the door latches are no longer opening the doors from the inside of the vehicle. This started with the passenger rear and now is effecting the drivers door. The only way to get out of the vehicle is to crawl over the seat to get to a door that is still operational. No warnings, just doesn't open when you pull on the handle. Will be making an appointment with a local dealer/service dept but given the security concerns this is being reported here as well.

The contact owns a 2017 Hyundai Tucson. The contact stated that while starting the vehicle and driving at an undisclosed speed, there was an abnormally loud grumbling sound coming from the engine.

While driving my vehicle, the engine RPM suddenly revved very high, and the vehicle hesitated to accelerate. A warning messaged appeared stating "Transmission too hot stop safely." I was driving up a hill when this happened. I pulled over and turned the vehicle off for about two minutes. When I restarted the vehicle, the warning message disappeared even though the vehicle would not realistically have cooled down that quickly. The issue concerns me because it could create a dangerous situation in traffic if the vehicle loses power or hesitates to accelerate when pulling into traffic or climbing a hill. The problem has occurred without warning and does not leave and persistent warning lights afterwards. I am very scared to drive this car, especially when I have my child with me. If I need to move out of the way and someone is driving that is not paying attention, there will be an accident because of the hesitation and the non-movement when I accelerate. I am reporting this issue in case it is related to a defect with the transmission system in this vehicle.

On March 10, 2026, my 2017 Hyundai Tucson entered 'Limp Home Mode' while driving, a known safety defect that causes a sudden loss of engine power. Diagnostic testing confirmed error code P1326 (Knock Sensor Detection System - KSDS). Despite this vehicle being covered under the Theta II Engine Class Action Settlement (Recall 209), which provides a 15-year/150,000-mile extended warranty for this specific issue, the dealership (Jim Ellis Hyundai of Atlanta) is refusing to perform the warrantied repair. Instead, the dealership has provided an estimate (#XXX) attempting to charge me $816.22 for the knock sensor replacement. They are also withholding the full GDS diagnostic scan reports and freeze frame data despite multiple written requests. Furthermore, the dealership is threatening to charge daily storage fees while actively denying a mandated safety repair. This refusal to honor the settlement warranty leaves the vehicle in an unsafe, unrepaired condition. This vehicle is a subject of the In re: Hyundai and Kia Engine Litigation II settlement. The refusal of the dealership to perform the KSDS-related repair (P1326}) is a direct violation of the court-approved settlement terms and a failure to address a documented safety defect.

On my 2017 Hyundai Tucson, my steering wheel light is illuminated. I took it to the dealership and they said I need a new steering wheel collar. My Hyundai has about 98,000 miles.

This car has major oil consumption that affects the engine and catalytic converter. This can cause engine damage and stalls in driving that affect safety on the roads because the car doesn't accelerate properly. There were no warning signals to indicate this being a problem with the car, especially at purchase. This car will get an oil change and in less than a week, the oil is gone and bone dry.

The contact owns a 2017 Hyundai Tucson. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. Due to the failure, the vehicle was towed to a dealer, and the excessive oil consumption was confirmed. The contact was informed that the vehicle was included in NHTSA Campaign Number: 21V727000 (Engine), and the engine was replaced. The vehicle was repaired, and a family member retrieved the vehicle and drove it to the residence without failure. Several days later, the family member started the vehicle, and fuel started pouring out from underneath the vehicle. Due to the failure, the vehicle was towed back to the dealer and was diagnosed the vehicle with an O-ring failure inside the fuel injectors. The dealer repaired the O-ring, and the contact picked up the vehicle from the dealer. Soon after retrieving the vehicle, fuel started pouring out from under the vehicle at start-up. The vehicle was towed back to the dealer and remained with the dealer. The manufacturer was notified of the failure, and a claim was filed. The vehicle was not repaired. The failure mileage was approximately 68,000.

I purchased this car from drive time, and when told about a possible recall on the engine i asked about it. We were told that the issue had been resolved. Not even 10 minutes after driving it off the lot the engine started misfiring, we had done a test drive prior to purchasing this vehicle and nothing had popped up on the dash about any problems. We have been unable to get it looked at. I was not sure if a report should have been filed until now. i am unable to produce photos at this time

Purchased used via Carvana in Sept 2025, check engine light came on while driving it home indicating a pre-existing mechanical defect. We submitted the claim through Silver Rock (Carvana's warranty company) and brought to their approved mechanic. The recommended the following repairs, several that were denied by Carvana/SilverRock: spark plugs, alternator, serpentine belt, fuel injection service, electrical ignition coil. A month later check engine light illuminated again and through further diagnostics the mechanic found that 2 of the faulty spark plugs were an incorrect model/fit for our vehicle and reported that information which resulted in replacement being approved (a month after initial request). Fast forward to January 2026 we experienced the widely reported knocking noise while driving coming from the engine and had it towed. The damage is a thrown rod and damaged bearing, which is consistent with the current oil consumption litigation, requiring engine replacement. Our 2017 Tucson 1.6 L turbocharge is not included in the recall. Furthermore, Carfax report shows last oil change reported was 2023. Carvana confirms an oil change is part of their 150 point inspection before a sale, however unable to provide me with documentation and failed to report a record of the work to Carfax. There are many instances of negligence on Carvana's part from failure to provide record of maintenance, which is also failure to adhere to their standard policy, and declining recommended service directly from their approved mechanic, knowing that this vehicle could be impacted by the well known defects through Hyundai. We are requesting assistance with engine replacement meeting safety standards and ensuring consumer protection.

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.

2017 Hyundai Tucson SE vehicle mileage approx. 54,000 miles Was driving on a Highway doing approx. 65-70mph within 30 minutes of the 1hr and 1/2 drive I had lost complete POWER STEERING. Wheel stiffened up and was scary and difficult to lane change to a slower lane or attempt to pull over at 11:00PM due too safety and could not pull over for over an 1 hour until I was home safely. Had to hold the wheel tightly for an hour. It was very difficult to turn and enter my double wide driveway and took 3 times to get car straight enough and pull in without Power Steering. Turned vehicle off and I had looked into possible issues with the (EPS) Electric Power Steering and read possible loss of Power Steering check MDPS Fuse in vehicle Interior Fuse Panel for blown fuse and all was Fine with that Fuse.. Then checked MDPS Fuse Panel in engine compartment near battery and found no issue on the long circuit fuse for the MDPS. After researching 2017 Tucson EPS issues I ran a test by Turning Key on and turn Wheel all the way too Right and leave it there for a minute then turn wheel all the way too the Left and leave there for a minute ,then turn steering wheel till wheels are straight and turn key off. Then start car and see if Power Steering comes back when turning steering wheel in which it did but I'm still skeptical if that was the Fix. Hyundai Car dealership wants to charge me $250 too run tests and diagnostics with computer system. Why should I have to pay for this since there have been numerous recalls on 2017 Tucson and the failure rate on some of the Electronics and Safety features and Engine issues and was originally in for a New Paint job for the Recall. And I just received a notification for the Anti-Theft Ignition Cylinder Protector hardware too be installed Free of charge for the ignition and hardware to be added. I have read and seen MDPS assembly issues causing sudden loss of Steering Assist on many of the sites and on these internet Hyundai Blog complaints.

Engine is burning oil causing the catalytic converter to clog and fail. Hyundai dealership told me after I had the car towed to them for repair on 12/30/2025 that the catalytic converter had already been replaced before in March 2024. I had purchased the car from another dealership March 2025 and the catalytic converter replacement was not on the car fax. I was also I formed by the Hyandai dealership that my car has an extended warranty of 10 year/150,000 miles on the engine due to the known oil consumption issue. My car has 131,000 miles. I was told Hyandai will make it very difficult for engine replacement since I’m a second owner. There needs to be a recall immediately.

am submitting a safety complaint regarding my Hyundai vehicle due to repeated engine power loss (limp mode), excessive oil loss, and a denied engine recall replacement. I initially brought my vehicle to the dealership after experiencing engine power loss/limp mode, engine oil loss, and illuminated check engine warning lights. The dealership confirmed that my vehicle was covered under an engine recall and stated that the recall procedure was completed. As part of this process, the dealership performed an engine combustion-related service and charged me approximately $1,600. After this repair, I drove the vehicle for approximately 1,000 miles. When I returned the vehicle to the dealership, the vehicle entered limp mode on the same day it was brought in, and the check engine light was illuminated again. The dealership advised me that the vehicle had lost an excessive amount of engine oil during the 1,000-mile period. Due to the continued engine issues and oil loss, the dealership requested a full engine replacement under the recall. However, Hyundai denied the engine recall replacement request. The vehicle’s repeated loss of power, excessive oil consumption, and limp mode create a serious safety concern, especially while driving at normal road speeds. I am concerned that the recall remedy was ineffective and that the denial of an engine replacement places drivers at risk. I am requesting that NHTSA review this matter for potential safety defects and improper handling of a known engine recall issue.
