2011 Chevrolet Express

The 2022-2023 Express vans equipped with the 4.3L V6/8-speed automatic or 2.8L turbodiesel/8-speed automatic combinations have defective transmission control module (TCM) software. The software error can cause harsh shifting, sudden deceleration, and the vehicle moving in an unintended direction from a stop. GM received 18 harsh shifting complaints and 5 sudden deceleration reports.

GM recall affecting 54,722 Express units. Dealers reprogram the TCM with updated software that corrects the shift logic. The repair is performed free of charge.

The transmission control valve can fail, causing a brief lockup of the rear wheels or a sudden change in vehicle direction at low speed. This is related to the TCM software issue but involves physical wear in the transmission control valve body. The condition is most likely to occur during low-speed maneuvers.

GM safety recall for TCM software update and, if wear is detected, transmission control valve body replacement. Dealers install updated software that monitors valve performance and detects excessive wear before lockup can occur.

Express vans equipped with the 6.6L gas V8 engine may have a wiring harness susceptible to short circuits. If a short occurs, drivers may receive a low battery voltage warning, the battery may die, or in worst cases, a fire can start in the engine compartment. This is a serious safety concern, especially for fleet and commercial operators.

GM recall for inspection and replacement of the affected wiring harness section. Dealers install protective conduit over the vulnerable wiring to prevent chafing and short circuits. Free of charge under recall.

The Express is based on a platform dating back to 1996, and the 2022 model retains many legacy components. Owners report issues with door hinge and latch mechanisms, rust in the rear cargo area and undercarriage, power window regulator failures, and cooling system leaks from the water pump and radiator. ABS module failures are also common.

Replace door hinges and latches as they wear. Apply rust prevention treatment to the undercarriage. Replace the water pump and radiator hoses as preventive maintenance. ABS module repair or replacement for brake warning light issues.

Owners report check engine lights related to the evaporative emissions (EVAP) system, including faulty purge valves and gas cap seal failures. The fuel level sensor can also malfunction, causing inaccurate fuel gauge readings. On diesel-equipped models, the diesel exhaust fluid (DEF) system can trigger derate conditions.

Replace the EVAP purge valve and gas cap. Replace the fuel level sending unit for inaccurate gauge readings. For diesel models, DEF injector and tank heater replacement may be needed. Clear and relearn the ECM fuel trims after repairs.

General Motors LLC (GM) is recalling certain 2009-2014 Chevrolet Silverado HD and GMC Sierra HD, 2009 GMC Topkick 5000, 6000, 7000 and 8000 Series and Isuzu F Series, and 2009-2018 Chevrolet Express, and GMC Savana vehicles, equipped with certain Plastic-Handle Fire Extinguishers or Push Button 'Pindicator' Fire Extinguishers. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.

In the event of a fire, if the fire extinguisher does not function properly, it can increase the risk of injury.

GM will notify owners, instructing them to contact Kidde to get a replacement fire extinguisher, free of charge. The recall began June 11, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020, GMC customer service at 1-800-462-8782, and Isuzu customer service at 1-866-441-9638. GM's number for this recall is 18146.

General Motors LLC (GM) is recalling certain model year 2011-2014 Chevrolet Express compressed natural gas (CNG)vehicles manufactured September 10, 2010, to April 28, 2014, and GMC Savana CNG vehicles manufactured May 23, 2011, to April 21, 2014. The affected vehicles may leak natural gas from the CNG high pressure regulator.

A natural gas leak in the presence of an ignition source increases the risk of a fire or explosion.

GM will notify owners, and dealers will replace the high pressure regulator, free of charge. The recall began February 13, 2013. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 14321.

General Motors LLC (GM) is recalling certain model year 2009-2014 Chevrolet Express and GMC Savana vans manufactured January 27, 2009, through March 7, 2014 with a gross vehicle weight rating of 10,000 pounds and less and equipped with front passenger air bags. In the affected vehicles, during a frontal impact below the air bag deployment threshold, if an unbelted front passenger's head hits the instrument panel above where the passenger air bag is located, the panel may not sufficiently absorb the impact. As such, these vehicles fail to meet the requirements of Federal Motor Vehicle Safety Standard number 201, "Occupant Protection in Interior Impact."

In the event of a crash below the air bag deployment threshold, an unbelted front passenger seat occupant has an increased risk of injury.

GM will notify owners, and dealers will modify the passenger instrument panel free of charge. Notices to the owners of the heavy duty vans were mailed on April 28, 2014. The recall began on May 19, 2014. Chevrolet owners may call 1-800-630-2438. GMC owners may call 1-866-996-9463. GM's number for this recall is 14082.

General Motors LLC (GM) and IMPCO Automotive Division of IMPCO Technologies, Inc. (IMPCO) are recalling certain model year 2011-2013 Chevrolet Express and GMC Savana Cargo vans that have a compressed natural gas (CNG) fuel system installed as original equipment by IMPCO. The fuel systems, manufactured February 14, 2011, through February 20, 2013, have a fuel shut-off solenoid connector to the CNG tank that may corrode and form a short.

A short at the connector may cause overheating, resulting in an increased risk of fire.

GM will notify owners and GM dealers/fleets will perform the remedy which will include replacing the solenoid assemblies and fuel pump fuses and adjusting the wiring routing. The recall began on August 5, 2013. GM's number for this recall is 13139. Impco's number for this recall is FA13GM001. Owner's may contact GM Fleet Action Center at 1-800-353-3867.

General Motors is recalling certain model year 2011 Chevrolet Express vehicles converted by Impco Automotive to run compressed natural gas (CNG), manufactured between November 23, 2010 and December 23, 2010 and equipped with a four tank configuration using a pressure relief device (PRD) and pressure relief vent pipe assembly. In the affected vehicles, the pressure relief vent pipe assembly may have been built incorrectly.

If a pressure relief device activates with an improperly assembled vent pipe, compressed natural gas may be vented into the passenger compartment. If an ignition source is present, an explosion or fire may result.

Impco Automotive, in cooperation with General Motors will inspect and make any necessary repairs on the pressure relief device and vent pipe assembly. The safety recall began on March 28, 2013. Owners may contact General Motors at 1-800-521-7300.
