What owners report
Already had turbo go on this car once back in July 2022. Mechanic replaced turbo with another one (used with 20,000 miles on it) due to the turbo for this car being on backorder. Now my car is throwing P0299 after about 20,000 more miles being put on the used turbo and a P0420 code. Changed rear catalytic. Changed upstream O2 sensor, changed wastegate solenoid, turbo seems to be working fine, no noises, but losing power going up hills at highway speeds. Seriously unhappy and no recalls on this vehicle but it has the same turbo as other vehicles that has had recalls!!! I think this should be a recall!!!
Turbo Charger failed while passing a semi-trailer truck causing a severe lack of power and almost causing a head on collision with on-coming traffic. I had 3 passengers at the time. The problem has been confirmed by a independent service center and I am getting a second opinion from a dealer on 2/3. The check engine light did come on when it happened. There were no symptoms prior to failure. I have since researched the problem and found that Turbo Charger failure is the #1 issue with this make and year.
Engine light is on and vehicle is sluggish on hills and keeping up in traffic. Rpms run high if I try. Error code p0299 shows on scanning device- turbo under boost. I have 112,000 miles and need turbo replaced already. this vehicle is very well maintained. I did see a special notice for the GX version of this vehicle. But dealer says my vin does not qualify
Unknown issues w/ sensors and wiring lead to turbocharger failure. This led to spontaneous acceleration issues on the highway. Less than a year after the warranty covered the replacement of the turbocharger (less than 60k miles on the car) the turbocharger again failed (64k miles on car).
