Safety

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX30 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 Cadillac XT4 doesn’t offer pretensioners for the rear seat belts.

Both the QX30 and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems and around view monitors.

Warranty

The QX30 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The XT4’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX30’s corrosion warranty is 1 year longer than the XT4’s (7 vs. 6 years).

Reliability

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 66 more problems per 100 vehicles, Cadillac is ranked 27th.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than Cadillac vehicles. Consumer Reports ranks Infiniti 22 places higher in reliability than Cadillac.

Transmission

The QX30 offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The XT4 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

The QX30 stops much shorter than the XT4:

Tires and Wheels

The QX30’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the XT4’s standard 60 series tires.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX30 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The XT4 doesn’t offer run-flat tires.

Suspension and Handling

The QX30 Sport handles at .88 G’s, while the XT4 Sport AWD pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The QX30 Sport executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the XT4 Sport AWD (26.1 seconds @ .71 average G’s vs. 27.6 seconds @ .61 average G’s).

For better maneuverability, the QX30 AWD’s turning circle is 1.4 feet tighter than the XT4’s (36.6 feet vs. 38 feet). The QX30’s turning circle is .7 feet tighter than the XT4’s (37.3 feet vs. 38 feet).

For greater off-road capability the QX30 has a 1.2 inches greater minimum ground clearance than the XT4 (8 vs. 6.8 inches), allowing the QX30 to travel over rougher terrain without being stopped or damaged.

Chassis

The Infiniti QX30 may be more efficient, handle and accelerate better because it weighs about 400 pounds less than the Cadillac XT4.

The QX30 is 6.9 inches shorter than the XT4, making the QX30 easier to handle, maneuver and park in tight spaces.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Cadillac. J.D. Power ranks Infiniti first in service department satisfaction. With a 5% lower rating, Cadillac is ranked third.

Ergonomics

Unlike the driver-only memory system in the XT4 Premium/Sport, the QX30 Luxe/Sport/Essential has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

Heated windshield washer nozzles are standard on the QX30 Sport/Essential to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The XT4 doesn’t offer heated windshield washer nozzles.

The XT4 (except Luxury)’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The QX30 Sport/Essential’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
