My car has been burning oil for over a year. there is no leak. I have been putting three quarts in every 4 to 6 weeks. I have now replaced two coil packs and the spark plugs. my engine light is on because it said 3 and 4 was misfiring so i recently replaced those coil packs and now it said spark plug and i replaced it again as well. so the engine light coming on and what it says the problem is is wrong. now when i push the gas it is knocking or missing. not sure how to describe it. no one has looked at it other than a friend that is a mechanic and he says its probably the engine because this kind of car has these problems.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at various speeds, the vehicle hesitated while depressing the accelerator pedal. The contact stated that the oil light was flashing on the instrument panel while turning the steering wheel. The vehicle was taken to an independent mechanic where the contact was informed that the vehicle was consuming an excessive amount of oil. The vehicle was taken to a dealer for an oil consumption test and the oil was topped off. The contact was instructed to bring the vehicle back after 1,000 miles. Upon investigation, the contact discovered that the engine oil consumption failure was widely reported. The vehicle was taken back to the dealer as instructed, and the contact was informed that the engine had not consumed enough oil to be considered a defect. The contact was advised to purchase a factory-made oil filter from the dealer because the independent mechanic had not used the proper oil filter on the oil change. The contact stated that at the follow-up oil change, the independent mechanic used the factory oil filter; however, the failure persisted. The manufacturer was notified of the failure and the contact was informed that the vehicle was not under recall or warranty. The vehicle remained with the independent mechanic unrepaired. The failure mileage was approximately 98,000.

My vehicle began experiencing issues around 83,000 miles. The engine started burning oil, showed shuddering during acceleration, and there was a noticeable smell of gasoline inside the cabin. Eventually, the car wouldn’t start, so I had it towed to the dealership. The technicians confirmed it was running rough and behaving abnormally. The Hyundai dealership conducted a full inspection and diagnosed several issues. They replaced the spark plugs, performed a GDI-safe induction cleaning, replaced the coolant and brake fluids, completed a transmission fluid service, installed a new battery, carried out wheel alignments, and changed the cabin air filter. All of this work was completed in October 2024. However, in December 2024, I had to return to the dealership because the fuel smell inside the cabin persisted. Although they couldn’t find the source of the issue, the smell eventually disappeared after the visit. Following that, I was advised to check my oil every 3,000 miles due to the GDI engine's reputation for burning oil quickly. Despite this, the car began running rough again, and when I checked the oil, it was completely dry—well before reaching the 3,000-mile mark. I had to get another oil change sooner than expected. Unfortunately, the issue continued. I brought the vehicle back to the dealership for another inspection. They suggested starting a monitoring process where I would bring the car in every 1,000 miles to check the oil levels. After driving 1,000 miles, the oil level was just slightly above the low mark—still not normal for such a short distance. I urgently need assistance to move forward with the engine replacement process before my warranty expires. I am currently at 91,000 miles.

Car would not accelerate after getting on the interstate. Had to ease vehicle off exit ramp to side of road. Multiple engine lights on. Car would no longer start. Had independent mechanic shop evaluate as well as local Hyundai dealership. Both determined internal compression rod failure. Only solution is to replace engine. It is a 1.6L T for 2017 Tucson. The VIN for this car shows no engine recall but is the exact same issue that has resulted in Hyundai engine recall with the 2.0 vehicles.

Despite proper maintenance, at 100k miles the engine started knocking aggressively and the dealership advised me not to drive it or it would throw a rod in the very near future. It started burning oil around 80k miles. This is the Limited model with the gamma engine that was not included in the recalls of the other Tuscon engine, but seems to have the same problem.

The engine entered limp mode, lost oil pressure and began knocking. Vehicle was brought to a dealer where it remained for ~1 month. The dealer inspected the vehicle, and determined it to be a valve cover leak, which does not track given the issues. When picked up from the dealer, the engine seized shortly down the road. Upon my own inspection, it was found that the engine oil drain plug was missing. It is unclear if the dealer loosened the drain plug during their inspection, or if it fell out due to some other issue. In either case, the manufacturer and their representative (dealership) created a dangerous situation for the driver of that vehicle, which had to be pushed out of moving traffic during a busy time of day.

Within last oil change the engine had oil consumption and has a loud engine knocking sound. The upcoming oil change date had not been exceeded and/or miles had not been exceeded. The engine knock caused me to pull over immediately at a location on a highly traveled road and no shoulder or safe spot which was dangerous. Safety was a concern because I had to wait for a tow truck in cold winter weather. The local Hyundai dealership maintenance person said it was a known issue with that make and model and the repair wait time is 5 months because they don't have enough staff and cannot get parts. My tuscan just had an inspection at the last oil change on 10/22/2024. no report from Hyundai that the oil level was an issue or engine having problems. There not any warning lights or low level lights and/or noises until it suddenly happened.

NHTSA ODI 11638477

Engine knocking began around 132,000 miles and caused intermittent loss of power while driving. This caused me to slow down at random intervals while on the roadway becoming a hazard for other drivers. Engine light activated shortly before the symptoms began. No inspections done yet.

Greetings, I have had issues with the Hyundai Tucson 2017 I own for many months. Issues include among others an abnormal knocking noise from the engine, reduced engine power and/or hesitation, burning smell, oil leaking, and smoke coming out of the engine, misfires, and other issues. It happened many times on the highway and almost caused accidents and the last time it happened, the vehicle was towed, and recently the smoke coming from the engine forced me to pull over. I reported the issue to the dealer but they didn't recall or address the issue. The car has been maintained properly over time and now I fear for my life. It is totally unfair that about 100k of this brand have been recalled for the same issue, in my case it is just after I finished to pay in full the vehicle. I seek your support to have it addressed for safety

I was driving on [XXX] and the acceleration just started to drastically slow down. I was able to get to the shoulder where the car completely died and wouldn’t cut back on and I had it towed to South Bay Hyundai in Torrance. They said it’s engine failure but they haven’t completed the full inspection yet. I have been using Uber and need a car rental because I can’t afford to sustain this huge inconvenience indefinitely.

My transmission has failed fully. It cannot even reverse. I took my car into Hyundai several times to check on the issue and they said the same thing, that the transmission slipping is a standard issue for dual clutch. I told them over and over that this is different. I did some research as to how to have them cover it and have it changed but the dealership said nothings wrong. Fast forward and now my cars transmission is fully gone and it probably won’t be covered when I know that it should have been part of the recall ! Just this year I’ve spent $5000 on repairs for this vehicle and now I’m looking at another $5000 for only a 7 year old vehicle. If that does not constitute a lemon I don’t know what does.

The engine developed a knocking sound at 97,018 miles. When it was checked, it did not have any oil in it at all, regardless of there not being an oil leak in the system. The car received regular service. When we took it to Hyundai they did a test and confirmed that it was burning oil. This engine malfunction put my [XXX] daughter, the primary driver, at risk for engine failure while driving it. The engine light and knocking sound happened with no warning. Yes, the problem was confirmed by the Reed Hyundai of Kansas City. They told us that the car needs a new engine and that they bear no responsibility for the malfunction. The engine lights and sounds happened simultaneously. The vehicle was immediately stopped and towed to the dealership.

The car suddenly stopped accelerating. There were no signs that something was wrong prior. I was driving on the highway when I felt a loss of power, then my check engine light started blinking. The car entered “limp mode” and the engine started knocking. The code it was showing was for a knock sensor, I replaced that and it still would not accelerate. There is something wrong with the rod bearings and I was told by the dealership that this is a common problem with the type of engine they use in these vehicles.

NHTSA ODI 11626016

In August 2024, the engine of the vehicle suddenly started making a very loud knocking noise, with no previous warning lights. We did not feel it was safe to drive. We saw online that a recall was underway by Hyundai for 2017 Tucsons due to problems with the rod bearings, where metal spreads throughout the engine. There is the potential for the engine to catch fire, and a complete engine replacement is recommended. This was confirmed by the dealership where we bought the vehicle, Boucher Hyundai of Waukesha, which told us they are replacing the engines in many of these vehicles. However, our VIN was not included in the recall, although the problem is identical to what is described in the recall. We had the car towed to the dealership; after confirming the problem, the dealership filed a claim with Hyundai seeking to add our VIN to the recall. We included all of the maintenance records since we bought the vehicle in January 2021 with 64K miles. Hyundai rejected the claim, citing a gap in the maintenance records from 64,000-124,000 miles. The dealership questioned that, since they had submitted our maintenance records and there were no gaps. Hyundai again denied the claim, citing a gap in the maintenance records from 17,000-29,000 miles - before we owned the vehicle. We called Hyundai customer service seeking an explanation; they said that the decision is made by Hyundai Motor America, a different entity, which only the dealership can contact, not vehicle owners. The customer service rep's only suggestion was to file a claim with your agency. The vehicle is parked and undriveable; it is available for inspection.

Car is using an abnormally large amount of oil. I reported to Hyundai. They sent me to a Hyundai dealership for an Oil Consumption Test. They confirmed that I do not have an oil leak under the automobile. The dealer is telling me “it’s completely NORMAL TO BURN THROUGH 1 QUART OF OIL FOR EVERY 1,000 MILES”. That would leave my automobile with only two quarts of oil after driving 3,000 miles. The owner’s manual does not state any of this. Now I am paying a significant amount of money on Oil Consumption Tests of which they are telling me I might need several before they MIGHT fix the problem. This 2017 Hyundai Tucson is one of the models and years affected.
