Three propulsion-loss recalls on the Hummer EV Pickup. CA owners with battery, drive unit, or charging issues may qualify for a buyback. Free review.
The GMC Hummer EV Pickup launched as the flagship of General Motors' electric vehicle renaissance — a 1,000-horsepower, three-motor monster with an MSRP north of $100,000 and marketing built around unstoppable capability. For a growing number of California owners, the reality has been a truck that couldn't be trusted to start, to hold its charge, or to stay on the road. The battery pack problems arrived almost immediately. Within a year of the first deliveries, GM issued recall 22V771 covering 824 early 2022–2023 units because the high-voltage battery pack enclosure was improperly sealed — water could enter and cause the truck to shut off or lose drive power. The remedy was a full battery pack replacement, a one-to-two day service event available only at GMC EV-certified dealers. A second battery recall followed in mid-2023: recall 23V367 covered 2022–2023 Hummer EV Pickup trucks whose battery module connections were out of position or improperly welded because a software update to end-of-line testing equipment had disabled the pass/fail logic. Again, the remedy was battery pack replacement. By 2024, a third major recall — 24V320 — targeted the rear drive unit itself: insufficiently insulated motor wires that could short-circuit and cut propulsion with no warning. That recall required a complete rear drive unit replacement, roughly six hours of labor. Throughout the same period, the Ultium software platform generated a steady stream of dealer reprogramming visits, warning messages, and failed OTA update attempts requiring full vehicle-wide module re-flashes. A 2025 TSB confirmed that door latch wiring connectors were corroding from water intrusion across the 2022–2025 model range. A 2026 model year airbag recall (25V769) rounded out a list of safety campaigns that spans every model year of this vehicle's production so far. California's lemon law exists for exactly this situation: a premium vehicle that has required multiple significant repairs — many of them for safety-critical systems — within the warranty period.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Airbag warning light may or may not illuminate; passenger-side airbag may not deploy in a frontal crash
Vehicle fails to start; loss of drive power while driving; high-voltage system warnings; water found in battery pack enclosure
Sudden loss of drive power; reduced propulsion warning; vehicle enters limp/reduced mode unexpectedly while driving
Sudden loss of drive power; warning lights; vehicle unable to accelerate or maintain speed
Vehicle fails to begin charging at public DC fast chargers; charge sequence does not initiate; high-voltage connector shows corrosion or water intrusion
Random warning messages on DIC; infotainment screen freezes or goes blank; surround-view cameras fail to load; software modules need reprogramming; OTA updates fail or require repeated dealer visits

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Vehicle fails to start; loss of drive power while driving; high-voltage system warnings; water found in battery pack enclosure
Safety recall involving complete vehicle inoperability and propulsion loss while driving — high lemon-law relevance. Multiple visits for battery replacement/diagnosis support substantial impairment and reasonable number of repair attempts arguments under CA Civil Code §1793.2.
HV battery pack replacement by GMC EV-certified dealer (1–2 day service); no charge to owner
Sudden loss of drive power; reduced propulsion warning; vehicle enters limp/reduced mode unexpectedly while driving
Sudden propulsion loss while driving is a serious safety defect. Battery replacement is a days-long service event. Repeat battery-related service visits (iss-01 and iss-02 both address battery pack) strengthen a lemon-law claim for substantial impairment and nonconformity.
HV battery pack replacement by GMC EV-certified dealer; no charge to owner
Sudden loss of drive power; warning lights; vehicle unable to accelerate or maintain speed
Complete drive loss is a safety defect. Drivetrain replacement is a significant service event. If combined with other Ultium electrical complaints, supports multiple nonconformities under CA lemon law.
Rear drive unit replacement by GM dealer (~6 hours labor); no charge to owner
Vehicle fails to begin charging at public DC fast chargers; charge sequence does not initiate; high-voltage connector shows corrosion or water intrusion
Charging failure renders an EV unusable for its primary purpose. While addressed via a satisfaction program rather than a safety recall, repeated DCFC failure visits support a substantial impairment argument for early 2022 owners.
Dealer applies additional RTV sealant (AC Delco) to HV connector under Customer Satisfaction Program N222360900; no charge to owner
Random warning messages on DIC; infotainment screen freezes or goes blank; surround-view cameras fail to load; software modules need reprogramming; OTA updates fail or require repeated dealer visits
Multiple software-related service visits at the dealer — especially if spread across 12 months or within 18,000 miles — strongly support a lemon-law claim under CA Civil Code §1793.2(d)(1) (2+ repair attempts for the same issue). Software defects that impair vehicle use, value, or safety qualify as nonconformities.
Full vehicle-wide module reprogramming at EV-certified dealer (SPS2 / Techline Connect); typically covered under warranty. Multiple service visits may be required.
One or both taillights fail to illuminate; taillights remain fully or partially on when they should be off; other drivers may misread vehicle signals
Safety lighting defect. Low unit count (10 vehicles) limits population exposure, but FMVSS noncompliance is per se safety defect. Relevant if owner experienced multiple taillight failures after initial repair.
Dealer inspection and replacement of left and/or right rear taillight assemblies; no charge to owner. All 10 affected vehicles repaired proactively by GMC prior to owner notification.
Seat belt buckle may feel loose; buckle may not retain occupant properly in a crash; no warning light for this condition
Safety recall. Small unit count (115 vehicles total across multiple models). Relevant if owner experienced this in combination with other defects; adds to repair-attempt count.
Dealer tightens left and right front seat belt buckle attachment bolts; no charge to owner
Airbag warning light may or may not illuminate; passenger-side airbag may not deploy in a frontal crash
Catastrophic safety defect — airbag non-deployment. Vehicles with airbag defects are per se safety nonconformities. 2026 Hummer EV Pickup owners with this issue may assert claim immediately upon recall notification given severity.
Dealer installs jumper harness with properly crimped connectors; no charge to owner. Notifications scheduled December 22, 2025.
'Service Door Latch' message on DIC; inoperative power windows, door locks, or outside mirrors; unwanted theft alarm activation; water intrusion at door
Recurring door latch and electrical faults that require multiple visits support a lemon-law claim for the same or substantially similar nonconformity. Door latch/lock failure is a functional safety issue (vehicle cannot be properly secured).
Dealer inspects and replaces corroded connectors per TSB 22-NA-144 procedure; covered under warranty if within coverage period
open
The front passenger airbag wire harness may have an improperly crimped terminal connection due to a supplier (Yazaki North America) equipment failure requiring manual crimping over a 3-day period. The improper crimp may interfere with deployment signals to the airbag.
closed
Electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a short and loss of drive power.
closed
Left or right front seat belt buckle attachment bolts may not be tightened to specification during assembly.
closed
Certain connections within the high-voltage battery pack may be out of position or not correctly welded due to a temporary software failure in end-of-line battery module testing equipment that disabled pass/fail logic.
closed
The high-voltage battery pack enclosure on certain 2022–2023 GMC HUMMER EV vehicles may not have been properly sealed due to flanges not being properly primed or electrocoated, preventing adequate urethane sealant adhesion. Water can enter the battery pack.
closed
Embedded software in the rear taillamp assembly microcontroller can cause one or both taillights to become inoperative or remain fully or partially illuminated. FMVSS No. 108 noncompliance.
Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act applies to new vehicles purchased or leased in California. It presumes a substantial defect exists when a manufacturer has made two or more unsuccessful attempts to repair a safety-related defect, or four or more attempts for any other defect, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. If your Hummer EV Pickup qualifies, you may be entitled to a full repurchase (purchase price less a mileage offset), a comparable replacement, or a negotiated settlement. GM is required to pay your attorney's fees if you prevail, meaning most California lemon law cases cost the owner nothing out of pocket. Given that the Hummer EV Pickup has been subject to three safety recalls involving propulsion loss — and that the remedy for two of those recalls was full battery or drivetrain replacement — owners with multiple service visits for power-loss or charging issues are strong candidates for a lemon law evaluation. The above is general information only and is not legal advice; results depend on the specific facts of your case.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
A 'could not duplicate' (CND) or 'no trouble found' (NTF) notation on your repair order still counts as a documented repair attempt under California law. Here is how to protect your record when the dealer cannot reproduce your problem: 1. Before every visit, write down the exact warning message or symptom, the date, time, mileage, recent driving or charging conditions, and whether any dashboard lights appeared. Capture video of the DIC if you can do so safely. 2. Ask the service advisor to retrieve and print all stored and historical Diagnostic Trouble Codes — not just codes that are currently active. Many Ultium-platform faults set a code, clear themselves, and then recur; the historical DTC log is the evidence. 3. Ask specifically whether the technician checked TSB PIT6065G, TSB 24-NA-143, and TSB 22-NA-144 against your symptoms. Reference them by number. 4. If your truck has an open recall and the dealer cannot perform the remedy because parts are on backorder, ask for that to be noted on the repair order. Days waiting for recall parts count toward the lemon law's 30-day out-of-service clock. 5. Keep every repair order — including CND visits, courtesy inspections, and parts-on-order hold visits. Each one is a documented repair attempt. 6. If the propulsion loss or battery issue is intermittent, note the ambient temperature, recent charge level, and whether you were accelerating hard — these details help technicians reproduce an Ultium-platform fault.
The 2022–2026 GMC Hummer EV Pickup is the most expensive and most recall-burdened vehicle on the Ultium platform. At over $100,000, owners are entitled to a truck that stays on the road. Instead, GM has issued three separate safety recalls for propulsion loss — two targeting the high-voltage battery pack and one targeting the rear drive unit — across virtually every model year of this vehicle. The software problems that have required repeated dealer reprogramming visits are documented across multiple TSBs. The water-intrusion issues that corrode door latches and contributed to the battery seal defect span five model years. Owners who have been back to the dealer twice or more for propulsion loss, charging failure, or the same recurring warning lights are in strong lemon law territory. A free case evaluation costs you nothing and could result in a full repurchase of the vehicle.

Has your GMC Hummer EV Pickup lost power on the road, failed to charge, or been back to the dealer for the same warning lights? If it has been subject to any of the battery or drivetrain recalls — 22V771, 23V367, or 24V320 — California law may entitle you to a full buyback or replacement vehicle. Get a free case review and find out where you stand.
Possibly yes. Two separate NHTSA safety recalls targeted the high-voltage battery pack on 2022–2023 Hummer EV Pickup trucks. Recall 22V771 (October 2022, 824 units) covered trucks whose battery pack enclosure was not properly sealed, allowing water to enter and cause propulsion loss or a no-start condition. Recall 23V367 (June 2023) covered trucks whose battery module connections were out of position or improperly welded because a software failure in GM's end-of-line testing equipment disabled the pass/fail logic. Both recalls required full high-voltage battery pack replacement at a GMC EV-certified dealer — a one-to-two day service event. Check your VIN at nhtsa.gov to confirm whether either recall is open on your specific truck.
Yes, and it is covered by multiple NHTSA safety recalls. Recall 22V771 documented at least one confirmed case of propulsion loss while driving due to a battery pack sealing failure. Recall 23V367 specifically identifies that vehicles 'may enter a reduced propulsion mode or lose propulsion' due to mis-welded battery module connections, increasing the risk of a crash. Recall 24V320 (May 2024) covers 2024 Hummer EV Pickup trucks whose rear drive unit motor wires were insufficiently insulated, causing a short circuit and sudden loss of drive power. If your truck lost power on the road — regardless of model year — document the date, mileage, speed, any warning messages on the DIC, and whether a tow was required. Each power-loss event and dealer visit for this issue counts toward a California lemon law claim.
NHTSA recall 24V320 (GM internal recall N242447080, May 2024) affects 2024 GMC Hummer EV Pickup trucks. The electric motors in the rear drive units may have insufficiently insulated wires that can contact each other, resulting in a short circuit and sudden loss of drive power. The remedy is replacement of the rear drive unit at no charge to the owner — approximately six hours of dealer labor. Owner notification letters were mailed June 24, 2024. The same recall also covered other 2024 Ultium platform vehicles including the Hummer EV SUV, Cadillac Lyriq, Chevrolet Blazer EV, Chevrolet Silverado EV, and GMC Sierra EV. If you own a 2024 Hummer EV Pickup and have not had the rear drive unit replaced, contact your GMC dealer and check nhtsa.gov for your VIN's open recall status.
Yes. The 2022–2024 Hummer EV Pickup is covered by multiple GM technical service bulletins (TSBs) addressing software instability across the Ultium platform. TSB series PIT6065 (revisions A through H, October 2023 to June 2024) directed dealers to check all electronic modules for software updates using the SPS2 system. TSB 24-NA-143 required comprehensive vehicle-wide module programming as a prerequisite to subsequent customer satisfaction programs. These procedures are covered under warranty or the applicable GM customer satisfaction program — no charge to the owner. Symptoms addressed include random warning messages on the Driver Information Center, infotainment screen freezes, surround-view camera failures, and repeated OTA update failures. If your dealer has reprogrammed your truck's modules more than once, or if the same warning messages return after reprogramming, those visits collectively support a California lemon law claim.
You may qualify. California's Song-Beverly Consumer Warranty Act presumes a substantial defect when a manufacturer has made two or more unsuccessful repair attempts for a safety-related defect, four or more attempts for any other substantial defect, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. The Hummer EV Pickup's recall history — three separate campaigns for propulsion loss (22V771, 23V367, 24V320) and multiple TSBs requiring dealer reprogramming — means owners who have made multiple service visits for power-loss or charging issues are strong candidates. Each recall remedy visit (battery pack replacement, drive unit replacement) is a multi-day event that counts toward the 30-day clock. If you prevail, GM pays your attorney's fees. Most California lemon law cases cost the owner nothing out of pocket. This is general information and not legal advice; results depend on the specific facts of your case.
GM issued TSB 22-NA-144 in February 2025 specifically to address this symptom on 2022–2025 Hummer EV Pickup trucks. The root cause is water intrusion at the door latch wiring connectors. Water causes corrosion on the connector terminals, which leads to intermittent or permanent failure of the door latch electronics — producing the 'Service Door Latch' message on the Driver Information Center and also causing power windows, door locks, and outside mirrors to stop working. False theft-alarm activations are also associated with this fault. The TSB directs dealers to inspect the door latch wiring connectors and replace any that show corrosion. If the condition recurs after a dealer repair — as it may, given the underlying water management issue on the Hummer EV platform — each visit for the same problem adds to your documented repair-attempt count under California lemon law.
