GMT900 Silverado 1500 problems (2007–2013)

Passenger front air bag inflator recall (non-desiccated PSAN) (2007–2013)

Safety recall
Generation:
GMT900 (2007–2013)
Years:
2007–2013
Powertrain:
All engines

GM recalled certain 2007–2013 Silverado 1500 trucks because the passenger frontal air bag inflator uses a non-desiccated ammonium nitrate propellant that can degrade after long exposure to heat and humidity and rupture in a crash. The campaign was split by model year and by climate zone (hot, humid states first), so 21V-050 is one of several related campaigns (21V-051 through 21V-054 cover later years). Dealers replace the inflator free of charge.

Symptoms

  • No warning signs; the inflator can look and work normally until a deployment

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order
  • Note where the truck has been registered: hot, humid states were prioritized

4-speed 4L60-E automatic wear (early GMT900) (2007–2010)

Major repair
Generation:
GMT900 (2007–2010)
Years:
2007–2010

Early GMT900 trucks with the older 4-speed 4L60-E are prone to wear under towing and heat; owners and repair shops commonly report a broken reaction sun shell that takes out reverse and some forward gears. GM moved these trucks to the 6-speed 6L80 over the generation, so check which transmission a given truck has.

Symptoms

  • Loss of reverse, 2nd or 4th gear
  • Slipping or flare on the 2–3 or 3–4 shift
  • Burnt-smelling fluid

Check before buying

  • Confirm which transmission is fitted from the glovebox RPO label or build records
  • Test reverse and every forward gear when warm
  • Ask for transmission service or rebuild records

Oil consumption on the Gen IV 5.3L (LC9) (2011–2013)

Moderate
Generation:
GMT900 (2011–2013)
Years:
2011–2013

A class action certified in 2020 covered 2011–2014 GM trucks and SUVs with the LC9 5.3L built on or after February 10, 2011, alleging the piston rings did not hold enough tension to keep oil out of the combustion chamber. In October 2022 a federal jury returned a $102.6 million verdict for owners in three states. Excess oil burning can foul plugs and build carbon, and GM ended the engine after 2014.

Symptoms

  • Needing to add a quart or more between oil changes
  • Low-oil warning between services
  • Fouled spark plugs or misfire codes
  • Blue smoke on start-up

Check before buying

  • Pull the dipstick and ask how often oil is topped up
  • Scan for misfire codes and inspect a spark plug if possible
  • Ask whether pistons or rings were ever replaced under warranty

K2XX Silverado 1500 problems (2014–2018)

AFM/DFM valve lifter failure on the 5.3L and 6.2L V8 (2014–present)

Major repair
Generation:
K2XX and T1XX (2014–present)
Years:
2014–present

Cylinder-deactivation lifters (Active Fuel Management, later Dynamic Fuel Management) can stick or collapse, which usually damages the camshaft as well. A class action filed in 2021 (Harrison v. GM, E.D. Michigan) alleges the lifters on 2014-and-later 5.3L, 6.0L and 6.2L V8s are defective and that GM’s replacement parts share the flaw. GM has not issued a lifter recall, and owners report repairs that involve replacing lifters and the cam.

Symptoms

  • Persistent ticking from the top of the engine
  • Misfire codes, often on one cylinder bank
  • Hesitation, stumbling or loss of power
  • Shudder when the engine switches between V8 and V4/deactivation modes

Check before buying

  • Listen at idle and under light throttle for a lifter tick
  • Scan for stored misfire codes
  • Ask for invoices showing lifter, camshaft or valve-train work

8-speed automatic torque-converter shudder (2015–2018)

Moderate
Generation:
K2XX (2015–2018)
Years:
2015–2018

GM bulletin 18-NA-355 addresses a shake or shudder at steady 25–80 mph under light throttle, which owners often compare to driving over rumble strips. GM traced it to torque-converter clutch shudder and prescribes a full fluid exchange to a revised Mobil 1 Synthetic LV ATF HP fluid; topping off or mixing fluids will not fix it. The bulletin lists 2015–2018 Silverado models with the L83, L86 and L8B engines.

Symptoms

  • Rumble-strip vibration at 25–80 mph with light throttle
  • Shudder that comes and goes as the converter locks
  • Harsh or clunky shifts in some trucks

Check before buying

  • Drive at a steady 40–60 mph on a smooth road and feel for vibration
  • Ask whether the 18-NA-355 fluid exchange (or a converter replacement) was done
  • Check fluid service records

Reduced brake assist from the engine vacuum pump (recall) (2014–2018)

Safety recall
Generation:
K2XX (2014–2018)
Years:
2014–2018
Powertrain:
5.3L and 6.2L V8

NHTSA recall 19V-645 covered 2014–2018 Silverado 1500 trucks because the mechanical vacuum pump’s output can drop over time, leaving less power brake assist. About 3.46 million US vehicles were included. Dealers reprogram the Electronic Brake Control Module so the system switches to hydraulic brake assist when vacuum falls; a follow-up recall, 20V-603, added more 2018 trucks and SUVs.

Symptoms

  • Firm brake pedal that needs more effort than usual
  • Longer stopping distance
  • Brake-assist warning messages

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order
  • Confirm both 19V-645 and, for 2018 models, 20V-603 are closed

Unintended one-wheel braking if a wheel-speed sensor fails (recall) (2014–2018)

Safety recall
Generation:
K2XX (2014–2018)
Years:
2014–2018

Recall 19V-761 covers 2014–2018 Silverado 1500 trucks with the 5.3L, a 3.08 rear axle and four-wheel drive. If a wheel-speed sensor fails between 41 and 60 mph in 4WD or Auto mode, the brake module’s driveline-protection logic can brake the opposite wheel and pull the vehicle to one side. Dealers reprogram the brake module.

Symptoms

  • Sudden pull to one side in 4WD/Auto mode
  • ABS or traction-control warning with a wheel-speed sensor code

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order

T1XX Silverado 1500 problems (2019–present)

Driveshaft joint weld can separate (recall) (2019–2020)

Safety recall
Generation:
T1XX (2019–2020)
Years:
2019–2020
Powertrain:
All engines

Recall 20V-650 covers certain 2019–2020 Silverado 1500 trucks (and some 2020 Silverado 2500s) because a driveshaft joint may not have been welded properly and can separate while driving, causing a loss of drive. Dealers replace the driveshaft.

Symptoms

  • Vibration or clunk from under the truck
  • Sudden loss of drive to the wheels

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order

6.2L L87 V8 connecting rod/crankshaft defect (recall 25V-274) (2021–2024)

Safety recall
Generation:
T1XX (2021–2024)
Years:
2021–2024
Powertrain:
6.2L V8 (L87)

GM recalled certain 2021–2024 Silverado 1500 trucks with the 6.2L L87 because connecting rod and crankshaft parts from supplier manufacturing defects can lead to engine damage and failure; the recall covers engines built March 1, 2021 to May 31, 2024. Dealers inspect the engine and repair or replace it; engines that pass get thicker 0W-40 oil, a new oil filter and fill cap, and an owner’s manual update. NHTSA has kept investigating: EA25007 (October 2025) looked at failures outside the recall scope, including 2019–2020 trucks, and EA26005 (2026) is examining failures after the remedy and in L87 engines built after the recall period. The 6.2L is common on RST, LTZ, High Country, Trail Boss and ZR2 trucks.

Symptoms

  • Knocking or rod-knock noise that rises with rpm
  • Low oil pressure warning
  • Metal debris in the oil
  • Sudden loss of power or engine seizure

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order
  • Ask whether the engine passed inspection or was replaced, and confirm 0W-40 oil is being used
  • Listen for knocking on a cold start and under load

Rear-wheel lockup from the 10-speed control valve (diesel recall) (2020–2022)

Safety recall
Generation:
T1XX (2020–2022)
Years:
2020–2022

Recall 24V-797 covers 2020–2022 diesel trucks (and 2021 diesel SUVs) because a transmission control valve can fail and lock the rear wheels while driving. Dealers install new transmission software that also detects a bad valve, and GM added special coverage to repair transmissions the software flags. Recall 26V-083 (1,055 vehicles) re-does trucks that received the wrong software under the first campaign.

Symptoms

  • Sudden rear-wheel lockup or skid
  • Transmission warning or limp mode
  • Harsh downshift or bang from the drivetrain

Check before buying

  • Run the VIN through NHTSA’s recall lookup and confirm the remedy shows as complete
  • Ask the dealer for the recall repair order
  • On 2020–2022 trucks, also confirm 26V-083 does not apply or is complete

Frequently asked questions

What years of Silverado 1500 are affected by the 6.2L engine recall?

Recall 25V-274 covers 2021–2024 Silverado 1500 trucks with the 6.2L L87 built from March 1, 2021 to May 31, 2024. NHTSA’s EA26005 investigation is also reviewing later L87 engines and post-repair failures.

Does the Silverado 1500 have lifter problems?

A pending class action alleges AFM/DFM lifters on 2014-and-later 5.3L and 6.2L V8s fail prematurely. GM has not recalled them, so check repair records and listen for a ticking valvetrain.

Which Silverado 1500 years burn oil?

The Gen IV 5.3L (LC9) used through 2013 in the Silverado was the subject of a class action over piston rings, ending in a $102.6 million verdict in 2022.

How do I fix 8-speed shudder on a 2015–2018 Silverado?

GM bulletin 18-NA-355 calls for a full fluid exchange to revised Mobil 1 LV ATF HP fluid. A simple top-off or drain-and-fill with old fluid will not cure it.

Was the 2014–2018 Silverado brake assist issue recalled?

Yes. Recall 19V-645 reprograms the brake control module to add hydraulic assist when vacuum drops, and 20V-603 extended it to more 2018 trucks.
