The 2016 Buick Verano shares GM's Delta II platform with the Cruze and suffers from several serious powertrain issues, particularly catastrophic engine failures on the 2.4L and transmission cooling problems. These aren't minor niggles—some owners face complete engine rebuilds before 100k miles.
Symptoms: Severe knocking or rod knock noise from bottom end, Metal shavings in oil during changes, Sudden loss of oil pressure, Check engine light with misfire codes, Complete engine seizure in worst cases
Fix: This is the big one—piston ring land failure or spun bearings requiring complete engine rebuild or replacement. We're talking 18-25 labor hours for a short block swap, more if you're doing a full rebuild with machine work. The 2.4L has known issues with oil consumption leading to starvation and bearing damage. Some fail from piston ring carbon buildup causing detonation.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Failure and Cooler Contamination
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Transmission fluid leaking near radiator area, Pink/red fluid mixed with coolant in overflow tank, Transmission slipping or harsh shifts, Overheating transmission temp warnings, Milky appearance in transmission fluid
Fix: The external cooler lines corrode and rupture, or the internal cooler in the radiator fails allowing cross-contamination. If coolant gets into the trans, you're looking at a full flush minimum, often a complete transmission replacement if contamination damage occurred. Line replacement alone is 2-3 hours, but trans replacement with contamination is 8-12 hours plus flushing all cooling system components.
Estimated cost: $400-800 (lines only), $3,500-5,000 (with trans replacement)
Ignition System Failures (Coil Packs and Control Module)
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Random misfires across multiple cylinders, Rough idle and hesitation on acceleration, Check engine light with P0300-P0304 codes, No-start condition in severe cases, Engine shaking or vibration at idle
Fix: GM issued a recall for ignition control module software, but coil packs themselves fail frequently on this platform. Each coil is about 0.3-0.5 hours labor, but you typically replace all four at once (2 hours). If the ICM is bad, that's another 1.5-2 hours for diagnosis and reprogramming.
Estimated cost: $400-800
Transmission Mounts Collapsing
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking noise when shifting from Park to Drive/Reverse, Excessive vibration during acceleration, Visible engine/trans movement when revving in Park, Rubbing or contact noises from engine bay during hard acceleration
Fix: The hydraulic transmission mount fails commonly on this platform. It's a 2-3 hour job requiring subframe support and careful alignment during reinstallation. Not safety-critical but gets annoying and can cause other wear if ignored.
Estimated cost: $350-550
Turbo Wastegate Actuator Failure (2.0T models)
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: P0299 code (turbo underboost), Significant loss of power and acceleration, Turbo whining or rattling noises, Limp mode activation, Black smoke from exhaust under load
Fix: The electronic wastegate actuator fails or the rods seize. Sometimes you can replace just the actuator (3-4 hours), but often the entire turbo needs replacement (6-8 hours). Less common than the 2.4L problems but the 2.0T isn't bulletproof either.
PCV System and Intake Valve Carbon Buildup (Both Engines)
Common · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Rough idle that worsens over time, Reduced fuel economy, Hesitation or stumbling on acceleration, Higher-than-normal oil consumption, P0171/P0174 lean codes
Fix: Direct injection engines with no port injection = carbon accumulation on intake valves. PCV valve and hoses fail causing excessive crankcase pressure and oil consumption. PCV fix is 1-2 hours, walnut blasting the valves is 4-6 hours. Should be done preventatively every 60-80k miles.
Check oil level every 1,000 miles on the 2.4L—consumption issues lead to catastrophic failure if ignored
Change transmission fluid every 50k miles and inspect cooler lines for corrosion annually
Budget $500-1,000/year for unexpected repairs after 80k miles—these aren't Honda Accords
Run a pre-purchase inspection including oil analysis and compression test—hidden engine damage is common
Consider an extended warranty if buying used; powertrain failures are expensive and not rare
Pass on high-mileage examples unless you see meticulous service records and fresh engine/trans work—too many expensive grenades waiting to go off for typical used-car money.

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. Also, certain 2013 Buick Encore, 2011 Buick Regal, 2013-2014 Buick Verano, 2011-2016 Chevrolet Cruze, 2010-2013 Chevrolet Equinox 2013-2015 Chevrolet Malibu, and 2011-2013 GMC Terrain vehicles may have been serviced with similar defective replacement electronic park lock levers. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 114, "Theft Protection and Rollaway Prevention."
Consequence: If the key is removed without the transmission in PARK, the vehicle may rollaway as occupants are exiting, increasing the risk of injury.
Remedy: 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.
