2025 Chevrolet Equinox Engine Problems

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. It will potentially go away as the weather is hotter, but if a chilly night or morning comes up, then the light will come back on because there is moisture buildup on the PCV Valve when the temperature drops that causes the light to come on. With all of the complaints I have read online for this very issue, I would like to see NHTSA step up and make Chevy fix their problem. Thank you.

Check engine light was on after just sitting in the snow for two days. Dealer is saying that it is a fuel injector and something with the gas. I hope this fixes it.

My daughter was driving and she said the check engine light started blinking and the car slowed down immediately. She had to press the gas to get it into a gas station.

The contact stated that the failure had occurred on several occasions, and the brake pedal needed to be depressed very hard while attempting to stop the vehicle. The contact stated the vehicle had started independently two to four times in a row. No warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 14,417.

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. On The HIGHWAY and Engaged the Parking Brake Automatically. This is unbelievable and extremely Dangerous. How or why did some engineer think this was good idea for the vehicle to Lock Itself down ON THE ROAD!

My car threw on the check engine light and a note flashed on the screen and car just slowed down immediately. I had to press on the brakes really hard to get it home and then the transmission wouldn’t go in reverse. I took it to the dealer and they couldn’t duplicate the problem but said the battery contacts weren’t tight.

Yellow check engine light comes on and off. Car isn’t 1 yr old yet im being told there is no recall yet or a fix.

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. The check engine light came back on and now we have to take it back to the dealership 9/2/2025. This is super frustrating and an inconvenience to have to take a brand new vehicle to the dealership every day. We have had the vehicle into the dealership a total of 8 times so far with a 9th visit on 9/2/2025 for the SAME issue when will chevy get this figured out?
