Known Subaru Stella faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01i-CVT low-speed shudder and ageing-fluid wear (inferred from Subaru CVT pattern)
MajorCommonTransmission $200–$4,500 to fix
Most Stellas were sold with Subaru's i-CVT continuously variable transmission (the supercharged grade using the 7-speed sportshift version shared with the R2). Across Subaru's CVT range the most common complaint is a low-speed shudder or judder felt on gentle take-off and light throttle, generally traced to CVT fluid that has aged and lost its friction additives rather than a hard mechanical failure; a fresh fluid change often clears it if caught early. On a light kei car with an unknown fluid history the small transmission works hard, and a unit that has been driven while shuddering can wear internally and become expensive because replacement relies on scarce used kei CVTs. This entry is inferred from the general Subaru CVT pattern rather than confirmed Stella-specific failure reports, so it is seeded for buyer awareness; the practical safeguard is a careful cold-and-warm test drive and checking the CVT fluid history.
Symptoms to notice
Shudder or judder felt through the car pulling away from a stop
Vibration or hesitation under light throttle at low speed
Delayed or jerky pick-up when moving off
Symptom eases after a fluid change then returns if the unit is worn
What to check
Test-drive from cold and again once warm, pulling away gently from several standing starts on a flat road, and feel for shudder through the seat and floor at low speed. Ask when the CVT fluid was last changed and whether the correct Subaru fluid was used; a car with no fluid record or an audible judder should be inspected by a transmission specialist and priced cautiously, since a worn kei CVT is costly to replace relative to the car's value.
Where to look: i-CVT transaxle and its fluid, driving the front (or all four) wheels
Ask the seller
“When was the CVT fluid last changed and was the correct fluid used?”
“Do you feel any shudder or vibration pulling away from a stop?”
“Has the transmission ever been serviced, repaired or replaced?”
“Is there any transmission service history from Japan or since import?”
02Rear Torsion Beam Axle Bush Collapse
MinorCommonSuspension $200–$500 to fix
Rear beam axle bushes harden and collapse causing handling noise and imprecision.
Symptoms to notice
Knocking from rear suspension over rough surfaces
Imprecise rear handling feel
What to check
Inspect rear beam mounting bushes for cracking. Push beam laterally with vehicle raised — any movement indicates worn bushes.
Where to look: Rear beam axle mounting points
Ask the seller
“Has the rear torsion beam axle been inspected or repaired?”

Like any used car, it depends on the specific example and its service history. Across the 10 documented faults for the Subaru Stella, the recurring problem areas are transmission, engine, and electrical. A Subaru Stella with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.

We've catalogued 10 known faults for the Subaru Stella, covering transmission, engine, and electrical. Two are written out in full on this page. The rest — with the symptoms to notice, what to inspect, and typical repair costs for each — are free once you create an account.
How much do repairs cost on a Subaru Stella?
+
Most single repairs on the Subaru Stella fall between $250–$1,800 at NZ independent-workshop rates. Some of the 10 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Subaru Stella?
+
Yes. A Subaru Stella inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
