Independent model research guide
Build the Cadillac CT4 repair record before drawing conclusions.
The goal of this model page is practical: confirm vehicle identity, preserve the repair chronology, connect recurring symptoms, and identify the records needed for a fact-specific California lemon law review.
Warranty limits may differ by component and may be affected by the in-service date and mileage. Start with the booklet and written coverage supplied for this vehicle.
Model-aware documentation
Issue categories to document for a Cadillac CT4.
These are investigation prompts, not statements that the model has each problem. Select only the categories that match the actual vehicle and repair orders.
Engine, power delivery, or stalling
Record the operating conditions, warning messages, speed, temperature, and whether the concern returned after repair.
Transmission, shifting, or drivability
Note hesitation, harsh engagement, slipping, vibration, or loss of response and the exact conditions in which it occurs.
Electrical power and recurring warnings
Save photographs of warning lights, no-start events, battery replacements, diagnostic codes, and modules tested or replaced.
Software, displays, cameras, and connectivity
Identify update or calibration numbers, failed features, reset attempts, and whether the same symptom returned after programming.
Driver-assistance and safety-system alerts
Document unavailable features, false alerts, braking or steering interventions, sensor conditions, and dealer test results.

Cadillac CT4: NHTSA records by model year
Find your model year, distinguish a safety recall from a service bulletin or owner report, and compare the records with your vehicle’s VIN, equipment, and repair history.
Indexed source review: September 24, 2026 · Model-year window: 2021–2026
Model year 2021

Agency record · Closed
Air Bag Malfunction
The 2021 CT4 is listed in this investigation record. An investigation concerns an agency inquiry; its opening is not a final defect determination, and closure alone is not a finding that every vehicle is safe or repaired.
Agency summary excerpt: “On April 9, 2021, the Office of Defects Investigations (ODI) opened PE21-010 to investigate instances of air bag malfunction indicator light (MIL) illumination and potential for frontal air bag non-deployment in several vehicles manufactured by General Motors (GM). The vehicles …”
Agency disposition and source
In view of the low rate, and the nature of early-life failure, the high detectability of failures, and low potential hazard to drivers, this Preliminary Evaluation (PE) is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.Review the ODI reports cited above at nhtsa.gov under the following identification numbers: 11537927, 11528888, 11525020, 11521401, 11506057, 11493107, 11486767, 11441525, 11433146, 11425658, 11423440, 11385267, 11376429, 11373466, 11366995.

Exterior Lighting: Lighting Control Module: Software
The campaign addresses crash risk involving the listed component. Its applicability is limited to the affected vehicles and equipment described by General Motors, LLC.
Reported condition: “The daytime running lights (DRLs) may not deactivate when the headlights are on. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and …”
Scope, remedy, and official notice
Applicability in the source: General Motors, LLC (GM) is recalling certain 2020-2023 Cadillac CT4 and CT5; 2021-2023 Buick Envision; and 2022-2023 Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles.

The indexed entry does not supply the principal star-rating values shown in this review. An equipment listing is not a crash-test rating.
These results belong to the stated model year and configuration. Do not transfer them to a different body style, drivetrain, or trim. A rating does not resolve whether a particular vehicle has an open recall or recurring repair condition.

Model year 2024
2024 Cadillac CT4
No safety-recall campaign was supplied for this model year in the indexed search. That is not a current VIN clearance. Owner-report entries are most numerous in engine and cooling (3) and visibility, cameras, and driver assistance (2). 389 manufacturer communications are organized separately below so workshop instructions are not mistaken for confirmed owner failures. Start with any applicable safety instructions, then match the service documents and reported conditions to the actual repair orders.

2026 Cadillac CT4
No safety-recall campaign was supplied for this model year in the indexed search. That is not a current VIN clearance. Owner-report entries are most numerous in visibility, cameras, and driver assistance (1) and electrical systems and software (1). 83 manufacturer communications are organized separately below so workshop instructions are not mistaken for confirmed owner failures. Start with any applicable safety instructions, then match the service documents and reported conditions to the actual repair orders.

Repair chronology
Turn every CT4 visit into a usable timeline.
Place the final repair orders in date and mileage order. Compare the customer complaint, technician findings, correction, and post-repair result instead of relying only on a dealer summary or online discussion.
Do not combine multiple visits into one estimate. Open and close dates, mileage, parts delays, diagnostic time, and the date the vehicle was actually available can answer different questions.

California legal framework
The statute applies to the evidence—not the badge.
California Civil Code section 1793.2 addresses warranty repair obligations and, in specified circumstances, replacement or restitution after a reasonable number of repair attempts. Section 1793.22 defines the Tanner presumption and “nonconformity.” Those provisions require a fact-specific analysis.
Applicable warranty
Identify the written coverage in effect when the concern was presented.
Repair opportunity
Show when and how the manufacturer or authorized facility received the vehicle.
Substantial impairment
Document the effect on use, value, or safety rather than relying on labels.
Remedy analysis
Compare restitution, replacement, negotiated resolutions, offsets, and supporting damages.
Warranty and escalation record
Separate the Cadillac CT4 warranty from other contracts.
A manufacturer warranty, certified coverage, dealer promise, and separately purchased service contract may have different obligors and terms. Preserve each document instead of calling all coverage an “extended warranty.”
Save every Cadillac dealer message, repair authorization, parts-delay explanation, manufacturer case number, and written response. A phone call may matter, but a dated email, text, or letter usually makes the sequence easier to prove.
Primary and practical sources
Verify the law, vehicle, and warranty separately.

Clear answers
Cadillac CT4 lemon law questions
Can a Cadillac CT4 qualify under California lemon law?
It may, but the model name alone does not decide eligibility. A review should match the exact vehicle to an applicable written warranty and examine the repair opportunities, recurring nonconformity, mileage, downtime, and effect on use, value, or safety.
How many CT4 repair attempts are required?
There is no universal count that decides every case. California’s Tanner presumption describes specific circumstances, but claims can require a broader analysis of whether the manufacturer had a reasonable opportunity to repair the warranty problem.
Does a recall or service campaign prove that my CT4 is a lemon?
No. Recall, campaign, complaint, or bulletin information may provide context, but it does not prove the condition exists in this vehicle or establish a lemon law claim. Use VIN-specific information and the actual repair record.
What Cadillac CT4 records should I save?
Keep the purchase or lease agreement, warranty booklet, every final repair order, current registration and payoff information, photographs or videos, towing and rental records, and dealer or manufacturer messages and case numbers.
Can a used or leased CT4 qualify?
Possibly. The answer depends on the transaction, vehicle history, warranty that applied, timing of the repair visits, and other facts. A used or leased vehicle should be evaluated from its own documents.
What remedies may be available for a qualifying Cadillac CT4?
Depending on the facts and current law, possible outcomes can include restitution or repurchase, replacement, a negotiated cash resolution, warranty relief, incidental damages, or other remedies. No particular outcome is guaranteed.
