Unknown. The car seems to stall or slip when accelerating as is misfiring. It cuts off in the middle of the streets after coming out of auto stop mode. Pcv valve keeps popping up as issue. I had the pcv changed o2 sensors checked cleaned throttle body and air filter changed. The car still gives same problem and engine power reduction keeps popping on dashboard.

Purchased new in 2019 – 32k miles - Oil changes every 6 months. Lightly driven, no modifications, all original engine components and tune. Engine developed a significant miss. Several warnings on Stabilitrak, ABS, and P0300. Significant oil leak at front of engine, oil is splashed all over the passenger side of the engine compartment. There is significant ‘chugging’ of air and oil from the dipstick tube and from the oil filler cap. This condition indicates excessive pressure leakage to the crankcase that is caused by a crack or failure to the #1 piston which is a very, very, very common failure with an extensive and indisputably documented history with the 1.4 engine throughout the history of the Chevrolet Cruze since its introduction. Compression test shows cylinder #1 at about 80 PSI while cylinders 2, 3, and 4 are at 190 PSI. This proves that there is a catastrophic compression leak down into the engine crankcase causing the misfire P0300 and the resulting excessive crankcase pressure causing the oil leak at the front of the engine and the expelling of air and oil from the dipstick tube and from the oil filler cap. This needs to be a warranty repair and the cost covered 100% by GM as it is a known defect with this engine since it has been first been used in their cars. Refer to: GM Bulletin: 18-NA-171 - [XXX] GM Bulletin: PIP5490D - [XXX] GM Bulletin: PIP5421 - [XXX] Reading through the extensive volume of posts on the #1 piston failure, GM/Chevrolet should have acknowledged this and a recall should have been issued and the warranty extended to cover an piston and/or piston ring failures with the 1.4 engine no matter what year or what vehicle it was installed in. I have additional links documenting the frequency of the piston and/or piston ring failure in the 1.4 engine: INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle first prompted that it had a recorded a misfire in cylinder 1. Changed the spark plugs and coil packs. Vehicle noted a misfire in cylinder 1gain and said service stabilitrak. Changed the pcv valves and other vacuum pieces on the valve cover along with the MAF sensor. Engine ran fine on test drive, then dumped oil on the ground as I was pulling back into the drive way. Gasket comes on the oil pan so that’s getting replaced next. Then I have to check the fuel pressure sensors and fuel pump to see if they’re failing because apparently GM has a points bulletin out about them not being so good. Plus hope the engine isn’t ruined when it lost all its oil.

The contact owns a 2018 Chevrolet Cruze. The contact stated while driving 25-30 MPH, the vehicle felt imbalanced and was shuddering. Additionally, the engine emitted abnormal knocking sounds. The check engine warning light was illuminated. The contact then parked the vehicle a block away from his residence. The contact who is a certified independent mechanic, diagnosed that the fuel injectors had failed. The contact also diagnosed that the fuel injector had melted and fused into the number one cylinder, causing the engine to misfire. The contact replaced the fuel injectors, the spark plugs, the fuel line, the fuel harness, and the vehicle software were flushed. However, the failure reoccurred. Upon further investigation, the contact became aware that the engine inside the vehicle was not the appropriate engine as it was 1.5 liter and its specifications indicated that it was an engine specifically designed for a Chevrolet Malibu while the vehicle was a Chevrolet Cruze. However, the original owner of the vehicle, who was the contact's neighbor, had never replaced the engine. The contact then determined that the failure was associated to the federal safety agency Campaign Number: 19V642000 (Electrical System, Fuel System, Gasoline, Engine). The contact notified the dealer where the vehicle was originally purchased and informed them that the engine installed was not the appropriate engine. The dealer disregarded the information and informed the contact that he would be responsible for the cost of the repair. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 12,000.

Engine performance dropped noticeably, tire pressure system alert lighted, and stability track turned off. Then within a short period of time, some 30 minutes, the engine warning light activity (steady). All of this happened shortly after the 3-year warranty expired although I was having some engine roughness a few days before three years. Made an appointment at the Chevy dealership and the issue was diagnosed to a misfire on cylinder #1. Apparently, the insulator around the center electrode of the spark plug separated and slipped down. After a bit of research and asking the dealer for Chevy TSB #PIP5657D, the federal safety agency TSB #10201263, I was startled to find this is a somewhat frequent-enough problem affecting a number of GM models using 1.4L engine as used in my Cruze. I had a forthright conversation with Chevy dealer that this was a warranty issue as my OnStar alerted me to an emissions system malfunction. I also called GM and ACDelco, the spark plug manufacturer, and they claimed nothing or no issues. This is a safety concern to me. Paid almost $400 to have four spark plugs replaced at 3-years and only 7,000 miles; ACDelco warrants the spark plugs for 7-years or 100,000 miles!. Unacceptable.
