2017 Hyundai Santa Fe Sport

At approximately 65,000 miles the car started using excessive amounts of oil in the crankcase. I visited the local Hyundai dealer who changed my oil and began monitoring the condition. I was instsructed to come back to the dealer every 1,000 miles for an oil top off and to report the consumption. On the third visit, the engine is now using approximately 2 quarts of oil in 1,000-1,100 miles. Extremely excessive. I inquired about a warranty claim but was denied since I was the second owner. Yet, Hyundai acknowledges problems with this engine and have established broader coverage for engine problems stemming from the rod bearing which includes coverage for the second owner. The high oil consumption underscores another problem with this horrible engine, and high oil consumption should be included in a recall and repairs.

My ABS and Traction Control lights keep going off, intermittently. They have been doing it for several years.It can be for hours or for days. I took a video of it happening a couple years ago, and photos, also. More recently my speedometer has started jumping. I had the ABS recall performed when it was first implemented. When I've taken my vehicle to Hyundai (twice now specifically for this) they say they can see no codes and will do nothing. From what I have read on the ABS recall, this is what are the symptoms of it. I am under the impression that I have somehow gotten a defective part, even when they did the recall. The recall was that it could cause an engine fire. Today driving home, for a second, downhill, the oil light came on for a second-then went off. I came home and parked. My husband checked. He said there is no oil in the car. That, I imagine is part of the other engine issue this model has. But you would think the oil light would come on sooner and STAY on. He is going to get some oil and then take it to a shop when he gets off work. My main concern is getting the ABS/speedometer fixed as I believe it is from the first recall. The second issue-that is probably a Hyundai "recognized" issue. They just keep telling me nothing is wrong with the ABS/speedometer though. I have photos spanning several year, it falls in line with the recalled issue. Just replace the part already. The last date I went to Hyundai was Monday last week, so I'll put that as the incident date, as I was there for the ABS/speedometer. I had to drive an hour each way to see them twice now to be told they can't do anything. Today the oil light came on.

While driving on a highway in April 2025, my 2017 Hyundai Santa Fe Sport suddenly lost all power after approximately 10 minutes of normal driving. All dashboard warning lights illuminated, and both the accelerator and brake pedals became unresponsive. I was forced to stop the vehicle using the handbrake in the middle of a 65 mph highway, creating an extremely dangerous situation for myself and other drivers. Prior to this incident, the vehicle had displayed the P1326 knock sensor code multiple times over a 10-month period, each time accompanied by hesitation when accelerating. The knock sensor was replaced twice under used car warranty by Honda. Despite these interventions, the same code and symptoms recurred. The Hyundai dealership(Dec 2024 at Montgomery, Jan 2025 at Enterprise) repeatedly stated that there was “nothing wrong with the engine.” After the highway failure, the vehicle was inspected by a collision center and an independent mechanic. They confirmed that Cylinder 4 had no compression and diagnosed a burnt valve. Full engine replacement was recommended. Hyundai initially indicated that the engine might be covered under the extended warranty but later denied the claim, stating that the damage was due to a cylinder issue and can not check bearing failure. They also claimed it was too late to determine whether the bearing was the cause. This is not an isolated issue. Many Hyundai owners across the U.S. have reported identical symptoms—P1326 code, hesitation, cylinder compression loss, and ultimately engine failure—particularly in vehicles equipped with the Theta II engine. These failures often occur around or after 100,000 miles, despite regular maintenance. This ongoing and widespread cylinder-related engine failure presents a serious safety risk and must be addressed through manufacturer accountability, improved diagnostic standards, and proactive repair or recall efforts.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated while driving 70 MPH, the side view mirror displayed an amber signal light; however, when the sun was extremely bright, the contact was unable to see the amber light. There were no warning lights illuminated. The vehicle was taken to a dealer where the diagnosis was undetermined; however, the dealer informed the contact that the light could not be changed. The contact was informed the amber light could not be switched from amber to red. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

My 2017 Hyundai Santa Fe had a new engine installed at the dealership, Fred Beans Hyundai Flemington, NJ. I picked it up on [XXX] on [XXX] (and after 134 miles) my car's check engine light came on. I rerouted to dealership about 8 miles. Sitting outside service bay, I smelled smoke and then saw smoke coming out of vents. I then jumped out of car and the car became engulfed in flames and subsequently exploded. The day I picked it up, I pointed out to the service manager that they had not reattached everything to the car properly, sloppy workmanship. Best guess is that they did not attach a valve correctly.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated on the instrument panel. The contact later added 2 quarts of oil to the engine; however, not too long after adding the oil, the contact checked the dipstick, and the oil had been consumed. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was taken to the dealer to be serviced and the contact was informed that the engine oil was abnormally low. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 98,000.

Excessive Oil Consumption caused the PCV Sensor/Actuator (Exhaust Camshaft Timing Oil Control Valve) to fail. While the vehicle is still operable, the failure causes engine timing to change resulting unpredictable losses in power during acceleration, excessive fuel consumption, and incomplete combustion passing through the Catalytic Convertor posing a risk for future component failure. In the four months that the vehicle is operating in this condition, with its check engine light on, I have had two near collisions while attempting to merge into roundabouts and freeway entry. Fortunately, both were avoided. I no longer attempt freeway entry during rush hour. Two independent service repair shops did a computer diagnostic test and confirmed the problem with the PCV components. They suggested that the excessive oil condition be corrected first. Otherwise, any replacement components will continue to fail. Excessive oil consumption appears to be a chronic problem in the Hyundai 2.4 L engine. The engine and drivetrain is covered under a 10 year or 100,000 warranty. A year earlier the dealership performed a controlled test when the vehicle only had 60,941 miles, where the initial oil loss was 2.5 quarts per 1,000 miles. An Oil Chamber Combustion Clean, where solvents are used to remove excess carbon was performed. It temporarily reduced the oil consumption to .7 quarts per 1,000 miles. This is still requiring a replacement of about 2 Quarts of oil between routine oil changes in a 5 quart system. The dealership indicated that it passed. About 3 months later the oil consumption increased to 1.0 Quart per 1,000 miles and 8 months later the PCV components failed. If the dealership did the right thing and repaired the engine to eliminate oil consumption, everything would have been fine. I am still trying to get the dealership and Hyundai to honor their warranty. for excess oil consumption. With it the PCV components are also replaced and all is good.
