Common problems reported by 2024 Cadillac Ct4 owners, with recommended fixes and estimated repair costs.
Daytime Running Lights Fail to Deactivate
The DRLs may not deactivate when the headlights are on, affecting 2020-2023 CT4 models. This creates excessive glare for oncoming traffic and violates federal motor vehicle safety standards. The issue is caused by a body control module software bug.
NHTSA recall for BCM software update. Dealers update the body control module software, or the fix may be applied via OTA update. The repair is free of charge.
Est. Cost: $0 (recall repair)Roof Rail Side-Curtain Air Bag Installation Error
The roof rail side-curtain air bags may not have been installed correctly at the factory. Incorrectly mounted air bags can deploy improperly in a crash, potentially reducing their effectiveness at protecting occupants from head injuries in side impacts and rollovers.
NHTSA recall for 2020-2022 CT4 and CT5. Dealers inspect both side roof rail air bags and reinstall them correctly as necessary. Free of charge.
Est. Cost: $0 (recall repair)Power Steering Intermittent Failure
The NHTSA has received complaints about intermittent power steering failures at an average of only 2,250 miles. The electric power steering can cut out suddenly, requiring significant physical effort to steer. This is particularly dangerous at highway speeds or during evasive maneuvers. The issue may be accompanied by a steering warning light.
Dealer diagnoses the electric power steering system, including the motor, torque sensor, and wiring harness. Software update to the steering control module. Replacement of the electric power steering motor or steering gear assembly if the hardware is faulty.
Est. Cost: $400 - $2,20010-Speed Transmission Harsh Shifting
The 10-speed automatic transmission can exhibit harsh or jerky shifts, particularly between 2nd and 3rd gear and during deceleration downshifts. Some owners describe the shifts as jarring enough to move occupants forward in their seats. The issue is most noticeable during city driving with frequent speed changes.
TCM software update for improved shift calibration. Transmission adaptive learning reset. Transmission fluid service with the latest GM-specified fluid. In cases of persistent harsh shifting with wheel lockup risk, the 10-speed transmission recall software may apply.
Est. Cost: $0 (software update) - $3,000 (valve body replacement)Infotainment and CUE System Issues
The Cadillac User Experience (CUE) system may freeze, respond slowly to inputs, or fail to connect to smartphones via wireless Apple CarPlay or Android Auto. The touchscreen may become unresponsive in certain areas. Some owners also report the audio system cutting out or switching sources without input.
System software update at the dealer. Hard reboot by holding the power/volume knob. USB port and cable inspection for wired connectivity issues. In persistent cases, the infotainment control module or touchscreen assembly may need replacement.
Est. Cost: $0 (software update) - $1,500 (module/screen replacement)
