Safety

For enhanced safety, the front and rear seat shoulder belts of the Lexus UX Series have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Mazda CX-5 doesn’t offer pretensioners for the rear seat belts.

The UX Series has standard Secondary Collision Brake, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CX-5 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The UX Series offers optional Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The CX-5 doesn’t offer backup collision prevention brakes.

The UX Series offers optional Parking Support Alert to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The CX-5 doesn’t offer a front parking aid.

The UX Series’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CX-5 doesn’t offer a driver alert monitor.

Compared to metal, the UX Series’ plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-5 has a metal gas tank.

Both the UX Series and the CX-5 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

Warranty

The UX Series comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The CX-5’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.

Lexus’ powertrain warranty covers the UX Series 1 year and 10,000 miles longer than Mazda covers the CX-5. 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-5 ends after only 5 years or 60,000 miles.

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

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Lexus 8th in initial quality, above the industry average. With 16 more problems per 100 vehicles, Mazda is ranked 22nd, below the industry average.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Mazda vehicles. J.D. Power ranks Lexus first in reliability, above the industry average. With 45 more problems per 100 vehicles, Mazda is ranked 14th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Lexus vehicles are more reliable than Mazda vehicles. Consumer Reports ranks Lexus first in reliability. Mazda is ranked third.

Regenerative brakes improve the UX 250h’s fuel efficiency by converting inertia back into energy instead of wasting it. The CX-5 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the UX Series Hybrid’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The CX-5 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Lexus UX Series uses regular unleaded gasoline. The CX-5 GT Reserve/Signature requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Transmission

The UX Series has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The CX-5 doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the UX Series’ standard front brake rotors are larger than those on the CX-5:

Tires and Wheels

The UX Series’ tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the CX-5 Sport/Touring’s standard 65 series tires. The UX Series’ tires are lower profile than the CX-5 Grand Touring/Signature’s 55 series tires.

For better ride, handling and brake cooling the UX Series has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CX-5 Sport/Touring.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the UX Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The CX-5 doesn’t offer run-flat tires.

Suspension and Handling

For better maneuverability, the UX Series’ turning circle is 1.8 feet tighter than the CX-5’s (34.2 feet vs. 36 feet).

Chassis

The Lexus UX Series may be more efficient, handle and accelerate better because it weighs about 200 to 250 pounds less than the Mazda CX-5.

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the UX Series. The CX-5 doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the UX Series’ liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-5 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mazda. J.D. Power ranks Lexus third in service department satisfaction. With a 85% lower rating, Mazda is ranked 27th.

Ergonomics

The UX Series’ optional easy entry system raises the steering wheel and 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-5 doesn’t offer an easy entry system.

The UX Series’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The CX-5’s passenger windows don’t open or close automatically.

If the windows are left open on the UX Series the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (Your Lexus service department must activate this window function.) The driver of the CX-5 can only operate the windows from inside the vehicle, with the ignition on.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The UX Series offers available headlight washers to keep headlight output high. The CX-5 doesn’t offer headlight washers.

The UX Series has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The CX-5 only offers an automatic headlight on/off feature as an extra cost option.

The UX Series’ standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-5 Grand Touring/Signature.

When the UX Series with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The CX-5’s mirrors don’t automatically adjust for backing.

The UX Series offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The CX-5 offers an automatic rear view mirror, but its side mirrors don’t dim.

The UX Series has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the CX-5 Touring/Grand Touring/Signature.

Both the UX Series and the CX-5 offer rear vents. For greater rear passenger comfort, the UX Series has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The CX-5 doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Lexus UX Series offers an optional wireless phone charging system (Qi) in the center console. The CX-5 doesn’t offer wireless personal charging.
