Toyota Raize: 1KR-VET Intercooler Charge Pipe Clamp Loosening

1KR-VET Intercooler Charge Pipe Clamp Loosening is a common engine fault on the Toyota Raize on the 2019–2024 cars, and we rate it major. Putting it right costs $150 to $550 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 8 documented faults on the Toyota Raize.

What you are looking at

No photograph available

We do not hold a verified photograph of the Turbocharger yet. We would rather show none than show a picture of a different part.

What goes wrong

The 1KR-VET turbo routes compressed charge air through a front-mounted intercooler via silicone-clamped hard plastic pipes. The factory clamp torque on the A200A/A201A is marginal and the pipes are subject to cyclical thermal expansion. Multiple owner and workshop reports from Australia and New Zealand document the lower intercooler-to-throttle-body charge pipe loosening at its clamp, allowing a boost leak that sharply reduces power and may trigger limp mode. The failure is more common after the first heat-cycle season (12-18 months) and can recur if only re-tightened without replacing the clamp.

What you would notice

  • Sudden loss of power or limp mode, especially after the engine reaches operating temperature
  • Audible hiss or puffing sound from the front of the engine bay under acceleration
  • Fault codes P0299 (turbo underboost) or P0171 (lean mixture) stored in ECU
  • Power loss that temporarily resolves after the engine cools, then returns with heat

How to check it

Where to look. Lower intercooler outlet pipe, front of engine bay behind lower grille

With the engine cold, physically push and twist each intercooler pipe at its clamp — any movement indicates a loose or failed clamp. Start the engine and listen for a hiss under light throttle from the front of the engine bay. A smoke test through the intake is the definitive check. Inspect both the upper (intercooler inlet) and lower (intercooler outlet to throttle body) pipes.

Parts involved: Turbocharger.

What it costs to put right

$150 to $550 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

  • “Have the intercooler charge pipe clamps ever been inspected or replaced?”
  • “Has the car ever gone into limp mode or lost power suddenly during acceleration?”
  • “Has a boost leak or smoke test been performed on the intake system?”

Now check the Toyota Raize you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Where this comes from

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.

Toyota Raize buyer questions

Is 1kr-vet intercooler charge pipe clamp loosening serious on a Toyota Raize?

We rate it major and common on the Toyota Raize. The 1KR-VET turbo routes compressed charge air through a front-mounted intercooler via silicone-clamped hard plastic pipes. The factory clamp torque on the A200A/A201A is marginal and the pipes are subject to cyclical thermal expansion. Multiple owner and workshop reports from Australia and New Zealand document the lower intercooler-to-throttle-body charge pipe loosening at its clamp, allowing a boost leak that sharply reduces power and may trigger limp mode. The failure is more common after the first heat-cycle season (12-18 months) and can recur if only re-tightened without replacing the clamp.

How much does it cost to fix on a Toyota Raize?

$150 to $550 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Toyota Raize years are affected?

Our research records this fault on the 2019–2024 Toyota Raize. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

With the engine cold, physically push and twist each intercooler pipe at its clamp — any movement indicates a loose or failed clamp. Start the engine and listen for a hiss under light throttle from the front of the engine bay. A smoke test through the intake is the definitive check. Inspect both the upper (intercooler inlet) and lower (intercooler outlet to throttle body) pipes. Look here: Lower intercooler outlet pipe, front of engine bay behind lower grille
