Loud compressor after 22 update

[sevengroove]

I know this is happening to a lot of folks after updating to 22, but just want to make it known that this is not exclusively a 22 problem. I am on 18 and have had this issue on my R1S for the past 2-3 weeks.

I wouldn't mind the noise so much, if the vibration in the pedal wasn't present. Feeling vibration through the pedal is annoying.

I haven't updated my R1S yet since its at service center for other items. Sounds like I should skip this new update?

I did the .22 update last night. Prior to the update, I had low compressor noise which was completely masked by the air flow noise coming out of the vents. The ambient temperatures have been in the mid to high 70s here. I tried it just now, post update, with 77 degrees ambient temp (my home weather station indicated temperature) and the noise *might* be slightly louder but it's hard to tell.

I did notice something interesting, I don't know if this happened before .22 or not. I had the door open and I put my foot on the brake. The compressor ramped up in speed, easy to hear since the door was open. I took my foot off the brake and it ramped down. Huh, how 'bout that? Anticipation of driving away? Depending on the speed of the compressor, I could feel what I would call a very slight vibration only at certain speeds, like there are resonant points. At some speeds no vibration noticed.

I will also mention behavior that I would expect to be completely normal. If you lower the temperature or increase the fan speed, the compressor ramps up as it needs to provide more BTUs of cooling to satisfy the demand.

I still have not had 95-100 degree temperature to see what happens, but from the sound of the compressor, I think it is running near it's top speed. It's not annoying to me and it is easily masked by the blower and radio. Standing outside the R1S, the compressor is no louder to me than the noise level of an idling ICE vehicle. So at this point I have no complaints......

Yep, same problem. Started with 2023.22.0. Contacting Rivian support is useless other than another data point of the problem. Their only response: make a service appointment, which is a 4 month wait. Which won’t solve the problem anyway. It needs a software update to fix the new “normal” to go back to the old normal. It wasn’t broken.

It is the most annoying “fix” I’ve seen in 10 months of updates. The internal testing bar is low before a release is sent. We are the beta testers. The problem is there’s no going back once you install.

This did NOT start with 2023.22.0. I just updated yesterday, but have had the same compressor problems on 3-4 days that it was hot here in Denver on the previous software version. It's happening now because it's finally summer, it's hot in parts of the country, and the compressor is working overtime to cool things down. I'm hoping it can be fixed with a software update and isn't a major issue because it sure is annoying when it happens.

I think there are two camps:

1. Compressor noise present prior to release in hot weather locations. Post release, some changes in ramp/velocity but noise persists.

2. Compressor noise not present prior to release (maybe only in mild weather locales?). Post release, compress noise appears.

Confirmed cases for both.

My experience is that it started when I updated to 22. My garage isn’t that hot and it makes the sound as soon as I get in, in the garage, where it isn’t hot.

Same. Super annoying.

Just got my truck back today with .22 on it. It's been cool today so I'll hold off on saying anything about how quiet my AC is.

I think this is both a hardware and software issue. The hardware is noisy for many folks when it really gets going. The recent update seems to increase the occurrence of the compressor running at full tilt, which just highlights the hardware issue.

I do also think this is a more obvious issue because the car is otherwise very quiet. My Tahoe gets loud when the air is at full tilt, but the engine is so loud you just don't notice it as much.

FWIW, and I haven't seen this mentioned here recently: I had noticed the extra loud compressor last summer, but update 2022.31.05 actually made it a lot better. The recent 2023.22 update has perhaps reversed some of that that, in exchange for more cooling, faster. So I do think software plays a factor.

It’s happening to me too. Immediately after the update. Super loud, vibrating floor pedal as well. My Efficiency has also plummeted. Was averaging well above 2.0 now down to 1.5 especially when the car first turns on for the first 10-15 min.

The count went from 26 this morning to 40. Just let the new update roll out and temps grind up to 100 degrees. The count will double or triple.

Same, under 72 degrees in my garage at 7:30am. Climate set to 69 on Auto. Walk out and suddenly reverberating around my garage is a captive weed eater giving it hell.

Really REALLY appreciate @Zoidz letting us all know that he is right and we are all imagining things. Thanks! Helps bunches!

I've had the issue since owning the vehicle but today, I remote started the AC and when I walked up to the car I could hear the usual loud buzzing but along with what was a very strong burning smell. Narrowed down the origin of the scent to where the wipers are which is also above where the compressor is.

Anyone else notice a smell that accompanies the buzzing? Something sure to burn out eventually.

My R1T started doing this post update also. Thankfully only lasts a few minutes. Not too warm yet here in SoCal so we’ll see.
