About the 2022 718 Boxster GTS 4.0

2022GT4 RS arrives with the 992 GT3 engine, 9,000 rpm and PDK only. PDK becomes an option on the GT4 and Spyder.

718 Boxster GTS 4.0Naturally aspirated 4.0 L flat-six to 7,800 rpm. Porsche conceding the argument, and the version to buy if you can.

Known issues

5 Specific to the 718 Boxster GTS 4.0

PDK mechatronic faults

Major $1,400–$9,000
Affects

PDK-equipped cars.

What happens

Sensor and solenoid faults in the mechatronic unit produce harsh engagement, refused gears or a limp-home restriction. A well-proven unit by this point, but still the most expensive drivetrain component to put right.

Symptoms
  • Harsh or hesitant low-speed engagement
  • Transmission warning message
  • Refusal to select a gear
  • Limp-home restriction
What to do

Keep the fluid and filter service current. Many cars remain inside warranty coverage — verify before assuming otherwise.

Coolant pump failure

Major $900–$2,000
Affects

All 982, more commonly at higher mileage.

What happens

The coolant pump fails and can shed impeller material into the cooling system. Straightforward if caught early, considerably worse if not.

Symptoms
  • Temperature climbing in traffic
  • Coolant weeping at the pump
  • Coolant loss with no external leak
  • Overheat warning under load
What to do

Replace with the thermostat while the system is open.

Parts for this job

Infotainment and connectivity faults

Minor $0–$600
Affects

All 982, most commonly the earliest cars.

What happens

PCM screen freezes, reboots and CarPlay connectivity complaints are common and mostly software rather than hardware.

Symptoms
  • Screen freezing or restarting
  • CarPlay disconnecting
  • Bluetooth pairing failures
  • Spurious assist warnings
What to do

Most resolve with a dealer software update. Confirm a car is on current software before chasing a hardware fault.

Convertible top faults

Minor $300–$1,600
Affects

Boxster.

What happens

The automatic top depends on sensors, microswitches and hydraulics that can fault with age.

Symptoms
  • Top stopping partway
  • Warning message when operating the roof
  • Roof not latching cleanly
What to do

Usually a sensor rather than the mechanism. Cycle it fully several times at inspection.

Short failure record on the 4.0 six

Minor
Affects

All 4.0 L flat-six cars: GTS 4.0 from 2021, GT4 and Spyder from 2020, GT4 RS and Spyder RS.

What happens

The naturally aspirated 4.0 — in GTS, GT4, Spyder and RS forms — is closely related to the 992 GT3 engine and has a good early reputation, but it has not been in the world long enough for a statistically meaningful failure picture.

Symptoms
  • Treat confident long-term reliability claims about this engine, positive or negative, with suspicion
What to do

Buy on service history, keep it in warranty where you can, and check for open recalls by VIN before purchase.

Does not affect this car

Emissions sensor and particulate filter faults — documented elsewhere in the 982 range but not applicable to the 718 Boxster GTS 4.0. See the generation overview for the full picture.

Buying guide

7
  1. 01

    Drive the flat-four before you dismiss it

    The internet decided this engine was a disgrace before most people had driven one. It is quicker and more flexible than the six it replaced, and the chassis underneath is the best Porsche makes. It also sounds ordinary, and only you can price that.

  2. 02

    The GTS 4.0 is the one to stretch for

    Naturally aspirated flat-six to 7,800 rpm, available with a manual, in the same superb chassis. It is the version that resolves every complaint about the generation, and the used market has priced that in.

  3. 03

    Check warranty and recall status by VIN

    Many 982s are young enough that factory or approved-used coverage is still live, and that is worth more than any inspection you can buy.

  4. 04

    Insist on PDK fluid history

    Records separate a maintained gearbox from a gamble on the most expensive part of the drivetrain.

  5. 05

    Options move the price more than mileage

    PASM, Sport Chrono, Sport Exhaust, the limited-slip differential and the sports seats all hold value. A sparsely optioned car is a slow sale later regardless of how few miles it has.

  6. 06

    Manual is the configuration people hunt

    PDK is quicker and the manual is what the market wants, particularly on a GTS 4.0. That gap is not closing.

  7. 07

    Cycle the top fully on a Boxster

    Reliable by the standards of the older cars, but still cheaper to find a fault before buying than after.

Parts and gear

13 Chosen for this car, not for the commission

What a 718 Boxster GTS 4.0 actually costs to keep, grouped by why you would buy it. Prices are typical US parts-only figures — labour is separate, and the DIY note says whether that matters. Where a link earns us a commission it costs you nothing and never changes what appears here.

Parts that fix a known problem on this car

1 Each one maps to an issue above
  • Cooling $350–$850

    Coolant pump and thermostat

    The failure above and its fix. Replace the thermostat at the same time — the system is open and the labour overlaps.

Worth doing before it fails

3 Cheaper than the repair it avoids
  • Exterior $700–$2,400

    Paint protection film for the nose

    A low, wide front end on a car that rewards being driven a long way. Film the bumper, bonnet, mirrors and rocker edges before the first road trip.

    Shop this → Shop job
  • Cooling $110–$260

    Radiator grille screens

    Low front radiators and open ducting collect road debris exactly as every water-cooled Porsche before them.

    Shop this → DIY
  • Chassis $280–$650

    Engine and transmission mount set

    Worth doing on a high-mileage car that feels less crisp than it should. Cheap relative to how much sharpness it restores.

Consumables you will rebuy

5 Ordinary running costs
  • Fluids $280–$580

    PDK fluid and filter kit

    The service that protects the mechatronic unit, and the one most likely to have been skipped.

    Shop this → Shop job
  • Fluids $85–$170

    Porsche-approved engine oil

    Approved specification only, and non-negotiable while the car is under warranty. Keep every receipt.

    Shop this → DIY
  • Fluids $20–$55

    Oil filter and hardware

    Bought with every change. Use the specified part on a warrantied car and keep the paperwork.

    Shop this → DIY
  • Fluids $20–$75

    Brake fluid

    Two years, annually with track use. The least glamorous and most important consumable on a car this capable.

    Shop this → DIY
  • Service $35–$95

    Cabin and engine air filters

    Routine, cheap, and heavily marked up when a dealer does them.

Tools worth owning

4 Bought once, used for years
  • Diagnostics $250–$1,000

    Porsche-specific diagnostic interface

    Separates a software glitch from a real fault before you book dealer time — which on a 982 is most of the diagnostic battle.

    Shop this → DIY
  • Wheels $80–$280

    Torque wrench and correct sockets

    Expensive wheels and no guarantee anyone else torqued them properly. Verify after any tyre work.

    Shop this → DIY
  • Lifting $180–$480

    Low-profile jack and jack pads

    The 982 sits low and its jack points need proper pucks to avoid crushing the sill.

    Shop this → DIY
  • Storage $60–$150

    Battery tender

    A low battery on a car this electronically dependent produces faults across unrelated systems.
