Tesla Model 3 Quality Control Issues

Jason from Engineering Explained gives a great summary of some of the quality issues with his new Model 3. We considered preordering one last year. Not sure how I would have felt if I had taken delivery and immediately noticed this many defects.

My humble perspective is when Tesla does fix Model 3 issues and provides cockpit interior on par with F30 - including HUD - then perhaps it may be considered a worthy competitor.

Let's start with the "iPad" which doesn't rotate to adjust to driver preferences.

Not even close.

Tesla Quality? Lol. Some parts of our Model S 100D are put together so horribly it looks like it came straight out of a Mirage (then again the Mirage's fit and finish maybe better )

This guy is an engineer? The use of the "plastic" calipers to take gap measurements is a complete joke.

I'd also like to comment on "Quality". W. Edwards Deming is considered the father of modern statistical quality control. He is one of the Americans who the Japanese actually listened to when (re)building the Japanese car industry after World War 2. He defined quality as "fitness for use". I think the purpose of the Tesla Model 3 is to provide the first mass produced electric sedan at a reasonable price rather than a show car with perfect door gaps and panel surface matching. It's obvious the scratches are post manufacturing issues related to the quality of the delivery service and handling of the vehicle. The paint defects are... paint defects, every car has them if you look close enough.

F-3-O, As an engineer for an automaker, I would suggest you are it entirely correct. I have not heard Deming quoted in the past 10 years or so. Quality metrics for automakers absolutely does include fit and finish. I am certain that Tesla has both metrics and assessment related to fit and finish, including panel gaps and alignment.

I have never seen anybody that knew how to use calipers, use them like that. But I suppose for what he's doing horseshoes and hand grenades is close enough. Might as well use a tape measure. (or a yard stick)

+100% They were the wrong type of calipers. The idea was correct, but he should of used dividers rather than a vernier caliper. He was supposedly measuring to the 10th of a millimeter, which unless he has surgeon-level hand steadiness and microscopic vision, the accuracy of his results is at the least, questionable.

I'm not sure where the guy lives but he stated he ordered the Tesla on November 26th and it arrived 3-days later. So much for paying $1,000 deposit to get a manufacturing slot some 30 months ago...

Can you say hype?

My shop manual for my '66 Ford calls for a go-nogo type of tool to measure panel gaps. Digital calipers are obviously more accurate assuming the user knows what he is doing. Somebody needs to show this guy what those pointy things on top are designed to do.

Was the bumper falling off due to flooding roads where water build up dragged deep into the bumper and dislodged it ?

Because those kind of conditions can stall or hydro lock many conventional cars.

No, rain fell on the car accumulating in the bumper, the weight eventually pulled the bumper off. Nothing to do with flooding.

Unacceptable. My guess is that Tesla will replace the car.

Training issue alledegly in the end. Apparently there was an adhesive strip that wasn’t applied to a cloth like shield. So when it rained or you drove through water and the cloth shield failed, water would accumulate in the back of the bumper cover. The weight would then cause it to fall off.

Wait are people here actually defending the atrocious defects and lack of final QA / QC of this POS car by attacking his methods and tools ???

If there was a big piece of dirt or dust in a clear coat of a cheap civic it would have been sent back to the line
Those scratches and paint defects are unacceptable
I've gotten better quality paint from a maaco shop FFS

I'm not defending Tesla. I don't think the guy is wrong about being upset with the QA failures. That one hood gap alone should have disqualified the car from delivery. As far as the paint, well, I have painted a few cars in my time, (not in a tent though) and I know dirt happens. You fix it and you move on. That, like the hood gap, should have been caught and repaired before leaving.

I noticed the apparent lack of knowledge in how a set of calipers should be used, thought that was funny, and pointed it out.

I would be just as mad if I saw such differences in panel gaps in a brand new car. We're not talking about a sub $20k focus base model... it's a tesla which starts at $35k.
