Chevrolet Trax grinding brakes problems

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

I work from home, so I drive my car maybe once a week and only on flat highways. One day, I heard a loud booming crack and then suddenly the vehicle was making a grinding noise and pulling strangely. I drove directly to a mechanic and had them looked at the vehicle since it was highly concerning to me. They said that the rear differential had split suddenly and that it was actually extremely dangerous that I had been driving still. They said if it had fully cracked it might have ended in my death! Again, this car is very underworked and not driving over so crazy terrain or anything to cause damage. The mechanic also mentioned that they've seen this problem in this vehicle make a lot, stating, "it's very common". I had to drop 3 grand to fix this. Given the danger and that it's a common problem I'm surprised this isn't already a recall.

In the last 30 days of obtaining my first brand new vehicle, there have been a couple of incidents where I have put my truck in Park on an incline (hilly street or driveway), and you can hear the brakes grinding once my foot has been removed from the brake pedal. It gives the impression that the brakes have not stopped. It’s unusual to hear and in my concern, I activate the emergency park for extra security. It’s a little scary to think that the brakes won’t do what they’re designed to do.

I have recently heard what could best be described as a squealing sound. I could also smell fuel inside the vehicle while driving. I thought it was oil that had leaked onto the serpentine belt and had it replaced but the noise continued. Listening closer I realized it was coming from the area around the intake manifold. Searching online I found several YouTube videos and comments from people mentioning loose spark plugs caused their issue. Checking mine I found that two of the four spark plugs were loose enough to not require a wrench to remove them. Tightening them eliminated the noise. I have owned this vehicle since it was brand new and have never asked a mechanic to check or replace spark plugs, nor have I done it myself. I did recently replace the intake manifold, which required removing and reinstalling the ignition coil. I feel like loose spark plugs represent a fire hazard as it allow the fuel to blow past the cylinders and into the engine compartment.

Ac no longer works. Ac only blows warm air no cool air. Three years is very soon for a car to have issues with the air condition. There is no AC. The heater works fine. However, when I turn on my AC the car vibrates and makes a grinding sound. Feels unsafe to drive.
