Among the 5 model years of Buick Verano in our records for powertrain problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain 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.
This bulletin provides information on identifying Non-GM Engine Calibrations for Gasoline Engines using the Tech 2 or GDS 2.

The failure pattern owners describe
Owners describe a troubling cluster of powertrain and shift-mechanism failures. Hard shifting occurs at 15–25 mph and 50–60 mph, causing jerking and sluggish acceleration despite dealer diagnostics showing no fault codes. One owner reports elevated idle RPM when the A/C engages, with the engine sitting at 1500 RPM instead of 800, accompanied by loud cooling fans that don't subside.
Shifter problems span mechanical and electrical failures: shift lock release buttons crack, gear shifters become stuck when shifting from Park, and one transmission locked in Reverse after a Check Engine light. A few owners report unintended gear selection—one passenger accidentally switched the transmission to manual at highway speed due to the console lever's proximity to the front seats. A key stuck in the ignition prevented vehicle shutdown and Park engagement. One owner reports the vehicle rolled backward out of a driveway; another notes unintended downshifting at 70 mph following a highway bump.
Several owners report dealers either refusing diagnosis (citing clean diagnostic scans) or offering only partial repairs. The manufacturer has sometimes declined recalls but paid partial repair costs in at least one case. Failures have occurred across a wide mileage range, from 20,000 to 100,000 miles.

Failure modes owners describe
Hard shifting / rough gear engagement
Transmission exhibits delayed or forceful shifts between gears, causing jerking motion and sluggish acceleration. Occurs repeatedly at specific speed ranges but dealer diagnostics show no fault codes.
When: 15–25 mph and 50–60 mph; also reported between 8–17k miles
Symptoms owners cite: Hard shift between gears; Jerking during acceleration; Sluggish acceleration; Engine rev spike during downshift after highway bump
Repairs/costs cited: Attempted fix resulted in 2-month symptom relief before recurring; no permanent resolution documented
Elevated idle RPM and cooling fan noise
Engine idles at 1500 RPM instead of normal 800 RPM when A/C compressor engages, with abnormally loud cooling fans and labored engine sound. Condition persists for 10+ minutes without returning to normal idle.
When: Upon A/C system engagement after remote start
Symptoms owners cite: Idle RPM rises from 800 to 1500 RPM; Loud cooling fan noise; Labored engine sound; High idle does not decrease after 10+ minutes
Repairs/costs cited: Dealer refused repair citing negative diagnostic result
Shift lock release button fracture
Plastic shift lock release button on gear shifter fractured, preventing shift into Park without use of workaround tool. Occurs mid-drive with no impact or known cause.
When: ~60,000 miles
Symptoms owners cite: Shift lock release button fractured; Unable to shift into Park without tool; Able to shift to Neutral
Repairs/costs cited: Independent mechanic diagnosed gear shifter replacement needed; dealer notified but vehicle not repaired
Unintended manual mode engagement
Console-mounted shift lever easily shifted to manual transmission mode by passenger movement or nearby objects (coat, purse) during highway speeds, with no physical guard preventing accidental activation.
When: Highway speeds
Symptoms owners cite: Transmission unexpectedly switched to manual mode; Engine racing while vehicle slowed; Lever easily moved by passenger activity in close quarters
Key stuck in ignition
Ignition key becomes mechanically stuck and cannot be removed while vehicle is running or in Drive/Neutral. Prevents Park engagement and vehicle shutdown. Owner identified similar issue on Chevy Malibu via online forums.
When: Multiple occurrences; February 21, 2019 valet incident
Symptoms owners cite: Key stuck in ignition; Cannot remove key from ignition; Vehicle stuck in Drive/Neutral, unable to shift to Park
Repairs/costs cited: Owner used YouTube technique (similar to Chevy Malibu fix) to remove key; valet unable to resolve
Recalls/TSBs owners mention: Owner believes vehicle may be covered by recall numbers 50490 and 50491
Transmission stuck in Reverse, Check Engine light
During acceleration from stop, Check Engine light illuminated and transmission suddenly shifted into Reverse and locked in that gear. Restarting vehicle restored normal operation.
When: ~52,000 miles
Symptoms owners cite: Check Engine light illuminated; Transmission locked in Reverse gear; Unable to shift out of Reverse until restart
Codes mentioned: Intake cam solenoid fault, Exhaust cam solenoid fault
Repairs/costs cited: Dealer replaced intake and exhaust cam solenoids and updated software
Recalls/TSBs owners mention: Dealer software update and solenoid replacement performed after diagnostics
Gear shifter mechanical failure / stuck in Park detection
Gear shifter fails to engage from Park position, requiring multiple attempts to shift. Shifter button also failed. Separate complaint: shifted into Park but vehicle alerts that it is not in Park, with incorrect gear display.
When: ~38,000 miles; ~20,134 miles for Park detection failure
Symptoms owners cite: Unable to shift from Park (requires multiple attempts); Gear shifter button failure; Vehicle alert states gear not in Park despite shifted to Park; Incorrect gear position displayed
Repairs/costs cited: Shifter assembly replacement needed (confirmed at Greater Lowell Buick dealer)
Recalls/TSBs owners mention: Manufacturer paid portion of repair after diagnosis at dealer
Vehicle rolls in Drive due to lack of hill-hold engagement
Vehicle parked on inclined driveway in Drive (rather than Park) rolled away when unattended. Driver recovered vehicle by applying brakes and shifting to Park. Dealer advised that all Buick vehicles behave the same way when left in Drive on an incline.
When: ~100,000 miles
Symptoms owners cite: Vehicle rolled away while in Drive gear on incline
Recalls/TSBs owners mention: Dealer stated all Buick vehicles perform the same action in Drive on incline; no repair performed
Unintended vehicle movement (rollback)
Vehicle backed itself out of driveway without driver input and struck neighbor's mailbox. No other details provided.
When: Unknown
Symptoms owners cite: Vehicle reversed without driver command; Vehicle rolled backward out of driveway
Transmission downshift lag and engine surge at highway speeds
While traveling at 70 mph over highway bump, warning light illuminated, engine RPM increased sharply as if downshift occurred, and vehicle decelerated noticeably. Warning light disappeared after stopping and checking shifter, which remained in Drive.
When: Highway speeds (70 mph)
Symptoms owners cite: Warning light illuminated; Engine RPM suddenly increased; Transmission appeared to downshift unexpectedly; Vehicle decelerated despite remaining in Drive

What does it cost to fix?
Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to powertrain?
No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
