Showing the 60 model years where P0299 appears most; it is on file for 228 in total.
A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.
What it gets filed under
When owners report it
miles, typically
Half of the 12 owner reports naming P0299 that carry an odometer reading fall between 40,000 and 69,000 miles. A code that shows up at 30,000 miles is a different proposition from one that shows up at 130,000, and that difference is the single most useful thing in this record.
What owners said

under warranty until 50k car throws a p0299 code - turbo underboost condition present - coolant migration from a faulty VW/AUDI water pump is sending coolant into vacuum lines causing catastrophic engine issues - car can not be driven
The vehicle is displaying an active diagnostic trouble code P0299 (Turbocharger Underboost condition).The manufacturer, General Motors, is fully aware of this exact component defect and has issued corporate Special Coverage Adjustment…
The vehicle was taken to an independent mechanic, where it was determined that the wastegate actuator needed to be replaced, and DTC: P0299 was retrieved
The defect causes sudden loss of motive power at highway speed (65+ mph), usually after 40+ minutes of driving, with the powertrain warning light and code P0299 (turbo underboost)
The vehicle developed insufficient vacuum to the boost-control system, resulting in a P0299 turbocharger underboost fault and reduced engine power

What P0299 means
Source: SAE J2012 / OBD-IIThe turbocharger or supercharger is not making the boost the computer asked for.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0299
Source: NHTSA files and the OBD-II standardCan I keep driving with P0299 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
