The transmission (power train) transmits engine torque to the drive wheels, multiplying torque at low speeds and allowing efficient cruising at highway speeds. Modern designs include torque-converter automatics, dual-clutch units, continuously variable transmissions (CVTs), and electric-vehicle reduction gearboxes. NHTSA reports describe harsh shifts, slipping under load, complete loss of forward or reverse, premature CVT belt failures, valve-body solenoid faults, and on dual-clutch units, shudder during low-speed engagement. A failed transmission can leave a vehicle stranded mid-traffic, and unintended downshifts or sudden engagement can disrupt vehicle control. Replacement is typically among the most expensive non-engine repairs.
Burnt fluid smell, delayed engagement when shifting from park, harsh shifts or slips, and any warning related to transmission temperature should be diagnosed before continued driving compounds damage.
With 750 gmc transmission complaints reported across 6 models spanning 2015–2026, this combination falls into a high signal band. In practice, that means the volume is at a level that frequently corresponds to either an active recall, an open investigation, or a Technical Service Bulletin issued to dealerships — owners should check whether their VIN is covered by any active campaign. Complaint volume is not the only thing that matters — severity (whether the defect caused crashes, fires, or injuries) and consistency (whether multiple owners describe the same failure mode) are equally important when assessing real-world risk.
This breakdown shows how Gmc Transmission complaints are distributed across model years. A concentration in a particular year usually signals a generation-specific defect that may have been corrected in subsequent model years.
| Model Year | Vehicles | Complaints | Distribution |

| 2026 | 2 | 2 | |
| 2025 | 1 | 1 | |
| 2024 | 3 | 17 | |
| 2023 | 3 | 31 | |
| 2022 | 4 | 20 | |
| 2021 | 5 | 43 | |
| 2020 | 5 | 35 | |
| 2019 | 4 | 125 | |

The following Gmc models account for the bulk of transmission complaints in our database. Vehicles near the top of the list have either widely-reported defects or simply higher production volumes — the per-model trim and year pages provide context to distinguish the two.
If your vehicle is exhibiting gmc transmission issues that match the patterns described in NHTSA complaints, take these steps in order. First, check your VIN for active recalls using NHTSA's free recall lookup tool — recall remedies are repaired at no cost to the owner regardless of warranty status. Second, document the failure with dated photos or video, and keep copies of any service records, parts replacements, or dealer communications related to the issue. Third, file a complaint with NHTSA at nhtsa.gov/recalls — every complaint contributes to the pattern recognition that triggers investigations and, ultimately, recalls. The complaint should describe what happened, when, the vehicle's mileage at the time, and whether anyone was injured. Fourth, if the issue presents an immediate safety hazard (loss of braking, steering, throttle control, fire, or unintended airbag deployment), discontinue driving and have the vehicle towed to a qualified repair facility rather than risking a crash to reach a dealer.
The data on this page is drawn from three distinct NHTSA sources that owners frequently confuse. Complaints are reports submitted by individual vehicle owners describing a problem they experienced — they are unverified narratives, but in aggregate they reveal patterns. Recalls are formal manufacturer-initiated campaigns to repair a confirmed safety defect on a specified set of VINs; the manufacturer pays for the repair and is required to notify affected owners by mail. Investigations are NHTSA-led inquiries that often start when complaint volume crosses a threshold for a particular component or model — they may conclude with a manufacturer-issued recall, a finding of no defect, or remain open while data accumulates. A high complaint count without a corresponding recall does not mean the issue is unimportant; it sometimes means an investigation is ongoing or that NHTSA has not yet acted. Conversely, a small recall on a low-complaint model means the defect is severe enough that the manufacturer chose to remediate proactively.
This page aggregates gmc transmission safety records published by the U.S. National Highway Traffic Safety Administration (NHTSA). Records are matched to make, model, and year using NHTSA's classifications, and complaint counts are deduplicated by ODI number. The dataset includes consumer complaints, manufacturer-issued recalls, Technical Service Bulletins, and crash investigations. Most recent record on this page was updated on 2026-03-29. Counts on this page reflect what is currently in our database; we do not include records flagged as duplicate, withdrawn, or outside the model-year window.
NHTSA's database currently shows 750 gmc transmission complaints across 6 distinct models spanning 2015–2026. Complaint counts grow continuously as new owner reports are filed and processed.
The Acadia, Yukon, Canyon lead the list, with the top model accounting for 404 reported transmission complaints. The complete model breakdown is available in the table on this page.
Among the records on this page, the 2017 model year accounts for the highest transmission complaint volume (207 reports). A concentration in a single year often indicates a generation-specific defect; concentrations across consecutive years can suggest an ongoing supplier or design issue.
Recall status varies by VIN. Even when complaint volumes are high, recalls are issued per-defect, not per-component, so some gmc transmission complaints lead to recalls while others remain unaddressed. Check your specific VIN against NHTSA's recall lookup or browse the recall pages linked from each vehicle profile to see which campaigns apply.
Complaints are unverified owner reports; recalls are formal manufacturer campaigns to repair confirmed defects on specified VINs at no cost to the owner. Complaints often come first and, when patterns emerge, can prompt investigations that lead to recalls. A high complaint count on a vehicle without a recall does not mean the issue is benign — it sometimes means investigation or remedy is still in progress.
It depends on (1) whether the issue is covered by an active recall and the recall has been performed, (2) the severity of the failure modes reported, and (3) whether the specific VIN has a documented service history showing the relevant repairs. A used-vehicle inspection by a qualified mechanic, plus a VIN check against NHTSA's recall database, are the practical minimum steps before purchase.
Submit safety complaints directly to NHTSA at nhtsa.gov/recalls — there is no fee, and you do not need to be the original owner. Include the VIN, model year, mileage at time of incident, a description of what happened, and whether anyone was injured. Each complaint contributes to the pattern recognition NHTSA uses to decide whether to open an investigation.
