NHTSA recall 26V-281 covers certain 2024-2026 platform-192 AMG GT vehicles whose infotainment-control-unit software may trigger increased system resets. During a reset, the instrument cluster may briefly stop displaying driving-related information, increasing crash risk. The report lists 144,049 vehicles across all included Mercedes model lines; that total is not an AMG GT owner-report count.
brief interruption of driving information in the instrument cluster
infotainment system reset under the recalled software condition
VIN identified in campaign 2026050004
How to Fix
Check the VIN for open Mercedes campaign 2026050004. An authorized Mercedes-Benz dealer updates the infotainment control-unit software on affected vehicles. Do not buy a display, battery or control unit from this page; the official remedy is VIN-controlled software unless separate diagnosis establishes an unrelated hardware fault.
The AMG GT 63 S E Performance is a plug-in hybrid and is a fundamentally different electrical architecture from every other GT — it carries a high-voltage battery and a high-voltage starter-alternator on top of the M177 V8. NHTSA campaign 25V129000 covers 2023-2024 and 2025 AMG GT 63 S E Performance four-door coupes (alongside GLC 63 S E Performance, S 63 E Performance and SL 63 S E Performance) for a software error that can cause the high-voltage starter-alternator control unit to fail, resulting in a loss of drive power. This is not the 48V EQ Boost ISG issue of the GT 43/53 and not a 12V fault; it is the HV traction-side starter-alternator on the E Performance powertrain only, and it must not be attributed to the non-hybrid GT 63.
Common Symptoms
Sudden loss of drive power
Hybrid or drivetrain malfunction warning
Vehicle enters reduced-power mode
Failure to start on electric drive
How to Fix
Free recall remedy: the dealer updates the high-voltage starter-alternator control unit software under 25V129000. Because the remedy is software, it is quick and there is no reason to defer it. Owners can confirm applicability by VIN at nhtsa.gov/recalls or through MBUSA customer service. If drive power has already been lost once, have the fault memory read before the update so the event is documented — the reflash clears the evidence.
On the X290 four-door AMG GT (GT 43 / GT 53), the transmission wiring harness can be routed incorrectly so that the electrical connector sits where it is exposed to water and road spray. The connector corrodes, and the corroded contacts can short-circuit — which Mercedes-Benz itself describes as increasing the risk of fire, and which can also strand the car with transmission fault messages. NHTSA campaign 22V533000 covered 2019-2022 GT 53 and 2021-2022 GT 43. That remedy did not hold: campaign 24V445000 was opened afterward for 2019-2025 GT 53 and 2021-2024 GT 43 because the harness connection 'might not have been correctly wired during a prior recall repair or during production' — meaning cars that already had the first recall performed can still be defective. This is a four-door X290 issue tied to the 9G-TRONIC installation and does not transfer to the C190 two-door's rear transaxle DCT.
Common Symptoms
Transmission fault or limp-home message
Intermittent shifting faults that come and go with weather
Burning-plastic smell from under the vehicle
Corroded green residue on transmission harness connector
How to Fix
Free recall remedy. Under 22V533000 the dealer inspects and repairs the connector, reroutes the harness and installs a retaining bracket. Under the superseding 24V445000 the dealer replaces the two-part wiring harness and the connector outright — the more durable fix. Do not accept 'recall already done' as closing this out on a GT 43/GT 53: check the VIN specifically against 24V445000, since that campaign exists precisely to catch cars the earlier repair left wrong. If the car is showing intermittent transmission faults, have the connector inspected for green corrosion before any transmission control unit is condemned.
The GT 43 and GT 53 use the M256 inline-six with a 48-volt EQ Boost integrated starter-generator that replaces the conventional starter and alternator. Two distinct failures cluster here. First, a safety defect: NHTSA campaign 24V100000 covers 2021-2023 GT 43 and GT 53 whose 48-volt ground cable connection was not tightened to specification — a high-resistance ground on a 48V circuit overheats, with fire risk. Second, and far more common in owner reports, the 48V lithium battery and the ISG itself fail. Because the ISG is the starter, a failed 48V battery is not a degraded-performance condition the way a weak 12V battery is: the car simply will not crank, typically after a '48V onboard electrical system malfunction' or hybrid-battery-depleted warning. Owners on MBWorld discuss this specifically for GT 43/GT 53. This is distinct from ordinary 12V drain — it is the 48V subsystem, it is M256-specific, and it does not exist on the M177/M178 V8 GT 63 or on the C190 two-door.
Common Symptoms
48V onboard electrical system malfunction message
Vehicle will not crank or start at all
Loss of stop/start and EQ Boost torque fill
Intermittent check engine light with hybrid battery depleted fault
Overheated or discolored 48V ground cable terminal
How to Fix
For the ground cable, a free recall remedy exists: under 24V100000 the dealer inspects and tightens the 48-volt ground cable connection. For the battery/ISG failure there is no recall — the 48V lithium battery is replaced as a part (it lives under the passenger seat or in the trunk area depending on build), and a failed integrated starter-generator is a much larger job requiring belt-drive/front-accessory access. Diagnose before parts-swapping: a bad 48V ground or a corroded 48V connector produces the same no-start and the same malfunction message as a dead 48V battery, and the ground is the cheaper thing to rule out first.
On 2019-2021 AMG GT 63 and GT 63 S four-door models (sharing the recall with the 2018-2021 E63 S), the starter motor positive cable was not installed correctly at the factory. The misposition lets the power-supply harness wires chafe against adjacent structure. Once the insulation wears through, the exposed conductor on an unfused battery-positive feed can short — Mercedes-Benz's own defect description cites both a vehicle stall (crash risk) and a fire risk. NHTSA campaign 21V217000 covers it; MBUSA's internal campaign number is 2021040013 and owner letters were mailed May 18, 2021. This is the M177 V8 four-door population; the parallel electrical fire recall on the six-cylinder GT 43/53 cars is the separate 48V ground cable campaign, and the two should not be conflated.
Free recall remedy: the dealer inspects and, as necessary, corrects the screw connections and the routing position of the positive cable under 21V217000. There is no parts replacement in the base remedy unless chafe damage is already present, in which case the damaged harness section must be repaired or replaced — insist on an actual visual inspection of the conductor rather than a torque check alone if the car has any history of intermittent electrical faults or unexplained stalls.
Mercedes' current electronic architecture (shared across the C192 AMG GT, W206 C-Class, X254 GLC, and EQE/EQS) has documented 12V battery drain complaints from control modules not sleeping properly — typically the telematics / mbrace head unit polling cellular at idle. On the AMG GT specifically, there's no model-specific TSB yet, but the same root cause applies: cars left parked for 1-2+ weeks may need a jump-start, and battery management warnings can appear on the cluster. The W206 has a TSB (LI54.10-P-076820); EQE/EQS got a 2024 software recall (24V-372). Typical remedy on AMG GT is a software update at the dealer or, if the battery has been damaged by repeated deep discharge, replacement (~$400-600 for the AGM unit). Most cases are nuisance-level; severity downgraded from medium to low for that reason.
Perform a parasitic draw test after the vehicle times out, then scan all body, telematics, and gateway modules for wake-up events or software faults. Dealers often address this with software updates, battery testing/replacement, and in some cases replacement of a module that remains awake. Owners who store the car or drive infrequently often use a maintainer to prevent repeat discharge while the root cause is being resolved.

The in-tank fuel pump fitted to a broad range of 2021-2024 Mercedes-Benz models including the AMG GT uses an impeller that did not meet material specification. The impeller swells or deforms in service, contacts the pump housing and binds. The mechanical resistance shuts the pump down, and the vehicle loses propulsion without warning — the car will not restart afterward. Mercedes-Benz's Part 573 report notes that before a full stall the engine may run rough and warning lamps may illuminate, which is the only advance notice an owner gets. NHTSA campaign 23V880000 covers more than 87,000 vehicles across GLE, GLS, C-, E-, S-, SL-, GLC-, CLS-Class, G-Class and AMG GT. Because MBUSA issued an interim notice in February 2024 before the final remedy was ready, a number of owners were told their car was defective months before a fix existed, and some cars were stalled in the interim.
Engine stalls without warning and will not restart
Rough running before shutdown
Fuel system warning lamp illuminates
Loss of propulsion while driving
How to Fix
Free recall remedy: the dealer replaces the fuel pump under 23V880000. Interim owner letters went out February 13, 2024 with a second notice once the remedy parts were released, so a car whose only paperwork is the interim letter has NOT been repaired. Verify the VIN at nhtsa.gov/recalls and confirm the pump was actually replaced rather than merely inspected. Treat a rough-running condition or a sudden fuel-system warning on an affected car as urgent rather than as a routine drivability complaint — the documented failure mode ends in an unrestartable stall.
NHTSA campaign 21V961000 covers 2019 AMG GT 53 and AMG GT 63 four-door models and calls for replacement of the fuel rail together with the fuel injectors. A defective high-pressure rail or injector interface on a direct-injection engine leaks fuel into the engine bay under pressure, adjacent to hot turbocharger and exhaust components. This is separate from the later 23V880000 in-tank pump recall — different component, different failure, different model years — and it is confined to a narrow 2019 build population on the X290 four-door. It affects both the M256 inline-six GT 53 and the M177 V8 GT 63, so it is not a single-engine issue, but it is a single-model-year issue and should not be extrapolated to 2020 and later cars.
Visible fuel seepage at the fuel rail or injector seats
Hard starting or rough idle
Check engine light
How to Fix
Free recall remedy: the dealer replaces the fuel rail and fuel injectors under 21V961000. Because this is a fuel-leak defect near hot components, an affected 2019 GT 53/GT 63 showing a fuel smell should not be driven until inspected. Verify completion by VIN — this campaign is old enough that used cars change hands with it still open, and a used-car listing's clean history report is not a substitute for the NHTSA lookup.
The C190/R190 two-door AMG GT does not use a torque-converter automatic. It uses a rear-mounted Getrag/Magna 7DCL750 seven-speed dual-clutch transaxle — the same family as the Ford GT unit — and it is the single most expensive failure point on the car. Owner and specialist reports converge on a consistent set of failure modes: clutch pack wear producing shudder or hesitation on take-up, internal speed sensor failures throwing transmission control faults, oil weeping from the transaxle case weep holes, and seal/gasket leaks. Forum threads document malfunction codes tied to the electronic transmission control and DCT-specific CCP and SAP faults. The unit is intolerant of missed service: it demands strict fluid intervals and Mercedes-approved fluid, and abnormal vibration or slow engagement is the documented early warning that the gearbox is going. Because the transaxle sits at the rear of a torque tube, access is poor and labor is heavy. This is entirely distinct from the X290 four-door's front-mounted 9-speed AMG SPEEDSHIFT TCT.
Common Symptoms
Shudder or judder when pulling away from a stop
Slow or hesitant gear engagement
Transmission malfunction warning message
Unusual vibration through the drivetrain
Oil weeping from the transaxle case
Harsh or missed shifts
How to Fix
Keep the 7DCL750 service current and investigate take-up shudder immediately. The service kit is appropriate for scheduled/overdue maintenance; a unit with clutch, speed-sensor, seal or pressure faults needs a transmission specialist and may require a rebuild.

The C190 AMG GT mounts its rear transaxle on three ACTIVE (electronically controlled) mounts that stiffen under hard cornering and soften at idle. The most common reported failure isn't rubber breakdown — it's wiring harness or connector corrosion at the mount sensors, which trips dash warnings ("Suspension malfunction" / "Engine/transmission mount fault") and forces the mounts into a default-soft state. The fix is usually harness cleaning or connector replacement; full mount replacement is uncommon but expensive when needed (active mounts are pricey OEM parts and labor at the rear of the car is significant). The original entry incorrectly described these as passive hydraulic mounts.
Common Symptoms
Clunk when shifting gears
Vibration through cabin at low speed
Harsh engagement when going from park to drive
Drivetrain shudder during acceleration
How to Fix
Replace the transaxle mounts with updated Mercedes parts. Inspect the torque tube bearing simultaneously. Use OEM mounts unless the car is tracked, in which case solid mounts from aftermarket suppliers may be preferred.

NHTSA campaign 22V042000 covers the 2021 AMG GT Black Series specifically for a front wheel speed sensor wiring harness defect, remedied by replacing the harness. The Black Series is the only GT with the M178 LS2 flat-plane-crank version of the 4.0L twin-turbo V8 and carries unique front-end aero and chassis hardware, and this campaign does not extend to the GT R, GT R Pro or any other C190 variant. Loss or corruption of a front wheel speed signal disables or degrades ABS, ESP and traction control simultaneously, because all three consume the same sensor data — on a 720 hp track-focused car with carbon-ceramic brakes and no stability net, that is a serious condition. The very small production volume of the Black Series means this issue is easy to miss in aggregate model-level problem data, which is exactly why it needs its own record.
Common Symptoms
ABS warning lamp
ESP/traction control disabled message
Speedometer or wheel speed signal dropout
Erratic ABS activation
How to Fix
Free recall remedy: the dealer replaces the front wheel speed sensor wiring harness under 22V042000. Because Black Series cars are frequently low-mileage collection or track vehicles that sit and skip dealer visits, this campaign has a higher-than-typical chance of being open — verify the VIN at nhtsa.gov/recalls rather than assuming a nearly-new car is clear. If ABS/ESP lamps have appeared and the harness has not been replaced, do not let a shop condemn the sensor itself before the harness is inspected.
NHTSA campaign 20V395000 covers 2019-2020 AMG GT vehicles that left the factory with an incorrect Electronic Stability Program software version installed. With the wrong calibration, the ESP system can react inaccurately — intervening when it should not, or failing to intervene correctly during a loss-of-traction event. On a rear-biased, high-output car this is a meaningful stability and braking-intervention defect rather than a convenience fault, and it is invisible to the owner because the system reports no error: the software is present and running, it is simply the wrong version for the vehicle. Nothing about this is diagnosable from the driver's seat, which is why VIN verification matters more here than on failures that announce themselves.
Common Symptoms
ESP intervening unexpectedly or inappropriately
Inconsistent stability control behavior in low-grip conditions
No warning lamp despite incorrect calibration
How to Fix
Free recall remedy: the dealer updates the ESP control unit software to the correct version under 20V395000. There is no hardware component to this repair. Because the defect produces no warning lamp, an owner cannot rule it out by the absence of symptoms — the only way to know is a VIN lookup at nhtsa.gov/recalls. This campaign is frequently still open on used cars precisely because nothing ever prompted the first owner to act on it.
On the C190/R190 two-door AMG GT, engine torque reaches the rear-mounted transaxle through a carbon-fiber torque tube driveshaft that is bonded — not bolted — to its metal end flanges. Production residue left on the bonding surfaces impaired the adhesive joint, so the bond can progressively fail and the shaft can spin free of or separate from the flange. The result is a sudden, total loss of drive with the engine still running, and in a worst case a liberated shaft inside the tunnel. Mercedes-Benz never got this right on the first attempt: NHTSA campaigns 16V308000, 19V457000 and 21V478000 all cover the same carbon-fiber driveshaft bond on overlapping 2016-2018 build windows, with the 2019 campaign covering cars built July 8, 2015 through March 22, 2017. Because the same VIN can fall under more than one campaign, an owner who had the earlier inspection done is not automatically clear of the later one. This is specific to the M178 two-door GT/GT S architecture and does not apply to the X290 four-door GT 43/53/63, which uses a conventional front-mounted 9-speed and steel/aluminum driveshaft.
Common Symptoms
Sudden loss of drive power while engine continues to run
Clunk or bang from the center tunnel under load
Driveline vibration or shudder under acceleration
Metallic knocking from the torque tube area
How to Fix
Free recall remedy exists and it is the only correct fix: an authorized Mercedes-Benz dealer replaces the carbon-fiber driveshaft including the flange (16V308000 and 21V478000 are inspect-and-replace-as-necessary; 19V457000 is outright replacement of shaft plus flange). Run the VIN through the NHTSA recall lookup against all three campaign numbers rather than assuming one closes the others — this defect was re-opened twice because the earlier inspection criteria were inadequate. Any pre-purchase inspection on a 2016-2018 GT/GT S should include recall-completion evidence for each campaign.
The 2024+ AMG GT uses rear-axle steering and a dense network of chassis sensors tied into stability control and driver assistance systems. Early-owner reports describe warning messages for steering assist, ESP, or driver assistance functions, sometimes after alignment work, low battery events, or software glitches. In many cases the hardware is intact, but calibration values or sensor initialization are lost or out of range.
Scan the steering, ESP, and rear-axle steering modules for stored faults, then verify alignment and ride-height values before recalibrating steering-angle and chassis sensors. Dealers commonly perform software updates and guided calibrations; if faults return, they inspect wheel-speed sensors, steering rack/rear-steer actuators, and wiring. A low-voltage event should be ruled out first because it can trigger multiple false chassis warnings.
The AMG GT has been recalled repeatedly across its entire production run for defects in the telematics communication module that carries the emergency call function, and the campaigns stack across different root causes rather than repeating one. NHTSA 21V058000 covers 2016-2021 AMG GT for emergency call system software; 21V072000 covers 2017-2021 for a communication module that may not be activated; 19V787000 covers 2016 model years for eCall software; and 22V365000 covers 2017-2022 AMG GT-Class for a communication module SIM card defect. The common consequence is that after a crash the vehicle may fail to transmit the automatic emergency call, or may transmit an incorrect vehicle location to the responder — a silent failure the owner has no way to detect, since the system gives no indication it is inoperative until it is needed. Note this is the telematics/eCall path, entirely separate from the later instrument-cluster reset recall.
Common Symptoms
SOS or emergency call system fault message
Mercedes me connected services unavailable
No response when the SOS button is pressed
Incorrect vehicle location reported by connected services
How to Fix
Free recall remedies exist and most are software: 21V058000 and 22V365000 update the communication module software either over the air or at a dealer; 21V072000 has the dealer inspect and activate the communication module. Owners should check the VIN at nhtsa.gov/recalls against all applicable campaign numbers, since a car built across a boundary year can be subject to more than one. An over-the-air update only lands if the vehicle is connected and the Mercedes me account is active — cars that have sat, changed hands, or had their connected services lapse are the ones most likely to still be unremedied, and they should be taken to a dealer rather than left to update themselves.
The wheel-hub center caps on 2019-2020 AMG GT 53 4MATIC+ and AMG GT 63 4MATIC+ four-door coupes were not manufactured to specification. The fastening clip mechanism cannot withstand the stresses induced in normal driving, and the cap detaches from the wheel hub while the vehicle is moving. A cap released at highway speed becomes a projectile and a road hazard for following traffic — NHTSA campaign 20V800000 frames the risk as a crash or injury hazard to other road users rather than to the occupants. MBUSA's internal number is 2021030014 and owner letters were mailed May 7, 2021. This is an X290 four-door issue and is not documented on the C190 two-door.
Common Symptoms
Missing wheel center cap
Rattle or buzz from a wheel at speed
Loose or cracked hub cap clips
How to Fix
Free recall remedy: the dealer replaces the wheel-hub caps under 20V800000. This is a cheap, fast repair that is very often left open because a missing hubcap reads as cosmetic — owners who have already lost one or more caps and bought replacements over the counter may still have unmodified caps on the remaining wheels. Check all four, and check the VIN, rather than assuming the loss of a cap was a one-off.
