2014 Hyundai Santa FE problems

AIR BAGS

I request that NHTSA review what I believe is a misleading Hyundai warranty extension involving the Occupant Classification System (OCS/ODS), part of the air bag system. Around Mid May 2026, my air bag warning light began illuminating intermittently. I waited because I needed to save up the cash. Around June 2026, Hyundai mailed me a Warranty Extension Notice stating that if the air bag warning light came on, I should take the vehicle and the letter to a Hyundai dealer. The notice contains no exclusions or limitations. I was excited because my local repair shop said it would cost $800 to $2000 depending on the issue. Relying on Hyundai's written instructions, I took my vehicle to the dealer. I was told my repair not covered under the scope of the warranty and was charged over $900. I paid under protest because I felt it was a safety risk to continue driving with an air bag warning. Although my initial goal was to receive a full refund, my main concern is that owners may rely on Hyundai's notice, only to discover the repair is denied. Some may delay repairing an air bag system because of the unexpected cost, creating a potential safety risk. I have written Hyundai July 2026 requesting a full explanation as to why my repair was excluded or a full refund but to date I have not received a response. I ask NHTSA to review whether Hyundai's warranty notice adequately discloses its actual coverage and limitations. I have attached the warranty letter, which contains no exclusions, and my repair invoice.

NHTSA complaint #11755191 — an unverified report by a vehicle owner.

ENGINE

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.

ENGINE

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.

ENGINE

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.

ENGINE

My daughter owns a 2014 Hyundai Santa Fe GLS, which is currently experiencing internal engine failure and abnormal engine noise. These issues directly align with Hyundai’s notification regarding the extended warranty coverage for vehicles equipped with the 3.3L Lambda II GDI engine, which may experience abnormal engine noise or damage. Hyundai has acknowledged these concerns and extended warranty protection for engine repairs or replacement. The Hyundai Holler dealership in winter park Florida. recently inspected the vehicle and reported a critical failure requiring immediate attention. The recommended service included: Timing job (all CVVTs, intake, camshaft, chains, guides, tensioners) Both valve cover gaskets and RTV replacement ( This is the internal parts of the engine) The estimated repair cost was $6,723.92. This recommendation reflects the exact type of engine-related failure covered under Hyundai’s extended warranty for this VIN. It is both unreasonable and disappointing that my daughter was presented with such a significant repair estimate for a condition Hyundai has already committed to covering. For context, my husband is a certified technician, and we have carefully reviewed the inspection details. The diagnosis provided by Holler Hyundais service department is consistent with the warranty-covered issue. Therefore, this repair should rightfully be processed under Hyundai’s extended warranty program.I must also share that my daughter a single disabled mother of three with limited resources and income. The dealership’s approach in presenting her with an astronomical repair bill—without recognizing the warranty coverage—causes unnecessary stress and financial hardship Mr Jesse Cappiello Service consultant. Refuses to accept this as warranty, by stating the warranty is only for Rod bearing failure. When the warranty clearly states engine failure I have attached the warranty info for your review.

ENGINE

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.

STEERING

The vehicle is making a loud clunking noise in the steering column when driving down the road. It is veering all over the road and when I hit a bump it’s very bad. It’s difficult to keep in the lane. I brought it to my mechanic who said it was most likely the electronic steering motor assembly. He said he would not drive it in its current condition. Hyundai themselves said that it would be dangerous to operate. On the complaint website I was looking on there was around 50 complaints that have been reported to the NHTSA already and the website said it would also be very dangerous to drive.

EXTERIOR LIGHTING

The low beams on the 2014 and many other year Hyundai Sant fe models do not work properly. While you are driving at night the low beams do not light up enough or shine bright enough on the roadway so you can see and drive safely ... I even installed brand new bulbs , and nothing changed as far as the brightness . The headlight housings are clear and do not have any type of damage that would prevent the bulbs from providing plenty of light on the roads . This is very dangerous for anyone trying to drive these vehicles on any kind of roads at night time .

SERVICE BRAKES

The start of this journey to Wesley Chapel Hyundai service department were 4 or 5 lights on the dashboard. I can’t remember what day I called to make the appointment-probably a week before the appointment as followed. I made appointment to take my Sante Fe Sport to Wesley Chapel for Monday 02/17/2025. The vehicle was not driven after the multiple lights came on the dashboard. That was their earliest appointment for service. On [XXX] the Santa Fe Sport was towed to Westly Chapel service department because a neighbor came over to tell us that the car lights were blinking. The car was not on. When they lifted the hood on the vehicle there was smoke and the smell of something burnt. They disconnected the battery, and the vehicle was towed by AAA to the Westley Chapel Hyundai. We live in a mobile home and park the car close to the kitchen window. This scared me. What could have been was losing my home to fire. Thankfully it didn’t happen. My question is how does an ABS ASSY go bad under 30,000 miles on a vehicle? And we are being told that some pump went bad first that caused the ABS ASSY to go bad. So also, I question how does a pump go bad under 30,000 miles on a vehicle? Should this ABS ASSY failure been covered under a recall? I have attached the Hyundai of Wesley Chapel invoice.
