2016 Hyundai Tucson

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 NHTSA 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

Oil consumption is uneven, unpredictable, and has been a problem for at least 30,000 miles and since 2020. The car has ~74k miles on it and I carry a case of oil in the trunk. A couple years ago our catalytic converter clogged (I suspect from burning oil) and we were stuck on the roadside. Dealer replaced the catalytic converter under the power train warranty, but has not addressed the oil beyond a few consumption tests. They say it's "within normal parameters" but last night at a rest stop I had to add oil AGAIN. I feel like they're trying to wait until the warranty is up and then tell me it's not their problem.

My Tucson has been using an absurd amount of oil for the past 30,000 plus miles i had it in the shop for repairs for the exhaust/ turbo leaking due to broken stud bolt that finally was covered under warranty. But did nothing for the burning of oil. No oil leaks. It used a quart for every 500 miles. Now no warranty left i have a cylinder #1 misfire and have replaced sparkplug and will not come out of limp mode. Within a mile of driving the plug is oil fouled and goes back into limp mode. Probably will get no help from Hyundai to rebuild/ replacement of the motor.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving 75 MPH, the vehicle inadvertently lost motive power and was unable to accelerate above 35 MPH, prompting the contact to discontinue driving the vehicle. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed failures with the engine knock sensor and catalytic converter. The contact was informed that the vehicle was consuming an abnormal amount of engine oil. The vehicle was repaired. The manufacturer was notified of the failure, a case was opened, and the contact was provided with Goodwill assistance. The failure mileage was 70,000.

I bought this car with 85,000 miles on it and at 94,000 miles i began hearing a knocking sound in the engine, even with completing the first two oil change intervals within my ownership. no check engine light or warning signs came on, even with the knock sensor update. the engines performance declined immensly, acting as if it was going to seize, and burning through 1qt oil/500 miles with no leaks. i had to continuously buy oil to keep the oil tank full, as no dealerships near me had any availability for 3 months from the time i called, to the time i got into an appointment. i took the vehicle to the dealership to have the engine replaced under class action warranty. the dealership took 4 months to replace the engine, the first 2 denying approval until it was inevitably approved. during those 2 months i was not provided with a loaner car, and due to my age i was unable to rent a car. i still had to continue to pay a car payment and insurance on a car that was undriveable. hyundai cooperate would go 5/14 days at a time without contacting me, even with me calling everyday to try and get an update. there was not any clarity, communication, or updates on the process. once my engine was replaced my catalytic converter had clogged due to the pervious oil burning issue prior to the engine replacement. hyundai told me the engine and exhaust system have nothing to do with each other, and the only thing they could do was have me replace the part with an oem part (a 5k replacement) and we could “file for reimbursement” but there’s no guarantee i would be reimbursed. i have been put out of thousands of dollars and the ability to drive my car for 6+ months due to hyundais negligence of this known issue. i can not get out of my loan as i owe on it more than the car is worth so i am stuck with a car i don’t feel safe in, and has continuous issues that compromise safety. this company needs to be seriously looked into and held accountable.

While driving, on multiple occasions all warning lights will come on and the car will start to lose power. The headlights constantly go off and come back on randomly. Turn the blinker on and the rear window wipers intermittently come on. The vehicle has been towed to the dealership so many times and we either get “can’t duplicate” or needs oil change, which had just been done. Now we are being told that we need a second engine replacement. Unfortunately this time it will not be covered by warranty. We have reached out to Hyundaii Motors 3 times and the BBB Auto but they stand behind it not qualifying for the Lemon Law. Hyundai should have some obligation as all these issues are “known issues” just not recalls.The 2016 Hyundai Tucson is not a safe vehicle.
