MCU reliability issue

[AC DC]

Took my car in for a routine checkup mid September, nothing wrong with it just a one year service. Whilst at the service centre Tesla did a software upgrade and when my wife went to pick it up it would not move/activate. After two frustrating weeks of no car and little information or satisfactory follow up from Tesla service centre they finally decided it was the MCU (Media Control Unit). In actual fact it sounded like they had no idea and referred back to USA for tech support. My guess is they somehow bricked the original unit but Tesla tried to casually pass it off as saying it was 'just a coincidence'. MCU was replaced but then took several days of reinstalling before it would work. Finally got it back and working.

Anyone had similar issues?

Also just the last few days the driver door handle will present but cannot open the door. Sooo, back to Tesla service centre first thing tomorrow..

Sorry to hear that Geez sounds like exactly what happened to my Ducati Multistrada that I had for 4 months before I sold it; brought it in for oil change and they updated the software. Then the bike won't turn off unless they pull the battery cause the keyless ignition switch doesn't work any more. A week on a courtesy bike and got it back with a new ignition module. Then the active suspension wasn't working and was like riding a pogo strick with no damping. Another week and they got a software pack from Italy since whatever they did to fi the ignition wasn't working well with the suspension control unit! Then.... The night I get it back, the menu and signal button fell off while I was riding and I had to draw the line....

It sounds like on a car with so many electronics that once something is changed it has a domino effect on other parts of the car? But I hope under warranty they will eventually replace everything! However I'd be pissed off if they don't give me a loaner car for two weeks or pay for my taxi to work and my family.

I might see you there lol I just got mine and the windshield washer isn't working.....

I did annual service just couple of weeks ago, I had firmware upgrade done on it as well, all went well. I'm surprised that they informed you to go pick up the car without first checking that everything went smoothly. I think that particular guy who handled your case didn't do a good job.

I would be very pissed off if I didn't get a loaner in your case, it was 2 weeks not 2 days, even 2 days I can't tolerate! I do 80km+ commute everyday!

After every service visit you'll be asked via email to fill out a quality survey, if you didn't give them good enough scores you'll get phone calls. Someone will get more details of your dissatisfaction. I guess that sort of comments will go straight to HQ as Tesla is very concerned about user experience and service quality.

Thanks for your reply 3fiftynine, I am of the strong opinion that my case was not handled well! I did get a loaner which helped (though surprisingly that car had some sort of issue with vibration coming through the steering wheel at certain speeds). I also filled in the survey with low scores but no one has called me to date.

Took the car in today in the hope of getting my driver door handle replaced but they don't have stock until next month. No loan car was offered. Just to quantify what a hassle this is I now need to enter the car from one of the other doors and clamber over. Try it yourself and see just how inelegant that looks!

Are you sure that wasn't the lane assist warning enabled? Works pretty poorly in Hong Kong, due to the poor lane markings. It is supposed to slightly vibrate the wheel if you change lanes without indicating, but here in Hong Kong it seems to vibrate every few minutes.

Yes, I got that too time to time even though I wasn't leaving my lane; ended up just turning it off
