2013 Hyundai Santa Fe Sport: check engine light

Filed Nov 5, 2026 · Engine · TX · 1 injury

the federal safety agency SAFETY & CAMPAIGN NON-COMPLIANCE COMPLAINT (VIN: [XXX] | HYUNDAI CASE #XXX): On XXX, my 2013 Hyundai Santa Fe Sport 2.4L Theta II GDI (covered by Hyundai Warranty Extension TXXI Limited Lifetime Warranty under TSB 22-EM-001H-1 / the federal safety agency MC-10211673-0001 and Service Campaign T3G / the federal safety agency [XXX]) entered Engine Protection Mode (Limp Mode) with flashing Check Engine Light / DTC P1326 and a severe metallic connecting-rod bearing knock under 2,000 RPM. At 8:00 AM on XXX, I brought the vehicle to Huffines Hyundai Plano ([XXX]). Despite the federal safety agency ID [XXX] mandating an immediate Service Rental Car (SRC) or 3rd-party rental upon reception ("reimbursed regardless of PA's decision") and prohibiting diagnostic fees after Campaign 953/KSDS, the dealership refused a loaner, told me diagnosis would take a full week while I rent a car out of pocket, forced me to drive the unsafe vehicle in Limp Mode to take my disabled father to a medical appointment, and stranded us in the lobby for 7 hours (causing my father to miss scheduled prescriptions and failing to restore his disability placard). At 2:00 PM, the dealership claimed the vehicle "PASSED" the Bearing Clearance Test (BCT) without giving me the mandatory BCT printout or multi-point inspection sheet, cleared the P1326 code, performed a KSDS software update instead of inspecting the knocking engine, refused to record the mandatory STUI Engine Noise Video or submit a Warranty Prior Approval (PA), and tried to coerce me into signing a falsified Repair Order stating "CUSTOMER IS DECLINING DIAGNOSTICS." At 5:33 PM, HMA Executive Case Manager [XXX] ([XXX]) falsely stated in writing that TXXI is capped at 10 years/120,000 miles (confusing TXXC with TXXI), that T3G does not apply, and that passing BCT means "your rod bearings are in working order." CRITICAL HIGHWAY SAFETY FAILURE (RECORDED ON VIDEO): On the night of Wednesday, XXX — just hour INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORMAL VEHICLE SAFETY AND WARRANTY COMPLAINT Date: [XXX] From: [XXX] Vehicle: 2013 Hyundai Santa Fe Sport, 2.4L Theta II engine Mileage: Approximately 150,000 miles (exact current reading to be confirmed) Subject: Recurrent Check-Engine Warning Following Repeated Repairs; Request for Theta II Engine Investigation I am submitting this complaint to formally document recurring engine-related symptoms affecting my 2013 Hyundai Santa Fe Sport, and my repeated requests for investigation of a possible connection to the known Theta II engine defects and related warranty programs. On [XXX], the check-engine light illuminated again. Previously, on three separate occasions, the vehicle experienced a flashing check-engine light and a light ticking noise while idling. I was advised each time that the knock sensor was responsible, and the sensor was replaced. The vehicle returned to normal operation after those repairs, but similar symptoms subsequently recurred. While my vehicle was still below the 150,000-mile threshold, I repeatedly expressed concern that the symptoms could relate to the Theta II engine issue. During the most recent dealership visit, resulting in repairs on September 10, 2026, I emphasized that the recommended valve-cover gasket and spark-plug work might address a secondary issue without resolving the primary recurring problem. The check-engine light has now returned approximately five weeks after that repair. I am not claiming that a connecting-rod-bearing defect has been conclusively diagnosed. I am asking that the possibility be properly evaluated and that my earlier reports, repair attempts, and the mileage at which I first raised these concerns be preserved and considered when warranty eligibility is reviewed. I am sending this as a record of contact and communication.. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2013 Hyundai Santa Fe Sport is subject to Hyundai Recall 162 / the federal safety agency Recall 17V‑226, concerning premature connecting-rod-bearing wear that can cause engine knocking, engine failure, and loss of motive power. My vehicle developed engine knocking and a flashing check-engine light while I was driving. The vehicle is now at an authorized Hyundai dealership. Hyundai initially denied an engine replacement based on mileage. I escalated the matter to Hyundai Motor America Corporate Consumer Affairs. Hyundai has now confirmed in writing that, because my vehicle is more than eight years old and has more than 150,000 miles, Hyundai is applying the high-mileage provision of the Theta II settlement and will not replace the engine. Instead, Hyundai is offering either a repurchase or $2,000 in lieu of engine replacement. I understand that Hyundai is relying on the court-approved settlement. My concern is specifically whether Hyundai’s application of that settlement to my vehicle is consistent with the administration of Recall 162 and the federal safety-recall remedy, given that my vehicle is experiencing the engine failure that Recall 162 was designed to address. I am requesting the federal safety agency’s review of Hyundai’s handling of this safety-related recall matter.

Vehicle is a 2013 Hyundai Santa Fe Sport with the 2.4L Theta II GDI engine. A Hyundai dealer documented excessive oil consumption in December 2025 (3 quarts consumed over 1,703 miles during a dealer-administered oil consumption test; repair orders on file and available for inspection). On April 19, 2026, at 160,913 miles, following a highway drive, the engine developed a pronounced knock and vibration at low RPM and began stalling within seconds of idling in Park, with check engine and charging warning lamps illuminated. An engine that stalls at idle presents a safety hazard in traffic due to loss of power braking and steering assist. The vehicle was removed from service the same day, has not been driven since, and remains available for inspection. Knock Sensor Detection System software (Campaign 953) was installed and did not prevent the failure. Manufacturer has been notified in writing and consumer affairs cases are on file.

I noticed a Check Engine Light flashing on my dashboard while driving on May 27, 2026. The vehicle suddenly losing power is extremely unsafe for me and my family, and also others on the road. This is a repeated P1326 code which happened before in 2021 and 2024. Based on the receipts I have from the previous inspections from the dealer, the Bearing Clearance Test (BCT) was not done in 2024, but was performed in 2021. The knock sensor was replaced in 2024 and I was denied engine replacement. This is a repeat failure of the same condition under Hyundai Motors TSB T3G Theta II. Once again, my safety was at extreme risk as the engine lost its power suddenly. It could have easily lead to a crash. In 2024, Hyundai and the dealer declined an engine replacement despite me showing the safety concerns and my possible eligibility for an engine replacement for the underlying condition.

On [XXX] while entering the parking lot of my office, I noticed a blinking check engine light on the car's dashboard. I've never experienced this before so I called my husband. He asked me to use a diagnositic tool he kept in the car. I did and there was a code "P1326" when I pressed the key for more information it said something about the manufacturer. My husband told me to call the nearest dealer. I called Castle Hyundai in Downers Grove. I was instructed not to drive the care and have it towed to the dealership as soon as possible which I did. Castle Hyundai verified the P1326 code and fixed the knock sensor, changed the oil. I picked the car up on March 13. On [XXX], the flashing check engine light returned while driving home from work. Again, we used the diagnostic tool and again the code P1326 appeared. The car was towed back to Castle Hyundai. On Monday, I spoke with Christain Jones the service director because I hadn't heard anything about the car. He called later in the day and said that the car needed a new engine. He asked for records of my oil changes since purchasing the car in 2021. I emailed him three from 2022, 2023 and 2024, the four change was done by Castle on March 12 2026. I was told that he would send the the information to Hyundai regarding a new engine. However, he stated that he was not confident the company would approve the claim. This after, I received an email from Eric Marcum with Castle. The email stated that Hyundai denied the engine replacement due to "lack of maintenance". He wanted to know if we wanted an estimate on replacement of the engine. I responsed that I needed Hyundai's rejection in writing and I also wanted an estimate of the replacement. I attempted to contact Hyundai's Customer Care, however, their offices were closed until Monday. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
