How To Change Infiniti Q50 Engine Air Filter
By the time it neared the 10,000-mile marking, our long-term Infiniti Q50S hybrid's reputation for erratic behavior was fix in stone. Although the machine was praised on arrival for its sculpted bodywork, Venetian Cerise paint, and comfy seating, further attempts to course a loving bond with our Q50S were rebuffed at nigh every turn.
"The steering is baroque," said one early on commenter, setting a precedent for things to come. Another cited a spongy brake pedal and its synthetic feel and "on/off switch" response. So universal was the dislike for the steering and braking dynamics that logbook entries often declared them not yet ready for prime time. Specifically, the fully electric, by-wire Straight Adaptive Steering (DAS) came under burn for being completely devoid of feedback and feel and as well for being "absurdly quick," even on the Standard setting. The brakes, on the other mitt, were grabby, with a hard transition from regenerative mode to friction braking under hard deceleration, making information technology nearly impossible to modulate them with any subtlety. As enthusiasts, we knew many of the elements required to make a decent chassis were in place, so the Q50S's overanxious steering and braking behavior had united states specially miffed. A reflash of the steering software effectually the xv,000-mile mark failed to tame its harsh and unpredictable reactions.
While these characteristics prevented our human relationship with the Q50S hybrid from blossoming, we did observe a few bright spots that made living with its dynamic neurosis a little more tolerable. Long-altitude travelers noted its appetite for devouring long, straight stretches of interstate in drama-complimentary fashion, the feel enriched by its comfy seats and fabulous-sounding audio system. Most were in agreement that the all-bicycle-drive system operated seamlessly and that the four.nine-second zero-to-60-mph time (as tested at the 40K mark) provided past its combined 360-hp hybrid powertrain was more than sufficient. The hybrid system got some good marks for its power to shuffle betwixt gas and electric propulsion modes, but certain situations, such every bit long, low-speed downhill sections, could crusade information technology to temporarily second-gauge itself before settling in.
In addition, manipulating the multifunction infotainment organisation with finesse required a steep learning bend, many cursing its nearly pathological penchant for reverting to the map screen moments after any input. But as most staffers were getting wise to the vagaries of the system, it added a new trick that we reported to the dealer at its thirty,000-mile service: refusing to advance by the main-menu screen regardless of user input. As mentioned in a previous update, the dealer diagnosed information technology as a defective Dashboard Control Unit of measurement (DCU) and ordered a replacement for installation at a later date. The 30K service (oil modify, rear-differential fluid change, air- and cabin-filter replacements, tire rotation, and inspections) was a pricey one, costing a absurd $668.77: $328.39 for the parts, $289.95 for labor, $29 for shop fees, and $21.43 for tax. When the new DCU arrived, nosotros returned to the dealer for installation, which included an update of the software.
Infotainment functionality restored, the Q50S embarked on the 250-mile expedition to the 2015 Chicago automobile prove in February, an excursion that, as it happened, gave the car a hazard to display its superb foul-atmospheric condition capabilities. While the outbound trip proved uneventful, the return trip placed the car and its driver in the heart of a colossal lake-effect snowstorm. With winds blowing off Lake Michigan creating massive snowdrifts and whiteout weather across I-94, the Q50S's all-bicycle drive and Bridgestone Blizzaks dug in hard, maintaining secure grip and forward progress while many cars around us broke costless and spun into the median. When traffic came to a halt for nearly three hours due to a multivehicle, bidirectional pileup, the Q50S hybrid'south interior and heated seats kept united states toasty warm on electric energy from the batteries lone, the gasoline engine remaining off for forty minutes at a time.
Dorsum at C/D HQ, a quick look at the odometer revealed the Q50S hybrid had accumulated approximately 33,500 miles nether our watch and its days here in Ann Arbor were numbered. In mid-February, we dispatched the Q50S hybrid to the dealer for its 35K service, which included an oil alter, tire rotation, and inspections for $89.06. Convinced that winter had dealt its terminal blow, in Apr nosotros swapped out our hibernate-saving Blizzaks for summertime safe in our own garage. Soon after, we noticed a vibration nether hard braking, necessitating a trip to the dealership to have the front end brake rotors resurfaced. During the same visit, the dealer performed the 40K service (oil change, tire rotation, and inspections) and charged united states a full of $337.39: $88.79 for the scheduled service and $248.60 for the rotor resurfacing.
With a base of operations MSRP of $49,405 and an as-tested price of $51,035—the only options on our car were the $1400 navigation parcel and $230 for an all-flavour trunk liner and floor mats—our long-termer was chock-full of features and content that would send the price of some European imports into the stratosphere. Sunroof? Standard. LED headlamps? Standard. Eight-style ability-adjustable heated seats with adjustable lumbar and trunk supports? Standard. And the listing goes on. Despite the added complexity these niceties can sometimes innovate, our Q50S hybrid AWD was a paragon of reliability. Information technology never stranded u.s.a. one time, and the service cost total of $1685 reflects merely scheduled maintenance. The aforementioned Dashboard Control Unit was covered under Infiniti's iv-yr/60,000-mile bumper-to-bumper warranty.
Ultimately, no amount of content, good looks, or comfortable seating tin can overcome the sins committed by the steering and the brakes. Ane logbook commenter summed up the Q50S quite succinctly: "A decent car hamstrung with electronic gizmos."

WHAT WE LIKE: After spending the summer in the wilds of Montana, our long-term Infiniti Q50S returned to Ann Arbor simply as the leaves began to turn. With xxx,390 miles on the odo, the car has reached the 3-quarter mark of its stay, and niggling has happened to alter our initial perceptions of Infiniti'southward loftier-tech hybrid. Fuel economy remains unchanged at a combined 27 mpg, although online editor Alex Stoklosa recorded an impressive 32 mpg during a 2600-mile trip. The seamless shuffling among gas, EV, and hybrid modes at highway speeds has garnered a few compliments, and the heated, multiadjustable front seats continue to win rave reviews from drivers knocking out megamile days.
WHAT Nosotros DON'T LIKE: At that place's no way around it—the brake pedal in the Q50S is a schizophrenic brute, alternately soft and lazy or hard and reactionary. This logbook annotate says it all: "I've driven the Q50S for a week and a half at present and the brake response is impossible to predict. It's more than than annoying; it's scary sometimes." There's no honey lost for the electric drive-by-wire steering, either, even afterward its software was reflashed around the 15,000-mile mark. Although these bug are owned to the Q50S hybrid and accept been noted since its arrival, they continue to dominate the logbook. Newer demerits revolve around a high level of tire noise, harsh impacts over expansion joints, and the fact that the navigation system won't have inputs while underway. This is no mistake of the car, but when we swapped the summer condom for the wintertime set in October, the amount of tire noise increased and made the steering feel fifty-fifty more nervous.
WHAT WENT Incorrect: Although nosotros weren't aware of whatsoever pressing needs at the time, Infiniti treated our Q50S to a few software flashes free of charge at the 25,000-mile service. This included a power-inverter update, an unspecified ECM reprogram, and an infotainment update that added Facebook and Google search adequacy. Subsequently, somewhere curt of the 30,000-mile mark, drivers started reporting erratic beliefs from the infotainment system, and information technology ultimately became stuck on the startup/home screen. The dealer determined that the DCU (Dashboard Control Unit) was at mistake and ordered a new 1 to exist installed at a afterwards date. And at some indicate just before the car's 30K service, a mysterious silver-dollar-sized scratch/dent appeared on the left-rear quarter-console. No one has fessed up to or discovered when, where, and how the damage occurred, just the repair set us back a cool $977.
WHERE WE WENT: In add-on to the marathon run John Phillips made from Montana to Ann Arbor, several other staffers racked up thousand-mile-plus journeys in our Q50S. It hit Charleston, South Carolina; Chicago; Nashville; and many points in between, and it also made a trip to Boston over Thanksgiving. Despite the dynamic complaints, driver after driver commented on how splendid and comfortable the motorcar was on the highway and when pointed in a direct line. We haven't experienced wintertime's foul temper notwithstanding this flavor, but the AWD Q50S proved to be a capable foul-conditions performer terminal year, and we wait to finish off this test in brusk order no thing what the clouds outset dropping on us.

WHAT We Similar: For the nine months and 23,022 miles we've lived with our "Venetian Ruddy" Q50S, its murderously scowling face and muscled haunches have daily suggested it'south a boulevard brawler rather than a happy-smiley hybrid. In fact, its V-vi and electric motor conspire to produce 360 hp, enough to obtain 60 mph in 5 seconds apartment—non bad for any 4161-pound object—and the accelerative fun continues to 148 mph. What's more than, the 19-inch Dunlops and an apparently well-sorted suspension helped summon 0.85 g on our skidpad. Fair enough for a luxo-sedan with eco-lefty leanings.
The eight-fashion power front seats—with dazzling lumbar support—are orthopedic dreams-come-true for 12 hours at a crack. And the xiv-speaker Bose stereo would brighten whatsoever professional person musician's day.
Our Q50S is an endurance gnaw on interstate slogs, with a useful sense of straight-ahead and a 480-mile range, enough to satisfy astronauts wearing senior undergarments. Correct at present, we're seeing an average of 27 mpg.
Around town, the transition from EV to IC and back goes largely unnoticed, except when the electric motor is nether a light load—in a downhill stretch, for instance—and sudden throttle is required. That's when the V-6 suddenly alights, its ignition mildly juddering through the platform. Plus, we may equally well mention the cute ding-dong chime that sounds outside the car during fill-in maneuvers, like a wakey-wakey call for a daycare plant nursery.
WHAT WE DON'T Like: The Q50S'due south drive-by-wire steering (standard on the hybrid but avoidable on other versions) tracks well but is too quick off-center, feels as bogus as plastic flowers, and transmits minimal road feel—"cached by layers of electrons," equally one of u.s. wrote. Of course, if it'due south the road you want to feel, the Dunlop run-flats oblige—every pebble, frost boost, and route dimple. Then there'south an aural festival of blast, hiss, slap, and snarl that sometimes spoils the Q50S's otherwise serene cockpit. And just wait until those front tires catch an expansion strip simultaneously. Gear up to call your dentist.
Only this Infiniti's most jarring drawback is its restriction pedal, which feels either as squishy as an oatmeal sandwich or as hard and grabby as a prison baby-sit. In that location is no in-between. Neither can you predict which direction the brakes are leaning. This can get somewhat intense when, say, you've got the automobile pitched far into a turn and all of a sudden request a fiddling whoa. If the brakes grab right then, it upsets the chassis, not to mention the driver, both in a nasty fashion. And it's not a matter of "just getting used to it," because one commuter had the car for v months and still couldn't predict decelerative outcomes. Really, we're too far into the hybrid era for regenerative brakes to feel like this.
Then there'southward the Q50S's $51,035 as-tested toll, which feels a little similar piling on.
Dorsum when Jackie Stewart test-drove all of Ford'southward road cars, he said, "No car gets my approving unless—from the moment I slide behind the wheel—it can be driven smoothly." For years, the guys at Infiniti had Sebastian Vettel. Perchance they should accept had Sir Jackie.
WHAT WENT Incorrect: On four or v occasions, a quick shift from bulldoze to opposite briefly and mysteriously disabled all of the steering'due south power assistance. Happily, that quirk ambled off into the dusk afterward the 15K service. Sometimes the steering-bicycle heater clicked on unbidden into full sweaty-palms manner, non a big problem except for the digital maze required to brand it go away.
We laid out $754.23 for iv scheduled services at 5000-mile intervals. The fifteen,000-mile stop included reprogramming and recalibrating the Direct Adaptive Steering, plus an update to improve observe an adult in the passenger seat—two fixes your father never contemplated in his entire life.
WHERE WE WENT: And so far, the Q50S'south grandest outing has been a multi-month sojourn at our Montana Desk-bound in the Bitterroot Mountains. There, the car daily navigated a kind of Camel Trophy transit section to John Phillips's mountainside driveway, a fair exam of its AWD system. While out West, this sedan served competently every bit an run a risk grand tourer, happening upon a black wolf, a bull moose (whom the locals named Walter Sobchak, from the grapheme in The Large Lebowski), bighorn sheep, elk, mount goats, two behave cubs, and a sow deport who examined the correct-forepart Dunlop every bit if she worked at Tire Rack.
During a sleet storm, the car further completed a to-and-fro of Glacier National Park's "Going-to-the-Dominicus Road." Phillips unwisely set up out with a quarter tank of fuel but achieved salvation when the Q50S happily glissaded the 25-mile downhill segment exclusively on E-juice and in near-full silence. That journey involved four adults (five won't really fit), all of whom praised the seats only not the trunk, where their minimal luggage—four Barbie-size duffels and two cameras—had to be rudely compacted because the battery pack pares trunk chapters to a miserly nine.4 cubic anxiety.

The first new model to debut under Infiniti's reshuffled alphanumeric nomenclature scheme, the 2014 Q50 takes the spot formerly held by the G37 sedan. Every bit Infiniti's torchbearer in the competitive entry-luxury sport sedan segment, the Q50 was tasked with covering a lot of product bandwidth for the make. Thus, when the revamped Q50 hit the footing at the 2013 Detroit machine show, it brought with it the announcement that a hybrid version would be bachelor for 2014. Our interest was piqued–eco-posturing aside, what driver benefits would a hybrid Q50 offer that weren't already nowadays in the nonhybrid version? To draw our own conclusions, we ordered a 2014 Infiniti Q50S Hybrid AWD in a deep shade of Venetian Carmine for a proper forty,000-mile evaluation.
The Q50s Hybrid AWD arrived at our Ann Arbor offices wearing the same fresh sheetmetal, interior features, and pair of sinister-looking front headlamp binnacles that adorn all Q50 trim levels. The differences begin with the powertrain: In add-on to picking up a 67-hp electric motor and its attendant 1.4-kWh battery pack, the hybrid version employs a 302-horse 3.five-liter V-6 in identify of the nonhybrid's 328-hp iii.7-liter V-6. Combined, the hybrid system is rated at 360 horsepower, a 32-pony increment over the standard car. Shared outright are the 7-speed automatic transmission and Infiniti'southward controversial Straight Adaptive Steering system (more than on that later).
All the Toys
Taking the fundamental fob to a Q50S Hybrid AWD grants one access to a pretty comprehensive assortment of standard features, including Infiniti's slick InTuition arrangement, which permits the storing of preferred climate, sound, and driving settings on said key fob, eliminating the need to reset them manually each fourth dimension ane enters the motorcar—ideal for two-driver households. Boosted standard niceties fitted to our Q50's graphite-colored interior include a power moonroof, eight-way power heated leather front seats with manually adjustable thigh supports, dual-zone automatic climate control, and a heated, leather-wrapped steering wheel on a power-adjustable tilt and telescopic column. At the corners reside 19-inch aluminum wheels with 245/40 Dunlop 5000 SP Sport DSST CTT run-flat tires.
The optional equipment on our test car was limited to the Navigation bundle ($1400), which brings vox recognition, SiruisXM Traffic, and 12 months of the proprietary Infiniti Connection telematics organisation, as well equally the All Weather condition Package ($230), which adds four floor mats and a trunk protector. Including destination, the Q50S Hybrid's MSRP crept to an as-tested price of $51,035, close to the stickers of luxury-branded competitors such as the BMW ActiveHybrid 3 and the Acura RLX Sport Hybrid SH-AWD.
Strapping our test gear to the machine revealed some encouraging numbers: The zero-to-sixty-mph sprint clocked in at 5.0 seconds and the quarter-mile at 13.7, bettering the numbers of the rear-wheel-bulldoze 2014 Q50S Hybrid we tested previously by 0.one second in both measures. Interestingly, it was just mere tenths behind the 4.9- and 13.five-second marks set by a nonhybrid rear-bike-drive 2014 Q50 also tested. Digging a little deeper, we establish that the acceleration numbers matched those of the 2013 BMW ActiveHybrid iii in the zip-to-60 run and gave up only 0.2 seconds in the quarter-mile. Hauling the 4161-pound Q50 to a stop from seventy mph required 174 feet, a shorter span than required by either of the same hybrids. The Q50 Hybrid did, however, suffer from heavy fade.
Touchy, Feely
Unfortunately, those respectable performance numbers don't translate to a tactile feel at the captain, particularly in the areas of braking and steering. Despite an update early in the model run to address bulldoze-quality deficiencies, the Q50 Hybrid's logbook is littered with criticisms directed at the car's fully electric, drive-by-wire Directly Adaptive Steering (DAS), i editor going equally far every bit saying that "playing Gran Turismo on a dual-shock controller offers more feedback and feels more than natural." Specifically, the bulk of the complaints focus on the steering'due south "freaky" quick nature, coupled with zero feedback and the need to make about constant corrections. The brakes likewise inspired some colorful commentary, centering on a grabby initial pedal response followed by a general lack of linearity. 1 editor summed information technology up nicely by stating, "they are impossible to modulate smoothly."
Still, the Q50 managed to whorl up considerable miles in its first few months hither. Early in its stay, we swapped the all-season Dunlops for Bridgestone winter safe, which combined with the Q50'due south AWD drivetrain to brand the auto double as a snow machine during the long harsh winter. To this bespeak, Virginia is the farthest from home that the Infiniti has traveled. And so far, it has yielded an overall fuel efficiency of 25 mpg, a disappointing 2 mpg below the EPA metropolis rating. Ane particularly relaxed-pace excursion into the apartment expanses of Ohio generated a best-yet number of thirty mpg, proving that the Q50 Hybrid is capable of achieving its EPA highway rating of 31 mpg when driven in accordance with country traffic laws.
Just later on the snow receded here in Michigan, we sent the Q50 Hybrid westward for a stint with our Montana bureau editor John Phillips. We're sure he'll have no shortage of words and insights when it comes fourth dimension for the Q50's first long-term exam update. —Andrew Wendler
