Another rear inverter failure ( UI_a006 )

[OG_Cyber_]

Might be helpful and might just save your life…read on…2 days ago, truck alerts for required service (code UI_a006). Code didn’t provide much info and all i could do was schedule a service appointment (which was 2 weeks out). Continued to drive the truck and approximately 18 miles later, boom, the pyro fuse for the rear inverter blows sending the truck in a hard jerk. The truck immediately stopped and would not move. This was extremely dangerous, as I was in the fast lane of a 45mph road at 5:30am (still dark). After trying to get the truck to respond it decided to simply shutdown and become unresponsive (even killing the hazard lights). I had to get out using the manual door handle override and get to the side of the street and watch car after car almost rear end the truck. Rounded up some traffic cones, threw a flashlight out on them and continued to hope to avoid disaster. Tow truck finally arrived 25 minutes later and had to snatch the truck from the lane of traffic and we were on our way to the SC. Of course the SC said this has become super common on these CTs and they would have it fixed within a few days. We will see… So, if you have a dual motor and have yet to experience this, carry flashlights, flares, or something in case this happens at night to you. This one was tough because i was not allowed to use the front motor to drive it at limited speeds which has been widely reported.

So sorry this happened to you. Scary for sure. Glad you are ok.

"Super common" that seems like a pretty massive issue...

Is this after using the rear bed outlets for a while ? Damn scary for sure.

Bed outlets are unrelated. This is the inverter for the rear drive motor

Planning a 1200 mile trip up north very soon. Now I'm nervous. I have a service appointment in two weeks for unavailable suspension adjustment (stuck in low), should I request inverter replacement?

Yeah this must be common because mine went out 2 weeks ago and my SC already had the part on hand to replace.

What was your experience? Did you have time to make it into the SC after it threw the error?

Was on the freeway and felt a clunk like others have said and it immediately threw up the "DI_a139 Rear motor disabled - OK to drive" alert. Took it into the service center the next day and picked it up about 4 days later.

My inverter failed and was replaced on October 3rd. Tesla released a service bulletin on October 4th addressing the inverter issue. I made a service appointment on Nov. 18th for a minor issue, and Tesla now added the inverter to be replaced on certain CTs. Since my inverter was just replaced, most likely Tesla will not replace mine, but they'll ensure I have the newest inverter. People who are concerned about their inverter failing before a long road trip, stop by a service center and ask them to run your VIN to see if you have any pending service bulletins for your CT.

Several have tried and were unsuccessful. Maybe this has changed with this being more and more common. With the level of danger involved, one would think this would be accepted if requested. I’m out on roadtrips often and just happened to be in the local area heading out out town and 16 miles into the trip it went down. Once I get it back I will definitely feel more confident on road trips. Never hurts to ask and mention this case because only a few of us actually got fully disabled in traffic. Most still had the front motor to allow then to continue driving at a lower speed
