POWER TRAINJul 2026

On July 22, 2025, at 20,245 miles, I brought my 2019 Cadillac CT6-V to an authorized dealer while still under factory warranty, reporting hard shifting during both acceleration and deceleration — the exact symptom described in GM Special Coverage Bulletin N242480631, which addresses a defective transmission control valve subject to premature wear (P0747 diagnostic condition). The dealer was unable to diagnose or repair the issue at that visit and returned the vehicle to me without resolving the defect. The same condition recurred. I brought the vehicle back to the dealer (Crestview Cadillac, Rochester Hills, MI) on May 26, 2026. The vehicle remained at the dealership for over three weeks before any loaner vehicle was offered. Replacement parts were reported as received on July 3, 2026, and again on July 17, 2026, and as of this filing the vehicle has still not been returned to me — over two months out of service. The repair estimate is approximately $12,000, covering the transmission control valve, a power transfer case, and a high-pressure oil pump. GM Special Coverage Bulletin N242480631 states that the control valve body replacement is covered at no charge for vehicles that return with a P0747 condition after the TCM software update, for 15 years or 150,000 miles from the in-service date, regardless of ownership. My vehicle meets these conditions. Despite this, GM's case team has offered only a $4,500 "goodwill" credit plus reward points toward the total repair, characterizing this as a discretionary gesture outside of warranty, and has stated this is their final position. I am filing this complaint because: (1) the original recall/coverage remedy did not resolve the underlying defect when I first brought the vehicle in under warranty, resulting in continued use of a vehicle with an unrepaired safety-related transmission defect until the condition worsened; (2) GM's dealer network has taken an extended and, in my view, excessive amount of time to complete.

POWER TRAINMay 2025

On several separate occasions, my Cadillac CT 6 which has been under recall for months by General Motors does not have an adequate repair for the repair shops authorized by the manufacturer, namely GM franchised Cadillac dealer repair shops and hence I am unable to have my vehicle repaired because the franchised GM dealers inform me that due to the recall and General Motor’s refusal or inability to provide specific reason for the transmission failure and the automobile not being able to shift into park when it is on an incline has rolled backwards when my door was open. I was attempting to get out of the car when it began rolling backward I was able to step on the brake: I would’ve been severely crippled or killed. Further to the preceding I have contacted CEO Mary Barra pertaining to the preceding and an executive inquiry person named “Thomas” informed me he will call me back with a resolution and has not done so. I do not have any other vehicle. I am a [XXX]. I have [XXX] and I cannot utilize my car safely and General Motors: Refuses to give me a replacement car, refuses to provide the franchisee with a written cause for the failures and solution for their mechanics to fix the vehicle, and therefore I respectfully request that the manufacturer be mandated to buy this vehicle back for its full purchase price: that they sold it to me defective knowing that there was a defect in this transmission and that they previously have covered up engine failure when the CEO was Mary Barra, the CEO again is Mary Barra, and she authorized General Motors to pay to the federal government $900 million because General motors “covered up” the engine defect in 2015 and approximately 3 to 4 years later in 2018–2019 CEO Mary Barra & GMC commit recidivism and in 2025 place me in harms way. I emailed Mary Barra directly as well as called her office and she refuses to inform me what the cause of this failure of the transmission and powertrain is.

POWER TRAINMar 2025

I am experiencing recurring transmission and drivability issues with my 2016 Cadillac CT6. 1.Rough Shifting: When shifting from park to reverse, the transmission shifts roughly, causing a noticeable jolt throughout the vehicle. 2.Fluid Leakage: I have observed fluid leaking from underneath the car when parked in my driveway. However, the leak is inconsistent—it disappears for a few days after rain or washing my driveway but then reappears under similar conditions. 3.Delayed Shifting: When accelerating from a stoplight, there is a delay before the transmission engages, causing hesitation before the car moves forward. 4.Automatic Start-Stop Issue: The vehicle has an automatic engine shut-off feature that activates when stopping at a light. When I take my foot off the brake, the engine restarts abruptly, causing a harsh jerk that shakes the entire car. This makes it feel like the transmission or another component is not engaging smoothly. 5.Check Engine Light Issue: The check engine light came on for a day, but before I could take it to a repair facility, it turned off on its own. Because of this, I was unable to retrieve any diagnostic codes. I am concerned these issues indicate a faulty transmission system or related defect that may worsen over time. I request an investigation into whether this is a common defect in the 2016 Cadillac CT6 and if any recalls or manufacturer repairs are available.

The basics

How to read this data

Complaints, recalls, investigations — here’s what each number actually tells you about a used Cadillac CT6, in plain English.

01

What is an NHTSA Complaint?

An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Cadillac CT6 has 76 complaints on record across 5 model years.

02

What is a Safety Recall?

A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Cadillac CT6 has 13 recall campaigns in the NHTSA database.

03

What Are Crash Complaints?

Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 5 of the Cadillac CT6's 76 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.

04

How Is the Reliability Verdict Calculated?

The reliability verdict (Average) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.

05

Why Do Newer Years Have Fewer Complaints?

Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.

06

Fleet Data vs. Individual VIN

Everything on this page reflects aggregated data across all Cadillac CT6 vehicles on the road — not any specific car. Two Cadillac CT6 vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.

07

What Are NHTSA Investigations?

When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Cadillac CT6 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
