The vehicle suffers from an extreme, unresolved internal crankcase pressure defect stemming from the factory 1.4L Ecotec PCV system and intake manifold check valve. This pressure cascade has caused a total turbocharger failure, multi-gasket oil blowouts, water pump failure, and has now completely blown a critical coolant housing hose off its connection, causing total coolant evacuation. The vehicle is currently parked and available for inspection upon request. The safety of the driver and minority passengers is severely compromised. The vehicle actively smokes from under the hood when turned on, which worsens immediately when the cabin heater is utilized. This indicates highly flammable oil and coolant are leaking directly onto hot exhaust/turbo components, presenting an active vehicle fire hazard. Furthermore, the pressure defect previously caused a catastrophic engine oil blowout while traveling at highway speeds, risking sudden power loss, engine seizure, and traffic collisions. The vehicle is currently deemed completely unsafe to operate. The vehicle's core turbocharger failure was previously confirmed and replaced by an authorized manufacturer dealership under a factory warranty extension. However, the dealership failed to diagnose or repair the underlying PCV/intake pressure defect, causing the new components to fail immediately upon vehicle delivery. The manufacturer has been notified of the failure cascade but is refusing to inspect or intervene without requiring out-of-pocket consumer diagnostic fees. No police or insurance inspections have occurred. began over two years ago with random, intermittent check engine lights accompanied by random error codes, a high-pitched engine squeak, rough idling, severe fuel economy drops, and intermittent engine stalling. The engine eventually developed a heavy knocking sound resembling a diesel engine. Currently, the check engine lamp does not illuminate, but all physical symptoms remain active and increasing in sever

The non return valve in the intake either broke or fell off( apparently defective) causing my vehicle’s check engine light to come and causing multiple error codes. As a result of this defective part it cause my vehicle to vibrate violently ,the lost of power, and ultimately stalling out Nearly causing me getting involved with a very serious accident. As a result of this incident I took my vehicle to the nearest mechanical shop had it diagnosed showing multiple error codes and ultimately revealing a missing part ( A rubber nipple ) which was supposed to be inside of the intake. As stated above the check engine light did come on one week prior to the above conditions as a result of this missing/defective part . I had tried on several occasions with the dealership where I purchased my vehicle from to have the above problem resolved with negative results. My mechanic has confirm with me that this is not the first time he has seen this part missing from other GM vehicles with the same type of engine . I did research about my issue and found numerous reports of this with the same type engine in it since 2012 , Also my mechanic was told by one of the service members of the dealership that they were aware of this problem obviously this is not the first time, but they refuse to have my car towed and wanted me to pay an additional $140 again to get the car diagnosed. The car was rendered unsafe to drive due to the fact of the above problems regarding this defective part . This needs to be addressed , there is no doubt in my mind that someone will ultimately die from this continuous problem with these engines with this particular part. I have kept all the parts that were taken off of my vehicle for further inspection especially if the federal safety agency wishes to inspect it. I am appealing the decision from General motors concerning this Replacement part/ parts that I Purchase to render my vehicle safe and operable.Replacement parts are all GM products !

In february on zero degree day my 2018 trax had blue smoke coming out of the tail pipe and almost stalled car running. I saw another trax that same day with blue smoke coming out of the tail pipe. When I was at the dealership they were returning some one elses trax and it had blue smoke coming out of it. The trax has a 1.4 turbo engine and gm seems to have a problem with the pcv system on this engine. Gm needs to come up with a fix for this problem and there should be a recall on this. You can look on youtube and the mechanics there are aware of the problem. The dealerships and gm seem to not have any interest in correcting this problem. The 1.4 turbo is put in many gm cars. I would think if nothing else this should be a pollution control recall.

When I'm at a stop and try to push on the gas it feels like it's stalling out, I've also had problems with the radio and turn signal, I've had the radio screen be completely black but the radio was playing and on other times after taking it out of reverse and putting it in drive and actually driving down the street the two yellow margin lines still appear on the screen across the radio station and the turn signal seems like the dealer had to replace the overhead light in the car because it did not function as well, it delays when I turn it on it takes a couple of seconds for it to actually start flashing I've also had a problem with the emission and they told me it was because of cheap gas and they replaced something with the emission control and it felt like it was dying out before they fixed it and it still does. I believe september 18th was the last time I took it in for these problems which they could not find out why.
