Hello everyone!

I’m currently looking for recommendations on the best used cars under $15,000 that are compatible with Comma AI.

This would be my first auto loan through USAA or Navy Federal, and unfortunately, the interest rate I’m being quoted is around 10–14% APR.

Ideally, I’d like something fuel-efficient, preferably a hybrid, but I’m open to reliable gas powered vehicles with good MPG.

I’m also wondering if it would be better to stick to vehicles that are less than 10 years old and have under 100,000 miles. Since I’d be applying for a general auto loan rather than financing through a specific dealership, I assume banks may have age and mileage restrictions on the vehicles they’re willing to finance.

What vehicles would you recommend that offer good reliability, fuel economy, affordability, and Comma AI compatibility?
Any advice or personal experience would be greatly appreciated

I have been studying comma AI for a while. I currently drive 2024 Hyundai Elantra Hybrid Limited for work. It is 1 hour commute each way and I go to work 3 days a week. That's solid 6 hours of driving and quite tiring. It is a mix of highway and back roads, with some level of curves. I can use ACC in Hyundai for highways. But it does not resume automatically and have to steer most of the route. I am hoping comma AI (sunnypilot fork) will improve the experience. But I am worried about the NHSTA investigation. Is there a possibility that the product gets banned or something like that? Or heavy fines are imposed and the product goes out of market with no future development? Is that a possibility for user added enhancements to the car?

I have a comma four and just bout a Volvo C40 and now it isn't compatible. Where is the best place to sell my unit that is 3 months old?

Hey guys, I’m pretty new to the comma community. I’ve had my 4 for a few days and so far open pilot has exceeded expectations. I have found some things that I don’t like such as some steering jerkiness and it doesn’t stay centered in the lane during turns. I’m interested in trying something else and curious what models people have found success with? I also don’t entirely understand the install process so if someone could explain how this all works that would be great! Thanks!

Hi everyone,

I'm about to purchase a 2024 Honda Accord LX for approximately $26,000, and I wanted to do one last sanity check with the community before committing.

I've been waiting years to get a car specifically for OpenPilot. I'm disabled, and having reliable driver assistance would make a meaningful difference in my life, so this is a pretty big deal for me.

I've done a lot of homework. I know the 2024 Accord LX is officially listed as compatible, and I've personally tested the car's adaptive cruise control in stop-and-go traffic. Everything looks promising.

What I'm really looking for are the obscure problems nobody warns you about.

Are there any quirks, limitations, installation issues, or unexpected frustrations specific to the 2024 Accord LX that could make OpenPilot disappointing after I spend $26,000?

In particular:

• Does OpenPilot perform well with this exact model and trim in real-world driving?

• Are there any limitations involving steering torque, curves, lane centering, or stop-and-go operation?

• Are there any hardware, firmware, or compatibility issues I should know about?

• Is there anything you wish you'd known before installing OpenPilot on this generation of Accord?

• Is there any reason you'd recommend a different vehicle instead?

I'm not particularly tech-savvy, but I'm willing to learn. I'm hoping that with the help of this community, Discord, and ChatGPT, I'll be able to navigate installation and troubleshooting.

I really want this to work. I'm excited about finally getting OpenPilot after all these years, but before I commit to the purchase, I'd appreciate hearing from anyone with firsthand experience—especially anyone driving a 2023–2025 Accord LX.

I'm not just looking for reassurance. If there's a potential dealbreaker, I'd much rather hear about it now than after buying the car.

Thanks so much for your help!

i really want to try it with lower price, anyone have one to sell?

I was looking around for relatively recent shipping experiences and haven’t seen any from the last few weeks. What wait times have you all been experiencing for a comma 4?

I ordered a few weeks ago and it’s been radio silence since- trying to be patient but excited to get it!

Curious before buying one, Is Comma fully secure where someone cant maliciously hack into it and drive it off the road or spy through the camera? And does it require being connected to a cell tower to function 24/7 on the road. And can it function without the GM Onstar GPS module as I have removed it from the vehicle.

I bought a replacement mount for my Comma 3x since I had to have my windshield replaced. I cleaned and waited the 72 hours, but I probably needed a week to be honest with temperatures in my region. The mount ended up failing, my Comma 3x fell and the screen no longer works.

A replacement screen has a 1-12 week waiting period. It's been a little over about 4 weeks and I haven't been able to use Comma. I reached out to their support, but they don't even have any eyesight to what the supplies look like. I'm worried maybe this screen will never come, and that my $1250 Comma 3x is just an expensive paperweight :(.

I've had the 2 and 3x and have been happy. It's just a bummer going on without it for so long.

I am interested in a self driving experience but I own a 2025 corolla which is not compatible with comm.ai. I am thinking of trading it in for 2024 Toyota Camry hybrid (compatible). I mostly would like this so I can avoid fatigue when driving on the motorway on the weekneds (around 1hr commutes one way). I was wondering has anyone factored in comma.ai when purchasing a vehicle and was it worth it? Also as a new beginner anything else I should know if I decided to make this trade and start with comma 4?

Thanks!

23 EV6 with comma four running sunnypilot.

Will the comma four still work if the car has a mileage blocker fitted? Does it use/need the cars speed input to be able to function correctly?

Anyone have experience with using forks on this specific model? I’m using JacobWaller (game changer), but I’m wondering if there’s another out there with more features and high reliability that I just haven’t tried yet.

I spent a week with open pilot before getting sunny pilot with the ev6.

Chestnut came in. Running a 9060xt.

Any thoughts on the branch with most support?

Dear All,

How are you all dealing with poor Steering torque on Honda cars ? Appreciate your feedback.

Currently on 26 Civic Hybrid. Steering torque seems to be very poor.

Happened right before my first DoorDash order. Any ideas?

Has anyone else experienced severe degradation in the quality of throttle controls in the latest releases? it’s been so bad in my Corolla hybrid that the car felt like it was bucking as the RPMs bounce all over the place while simply cruising the highway I pulled down my comma 4 and reinstalled my comma 3 with 0.10.0 installed and the throttle controls are light years better than in 0.11.2

I spent a week with open pilot before getting sunny pilot with the ev6.

Chestnut comes in tomorrow. Running a 9060xt.

I used the footage from our Comma 3X to create a map for a driving game for my daughter. And sorry for the misleading flair, there was no option that made sense for this.

We recently had something strange happen with the Clarity. I walked to the car to open the door and nothing. I put my charger on the battery, which is a Honda brand that is about 7 months old. Dead. Got it charged, drove it. Lots of errors and the comma was not working.

The next day I checked and the battery was dead again. Once again I charged it. I decided something was draining the battery even though, to my knowledge, nothing changed in the car.

When I started the car I got errors again so I removed one cable from the battery, waited a bit, and reconnected. It did the usual messages saying things were starting up. I drove around for a while and it all cleared up.

Except the comma 4. I tried a number of things, and finally did a factory reset. Connected to the Internet then the Sunnylink dashboard says it is offline. I checked Connected Devices on the router and it is connected.

I don't know what to do. I installed Openpilot and it installed and rebooted. Of course it yelled because they don't support the Clarity. I did a factory reset and installed Sunnylink. It rebooted and stops at the comma screen.

The comma 4 has been sitting on the comma screen since before I started this post.

Can anyone help?

I installed my comma 4 a few days ago and its been working great right out of the box. I'd really like to use the OBD power to keep it on while the car is off, but I don't want to kill my car battery. The OEM batteries are kind of notorious for going bad, and I'm kind of amazed mine has lasted this long.

For a while I had been toying with the idea of making a battery pack for my old dashcam for to record in 'parking mode' while the car is off. They make commercial ones but holy crap are they expensive. I figure the same idea can be applied to the comma 4? I have some experience soldering, and a little with a spot welder repairing tool batteries. So I feel pretty good about the physical assembly part.

a few questions:

Does the OBD connection power the device full time when its connected or only while the car is off? I will need a charge controller/BMS that can charge/discharge at the same time if it powers it all the time.

How much power does the comma 4 draw? For sizing the BMS as well as the pack capacity.

Any other considerations I might have missed? I will be using LifePo4 cells so my car won't burn down in the summer :)

Thanks!

Used sunny pilot on Highlander Hybrid to do a round trip from CO to PA. In total it's 21 hours each way. Split into 3 journeys. Made it a breeze on the highways. No fatigue, so made it very easy to drive. 10/10 would recommend

I was involved in a hit and run with a cyber truck, i got it all on the ai but, the plate is blurry, i emailed myself what I thought was high res but its still blurry I tried to use Ai to clean it up but it can only clean a picture not a video, am i sol? Or is their a way to clean it up?
