Steering harness plug was corroded

I don't know. Go for it I don't work around high voltage.

Mine was a 2018. 51k miles. $4200 to replace the steering and front harness.

At least he has a warranty. Mine went out before I had the issue.

Don't drive through water. $4200. Had to replace wiring harness in front.

Ok, so I just got word from Tesla that the wiring harness is corroded and the steering rack will be replaced, along with an alignment. $3200. Here are the pics of the wiring. This car just turned 5 years old.

One reason I thought it was overloaded CPU is there would be stuttering in the reverse camera. I have it at Tesla today and will let y'all know what they find (hasn't happened for a week!). Had the appointment 2 weeks though and they saw all the errors in their logs.

The issue started for.me in March.

So did replacing this fix the problem completely? I am having the same issues.

I'm starting to think this is a problem I cannot solve externally. I'm very tempted to get off the Beta, as I think Tesla Vision started all this.

If your phone is paired via Bluetooth remove the connection (just disconnect, you don't have to unpair it). Also don't remove the key, it's just something that interferes in the steering software via Bluetooth.

Tonight I was listening to the 2023Q2 stock results and we were going out to dinner so I pulled up my phone and got it playing on Youtube. When I got into the car I switched to Bluetooth and connected the car to my phone and immediately got a 'Steering Assist reduced' message, not even putting...

Well, I hate answering my own question but here goes! I had 3 appointments at Tesla which I canceled each time because the car would get the Steering Assist errors intermittently. Sometimes I would get it once and after a power cycle it'd go away for a day, sometimes it'd happen several times...

Ok, so a further followup. Reformatting the SSD didn't help. Removed it and still had the problem. Tesla wanted $2770 to replace the steering rack and $215 to do a check first. I had a visit scheduled but have canceled it. I still continued to think this felt like a software error so I...

Have them made. Find a Machine shop or explore online options.

My Model 3 LR AWD is having the same exact problem. It has happened since Tesla Vision was released (I'm on Beta). It also seems to happen switching into reverse, and is accompanied by a THUNK in the steering wheel. I have found if when I switch to reverse if I don't touch the wheel and...

Follow up, drove 75 miles today much of it on autopilot and zero errors.

Not even sure the disk was full. I just know that one thing cleared the errors!

I've been having these issues on my 2018 M3, so I scheduled a service appointment. They want to replace the whole steering rack, $2770. Not going to happen. I decided to try to diagnose it myself. I have 45 years in the computer hardware and software industry, most of it at NASA. First...

Thanks, that was a thought I had also. I had the 12v battery replaced under warranty about 2 years ago so it's likely due. I may try a Lithium auto battery replacement.

I'm in a 2018 M3 LR with Beta Self Drive. A couple of days ago I was parking and was very close to a car and the Steering Assist reduced message came up. I got a strong bump in the steering also, felt like it was trying to take control (I was going less than 1 mph). Got parked, no reduction...
