On the 2025 Porsche 911, nHTSA recall 25V-079 covers 2025 Porsche 911s among other Porsche models. Porsche states that "a software error in the front-end electronics control module may result in the low beam headlights creating a glare for oncoming traffic," and that "excessive glare can decrease the visibility to oncoming drivers, increasing the risk of a crash." This is a lighting-control software defect rather than a mechanical aim or leveling failure, so a manual headlight aim adjustment does not correct it - an affected car will pass a visual aim check while still dazzling oncoming drivers.

Common Symptoms

  • Oncoming drivers flashing their headlights at you while you are on low beam
  • Low beams appear brighter or aimed higher than normal
  • Headlight beam behaviour differs between drives with no setting change

How to Fix

Check the VIN against NHTSA recall 25V-079. The remedy is a free software update to the front-end electronics control module at a Porsche dealer. Do not attempt to compensate by re-aiming the headlights: the beam pattern is being produced incorrectly by the control module, and re-aiming only compromises the driver's own low-beam throw.

Typical repair cost:$0 - $0

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 2025-2026 Porsche 911, porsche Technical Information 07/25 ENU 4883 applies to the 911 Carrera GTS (992), 911 Carrera 4 GTS (992), 911 Turbo (992) and 911 Turbo S (992) from model year 2025 equipped with rear axle steering (M-no. 0N5). The customer complaint is that "the yellow warning message 'Rear axle steering failed' in the instrument cluster lights up in conjunction with dynamic cornering." The rear axle steering control unit stores C1445F2 (malfunction of right servo motor, 000015) and C11D1F5 (travel blocked, 000028). Despite naming the right servo motor and a blocked-travel condition, Porsche's remedy is a control unit re-programming, which indicates the codes are a software artifact rather than a mechanically seized actuator. Rear axle steering is optional on the GTS cars and standard on Turbo models, so this is fitment-gated - a 992 without M-no. 0N5 cannot exhibit it.

Common Symptoms

  • Yellow "Rear axle steering failed" message during hard or dynamic cornering
  • Rear axle steering disabled, with a noticeably larger low-speed turning circle
  • Warning appears intermittently and may clear on restart

How to Fix

Re-program the rear axle steering control unit using the PIWIS Tester. The minimum programming requirement is PIWIS Tester software release 43.200.031 or higher, and the resulting control unit software release is 0801 or higher. Programming uses the "Automatic programming" function in the rear axle steering control unit's Coding/programming menu and takes up to five minutes; the unit is re-coded automatically afterwards. Do not replace the right rear steering servo motor on the strength of C1445F2 alone until the software update has been applied and the fault memories cleared.

Typical repair cost:$0 - $300

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.

Typical repair cost:$400 - $4,000

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
