Bought vehicle in October 2024. About 5 hours after we purchased vehicle the check engine light came on, dealership did reset and everything checked out to be safe and sent us on our way. Fast forward to January (do not remember date) check engine light came on again, this time took it to auto zone to hook the car up to the scanner, it did give an error code of P04FB which is a crankcase ventilation sensor. From auto zone we did take it back to the dealership and the had the same code as auto zone. Dealer ship did reset and acknowledged that Chevy was "working on it" but no fix is available. Everything seemed to be ok until 6/5/2025 and the another time in June when the check engine light came back on and again the dealership reset it. Since June we have had the vehicle into the dealership once a month, July (not sure of date) and 3 times in August 8/26 8/27 & 8/29. …
While driving my 2025 Chevrolet Equinox, the vehicle experienced a sudden power and drivability issue. The vehicle began to decelerate on its own while in motion, even though I was actively driving. A warning notification appeared on the driver dashboard, and shortly after, the vehicle power shut off. This creates a serious safety concern because the vehicle can unexpectedly lose speed and/or power while driving in traffic. The issue appears to involve the transmission, powertrain, or vehicle electrical/power management system. The loss of acceleration and sudden deceleration could increase the risk of a crash, especially at highway speeds or in heavy traffic. This incident occurred while the vehicle was being driven, not while parked. The warning message appeared on the dash before or during the power loss. …
We purchased the vehicle New. Within approx. 300 miles started to hear a bearing noise intermittently while driving. We returned to the dealership to have it diagnosed. We were advised that the could not duplicate it. A few days later the noise was brominate while driving at highway speeds. Returned to the dealer. We were told that it was caused by the Active Noise Cancelling system and that they performed an update(per GM service bulletin) to the control module to correct it. Picked up the vehicle. Driving around town no issue. Driving at highway speeds the noise would come and go. On June 14, 2025. while driving on the highway at 70 MPH the engine shut down. My wife and daughter were in the vehicle in the middle lane of a busy highway. The dash displayed "Automatic Braking Engaged! WHILE TRYING TO GET OFF THE ROAD. The vehicle brought itself to a COMPLETE STOP. …
This is a 2025 vehicle with 25,000 miles and the Check Engine Soon light stays illuminated due to a faulty PCV Valve or possibly a poorly designed crankcase. The engine code is P04FB and is commonly found as an issue when you do a search. As a safety precaution, the vehicle is programmed to not allow the remote start to work as designed when the engine light is on so this issue affects the overall functionality of the car. Having spoken with the dealership, they report seeing that engine code often and that the part is on backorder. The dealership seems to think it's the crankcase causing the issue and not the PCV Valve as the fix they have been ordering for them is the case. …
