I've discovered that the old HOV bug in FSD still exists in V12, and it's actually nastier than in V11. The problem arises when the vehicle is in FSD on a freeway, a route has been mapped involving a right lane exit, and the vehicle is moving in an HOV lane on the left with a single-white-line...

I'm becoming a fan of V12 with 12.3.4. I've seen some very interesting and positive behaviors, like correctly selecting when to pass on waiting for a pedestrian to cross the street and when to stop & wait. Today, I witnessed a really amazing behavior. I had FSD engaged on a major multilane...

I got 12.3.4 last night and gave it a quick try this morning to a local Starbucks. It did well on my little side road (not speeding but going a bit slow), then made a great unprotected left turn onto a main 2-lane road. It then strayed over the double yellow center line and showed no intention...

After my last Tesla SC visit, the tech left a bunch of vehicle errors in the Service mode listing from when he fixed the vehicle. They’re now old meaningless errors, but they persist in the display nevertheless. Is there any way for me to purge those errors from the listing myself? Do I have...

I’ve noticed recently that I hear a clicking noise from my left rear wheel when going thru a drive-thru lane. It only happens at very low speed and is synchronized with the tire rotation. Looking around TMC, I see discussions about this problem with M3 and MS, but no mention of this with MX...

2017 MX, running 2023.44.30.14 I thought Service mode offers a HV battery health test under the HV System tab, but I don't see it. I just ran my battery down to 17% after a trip, then went to the Service menu & found no access to the test. Is this feature only for newer vehicles? A different...

Tesla launched its own car insurance. These drivers say it's a lemon.

I’m looking at Teslafi, and it appears that the most recent firmware releases include FSD 11.4.4, not 11.4.7. I’m interpreting this as Tesla has abandoned 11.4.7 and regressed to 11.4.4. They apparently see 11.4.7 as a dead end. I’ve been waiting for fixes to the problems introduced with...

I just bled the brakes on my 2017 MX using a Motive Products (Motive Products - One Man Bleeder & Filler Products) pressure bleeder. 85K miles. Fluid tested as having a bit of water in it but not excessive, and the fluid was dark. This is a fairly easy job with the right tools. One problem...

Lots of negative reviews of service centers, so I thought I'd throw this out. My wife ran her key fob thru the wash, and it quit. (Side gripe: why the hell aren't they waterproof???) I called the Renton WA service center parts, and someone actually picked up the phone and helped. They had...

Since I received 2023.7.30, I've lost Autowiper functionality, and it's VERY annoying after all the years of Autowipers not working, then working poorly, then finally working reasonably well as the many firmware updates flowed out of Tesla. I've called the nationwide support number and have...

Got 11.4.7 last night & went for a test drive today. Had 11.4.4 before. 11.4.7 failed three times in 2 miles or less. Why bother with updates? 1) First failure was at a construction zone in which traffic was running one-way with flaggers, and my lane was moved to the left lane. The vehicle...

My upper control arms are getting very squeaky after only a year since Tesla replaced them at my expense. The service center told me today it’s unlikely Tesla will pay for the new ones since it’s 13 months since the replacement. They’re only warrantied for one year. I’m wondering if anyone...

We took a trip today that included a Supercharger session in the middle of the planned trip. Nav showed that we only needed to spend 10 minutes charging to reach our destination with a 20% reserve. Normally, we get out, use bathrooms, find a snack and go for a brief walk. & just let the car...

I reattached a rear bumper USS today with superglue and dowels thru the towing hitch hatch. I could not reach up thru the trailer hitch hatch because the space was too tight. I tried to take the cover off below the bumper cover, but I discovered that the back edge snaps into the bumper cover...

Testing FSD beta 11.4.2 today on a short torture course that caused problems for earlier versions. This drive was done in Chill mode. At 5:49, it barely made the transition into a left turn lane to enter an onramp to I-5, which earlier versions could not do. It had to make a hard braking...

The process “hold fully up on turn signal stalk + brake + key for 10 second” doesn’t unlock the gateway. I’ve got the key in the vehicle & placed on the center console below the cup holder. What am I doing wrong?

Found the following today: This after Elon steadfastly refused to advertise. I wonder if Tesla is now paying for these ads. Elon is desperate for Twitter income.

Drove about two miles on 11.3.6 today. It still stops on a busy road for no reason (no signs, no traffic lights). On a left turn at a busy intersection with traffic lights, it did a messy, abrupt move into the left turn lane, then moved into the intersection for the turn & wouldn’t make the...

Do we start giving the software creativity points for re-routing? It certainly doesn’t get many performance points, except that it did follow the traffic cone re-route. All it had to do was just keep going and move back into the right lane after the construction site. It did a pretty good...

I'm done for the time being with trying out FSD beta 11.3.3, especially after the rather dangerous interaction turning left into two oncoming vehicles. I know others have had a lot of luck in urban environments with this build, particularly with left turns, but my experience is quite the...

I just uploaded a video to YouTube of today's adventures: The HOV lane problem is a new issue, as far as I can recall. Nav on Autopilot was able to get out of an HOV lane to take a route-planned exit. I will be posting more problem videos. Seemingly, FSD beta misbehaves in my area a lot...

I discovered that the driver front door seal on the body has split at the bottom. How difficult is this deal to replace? I’ve tried calling two Tesla SC’s parts departments and left messages. No response. I’m not very happy that I have to actually visit one to get part info.

Took a drive today from south of Seattle to Snoqualmie Pass and back, on both city streets and freeways. Overall, I saw some behaviors that are better than prior FSD beta versions, but some that really need work: 1) This version DOES NOT recognize emergency vehicles with lights on. I was on...

My charge port has started malfunctioning (no lights, slow to allow charger connector to engage, etc). Does the CCS upgrade include changing out the charge connector?

I’ve found that FSD Beta (under 2022.44.30.5) cannot negotiate a particular intersection geometry shown below. The vehicle just stops before the intersection and will not proceed. Here’s the setup: the vehicle is in blue with the direction of motion shown by a black arrow. The planned path...

Based on stories on Teslafi, it’s supposed to be single-stack, but is it really? I’ve been hoping for some serious upgrades to NoA, i.e., the highway stack.

Got into Service mode for the first time today, and discovered the following DAS errors. I also found a DAS reset feature in one of the sub-menus. 1) What is DAS? 2) Should I perform the DAS reset to clear these errors?

I can’t get a straight answer to this question from Tesla sources, either the nationwide support phone folks or local service center. It seems odd that Tesla would now include that capability under the Service menu unless they thought it was needed for us to perform more than once in the life...

I found this part in the mid-seat area on the floor of my MX. Does anyone know where it goes? It isn't for the seat controls. Some trim part?

I’ve started having problems recently with plugging in my Tesla wall charger to my MX. The latching mechanism tries and fails to engage the notch in the charger connector. I get an orange ring on the receptacle and a warning on my Apple Watch that the charging connector has failed to connect...

Two months ago, I had the upper control arms replaced for the second time in the vehicle’s history. In both cases, the front end was very noisy, and the new control arms apparently fixed the problems. Two weeks ago, the front suspension began squeaking and creaking like hell again. It was...

First one was in 2019 under warranty, thus one cost $628. I asked if these are now “consumable items” & got no response. The new ones’ part numbers have an “F” suffix. Started squeaking about a week ago.

I’ve been periodically nagging Tesla about the free FSD camera upgrade for my 2017 MX since last year. I’d set up a service appointment that was later canceled by the SC because they didn’t have the parts. I was told repeatedly that I’d be notified when the parts were available. This time I...

My 2017 MX has developed a quiet but annoying ticking sound on the driver's side that is tied to the HVAC system. It seems to be directly tied to the airflow direction controls (up, out, down), not the fan. The noise can be turned off and on by turning off the airflow out of the dash vents in...

Many may have seen Elon's recent tweet informing those of us with older (2016-2017) model X and S vehicles that we won't get FSD Beta because our AP cameras are out of date. He also tweeted that Tesla would provide us with a free camera update. Having HW3 doesn't matter. I called the...

I just finished installing Unplugged Performance rear adjustable camber links on my MX, and it ended up as a multi-day effort with more work involved than I anticipated from the “instructions” available. I thought I’d document what happened so that others interested in doing the same job can be...

I just installed Unplugged Performance adjustable camber links in the rear suspension of my MX. The bushing bolts are supposed to be torqued to spec with the suspension at ride height, which I accomplished by jacking up the rear hubs until they were at the same distance from the top of the...

I had the every-two-year A/C maintenance done today to replace the receiver dryer and desiccant. First time done in four years of ownership, so overdue. I wasn't having any A/C problems. The service wasn't very expensive, $285, given that the A/C system has to be emptied and refilled in the...

I’m putting in adjustable rear camber links. What is the best camber angle setting? I’ve seen one link vendor claim -1.0 deg instead of the standard -1.7 deg.

Somewhere within the last few months, I thought I saw something on-line that suggested we should be able to record video from six cameras (front, back, both fenders, both B-pillars). I'm getting four (front, back, both front fenders). I called Tesla support yesterday, and after some time in...

In the process of making this, I learned some things about how Tesla manages the 12V battery charge state. At this point, it appears that the vehicle may not charge the 12V battery if the main battery level falls to 44%. I'd have to do some further testing to try observing what the 12V battery...

This morning, I was greeted with a completely blank, dead MCU1. It had been working fine but sluggish yesterday, but two-scroll-wheel reboots have been taking more than two minutes before today. I tried the reboot this morning, gave it three minutes and gave up. The vehicle took 1-2 minutes...

I'm on 2020.24.6.4. Got a deflating left front tire Monday, got the vehicle home & had the tire repaired. The TPMS low-pressure warning message came up on the driver display. After getting the tire fixed & properly inflated, the manual states that one needs to drive for > 10 minutes to...

I'm a noob to the Dashcam feature under HW3, and I've noticed some apparent problems with recorded video quality. I've attached an example below. It exhibits hesitations and image break-ups. This is one of the worst examples - the distortion problems aren't this bad on all recorded video...

AP 2.0 on 2019.12.5. The sign showed up at the very last moment while on autopilot - I was trying to let the car react to a T-intersection, and I hit the brakes when I realized it wasn’t stopping itself for the intersection. No traffic light, just stop signs.

They make people crazy, including me. Here's how I fixed mine: Note that this works on any vehicle, not just Teslas. It does help that the wiper arms have a flat cross-section.

My right front fender camera has developed a new quirk in January 2020, in that I get a dashboard message that the camera has become obscured or stopped working while I'm driving in moderate to heavy rain on freeways. The problem seems to take a half-hour to an hour to appear. When I stop and...

I tried the parking lights for the first time when parking on the side of a dark, winding, wooded road at night. I wanted to avoid getting hit by someone. Unfortunately, they went off as soon as I got out to leave. Sucks. I called Tesla today, and they gave me a trick: get out of the...

I just finished installing the 80 amp wall charger in my carport. It’s on a 50 A circuit with a NEMA 14-50 outlet that I have been using with my mobile charger. I used the top power feed plate with its own interconnect wires to the charger. I noticed that the interconnect wires seem to swivel...
