2012 Cruze Automatic 1.4T - I've had the car myself for about 2 years. I had an issue with the car electronics acting funky and that was fixed with the negative battery cable recall. Car worked fine since that was done in November of 2015. The car was in the dealership for the ECM programming recall about 3-4 weeks ago, and now this past Sunday, the car freaked out on the highway. All the gauges died, all service lights came on, and the car lost power (step on the gas and you'd hit maybe 2500rpm). Pulled over and when I coasted down to about 5 MPH the car acted like it slammed into gear. I stopped, and shut it down, and ever since it fails to turn on. It doesn't attempt to crank. When you try to start it, the gauges do their self check and then all drop to 0 - the service stabilitrak, service traction control, service parking assist, etc all come on and flash. You hear a buzzing noise from the engine that sounds like the electronic break booster, but the car doesn't try to crank. Sometimes the radio comes on, sometimes it doesn't. Sometimes you can roll the windows, sometimes you can't. The dealer today said the code they pulled is saying no sensors or modules are communicating with the ECM, but they don't know why yet.

I don't know if this could be another negative cable issue, or if something with the ECM may have been damaged with the reprogram. Anyone else have issues after their recall and reprogram?

They seem to not be sure what it is. The service manager who updated me said the technician was "at a standstill" yesterday - not sure why nothing is communicating. I spoke with them this morning and they said I would have an update today, but they close in 40 minutes.

Time to rattle their cage, eh?

Do they at least have you in a car?

I called them and asked for an update - they still have no clue what is causing the systems to not communicate - "needle in a haystack." They said they can't put me in a car either until they confirm it is something under warranty or not. They said they will let me know when they have an update. Sounds like it is going to be there a while unfortunately. Trying to find a ride to and from work is proving to be troublesome.

Still no update - Solid week with no answer on what's causing this. I'm afraid to see the diagnostic bill for this, let alone what the fix ends up being.

Talked to the dealer yesterday - they were able to put me in a loaner car finally. They said they have decided it is either going to be an ECU replacement or wiring harness replacement. I asked if that was covered under warranty, but they said they didn't know and would be calling me today with an update, however I did not get a call today. Hopefully tomorrow I hear some good news. Day 9...

UPDATE:

Dealer called this morning and told me it appears there was a fire in the engine bay which melted the wiring harness, melted an engine mount, killed the tcm and may have damaged the transmission, and also the radiator may need to be replaced. They do not know the cause of the fire- they said it MAY have been an overheating transmission, but have no way to tell. They can't test the transmission because it won't start still, and can't pull data from the ECM due to the melted data line. They told me to get insurance involved due to the fire.

I spoke with my insurance and they said basically anything damaged by the fire would be covered but not the component that started the fire. So if the tranny started it, it is not covered. Insurance wants more information as to damage and cost before they file a claim, and are pushing me to blame recalls and warranty work through GM. I relayed that information to the dealership and they said they needed to talk to their field manager to try and figure out what to do as they have not had this situation before.

Ugh.

Call your insurance company back and tell them to get an adjustor out to the dealership ASAP. That's a bullshit response from the insurance company. I highly doubt the ECM reprogram caused this. While I agree this is very likely a component failure your insurance company, GM, and the dealership need to work out who's paying for what. At most you should be responsible for at this point is your insurance non-collision deductible.
I also doubt the ECM reprogram had anything to do with this. Definitely seems like a mechanical failure somewhere that caused this. I'm waiting to see what the dealership says after they speak with the manager. I'll give insurance a call and see if they can get someone over there too. Oh and State Farm said they're afraid if I do make a claim, they'll drop me because I had too many Road Side Assistance claims recently - all pertaining to this car. Once for the negative battery cable recall, once for coolant leak with the water pump special coverage, and now here with the fire issue. Lovely.

I read about the NHTSA investigations into 2011 and 2012 Cruzes catching fire due to oil dripping onto hot parts due to a missing shield. The fire occurred right below the oil filter, so maybe that is the case? It sucks the dealership doesn't have a more definitive answer on what is happening. Like jblackburn said, I would think the tranny would have given out before catching fire or heating to that point, but I'm no mechanic.

Dealer called back and recommended I contact GM directly and open a case with their claims team, at which point GM and the dealer will work together directly. They said they can try to work with them to get them to cover the costs of getting the car to a point where they can communicate with the ECM and modules so they can try to see what was happening at the time of the incident - although it was over 2 weeks ago, I don't know how long that information is stored.


Hopefully GM will agree to something and we can try to get more information out of the car.

I am going to wait to see what GM and the Dealership come back with - if GM agrees to front the bill to get the car to a point where they can diagnose cause, that's fine with me. At that point, the cause will either be GM taking the responsibility, or if something not under warranty like chewed wires, then I will push State Farm.

Hello,

I did contact the Claims Assistance Team on Monday, but have yet to hear back.

Update: GM contacted me and opened an investigation - on average it takes them 30 days to complete, so we will see what happens.

Update: GM came back and said they found no manufacturer defects in the vehicle.


They cannot determine what the cause of the fire was.


All they know is that some data lines and TPM lines are melted.


Does anyone here know if a non communicative TPM would cause the car to not start? Trying to figure out if I should just bite the bullet and replace/repair said cable - but not sure if that is the actual cause of no crank.

They gave it back partially disassembled. I have all parts with me. I'm trying to probe the harness wires to test for continuity but don't know where this one plug connects.

Determined it plugged into the front of the transmission. Currently testing for continuity of all wires on it.
