    On the 2025-2026 Chevrolet Corvette 5.5L LT7 twin-turbo V8, gM issued NHTSA recall 25V536 (GM number N252514930) covering 2025-2026 Corvette ZR1 with the twin-turbo 5.5L LT7 and 2023-2026 Corvette Z06 with the 5.5L LT6, about 23,656 vehicles in total. On these cars excess fuel can spill into the fuel-filler pocket during refueling and drain onto an ignition source - the left-side radiator/fan package unique to the LT6/LT7 cooling layout, whose fans can run even with the engine off, plus hot brake rotors - creating a fire risk. Fitment is defined by that left-side radiator/fan combination: the Corvette Stingray and the E-Ray do not have it and are not covered by this recall. GM also placed a stop-sale on unsold 2025-2026 Z06 and ZR1 units, and only 108 ZR1s were affected in the initial 2025 population.

    Common Symptoms

    • Fuel spilling or pooling in the fuel-filler pocket while refueling
    • Strong fuel smell after filling up
    • Fuel dripping onto the ground behind the left front wheel after refueling

    How to Fix

    Check your VIN at nhtsa.gov/recalls or with a Chevrolet dealer for campaign 25V536 and have the free remedy performed - dealers install an insert/shield that redirects spilled fuel away from the ignition sources. Until the shield is installed, make sure the fuel nozzle is fully inserted into the filler pipe, never top off after the pump's first automatic shut-off click, and do not overfill the tank.

    On the 2023-2026 Chevrolet Corvette, gM recalled 2023-2026 Corvettes built with a left-side radiator/fan combination because excess fuel can spill into the fuel-filler pocket during refueling and drain onto an ignition source. On the mid-engine C8 the filler pocket sits directly above hot engine and exhaust hardware, so spilled fuel that escapes the pocket lands on components hot enough to ignite it. NHTSA received a complaint from a 2023 owner describing exactly this outcome: as the fuel nozzle was pulled from the vehicle a violent explosion occurred and the owner was immediately engulfed in a fireball. Owner notification letters for recall 25V536000 went out November 14, 2025. Because the recall is keyed to a specific radiator/fan configuration rather than a build date range, VIN lookup is the only reliable way to know whether a given car is included.

    Common Symptoms

    • Fuel pooling in the fuel-filler pocket during refueling
    • Raw fuel smell after filling the tank
    • Fuel dripping down the rear quarter after refueling
    • Fire or flash ignition at the pump

    How to Fix

    Run your VIN at nhtsa.gov/recalls or through a Chevrolet dealer against campaign 25V536000. The remedy is free: the dealer installs a shield that diverts spilled fuel away from the ignition source. Until the shield is fitted, refuel deliberately — do not top off after the pump clicks, keep the nozzle fully seated, withdraw it slowly and let it drain, and avoid filling immediately after a hard drive when exhaust and engine temperatures are at their peak. If you see fuel pooling in the filler pocket or smell raw fuel after filling, do not start the car; let it evaporate first. Chevrolet customer service for this campaign is 1-800-222-1020.

    On the 2025-2026 Chevrolet Corvette 5.5L LT7 twin-turbo V8, gM has placed the 5.5L twin-turbo LT7 in the 2025-2026 Corvette ZR1 - and the naturally aspirated 5.5L LT6 in the 2023-2026 Z06 - on a Technical Assistance Center part restriction, published as #PIP6089 and highlighted in GM TechLink. A part restriction means a dealer cannot simply order a replacement engine: when diagnosing a possible engine failure the technician must gather the information required by PIP6089, including the engine part number stamped on the center of the front cover, and open a case with TAC before an engine is released. GM frames this as continuous improvement, but the stated cause on the restriction is 'possible engine failure,' and the January 2026 update to PIP6089 adds instructions for handling catastrophic failure cases and intake manifold transfer, which indicates real field failures are being worked. Owners have reported LT7 engine failures during track use at low mileage.

    Common Symptoms

    • Sudden loss of power or engine shutdown at speed
    • Knocking or mechanical noise from the engine
    • Smoke from the engine compartment and/or oil leak after failure
    • Dealer unable to order a replacement engine without a TAC case

    How to Fix

    If the ZR1 shows a sudden power loss, knocking, smoke or a hard shutdown, stop driving it and have it flat-bedded to a Chevrolet dealer. Make sure the dealer opens a TAC case under #PIP6089 rather than attempting an out-of-process engine order, and keep all track-use, oil-change and fuel records - GM Brand Quality reviews returned engines and requires that all internal components be returned with a warranty engine. Do not accept a replacement engine install that reuses the original intake manifold if the failure scattered debris: GM's own bulletin (#00-06-01-026) states the ultrasonically welded plastic manifold cannot be fully cleaned and must be replaced, or the debris will destroy the new long block.

    On the 2025-2026 Chevrolet Corvette, a lighting control module software error introduced in October 2024 leaves 2025 and 2026 C8 Corvettes unable to detect and report a failed rear turn signal, which is an FMVSS noncompliance. The driver receives no telltale when a rear turn signal bulb or LED circuit stops working, so the car can be driven indefinitely signaling to nobody behind it. NHTSA identified the consequence as increased crash risk because the driver does not know the signal is out. What began as a quiet dealer stop-sale on roughly 3,300 cars expanded into NHTSA recall 26V213000 covering approximately 32,988 vehicles — effectively the entire 2025 and 2026 C8 population across Stingray, Z06, E-Ray and ZR1 variants. Owner notification is scheduled for May 18, 2026.

    Common Symptoms

    • No warning message when a rear turn signal fails
    • Rear turn signal inoperative with no cluster indication
    • Hyper-flash or outage telltale does not appear

    How to Fix

    Check your VIN against campaign 26V213000 at nhtsa.gov/recalls or through a Chevrolet dealer. The remedy is a free lighting control module software update, delivered either over-the-air or at a dealer depending on the vehicle — 2025 cars generally require a dealer visit. Until the update is applied, physically verify your rear turn signals rather than relying on the cluster: have someone stand behind the car while you cycle both signals and the hazards, and repeat the check periodically. Do not interpret the absence of a warning message as confirmation the lamps work, because that is precisely the function this defect disables.

    On the 2024-2026 Chevrolet Corvette 6.2L LT2 V8 with front eAWD hybrid drive unit, stealth Mode (electric-only driving up to about 45 mph) and Shuttle Mode are the E-Ray's headline hybrid features, and owners frequently report the car refusing to enter them with an 'unavailable' message in the Driver Information Center. GM addressed this first with diagnostic tip #PIC6542 for the 2024 Corvette E-Ray, then superseded it with Bulletin #25-NA-374, 'Stealth and/or Shuttle Modes Unavailable,' covering 2024-2026 E-Ray (and ZR1X) models. In many cases the behavior is by design - the modes are gated by high-voltage battery state of charge, ambient temperature and accessory load - but GM's repeated republishing of the bulletin means a dealer should confirm whether the specific car meets the enabling conditions or has an actual fault before any parts are replaced.

    Common Symptoms

    • 'Stealth Mode Unavailable' or 'Shuttle Mode Unavailable' message in the Driver Information Center
    • Car will not launch or drive on electric power only
    • Electric-only range far shorter than the advertised ~4 miles
    • Mode drops out when climate control or defroster is switched on

    How to Fix

    Before assuming a defect, verify the enabling conditions: adequate high-voltage battery state of charge, warm enough ambient temperature, and climate control/defroster demand low. If the modes remain unavailable when conditions are met, have the dealer apply Bulletin #25-NA-374 (which replaces #PIC6542A) - it defines the normal-operation criteria and the diagnostic path. Refuse parts replacement until the bulletin's criteria have been checked, since a large share of these complaints are normal operation rather than a failure.

    On the 2024-2026 Chevrolet Corvette 6.2L LT2 V8 with front eAWD hybrid drive unit, on the E-Ray only, the 8-speed dual-clutch transmission carries an auxiliary fluid pump so the gearbox stays pressurized while the car is moving on electric power alone in Stealth or Shuttle mode. GM published Bulletin #25-NA-278 for 2024-2026 Corvette E-Ray models that display a Service Transmission message in the Driver Information Center along with an illuminated Check Engine MIL, with DTC P1955 (Transmission Fluid Pressure Relief Valve Performance) and/or P0867 (Transmission Fluid Pressure Performance) stored in the TCM. GM identifies the cause as auxiliary pump cavitation traced to the transmission pan fluid filter. This condition is specific to the hybrid E-Ray driveline and does not apply to the Stingray, Z06 or ZR1, which have no electric-only drive mode and no auxiliary pump duty cycle of this kind.

    Common Symptoms

    • Service Transmission message in the Driver Information Center
    • Check Engine light (MIL) illuminated
    • DTC P1955 and/or P0867 stored in the transmission control module
    • Condition often noticed after driving in Stealth or Shuttle mode

    How to Fix

    Scan the TCM for P1955 and P0867 as current or history codes. Per Bulletin #25-NA-278, replace the transmission fluid pan filter and re-evaluate the vehicle - GM explicitly directs that no other repairs be attempted for these DTCs. The 15 transmission pan bolts are single-use fasteners and must be replaced and torqued in sequence with a GM-45059-A angle meter per the service information. Most affected cars are still inside the powertrain warranty, so have the work done at a Chevrolet dealer under the bulletin.

    On the 2024-2026 Chevrolet Corvette 6.2L LT2 V8 with front eAWD hybrid drive unit, the E-Ray's front axle is driven by an electric drive unit (RPO HP1) that contains a drive motor disconnect clutch and its actuator; the clutch decouples the front motor at higher speeds and re-engages it for eAWD launch and traction. GM released Bulletin #25-NA-266 covering all 2024-2026 Corvette E-Ray models for an illuminated MIL with DTC P2DE6 set for Drive Motor Clutch Actuator Performance. Because this component exists only in the E-Ray's front electric drive unit, the fault cannot occur on Stingray, Z06 or ZR1. GM has also published Bulletin #24-NA-118 describing available component-level repairs for the HP1 front electric drive unit, indicating the unit is serviceable rather than replace-only.

    Common Symptoms

    • Check Engine light (MIL) illuminated
    • DTC P2DE6 - Drive Motor Clutch Actuator Performance
    • Loss or intermittent loss of front-axle electric assist / eAWD
    • Reduced launch performance

    How to Fix

    Have a Chevrolet dealer confirm DTC P2DE6 in the drive motor control module and follow Bulletin #25-NA-266. Do not let a shop condemn the whole front electric drive unit before checking Bulletin #24-NA-118, which lists the repairs available on the HP1 front drive unit - a component-level repair is often possible instead of a full unit replacement. High-voltage service on this system requires GM-trained technicians and the proper de-energizing procedure; this is not a DIY repair.

    Typical repair cost:$600 - $5,000
