On the 2007-2023 GMC Acadia, gM customer-satisfaction bulletin 13079 covers certain 2009-2013 GMC Acadia vehicles with 3.6L High Feature V6 engines (RPO LY7 or LLT) that may experience leakage from the water-pump shaft seal, often after operation with low coolant.

This issue also affects: Cadillac XT5, Cadillac XT6, Chevrolet Camaro

Common Symptoms

  • Coolant leak from the water-pump shaft seal

How to Fix

Check the VIN and current eligibility with GMC. Bulletin 13079 directs dealers to verify and correct coolant level with the proper DEX-COOL mixture; it does not establish the frozen claim that the pump is internal or must be combined with timing-chain work.

On the 2022 GMC Acadia, gM recalled certain 2022 GMC Acadia All-Wheel Drive vehicles because the rollover valve in the fuel tank may not provide a proper seal if the vehicle rolls over in a crash. Only AWD Acadias built in the affected population are covered — front-wheel-drive Acadias are not part of this campaign. The valve is a passive safety device: it is supposed to close off the tank vent path when the vehicle is on its side or roof so gasoline cannot escape. In the recalled vehicles the valve can be dislodged or missing entirely, so it cannot seal. NHTSA lists the defect under the fuel storage tank assembly. Because the part only does its job during a rollover, an Acadia can carry this defect for its whole life without the driver ever seeing a sign of it — the consequence is a fuel leak during a rollover crash and an increased risk of fire.

How to Fix

The repair is free at any GMC dealer under recall 22V446000 (GM's internal number N222366070). The dealer inspects the fuel tank and, if the rollover valve is found dislodged or missing, replaces the fuel tank shell. GM mailed owner notification letters on July 27, 2022, so a used-Acadia buyer may never have received one — enter your VIN at nhtsa.gov/recalls to confirm whether the recall is still open on your vehicle. GMC customer service can be reached at 1-800-462-8782.

On the 2022 GMC Acadia, gM recalled certain 2022 GMC Acadia SUVs because the left-rear suspension toe link may have been tightened improperly during assembly. The toe link is what holds the rear wheel's toe angle in place, and if its fastener was not torqued correctly it can work loose or the link can separate entirely. NHTSA campaign 22V427000 covers this defect under GM's internal recall number N222364330, and it is filed under SUSPENSION:REAR. GM states that a loose toe link can separate and cause a loss of vehicle control, increasing the risk of a crash. The same campaign also covers the 2022 Cadillac XT5 and XT6, which share the affected assembly work; the units-affected figure was not stated in the recall record.

Common Symptoms

  • Loose or separated left-rear suspension toe link
  • Loss of vehicle control

How to Fix

Repair is free at any GMC dealer. The dealer inspects the left-rear suspension and replaces the fastener if it is found loose or missing. Owner notification letters were mailed July 11, 2022. If you own a 2022 Acadia and are not sure whether yours was included or whether the work was already performed, run your VIN at nhtsa.gov/recalls, or call GMC customer service at 1-800-462-8782 and reference recall N222364330.

On the 2017-2025 GMC Acadia, the second-generation Acadia (2017+) uses the GM 9T65 9-speed automatic transmission which shares known issues with the Chevrolet Traverse and Blazer. Common complaints include harsh 1-2 upshifts, hesitation between 5-15 mph, lurching on light throttle in stop-and-go traffic, and the transmission hunting between gears on hills. GM has released multiple TCM calibration updates. The transmission is extremely sensitive to fluid condition — extended intervals with aging Dexron HP fluid contribute significantly to shift quality degradation.

This issue also affects: Cadillac XT5, Cadillac XT6, Chevrolet Camaro

Common Symptoms

  • Harsh or jerky 1-2 upshift between 5-15 mph
  • Hesitation when pulling away from a stop
  • Transmission hunting between gears on slight grades
  • Vibration or shudder during light acceleration
  • Delayed engagement from Park to Drive
  • Slip or flare on 2-3 shift under load

How to Fix

TCM recalibration with latest software (multiple revisions released). Full transmission fluid exchange with Dexron HP (ACDelco/GM 19354121) every 45,000 miles. Valve body and solenoid pack replacement (OEM 24043134) if software updates fail. Allow 500+ miles for relearn after any TCM reset.

Typical repair cost:$0 - $3,500
