I believe my fuel pump was cracked

Filed Oct 2, 2025 · Fuel system · NE

The high-pressure fuel pump detached from the cylinder head. The dealership confirmed diagnostic trouble code P228C and reported that one mounting bolt was missing and another bolt was broken off inside the cylinder head, causing the pump to come loose and fail. The damaged parts were replaced at my expense and the components are available for inspection if needed. This failure caused loss of engine power and unsafe drivability, putting my safety and the safety of others at risk. The problem was confirmed and documented by a Chevrolet dealer service center. General Motors has inspected the issue through their dealer network but has denied coverage because the vehicle’s VIN was not included in Recall 18V-18V‑358, even though the failure matches that recall description. Warning symptoms included weeks of engine misfires, loss of performance, and eventually complete power loss while driving. These symptoms first appeared shortly before the failure occurred.

My 2016 Chevrolet Malibu Limited (VIN: [XXX] ) experienced sudden loss of power while driving on 9/11/2025 and set code P228C. The dealership diagnosed the problem as the bolts coming loose from the high-pressure fuel pump, which caused the pump to detach from the cylinder head and become damaged, requiring replacement. This failure directly matches the defect described in the federal safety agency Recall 18V‑358 (GM Campaign 18188/18268). That recall explains that the high-pressure fuel pump can detach from its mounting due to a weld failure, leading to oscillation, damage to the fuel system, and an increased risk of fire. Although the dealer phrased it as “bolts came loose,” the result is identical: the pump detached from the cylinder head and damaged the fuel system. Despite this, my VIN does not show an open recall. GM Customer Assistance told me the repair would not be covered because of the vehicle’s age and mileage (current mileage 129264), even though recalls are federal safety obligations that are not limited by warranty coverage. I am requesting that the federal safety agency review this exclusion and ensure Recall 18V‑358 coverage applies to my vehicle. This defect creates a serious safety risk of fuel leaks and fire.

A couple days ago I went to drive my car and it took a second to actually turn on and it was shaking way more than usual and pooped up with a message saying “engine power is reduced” I haven’t drove my car since because i tried and it was moving very slow, and i also didn’t wanna cause further issues. For some time now my car has been shaky. i have taken it in and balanced my tires because of this issue and nothing had helped. I am always scared to drive it because it has been so shaky but now that this message has popped up it’s even worse and it’s during my whole drive. Also every time i park it isn’t connecting and says “shift to park” even though it is shifted into park. i have to shake it and press some button to go all register that it is shifted into park and can shut my vehicle off. I have read every where that this issue has happened to so many 2016/2017 chevy Malibu’s. I have read the dangers and i do not feel safe driving my car like this. I also didn’t have my car when there was a recall on this exact part before. and i’m guessing the dealership who had it before me did not fix it, causing the problems to worsen other parts of my car. I can’t drive this car due to the safety and i believe it should be a recalled. I am not totally sure what is doing it but as of all the other people online, they said it has to do the gas pedal (2k replacement) and fuel pumps and also could have burned wires which my car also has. thank you.

I took my car to to Firestone to have the brakes checked because I had a stiff brake pedal and could only use my emergency brake to stop. They did a basic and advanced diagnostic and said that the brake booster that I have has been recalled and also other equipments on my car has been recalled and I must bring it to a dealership. I searched my VIN and nothing popped up even though months ago I was emailed a recall notice on the fuel pump system and Air bags and it has never been repaired in my car even from the past owners.There have been 10 recalls from Malibu's manufactured in 2016 and my car shows every sign and indication that it is one of those few selected. My VIN should be updated or investigated for parts in my vehicle that have been recalled. The Car stops when idle for two minutes or longer and shuts off the engine and air if you use the USB outlet there is a serious electrical problem which is also a safety hazard according to the federal safety agency guidelines.
