2022 Chevrolet Trailblazer

The 1.3L three-cylinder turbocharged engine in the 2022 Trailblazer exhibits significant turbo lag and hesitation during acceleration from a stop, especially when merging into traffic or climbing hills. Owners describe a dead spot when pressing the accelerator, followed by a sudden surge of power when the turbo spools. This behavior is more pronounced when the engine and turbo are cold.

Dealer performs a PCM (Powertrain Control Module) software calibration update to improve throttle response and turbo spool timing. GM released updated shift programming for the CVT to work better with the turbo power delivery. If hesitation persists, inspect the boost pressure sensor, wastegate actuator, and charge air cooler for leaks.

The CVT (Continuously Variable Transmission) paired with the 1.3L turbo exhibits jerking during low-speed driving, shuddering during acceleration, and a whining noise during cruise. Some owners report the transmission hesitating or slipping when pulling away from stops, creating an unnerving delay between pressing the gas and the vehicle moving.

Dealer performs a TCM software update to improve CVT behavior and shift feel. GM released multiple calibration updates for the CVT throughout the 2022 model year. If jerking persists after software updates, the CVT belt and pulleys may need inspection for premature wear. CVT fluid level and condition should also be verified.

The 7-inch or 8-inch infotainment touchscreen freezes, reboots, or goes black during driving. Apple CarPlay and Android Auto connections drop frequently and may fail to reconnect without restarting the vehicle. The rearview camera display can also lag or show a frozen image when the vehicle is shifted into reverse.

Dealer performs infotainment software updates. Performing a system reset by holding the power/volume knob for 10 seconds may resolve temporary freezes. USB cable quality affects CarPlay/Android Auto reliability — use a short, OEM-quality cable. Persistent issues may require infotainment module replacement.

Owners report excessive wind noise around the A-pillar and windshield area, as well as road noise from the rear cargo area at highway speeds. The noise levels are described as significantly louder than competitors in the subcompact SUV class. Some vehicles have poor door seal adhesion that allows wind noise intrusion around the front door windows.

Dealer inspects and adjusts door weatherstripping and window alignment. Additional sound-deadening material can be applied to the doors, floor pan, and cargo area. Verify that the windshield molding and A-pillar trim are properly seated. GM has not issued a formal TSB, but dealer adjustments may be covered under the new vehicle warranty.

The forward collision alert and automatic emergency braking system occasionally activates falsely when no obstacle is present, causing sudden unexpected braking. Owners report phantom braking events on open highways, when driving under overpasses, when passing roadside signs, and in heavy rain or snow. These false activations create a rear-end collision risk from following vehicles.

Dealer performs a recalibration of the forward-facing camera and radar sensors. GM released updated AEB software to reduce false positive detections. Ensure the windshield area around the camera is clean and free of film or obstructions. If the camera module is faulty, it must be replaced and recalibrated using GM's calibration targets.
