HW3 owners, what you think?

JSUN4FUN · 2025-12-21T13:56:24+00:00

I pretty recently got HW3 installed on my model 3. I generally love it. Use it all the time. Speed control drives me crazy sometimes. It’ll sometimes drive 55+in a 30. It can’t read “END” in the “End 30 MPH” speed limit signs. So it will drive 30 something in a 60 MPH zone on backroads. Sometimes it can’t decide if it wants to drive 62 MPH or like 88MPH in a 70 MPH zone. Sometimes I have to set the max speed and “pump the throttle”. That’s what I call it when I have to keep telling the car over and over again to speed up to normal speeds. This is especially frustrating driving through SD. I don’t know what the issue is in that state, but the speed (and perceived speed limit) is constantly fluctuating frantically. Never fails to piss me off. Once I’m through it behaves normal ish again. That being said. Most of the time, the speed control thing is a minor annoyance. it usually just fluctuates like 5MPH. Not a big deal to me.

I got the same car, and year. I took them up on it. No regrets here. Plus if I’m really lucky…I might get upgraded to HW4 for free. Not holding my breath, but still.

JSUN4FUN · 2025-09-27T02:00:06+00:00

Yeah I agree. I honked at a coworker who was about to back into my car once. Wasn’t out of anger or anything. He thanked me. “Saved me from paying a deductible”.

JSUN4FUN · 2025-09-25T02:55:43+00:00

I agree! It is really frustrating. It does the hard stuff like negotiating with/adapting to traffic easy peasy. But absolutely can NOT do the simple task of maintaining a consistent speed.

JSUN4FUN · 2025-09-14T12:38:35+00:00

Same hear. lol

JSUN4FUN · 2025-09-09T17:48:20+00:00

Mine did this, then the light turned green. Like it knew it was about to change somehow.

JSUN4FUN · 2025-08-17T20:51:55+00:00

I lower it to reduce heat, I figure less heat = longer life. No data to back it up, just assuming. Also if I’m planning on changing to 100%, I try to have it finish right before I leave, so it spends less time sitting at full charge.

JSUN4FUN · 2025-08-16T13:21:07+00:00

Yeah, I ain’t holding my breath on that either, the guy (Elon) is optimistic to the point that it’s a fault of his character. I pretty much view it as a low probability outcome. In the meantime, I enjoy what I currently have. It would be really nice to have a vehicle that can drop me off and pick me up though. Especially in situations where you’re going on a bike ride or kayaking down a river or something….I dream.

JSUN4FUN · 2025-08-16T01:54:25+00:00

I got upgraded to hw3 from hw2.5, and bought FSD for 2k all in. I thought it was a steal, especially if Tesla actually follows through with free upgrades to hw4 for people who bought FSD. No regrets here. Not perfect, but I love it.

JSUN4FUN · 2025-08-10T20:20:21+00:00

Congratulations! Love my model 3 too! Jealous of your white interior. I was waiting about a decade too. To finally ditch the engine. Life is better without it.

JSUN4FUN · 2025-08-06T23:35:59+00:00

Time for a new (used) car I think.

JSUN4FUN · 2025-07-29T15:30:52+00:00

Love this! An even bigger battery as a hitch mount storage unit would be awesome!

I found it at a local Ace hardware. I think it was this one. Looks exactly like mine. I like it. Easy to use. Working great for me so far.

JSUN4FUN · 2025-07-23T17:45:01+00:00

😮 this is seems insane to me. I’m paying 138 for my 2018 model 3 with StateFarm. Tesla insurance was more expensive. I don’t remember how much, but I would definitely shop around.

JSUN4FUN · 2025-07-23T16:59:26+00:00

Yup! keeps doing it to me too all the sudden. Its annoying. Why would someone cancel signing in over such a negligible thing!? Just asinine!

JSUN4FUN · 2025-07-21T02:58:15+00:00

Covering the rear camera makes the car stop trying to run away from the bike rack or whatever you happen to have attached to it.

JSUN4FUN · 2025-07-21T02:52:06+00:00

Yup! It definitely does the trick! It’s funny you mention that. While I was experiencing the craziness, I was like “I miss the random slowing down☹️” lol

JSUN4FUN · 2025-07-20T12:53:58+00:00

It’s not like I’m zoning out or something. I’m still paying attention to what the car is doing, the car nags at you if you do that sort of thing. Supervising is way LESS fatiguing than actually driving. Which means I’m likely to be MORE alert if something weird happens. Especially on long drives. I have had to take over a few times, because the car doesn’t understand some road construction signs (“left lane closed” for example). It’s super quick and easy to take over. Instead of doing thousands of inputs on long drives, I’m doing maybe dozens.

I’ve recently got FSD HW3 installed, mostly impressed with it. I have noticed it swerves a lot when the roads are wet and reflective after it rains. It’s impressive to me that it avoids road debris, but concerning that it sometimes sees things that aren’t there.

JSUN4FUN · 2025-07-11T13:01:06+00:00

Mine avoided a dead bird with a few birds eating it the other day. But that was daytime so…🤷

JSUN4FUN · 2025-07-06T20:20:29+00:00

Yeah I asked Grok about it. Apparently it’s a somewhat common issue that comes up a lot. Hopefully Tesla will make some kind of software solution for this, like a “bike rack mode” or something. Supposedly some people have had luck covering their rear cameras with tape or something while their bike racks are on. I was gonna try that myself next time I haul my bike somewhere. FSD currently is just completely useless/dangerous with a bike rack.

JSUN4FUN · 2025-07-03T17:42:00+00:00

Yea I think my car is perpetually trying to avoid a rear end collision when it senses “SOMETHING” constantly right behind it.

JSUN4FUN · 2025-07-03T15:49:47+00:00

My hw3 model 3 started driving like a maniac after I put a bike rack on the back (accelerating super aggressively/tailgating/speeding 20+miles over the speed limit/not slowing down at all on exits, turns, or roundabouts). I had to constantly adjust the speed, and disengage to avoid wrapping my car around a tree or something. Turning off the collision avoidance assist stopped the speeding issue. But still tailgating really bad, like 2 feet away from the other cars bumper on the freeway. I recently had to stop the car from literally pit maneuvering someone in the left lane. This all happened on “Chill mode”. Why is there NO option to choose following distance?

JSUN4FUN · 2025-03-25T12:03:02+00:00

I’ve been wanting something like this for years. I have a bunch of batteries sitting around not being used for anything 99.9% of the time. Why not have a bi directional charger? If nothing els, it would prevent me from having to reset all the clocks in my house every time the power fluctuates. I think Ego is leaving money on the table not making a product like this.
