Not safety, but GM recalled 2021Trailblazers to replace Evap Purge Pumps on vehicles showing check engine light resulting in bad purge pump diagnosis. Why only Trailblazers" I recently had to replace one on my 2021Envision at 37,588 miles after my check engine light came on. Fortunately I bought the extended insurance when I purchased my new vehicle and only paid the $100 deductible. Otherwise it would have cost me $404. If they knew of problems for that year, why not send out letters to other owners of GM vehicles" Thank you.
