Hyundai Tucson 2016–2021

3rd generation (TL) · TL · 5,013 complaints, 2,053 with mileage

Owners filed 5,013 complaints with NHTSA about the 2016–2021 Hyundai Tucson, and 2,053 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

38% of failures fall within the first 12,000 miles. Failures clustered that early usually indicate a design or manufacturing problem rather than wear.

The most-reported areas are the engine (30.8% of complaints, typically around 55,800 miles), the transmission and driveline (19.2% of complaints, typically around 7,800 miles), problems owners could not categorise (10.0% of complaints, typically around 26,742 miles).

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 25,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The engine accounts for 30.8% of complaints (1,545 reports, 458 of them with a mileage figure), and it fails late — a median of 55,800 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 15,500 and 86,790 miles.

A single system taking 30.8% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.

The transmission and driveline accounts for 19.2% of complaints (964 reports, 601 of them with a mileage figure), and it fails early — a median of 7,800 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 2,200 and 22,000 miles.

Problems owners could not categorise accounts for 10.0% of complaints (502 reports, 152 of them with a mileage figure), with a median of 26,742 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 5,600 and 60,000 miles.

The electrical system accounts for 8.0% of complaints (400 reports, 157 of them with a mileage figure), and it fails late — a median of 40,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 8,500 and 70,000 miles.

Body structure accounts for 5.8% of complaints (289 reports, 136 of them with a mileage figure), and it fails late — a median of 58,450 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 40,000 and 70,000 miles.

Throttle and speed control accounts for 4.7% of complaints (235 reports, 138 of them with a mileage figure), and it fails early — a median of 9,362 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 2,200 and 29,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2016 model year drew the most — 2,166 complaints — while 2021 drew the fewest at 106. The median year sits at 527.

That makes 2016 an outlier: roughly 4.1 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.

Recalls and what they cover

NHTSA records 6 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 5,013 complaints filed against this generation, 96 reported a crash; 117 reported a fire; 77 reported an injury; 2 reported a fatality. Crash-involved reports represent 1.9% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, an early-failure pattern is comparatively good news on a used example: 38% of the reported failures occur in the first 12,000 miles, which on a car of this age means they have already happened or they were never going to. Service history matters more than mileage here.

On inspection, the engine and the transmission and driveline are where this generation's reports concentrate, so those are the areas worth a specific look. The transmission and driveline in particular shows a median failure mileage of 7,800, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Documented problems

Transmission (7-speed DCT) 2016-2018

Clutch application logic causes delayed engagement, hesitation and jerking at low speed, and repeated accelerator pedal cycling in high ambient temperatures can leave the vehicle unable to accelerate at all; owners also report loss of power and stalling. NHTSA recall 16V-628 covered 2016 Tucsons with the 7-speed DCT built 20 May 2015 to 31 May 2016; a class action settled for $41.2 million with a warranty extension and repair reimbursement, and MY2017 cars required a TCM software update.

Engine (2.4L Theta II GDI) 2016-2019

Connecting-rod bearing wear and seizure from oil-passage debris — the same Theta II mechanism as the LM, covered by the engine settlement and KSDS software campaign.

Brakes / ABS (HECU) 2019-2021

Electrical short in the ABS hydraulic electronic control unit can ignite even with the vehicle parked and off; Hyundai issued recalls with a park-outside advisory covering 2019-2021 Tucsons among other models.
