General Motors has issued a new technical service bulletin to dealerships for select units of the 2020 Chevy Trax subcompact crossover.
In the service bulletin, The General states that 2020 Trax units equipped with the turbocharged 1.4L I4 LUV gasoline engine may have a condition where the evaporative emissions 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 vehicles equipped with the naturally aspirated 3.6L V6 LFY 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 quick reminder, the U.S.-market first-generation Chevy Trax ran from the 2015 to 2022 model years, with a mid-cycle refresh introduced for the 2017 model year. At the time when the first-gen Trax was discontinued – and before the all-new 2024 Chevy Trax was unveiled – the Bow Tie brand’s entry-level crossover was powered exclusively by the turbocharged 1.4L I4 LE2 gasoline engine, which was rated at 153 horsepower and 177 pound-feet of torque.

It’s also a known issue on the LFX engine. I replaced it on our 2015 Impala, fortunately not too difficult. Service bulletin, not.
2019 Chevy Trax with targeted engine. Purge valve coded and is bad. 13k miles on it and of course out of warranty! Not getting anywhere with dealer. Why just the 2020’s. GM retiree here, may be time for a brand switch! So frustrating.Last circus was my Equinox with excessive oil consumption….finally cracked the block! No help there either!
My 2024 Chevy Trax is waiting for a new evaporation vacuum purge pump. It has been on order since June 4. I bought my car last July, and now I’m driving around with my “check engine” light on. I started to buy a Toyota; should have!!
I have a 2022 Chevy Trax. Purge Pump Issue also. I want to do it myself but I am unable to locate it under the hood. Any help would be appreciated. I went to dealership to buy the pump and it will cost $199.00
