BMW 328I misfire problems

Filed Jul 17, 2026 · Electrical, Engine · NV

The engine intake tract, PCV infrastructure, and the main lower engine wiring harness loom failed due to improper reassembly during Federal Safety Recall 24V‑608. The technician left the main intake coupler completely loose and spinning freely by hand, and left the MAF sensor crooked. This introduced a massive unmetered air leak and severe vacuum leaks. Simultaneously, the technician over-tensioned, pinched, or damaged the Cylinder 2 wiring loom components. The vehicle is currently parked dead and untouched at my residence, and it is 100% available for immediate federal or corporate inspection.The unsealed intake tract and damaged wiring harness caused the engine to run dangerously lean at highway speeds. This resulted in sudden, violent engine shuttering, rapid deceleration, severe mechanical engine knocking, and a terminal Cylinder 2 misfire. This component failure caused an immediate loss of vehicle propulsion on a high-speed public highway, creating an extreme risk of a high-speed collision and leaving the vehicle completely disabled. The issue has not yet been physically inspected by a third party because the vehicle is unsafe to drive. I went to the originating dealer (BMW of Henderson) in person on July 16, 2026, to coordinate a safety re-inspection under an active BMW North America Corporate Case. Dealership management actively obstructed the safety process, gave technically impossible justifications regarding the recall execution, and flatly refused to dispatch a complimentary flatbed tow. They attempted to hold the safety re-inspection hostage behind out-of-pocket customer towing costs and upfront retail diagnostic fees. There were 0 mechanical warnings or symptoms prior to the recall. The vehicle was meticulously maintained with 5,000-mile oil changes and a perfectly tight timing chain. The severe drivetrain malfunction warnings, violent front-end shaking, and terminal engine knocking appeared after picking up my car.

Check engine light came on and car began to slow down on the expressway going 45 mph. My car now does not start and will not turn over. Before all of this happened my car was misfiring and a warning came up saying Engine Oil pressure Low. I just received an oil change a week prior. Now my car doesn't work and I cannot drive it at all. BMW said my timing Chain is broken and I have an oil leak. I will need a new engine. My mechanic said my entire engine needs to be replaced.

My vehicle was not included in BMW Recall "23V‑707: Replace Vanos Adjustment Unit Screw Connection" but has suffered the same failure described in this recall. My VANOS adjustment unit screws came loose and caused my engine to completely stall in the middle of traffic on a very busy road [XXX] ). I lost some braking ability and narrowly avoided a major collision. I've been having issues with misfires related to my VANOS system and today I found that despite being told my vehicle wasn't affected by the recall, it is experiencing the same issue as the recall above mentioned. My vanos adjustment unit bolts on both exhaust and intake sides of the engine were all much more loose than factory specification, so much so that I was able to remove 6 of them with my fingers alone. I think there should be a full safety recall on this issue as it seems to affect a much wider variety of cars than initially thought. I was able to re-tighten them to factory specs, but I have no confidence that it will stay that way. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicles check engine light came on, and the car started to misfire and idle hard when driving. Jack Furrier Tire and Auto ran the code, and it came back with peoblems with the cam shaft. I brought it to BMW, and VANOS bolt (recall) code was confirmed, but they told me it was a problem with internal piece missing from the oil filter. I asked if the car was safe to drive, and they confirmed and also told me the car is having other mechanical issues I should be aware of. The service agent described possible future problems with transmission and told me that there was no remedy available for recall yet, so I need to wait. I paid to have oil filter replaced. A week later, I was driving myself to work and my daughter to daycare when the car began to stall out and misfire in traffic. After bringing it back to the dealership, they replaced 1 spark plug free of charge and advised me that the car was coming back with other codes. I addressed the safety risk and the continued mechanical breakdown of the car systems if I continued driving it, and I was encouraged to trade the vehicle somewhere. I will attach an email I sent detailing further frustration I have experienced with BMW. After speaking with customer relations, I received the same reply, which is yes, there is a safety risk it is minimal and unfortuanly, there is no remedy available yet. The following was my reply when asked to complete customer survey: I am getting no help with a car that has a recall on it and being told the exact thing at every level I have presented my legtimate concerns. With no viable or reasonable options. I basically have to continue driving my car and risk car further breaking down and put my family's safety at risk with hope that "it's low probabilty". Somehow, these are my only options on a vehicle with a recall.

On all e90 series 3 (2008 bmw 328i), the pcv valve fails and is welded into the valve cover, thus if it leaks or gets cracks in the orange membrane, it will cause car to stall.. I almost crashed 2x and this part should be recalled..it affects the fuel air ratio in bmw e90, and the car will run lean and not receive enough gas as air is leaking from the broken membrane in the pvc valve. Bmw will throw engine codes with lit check engine light on dash. This should be a recall as the whole valve cover has to be replaced to replace a defective $10 pcv valve which is ludicrous...the dealer charges thousand dollars and up to replace a ten dollar part. The car has rough idle and will stall, creating a dangerous driving situation and fatal accident . Please recall to have bmw dealer fix these plastic pvc valves on e90s...I have enclosed pic of the valve ..it also has a spring but the plastic orange mebrane cracks, breaks and leaks air inside valve, causing check engine codes, rough idle and stalling of vehicle.. The valve is located on top of valve cover, welded into valve cover. Please help..thank you state florida p.s. Heat causes the pcv membrane to crack more~~pic enclosed of pcv valve its welded into top valve cover..no other car has a pcv valve mounted this way so whole valve cover needs to be replaced~ thank u

I've had my car for less than a year, and started having issues with my engine around cold weather season. I would constantly get a light signal on the dashboard indicating that my engine needs coolant due to it overheating, although my car remained up-kept with coolant and fluids. there were times where I had to stop my car on the road due to an extensive amount of smoke and burning odor coming from the engine compartment, after being serviced a numerous amount of times, the only issue found was in regards to my engine overheating, and supposedly fixed by adding more and more coolant. eventually my engine gave out after taking a short 30 minute trip to my parents home on thanksgiving day. Now that a recall has been placed on my vehicle, I have an understanding that a PCV valve heater malfunction can cause an engine to overheat, and when not repaired, it can cause unrepairable damage to an engine. I also have an understanding that a valve heater malfunction can cause coolant to leak out, resulting in the engine overheating regardless of how much coolant is put in it. I have an understanding that a bad PCV valve heater can result in a rough idle, engine stuttering, and a drop in fuel efficiency, all of which I've dealt with. I've reached out to my local BMW shop in regards to this recall, and they refuse to even take in my car to look at it being that my engine is already no good, although the reason for my engine going out is most likely due to this recall. my car is sitting with a faulty PCV valve heater and the damage that its done to my engine, and the BMW shop of macon is telling me that this recall has nothing to do with my car without even looking at it, when I know for a fact the issues I've had with my car relates to the recall.

The timing chain went out. Warranty was extended to 70,000 miles or 7 years, but this is outside the range of many of the incidences, including mine. I'm getting multiple misfires and you can hear the timing belt when the engine starts, if it starts.

The car is experiencing rough idles and an imbalance in the overall performance. The PCV valve is not allowing enough air to return to the combustion chamber, creating a rough idle as the levels are imbalanced. It’s also causing a lean air to fuel mixture, oil leaks and increased fuel consumption. The PCV valve hoses became blocked by built-up moisture causing high pressure to be built up in the engine crankcase. The only way for this high pressure to escape is up through the cylinders and out of the gaskets, thus causing the gaskets to lose their seals. Oil is now able to leak out of the gaskets because the seal has been ruptured. I’ve already spent thousands of dollars on services including gasket changes.
