The turbo underboost condition can also be the hose- check the hose connection at the intercooler - they are known to pop off or leak a little at the connection. It is somewhat obstructed to see so look from the bottom as well. Second cause is the boost solonoid under the intake - check the small rubber hose to it they will get brittle and split at the nipple connection...then check the solonoid itself. Only then would I look at the turbo being the issue. If so, it is about an 1 hr to 1,5 hr job and replace the oil seals including drain back tube seal.

At that speed youve clearly done a few of those. Up here the Michigan loctite from the road salt will add some time.
Yes it will! Rust adds time and frustration. It literally is just 4 bolts holding it on once you remove the heat shield and associated lines.At that speed youve clearly done a few of those. Up here the Michigan loctite from the road salt will add some time.
A local mechanic went over the car today and said everything looked great, no stored codes either. Just the stealership trying to make $2000 for a new turbo. Their replacing the seven year old tires on it on Friday and will be returning the rent a car.
No they're not - at the time of the diagnosis, the vehicle had a P0299 and a new turbo was probably the correct repair. As for why the fault has not reoccurred, that's anyone's guess.
I've got 90k on the Trax. Same engine. Coolant will slowly leak from everywhere. But the more you top it off, the more it will leak. Let it sit a tad low. It's ok. No other problems.
