Known problems with the 2015 Chevrolet Silverado 1500

5 of the 5 issues we track for the 2014–2018 generation are documented against the 2015 model year, and 1 carries a recall or service bulletin.

• 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.

  Typical cost: $2,500–$5,000 (lifters/cam); free if caught under the 5-yr/60k powertrain warranty

• 8L90 8-speed torque-converter shudder

  moderateTSB 18-NA-355

  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.

  Typical cost: $300–$500 fluid exchange; torque converter $1,800–$3,000 out of warranty

• 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.

  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.

  Typical 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.

  Typical cost: $0–$250
