Vehicle System Malfunction
I have 2019 3 Sedan AWD. Twice now in the last couple of weeks it has displayed this message on screen "Vehicle System Malfunction Have the Car Inspected." Also the car went into some sort of limp mode - still runs, but at about 50% power. Today the car showed this message just after I left...

我第三天开着新的cx30。今天，我看到了此消息。
“车载网络故障。检查车辆。”
有人看过吗？服务部门尚未开放，我明天将与他们联系。

我也是。我只买了三天。今天早上看这个标准。您是如何解决的？

If you follow the thread bruceboss posted, it is thought this error message may be associated with an exhaust issue, though I haven't read any post confirming this or expanding further on the resolution. Anyone who has this problem, please keep us all updated on what the cause and correction is. Not good......

Sorry I haven't posted any updates.
I brought it back to service department on the next day after I posted this. The service person said this message showed because it had not received any satellite signal for over 31 miles. They said some wire was loosened. They rewired it and cleared the message. No problem after that,

Thanks for the update tcheng! Looks like this may be two separate issues 1) In Vehicle Network Malfunction 2) Vehicle System Malfunction. I cannot see that an issues connecting to a satellite would initiate a limp home function with reduced power as described in the Mazda 3 forum. Hopefully that issue does not carry over to the CX-30.

My new cx-30 also lit up with the network malfunction message on day three. The dealer assured me that it would not affect performance, but ( as a previous post mentioned) that it had to do with Mazda not receiving some kind of signal. Unfortunately, I have to go out of town ( not driving, though), so my appt is in a couple of weeks. I’ll let you know what the outcome is.

Hi, I am hoping the service team at my dealership will be able to fix this issue in my CX-30. I have been experiencing the same "In Vehicle Network Malfunction" since purchasing the vehicle a couple weeks ago. It started the day after I brought it home and has been back to the dealer twice already with them not being able to sort it out. As it stands the only thing I have noticed it affecting is the GPS on my phone apps not being able to locate my vehicle which has been very unsafe especially if you rely on GPS to get you to where you are going. Fingers crossed!

Follow—up on previous post. Took my cx30 in. All connections checked out. Mazda has identified a problem with the gps antenna in the dashboard and is redesigning it. Apparently it picks up too much background noise ( or something like that). The message was cleared. If it appears again, I will need to have the antenna changed, when the improved version is available. It doesnt affect performance.Luckily, I don’t have any need for the gps.
What exactly does "I don't have any need for the gps" mean? If the car is designed to have GPS and use it, I'd think this would be point of concern for you. At least for me it would be.
What trim level are you driving? Maybe update your profile?? The Premium with the cylinder deactivation in the 3 are the ones that seem to be experiencing this type of issue.

It means that right now, I know exactly how to get everywhere I want to go and do not use gps for directions. This is not to say that the antenna doesn’t work; it might, even if it also generates an in-vehicle network malfunction message. So, while it‘s annoying that the new car has a problem with the gps antenna, I can drive quite safely and comfortably until Mazda comes up with a new one ( which I was told they are working on).
I would be concerned, if, for example, I was told that in the manufacturing process metal filings were left in the engine ( oh, wait, that’s the Sonata) or that my head gasket was faulty ( that was the three Jettas I owned, one with fewer than 2000 mi.) ) or that for no apparent reason the car automatically braked when backing up ( I’ve heard Volvo had some trouble with this). This a minor problem, and the antenna will at some point in the not too distant future be replaced.
Well, I'm glad you're not concerned. Though, since the car does not have a built in navigation system, I'm still not sure how the GPS antenna relates to you knowing where you are or are not going. Did you purchase the optional navigation SD card? The car DOES have a built is GPS compass, but that of course has nothing to do with where you're headed. If I'm being daft, my apologies, but I'm not sure what you're even talking about.
I also had the "Network Malfunction" alert show up on my 1500 mile Select package CX-30. My dealer suggested I could bring it in or drive it and it should clear itself. I drove it a couple of days, a few trips and restarts but no luck. After finding this service bulliten https://static.nhtsa.gov/odi/tsbs/2019/MC-10159202-0001.pdf I disconnected the negative battery terminal for 30 minutes and that cleared the alert. If it shows back up I'll take it in to the dealer and report back. Cheers
Thanks for the update. I found another service bulletin: https://static.nhtsa.gov/odi/tsbs/2020/MC-10171791-0001.pdf . Looks like the "Network Malfunction" alert has a myriad of causes including the GPS issue your dealer found and bad connection reported by TCheng. Fingers crossed mine does not re-appear.
