2025 GMC Hummer EV Lemon Law Case Study — Nevada
A Brand-New 2025 GMC Hummer EV Crippled by Super Cruise and Phantom Braking Defects
Our client leased a new 2025 GMC Hummer EV from an authorized Nevada GMC dealership in April 2025 — GM’s flagship electric super-truck, positioned as a showcase for the latest General Motors battery, software, and Super Cruise hands-free driving technology. The vehicle had just 87 miles on the odometer at lease signing. By 862 miles it was already back at the dealership for the first of six documented repair visits spanning more than five months.
Across those six visits, technicians diagnosed a failed front long-range radar module, performed multiple vehicle-wide module reprogrammings, replaced the infotainment radio module (later placed on backorder a second time), swapped the mobile telephone microphone and a front identification lamp for Bluetooth wind-noise failures, and opened tickets for unexplained automatic braking events at highway speeds. Despite all of this, Super Cruise continued to cut out, the touchscreen continued to freeze, and the vehicle continued to apply its own brakes without an obstacle in front of it.
What Went Wrong
- Super Cruise hands-free driving repeatedly unavailable: Failed front long-range radar module diagnosed, placed on backorder, replaced, and re-calibrated — yet the system continued to disengage on its own after full vehicle-wide reprogramming
- Unexpected automatic braking events: The truck applied its brakes on its own at both low speed and 45–50 MPH with no obstacle present — a safety-critical ADAS defect that technicians could not reliably duplicate or correct
- Infotainment freezing and navigation failure: Chronic touchscreen unresponsiveness, frozen navigation, and random phone disconnections — ultimately attributed to a defective radio module that remained on backorder
- Bluetooth and cabin acoustics: Excessive wind noise during phone calls at highway speed required replacement of the mobile telephone microphone and the front identification lamp, with callers still unable to hear the driver
- Rear cargo gate and swing gate defects: The rear gate repeatedly failed to open or close automatically; initial out-of-adjustment repair did not hold
- HVAC odor and performance: Foul A/C odor at startup plus loss of cooling after 20–25 minutes of driving — only partially addressed by enabling the HVAC afterblow function
Six Visits Could Not Resolve the Defects
Visit 1 — May 20–31, 2025 (11 Days)
- Swing gate would not close fully — dealer performed a rear door adjustment
- Super Cruise turning on and off after a few seconds — vehicle-wide programming performed; front long-range radar module diagnosed as failed and placed on backorder
- Infotainment screen and navigation slow to respond — radio updated and reprogrammed
- Foul odor noted from the A/C at startup; HVAC afterblow function later enabled
- Long-range radar sensor replaced and re-calibrated once the backordered part arrived
Visit 2 — June 23–30, 2025 (8 Days)
- Super Cruise reported as completely unavailable
- Multiple modules required updates; technicians performed a second full vehicle-wide programming sequence
Visit 3 — July 29–31, 2025 (3 Days)
- Infotainment freezing, callers unable to be heard on the phone, vehicle braking on its own, rear cargo gate failing to open or close
- Technicians were unable to duplicate all of the concerns during this visit
Visit 4 — August 2–5, 2025 (4 Days)
- Excessive wind noise during Bluetooth calls at highway speeds
- Steering wheel skip buttons reported inoperative; concern could not be duplicated
- Parts ordered for the Bluetooth/microphone issue
Visit 5 — August 14–20, 2025 (7 Days)
- Returned for Bluetooth wind-noise follow-up — front identification lamp and mobile telephone microphone replaced
- New complaints: intermittent phone disconnection, rear door that would not always close, navigation freezing and failing, unexpected automatic braking with no obstacle present, state of charge not updating in the app
- Navigation and charging issues attributed to a defective radio module — again placed on backorder
- Phone, rear door, and phantom braking concerns could not be duplicated by the dealer
Visit 6 — September 10–October 3, 2025 (24 Days)
- Client reported vehicle braking unexpectedly at both low speeds and 45–50 MPH — could not be duplicated
- Touchscreen intermittently unresponsive (with video documentation provided by client); radio software updated per GM TSB PIC6602H
- Knocking noise from the passenger side during acceleration and deceleration — could not be duplicated
- Random phone disconnections during calls, false parking sensor alerts, callers unable to hear the driver, A/C losing cooling after 20–25 minutes of driving
- At this point — six repair attempts and 57+ days out of service — a lemon law claim was the only viable path to a permanent remedy
Why This GMC Hummer EV Qualified for a Full Buyback Under Nevada Law
The 2025 GMC Hummer EV is GM’s flagship electric vehicle — sold and leased at a premium specifically because of its advanced battery, Super Cruise hands-free driving, and integrated infotainment platform. When those systems repeatedly fail, and the vehicle begins applying its own brakes without a driver input, the nonconformity strikes at every element of Nevada’s lemon law: use, market value, and safety.
This case presented several compelling legal factors:
- Nevada Lemon Law eligibility (NRS 597.600 – 597.680): Nevada protects buyers and lessees of new motor vehicles. A vehicle qualifies where the manufacturer cannot conform the vehicle to its express warranty after a reasonable number of attempts, or where the vehicle is out of service for a cumulative total of 30 or more days during the warranty term. This Hummer EV was documented out of service for at least 57 days across six repair events within the first year of the lease — nearly double the statutory threshold.
- Pattern of failed repairs on the same core systems: Super Cruise and infotainment were addressed on nearly every visit — module replacements, two full vehicle-wide reprogrammings, and a defective radio module on double backorder — and still could not be permanently repaired. That is a textbook substantial impairment pattern.
- Safety-critical phantom braking: Automatic braking events triggered without an obstacle present, at both low and highway speeds, go directly to the vehicle’s safety under Nevada law. The client’s contemporaneous video documentation strengthened the evidentiary record significantly.
- Lease framework does not weaken the claim: Nevada’s statute expressly covers lessees, and on a lemon lease the buyback unwinds the transaction — refunding down payment, monthly payments, taxes, and incidentals minus a mileage-based use allowance.
- Federal Magnuson-Moss Warranty Act: Repeated unsuccessful warranty repairs on a written-warranty nonconformity also triggered a federal breach-of-warranty claim, adding attorney-fee shifting pressure against General Motors LLC on top of the state remedy.
How Easy Lemon Secured a Full Vehicle Buyback
Free Case Evaluation
We reviewed the complete repair history and confirmed six separate documented service events for the same core Super Cruise, infotainment, and ADAS braking defects — all inside the first year of the Nevada lease.
Documentation & Case Building
Our team compiled every repair order, module replacement part number, GM TSB reference (including PIC6602H), backorder record, and the client’s video of the unresponsive touchscreen and phantom braking events into an airtight timeline showing GM’s inability to permanently repair the vehicle.
Demand to General Motors
We filed a formal demand against General Motors LLC citing Nevada’s Lemon Law (NRS 597.600 – 597.680) and the federal Magnuson-Moss Warranty Act — documenting six failed repair attempts, 57+ days out of service, and recurring safety-critical automatic braking events.
Full Vehicle Buyback
Easy Lemon successfully secured a $12,117 Vehicle Buyback from General Motors — the strongest possible outcome on a lemon lease. The manufacturer repurchased the defective Hummer EV, terminated the lease, and our client paid nothing out of pocket for legal representation.
