5/5 Overall
NHTSA 5-Star Safety Rating
Steering complaints dominate what 2014 LaCrosse owners report, with multiple drivers describing a "Service Power Steering" warning appearing while underway, followed by a sudden loss of power steering assist that makes the wheel noticeably harder to turn. This tends to happen at highway speeds or while merging, leaving drivers maneuvering with significantly increased steering effort. Electrical system complaints are the next most common, covering a range of behaviors: doors that won't unlock, windows that won't respond, and vehicles that won't start despite the key being present, essentially a loss of basic electrical function all at once. A smaller cluster of airbag complaints rounds out the top reported systems, though those reports don't describe a single consistent symptom pattern. A few owners also mention transmission hesitation and delayed acceleration, particularly when pulling away from a stop or attempting to reverse.

By System
The 2014 Buick LaCrosse has 6 recalls, the most serious being a software defect in the airbag control module that can prevent frontal airbags and seatbelt pretensioners from deploying in a crash, leaving the driver and front passenger without key restraint protection.
A related recall covers the same pretensioner and airbag deployment failure, and prior repair attempts did not fully resolve the issue across all affected vehicles. On the brake side, certain vehicles may have been fitted with a rear brake rotor on the front axle, which runs hotter under braking and wears through brake pads much faster than normal. There are also two electrical concerns: a compliance issue affects the theft protection and power window systems on some vehicles, and a corroding wiring splice in the driver's door can cause the key-in-ignition chime to stop working, removing the audible warning that could prevent a rollaway.
At a glance
What can fail
The air bag control software may not have received a complete update from a previous recall. Under certain driving conditions, this software may run a diagnostic test that disables frontal air bags and seat belt pretensioners during a crash.
What the fix does
Dealers will update the air bag control software. If your vehicle previously deployed air bags, the control module will be replaced instead. Repairs are free.

What can fail
The airbag and seatbelt control module has a software flaw that may prevent frontal airbags and seatbelt pretensioners from deploying during a crash when they should.
What the fix does
Dealers will update the control module's software. If the module has recorded a prior deployment, dealers will replace it with a new module containing updated software.

What can fail
Under certain driving conditions, the air bag control module's software may run a self-test that disables the front air bags and seat belt pretensioners, preventing them from deploying in a crash.
What the fix does
Dealers will update the air bag control module software. If your air bags have previously deployed, the module will be replaced. Repairs are free of charge.

At a glance
What can fail
A corroded or broken wire connection in the driver's door can allow power windows and sunroof to operate even after removing the key, posing injury risk. It may also disable theft warnings.
What the fix does
Dealers will inspect the door wiring harness and install a new splice connection if needed.

At a glance
What can fail
A wiring splice in the driver's door can corrode and break, eliminating the chime that alerts you when the door opens with the key in the ignition. The Retained Accessory Power module may also remain active for ten minutes, allowing continued operation of passenger windows, rear windows, and sunroof.
What the fix does
Dealers will inspect the driver door window motor harness and replace the electrical splice as needed, at no cost to you.

At a glance
What can fail
Some vehicles have a thinner rear brake rotor installed in the front brake assembly instead of the correct front rotor. This causes excessive heat during braking, rapidly wearing brake pads and rotors. As wear increases, the outer brake pad may disengage, reducing braking performance.
What the fix does
Dealers will inspect both front brake rotors and replace them with correct rotors and brake pads as needed.
