2019 GMC Acadia Problems

Half of the owners who gave a mileage had the problem by about 50,000 miles.

What to check before you buy

• Drive it from cold if you can. Shifts should be smooth in every gear, including reverse.
• Feel for slipping (revs rise without the car speeding up), shudder at low speed and a delay when you put it in gear.
• Listen for whining, which is a common CVT complaint, and clunks when you go from drive to reverse.
• If it has 4WD or AWD, engage it on the test drive and ask when the transmission and differential fluids were last changed.

What to check before you buy

• Test every switch: windows, locks, mirrors, seat heaters, the screen, the backup camera, Bluetooth and every USB port.
• Watch the dash at startup. Every warning light should come on briefly and then go out.
• Have the battery and charging system tested. A weak alternator or battery drain shows up here.

When putting the vehicle in park to turn it off, the dash indicates that I need to put the vehicle in park. But it is in park and it will not let me shut off the vehicle.Owner complaint, filed 2026

This vehicle has an electrical deficiency when trying to park, The console will NOT recognize that the vehicle is in park, causing bell warnings, beeping, and an INABILITY to lock the vehicle, thus draining the battery. We cannot walk away from it, nor ever leave anything of value in it. This is a recurring problem, causing stress, and…Owner complaint, filed 2026

Half of the owners who gave a mileage had the problem by about 52,000 miles.

What to check before you buy

• Ask the seller not to warm the car up, and start it cold. Listen for ticking, knocking or a rough idle in the first minute.
• Pull the oil dipstick and the oil cap. Low oil, a gasoline smell or a milky film on the cap are reasons to walk away or get an inspection.
• Plug in an OBD2 scanner. Stored or pending codes matter, and so do readiness monitors that show "not ready", which usually means the codes were cleared right before the sale.
• Ask for oil change records. A gap in the records on a model known for engine complaints is a negotiating point at minimum.

What to check before you buy

• Turn the wheel lock to lock while parked and listen for groaning, clicking or binding.
• On a straight road the car should track straight with the wheel centered and no loose feeling.

My check engine light is on there is a note that says steering assist is reduced. I took it to O’Reilly’s to get it scanned. The code that comes up is P0128 indicating that the coolant thermostat has a fault. There are other GMC‘s that have a recall for this, but apparently not mine.Owner complaint, filed 2026

The steering assist message comes on and off whenever the weather gets cold in the fall and winter. This causes my air conditioning and/or heater to not work.

Half of the owners who gave a mileage had the problem by about 21,000 miles.

What to check before you buy

• The pedal should feel firm and the car should stop straight without pulling, grinding or a pulsing pedal.
• The ABS and stability control lights should go out after startup and stay out.
• Look through the wheels at the rotors. A deep lip on the edge means brakes are due soon, which is a fair thing to negotiate on.

• Where it is safe, try the adaptive cruise and lane keeping on the test drive and watch for sudden braking or warnings with nothing there.
• Check the windshield in front of the camera and the bumper sensors for cracks, chips or poor repairs.
• Ask whether the windshield has been replaced. The camera has to be recalibrated afterward, and many shops skip it.

The headlights barely light up enough roadway to be of any use at night. Obviously can't drive with high beams constant. The only help is to use the fog/driving lights. However, that only lights up about 30 feet in front of the vehicle. Driving at night is hazardous to one's health as you cannot see far enough down the road to avoid…Owner complaint, filed 2022

What to check before you buy

• Drive over a few bumps and potholes slowly with the radio off and listen for clunks or rattles.
• Check the tires for uneven wear on the inside or outside edges, a sign of alignment or suspension trouble.

What to check before you buy

• Look underneath with a flashlight. Utah road salt is hard on frames, brake lines and the bottoms of doors.
• Open and close every door, the hood and the liftgate, and lock and unlock each one.
• Use a paint thickness gauge and compare panels. A panel that reads very differently from the rest has likely been repaired.
