing people cars.

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.

Problem with the engine

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.

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...

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 had my 2017 1.8L eco Hyundai Tucscon for 3 years now and recently it's been giving me signs of problems that are great concerns for safety, as well-known for this models; it only 62091 miles as of the day of this complaint. On Jan 15. 2023, I noticed that each time I start the car, it takes a little bit longer, then you hear a rattle sound and shaking of the engine block, then it start. Or the engine would suddenly slip, followed by a brief rattle sound while driving. I took it in for service to Manly Hyundai in Santa Rosa on Jan 27, 2023, but the mechanics there told me that they could not find where the problems are coming from, and that I would need to wait for an engine light to come on, as any diagnostic at this point maybe unnecessary and costly. Had...

Now again couples of days later I was putting gas on the car went finish the car wouldn't start like if no electricity wiered . Everything again reset I am terrified that is a electrical problem.

After the engine was replaced we are still having electrical and engine issues and dealers in Atlanta area will not accept engine repairs. The car will not start consistently and most dangerous if we use our bights (lights) for just a second even, the car will shut down and restart when the bights are released. This was in stop and go traffic on the highway The radio will stop and do a reset while driving for no reason this has happened on multiple occasions but the bright on day reported below

Subsequently following an engine replacement due to recall, there is now an electrical issue which has caused something to burn or possibly start fire as there is a burning smell from the hood and heat coming from under the hood into the car's cabin from the dashboard area and the drivers seat bottom is very hot. The heat increases rapidly inside the car from the engine, whenever it is on and running or on and idle. This is obvious how my life was at risk as every time i put the key in ignition, my life was at risk of fire or explosion or worse while driving. Car also sputters or stays idle when trying to quickly accelerate and this happens at random. The following list is more (minor) electrical malfunctions that have gradually become noticeable as I was using the vehicle: Cigarette light/phone charger power outlet does not stay...

The 2017 Hyundai Tuscan dual clutch transmission is seizing and unable accurate above 40 -45 mph. It is also unable to engage into reverse. It will shift into reverse, however will not move even when one places their foot on the gas pedal. The Hyundai Tucson seized while driving and I was almost hit in traffic. The dealerships in the Austin area have not been helpful as the closest they state they could look at it is November or December 2022 for a diagnostic and they are not willing to honor the powertrain warranty. After doing some research it seems a commen issue among Tuscan owners and is very similar to the issue Hyundai had with recall # 149 as related to the 2016 model. The vehicle is hazardous and unsafe to drive. The vehicle is putting the safety of myself and others at risk. There was no warning what...

The driver side passenger door will not open with pulling on the door handle multiple times, about 10+ tries with a lot of force to get the door open. This is not a lubrication issue, I have lubricated the locking mechanism and is hasn't helped at all. Imagine if the car rolled over and was on fire and this door wont open, its terrifying to think. There are no warning lights, the only way I found out that this was a widespread issue was on a car forum. I imagine that this is happening to many others, but they are not reporting it. Just to be clear, this isn't a door lock actuator issue, the locks are unlocking and locking just fine, there is a fatal flaw with the latching mechanism.

I took in my 2017 Hyundai Tuscon after the engine had stalled while driving. While in the shop, the engine was replaced which was part of a recall (Campaign 209) and also recalls 195 and 966 was addressed. After the repairs and driving home from the dealership, the engine and air conditioning started making weird noises and the following warning lights went on: ABS, power steering, and electronic stability control. When this happened, steering became difficult. We brought the car in the shop, but they denied there was any problem. Within two days after brining the car back to the dealership, the same problem occurred. And now the car will not even turn on.

I purchased my 2017 Tucson in 2020. It was the first car I’ve ever owned. I do not know much about cars but I noticed that there was some hesitation in acceleration and the engine was loud. Sometimes I would hear soft knocking on colder days but nothing extreme. I was told that the acceleration hesitation and the loud engine are due to the turbo. Then on 4/27/2022, without any warning, my engine stalled while I was at a traffic light. More importantly, I had ZERO warning lamps or messages. No engine warning or oil light was illuminated. My engine suddenly stalled. I don't drive my car very far. Use is relatively light. On average I drive about 10-20 miles per day. No one was hurt but what if this had happened on the highway? I would have definitely been rear-ended and hurt. My car passed inspection on 09/10/21. But...

An update on my previous complaint is attached. My vehicle has now been with the Hyundai dealership for two weeks with no resolution. They've provided little to no communication about the issues, or progress. Additionally, they have not provided me with a loaner vehicle, so I am without a mode of transportation for two weeks.

Myself, like others I have seen report the issue. The door (for me driver side front) will not open from the outside latch after door is unlocked. Can only open door from inside latch.

The contact owns a 2017 Hyundai Tucson. The contact stated that while driving up a mountain at an undisclosed speed, the vehicle was making a knocking noise and then stalled.

I own a 2017 Hyundai Tucson. While trying to get my elderly Grandmother out of the backseat to her appointment the rear drivers side door failed and would not open. After multiple attempts trying to open from outside and inside my ninety year old Grandmother had to maneuver herself to get out of the other door. This is a safety issue and Hyundai needs to address it. I have spoke with multiple Hyundai owners whom have experienced the same problem. What if there was an emergency/fire and no access to an available door??? I’m unsure if my service warranty will cover it, I’m scheduled to have it replaced but of course Hyundai is out weeks for appointments. With growing concern and thousands with the same problem this needs to be addressed immediately!
