Rotten Egg Smell?

[EdwinDrn]

Perhaps this is a coincidence, but this is the second time I pull up and smell what appears to be 'rotten eggs'. I did a quick search and saw a few possibilities. Im wondering if anyone else has experienced this smell after driving for a bit.

I've got a 2019 Si, I am at around <1200 miles.

Did you do any bolt-on engine/exhaust mods?

It goes away as the miles accumulate.

No mods. 100% stock

I do hope so.

Hmm seeing how your car is so new, usually when you get a rotten egg smell, it’s coming from the battery. But in this case, must not be since your car is 2019

I got it when my car was new and low mileage. At 9 months/7500 miles I don't remember the last time I smelled the rotten egg smell. It's been several months and thousands of miles.

Same here. The smell was strong in the beginning but almost non existent now. I still get the smell after hard driving Evey now and then.

Basically don't worry about it.

Had this in my car, noticed around 15,000 miles but went away around 20,000. I believe there is another thread on this explaining why.

Bought my 2018 hatch approx 3 months ago, had 11K original miles and now sits at 13K. I have experienced the rotten egg smell twice, both episodes lasting a couple of hours. First time I had driven a couple of hours and increased altitude by 8k. Left the car for about 1.5 hours and returned to the foulest stink. It was very low on gas at the time.

Second time, I had driven a couple of hours and decreased altitude by 8k. Parked it in the garage for a couple of days and the stink returned approx 48 hours later. How can it stink when it hasn't been driven for 2 days?

I live in Hot as Hell Palm Springs where my west facing garage is typically 100+. The smell appearing after not being driven for a few days has me baffled

Battery ??? Not heard that one before.

It's much more likely to be because Honda Skimped on the Catalytic Converter to save cost.
