2021 Chevrolet Traverse Recalls, Issues & Maintenance

The 2021 Chevrolet Traverse carries 3 open NHTSA recalls — most recently covering automatic transmission and frontal impact. Owners report 7 recurring issue clusters, led by “Alternator failure and electrical system shutdown.” Chevrolet vehicles use the GM Oil Life System (OLS) — a percentage-based monitor that calculates oil life from driving conditions, not fixed mileage. When the OLS drops to 0%, oil and filter are due. The schedule below reflects GM's Normal Use intervals for everything else.

POWER TRAIN:AUTOMATIC TRANSMISSION

Campaign #21V817000 · Oct 18, 2021

Issue: Braun Corporation (Braun) is recalling certain 2020-2021 Chevrolet Traverse wheelchair accessible vehicles with Power In-floor Ramp conversion. The screw and clip that hold the inner wheel-well plastic shroud in place may chafe against the transmission case, possibly resulting in a transmission fluid leak.

Risk: A transmission fluid leak can cause a loss of drive power, increasing the risk of a crash. In addition, a leak in the presence of an ignition source increases the risk of a fire.

Fix: Dealers will replace the screw and clip, and inspect for signs of contact with the transmission, free of charge. Owner notification letters were mailed November 29, 2021. Owners may contact Braun customer service at 1-800-488-0359.

AIR BAGS:SENSOR:FRONTAL IMPACT

Campaign #21V472000 · Jun 24, 2021

Issue: General Motors, LLC (GM) is recalling certain 2021 Chevrolet Traverse and Buick Enclave vehicles. During service by dealers, certain vehicles may have received incorrect air bag calibration software that may affect frontal airbag deployment.

Risk: Air bags that do not deploy as intended can increase the risk of injury.

Fix: Dealers will update the air bag calibration software, free of charge. Owner notification letters were mailed on July 29, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020 and Buick customer service at 1-800-521-7300. GM's number for this recall is N212340220.

Campaign #22V210000 · Mar 31, 2022

Issue: General Motors, LLC (GM) is recalling certain 2020-2022 Chevrolet Traverse and 2021-2022 Buick Enclave vehicles. The harness connector to the left or right side roof rail air bag may have incompatible electrical terminals, which could prevent the air bags from deploying in a crash.

Risk: Roof rail air bags that do not deploy as intended increase the risk of injury in a crash.

Fix: Dealers will replace the harness connector to the roof rail air bags, free of charge. Owner notification letters were mailed on April 29, 2022. Owners may contact Buick customer service at 1-800-521-7300 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N212352140.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter (per Oil Life System)

Every 7,500 mi

Change oil when the Oil Life System reaches 0% or every 12 months — whichever comes first. dexos1-approved synthetic oil required on all gas engines since 2011.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 7,500 mi

Rotate tires every 7,500 miles. Silverado 4x4 and Tahoe owners benefit from earlier rotations to even out drivetrain wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 7,500 mi

Inspect brake pads, rotors, and parking brake at each tire rotation. Equinox and Malibu front pads typically last 40,000-50,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 45,000 mi

GM specifies brake fluid replacement based on contamination testing. Test every 30,000 miles; replace if moisture content exceeds 3% or fluid appears dark.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 45,000 mi

GM long-life cellulose air filters are rated 45,000 miles. Direct-injection engines are sensitive to airflow restriction; inspect at every oil change.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Automatic Transmission Fluid

Every 45,000 mi

Severe service (heavy towing, frequent stop-and-go, dusty conditions): replace every 45,000 miles. Normal service: 97,500 miles. Use Dexron-VI on 6L80/8L90 transmissions.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Transfer Case Fluid (4WD)

Every 45,000 mi

Silverado 4WD and Tahoe 4WD: replace transfer case fluid every 45,000 miles, sooner if towing or off-roading. Use GM Auto-Trak II fluid.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

DIY

~$15–$40

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

Spark Plugs

Every 100,000 mi

GM iridium spark plugs are rated 100,000 miles on most LS and LT engines. The 5.3L V8 in Silverado 1500 commonly fouls plugs early under heavy idling.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Dex-Cool Engine Coolant

Every 50,000 mi

GM Dex-Cool (orange): first change at 150,000 miles or 5 years, then every 50,000 miles. Mixing with green coolant creates a sludge that destroys the cooling system.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Rear Differential Fluid

Every 50,000 mi

Silverado and Tahoe: replace rear axle fluid every 50,000 miles, or 25,000 miles if towing. Limited-slip differentials require GM friction-modifier additive.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 22,500 mi

Replace the cabin air filter every 22,500 miles. Silverado and Tahoe owners in dusty climates should replace earlier.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.

FARS counts every occupant death in a fatal crash, whatever the cause — it does not mean the vehicle was at fault or defective. Counts are not adjusted for how many of each vehicle are on the road. How to read this number
