2016 Cadillac ELR Owner Complaints

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.

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.
