On the 2023-2025 Buick Encore GX, on later Encore GX models the Lane Keep Assist with Lane Departure Warning system applies an inappropriate steering torque that pulls the vehicle across the centerline rather than back into the lane. NHTSA complaints describe a sudden, forceful takeover of the steering wheel toward oncoming traffic, requiring the driver to fight the system. CarComplaints lists Lane Assist as the leading reported problem on the 2025 model year. The behavior appears tied to camera misinterpretation of lane markings - faded lines, tar seams, construction striping, shadows and crest transitions - compounded by camera calibration that was never performed or was performed incorrectly after a windshield replacement.

This issue also affects: Cadillac XTS, Cadillac Escalade, Chevrolet Bolt EUV

Common Symptoms

  • Steering wheel jerks or grips forcefully toward the centerline
  • Vehicle steers toward oncoming traffic without driver input
  • Repeated false lane departure alerts on clearly marked roads
  • System activates over tar seams or old lane markings
  • Behavior worsened after a windshield replacement

How to Fix

Have the front camera module recalibrated - this is mandatory after any windshield replacement and is the most common root cause of biased lane centering. Verify the camera's mounting bracket is fully seated and the windshield in front of it is free of distortion or an aftermarket tint strip, and confirm the vehicle is on the latest camera/ADAS module software, since GM addresses lane-centering behavior through calibration files. Check tire pressures and alignment, because a mechanical pull the system compensates for changes its torque output. Until it is corrected, Lane Keep Assist can be disabled through the vehicle settings menu; report the incident to NHTSA, since ADAS defects are only investigated when complaint volume builds.

On the 2020-2025 Buick Encore GX LIH 1.2L Turbo I3 with VT40 CVT, separate from the well-known low-speed shudder, the VT40 continuously variable transmission suffers hard failures of the line-pressure control solenoid circuit. When the solenoid sticks off, the belt-and-pulley set loses clamping pressure, the transmission cannot transmit torque, and the vehicle abruptly stops accelerating - owners describe engine RPM climbing with no forward motion, or being unable to exceed 20 mph with the pedal floored, sometimes on a highway. Failures are reported between roughly 40,000 and 83,000 miles, and multiple NHTSA complaints describe a second failure after an earlier transmission replacement. Some units have been found with essentially no fluid in the sealed case at teardown.

This issue also affects: Buick Enclave, Buick Envision, Buick Regal

Common Symptoms

  • Vehicle will not accelerate past ~20 mph with pedal fully depressed
  • Engine revs but vehicle does not move
  • Delayed engagement when shifting into Drive or Reverse
  • Loud whine or mechanical noise from the transaxle
  • Sudden jerk followed by loss of drive at highway speed
  • Speedometer rising and falling erratically

How to Fix

Do not clear the code and keep driving; continued operation with low line pressure destroys the belt and pulleys. Retrieve P2714/P0700 and check line pressure and fluid condition. In GM practice this is almost always resolved by transmission replacement or a remanufactured unit rather than a solenoid-only repair, because by the time the code sets the variator surfaces are already damaged. Insist on documentation of the fluid fill and level check on the replacement unit, since dry-at-delivery units have been reported. Verify powertrain warranty coverage (5yr/60,000 mi) before authorizing repair.

Typical repair cost:$4,500 - $7,800

On the 2020-2025 Buick Encore GX, the single-scroll turbocharger used on both the 1.2L LIH and 1.3L L3T three-cylinder engines suffers wastegate actuator and internal turbo failures. The electric wastegate actuator loses calibration or the linkage binds from heat cycling and carbon, so the ECM can no longer hold commanded boost. The module sets an underboost fault, drops the vehicle into a reduced-power limp mode, and in the worst cases the turbo center section itself fails. NHTSA complaints on the Encore GX and its platform twin (Chevrolet Trailblazer) repeatedly describe the failure recurring after a first turbo replacement, indicating the replacement part shares the same weakness. Owners commonly report it first appearing under highway load or when merging.

This issue also affects: Buick Cascada, Buick Encore, Cadillac CT6

Common Symptoms

  • "Engine Power Is Reduced" message on the driver information center
  • Check engine light with sudden loss of acceleration
  • Vehicle will not exceed roughly 35 mph in limp mode
  • Shaking or trembling under load above 35 mph
  • Whistling or siren-like noise from the engine bay under boost
  • Repeat failure after a prior turbo replacement

How to Fix

Scan for P0299 and check actual vs. commanded boost with a scan tool before parts are thrown at it. Inspect the charge-air piping and intercooler couplers for split boots and the PCV/oil separator for excessive crankcase pressure, which drives oil into the turbo. If the wastegate actuator is out of calibration, GM's remedy is actuator/turbo assembly replacement and a relearn; a leaking or shaft-play turbo requires the full turbocharger assembly. Address any charge-pipe leak first, since a boost leak throws the same code far more cheaply.

Typical repair cost:$900 - $2,400
