When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2024 Cadillac CT4
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.

Lights And Instruments
Issue: On certain vehicles, a software problem could cause the lower beam headlamps not to turn on as it becomes dark outside if the multi-function switch is in the "OFF" or "PARKING LAMP" position. This could also cause the daytime running lamps (DRLs) to turn off when the vehicle is moving. As a result, the vehicles may not meet certain requirements of Canadian regulations. Safety Risk: Headlamps and/or DRLs that don't turn on could reduce visibility, make the vehicle less visible to others and increase the risk of a crash. Corrective Actions: General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the body control module (BCM)software.

VISIBILITY/WIPER
In November 2023 I purchased this vehicle. The dealership was made aware of the ripples within a few days of driving the vehicle. The windshield was defective and had to be replaced. The staff at the dealership did see the ripples on the windshield and agreed to replace the windshield. On December 14, 2023, the dealership replaced the original windshield even though they had the windshield since November 22, 2023. Within a few days of driving the vehicle, I noticed it also has ripples on the 2nd windshield. I have been to the dealership two times, and no one can see ripples. I have taken the vehicle to an automotive glass company who confirmed the ripples in the windshield. On February 5, 2024, I took the vehicle to a different dealership. The appointment was scheduled by a General Motors representative. The staff at the second dealership cannot see anything and took pictures to send to General Motors. The ripples in the windshield are distracting when driving in the daytime and nighttime.
