Recall work is free at a franchised dealer regardless of the vehicle's age, mileage, or how many owners it has had. Check your VIN against the NHTSA database to see what is still outstanding on your specific vehicle, a recall listed here may already have been performed.

AFM lifter failure (5.3L L83, also 6.2L)

major

The Gen V engines carried AFM forward and so did lifter failures: a collapsed AFM lifter causes sudden ticking, a flashing check-engine light with misfires on cylinders 1/4/6/7, and often camshaft damage. Repairs run from a bank of lifters to a full cam-and-lifters job. This is the defining reliability complaint of the EcoTec3 era and the subject of consolidated class-action litigation against GM.

Most affected: 2014–2018 (5.3L and 6.2L)Typical cost: $2,500–$5,000 (lifters/cam); free if caught under the 5-yr/60k powertrain warranty

8L90 8-speed torque-converter shudder

moderate

Trucks with the 8-speed (6.2L from 2015; some 5.3L trims 2017–2018) develop a highway-speed shudder that feels like driving over rumble strips, traced to the factory Dexron HP fluid absorbing moisture. GM's fix is TSB 18-NA-355: flush with Mobil 1 Synthetic LV ATF HP (blue label). Persistent cases got torque converters under warranty; a class action (Francis v. GM) covered 2015–2019 8L45/8L90 vehicles.

Most affected: 2015–2018 (8L90-equipped)Typical cost: $300–$500 fluid exchange; torque converter $1,800–$3,000 out of warrantyRecall/TSB: TSB 18-NA-355

A/C condenser cracks / refrigerant loss

moderate

The A/C condenser commonly cracks at the top passenger-side end tank or its tube joints, and the A/C gradually or suddenly stops cooling. It is common enough that condensers are a routine stock item; GM extended goodwill on some trucks and redesigned the part. Expect a condenser, receiver/drier function check, and a recharge.

Most affected: 2014–2017 (complaints run into 2019 LD)Typical cost: $400–$800 parts and labor

"Chevy shake" driveline vibration

moderate

A subset of 2014–2016 trucks exhibit a persistent 55–75 mph vibration owners call the Chevy shake. Documented causes include out-of-round tires, driveshaft balance, and torque-converter shudder overlapping. GM issued multiple PIT/TSB documents (tire force-variation matching, driveshaft replacement). Some trucks were bought back; many were improved but not cured. Road-force balancing is the first step.

Most affected: 2014–2016Typical cost: $150 (road-force balance) to $1,500+ (driveshaft)

Console/dash electrical gremlins from corroded ground or weak battery

minor

Flickering gauges, random warning chimes, and infotainment reboots on these trucks very often trace to a marginal battery or the chassis ground behind the driver-side frame rail. Load-test the battery and clean grounds before chasing modules, a classic K2XX pattern in owner forums.

Most affected: 2014–2018Typical cost: $0–$250
