Engine smell for 2019 ram rebel

[RamCares]

i have the same issue. My truck is a 2019 limited approx built date is late 2018. i started to smell this weir smell but thought it was water intrusion or something inside the car. It has not gone away I had the car clean and deodorized but it is still there. I just took it to the dealer and they told me they couldnt find the issue.

Hi @MIAMIRAM - I just had a chance to respond to your PM on this!

While I don’t have this issue w/my ‘20 Rebel... yet, it was a problem with certain Gen 4 model years. Countless owners were complaining about the smell on other Ram forums. It was ultimately discovered that the smell was caused by a new OAT/HOAT (purple) Antifreeze and its chemical reaction to a sulfur-cured rubber compound in the coolant hoses. It was also reported that this antifreeze was reacting with a chemical used in prepping the engine block during production. I believe that there is either a TSB or STAR... I’m not saying that this is still an issue, but there’s a lot of information on it if you conduct a Google search...
