Infiniti · Singapore
Infiniti is no longer sold new in Singapore, and when the official showroom closed, owners of the Q50, G37, QX50 and QX80 suddenly had nowhere official to go. We still service them, source the parts, and know these cars well enough to tell you what’s worth fixing and what isn’t.
What Infinitis actually need here
Most Infinitis here are past their tenth year now, with no agent behind them. These are the faults we see most across the VQ37, the VR30 turbo and the Mercedes-engined cars. Knowing which ones are serious, and which can wait, is half the battle once there’s no dealer to ask.
The VQ37’s rear timing cover has two small paper gaskets sealing the oil gallery. On pre-2013 engines these harden and blow out, dropping oil pressure fast. You’ll see a low oil pressure light, a P0524 low-oil-pressure code with P0011 or P0021 following it, and a rattle on startup. Don’t drive on it. A failed gasket can wreck the top end in one short trip, and since the engine has to come apart anyway, it’s the time to do the water pump, chains and tensioners together.
The twin-turbo VR30 that replaced the VQ37 has its own well-known issue: owners report the wastegate actuator area wearing, giving a rattle and eventually limp mode with low boost. Oil sealing around the turbo shafts can also let go, giving blue smoke at idle and oil creeping into the intake. Both turbos tend to wear together, so replacing just one rarely buys much time.
Later Q50s use the Mercedes M274 2.0 turbo rather than a Nissan engine, and the Q30 and QX30 use the transverse M270 on GLA and A-Class underpinnings. Owners report a loss of power under load once warm, and 2016 to 2018 Q50 2.0T cars were recalled over fuel pump control module software that could let the engine stall. Sourcing is the awkward part, because it’s Mercedes hardware in an Infiniti shell, and not every workshop with Infiniti parts will have the right bits on the shelf.
The Q50’s steer-by-wire drives the front wheels electronically, with a clutched backup column that reconnects the steering wheel to the rack if the system fails. A software fault, a weak battery or a failed sensor can throw the wheel and the front tyres out of alignment, or cut the assist entirely. Nissan recalled 2014 to 2016 Q50s because a start-up error in the system could change steering response and turning radius, and the fix was a software reprogram. Diagnosing DAS properly needs the Consult III scan tool, not a generic reader.
Owners bring the QX80 in with a shudder or hesitation from the seven-speed auto at low RPM on light throttle, which you feel most in stop-start traffic. An ECM reset and a fresh transmission fluid service often settles it, though worn internals will bring it back. Across the range, ageing body control and infotainment modules, faded instrument clusters and failing immobiliser antennae are turning up more often now these cars are past ten years with no official support.

Infiniti shares its engineering with Nissan, but the two never shared a showroom here. Under the Q50 and G37 sits the VQ37VHR, an all-aluminium 3.7 V6 with dual VVT that’s widely rated as one of the better engines Nissan ever built. From 2016 the twin-turbo VR30DDTT took over, a different beast with more power and more to look after. The Q50 also earned an odd claim to fame as the world’s first production car to ship with steer-by-wire, which is impressive right up until it needs workshop attention. A footnote enthusiasts enjoy: the G37 Coupe and Convertible were essentially the Japanese-market Skyline V36, with the same VQ37 that powered the 370Z.
Many mechanical parts for the VQ37 cars cross-reference straight to the Nissan 370Z and Skyline V36 part numbers, which helps a lot with availability. The Mercedes M274 cars (Q50 2.0T, Q30, QX30) draw on Mercedes supply instead, so lead times and costs are different. Local dismantlers list used Infiniti parts, and OEM can still be ordered through Nissan’s regional network, though stock on the discontinued models is thinning. We tell you upfront if a part is scarce before we quote.
Set for Singapore driving
The heat, the humidity, and the way we drive (short hops with the aircon flat out from the moment you start) is harder on oil and fluids than the factory schedule assumes. On an ageing Infiniti with no agent behind it, staying ahead of the wear items is what keeps the running cost predictable.
How we quote
It depends on the engine, the model and what the car actually needs. A G37 minor service and a QX80 major aren’t the same job, and a VQ37 with a leaking gallery gasket is a different conversation again, so a flat price would just be a guess. We look at the car, tell you what it needs and what it’ll cost, in writing, before we touch anything.
We won’t tell you we’re the cheapest. What we stand behind is the quality of the work, how we treat you, and taking responsibility when it’s ours to take. The quote is itemised, you get the old parts back, and nothing happens that you didn’t approve.
The orphaned-brand reality
When Infiniti wound down here, owners lost the one place that was meant to look after the car. That’s the gap we fill. We service these to the manufacturer’s schedule, source the parts that are getting harder to find, and keep proper records, so you’re not ringing round every time something needs doing.
There’s no dealer backlog to wait in and no diagnostic fee just to get a quote. We read the faults with the proper tools, including the Consult III scan the Q50’s steering needs, and we tell you the cost before we start. For an out-of-warranty Infiniti, a workshop that already knows the car is worth more than a badge on a building.
The 10-year decision
Around year nine the decision lands on every Singapore owner: put a big sum into renewing the COE, or scrap a car you’ve driven for a decade. It’s one of the most expensive calls you’ll make, and on an Infiniti there’s no agent to give you a straight answer.
With no official dealer and parts for some models already thinning, that call matters more here than on a mainstream brand. A Q50 or G37 in genuinely good order can still justify a five-year renewal, but you need a clear picture of what it’ll need over those five years before you commit. Bring it in and we’ll walk you through what we find, not what gets you to sign.
If it’s fundamentally sound, renewing and running it properly can beat starting again. If it isn’t, we’ll tell you. We don’t sell COEs and we don’t sell new cars, so we’ve no reason to push you either way.
Why owners bring their Infiniti to us
We’ve got the proper diagnostic tools for these cars, including the Consult III scan the Q50’s DAS needs, not a generic reader, so we see what the car is actually saying instead of guessing. We explain it in plain language. And it’s one team for the service, the repair, the insurance and the claim if it ever comes to that, so you’re not bouncing between five numbers for a car the dealers walked away from.
