On the 2022-2024 Cadillac CT4 2.7L Turbo V6, cT4-V Blackwing models with the 2.7L twin-turbo V6 (L3B) can develop a squeaking or squelching noise during acceleration, particularly once the engine is warm. The noise is often traced to turbocharger-related components including wastegate actuators, boost pipes, or turbo bearings. Some cases have required turbo replacement under warranty. The issue varies in severity from cosmetic noise to indicating actual component wear.
Have dealer diagnose the specific source of the noise. In many cases, tightening boost pipe clamps or replacing wastegate actuator resolves the issue. If turbo bearings are worn, warranty replacement of the turbocharger assembly is needed. Document the noise with video for the dealer visit.

On the 2022-2024 Cadillac CT4, some CT4-V Blackwing models with the 10-speed automatic transmission experience intermittent stalling and rough idle in stop-and-go traffic conditions. The engine may die at standstill and require restart. Reports indicate this occurring within the first 1,000 miles on new vehicles, suggesting a calibration issue rather than mechanical failure. GM has released preliminary engineering bulletins (PIE0744) for the 10-speed automatic in Blackwing models.
Have dealer check for latest ECM and TCM calibration updates. GM preliminary bulletin PIE0744 addresses idle and stall concerns on A10 Blackwing models. A TCM reflash typically resolves the stalling. If persistent, the throttle body and idle air control may need cleaning or replacement.

On the 2020-2025 Cadillac CT4, the CT4 base model uses the 2.0T LSY engine which shares the valve cover/PCV failure and turbo coolant line concerns found in the XT4. The PCV system integrated into the valve cover can fail between 40,000-80,000 miles, causing oil consumption, vacuum leaks, and rough idle. Turbo coolant line connections can develop slow leaks. The CT4-V uses a 2.7T engine (L3B) with different issues. The CT4-V Blackwing uses the 3.6L Twin-Turbo (LF4) which is bespoke and generally reliable.
Replace valve cover assembly for PCV failure (GM updated design available). Inspect and replace turbo coolant lines if leaking. 5,000-mile oil change intervals with full synthetic are important for turbo longevity.

On the 2022-2024 Cadillac CT4, cT4-V and CT5-V Blackwing owners have reported various build quality concerns including excessive paint orange peel, panel gap inconsistencies, interior trim rattles and squeaks, and loose exterior trim pieces.

Issues are more commonly reported on early 2022 production vehicles.
Document all issues thoroughly with photos during the initial delivery inspection. Report paint quality issues within 30 days of purchase for potential warranty paint correction. Interior rattles can often be resolved with dealer adjustments to trim clips and sound deadening. Check Cadillac V-Net forums for specific rattle locations and DIY fixes.
