It all comes back to how cars are built now; with more models and a faster pace, quality control issues slip through and ultimately affect the ownership experience.In some cases, the issues are big, but the more annoying ones are small and could have been avoided or caught if production and inspection had been more thorough. GM's already dealing with one loose oil filter issue, and it seems more is coming from the auto giant under the Cadillac brand.CadillacLeaky Oil FilterA report by GM Authority points to another case of a car being assembled and shipped with a loose oil filter. This time, the new bulletin is identified as Service Update N262568830, which states that some Cadillac CT5 sedans were shipped with an oil filter that wasn't tightened to the proper production specification. As we all know, a loose oil filter can cause oil to leak, which is very bad for an engine.AdvertisementAdvertisementWhat's interesting is that the report says the GM service bulletin states the issue affects only some models of the 2026 Cadillac CT5, meaning not all variants and powertrain options are part of the service advisory. However, the bulletin doesn't go into detail on which variants are affected or how many.2026 Cadillac CT5-V BlackwingCars & BidsDon't PanicGM's belief that this issue isn't so important comes from the fact that they're telling CT5 owners there's no need to immediately schedule a service appointment to check whether your car is affected. Instead, the brand says it can be done during the car's scheduled maintenance interval. Of course, if you want to be sure, you can follow your own gut instincts and have your car checked anyway.The fix is thankfully easy for affected cars, as a service technician will check whether your oil filter is loose. If it is, the technician will simply tighten it and top up your car's oil if needed.CadillacThis story was originally published by Autoblog on Sep 15, 2026, where it first appeared in the News section.
