    On the 2021-2024 Porsche 911, nHTSA recall 24V-809 covers 2021-2024 Porsche 911s (alongside 2024 718 Cayman GT4 RS and Spyder RS and the 2025 Panamera) in which "the center lock wheel bolt may fracture and cause the wheel to detach." A batch of center-lock nuts was manufactured out of specification. This is strictly a center-lock-wheel fault, so within the 992 range it applies only to the variants that use a single central fastener per corner - GT3, GT3 RS, S/T, Turbo S and other center-lock-optioned cars - and not to the five-bolt Carrera and Carrera S. Porsche told owners not to drive affected cars until the fastening system had been checked. Roughly 1,851 to 2,251 units were involved in the US, built September through December 2023, so exposure is concentrated in late-2023-build cars even though the recall population is stated across 2021-2024.

    Common Symptoms

    • Clicking or knocking from a wheel that changes with steering load
    • Visible movement or play at the center-lock nut
    • Wheel detachment without prior warning

    How to Fix

    Stop driving the car and run the VIN against NHTSA 24V-809 (Porsche campaign ARC4). Dealers inspect the complete center-lock wheel fastening system and replace any out-of-specification parts free of charge. Because a center-lock fastener carries the entire wheel load, do not simply re-torque it - the failure mode is fracture of the bolt material, not loosening, so a torque check will not reveal it.

    On the 2020-2026 Porsche 911, porsche Technical Information 40/21 ENU 4381 covers 911 Carrera (992) cars from model year 2020 fitted with the front-axle lift function (M-no. 2UH). The white warning message "Lift system fault - Service necessary" appears in the instrument cluster and the entry "C1365F8 - Measuring height fault (000302)" can be stored in the front-axle lift system control unit. Porsche states plainly that "this fault type can occur if the vehicle was parked with the body front end raised," and warns owners to "always park the vehicle at the lowered position, as the upper holding position cannot be guaranteed over a long period of time with the engine stopped." A large share of these faults are therefore induced by how the car is parked rather than by a failed component. Owners on Rennlist separately report hydraulic failures where the system lifts but will not come back down, and a case of a lift strut boot blowing out at around 7,500 miles and spraying hydraulic fluid into the wheel well - so a genuine hydraulic leak still has to be ruled out before assuming a parking-induced code.

    Common Symptoms

    • White "Lift system fault - Service necessary" message in the instrument cluster
    • Front axle lift raises but will not lower
    • Lift button indicator stays red or does not respond
    • Hydraulic fluid in the front wheel wells or on the lift strut boot

    How to Fix

    Lower the front axle before switching off the engine, every time - this is Porsche's own instruction and the single most effective preventive measure. If the warning message and the height-measurement entry are both displayed, the workshop must perform the front ride-height measurement and check per TI 40/21 before condemning parts. Inspect the lift strut boots and fittings for hydraulic fluid in the wheel wells: leaky fittings are a separate, real failure that also triggers this message and will not be cured by clearing the code.

    Typical repair cost:$200 - $3,000

    On the 2020-2024 Porsche 911, porsche's Part 573 report for recall 24V-155 states that on affected 992-generation 911s "the front and rear windows were not manufactured in accordance with the specifications and therefore not bonded sufficiently to the body." The root cause was a supplier cleaning-process error: residues of a potassium salt bath left in the primer area prevented adhesion to the glass. Porsche was informed of optically impaired windows in the field in November 2023. 8,101 US vehicles built 08 JUL 2019 - 30 OCT 2023 are involved, with an estimated 10 percent defect rate. Affected glass part numbers are 992845099CM and 992845099DB (windshield) and 992845047R and 992845047S (rear window), supplied by Pilkington San Salvo. Owner-visible warning signs listed by Porsche are wind noise, water ingress, or both - so a 992 with an unexplained wind whistle or damp footwell should be checked against this campaign rather than chased as a seal or drain problem.

    Common Symptoms

    • Wind noise from the top or edges of the windshield at speed
    • Water ingress into the cabin or luggage area after rain or washing
    • Cloudy or optically distorted areas near the glass edge
    • Glass edge that appears to lift or move slightly under pressure

    How to Fix

    Check the VIN against NHTSA recall 24V-155 (Porsche campaign ARA3). Dealers inspect the bonding of the windshield and rear window and replace either or both as necessary at no cost. Do not have the glass replaced by an independent shop before the recall inspection - the campaign covers both the diagnosis and the OEM-spec re-bond, and an aftermarket replacement forfeits it.

    On the 2022-2023 Porsche 911, nHTSA recall 22V-897 covers 2022-2023 Porsche 911s in which the dashboard console may break during a crash where the passenger airbag deploys. Because the airbag pushes against the dashboard structure as it inflates, a console that fractures lets the bag deploy out of position, so "improper air bag deployment increases the risk of injury in a crash." This is a structural interior-trim defect specific to the 992's dashboard assembly, not an airbag module or sensor fault, and it will not set a code or illuminate the airbag warning lamp - the defect is only revealed in a deployment event.

    Common Symptoms

    • No warning symptoms - defect only manifests during passenger airbag deployment

    How to Fix

    Check the VIN against NHTSA 22V-897 (Porsche campaign ANB7). The remedy is replacement of the complete dashboard free of charge. There is no owner-detectable symptom and no diagnostic test, so VIN lookup is the only way to establish exposure.

    On the 2022-2023 Porsche 911, porsche Technical Information 65/23 ENU 9152 covers 911 (992) model years 2022 through 2023 running central computer (PCM) software version 37xx. Porsche describes the condition as "the PCM cannot be switched on, fails intermittently during vehicle operation or starts up again independently," and lists the error patterns explicitly: the PCM screen remains black; there is no sound output and the hands-free device is faulty; the navigation display fails; and the PCM can only be started again after some time or starts up again on its own. On cars with the BOSE Surround Sound System (M-no. 9VL) or Burmester 3D High-End Surround Sound System (M-no. 9VJ), the sound settings under Media are additionally lost after bus rest - "Heights and depths" and "Balance and fader" become unticked and the bars reset to zero - and Real Time Traffic stops showing traffic jams in the route monitor text. A separate MY2022 workshop campaign, WNT1 (TI 236/22 ENU), re-programs the Connect control unit and central computer with optimized software. Owners report the same blank-screen and reboot behaviour on Rennlist, where the usual workaround is a hard PCM reboot rather than a permanent fix.

    This issue also affects: Audi Q7, Porsche Macan, SEAT Leon

    Common Symptoms

    • PCM screen goes black and will not switch on
    • PCM reboots itself or restarts on its own after a delay
    • No audio output and non-functional hands-free calling
    • Navigation display fails
    • BOSE or Burmester equalizer and balance/fader settings reset to zero after the car sleeps
    • Real Time Traffic no longer shows congestion in the route monitor

    How to Fix

    Have the central computer (PCM) re-coded with the latest PIWIS Tester software; the minimum requirement for coding under TI 65/23 is PIWIS Tester software version 42.500.020, and the update is loaded from a 32 GB Type A+C USB stick (part V04014999WW000). MY2022 cars should also be checked in PCSS for open workshop campaign WNT1, which re-programs both the Connect control unit and the PCM (minimum PIWIS version 41.800.010). As a stopgap the PCM can be rebooted by pressing and holding the center console volume control for about ten seconds, but settings must then be reconfigured and the underlying software fault returns until the update is applied.

    On the 2020-2026 Porsche 911, porsche Technical Information 31/20 ENU 2706, "Diagnosis and Handling of 12-Volt Lithium-Ion Battery (On-Board Battery)," covers the 911 Carrera (992) alongside the Cayenne and Taycan and applies to cars fitted with the lightweight lithium battery (I-no. J2A). Porsche wrote the bulletin because "on vehicles in which a lithium-ion vehicle electrical system battery is installed, the battery is sometimes replaced even though it is not defective." When the battery's component protection function activates, "the 12-volt on-board power supply battery is disconnected from the vehicle via an integrated separating element and the vehicle is subsequently de-energized" - which the owner experiences as a completely dead car that cannot be unlocked or made ready to drive, and which workshops frequently interpret as a failed battery. The protection trip is temporary and reversible using the correct reset measures, so an owner of a lightweight-battery 992 should treat an unexplained total electrical shutdown as a protection event until diagnosis proves otherwise.

    Common Symptoms

    • Car completely de-energized and cannot be unlocked with the key or remote
    • Vehicle cannot be made ready for driving despite a recently good battery
    • No response at all from the electrical system, not even a relay click
    • Repeat battery replacements that do not solve the problem

    How to Fix

    Before any battery is replaced, the workshop must carry out the battery diagnostics described in the Battery Diagnostics section of TI 31/20 to establish whether the battery is genuinely defective or whether only a temporary, reversible component protection function has activated. Never connect an ordinary trickle charger or jump pack to a J2A lithium car: lithium starter batteries may only be charged by a charger with a current- and voltage-controlled charge map (Porsche cites the Charge-o-mat Pro and the VAS 5908 90A). Charging a lithium battery on the wrong profile is itself a common way to trip protection or damage the pack.

    On the 2020-2026 Porsche 911 3.0L twin-turbo flat-six (9A2 Evo), porsche Technical Information 88/20 ENU 3734, "Complaint - Oil Leaks on Double Clutch Transmission (Porsche Doppelkupplung PDK)," covers the 911 Carrera (992) from model year 2020 with the 8-speed automatic transmission (I-no. G1F) and the 8-speed all-wheel-drive transmission (I-no. G1G). Porsche publishes a full sequenced diagnostic covering leak locations on the right, left, upper, lower, rear and front faces of the transmission, and specifies that oil leaks must be clearly identifiable and reproducible with engine oil and coolant at operating temperature after a test drive, and that if oil is leaking from the final drive or hydraulic chamber breather both hoses must be disconnected to find the exact location. Leaks from the breather are a distinct condition from housing-seal leaks and are frequently misread as a case leak. Separately, 992 owners on Rennlist report PDK complaints including hesitation and delayed engagement pulling away from a stop, jerking in first and second gear, and intermittent transmission error messages that clear on restart; Porsche replaces rather than dealer-rebuilds a failed PDK, which makes an out-of-warranty failure very expensive.

    Common Symptoms

    • Oil drips or wet film on the transmission housing
    • Oil residue at the final drive or hydraulic chamber breather
    • Transmission fault messages in the instrument cluster
    • Hesitation or delayed engagement when pulling away from a stop
    • Jerking or clunking in first and second gear

    How to Fix

    Have the leak located using the sequenced procedure in TI 88/20 rather than a single visual inspection - the bulletin exists because leaks on this unit are commonly attributed to the wrong seal. The car must be test-driven to operating temperature and the leak must be reproducible before any seal is replaced, and the final drive and hydraulic chamber breather hoses must be disconnected to separate a breather discharge from a genuine seal leak. Address PDK oil loss while under warranty: Porsche does not rebuild the PDK at dealer level, so a unit run low on fluid becomes a full replacement.
