Hyundai Tucson · Years to avoid & years to hunt · 20162023

The 2016–2018 are loud with the engine-bearing story; 2020–2021 are the calmest; the 2022 redesign re-spikes.

Eight years across two Tucsons. The 2016–2021 third generation is defined by the connecting-rod-bearing engine problem — knock, oil consumption, seizure — which Hyundai chased with a knock-sensor campaign and a warranty it extended in stages up to a lifetime engine coverage. The 2022 redesign brought hybrid and plug-in versions and a fresh launch-year cluster: fuel-injector misfires, low-speed drivetrain scares, and fire recalls. Here's the story, year by year.

Evidence: 4,312 federal complaints analyzed · 17 recall campaigns · 8 full-year reports · mechanic & forum testimony throughout

The short version
Best years
2020 · 2021

Late third-gen years; lowest complaint volume, engine story largely settled, only the ABS-fire recall to close

Avoid
2016 · 2017

The loudest years — engine-bearing knock, oil consumption, and seizures; buy only with the bearing coverage and recalls documented

The dividing line is 2022. Everything before is the third-gen car whose question is the connecting-rod-bearing engine — expensive, but covered in stages up to a lifetime warranty if the paperwork is there. Everything from 2022 is the redesigned car whose question is the launch-year injector and drivetrain cluster. Both come down to checking recalls and one drivetrain test before you buy.
The shape of the story: complaints run highest on the third-gen launch years (2016: 1,611, 2017: 1,073), then fall hard (2018: 383, 2019: 369, 2020: 170, 2021: 72). The 2022 redesign re-spikes to 472 across gas, hybrid, and plug-in, then settles to 162 for 2023. The loud cluster shifts from engine bearings to fuel injectors and drivetrain hesitation.

The short list

Where the money goes wrong — and where it doesn’t.

✕ Years to avoid

2016

The loudest Tucson year. 1,611 federal complaints, overwhelmingly engine — knock, oil consumption, and connecting-rod-bearing seizure on the GDI engines. Hyundai's KSDS knock-sensor campaign and a staged engine-warranty extension (up to a Limited Lifetime Warranty for the bearing repair) are the saving grace. Buy only one with that work and the ABS-fire recall documented.

2017

The year with its own engine-replacement recall. 1,073 complaints, same engine story, plus recall 21V727 — Hyundai specifically inspects the engine for bearing wear and replaces it free if damaged. Confirm 21V727 shows completed by VIN; an unverified one is a gamble on the most expensive part of the car.

2022

The redesign's busy launch year. 472 complaints across gas (360), hybrid (105), and plug-in (7). The 2.5L direct-injection engine draws fuel-injector misfires; all three powertrains draw low-speed hesitation and surges, and the plug-in a stuck-in-neutral scare. Three recalls, including a tow-hitch fire risk. First-year caution applies.

✓ Years to hunt for

2021

The calmest third-gen year. 72 complaints, the lowest in the set, and the engine-bearing flood is behind the model by this point. The only open safety recall is the ABS-fire campaign (20V543). Close that out and it's the most straightforward third-gen Tucson to buy.

2020

Quiet and covered. 170 complaints, residual engine noise, and the same ABS-fire recall to verify. The KSDS coverage and staged bearing warranty still apply. With the recall closed, one of the safer picks in the generation.

Same year. Different engine.

One badge, several engines — the year’s verdict assumes the riskiest one. Yours might be the calm one.

Which engine is in the one you found?

Where the years split by engine — the 2022 line divides two different Tucsons
2.4L GDI / 2.0L Theta II (gen 3)
Squawking

The connecting-rod-bearing engines. The third-generation gas engines (2016–2021) — a 2.4L GDI (Gasoline Direct Injection) and a 2.0L. These are the engines behind the Tucson's defining problem: oil consumption that creeps up, then knock, then connecting-rod-bearing wear that can seize the engine or start a fire. Hyundai's response is the KSDS (Knock Sensor Detection System) campaign (Service Campaign 966), which listens for the early bearing signature, plus a bearing-engine warranty extended in stages — 10 years/120,000 miles, then 15 years/150,000 miles, then a Limited Lifetime Warranty valid for subsequent owners. 2017 also carries its own engine-inspection recall, 21V727. Confirm the tier that applies to a VIN with Hyundai.

2016–2021
1.6L turbo + 7-speed dual-clutch (gen 3)
Chirping

The turbo trim's transmission quirk. The third-gen 1.6L turbo trims pair with a 7-speed EcoShift dual-clutch transmission (DCT) that can shudder and hesitate at low speed. Recall 16V628 addressed a condition where heat and repeated pedal input could leave the car unable to move (TCM software), and Hyundai ran further control-module reflashes for shift quality. On a test drive, creep in traffic and treat a persistent low-speed lurch that software can't cure as a walk-away.

2016–2021
2.5L GDI Theta III (gen 4, gas)
Squawking

The redesign's gas engine — and its injectors. The fourth-generation gas engine (2022–2023), a 2.5L direct-injection four that mechanics and owners call adequate at best (187 hp). Its recurring problem is a fuel injector leaking internally from a broken filter, causing a cylinder misfire — check-engine light, shaking, power reduction, often near cylinder 3. Hyundai's bulletin replaces all four injectors. On 2023 it also falls under recall 23V526, the Idle Stop & Go oil-pump-controller fire risk. Covered under warranty; expensive out of it.

2022–2023
1.6L turbo hybrid / plug-in (gen 4)
Chirping

The electrified Tucsons. The fourth-gen hybrid and plug-in-hybrid use a 1.6L turbo engine paired with an electric motor. Their defining complaint is a delayed response accelerating from a stop as the system hands off from electric to gas power, producing near-misses pulling into traffic; the plug-in also drew a low-mileage stuck-in-neutral pattern, and the hybrid an oil-pan leak. Most are warranty repairs on these years — test low-speed acceleration deliberately and confirm any oil leak was resolved.

2022–2023

The VIN encodes which engine and powertrain you're looking at — paste it and we'll tell you which row applies, plus its open recalls. The gen-3 rows share the ABS-fire recall (20V543) across the whole 2016–2021 catalog; the gen-4 rows share the tow-hitch fire recall (25V893).
