The engine in this 2016 Hyundai Tucson has experienced progressive failure symptoms consistent with the known rod bearing defect covered under Hyundai's engine warranty extension campaign. Symptoms include: excessive oil consumption requiring frequent top-offs over several months, severely degraded acceleration, failure to upshift under load, and an audible metallic crunching noise occurring around 4,000 RPM. A knock sensor fault code (P1326) was previously triggered (on 2/16/26), confirmed by a mechanic (on 2/17/26), and cleared. The dealer was visited (on 2/17/26) and refused to perform the campaign repair, stating no active code was present at that time. The vehicle is available for inspection. The problem has not been confirmed by the dealer despite a visit; the dealer declined to act citing absence of an active code. The vehicle has not been inspected by police or insurance. Warning symptoms include the prior knock sensor code, oil consumption, loss of power, and the current mechanical noise. Symptoms first appeared several months ago and have progressively worsened. The dealer's refusal to act under the existing campaign despite documented symptoms has left this vehicle in a dangerous condition on public roads.

Excessive oil consumption caused engine failure on December 17, 2025. My truck stopped and I was stranded on Highway I55 South for 4 hours. Hyundai and the Extended warranty has denied fixing my truck. It is still at [XXX] Hyundai as of today. Hyundai’s failure to properly diagnose or repair this issue when it was first reported under warranty has caused financial burden, diminished vehicle value, loss of use and inconvenience, and emotional distress and stress. This is a legitimate safety concern. I am demanding resolution of an ongoing excessive oil consumption defect in my 2016 Hyundai vehicle. This defect began while the vehicle was under warranty and has continued despite proper maintenance and compliance with Hyundai’s service requirements. I expect Hyundai to honor its legal and contractual obligations without further delay. Please contact [XXX] [XXX] Hyundai) @ [XXX] for details regarding repairs, oil consumption tests, etc. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing this complaint regarding my 2016 Hyundai Tucson due to excessive oil consumption. The vehicle burns oil at an abnormal rate, requiring me to add approximately one quart of engine oil every one to two weeks, even though the vehicle is driven very infrequently. This condition poses a serious safety risk because the engine could run low or completely out of oil while the vehicle is in operation, potentially causing sudden engine failure. This vehicle is used to transport my family, including children, which puts their safety at risk. I have taken the vehicle to Hyundai dealerships multiple times for full ispection , but no defect, warning, or solution was ever identified or communicated to me. There have been no warning lights or messages on the dashboard to alert me of low oil levels or engine problems, increasing the risk of failure without warning. The problem is ongoing and repeatable, and the vehicle and engine are available for inspection upon request.

There is a major problem with certain year Hyundai vehicles from 2016-2021 with the engine burning oil and clogging up the exhaust. My moms vehicle has been at dealership for evaluation and combustion cleaning multiple times and the problem still continues. There has been times where she is driving car and it starts to bog down and loose power which is a safety issue especially if on highway. The vehicle is burning oil, occasionally have to add oil. The engine light does come on at times. The car has been at dealership for recommended oil consumption test at every 1000 miles and has not passed. Combustion cleaning done each time and sent on way. Called and made complaint with Hyundai corporate and and got no where. The tech department at Hyundai factory gave dealership recommendations to do which were completed and still having same issue. The factory was only willing to cover 70% off the cost of new catalytic convertor and my mom to be responsible for remaining balance. Hyundai claimed that the convertor was out of warranty 8 years/80,000 miles even though this has been going on for past 2 years. This is not a problem caused by consumer but an issue with factory. Hyundai not living up to there 10 year/100,000 mile warranty as they advertise. There are facebook groups with people having same problems as we are with dealership not really doing anything other than combustion cleaning as advised by factory and corporate not doing anything either. I believe this is a major safety/defect issue with engines in these Hyundai Vehicles . What happens when someone is on the highway and the vehicle bogs down and another vehicle comes from behind and slams into you?

My 2016 Hyundai Tucson experienced engine failure consistent with known Hyundai engine defects. After reporting multiple battery outages, rapid oil consumption, and limited acceleration ability, outstanding warranties were checked and updated. However, the issues persisted, and the engine failed suddenly while I was driving. Hyundai denied warranty coverage without proof of the issues being unrelated to the warranty. This presents a serious safety hazard due to unexpected engine failure.

While driving under normal conditions, my engine experienced a sudden and catastrophic failure. The check-engine light illuminated, the vehicle began shaking violently, and I was forced to pull over immediately due to safety concerns. There was no prior warning and no oil pressure or oil warning light activated at any time before or during the failure. After stopping safely, I checked the oil level and found it lower than expected. I added oil as a precaution, but the condition did not improve and the vehicle became inoperable and required towing. The engine assembly remains intact and available for inspection upon request. This failure posed a serious safety risk, as the loss of engine function occurred without warning while the vehicle was in motion, creating the risk of stalling or loss of control. The vehicle was inspected by an authorized Hyundai dealership. Hyundai Motor America denied warranty and goodwill assistance, citing mileage and alleged insufficient maintenance documentation, despite the vehicle being within the 10-year powertrain period and despite the nature of the failure. Routine maintenance was performed throughout ownership; however, some historical service records are unavailable due to the age of the vehicle and changes in service locations over time. Multiple facilities no longer retain records from that period. Notably, no oil warning indicators never activated, which raises concern regarding the failure mechanism. Hyundai has acknowledged widespread engine issues in this engine family involving oil consumption, bearing failure, and sudden engine seizure. The symptoms and progression of this failure closely align with those known defect patterns. This complaint is submitted to document a sudden engine failure presenting a clear safety concern and to assist in identifying potential defect trends. This car has undergone previous engine repair, AC condenser and entire turbo by their service department previously 2022 & 2024 respectively.

Brought vehicle in on 07/10/25 to dealership with very low oil, it was determined vehicle was burning oil and combustion cleaning was recommended. Hyundai Corp. denied claim due to 2nd owner. We are not 2nd owner had to transfer title upon my father's death, vehicle owned by family. Hyundai then approved claim and combustion cleaning was done. We were then told by dealership to bring in vehicle every 1000 to check oil. On 2nd 1000 check it was determined to be burning oil and needed engine replacement. Hyundai Corp. denied claim this time stating gross maintenance neglect from 01/2018-06/2019 period but only 3084 miles were put on between oil change. This was not brought up during combustion denial. Also Hyundai stating out of warranty which expired 08/24/25 but issues started in 07/2025. I have asked Hyundai Case Manager to provide written proof in owner's manual where it shows we did not maintain vehicle in accordance to manual.

My 2016 Hyundai Tucson has a severe engine defect that causes excessive oil consumption and poses a safety risk while driving. It constantly throws the P1326 engine issue, which is the knock sensor.The issue is not due to any misuse or neglect on my part. The vehicle consumes approximately one quart of oil per week, and I have been advised by two different Hyundai dealerships not to invest any money into repairs because the engine should be replaced under Hyundai’s extended engine warranty (15 years/150,000 miles).Despite multiple attempts to get the issue resolved over the past year, Hyundai continues to deny the engine replacement, leaving me with no resolution and forcing me to drive an unsafe vehicle.The engine burns an excessive amount of oil and needs frequent refilling to prevent damage.The vehicle has stalled and runs rough at times, creating a safety concern.Both Hyundai dealerships I’ve visited confirmed that this is a known issue and advised me not to spend money on repairs since the engine qualifies for replacement under the extended warranty.Hyundai corporate continues to deny coverage and has not repaired or replaced the engine despite the clear warranty terms.The issue has persisted for nearly a year, and the vehicle continues to deteriorate.I believe this defect poses a serious safety hazard because the engine can fail without warning while driving. The excessive oil consumption also increases the risk of engine seizure, stalling, or fire. I am currently forced to operate the vehicle in unsafe conditions due to Hyundai’s inaction. I am requesting that the federal safety agency investigate this ongoing engine defect and Hyundai’s repeated denial of warranty coverage for affected Tucson models. Owners should not be forced to drive unsafe vehicles or pay for repairs that should be covered under Hyundai’s extended
