2019 Hyundai Santa Fe

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while driving approximately 45 MPH, the vehicle hesitated while accelerating with the accelerator pedal depressed and the RPM raised. The contact stated that the vehicle occasionally failed to start. No warning light was illuminated. Additionally, while driving at various speeds, the vehicle lost automotive power. The vehicle was taken to a local dealer, where it was diagnosed, and determined that there were metal shavings in the oil pan. Hyundai Eugene (89320 N Game Farm Rd, Eugene, OR 97408) was contacted; however, the failure was not identified. Upon further investigation, the Hyundai Blue Link App retrieved DTC associated with the Power Train EMS and Power Train TCU. The vehicle was not repaired due to the cost. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 87,000.

Since December my car has been burning oil at a fast rate. My husband has already had to add an additional 4 quarts since my last service 3000 miles ago. I have read and heard from others with a Santa Fe that they are having to replace their engines because of this. They are under warranty. Unfortunately I am not. I’ve already dealt with a white paint issue with Hyundai. I called couple weeks ago and was told someone would email me and they have not. I’m not sure where to turn now.

Complaint: Safety Defect - Engine Failure Risk (Stalling/Fire) My 2019 Hyundai Santa Fe has the defective Theta II 2.0L Turbo engine (G4KH), subject of class action In re: Hyundai and Kia Engine Litigation and multiple TSBs. The engine has a known manufacturing defect causing premature connecting rod bearing failure, leading to catastrophic engine seizure. SAFETY CONSEQUENCE: This defect presents a clear, unreasonable safety risk: Sudden Stalling: Engine can seize without warning while driving, causing loss of propulsion and power steering/brakes, leading to a crash. Engine Fire: Failed engines can leak oil onto hot components, causing fires. MANUFACTURER'S INADEQUATE REMEDY: Hyundai's "Knock Sensor Detection System" software update (Campaign 966) only attempts to detect failure moments before it happens. It does NOT fix the underlying mechanical defect. The engine remains a ticking time bomb. PERSONAL EXPERIENCE: My vehicle has suffered multiple related failures (turbocharger, fuel injectors) costing over $5,700, confirming the powertrain's deterioration. I fear driving it, especially with my teenage daughter. The defect is well-known, yet Hyundai's settlements fail to protect subsequent owners like myself, leaving unsafe vehicles on the road. REQUEST: I urge NHTSA to investigate the ongoing safety risk these engines pose to all owners, compel Hyundai to issue a true safety recall for a permanent repair (e.g., engine long-block replacement), and mandate clear disclosure of this defect to all used car buyers.

I was driving home Friday August 29th 2025 around 10:30 am on I-70 W when I began to have trouble accelerating my vehicle. There were vehicles trailing closely behind me so I increased pressure on the gas pedal. I would feel my car forcibly trying to compensate and the RPMs on the vehicle increased significantly. The check engine light then illuminated and the car stedily beagan to decelerate although RPMS were increasing and the force on the gas pedal was at its maximum. I could no longer get past 30 MPH. The cars behind me had to quickly change lanes behind me to avoid rear end collision and I finally pulled over to the shoulder of the highway but it was a very narrow shoulder so my safety and the safety of those driving around were compromised because they could have easily resulted in a high speed rear-end collision that could have been fatal and the location of my car on the shoulder was not safe and I could have been side-swipped waiting for a friend to come get me and for me to move my car off hat narrow shoulder. I was frantic and very emotionally distressed by this incident because all the maintenance on the car was up to date and there was no check engine light on in the car prior to this incident. The unexpected and decelleration and inability to compensate on the highway was very unsafe. I have taken my car to the delearship and they have yet to address my engine issues or the safety concerns. The rep actually laughed while I was recounting the events. I also called hagerstown police department to have a police officer come out to the breakdown site because I did not feel safe but my frined arrived before the police.

Vehicle is shuddering/jerking upon acceleration due to a defect in the 8 speed automatic transmission. This condition was reproduced by Hyundai of Plymouth, MA and documented on the repair order. Dealer states that a new transmission is required to fix this problem. Safety is at risk due to shuddering upon acceleration which causes hesitation in acceleration. My Hyundai Santa Fe is available for inspection. There should be a recall on this vehicle.

When accelerating the transmission slips. My mechanic said Hyundai has a memo saying they are making a new torque converter due to these problems, and I will need a new torque converter. The torque converter is on backorder and according to my mechanic, will not be available for many months; thus indicating there are many other folks with the same problem. This is very dangerous when accelerating, as the speed drops off due to the slippage, and can put me in a dangerous position if I need to accelerate to avoid a potential situation. It has also presented issues from a dead stop, pulling out into traffic, where the slippage puts me at risk. This has been going on for quite some time, and my mechanic has been doing what Hyundai memos instuct.

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle lost motive power while depressing the accelerator pedal, with the check engine warning light illuminated. The vehicle was taken to a dealer and the turbo was replaced. The contact stated that months later, the vehicle hesitated and jerked while depressing the accelerator pedal with the check engine warning light illuminated. The vehicle was taken back to the dealer where a part on the transmission was replaced; however, the failure returned, and the check engine warning light illuminated. The vehicle was taken back to the dealer and the contact was informed that the transmission needed to be replaced. The contact took the vehicle to an independent mechanic and had the transmission replaced. The contact stated that months later, the vehicle began to sputter with an abnormal knocking sound coming from the vehicle. The check engine warning light returned, and the vehicle was taken to the nearest dealer. The vehicle was diagnosed with engine failure. The vehicle was not repaired and remained with the dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.

Transmission: yes, available upon inspection I own a 2019 Hyundai Santa Fe. I have brought it in for repairs on the transmission a couple of times. The check engine light has come on but the computer was not displaying the problem. I am aware that this is not uncommon for the year, make, and model. Recently, I was driving my car on a high-speed highway when the transmission went out. While suppressing the gas, the transmission slipped and would not accelerate. As cars were passing me on either side, my car decelerated and cars behind me came close to rear-ending me. Again, this was at high speeds and put my safety in jeopardy. I was finally able to find a gap in the cars and able to get to the shoulder but not after several minutes of unsafe conditions. After this incident, I brought it back to the service center and the computer analysis did display that it is an internal transmission problem. The service center has inspected the transmission. Yes, the warning lamps were displaying, first about 8 months prior. As stated previously, the actual problem was not displaying. Attached document is previous work done for transmission due to incorrect computer diagnostics.

Upon going for an oil change at Express Lube in Newton , NJ I was advised that there are multiple widespread & ongoing problems with a crack that forms in the oil pan next to the drain/fill plug. My vehicle was diagnosed with that very problem. I believe a a recall to should be done by Hyundai to replace these oil pans. Thank you
