Hello from the UK!

Wondering if one of you knowledgeable people can help me? I have a 2019 EC (in red - very nice!) that I bought 3 weeks ago (from a dealership that is 200+ miles away from me (long story)) It has been fine until today when I went to go out and it wouldn't start. The lights flashed and it made a juddering sound and then that was it. It did connect to my phone and start playing my music.

I called Mitsi Assist and they sent out a very nice man who told me the battery was flat and that it had probably been standing on a forecourt for some time before I bought it. He got it going and told me to go to my local Mitsi dealership and get it checked, which I did.

They say there is nothing wrong with the battery.

On the drive home the ASG was working and I realised that it has not been working for at least 10 days (only really thought about it when it shut off and I panicked I had stalled or the battery had failed.)

When I got home I called Mitsi customer services and explained all of this and they said to phone the dealership back and tell them about the ASG starting working again.

Haven't done that yet - thought I'd come on here instead and see if anyone knew anything or had any bright ideas.

Right now I'm feeling a little deflated and wondering why I spent £16K on this car - which is a shame because until today I LOVED it - now I feel like I can't trust it which is not what I was planning from such a new car.

Any ideas?

Thanks! If you made it this far - well done

Sarah, first let me say I am SOOOOO glad Mitsubishi did NOT put ASG on their vehicles in the U.S. My wife's Jeep has it and it's incredibly annoying.

So anyway ... there are a few things at play here. First is that a battery might have enough charge to flash the lights and turn the engine over and still not start it. If the jump from the service guy got your car to start right up, the smart money would be on the battery. Next, the ASG (auto stop/go < what a stupid name) system is only supposed to stop the engine when your foot is on the brake AND the battery has sufficient charge. If the car has not yet warmed up, has a large electrical load like the A/C is on, or the battery has a low voltage condition, it will not engage. Finally, when you disconnect a battery from a modern car for more than a few seconds, it reboots all the electronics, so things that previously might not have been working get reset.

If your local dealership tested the battery and it was okay, then it could have been something as simple as a loose or dirty battery connection at the terminal. Simply by disconnecting the battery to check it might have fixed the problem. Quick question ... when you went to the dealer, did they charge the battery?

I guess the only thing you can do is see if it happens again. If it does, then the battery and/or the alternator might be defective.

My money is on a dud battery or it was, as suggested by the service guy, sitting on the forecourt for too long without a start. I have a new pick-up/ute which we only use for work stuff around our farm. It is under 6 months old. Got in it one day after a prolonged period of non use and it failed to start. Jump started it OK and then put it on a 7 stage battery charger for 24 hours and it has worked fine since. I had to rest the Check Engine light with an OBD II tool as its has logged a voltage system low error in the ECU. Easily cleared with the OBD II tool.

I also carry a quick started kit in both cars for a quick start if there is a battery issue. ASG didn't make it to Australia either, thankfully.

Thanks for the input guys - yes - I'm beginning to think that the ASG is a pain in the butt. Thankfully(!!) it has stopped working again - went out in it last night and this morning and the car did start but ASG not working so I reckon the battery is low again.

When I took it to the dealer they didn't charge it - just tested it and said it was fine. After I posted on here I called them back and told them about the ASG starting to work again and he said that only works when the battery is at least 75% charged, so evidntly it wasn't again last night or this morning.

I guess I have two choices - wait for it to happen again or just bite the bullet and pay for a new battery myself.

I generally would replace my battery every 2 to 3 years. I hate hearing that slow, laboring crank when it gets cold for the first time. While I would consider an OEM battery in a a 2019 to still be in its prime, if a lead/acid battery cycles from a deep discharge to fully charged it could damage one of the cells yielding a permanent low voltage condition. The tester should have found that, but the fact that you drove it to the dealer might have put just enough charge on the battery to fool the tester.

The other thing you might ask them to check is battery drain when the car is off. All cars will draw some current to keep the electronics active, but it should be below a certain threshold or your battery will go flat in no time.

 

[MopTop]

Yes, I did wonder if driving it there made a difference to the battery.

If it happens again will ask them to do a "drain" check and see what they say.

Im with Lunatic59, I always make it a point to replace the battery on my cars every 2 years. 3 is pushing it. Even if it still seems to crank and fire up just fine.

It might be a battery drain of some sort. I know my brother's 3G Acura TL was notorious for draining the battery just to power the bluetooth even when the car is off. so its worth a check too.

Take out engine start/stop function switch,put tape around the switch,engine start/stop function is always disabled even after restarting the engine.
Worked on my Eclipse Cross
So no more annoying engine cutting during stopping at a red light for example.

Hi Zarbs,
Nice explaining story. Thanks. What kind of OBDII tool are you using?
