Quality
When building cars, brands can’t afford small, inconvenient, careless mistakes. It’s unfortunate that in a world where almost anything can be done efficiently and properly, careless mistakes can still arise on the production end. These small mistakes hurt the brand’s overall image when it comes to quality.
GM has had a strange number of small quality control issues across its brands lately. The latest one could have easily been avoided, and it involves an important part, too.

Loose Filters
GM Authority just released a report saying some Chevrolet Silverado 1500s, Colorados, and Blazers were shipped from the production facility with loose oil filters. The cause? Apparently, they just weren’t tightened enough (sigh), which could cause future oil leaks for owners. In more detail, the service bulletin issued by GM says the affected cars may have shipped with an improperly torqued oil filter, which means it wasn’t tightened properly during production.
The service bulletin was released in August but isn’t as specific as one would think. The report only says “certain models” of the 2026 Blazer, 2026-2027 Colorado, and 2026 Silverado 1500 are affected. It also doesn’t say how many cars between those production dates are affected by the loose oil filter. Instead, the bulletin says authorized dealerships must first check the vehicle’s VIN to determine whether it’s part of the recall. Strangely, the bulletin also doesn’t specify which engine or production plant these affected models came from.

Simple Fix
Since the issue itself isn’t what you’d call a “biggie,” the fix is also straightforward. All the dealership needs to do is have a technician inspect the oil filter; if it’s loose, they’ll tighten it to the required specification. If oil has already seeped out because of the loose filter, the technician will tighten it and top up the oil back to the required level.
