GMC Sierra 2500HD: tailgate, steering, fire & transmission recalls. If repairs haven't held, CA lemon law may entitle you to a repurchase or replacement.
The GMC Sierra 2500/3500 HD with the 6.6L L8T gas V8 is built to haul, tow, and work hard — but owners of 2020-2026 model years have accumulated thousands of NHTSA complaints and faced multiple federal safety recalls. Whether your Sierra HD's tailgate swings open while you're doing 60 on the freeway, your steering went suddenly dead in a 2024 model, or your truck stubbornly flashes 'Shift to Park' every time you try to shut it off, these are not random gremlins. They are documented, recurring defects that General Motors was aware of — and in many cases already under federal recall for. If your truck has spent meaningful time at the dealership for the same problems and GM still hasn't made it right, California's lemon law may give you powerful options: a replacement vehicle, a cash repurchase, or a civil penalty if GM knew and stalled.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Sudden loss of steering; steering wheel becomes unresponsive or disconnected; vehicle cannot be steered
Smoke or burning smell from engine bay; dashboard warning lights; potential underhood fire; vehicle must be parked outside as precaution
Tailgate opens on its own while driving or after parking; cargo falls out of truck bed; tailgate fails to latch or releases without input
Dashboard shows 'Shift to Park' message even when transmission is in Park; ignition will not turn off until message clears; intermittent, may require multiple attempts to shut vehicle off
Seat belt in front-row center position may not secure properly; belt hardware loose; potential for belt to detach in a collision
Harsh or jerky gear changes; delayed shift into reverse; slipping between gears; check-engine or transmission warning light; limp mode activation; transmission overheating message

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Tailgate opens on its own while driving or after parking; cargo falls out of truck bed; tailgate fails to latch or releases without input
194,266+ GMC units recalled; recurring across 2020-2024 MYs; cargo-loss/crash hazard qualifies as a serious safety defect. Two separate recall campaigns signal persistent non-conformity ideal for substantial-impairment argument.
Dealer replaces exterior touchpad switch assembly at no charge under NHTSA recalls 24V060 and 24V894
Sudden loss of steering; steering wheel becomes unresponsive or disconnected; vehicle cannot be steered
Complete loss of steering constitutes a catastrophic safety defect. Even with low affected-unit count (~1,888 GMC units), a single unrepaired occurrence on a lemon-law vehicle is highly probative of substantial impairment.
Dealer inspects and replaces the steering gear assembly at no charge under recall 23V549
Smoke or burning smell from engine bay; dashboard warning lights; potential underhood fire; vehicle must be parked outside as precaution
Vehicle fire risk is a per se safety defect under California lemon law. Pre-repair advisory to park outside shows GM acknowledged imminent danger. Any delay in repair while defect was known strengthens the claim.
Dealer replaces BPMV assembly at no charge; owners advised to park outside until repair completed
Dashboard shows 'Shift to Park' message even when transmission is in Park; ignition will not turn off until message clears; intermittent, may require multiple attempts to shut vehicle off
Widespread across Sierra HD 2020+ fleet; NHTSA complaints show 11 electrical complaints for 2022 MY alone, many citing Shift-to-Park. Repeated service visits for the same symptom with a documented TSB builds the 'same defect' pattern under Song-Beverly.
Per GM TSB PIE0568A: diagnose park switch circuit; replace transmission shifter assembly if signal does not drop appropriately
Seat belt in front-row center position may not secure properly; belt hardware loose; potential for belt to detach in a collision
Two concurrent seat-belt recalls on the same model year cohort indicates systemic assembly-line quality failure. Clients whose vehicles were unrepaired at time of a collision may have heightened claims.
Recall 20V792: inspect and reassemble seat-belt brackets; Recall 20V811: replace incorrect bolts — both at no charge
Harsh or jerky gear changes; delayed shift into reverse; slipping between gears; check-engine or transmission warning light; limp mode activation; transmission overheating message
NHTSA complaint data shows transmission issues are the single largest complaint category across 2020-2023 MYs (28 of 72 complaints in 2020; 17 of 27 in 2023). Widespread part shortages (up to 3 months backorder in 2023) may support a presumption of nonconformity under Song-Beverly.
Reprogramming transmission control module per GM service bulletins; valve body or transmission assembly replacement when internal failure confirmed
open
Same water-intrusion short-circuit defect as 24V060; covers additional 2024 GMC Sierra HD units not included in the initial recall scope.
open
Electronic gate-release switch in power-unlatching tailgate may short circuit due to water intrusion, causing the tailgate to inadvertently unlatch while the vehicle is in Park.
open
Steering gear shaft contains a supplier manufacturing defect that may cause it to fracture and disconnect from the pitman (steering) arm.
open
Bolts attaching the BPMV assembly may not be properly torqued, allowing water to intrude between sub-assemblies. Water ingress can cause an electrical short circuit.
open
Incorrect-specification bolts may have been used at one or more fastening locations to secure the seat belts to the vehicle.
open
Seat-belt brackets may not be secured to the seat frame in the front-row center seating position.
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 (the 'lemon law') applies to new vehicles still under the manufacturer's original warranty. If GM or an authorized dealer has been unable to repair a defect — or the same defect — after a reasonable number of attempts, and that defect substantially impairs the vehicle's use, value, or safety, you may qualify for a full repurchase (refund of payments and down payment, minus a mileage offset) or a replacement vehicle of equal value. If GM was aware of the defect and chose not to repair it in good faith, California law allows a court to award up to two times the actual damages as a civil penalty.
A 'reasonable number of repair attempts' is not a fixed number but courts routinely find two or more attempts for a safety-related defect to be sufficient. For catastrophic safety defects — like a steering failure or fire risk — even one unresolved attempt may qualify.
This is general legal information only and is not legal advice. Whether your specific truck qualifies depends on the details of your situation. Contact a California lemon-law attorney to evaluate your repair history.
“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.
Dealers sometimes close a repair order with 'could not duplicate' or 'no fault found' — especially on intermittent issues like the 'Shift to Park' warning or tailgate that only pops open in wet conditions. This does not end your case. Here is what to do:
1. Document every occurrence before you go to the dealer. Photos or short phone videos showing the tailgate open while the truck is moving, or the 'Shift to Park' message on the DIC, are powerful evidence that cannot be dismissed.
2. Request a specific diagnosis tied to the recall or TSB. Recall 24V060 (tailgate switch) and TSB PIE0568A (Shift to Park) are published, dealer-accessible documents. Ask the service advisor to run diagnostics specifically referencing those documents and put that request in writing on the repair order.
3. Note the weather conditions. The tailgate switch defect is triggered by water intrusion — if you're having symptoms after rain or a car wash, say so on the repair order. That context makes 'can't duplicate' harder for the dealer to sustain.
4. Keep every repair order, even ones that say 'no fault found.' Under California's Song-Beverly Act, each dealer visit for a covered defect counts toward the repair attempt threshold — including visits where the dealer fails to diagnose the problem.
5. Ask for the repair order in writing before you leave the dealership. You are entitled to a copy each time. If the dealer won't provide one, note the date and take a photo of the service check-in.
6. Do not let recall repairs substitute for lemon-law repair attempts. A recall completion record is separate from a warranty repair attempt. Both matter, and both count in a lemon-law analysis.
The Sierra 2500 HD gas truck is a serious work vehicle, and the defects documented here are serious safety failures — not comfort complaints. A tailgate that opens at highway speed and ejects cargo, a steering shaft that can snap and leave you with no steering, or a fire risk that requires parking outside: these are conditions no owner should have to accept from a $60,000-plus pickup truck. The fact that GM needed two separate recall campaigns to address the tailgate issue — 24V060 in February 2024, then 24V894 nine months later for units the first recall missed — suggests the underlying problem was broader than initially acknowledged. If your truck has been in for these issues repeatedly and GM has not made it right, the law may be on your side.

Has your Sierra 2500 HD been back to the dealer more than once for a tailgate that opens by itself, a transmission that slips or fails, or a 'Shift to Park' warning that won't quit? If your truck is still under GM's factory warranty and these repairs haven't stuck, you may have a California lemon-law claim. A free case review takes minutes and costs nothing. Find out if GM owes you a replacement truck or a refund.
Yes. NHTSA issued recall 24V060 in February 2024 covering over 194,000 GMC Sierra 2500/3500 HD trucks built for model years 2020-2024 that were equipped with the optional power-unlatching tailgate (RPO QT5). Water can intrude into the tailgate and contact the electronic release switch, causing a short circuit that unlatches the tailgate without any input — including while the truck is moving. A second recall campaign, 24V894, was issued in November 2024 to capture 2024 model year trucks missed in the original filing. The remedy at the dealer is replacement of the exterior touchpad switch assembly at no charge. Check your VIN at NHTSA.gov to confirm whether your truck is included.
Yes, this is a documented and widespread problem across the 2020-2026 Sierra 2500/3500 HD fleet. General Motors issued Technical Service Bulletin PIE0568A to address it. The root cause is the park switch in the transmission shifter assembly failing to pull the body control module (BCM) signal low, so the BCM does not recognize that the truck is actually in Park. The result is the 'Shift to Park' message persisting on the Driver Information Center (DIC) even with the shifter in Park, and the truck refusing to power off normally. The dealer fix per the TSB is to inspect the park switch circuit and replace the shifter assembly if the signal is not dropping correctly. If you've had this repair performed more than once without lasting resolution, it may support a lemon-law claim for a recurring electrical defect.
It can, if the facts fit. Under California's Song-Beverly Act, a new vehicle that has a defect substantially impairing its use, value, or safety — and GM or an authorized dealer has been unable to repair it after a reasonable number of attempts during the warranty period — may qualify for a repurchase (refund) or a replacement. The Sierra 2500 HD gas truck has multiple confirmed safety recalls (tailgate, steering shaft fracture, BPMV fire risk) and a documented electrical defect (Shift to Park). If you have repair orders showing repeated dealer visits for any of these issues without a lasting fix, those records are the foundation of a lemon-law evaluation. A free case review with a California lemon-law attorney can tell you quickly whether your truck's history meets the threshold.
NHTSA recall 21V758 covers 2021-2022 model year GMC Sierra 2500/3500 HD trucks (and Chevrolet Silverado HD) where the electronic brake control module (EBCM) was replaced during the assembly process. In those vehicles, the bolts on the Brake Pressure Modulator Valve (BPMV) may not have been tightened to specification, leaving a gap that allows water to enter the BPMV. That water intrusion can cause an electrical short circuit serious enough to start an underhood fire. General Motors issued a 'park outside and away from structures' advisory to affected owners until the recall repair is completed. The remedy is dealer replacement of the BPMV assembly at no charge. If your truck's VIN is included and the repair has not been completed — or if the dealer attempted the repair but you've since noticed smoke or burning odors — that is a significant safety matter and may support a lemon-law claim.
No. A 'could not duplicate' or 'no fault found' repair order still counts as a repair attempt under California's Song-Beverly Act. The law measures whether the manufacturer had a reasonable opportunity to fix the defect — not whether they successfully fixed it. In fact, a pattern of 'no fault found' closures combined with a recurring symptom can strengthen a claim by showing the defect is persistent and the manufacturer's response has been inadequate. Document every occurrence with photos, notes of dates and conditions, and keep every repair order (including the 'no fault found' ones). NHTSA complaint data for the 2020-2023 Sierra 2500 HD shows transmission problems — including harsh shifts, limp mode, and highway lockups — are the single largest owner-reported complaint category, which supports the argument that the defect is real and widespread even when individual dealers fail to diagnose it.
Yes. NHTSA recall 23V549 (issued August 2023) covers 2024 model year GMC Sierra 2500/3500 HD trucks where a supplier manufacturing defect may cause the steering gear shaft to fracture and disconnect from the pitman arm. If this happens, the driver loses all steering control — the vehicle cannot be steered. Approximately 1,888 GMC Sierra HD trucks were identified in this recall. The remedy is dealer inspection and replacement of the steering gear assembly at no charge. Complete loss of steering is one of the most catastrophic safety defects a vehicle can have; even a single unresolved repair attempt for a defect of this severity may be sufficient to support a California lemon-law claim.
