Check Engine Light Code P0496 evap. Emissions system, high purge flow
The contact owns a 2019 Chevrolet Traverse. The contact stated that while starting the vehicle, the check engine warning light illuminated. The vehicle was taken to Auto Zone, who determined that the canister purge valve needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 97,000.
Evaporation system is defective and the canister purge valve does not close completely resulting in environmental toxicities put into the air. A check engine light on and after 3 fixes the issue is still present
Torque converter is bad. Codes will not come up when test ran. Mechanics mis diagnose the issue until it’s too late. Mechanic now doesn’t think it’s worth it to replace- wants whole new transmission.
I have had to replace my evaporative emissions purge valve 3 times on this my 2019 Chevy Traverse. I have had it for a year and a half.
One year ago the check engine light came on. Diagnosis stated EVAP system leak. Replaced a bad purge valve.now almost a year later the engine light comes back on car also started struggling shifting and shift to park would come on when car was already in park. Diagnosis states a large leak in EVAP system, smoke test determined leak was coming from the fuel canister. Canister was replaced and within two trips engine light came back on and car continues to struggle shifting as well as having a rough idle. Another diagnostic test reported bad fuel sensor. 2019 traverse seems to have a lot of EVAP system issues and have been told as well as read that this is a trending issue with this vehicle. With each diagnosis report it states it would fail fuel omission.
On our 2019 Chevy Traverse, the check engine light came on and off several times over the last couple of weeks. After filling up with gas, it would often take 4 to 5 times to get the engine to start as it would keep stalling out after starting. Additionally, on two separate occasions the car stalled out unexpectedly - once while turning onto a road out of a parking lot that almost caused us to get hit, and a second time while in a round-a-bout. The car was checked by a Chevy dealer and it was found that there was a bad purge valve creating this issue. This had previously been recalled on earlier model year Traverses, but not for 2019. It appears this is still an issue for this model year and should be addressed.
