Select a Infiniti Model
Infiniti Q60
The Infiniti Q60 is a stunningly beautiful luxury coupe that replaced the G37, offering head-turning design and a grand touring driving experience. Competing against the Audi A5 and BMW 4 Series, it prioritized long-distance refinement and comfort over sharp, track-focused handling. In the UK, it was available with a 2.0-litre turbocharged four-cylinder or a potent 3.0-litre twin-turbo V6 (Red Sport), the latter offering serious straight-line speed. Due to the brand's withdrawal from the UK market, these cars suffer from steep depreciation, making them incredible used bargains. It suits buyers who prioritize striking aesthetics, smooth power, and exclusivity over razor-sharp handling.
Infiniti Q30 / QX30
The Q30 and its crossover sibling, the QX30, were Infiniti's attempt at premium compact cars, heavily based on the Mercedes-Benz A-Class and GLA. They share platforms, engines, and gearboxes with Mercedes, meaning they inherit both German refinement and specific mechanical weaknesses.
Infiniti Q50
The Infiniti Q50 is a sleek, handsome executive saloon that was Nissan’s luxury division's attempt to challenge the BMW 3 Series and Mercedes C-Class. It offered a high level of standard equipment, a comfortable ride, and uniquely aggressive Japanese styling. In the UK, it struggled to gain a foothold due to the dominance of German brands, making it a rare and depreciated used buy. The most controversial feature was the "Direct Adaptive Steering" (steer-by-wire system) on certain models, which felt artificial to driving enthusiasts. Reliability is generally robust, especially the Mercedes-sourced 2.2-litre diesel, making it a left-field bargain for buyers wanting a distinctive, reliable executive cruiser.
Infiniti QX70 (FX)
Formerly known as the FX, the Infiniti QX70 is a striking, aggressive-looking luxury SUV that prioritized sporty handling and swooping design over outright practicality. It drove more like a tall sports car than a traditional SUV, offering a firm ride and potent V6 engines, including a raucous 3.7-litre petrol and a muscular 3.0-litre diesel. In the UK, its bold styling and massive 21-inch wheels gave it immense road presence, though its heavy fuel consumption limited its appeal. Reliability is excellent, underpinned by proven Nissan mechanicals. It is best suited for buyers who want an imposing, sporty, and reliable SUV, and are willing to accept high running costs and a relatively small boot.
About Infiniti Reliability
Common Infiniti trouble spots
- •The InTouch dual-screen infotainment system is known for being slow to boot, prone to freezing, and having limited smartphone connectivity on older models.
- •Models sharing Mercedes-Benz components (Q30, QX30, Q50 2.2d) inherit specific issues like timing chain tensioner failures and DCT gearbox sensor glitches.
- •The innovative Direct Adaptive Steering (DAS) on early Q50 models can feel "numb" or suffer from software glitches that require dealer-only recalibration.
- •Parts for bodywork and unique interior trim can be extremely expensive and difficult to source following the brand's withdrawal from the UK.
What to check on used Infinitis
- ✓Confirm where your nearest servicing centre is. While some Nissan dealers still support Infiniti, dedicated specialist knowledge is becoming rarer.
- ✓Be aware that parts lead times can be significantly longer than for mainstream brands, as many components are shipped from Japan or central European hubs.
- ✓Infiniti cars often feature very high standard specifications; ensure all electronic features, especially the dual-screen InTouch system, work correctly as repairs are costly.
- ✓Check for a full service history. Given the brand's niche status in the UK, a lack of specialist maintenance can lead to overlooked issues with complex systems like DAS steering.
