2014 Hyundai Santa Fe: check engine light

Filed Jun 17, 2026 · Engine · TX

We are the original owner of a 2014 Hyundai Santa Fe. The vehicle is experiencing issues from internal engine oil consumption caused by a manufacturing defect in the GDI powertrain. In 2023, while driving under normal operating conditions, the vehicle began severely jerking, shuddering and hesitating during acceleration. This hesitation and sudden drop in power creates a severe and immediate traffic hazard, as the vehicle loses acceleration capabilities unpredictably while driving, merging, entering a highway or crossing intersections. I have since experience low oil volume due to this systemic oil consumption. On April 7, 2023 while I was under the 100,000 mile factory warranty (at 99,644), the issues were reported to the dealership but they found no issues. Since then the engine light come up regularly and we must add or change oil soon. On June 15, 2026 we took it back with the same issue and we have been told after checking it and filling it up we must repeat the process from 2023, drive it for 1000 miles without changing or adding oil, even if it dries up. This will create a safety hazard not only for the public but for my family. Now we are told the engine needs to be replaced but since we're out of warranty, we must pay $21,000. We were under warranty when we reported the issue and they purposedly led us out knowing the issues were happening to other Sonata and Santa Fe models. Now we are left with a dangerous vehicle which we cannot in good faith sell to any other family.

My car was in shop for Smog inspection and failed. Mechanic told me that the most likely reason was that the engine has issues related to failing crankshaft position sensor which triggered the check engine light. He further explained that the engine with this condition will have abnormal oil consumption. My experience is that is exactly what I wondered. No smoke in the exhaust, no oil leaks under the hood and no oil on the parking space at home nor work. Mechanic recommended I take the car to Hyundai dealer in Folsom. The service department there diagnosed my car and did not find fault with crankshaft position sensor but did find that there is a problem with timing mechanisms. They also said that the engine has difficulty starting, which I never experienced in over 50,000 I have driven it, save the time of battery replacement about 2 years ago. I decided to take my car back to my mechanic where he diagnosed it with timing issues. The abnormal engine noise was accounted for as a link to timing. In the interim I drive a rental at the rate of about $65.00 /day. I m in a quandary; if my mechanic repairs the timing issues, which may not be under warranty, does that invalidate the existing engine warranty? If I can get the warranty to cover the ongoing issues, we can save ourselves wasting time and money. If safety concerns are a priority, which is not, then we cannot sacrifice safety in the interest of celerity. In the meantime, my family are in the crossroads and I cannot accept that.

My engine failed and was diagnosed as needing to rebuilt or replaced by the dealership. During the pandemic it was hard to get parts so they rebuilt it. At first it was missed diagnosed because it was a 3.3l V6 and only the 4 cylinder engines were on recall. I had check engine lights on all the time. I paid for repairs that only masked the problem for a short time. It was such a problem I had to get a waiver to register my vehicle. After having more problems with my engine. Hyundai of Kennesaw confirmed my engine needed to be replaced they actually requested Corporate to approve an engine replacement for my vehicle in 2021. It was denied. So I paid for the rebuild. In August of 2025 i sent a letter extending the warranty which covered my vehicle engine rebuild. Hyundai denied that claim Jan 2026.

I was driving my daughters to school and the vehicle made a loud squeal and a subsequently a continuous clicking noise. I did not have any warning of the vehicle malfunctioning. There was no check engine light, no loss of power, or anything related to an impending failure. Upon this happening I was able to quickly get the vehicle moved as I was in the middle of the road with people around and lucking was not hit as I immediately stopped. I was close to home and was able to get the vehicle back to our home. Upon speaking with a Hyundai dealership they made me aware of a “silent recall” on many motors within the Hyundai failure due to internal failures. The vehicle was towed to the dealership and inspected and confirmed to have been linked to the engine failure. Hyundai is now stating that due to me being the second owner of the vehicle I am not apt to the extended warranty and there is no notice on any of the public facing knowledge to any of this information. I have gone through almost 2.5 months of back and forth with Hyundai case managers & the Attorney general.

I have been notified that I am in need of a new engine due to possible complete engine failure which is on the near horizon. I have the Lambda II V6 3.3L engine. It is knocking, making noises, hesitates to go, feels like it will stall out at all speeds, and is scaring me terribly. My certified local mechanic replaced a part for failed emissions, which cost almost $900. However the check engine light came back on. They stated I must go to Hyundai because they did not believe they could fix the car as it required a new engine. I took it to my Hyundai dealer, where my contact stated yes it should be covered as it was having the issues as have been identified with this engine. He later came back and stated his managers would not let him put through the claim, and said my estimate was now a whole new timing system at a cost of $4600. My car has less than 83,000 miles on it. My previous Hyundai is still running at 200,000 miles, so yes, I take good care of my vehicles. This is an early equipment failure on the part of Hyundai and Kia that they are now owning up to. I drive on busy 4 lane local roads, and I am afraid of this engine failure. Also, when I did take my Hyundai into the dealership, they did not have the ABS part needed for the recall. I was told it would be in within a couple of days. I have not been contacted back by them if it is in and to schedule me an appt. This is a huge failure in itself! I did make a claim to Hyundai Customer Care, that stated it was out of warranty. Today, I have my car at a 3rd automotive mechanic in the area to get a 3rd opinion. He has a minor timing issue code P0018 that emissions still kicked out once I finally got it passed. I am waiting to hear what he has to say regarding my engine with no beforehand knowledge of what I know so far. If my car catches fire or breaks down or seizes up on a busy road, I don't think that will go safely at all. I am very concerned for my safety and that of others.

My 2014 Hyundai Sonata is subject to the recall campaign for the 2.0L and 2.4L Gasoline Direct Injection (GDI) engines. Since June 24, 2024, the vehicle has exhibited multiple issues: 1. Check Engine Light: The check engine light is continuously on and blinking, signaling that the vehicle is unsafe to drive. Diagnostic codes retrieved include P0140 (O2 Circuit), P0172 (System Too Rich), and P0126 (Knock Sensor Circuit). While the P0126 code pertains to the knock sensor, there has been no definitive diagnosis to determine if the issue is isolated to the sensor or indicative of a deeper engine problem. 2. Engine Power Issue: The car experiences jolts and kicks back during acceleration, along with intermittent lack of power. Furthermore, an independent mechanic performed some tests on the engine, determining that it runs too rich. After the second white smoke through exhaust incident, the vehicle struggles, and often does not reach, 60 MPH; aligning with "Reduced power and/or hesitation" (case #2) in the recall campaign. 3. Exhaust Smoke: On two separate occasions, within a month, white smoke has been observed exiting the exhaust. Engine oil has been below 3/5 empty each time. No oil leak found; must be exiting through exhaust. Despite qualifying for the recall, the Hyundai Colorado Springs dealer has refused to inspect or replace the engine as required. These ongoing issues pose significant safety risks, including the potential for unexpected engine failure and loss of power while driving.

On [XXX] I was driving down a busy 4-lane in Los Angeles and my engine suddenly died. There were no warning signs like indicator lights or warning noises. It was traumatic and frightening and I thought I was going to be struck by a car or truck. I had little control over the car-it would not accelerate to get out of the road lane. I was coasting, stopped half toward the side of the road but still sticking out in the road lane and was terrified I'd get hit by another vehicle from my back driver's corner. Cars and trucks that were traveling at normal speed were trying to avoid a collision with me and swerving around me, putting myself and others at risk for serious injury or death. I had had all the systems updated 2 years ago at a HMA, Hyundai dealership as I was directed, which included the KSDS (Knock Sensor Detection System). Dealer said it was to warn me of possible engine noise and issues. I never got any warning. I was NEVER told by anyone including Hyundai or any regulatory agency that the engine could suddenly fail as I'm driving the car OR I WOULD NOT HAVE BEEN DRIVING IT! There were never any warnings at that time or any time that anything was wrong with the vehicle. The car was towed to a Hyundai dealership and they diagnosed the problem on 8/28/2024 as a failed engine bearings clearance test at 63Kmiles. I kept all maintenance records, all done timely and properly with full synthetic oil. The components were assessed by the Hyundai dealership in communication and with guidance through HMA, Hyundai Technical /Techline confirmed failed engine bearings clearance test. My engine was not making any noises beforehand at all, and no engine warning light or sounds gave any warnings to be cautious or do anything other than drive normally. I was told I need an engine replacement. A Prior Approval for the engine replacement was started on 8/28/24 and sent to HMA, Hyundai. 9/17/2024, I still don't have engine replacement, dealer refuses to give records.

Engine was replaced in Feb. 2020 as part of the 162 engine recall. Car engine completely shuts down while driving and cannot be restarted for 20 or so minutes. This leaves me stuck in traffic with no ability to move the car. The new engine only has 40,000 miles on it. Dealership first said it was an issue with the engine and valves but when I wanted them to pay, they said the car is fine and passes all inspections. The check oil light and engine light come on when the engine stops, but they are not on prior to the engine stalling. I have made three visits regarding this - 1 to my personal mechanic and two to the Hyundai dealership. I filmed a video of the stall but it is too long to upload.

On [XXX] I purchased a 2014 Hyundai Santa Fe Sport from an auto dealer in Wichita, Kansas. When I bought the car, On [XXX], my car started making a funny noise and the engine light came on and then it quit running and would not restart. I coasted to a back street and then got a ride home. I had it towed home and then purchased a new battery, thinking that might be the issue; but the new battery didn’t start my car. I called my dealership, as my car has a limited warranty on the engine and other parts for 24 months or 24,000 miles. Whichever comes first. At this time, I only had put 8,311 miles on the car; and had only owned it for 8 months. The dealership had my car towed to the mechanic they use. They determined that the engine had locked up. I received a call from the dealer stating they found out there was a recall on the engine through Hyundai; and stated that they have been in contact with a Hyundai dealership to have my car towed there. I contacted the Hyundai dealership and was informed they do not have a loaner car. I was paying for Lyft rides to work and getting rides by family home during this time. I received a call from the Hyundai dealership stating my car had been approved for a new motor to be installed; but it would take 3 to 4 weeks before it is shipped; and they still do not have a loaner car. I then rented a car from Enterprise on 5/11/24 for a week. On 5/15/24 I got a call from the Hyundai dealership stating my car would be ready on 5/16/24. I asked if the motor had been shipped in, and was told yes (which seemed odd since he had said a few days ago that it would take 3 to 4 weeks). I got a call on 5/16/24 that my car was ready. I went in to pick up my car and drove it a couple of days; and oil ran out. Dealership picked it up, supposedly fixed it; and now the oil light keeps coming on. I don't believe I got a new engine; and I am paying a lot of money for a salvage valued car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
