Known Lexus RC faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01Fuel tank vent recall — fire risk
CriticalOccasionalFluid Leaks $0–$2,000 to fix
Lexus recalled IS, RC and GS models built between 2012 and 2018 over a fault in the fuel tank vent that carries a fire risk. A vent that does not work as intended allows fuel vapour or fuel itself to escape where it should not, and fuel vapour around a hot exhaust is the reason this is treated as a safety recall rather than an emissions one. There is very little a driver would reliably notice beforehand, which makes it a VIN check rather than an inspection. It is worth asking about specifically on an imported car, because the original recall notice went to an owner overseas and a New Zealand owner may genuinely never have been told the campaign existed.
Symptoms to notice
Smell of fuel around or under the car, particularly after filling
Difficulty filling the tank, or the pump clicking off repeatedly
Hissing or an unusual rush of air when the filler cap is opened
Engine warning light with evaporative emissions codes
Often nothing at all — the fault gives little warning
What to check
Take the VIN from the base of the windscreen or the driver's door jamb and ask a Lexus dealer which campaigns are outstanding on this specific car, asking about the fuel tank vent recall by name. The check is free and it is the only reliable answer, because nothing on the car will tell you. Ask the seller for recall letters or dealer invoices and read them rather than accepting a summary, and ask whether the car was imported and whether it has been to a Lexus dealer in New Zealand. Then use your nose, which is the most sensitive thing you have here: walk around the rear of the car before the drive and again afterwards, checking for any smell of fuel. Open the filler and listen for an unusual hiss or rush of air. Ask whether the car is ever awkward to fill or whether the pump clicks off early, which is the symptom owners most often notice. Watch the dash for an engine warning light. If a workshop inspection is possible: ask for stored evaporative-system faults to be read alongside the recall check.
Where to look: Underneath the rear of the car — fuel tank and its vent system
Ask the seller
“Has the fuel tank vent recall been completed, and is there a dealer invoice?”
“Was the car imported, and has it been to a Lexus dealer here?”
“Is it ever awkward to fill, or does the pump click off early?”
02RC350 8-speed auto jerky low-speed shifting
MinorOccasionalTransmission $250–$2,000 to fix
The RC350's 8-speed automatic can shift jerkily or hesitate at low speed, particularly the 1-2 and 2-3 shifts in traffic, an often-noted trait that can be improved with fluid service or software but should be assessed on a test drive.
Symptoms to notice
Jerky low-speed shifts
Hesitation before downshifts
Clunk in stop-start traffic
Flare between gears
What to check
Test drive in traffic assessing low-speed shift quality, check fluid service history, and scan for transmission codes.
Where to look: 8-speed automatic transmission
Ask the seller
“Any jerky or harsh low-speed shifts?”
“Has the transmission fluid been serviced?”
“Any transmission software updates?”
