What stands out
Of the 5 model years of Buick Verano we track for electrical problems, this one has the fewest owner complaints on file (12).
Electrical accounts for 20% of all owner complaints filed against this vehicle, across 6 categories tracked.
General Motors LLC (GM) is recalling certain model year 2016-2017 Buick Verano and 2016 Chevrolet Malibu as the electronic park lock lever may allow the ignition key to be removed without the transmission being in PARK
If the key is removed without the transmission in PARK, the vehicle may rollaway as occupants are exiting, increasing the risk of injury.
Fix: GM will notify owners, and dealers will inspect and if necessary replace the key cylinder lock housing, free of charge. The recall began on October 14, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020, Buick 1-800-521-7300, and GMC 1-800-462-8782. GM's number for this recall is 50490 and 50491.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Service Bulletin25-NA-087Apr 2025
This service bulletin provides information on the proper Reflective High Temperature Heat and/or Insulating Tape to use for certain repairs, such as Wiring Harness Repairs.
The intent of this service bulletin is to identify aftermarket ALDL or DLC interface devices as potential sources for causing multiple customer concerns that do not have other diagnostic methods to identify them.
This service bulletin provides information for dealers/technicians on Service Programming System (SPS) Error Codes E4398, E4399, E4401, E4403, M4404, M4413, M6954, M6955, E4414, E4423, E4491, E4492, or E6961 and resolution information.
This service bulletin provides information to diagnose batteries that have set for a long period of time and/or cold weather climates and testing those batteries.
This bulletin advises the dealers to maintain the vehicle stock on hand by doing a full inspection on the vehicles before being sold (prepping) to the customer.

The failure pattern owners describe
Owners of the 2016 Buick Verano report a pervasive electrical defect pattern affecting critical and convenience systems. The most dangerous failures are sudden power loss while driving—the engine stalls, power steering cuts out, and the vehicle nearly stops on interstates. Multiple owners describe near-misses and stalling at highway merge speeds. One owner reports the intake cam solenoid valve failed with no warning light, causing total loss of acceleration on I-20. Dealers cannot replicate these events and dismiss them as unfixable without a stored code.
The side detection module corrodes and blows a fuse, cascading into complete gauge failure (speedometer, tach, fuel, temp), airbag deactivation, and blind-spot-detector shutdown—all mid-drive. One repair ran nearly $2,000. The passenger airbag logic is backwards: it's off when someone sits down with the belt fastened, but on when the seat is empty. Owners also report random radio cutoffs, door locks cycling without input, and battery drain issues. One 2016 Verano caught fire under the driver seat at 5,500 miles while parked overnight; Buick never determined the cause. Dealerships and Buick have ignored owner requests for recalls, citing inability to replicate or offering only parts replacement without addressing the root cause.

Failure modes owners describe
Power loss / stalling / loss of power steering
Engine loses power suddenly while driving, sometimes stalling completely. Power steering is lost simultaneously, creating immediate hazard. Occurs randomly and intermittently.
When: May through August at unspecified mileage; one case at 5,500 miles
Symptoms owners cite: engine stalling on interstate; loss of power steering while driving; random acceleration declines; loss of power even with cruise control active
Codes mentioned:STABILITRAK needs serviced
Repairs/costs cited: Dealership unable to replicate; no repairs completed. Hard shifts from 1st to 2nd gear also reported but dismissed as normal.
Recalls/TSBs owners mention: Dealership stated unable to replicate issue without error code; owner told to return when warning appears. GM has faced prior litigation over similar issues.
Intake cam solenoid valve failure
Intake cam solenoid valve failed abruptly without warning light. Vehicle could not accelerate and nearly stalled on interstate during merge.
When: Unspecified mileage; failure occurred while on interstate
Symptoms owners cite: no acceleration capability; near-complete stop on interstate; engine cut off at gas station; no warning light before failure
Repairs/costs cited: Dealership could not explain cause; vehicle was towed.
Side detection module corrosion and electrical failure
Side obstacle/blind spot detection module becomes corroded, blows a fuse, and stops functioning. Causes cascade of electrical failures affecting multiple systems. Occurs while driving or upon startup. Water exposure is the suspected cause.
When: Unspecified mileage; one case noted at approximately 189,000 miles
Symptoms owners cite: blind spot detection stops working; service side detection warning appears on dash; loss of all gauge functions (speedometer, tachometer, fuel, temp); airbag system failure; turn signals malfunction; camera systems fail; passenger airbag stays OFF with passenger seated
Codes mentioned:SERVICE SIDE DETECTION SYSTEM, SERVICE AIR BAG
Repairs/costs cited: Replacement of side detection module cost approximately $2,000. Reported in service bulletins for some GM vehicles but not covered by recall for Verano.
Recalls/TSBs owners mention: Service bulletin issued for some GM vehicles; extended warranty protection available for some models but NOT Verano. No recall issued.
Airbag system malfunction
Passenger airbag activation logic is incorrect—airbag remains OFF when passenger is seated with seatbelt, but activates when seat is empty. Also reported as airbag module failure requiring replacement.
When: Present since purchase; one module replacement needed at unspecified mileage
Symptoms owners cite: passenger airbag ON when no passenger and seatbelt unbuckled; passenger airbag OFF when passenger seated and seatbelt fastened; airbag warning light illuminates while driving
Codes mentioned:SERVICE AIR BAG
Repairs/costs cited: Airbag module replacement required; described as annoying repair on relatively new vehicle.
Radio on/off malfunction
Radio cuts off and on randomly while driving without user input. Occurs intermittently.
When: May through August; ongoing at 189,000 miles
Symptoms owners cite: radio powers off while driving; radio powers on while driving; radio fails to turn off as commanded
Door lock and electrical control malfunction
Doors lock and unlock independently without user command. Accompanied by radio failure to turn off. Relay and sensors previously replaced but failure persisted.
When: 189,000 miles
Symptoms owners cite: doors lock independently; doors unlock independently; radio will not turn off
Repairs/costs cited: Unknown relay and sensors replaced previously without resolving issue. Vehicle remains unrepaired.
Fire under driver seat
Fire started under driver seat while vehicle was parked unattended at night. Fire burned through seat into driver door, advancing from bottom to window opening.
When: 12/6/2017 night; vehicle at approximately 5,500 miles
Symptoms owners cite: fire initiated under driver seat; seat burned through; driver side door burned; windows smoked over from interior fire; driver door would not open after fire
Repairs/costs cited: Vehicle declared total loss. Fire cause never determined by Buick.
Recalls/TSBs owners mention: As of 1/23/18, Buick determined vehicle is complete loss but did not determine cause and offered no settlement.
Thermostat display malfunction
Temperature display does not show outdoor temperature. Thermostat controls display in Celsius only with no option to switch to Fahrenheit.
When: Present since purchase
Symptoms owners cite: no outdoor temperature display; thermostat shows Celsius instead of Fahrenheit; no user option to change temperature display format
Symptoms owners cite: dead battery; battery saver active warning
Codes mentioned:SERVICE BATTERY CHARGING SYSTEM, BATTERY SAVER ACTIVE
Repairs/costs cited: Dealership attributed to excessive auto-start usage.
Tire pressure monitoring system malfunction
Tire pressure is not reading correctly in the monitoring system.
When: Unspecified
Symptoms owners cite: tire pressure not reading properly
Codes mentioned:SERVICE TIRE MONITOR SYSTEM
