GM has issued a new customer satisfaction program, number N222395370, for certain units of the 2022 Cadillac CT4 and 2023 Cadillac CT4 built with an engine wire harness that may come in contact with other engine parts.
The engine wire harness of the affected Cadillac CT4 units may contact the vehicle’s brake line, brake line coupler, thermostat housing, or some combination of these components according to the customer satisfaction program.
GM instructs dealerships to check the Investigate Vehicle History screen for a potentially affected Cadillac CT4, using the GM Global Warranty Management system. Affected vehicles are marked “Open” in the system, and once verified the dealer service personnel can begin inspection and repairs.
GM suggests carrying out an inspection before ordering parts for the fix of the Cadillac CT4. The bulletin notes some vehicles may need additional parts, and furthermore states there is initial limited parts availability for the repair. GM may place a quantity limit on the number of parts a particular dealership can order for the fix.
The repair itself consists of installing an anti-abrasion sleeve, including a Brake Pipe Assembly and a Brake Pipe Protective Sleeve, to prevent further abrasion. Additionally, the engine wire harness wire fastener should be replaced with a zip tie, applied in such a way as to secure the harness away from the brake line.
The fix covered by this customer satisfaction program is available through September 30th, 2025.

As a reminder, the Cadillac CT4 rides on the GM Alpha 2 platform. Standard motivation is supplied on all three trim levels by the turbocharged 2.0L I4 LSY gasoline engine developing 237 horsepower and 258 pound-feet of torque. The Premium Luxury trim level offers the turbocharged 2.7L I4 L3B, rated at 310 horsepower and 350 pound-feet of torque, as an option.
Cog swaps for the LSY engine are provided by the GM eight-speed automatic transmission, while the L3B engine connects to the GM 10-speed automatic transmission. All trims are available in both rear-wheel drive and optional all-wheel drive configurations.
Production of the Cadillac CT4 takes place at the GM Lansing Grand River plant in Michigan.
