Break In

Break In

Had lunch with a bunch of old friends, who love to rag on me about forthcoming Tesla S. They asked how do you break in a Tesla? (all laughed). We all remember how we broke in rings, valves, pistons and cams, but it did make me think. Does anything need a break in such as bearings or seals, etc? Any reason to keep it under 75 for the first mile or so? Old geezers want to know...

No break-in required.

Kleist | November 19, 2013

Here is the break-in procedure
- drive it as often as your time allows
- drive as fast as the law allows
- make sure you have no car in front at the stop light and make a good get away
- volunteer to run errants
- play with the features while not driving
- do that for at least one to three month and hope that you will be broken in.
Good luck.

Just remember this...There's no warm-up either. Unless you're talking about the tires. Pedal-to-the-metal. :)

This -- the entire lack of engine warm-up -- was my main motivation for even starting to consider an EV in the first place, as my 4-mile (one way) commute was quickly destroying my previous car's ICE because the oil never got up to operating temp and sludge accumulated quickly.

Does the regen need braking in?

cfOH | November 19, 2013

No, nothing needs breaking in. I think the factory rotors and pads are already bedded on the brakes (not breaks), so it should be good to go at 100% from the moment you get in every time.

I spent the weekend at an old friend's house. In the morning she slipped on her shoes and mumbled, "Time to go out and warm up the car..." She then shot upright and said, "I bet you don't have to do that either!" We had a good laugh. Tesla might have a new customer too.

I thought breaking in a car had gone extinct in the 1990s.

You break in the MS by driving it like you stole it!!!

Captain Ducman | November 20, 2013

I took delivery ~a week ago, my MS had exactly 16miles on her. the energy graph was insanely high... in the 800s if I recall. The DS said it is the "burn in" of the motor.

Then I read the post about the Service Center and the crazy energy graph and the explanation being all the high draw item running at once... so, Im not sure about break in per se.

My wife flew up to Newark and we drove to the Damien, CT Supercharger and back. We put ~150 miles on the car. We had the 60mph hum that has been posted and well documented. Tesla replaced the entire drive unit. I am picking it back up tomorrow, curious to see if it has the "burn in" on the energy graph.

Major road trip starting Saturday, I hope she's broke-in, doesn't get broke in or broken.

My break in procedure, Hammer it.
During "break in" my energy graph looked like a two year old child drawing a picture of lawn grass. | November 20, 2013

@Captain Ducman "my MS had exactly 16 miles on her. the energy graph was insanely high... in the 800s ".

This is expected. On the factory tour they show the cars being run on the dynamometer at the car's extremes to confirm the car is working correctly. They also run every car on an outside test track before delivery. These stress tests help ensure the car is performing as designed and weed out any problems before it's delivered.

P.S. Congratulations on your new car!

Actually it's my understanding that in very cold weather the battery does need time to warm up when first getting in the car before it operates normally. Correct me if I'm wrong.

Bighorn | November 20, 2013

My energy consumption skyrocketed today after sitting outdoors for six hours with temps in the high teens. Driving into work beforehand from a 50 degree garage, I was at 275Wh/m, but in battery warming mode with heat on I was using approx 800Wh/m.

Good one ;-)

The car does not need to break in. The driver need. First you need to get confortable with instant acceleration and driving with one pedal!

crazybrit | November 20, 2013

I bought an ex loner car. Managed to get a good deal on it. Anyway, they reset the car's memory when I took delivery (after I had a chance to see it and play with it). When I drove off the "lot" I got the super high spike in energy consumption too. Nothing to do with anything physical. I think it is a divide by zero in the algorithm that takes the kw/m to infinity (miles are initially 0). After a few miles, it dropped to the right level.

@Eleonor2002: You mean maybe it should break in like a Sonicare toothbrush? In order to not surprise a new buyer, it slowly works up to full power over a few days ;-)

elguapo | November 20, 2013

@bronto In cold temps, the battery does need to warm up, but that only means you don't have full regen until it's warm. You can still go crazy fast.

Bighorn | November 20, 2013

I saw limited output as well as regen today. It took well over 30 minutes to have no impediments.

Captain_Zap | November 20, 2013


Wait until Brian H sees "ex loner car".

Oh, the possibilities...

crazybrit | November 20, 2013

@Captain_zap: huh?

robert | November 20, 2013

We have a thought/spelling/grammatical/factual Police in this Forum. He is constantly wasting everybody's time by making corrections to others' posts. You wrote "loner" while meaning "Loaner".

You'll see...

A newlywed car?

Velo1 | November 21, 2013

Just remember to change the oil after the first 100 miles, as there may be small filings, burrs, and other debris from the engine manufacturing and assembly. Also, there may be flakes of metal in the engine oil which is a completely normal phenomenon that occurs within first 100 miles or so as the rings, camshaft, lifters and bearings burnish their respective mating surfaces. No wait, that in only for an ICE car. Sorry if I alarmed you, so feel free to just get in your new baby and drive like you stole it.
