There are 2 owner-reported air bags & restraints complaints for the 2017 Cadillac CTSin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The airbag warning light appeared 45 days ago. I immediately took my 2017 Cadillac to the dealer (Sewell Cadillac of Houston). The vehicle is covered under a Sewell Extended warranty until 2028. The dealer performed troubleshooting and determined that the passenger seat sensors/module (part # 84567224 ) was defective. The Inspector for the Sewell Extended warranty confirmed that the replacement was covered by the warranty. The dealer advised after 30 days (completing other services- Brakes/rotors/front tires/spark plugs & wires etc) that the part # was “Back-ordered” and Sewell did not know when the part would be available, if ever. The consequence explained that the passenger seat which contains GM Part # 84567224 should not be used as the airbag may not inflate. Now the dealer wants their “loaner car” back and for me to pick up my “unrepaired Safety defective seat in my car”. Today’s date: December 20, 2025. The car was purchased new 11/2016 from the same Sewell Cadillac dealer. I would expect that General Motors be compelled to supply critical safety related equipment (part # 84567224) for a 8 year old car.
Passenger sensing device for the passenger seat is failing intermittently. Service airbag light is coming on periodically, and, when it does, the passenger "Airbag ON" light fails to illuminate even if a passenger over 100 lbs is in the seat. This is a long recurring issue with all GM cars where the sensing pad goes bad.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
