The 2017 Silverado received a mid-cycle refresh but kept the same EcoTec3 engines with AFM and the 8L90 8-speed. AFM lifter failures and 8L90 shudder continue to be the dominant complaints. The truck is more refined but the drivetrain risks remain.
Continued AFM lifter risk and 8L90 shudder. Refresh updated styling and tech but did not address core drivetrain issues. TSB 18-NA-355 covers transmission shudder; class actions ongoing.
Same as earlier years. Preventive delete is the most reliable path.

Avoid unless prepared for AFM and 8L90 work. Refresh added refinement but core drivetrain risks unchanged.
No - the 2017 inherits all the 4th-gen problems. Refresh year refinements but the 5.3L L83 with AFM and 8L90 with shudder are still in use.
Expect $800-1300/year in routine maintenance. Plan for AFM delete and 8L90 service. Lifetime non-routine cost: $6,000-12,000 to 200K miles.

If your 2017 Silverado is throwing a check engine light, these are the codes most often associated with the problems above. Click any code for full diagnosis steps and typical repair costs.
Slightly - refresh tech and refinement. But AFM and 8L90 shudder remain. Drivetrain risk is the same.
Disable AFM with a tune and install non-AFM lifters proactively. $1500-3000 typically.
Mostly via TSB 18-NA-355 fluid swap to Mobil 1 LV ATF HP. Verify completion on any used 8L90 truck.
Highly variable. With proactive AFM delete and 8L90 fluid service, 200K+ is realistic.
For power, yes. For reliability, no - both 5.3L and 6.2L have the same AFM lifter risk.
