Infiniti Specialists in Dubai
VQ & VR Engines · Jatco CVT · Q50 · Q60 · QX60 · QX80
Infiniti has established a strong and loyal ownership base in Dubai since the brand's introduction to the UAE market. As the luxury arm of the Nissan-Renault-Mitsubishi Alliance, Infiniti vehicles offer a compelling proposition: the proven mechanical foundations of Nissan's best engineering, wrapped in premium interior quality, advanced driver assistance technologies and bold styling that differentiates them from the ubiquitous German luxury brands that dominate Dubai's premium car market.
The Q50 saloon is the most widely driven Infiniti in the UAE, available with the 2.0-litre turbocharged four-cylinder or the naturally-aspirated 3.7-litre VQ37VHR V6. The Q60 coupe uses the same drivetrain in a more overtly sporting body, while the QX50 crossover — now powered by Infiniti's variable compression ratio VC-Turbo engine — represents a significant technical achievement. The QX60 three-row SUV and the flagship QX80 full-size SUV complete a range that covers the most popular segments in the Dubai premium market.
What distinguishes servicing an Infiniti from servicing a mainstream Nissan is the combination of more sophisticated electronics, tighter tolerances, and the premium expectation of the ownership experience. The Q50 and Q60 feature Infiniti's Direct Adaptive Steering system — a steer-by-wire arrangement with no mechanical connection between the steering column and the rack in certain configurations — along with a comprehensive suite of DAS and safety systems managed by multiple ECUs. When warning lights illuminate or fault codes are stored, reading them accurately requires diagnostic equipment with full Infiniti/Nissan protocol access rather than a generic OBD reader. FixHive has invested in professional-grade diagnostic tools that cover the complete Infiniti range.
The VQ engine family — particularly the VQ37VHR 3.7-litre V6 used in the Q60, QX80 and earlier Q50 — is widely regarded as one of the finest naturally-aspirated V6 engines ever produced. It produces its rated output reliably and responds beautifully to precise maintenance. However, it does have a known oil consumption characteristic that owners must be aware of in Dubai: under sustained high-load driving in extreme heat, the VQ37VHR can consume up to 1 litre of oil per 1,500 km, which Nissan and Infiniti acknowledge as within acceptable factory tolerance. In practice this means checking the oil level between services is not optional — it is essential. An Infiniti QX80 driven hard in 45°C heat can go from a full sump to a critically low level between scheduled services if the owner does not monitor it.
At FixHive we service the complete Infiniti range with the same diagnostic depth and parts quality you would expect from a franchised dealer, but with the responsiveness, transparency and pricing of a specialist independent. Whether your Infiniti needs a routine oil service, a CVT fluid replacement, an AC deep clean, or an intermittent fault traced through the DAS electronics, our team is equipped to handle it professionally at our Dubai Investment Park workshop.
Common Infiniti Issues in Dubai
⚠️ VQ37VHR Engine Oil Consumption (Q60, QX80)
The VQ37VHR naturally-aspirated V6 engine used in the Infiniti Q60, QX80 and certain Q50 variants is in many respects an exceptional unit — smooth, powerful, and extremely well-engineered. However, it has a documented tendency to consume engine oil at a rate that surprises owners who are accustomed to modern engines that use very little oil between changes. Nissan and Infiniti consider consumption of up to 1 litre per 1,500 km to be within factory specification for this engine. In Dubai's climate, where the engine operates at higher sustained temperatures and the VQ37 is frequently pushed hard on Sheikh Zayed Road or the Emirates Road at motorway speeds in 45°C+ ambient temperatures, consumption tends to sit at the upper end of this range. The danger for uninformed owners is allowing the oil level to drop below the minimum mark on the dipstick, at which point oil pressure delivery to the variable valve timing solenoids becomes compromised, and bearing lubrication is reduced. This can lead to premature camshaft and bearing wear. FixHive advises all VQ37-equipped Infiniti owners to check their oil level every 2,000 km and maintain a spare litre of the correct specification synthetic oil in the car at all times.
⚠️ CVT Transmission Wear (QX50, Q50 with CVT)
The QX50 and certain Q50 variants use a Jatco-supplied continuously variable transmission. Jatco is the world's largest CVT manufacturer and supplies transmissions to a wide range of Nissan, Infiniti, Mitsubishi and Suzuki vehicles. The CVT is a refined and efficient unit under normal conditions, but it has a specific vulnerability to heat-degraded fluid — a problem that is significantly amplified in Dubai's climate. CVT fluid serves as both a hydraulic medium for the belt-and-pulley pressure system and a lubricant for the chain, bearings and pump. When it degrades — which occurs faster above 40°C ambient in stop-start city traffic — the fluid loses viscosity and its anti-wear additives deplete. Symptoms include a shudder or vibration felt through the floor when pulling away from a standstill, a hesitation when the transmission transitions between drive ratios during acceleration, and occasionally an overheating warning on the dashboard instrument cluster during extended urban driving. Left unaddressed, worn CVT fluid causes accelerated belt and pulley wear that ultimately requires a costly transmission overhaul or replacement. FixHive recommends CVT fluid replacement every 40,000 km on Jatco-equipped Infinitis in UAE conditions, using only the specified NS-3 or NS-2 type CVT fluid.
⚠️ Electronic Throttle & ECM Faults (Q50 / Q60)
The Infiniti Q50 and Q60 feature a highly sophisticated electronic throttle control and engine management system that, while highly refined in normal operation, can develop fault codes that manifest in ways that confuse owners and even generic workshops. The most common presentation is an illuminated check engine or VDC warning light accompanied by a noticeable reduction in throttle response — colloquially referred to as "limp mode." Stored DTC codes in this scenario often relate to the throttle position sensor, the accelerator pedal position sensor, or in some cases a fault within the ECM (Engine Control Module) itself. The Q50's by-wire throttle system has no direct mechanical linkage between the accelerator pedal and the throttle body, meaning any signal disruption — from a faulty sensor, a poor ground connection, or a software issue — immediately affects drivability. Diagnosing these faults accurately requires an Infiniti-compatible scanner that can access and display live PID data from the relevant control modules, not just generic OBD fault codes. At FixHive we carry professional Infiniti diagnostic equipment and have experience with the full range of Q50 and Q60 electronic fault presentations, from simple sensor replacements to ECM reprogramming requirements.
⚠️ AC Evaporator Failures & Cooling Performance (QX60 / QX80)
The Infiniti QX60 and QX80 both feature dual-zone climate control systems with front and rear evaporator cores — a configuration that delivers excellent cabin comfort but also doubles the number of refrigerant circuit components that can develop leaks over time. Evaporator core micro-leaks are a common cause of AC system underperformance that is difficult to detect without specific tools. The evaporator sits behind the dashboard and exchanges heat between the cabin air and the refrigerant, and because it operates in a continuously humid environment — condensation forms naturally on the cold evaporator surface — any micro-crack or joint failure allows refrigerant to seep out very slowly. The first sign is usually a musty or slightly sweet smell from the vents when the AC is first switched on, caused by refrigerant oil deposits on the evaporator surface collecting dust and bacteria. As the leak progresses, cooling performance declines gradually, and eventually the system loses enough refrigerant to trigger a low-pressure cutout. In Dubai's summer heat, a partially functional AC system in a QX60 or QX80 is not merely uncomfortable — it is a safety concern for passengers. FixHive performs a full leak detection check and refrigerant charge verification on every Infiniti AC service, using UV dye and electronic leak detection equipment to locate evaporator leaks before they cause complete system failure.
