New 2021 M3P - Coolant low warning

[Dknighter]

Hey, I collected my M3P on Monday and today I got in the car to see a "coolant low - contact tesla services" warning. There is also what looks like a leak under the car. I tried to contact the services by phone but was put on hold for over an hour so I've assumed they are not working today or the next few days.

I can report this in the app however the only options I get is to go to a service centre 80 miles away on new years eve. I assume if there is a leak I shouldn't drive the car at all so does anyone know what I should do in this situation?

I am in the UK.

Any help would be much appreciated.

I wouldn’t drive it unless Tesla specifically tell you it’s fine
Could be for heater or battery or motor (guessing)
Keep trying call center

I have moved it to a new spot on my drive way to see if the "leak" appears again. I am parked facing down on a hill and it's quite cold at the moment so it could potentially be a sensor issue.

Apart from that I'm not touching it until I get an answer from Tesla. I will try again over the next few days and will see what happens.

Did you check the coolant reservoir in the frunk? If empty, then you definitely have a leak. I'd start there, if you suspect a bad sensor. Good luck.

I've been talking to some others and it looks like the "leak" was just condensation and nothing to worry about. It just seems the car was delivered with low coolant.

Use the app and submit a request for roadside assistance. In the description, ask if it’s safe to drive the car. Make sure you quote the error verbatim. If it’s not safe, they will send you a tow truck.

Maybe.

Or you have a leak.

Add coolant to the 'full' line and check tomorrow. Be leery about using the car until it is blessed by Tesla. You do not want overheated electronics.

I sat in the garage with my M3 for about an hour today and noticed a puddle of water under the car, is this normal?

If the coolant is leaking the fluid will be blue. My brand new M3 leaked coolant on day 3 of ownership. As I live far from a service center, they first sent a mobile tech to check it out, which wasted time. It got bad enough that when driving the car limited speed/power to protect the battery. They eventually towed my car to the nearest service center (3 hours away) to fix it. My leak was due to a faulty superbottle which they replaced. If it is a coolant leak, demand a tow, don't drive it there because who knows if the car will make it that far.

 

[Dknighter]

Just checked the car again and it is definitely leaking coolant now. I wiped it and it's blue and leaking all over my driveway. I've reported it for a service on the app but due to the time of year I'm not sure when someone will look at it.

Is it better for me to call roadside assistance or wait?

 

[SageBrush]

One way or another, but prevent the reservoir from emptying by adding fluid as needed. You do not want air in the system

 

[Jstro003]

Call roadside as that might expedite things. It's what I did. Unless you absolutely had to, I also wouldn't drive the car because you will eventually get to the point where the car will limit power/won't let you drive if it gets low enough.

 

[Dknighter]

The warning in the car says "low coolant - OK to drive. Contact Tesla Services" so I'm assuming it's not too low. I have no need to drive it soon anyway.

 

[Jstro003]

Having a major system problem early on is a big disappointment. But they prioritized my repair and did it quickly (3-5 days due to waiting for part). Since that initial repair, I haven't had a problem since. Still love the car and still recommend it to others. Good luck.

Update:

Tesla roadside assistance picked my car up this morning after calling them last night and had it in the service centre workshop a couple of hours later. They have confirmed it was leaking and have told me they will have it fixed next week as they need to order in a part. They have also told me they will deliver it back to my House as the centre is over 2 hours away.

So it's all getting sorted!

I too have a coolant leak (Mod X, less than 4000 miles). Can I add any typical auto coolant?

Not just any coolant, it has to be G-48 coolant. But you can find it at any auto parts store because other car makes use the same coolant. See here for one brand example Valvoline™ Zerex™ G-48™ : Product Catalog - Valvoline

 

[lolder]

I would be hesitant about adding any coolant yourself. Are you sure you have a leak and do you have an on screen warning. If so contact Tesla mobile service.

ALL vehicles with coolant will need topping off when new, since there will always be air in the system. I checked the 2021 M3 LR with less than 10 miles on the clock, and level was slightly below MIN, so I topped it off with Honda pre-mixed 50/50 coolant, since Tesla coolant is also blue. Having said that, I could NOT engage the clips in the front of the cover (the ones next to the frunk gasket). The plastic is so flimsy that you push the whole thing down, and the clips only partially engage, popping out when pressure is released. So left it alone, since the side ones and upper ones did engage, but wasn't thrilled about that. Ha ha. Oh, and there was one plug missing, so next time I remove the cover, will relocate one of the few that don't engage.

Can one add coolant on our own or is there a special way so air does not enter the system?
