General Motors has released a new technical service bulletin to dealerships regarding an issue with the evaporative emissions purge valve in select units of the 2019 Chevy Traverse full-size crossover.
In the service bulletin, The General states that 2019 Traverse units equipped with the naturally aspirated 3.6L V6 LFY gasoline engine may have a condition where the evaporative purge valve does not fully close. If this condition were to occur, the engine has the potential to run rough, hesitate, or stall at idle speeds. In addition, the Malfunction Indicator Light – or Check Engine Light – could illuminate, which would indicate that a diagnostic trouble code was set.
To remedy this situation, certified GM technicians are to replace the evaporative emissions purge valve as necessary, while the repairs will be performed at no extra charge to the customer.
Notably, this technical service bulletin will be available for quite some time, as General Motors stated that affected vehicles will be covered for a period of 15 years or 150,000 miles – whichever comes first – from the date that the vehicles was originally placed into service. Additionally, this repair is tagged as bulletin number N232395300.
It’s worth noting that other GM vehicles equipped with the 3.6L V6 LFY engine, in addition to the turbocharged 1.4L I4 LUV gasoline engine, may also be afflicted with this issue. With that in mind, the following vehicles are included in this technical service bulletin:
As a reminder, the 2019 Chevy Traverse was available with one of two powerplant choices, including the turbocharged 2.0L I4 LTG gasoline engine, rated at 257 horsepower and 295 pound-feet of torque, and the aforementioned 3.6L LFY engine, rated at 310 horsepower and 266 pound-feet of torque. Both were mated to the GM nine-speed automatic transmission.
Under the skin, the Traverse rides on the long-wheelbase variant of the GM C1 platform. Production takes place at the GM Lansing Delta Township plant in Michigan.

The issue with the evaporative emission purge valve has been troublesome for several years back. Almost any car / truck with the 3.6 liter engine has had this come up. Have replaced this in a 2016 Chevrolet Colorado and 2016 Chevrolet Equinox, both with the 3.6 liter Hoping the replacement part has the problem corrected. Colorado was easy to swap, the Equinox was in a more crowded location.
For the Colorado, the 3.6L LFX engine last used in MY 2016 changed to the LGX engine for the 2017 MY. Did GM switch the rest of the lineup to the LFX engine for MY 2017+ too? If so, does the LFX use the same purge valve as the LGX engine?
They can add 15 yr and 150,000 warranty for the purge valve, how about doing the same for the 8 spd transmission.
Cost me $175 to replace in my 2018, Traverse high country. I’m sure GM will reimburse me.
Just finished replacing my myself on a 2019 traverse and now I see this article. GM should sent notification to people right away, that’s why I’m looking into a different car manufacturer.
I’m curious why the 2018 Traverse isn’t included in the TSB. It’s the same engine suffering from the same problem. I had to pay to have to replaced after my Traverse started having issues starting, stalling, and the auto stop not kicking in. 2018 owners who have already had to pay out of pocket for this repair should be reimbursed.
They need to extend it to 2015 for the Buick Enclave I had that problem with mine
I’ve already paid to replace the valve in my 2019 Traverse. I couldn’t renew my tag as long as the check engine light was on. Maybe GM will reimburse me??
I have been waiting a month and a half for the purge part which my dealer says is on back order. It is for my 2021 Trax AWD. The check engine light came on at 29k miles. Car is running rough, have switched to mid-grade fuel.
Had my 2021 trailblazer purge valve done a few months ago. This is an emissions aren’t they warranted for like 8 yr 100,000 miles? Seems like they are definitely having problems with this part. Like the prism/Corolla from way back.
My 2015 check engine light kept coming on and it was the purge valve and now I have a 2018 traverse and low and behold check engine light comes on purge valve / evap system this is the last traverse I buy….
I have replaced that valve twice already in my 2011 Traverse. My symptom is that the vehicle has great difficulty starting after filling up with gas. Once it starts the first time it’s fine again until the next fill up. The first time I accused the gas station of selling me bad gas. They were very nice about it but a quick Google/ YouTube search revealed the problem. It’s a cheap aftermarket part available on Amazon and a five minute swap, but the reviews all say the aftermarket part will fail after several months, and mine did. I had just resigned myself to replacing it every 6-8 months. Now that I know this, I’m going to see if I can get them to give me an OEM part and call it a day.
Just replaced the valve 2 weeks ago, where do I file a claim?
