Kestrel Take

The first year of the redesigned G80 — the long-hood car with the two-line lights, a 2.5-liter turbo four or a 3.5-liter twin-turbo V6, and an eight-speed automatic. NHTSA holds only nine complaints for it, none with a crash or fire, so the owner record tells you almost nothing; the recalls do the talking. Four of them, and three are fuel: a high-pressure fuel tube on the 2.5T that can leak (2021), a fuel pump that can quit and leave the car without drive (2023), and a fuel-rail pipe connection that can leak, added in 2026 across every year of this generation. The fourth is a seat-belt pretensioner that can throw metal fragments when it fires. All are free fixes and all are the kind that matter. The nine complaints add a brake pedal that taps at a standstill, a dashboard that went dark, and 20-inch tires with sidewall failures. A first-year car with a lot of new hardware and a thin file; buy it with every recall closed on the VIN and a dealer confirming what warranty remains, and know that nine complaints is not a reliability rating.

What we checked

Checked against public records, 2026-09-25

NHTSA holds 9 owner complaints for the 2021 Genesis G80, and 4 recall campaigns.

That is too small a record to read a pattern from, so we are not going to pretend otherwise — with numbers this low one owner moves the percentage by a lot. What has been filed is grouped under the brakes (3), tyres (3), electrics and electronics (2). Treat those as things to look at, not as the vehicle's known weaknesses. A thin file usually means few of these were sold or few owners filed. It is not evidence the vehicle is trouble-free, and the issues below are our own research rather than a reading of this record.

4 recall campaigns cover this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.

Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.

Known Issues for the 2021 Genesis G80

Ranked by wallet impact. These are documented, recurring problems — not freak accidents. How we decide that.

Fuel can leak at the high-pressure tube on the 2.5T, and at the fuel-rail pipe connection on any engine (two recalls)High — wallet impact

Recall 21V208 covers 2021 G80s with the 2.5-liter turbo: the tube between the high-pressure pump and the fuel rail may not seal, and fuel dripping near a hot engine is a fire risk. Dealers replace the tube free. Recall 26V229 came five years later and applies to 2021–2025 G80s: fuel can leak at the connection between the fuel pipe and the rail, and dealers inspect, tighten or replace the pipe. Letters for the second one only began going out in July 2026, so a car sold today may not have had it done. Check both on the VIN, then open the hood after a warm drive and smell for raw fuel around the top of the engine; any fuel smell is a walk until it is fixed.

Repair cost: $0 with the recall — verify it was performed

Fuel pump can fail and cut power while driving (recall)High — wallet impact

Recall 23V630 covers 2021–2022 G80s: the fuel pump may fail outright, and a car that loses fuel pressure at speed loses drive with traffic behind it. The fix is a new pump, free, with letters mailed in November 2023. This is a part swap that shows on an invoice, so ask for the paperwork. On the test drive, listen for a whine from the rear seat area at idle and watch for any hesitation or stumble under hard acceleration from a stop, which is how a pump on its way out first shows itself.

Front seat-belt pretensioners can explode and throw metal fragments in a crash (recall)Medium

Recall 23V094 covers 2021–2023 G80s along with the GV80, GV70 and GV60: in a crash the front driver or passenger pretensioner can rupture when it fires, sending fragments into the cabin. The remedy is a cap fitted over the pretensioner, free, with letters mailed April 2023. There is nothing to inspect at the car; it is a VIN check and a dealer stamp. If the lookup shows it open, have it done before anyone rides in the front seats.

Brake pedal that taps and pulses at a standstill, and a dashboard that went dark with every warning litMedium

Two owners describe pressing the brake in Drive while stopped and feeling a tapping through the pedal, one from 26,000 miles on; on a car with this much brake-by-wire and auto-hold logic that is usually the ABS or brake-booster pump cycling, and it belongs at a dealer under warranty rather than in a shrug. A third owner had the instrument cluster fail completely — no speedometer, tachometer, turn signals or odometer, with the airbag and power-steering warnings on at once. Sit at a stop in Drive with your foot on the brake for a full minute and feel the pedal; then cycle the ignition a few times and make sure the cluster comes up cleanly every time.

Repair cost (estimate): $0 under the factory warranty; $500–$2,000 for a brake-pressure unit or instrument cluster outside it

20-inch tires with sidewall failures before 25,000 milesMedium

Two owners of cars on the 245/40R20 front and 275/35R20 rear fitment report sidewall blowouts — one lost three tires inside 25,000 miles, another had a rear go flat and then the front burst a mile later on the way to get it fixed. A third complaint in this cluster is a GV80 misfiled here. Low-profile tires on a 4,500-pound car in pothole country will do this, and the 20s are also expensive to replace. Look at the date codes and brand on all four, run your fingers around each sidewall for bulges, and budget for a set if they are original; a car on 19s is cheaper to keep shod.

Repair cost (estimate): $1,000–$1,600 for a set of four 20-inch tires

Power windows that stop responding from every switch, even after a warranty repairLow

One owner reports all four windows refusing to move from any switch, intermittently, and coming back from a warranty repair only to fail again the next day. On a car this new that points at a body-control or door module rather than a motor, and it should be a warranty visit — but a dealer that has already been once and missed it is a dealer you want to know about. Work every window from the driver's door and from its own switch, up and down, twice, before you leave the lot.

Repair cost (estimate): $0 under the factory warranty; $200–$700 for a door or body control module outside it
