Both the Encore and the CX-30 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all-wheel drive, collision warning systems, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.

The Encore comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The CX-30’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Buick’s powertrain warranty covers the Encore 1 year and 10,000 miles longer than Mazda covers the CX-30. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the CX-30 ends after only 5 years or 60,000 miles.

The Encore’s corrosion warranty is 1 year longer than the CX-30’s (6 vs. 5 years).

There are almost 4 times as many Buick dealers as there are Mazda dealers, which makes it much easier should you ever need service under the Encore’s warranty.

The Buick Encore’s engine uses a cast iron block for durability, while the CX-30’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Encore’s reliability 27 points higher than the CX-30.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Buick 11th in initial quality, above the industry average. With 2 more problems per 100 vehicles, Mazda is ranked 12th, below the industry average.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Buick vehicles are more reliable than Mazda vehicles. J.D. Power ranks Buick fifth in reliability, above the industry average. With 41 more problems per 100 vehicles, Mazda is ranked 21st.

The Encore has 1.3 gallons more fuel capacity than the CX-30 AWD’s standard fuel tank (14 vs. 12.7 gallons), for longer range between fill-ups.

The Encore has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The CX-30 doesn’t offer a cap-less fueling system.

The Encore Essence’s standard easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The CX-30 doesn’t offer an easy entry system.

The power windows standard on both the Encore and the CX-30 have locks to prevent small children from operating them. When the lock on the Encore is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-30 prevents the driver from operating the other windows just as it does the other passengers.

To improve rear visibility by keeping the rear window clear, the Encore has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the CX-30 only has an intermittent setting, so in a hard rain visibility isn’t as good.

The Encore’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. The CX-30 doesn’t offer heated side mirrors.

On extremely cold winter days, the Encore Essence’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The CX-30 doesn’t offer a heated steering wheel.

The Encore (except Bae) offers an optional 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The CX-30 doesn’t offer a house-current electrical outlet.
