Acceleration Reduced.... new problem

[Knightowl]

Just got this error today while my wife is driving back from iowa across nebraska with the tesla 63,790miles, Feb 2014 build S85 battery revision D. Already have and annual maintance scheduled for this Sat so just adding it to the list, left my service center a voicemail on it.

My turn. Happened yesterday. 38k miles on a 4 yr old P85. Am taking it in tomorrow for the contractor replacement.

In the interest of accuracy, especially since you write books about Tesla, the word is contactor not contractor. A contractor builds houses.

Autocorrect. :-(

Me too! Got the message today, 2013 P85+ with a B pack, 44k Miles.

My car has always had the 'balloon squeal' on aggressive acceleration, looks like replacing the contactors eliminates this noise as well?
Has anyone experienced the same issue with the new/updated parts?

It did? Actually the contactor should not make any sound, if properly working, or not. Especially no balloon squeal.

Yea, Tesla doesn't seem too eager to replace the contactors/switch just based on the noise alone, but it definitely seems to be a common occurrence.

How much balloon noise is acceptable

Yes, after mine was replaced I no longer had any baloon squeel on hard acceleration. Already been 10k miles since it was replaced now.

 

[Stephen4]

Yup, me too. No squeal after my contactors were replaced...and that was over a year ago now.

I got the same warning light acceleration reduced last week after 38 k miles on it.
Now it is fixed and uckily, It is covered by the battery warranty.

What was the fix?

 

[ShibbyRomes]

Happened to me yesterday. I dont believe it has to do with supercharging as I have not supercharged in a while. Tesla Ownership also mentioned "never seeing this". Weird since I think the original post was over 2 years ago. Anyhow, 2013 S85 46k miles. Luckily (or unluckily) I had an appointment to fix leaking sunroof (again). Dropping it off in 2 days.

9/22/18 8:45pm merging onto freeway and error popped up "Acceleration reduced - Contact Tesla Service when convenient". @ 26,830 mi, 2013 P85 12XXX, original battery (A pack?). Appreciate the other posts so I know what to expect. Car seemed to have gotten louder in last 7k miles, especially at highway speeds (likely during "fun" starts too).

Not sure what went wrong. I got in the car in the evening got a screen full of errors. Set up an appointment with the SC next week soonest available time on the app but not sure if it is even safe to drive.

Multiple errors are likely caused by a corroded or broken ground connection.

This error has to do with the connection to the main battery.
Here is my write up.

New Battery Connections

Most of these error messages seem to be coming from 2013 vehicles (there is one 2014 owner reporting the issue). Does anyone know when they changed production to the new contactor?

Got the message today. Scheduled service.

2015, 70D, 83k miles, I'm on my 2nd HV battery

I guess the photo didn't upload, here it is again.

Scheduled service for next week, they texted me and said to come in today.

 

[tjdog800]

This message popped up on my '16 Model X. Service already scheduled 10 days out. We'll see if that remains OK.

Well mine turned out to be the battery heater... not covered by the battery warranty, obviously.

Sometimes I hate this car.
