@Engdiver nonsense. The brand of antifreeze doesn't cause overheating. You probably had some air in the system or something.

 

Can't say for certain it is the type of antifreeze that made the difference but running at a cooler temperature certainly did. If Chevy put actual temperature gauges in the malibu with a more exact temperature reading it would be easier to determine.

 

Antifreeze is antifreeze. It's the water that does the cooling.
these days you can get inexpensive diagnostic tools (such as. BlueDriver) which give you all kinds of live data, such as exact temperature.

 

Same issue as everyone else . Always has something going on. Since the very first week I've had this car it's felt funny.

 

My wife's 2013 Malibu 2.5L stalls at traffic lights on drive for around 2 years now. I have recently replaced spark plugs, coil#1, cleaned MAF sensor, replaced crankshaft position sensor, added a fuel additive without success.

My next steps before thinking on something more expensive are:
1.- Inspect intake manifold bolts tightness.
2.- Drive vehicle to reach operational temp, then record temperature when stalling (I got an amazon bluethoot and an https://ymobd.com/#/) to do that.
3.- Replace coolant and repeat step 2 to compare data and results.

 

you should do an engine auto stop delete . You can buy a small little cable that attaches to your hood latch Sensor this will disable your auto stop. The problem where every time you come to stop your engine stops or stalls. I bought one-off Amazon for $29. My engine runs much better and smoother.No more.Annoying stalls and stops at stop signs.i think this might have even cured some of the engine codes that where comming up .just put the cable on today I will update on this forum if the problem is solved long term . Even if it doesn't solve the problem of the codes, i'm sure there's a lot of people that are very annoyed with the auto stop feature, this will disable it with no lights on your dash, for open hood and the remote start will still work also.

 

I am joining this forum in hopes that someone has figured out the issue. We have a 2014 Malibu with 140k miles. My wife drives this as her work car. It started with the car stalling at stops, which led me to believe that we were looking at the start/stop feature. This issue has progressed to stalling while driving also. I took over driving this car and began to take notes as to what is happening during the issue. The first time that I personally witnessed the stall, I rolling up to a stop and noticed that the blower fan had stopped blowing. I wasn't even expecting this to happen and believe it distracted me from the fact that the car stalled. This happened around 100yards from where I started driving, so the engine is just getting warmed up. The car started right up and i continued my drive. That is when I realized that it will happen as the car is moving. It was probably 50 yards later that the car seemed to have a misfire, but shortly after it started it come out of that. Later that same day, I had to drive a short distance and was at a stoplight. When the light turned green I accelerated and the car seemed to misfire and die. I quickly started the car and it got me through the intersection before acting up. Now some of you younger generation might not understand this, but it was popping from the exhaust sounding like the old school carburetor key bang which went on for about 50 yards. The car came out of it and drove normal the rest of the drive. Later that afternoon, I went to drop off at a repair shop for them to look at. This time it stalled while the car was stopped, in reverse as I was waiting for a car to pass before backing out when the car began to idle ruff and then die. The car continues to hesitate, run ruff, stall with no codes active. The repair shop has replaced VVT solenoids, cleaned sensors, replaced batteries, replaced BCM module, now O2 sensors trying to fix the issue. I have been driving the car with a scan tool watching any and all data trying to figure out the issue, but it is hard to trace when the issue is intermittent. I see all these threads and not one person with a definitive fix to the issue. I have had tons of people tell me try this or do that. I see in the threads that some have tried with no success. Has anyone figured out the issue, or is everyone giving up on the cars and junking them? This car is still in good shape but my wife will not drive it as it is a hazard on the roadways with this stalling issue.
Any help would be appreciated.

 

I'm new to this forum and the original owner of my 2013 malibu 2LT 2.5L. It started stalling occasionally around 80k mi. and I had to shift to neutral at almost every stoplight. I've always monitored and changed my oil myself for the last 40 yrs. Currently, I maintain the 2.5L engine oil level at the very top of the level recommend range of the dipstick. That solved the issue and it's my daily driver currently having 197k mi. Also, this engine burns a little oil and if the it gets mid-way on the dipstick, it will begin the stalling behavior again. I hope this helps.

 

I am a mobile automotive diagnostician, and I often fix the problems that shops couldn't figure out (as well as some that they create).

The primary cause of this issue on this vehicle is the intake manifold bolts coming loose. This can be confirmed by checking the fuel trims in the live data (combined fuel trims >10 at idle) or by physically checking the intake manifold for any kind of looseness.

Another potential cause that is very uncommon is loose cam cap bolts. This can be checked by removing the valve/can cover and checking the cam cam bolts for tightness. It will be obvious right away if this is your problem.

Other potential causes are going to be general failures that should be diagnosed by a competent automotive technician.
