After 40,000 miles of rigorous testing, Mazda’s flagship three-row SUV, the CX-90 Turbo S, has revealed significant shortcomings that challenge its premium aspirations. What began as a promising entry into the competitive large SUV segment ended with a verdict that surprised many automotive experts: impressive hardware specifications failed to translate into satisfying real-world driving dynamics.<\/p>\n
When Mazda introduced the CX-90 Turbo S, the automotive world took notice. The specifications read like a wish list for performance enthusiasts shopping in the three-row SUV category: a 340-horsepower inline-six turbocharged engine, a sophisticated eight-speed automatic transmission, and Mazda’s signature Kodo design language applied to their largest vehicle yet. The company positioned the CX-90 as the culmination of their “premiumization” strategy, promising driving dynamics that would set it apart from mainstream competitors while offering the practicality families demand.<\/p>\n
On paper, the CX-90 Turbo S seemed positioned to challenge established players like the Audi Q7, BMW X5, and even some domestic offerings. Mazda’s reputation for crafting vehicles with superior driving dynamics to their mainstream competitors created genuine excitement. Early reviews praised the interior quality, distinctive styling, and the novel powertrain configuration. The stage appeared set for Mazda to successfully enter a new segment while maintaining their driver-focused philosophy.<\/p>\n
The first thousand miles with the CX-90 Turbo S suggested Mazda had delivered on their promises. The inline-six engine provided smooth, abundant power. The transmission shifted crisply, and the steering felt precise during initial test drives. The cabin impressed with its upscale materials and thoughtful layout. However, as the miles accumulated, fundamental issues with the driving experience began to surface that weren’t apparent during shorter evaluations.<\/p>\n
By the 10,000-mile mark, test drivers noted a growing disconnect between the vehicle’s impressive specifications and how it actually felt on the road. The suspension, while competent on smooth surfaces, transmitted too many small road imperfections into the cabin. On longer highway trips, the ride quality became fatiguing rather than relaxing\u2014a critical failing for a vehicle likely to be used for family road trips. The noise insulation, while adequate, didn’t match the serene cabins of true luxury competitors.<\/p>\n
The much-touted 3.3-liter turbocharged inline-six engine, while powerful on paper, revealed calibration issues during extended use. The transmission programming seemed uncertain in certain driving conditions, sometimes hesitating between gears or hunting for the right ratio during gradual acceleration. While the engine produced ample power for merging and passing, its delivery lacked the seamless refinement expected in a vehicle with premium aspirations.<\/p>\n
“The powertrain feels like it’s constantly making decisions rather than responding intuitively to driver inputs,” noted one long-term tester. “After 20,000 miles, what initially felt sophisticated began to feel overly complicated and occasionally unrefined.” This disconnect became more pronounced during stop-and-go traffic, where the transmission’s behavior could be unpredictable, and during aggressive driving, where the powertrain response didn’t match the vehicle’s sporting pretensions.<\/p>\n
The CX-90’s greatest challenge emerged in balancing its role as a practical three-row family vehicle with Mazda’s trademark driving dynamics. The suspension tuning attempted to walk a fine line between comfort and sportiness but ultimately satisfied neither objective completely. With all three rows occupied\u2014a realistic scenario for families purchasing this type of vehicle\u2014the handling characteristics changed noticeably, with more body roll and less precise steering feedback than when driving solo.<\/p>\n
During emergency maneuvers or sudden lane changes, the CX-90’s weight distribution and suspension tuning revealed limitations. The vehicle felt less composed than expected given Mazda’s reputation for chassis tuning. While never unsafe, the handling dynamics lacked the confidence-inspiring precision that defines Mazda’s best products. This was particularly disappointing given the vehicle’s sporting appearance and performance-oriented marketing.<\/p>\n
By 30,000 miles, unusual tire wear patterns began to emerge, suggesting potential alignment or suspension geometry issues under long-term use. Front tires showed more wear than expected, while rear tires developed uneven wear patterns that couldn’t be attributed solely to rotation schedules. Brake performance remained adequate throughout the test period, but pedal feel deteriorated slightly over time, developing a less linear response that diminished driving confidence.<\/p>\n
These wear patterns weren’t just maintenance concerns\u2014they reflected deeper issues with how the vehicle managed its substantial weight during everyday driving. The CX-90 Turbo S weighs approximately 5,000 pounds, and this mass seemed to challenge Mazda’s engineering in ways that shorter-term tests couldn’t reveal. The cumulative effect of 40,000 miles of varied driving conditions exposed compromises that might not appear during a week-long press loan.<\/p>\n
The CX-90’s interior initially impressed with its design and materials, but long-term use revealed ergonomic shortcomings. The third-row seats, while adequate for children, proved uncomfortable for adults on anything beyond short trips\u2014a common issue in the segment but one Mazda had suggested they’d addressed. Cargo space behind the third row was limited compared to some competitors, forcing difficult packing decisions on family trips.<\/p>\n
More concerning were the seats themselves. After 25,000 miles, drivers reported decreasing comfort during long journeys, with insufficient lumbar support and cushioning that lost its supportive qualities. The second-row captain’s chairs, while offering individual comfort, created a awkward central walkway that proved less practical for family use than a traditional bench seat might have been.<\/p>\n
Mazda’s infotainment system, while improved over previous iterations, revealed interface frustrations during extended ownership. The combination of touchscreen and rotary controller worked adequately but never felt intuitive for all functions. Several software glitches occurred throughout the 40,000-mile test, including occasional reboots of the system and connectivity issues with smartphones.<\/p>\n
The digital instrument cluster, while visually appealing, sometimes presented information in less-than-ideal layouts during certain driving conditions. Advanced driver assistance systems performed reliably but occasionally provided alerts that felt overly sensitive or intrusive. These weren’t deal-breaking issues individually, but collectively they diminished the premium experience Mazda sought to create.<\/p>\n
When compared directly with established competitors over the same 40,000-mile period, the CX-90’s shortcomings become clearer. Vehicles like the Kia Telluride and Hyundai Palisade, while less sporty in their positioning, offered more consistent ride quality and superior interior packaging. European competitors like the Audi Q7 and BMW X5, while more expensive, delivered the refined driving dynamics and premium feel that the CX-90 promised but couldn’t consistently deliver.<\/p>\n
Perhaps most telling was the comparison with Mazda’s own smaller vehicles. The driving enjoyment and chassis precision that define Mazda’s CX-5 and Mazda3 simply didn’t translate effectively to the larger, heavier CX-90 platform. This suggests that Mazda’s engineering philosophy, so successful in smaller vehicles, faced significant challenges when scaled up to three-row SUV dimensions.<\/p>\n
With a price tag approaching $60,000 for a well-equipped Turbo S model, the CX-90 entered premium territory where expectations are correspondingly higher. Over 40,000 miles, the vehicle’s shortcomings in driving dynamics, ride quality, and long-term refinement became difficult to justify at this price point. While the CX-90 offered more standard features than some competitors, the core driving experience didn’t match the premium pricing.<\/p>\n
This creates a challenging value proposition: buyers seeking genuine luxury refinement would likely look to established premium brands, while those prioritizing practicality might choose less expensive alternatives that offer similar or better comfort and space. The CX-90 Turbo S found itself in a difficult middle ground\u2014too expensive to compete purely on value, yet not refined enough to compete purely on driving experience.<\/p>\n
Throughout the 40,000-mile test, several minor quality issues emerged that raised questions about long-term durability. Interior trim pieces developed slight rattles, particularly around the dashboard and center console. The power liftgate occasionally hesitated or required multiple attempts to open completely. While no major mechanical failures occurred, these small issues suggested potential quality control challenges as Mazda ramped up production of their most complex vehicle to date.<\/p>\n
The paint quality and exterior finish held up well to various weather conditions and highway driving, maintaining their appearance with proper care. However, several panel gaps showed slight inconsistencies that weren’t noticeable at delivery but became apparent under close inspection after months of use. These weren’t major defects, but they contributed to an overall impression that didn’t quite match the premium standards Mazda aimed to achieve.<\/p>\n
The CX-90 Turbo S’s performance over 40,000 miles offers important lessons for Mazda’s ongoing premiumization strategy. Creating a truly premium vehicle requires more than upscale materials and powerful specifications\u2014it demands cohesive engineering where all systems work together seamlessly over the long term. The CX-90’s individual components were often impressive, but their integration revealed shortcomings that affected the overall ownership experience.<\/p>\n
Mazda faces the challenge of scaling their driver-focused philosophy to larger vehicles without compromising the qualities that make their smaller vehicles so engaging. The CX-90 experience suggests this translation isn’t straightforward and may require different engineering approaches than those used in Mazda’s traditional segments. Future iterations will need to address the fundamental balance between comfort and sportiness that proved elusive in this initial offering.<\/p>\n
The CX-90’s mixed performance raises questions about how Mazda will approach other large vehicles in their planned lineup expansion. If the company’s engineering strengths don’t scale effectively to three-row dimensions, they may need to reconsider their approach to the large vehicle segment or accept that they’ll compete on different terms than in their core segments. This doesn’t mean abandoning premium aspirations, but rather redefining what “premium” means in larger vehicle categories.<\/p>\n
Alternatively, Mazda might double down on their strengths in smaller segments while accepting a different role in the large SUV market. The automotive landscape continues to evolve rapidly, with electrification and changing consumer preferences creating new opportunities. How Mazda responds to the lessons learned from the CX-90’s 40,000-mile test will shape their product strategy for years to come.<\/p>\n
For consumers considering the Mazda CX-90 Turbo S, the long-term test reveals a vehicle that promises more than it delivers. While offering attractive styling, a powerful engine, and an upscale interior, its driving dynamics fail to meet the standards set by Mazda’s reputation and the vehicle’s own specifications. In the competitive three-row SUV market, where refinement and long-term satisfaction are crucial, these shortcomings matter. The CX-90 represents an ambitious step for Mazda, but one that reveals how difficult true premium execution can be\u2014especially when measured not in test drives, but in the accumulated experience of 40,000 miles of real-world use.<\/p>\n","protected":false},"excerpt":{"rendered":"
