Munro & Associates didn’t begin the 2021 Tesla Model 3 teardown but, however we have already got two movies with the automotive that can educate us extra about how the Model 3 developed since Sandy Munro’s crew first disassembled it. On this second video, he talks about bolts, nuts, and an entry cowl that apparently has no objective, however about which we already wrote right here.

The bolts and nuts inspection was motivated by the complaints that some Tesla vehicles miss them in the suspension. Munro checked in the event that they have been all in place, and so they have been, which isn’t correctly a reduction. The bolts and nuts were missing in vehicles with more use, and some were just loose. In different phrases, the problem appears to be associated to poor torque when putting these components, not somebody forgetting to place them in place.

There are some components within the underbody that appear to have been missed within the meeting course of, however that was a cost-cutting measure, in line with Munro. These components have been push nuts that Tesla found that weren’t even wanted within the first place – so it will have determined to not use them anymore.

Sandy Munro then explains why that could be a good factor for the producer. Just a few bolts much less right here and there can signify fairly a good sum of money saved in a single yr of manufacturing. Prolong that for as a lot because the automotive is produced, and you could possibly finally save hundreds of thousands – not in Munro’s instance, however the automotive trade has “bean counters” for a motive.

We would not have to say that the engineer is pleased to see Tesla is saving cash with these pointless push nuts. The apparently pointless entry cowl within the rear bumper is one thing he didn’t take as simply. He discovered no motive to have it there if the Mannequin 3 has no towing bundle.

What Munro doesn’t appear to know is that the Model 3 rear bumper had multiple situations of falling off the car, particularly after working by water or puddles on the street. We wrote about that on October 20, 2020, and advised our readers in regards to the Tesla Service Bulletin SB-20-12-003. 

Revealed on July 31, 2020, it stated that if automobiles with indicators of the problem confirmed up at Tesla Service Facilities, technicians ought to “change the rear fascia diffuser with one which has a lined opening for a tow hitch (with improved wade efficiency), ensure that the automobile is provided with the up to date entrance aero defend (1104312-00-B or later) and mid aero defend (1104313-00-B or later), and change or restore another part that was broken as obligatory.”

We’ll warn Munro about these two conditions. If he may test if the suspension bolts have been correctly tightened, that can assist make clear the lacking bolts and nuts – those that actually make a distinction. If he can warn his readers in regards to the “higher wade efficiency” of the entry cowl, that can even be nice.
