collision, the passenger airbag will not deploy, creating an immediate and severe safety hazard for any occupant in that seat. This error message appeared while in the dealerships possession for an unrelated issue. The dealership service technician confirmed the faulty module and stated they are not able to complete the repair due to discontinued parts. see attached. General motors (GM) has officially discontinued the vehicle-specific replacement parts (Part #23504892 & #23504893) required to fix this defect. Dealerships are turning owners away because the parts are entirely unavailable nationwide, and standard components from higher-volume GM models are incompatible with the low-production ELR seat configuration. This leaves owners with a permanently disabled safety system and no manufacturer-supported path to repair a critical restraint component. Because this is a widespread, identical failure among 2014 ELR vehicles that results in total airbag deactivation, a federal safety investigation and recall are required to force the manufacturer to produce a batch of functional safety components.
The passenger occupancy sensor has failed on my 2016 ELR after 14k miles. The part is no longer available (23504893). I've inquired with General Motors and they said they could not help me. This seems to be a 1year only part used only on the Cadillac ELR. I believe this is an integral part of the Air Bag safety system in my vehicle and that the passenger seat is no longer safe for passengers.
Initial repair of the vehicle was initiated on 9/12/25 due to a dashboard warning message indicating an air bag system fault. The Cadillac dealership was unable to complete the repair during the initial service visit. The vehicle was returned to the dealership in October 2025 and has remained there since that time. The dealership has confirmed that the Air Bag Front Passenger Sensor Kit (Part #23504893) failed following repair of the driver side air bag module. As a result of this failure, the passenger side air...

bag sensor does not function as designed. This condition creates a significant safety risk, as any passenger seated in the front passenger seat would be at increased risk of serious injury or death in the event of a collision. The issue has been inspected and confirmed by the authorized Cadillac dealership. I have been advised that this part is no longer manufactured by Cadillac and is unavailable for replacement, rending the vehicle unsafe to operate. I am the original and sole owner of the vehicle; whish has fewer than 50,000 miles. Based on the vehicle's age, mileage, and maintenance history, I reasonably expected many additional years of safe operation. Due to the confirmed air bag system failure and lack of available replacement parts, the vehicle cannot be safely driven and represents a major safety defect.
Vehicle is producing a "Service Airbag" warning message and red airbag light on the instrument cluster at each start. The problem code 'U0170' is found which correlates to 'Lost Communication With Passenger Presence Module'. The dealer advised that the part is discontinued and no longer available. The needed Part Number is: 23504892 which is a single year, single model only part. I checked with numerous aftermarket sources as well as salvage yards for an alternative to the GM part, but no luck. It appears the part...

does not exist in the marketplace. The dealership, and Cadillac Customer Service, were unable to provide a path forward. I am left no alternative but to operate the vehicle without the passenger side airbag and any other airbags that may be tied to the inability of the car to detect the presence of a passenger in the seat, as well as an annoying error and light every time I start the car.
An 'amber' airbag malfunction light has illuminated on the instrument panel. The airbag light has since turned 'red'. It is 'red' to this date. The manufacturers guide advises to take the vehicle to the dealer. The authorized Cadillac dealer in our town troubleshot the problem to code 'U0170', 'Lost Communication With Passenger Presence Module'. The dealer advised that the part is no longer available. The needed Part Number is: 23504893. I checked with numerous aftermarket sources for an alternative to the GM...

part, but no luck. It appears the part does not exist in the marketplace. The dealership, and Cadillac Customer Service, were unable to provide a path forward. To assure my families' safety, it appears I have no alternative but to scrap this otherwise very fine eight year old Cadillac. I have documentation from my local Cadillac Dealership, as well as my communication with Cadillac Customer Service, and can provide it if needed.
The vehicle lost all power while driving; this has occurred four times between August 2024 and November 2024. Without warning, the vehicle loses power, including brakes, steering, lights, warning flashers, doors, etc., all power goes away. This has occurred three times during the day and once at night, creating a hazard for myself and other drivers. The vehicle has been towed to the dealership three times, where it restarts. There are no codes to be found and GM is uncertain of what to do.
