2017 Hyundai Tucson: hesitation when accelerating

Filed Aug 24, 2026 · Engine · MA

I have a 2017 Hyundai Tucson with a 1.6 turbo engine, and I have been experiencing massive oil consumption. Oil is coming out of the tail pipe with occasional big puff of smoke out of the tailpipe. Skipping and hesitation during acceleration, rough cold start, I have previously had the check engine light on with a multiple misfire code. I changed the plugs and the coils, and it did not resolve the problems. I then took it to the mechanic, and he told me that the car has to go to Hyundai because these are known problems with my particular motor. I took it to Balise Hyundai in Hyannis Mass. and was told that they know about these motor issues but could not help me because the engine light was not on.' If the light comes on, then bring it back and we will check it out'.I was then told that any work performed would be my responsibility to pay for it out of my pocket. If it a known problem by Hyundai, then I think that a recall or something should be posted so customers are not stuck with a very big service bill. Any help to get my vehicle running the way it was designed to would be greatly appreciated. Apparently, there are no recalls or campaigns about these issues on my vehicle even though they are well known to Hyundai

#1. This vehicle uses a lot of oil !!! It burns through it like crazy I have to check the oil every other day. #2. When I come to a stop while driving and give it gas to take off IT WONT GO !!!!! It hesitates and when it does go it LUNGES FORWARD!! This is a huge manufacturer problem not a buyer problem. The engine is junk.! 3. I’ve called numerous places to get help. This car needs to be recalled. This is a huge safety violation. It doesn’t wanna go when you give it gas and when it does, it lunges forward that can cause a huge accident on the highways. This car was made in China. It is junk. I’ve called to get help with this issue and no one wants to help. Nobody returns my calls and I’ll Hyundai wants to do is it even more money out of me when this isn’t my fault the car is junk. For safety concerns I would like someone to call me at [XXX]. This car needs to be recalled and my daughter has one. It’s doing the same thing except hers is a lot worse. Hers is further advance where it’s actually stalling in the middle of the road while driving huge safety violation.

The vehicle has experienced life-threatening safety defects during operation; shaking, hesitation, and stalling in high-speed traffic. The vehicle unexpectedly stalled/lost power while driving, putting myself and others in direct risk of collision. The Hyundai dealership claimed it needed an Actuator Gasket replacement, Throttle Body replacement, and ECM/TCM update. The vehicle had NO warning lights until after it stalled, then warning lights illuminated briefly. The Hyundai dealership claimed repairs were "completed" 5/8/26; within 72 hours of "completion" the vehicle's symptoms reappeared. The Hyundai Executive Case Manager has made NO efforts to resolve this LIFE-THREATENING SAFETY issue. This has put myself and children in danger and is legally unsafe to drive.

While driving my vehicle, the engine RPM suddenly revved very high, and the vehicle hesitated to accelerate. A warning messaged appeared stating "Transmission too hot stop safely." I was driving up a hill when this happened. I pulled over and turned the vehicle off for about two minutes. When I restarted the vehicle, the warning message disappeared even though the vehicle would not realistically have cooled down that quickly. The issue concerns me because it could create a dangerous situation in traffic if the vehicle loses power or hesitates to accelerate when pulling into traffic or climbing a hill. The problem has occurred without warning and does not leave and persistent warning lights afterwards. I am very scared to drive this car, especially when I have my child with me. If I need to move out of the way and someone is driving that is not paying attention, there will be an accident because of the hesitation and the non-movement when I accelerate. I am reporting this issue in case it is related to a defect with the transmission system in this vehicle.

the federal safety agency Complaint – 2017 Hyundai Tucson Oil Consumption, Engine Defect, and Branded Title I am filing this complaint regarding my 2017 Hyundai Tucson, which suffers from abnormal oil consumption and engine problems. In addition, Hyundai Motor Company internally “branded” the title without disclosure, which voided my eligibility for warranty coverage. These issues create both serious safety risks and consumer protection concerns. 1.Oil Consumption and Engine Issues •This Tucson has had oil consumption problems since the first owner, which I only discovered a year after purchasing the vehicle. •The vehicle burns oil excessively between service intervals, often requiring top-offs after just a few hundred miles. •Critically, the low oil pressure warning light provides no early warning. It only activates once oil levels are already dangerously low, leaving no safe margin to protect the engine. •On multiple occasions, I was unaware the engine oil had dropped to unsafe levels until the vehicle was already at risk of engine damage. •The engine makes knocking/tapping noises, hesitates under acceleration, and has rough idling when oil levels drop — all signs of internal engine damage that could lead to sudden failure while driving. 2.Hyundai’s Branded Title Practice •Roughly one year after purchasing from CarMax, I learned that Hyundai had internally branded the title in their own system due to oil consumption reported by the first owner. •This branding was never disclosed to me or to CarMax, and the official state-issued title and Carfax report both showed “clean.” •Hyundai uses this internal branding to void the extended engine warranty that should have applied to my vehicle. •Despite repeated requests, Hyundai has refused to provide documentation of when or why this branding occurred. 3.Warranty and Safety Concerns •Hyundai has issued Technical Service Bulletins (TSBs) and extended warranties for engine failures caused by piston rings and bearings

My 2017 Hyundai Tucson Limited 1.6L Turbo (with 7-speed EcoShift DCT) has ongoing transmission problems. The vehicle hesitates, jolts, and sometimes fails to accelerate from a stop, which creates a serious safety risk when entering traffic or crossing intersections. The problem has been reproduced and confirmed by the Hyundai dealership in Fairfield, CT. They diagnosed the transmission and recommended a complete replacement at a cost of over $7,000. This issue matches the defect described in the federal safety agency Recall 16V628000 and Hyundai Service Campaign T1B, which involved the same 7-speed EcoShift DCT in 2016–2017 Tucson models. However, my VIN was not included even though I am experiencing the exact same safety defect. No warning lamps appeared before the hesitation/judder began. The safety risk is significant because the vehicle can fail to accelerate as expected in traffic, increasing the chance of a crash.

Hyundai Tucson 2017 – Known Transmission Defect Ignored I own a 2017 Hyundai Tucson with the dual-clutch transmission. For months I experienced serious hesitation and sputtering when accelerating from a stop or low speed—a clear safety risk when trying to merge into traffic or cross intersections. On July 23, 2025, I dropped my vehicle at Huffines Hyundai in Plano. It sat there for nearly a month until August 21, when they finally admitted they could reproduce the issue. The problem matched exactly what Hyundai itself identified in its own service bulletins regarding this model’s transmission. Despite acknowledging it’s a known defect, Hyundai: Refused to cover the repair, Would not even reimburse my $200 third-party warranty deductible, Has failed to issue a recall, leaving countless owners with the same unsafe problem. This is deplorable customer care. Hyundai and its dealerships know this defect exists, can reproduce it, and yet leave customers to pay out of pocket for a manufacturer-caused safety hazard. Buyers should beware—Hyundai is not standing behind its vehicles.

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.

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

My car hesitates when leaving a stop sign or light. It is random and I have no power to continue. If I put car in park than go sometimes it works, sometimes push down on gas more or sometimes I have to turn car off than back on. 2 near miss accidents
