Transmission & Drivetrain complaints by model year
Campaign 9C2 was installed on this vehicle and the now the vehicle is a danger to drive. My wife refuses to drive it as it bucks and jerks as well as the gas mileage has decreased from 35 highway to 28 highway. The fuel trims are way off on cold starts and the transmission now searches for the correct gear. Shifting back and forth. Just a slight touch of the accelerator and the car seems to jump forward which makes stop and go driving almost impossible.
NHTSA complaint #11746463 — an unverified report by a vehicle owner.
Following the completion of an official emissions recall software upgrade at Fitzgerald Auto Mall Countryside, Clearwater Florida, my 2017 Hyundai Santa Fe Sport (52,000 miles) now suffers from a severe loss of motive power and erratic transmission shifting/jerking during cold starts throughout day. The vehicle continues to hesitate during cold starts, making it impossible to safely accelerate from a stop into incoming traffic. I returned to dealership on 5/29/26 to address continued driving issues. The servicing dealership states they don't have a software fix and offer no mechanical fix. The dealership states they received an internal memo from Hyundai Corporate which instructed the dealership to tell affected owners to idle the vehicle for 1-3 minutes before driving to allow system adjustments. Forcing a consumer to wait out a dangerous powertrain defect in a running vehicle to avoid a roadway acceleration/loss accident is an unacceptable safety hazard. The manufacturers recall update has actively compromised the safe operation and motive control of this vehicle.
NHTSA complaint #11743387 — an unverified report by a vehicle owner.
2018 Hyundai Santa Fe Sport. Purchased January 2026 took to Oxmoor Hyundai Service Center March 2026. February 2026 began using oil at a measured rate of 700 miles per tank of oil. Used 3 full tanks of oil within the month of February. Oil lights and engine lights on and off and flashing during this time. March 8, 2026, engine light flashed and then stayed on continuously. Engine shook and stuttered and made a loud noise. Engine stalled while I was driving at 35-40 miles per hour. I was able to continue driving to my home with the stuttering and stalling. The next morning I drove it to the Oxmoor Hyundai Service Center. I told relayed the timeline of all symptoms I had experienced over the 2 month lifetime of my ownership. They did not attempt to reproduce the issue. They only entered "shakes in reverse" as the customer provided issue on the intake information. Service Center performed diagnostic, found cylinder misfires on cylinder 2 and cylinder 4. Replaced spark plugs to resolve Cylinder 2. Cylinder 4 continued to misfire. Used Borescope and found broken valve. They did not address the scoring on the cylinder of the valve. Recommended engine replacement. Advised it would not be covered under a warranty because the rod did not break. The oil consumption was proven with documentation from multiple Valvoline visits and the vertical scoring was present on the cylinder with the broken valve in the borescope photo. The Service Center refused to do a Boring Clearance Test or any other test that would prove the engine should be covered under an extended warranty or class action settlement. It wasn't until I reviewed HMA documents uploaded to the BBB Arbitration, that I realized that the information I initially gave to the Service Center of all the symptoms with timelines had not been entered into the system for diagnostic review by Techline. Arbitrator denied my claim under the theta settlement because the rod had not broken yet, BUT she said my engine was defective.

When I received a recall letter in the mail and brought my vehicle into Route 60 Hyundai of Vero Beach. My vehicle was also apart of the Theta 2 issue class act litigation.
NHTSA complaint #11738905 — an unverified report by a vehicle owner.
As I would be driving down the road, most of the time when getting up to speeds of either 25-30mph or 55-60mph is when the dash board lights up check BSD detection system failure, then it will rev out rpm’s to 5,000-6,000 then lose power to accelerator. I also notice on the dash board where the panel for your selected gear displays is blank and doesn’t show whether you are in park,drive neutral, ECT. After this occurs I can not drive it any longer until I safely stop the car (most of the time on a busy highway or country road Highway where once this happens it becomes dangerous due to the power loss in the accelerator) and put it in park, I’ve tried to put the vehicle in park, once fully stopped, and try to put it back into drive but the shifter is locked into park and will not let me shift the vehicle, I then have to shut the vehicle completely off and open the driver door to get the backup power cut off as-well to have zero power to the vehicle. Once that is completed I then Re-Start the vehicle where it operates normally again, this situation happens at least twice a week if not 3-4. It sometimes has put my passengers and myself at risk of getting into accidents or struck by other vehicle on the road. my vehicle is still under a warranty through the dealership I purchased it from, but when I ask them about it they say that because there is no prompt on the dash once I get there that they cannot do anything about it, nor do they allegedly know why it’s happening, I’ve asked a few other mechanics I know and they say that they have seen this malfunction before with this vehicle and usually it is a transmission sensor? Or a transmission speed sensor issue? I then relay this message back to the dealer ship and they still act like they don’t know what it is, I truly believe that the dealership just doesn’t want to deal with the issue and I only have 2-3000 miles left under their warranty, I do enjoy the vehicle and respect Hyundai for their great customer service.

NHTSA complaint #11735718 — an unverified report by a vehicle owner.
While driving the vehicle at approximately at 55 MPH on a the 826, the engine suffered a sudden and catastrophic mechanical failure without warning. The vehicle lost all motive power in active traffic, creating an immediate safety hazard and nearly resulting in a rear-end collision. Upon inspection, it was determined that the engine assembly, which is a replacement unit provided by Hyundai under the Theta II Settlement, with less than 12,000 miles, suffered an internal breach. This breach allowed coolant to contaminate the lubrication system sort of a milky oil, which led to a connecting rod bearing seizure. Despite this being a repeat failure of a safety-recall component and the vehicle being covered under the Theta II Settlement Lifetime Warranty, Hyundai Motor America has denied the repair claim. I am reporting this as a safety defect because the sudden engine stall resulted in a loss of power-assisted steering and braking while the vehicle was in motion.
NHTSA complaint #11726371 — an unverified report by a vehicle owner.
Enterprise car sales sold me this vehicle when it had 3 open recalls on it. The vehicle itself was a problem from the beginning. When I took it in for it's first oil change the mechanic told me it had no oil in it. He said they sold me a car that is notorious for consuming oil and or seizing or blowing up. I had the engine replaced on this car already and I just took it in for it's first oil change and it was already consuming oil. I want a new car but enterprise is telling me this is my problem
NHTSA complaint #11726332 — an unverified report by a vehicle owner.
Car stuttered and would not rev past 2k rpm. Blinking check engine light appeared Code was for known connecting rod failure for all theta engines for our 2018 sante fe. Hyundai is trying to get out of covering the cost of repair or replacement even though this is a very well known issue and is covered under warranty.
NHTSA complaint #11717081 — an unverified report by a vehicle owner.
Component: Engine (Theta II 2.4L GDI) / connecting rod bearing-related failure risk with abnormal internal oil loss. The vehicle is available for inspection upon request (engine, oil level condition, diagnostic history, and dealer records). Safety risk: While driving on the highway (approx. 70 mph), the vehicle displayed a low oil warning, and I experienced concern for potential engine seizure/stalling and sudden loss of power, which could cause a crash. I reduced speed and sought service. This condition presents an ongoing safety risk because sudden engine failure can occur without adequate warning. Dealer confirmation: The problem was confirmed by a Hyundai dealer. After a routine oil change, the low oil warning appeared within ~1,700 miles. A Hyundai service center inspected the vehicle and documented the engine was approximately 3 quarts low with no external leaks, indicating internal loss/engine deterioration rather than a leak. Hyundai then required additional steps (combustion chamber cleaning and monitored mileage), and the abnormal internal oil loss condition persisted. Manufacturer inspection: The vehicle has been inspected by Hyundai dealerships, and Hyundai performed campaign-related actions, including KSDS/ECM update (T3G) and later knock sensor replacement. No police or insurance inspection. No crash or injury occurred. Warning lamps/symptoms prior to failure: Prior symptoms included a Check Engine Lamp with DTC P1326 (KSDS-related) documented by Hyundai service in 2025, followed by continued abnormal internal engine condition. The low oil warning occurred while the vehicle was in motion (highway speed). The issue remains unresolved, and I do not feel the vehicle is safe to operate due to seizure/stall risk. Additional: I reported this as a safety defect because similar Theta II engine issues are widely reported and can result in stalling, seizure, or engine fire. Hyundai denied engine replacement assistance despite the documented condition.
NHTSA complaint #11708993 — an unverified report by a vehicle owner.
I have maintained my car regularly. I use LOFSYNBLEND oil at 7500 mile intervals per car and oil manufacturer. At 70000 mile oil change the tech showed me that less than a quart of oil came out of the crankcase during the oil change. There were no visible leaks, no visible smoke coming out of the exhaust when I drove the car, and NO warning light. This was the first time that this issue was present to my knowledge. I am taking the vehicle to the dealer for an Official Oil Consumption Test.
NHTSA complaint #11707342 — an unverified report by a vehicle owner.
The engine seized up on the highway with no warning signs or alerts and lost all power to the vehicle putting family at risk on the highway speed. Mechanic confirmed engine seized and metal debris after draining oil. Oil changes are done on timely basis within 5000 miles. Most recent where synthetic oil used and was just at 5000 mark. There was no oil warning at all and regular oil change was scheduled for next day prior to event. Car purchased in 2017 used and this happened before shortly after purchase and engine replaced by Hyundai at that time.

I am writing to express my concern regarding an ongoing and persistent issue with excessive engine oil consumption in my 2015 Hyundai Santa Fe, Subject: Severe Oil Consumption Issue - 2015 Hyundai Santa Fe - VIN: [XXX] The vehicle consumes an alarming amount of oil, approximately 1 quart every 300 miles. This rate of consumption is far beyond what is considered normal and strongly suggests a serious mechanical or manufacturing defect. I have already taken the vehicle to a mechanic to diagnose and attempt to resolve this problem. Based on their professional advice, the following parts were recently replaced: 1.Engine Valve Cover Gasket 2.Turbo Charger Oil Line 3.Spark Plugs Unfortunately, despite these repairs, the issue of excessive oil consumption remains unresolved. The rate of oil loss remains consistent and dangerously high. This was first informed by a service center when I took the car for a random check. Then, after traveling 1,000 miles, the engine oil level dropped again. After that, I am keeping an eye on that. This level of oil consumption poses a significant risk to the engine's long-term health and reliability, and it is a major inconvenience and expense for me as the owner. I am deeply concerned that a major engine component may be failing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Owner: [XXX] VIN: [XXX] Vehicle: 2014 Hyundai Santa Fe Sport My daughter purchased this vehicle in April 2025 from a licensed Chrysler dealership. On [XXX], the engine suddenly seized while driving, without warning, and would not restart. This VIN was part of Recall 17V-226 (Hyundai Campaign 162). Dealer records show the recall was closed with inspection only (“engine inspection, oil, dipstick”), not an engine replacement. The failure matches the defect description of the recall (bearing wear from restricted oil flow). Hyundai is refusing to repair it, claiming sludge and “maintenance neglect,” despite my daughter only owning it for 5 months and having an oil change at Hyundai in May 2025. This engine failure proves the prior “inspection” remedy was ineffective. Hyundai is also denying coverage under the lifetime warranty extension (TXXI), which explicitly applies to subsequent owners for bearing failures. This is a serious safety issue. My daughter lost power in traffic, and the vehicle is still unrepaired. This complaint is being submitted on behalf of the registered owner, [XXX] , by her mother [XXX] , who is the primary contact.

2013 HYUNDAI SANTA FE SPORT TURBO. PAST/PRESENT SAFETY-SENSITIVE DEFECTS, NOTED OVER THE PAST SEVERAL YEARS: 1. One Confirmed Open Recall [CAMPAIGN #/NHTSA RECALL #—Recall 251 / 23V651000] (To Be Scheduled ASAP). 2. RPM/Propulsion Limp-mode Conditions: Vehicle periodically loses RPM READINGS on Dash and goes into the Propulsion sputtering/restricted-speed limp-mode hesitation condition. This condition may occasionally normalize by stopping, turning off engine and restarting. This intermittent RPM/Propulsion condition sometimes occurs, signified by a temporary sputtering/bucking while driving vehicle. ❓️CHECK STORED CODES ASAP...To Do. 3. Several times the car failed to accelerate predictably. For example, as when trying to accelerate up to highway speed from the on-ramp, leading to a fear of a near-miss, stalling and getting rear-ended. On such occasions, since attention is directed outside of the vehicle for safety, the state of the RPM READING on the dash has not been noted. ❓️CHECK STORED CODES ASAP...To Do.

Loud knocking sound. Vehicle in Limp Mode. Blinking CEL - Error code P1326 VIN - [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
NHTSA complaint #11681720 — an unverified report by a vehicle owner.
The engine was replaced under a recall related to an engine knock code. About two weeks later, the vehicle lost all power while driving. The dealership confirmed a failure in the high-pressure fuel line and that the turbo had failed at the same time. The same visit revealed oil leaks, and shortly after, the vehicle began emitting white and black smoke. Their technician stated the failures were due to “consequential damage from engine failure.” The problems have continued to return, and I’ve been told the vehicle is unsafe to drive. Hyundai is now refusing to fully cover the cost of repair, offering only 15% off, despite all of the damage being directly linked to the replacement engine. I transport children in this vehicle. My safety and theirs have been at risk multiple times because of these unresolved and ongoing failures.
