NHTSA defect investigations
Federal safety investigators have looked into 2 possible defects involving the 2015 Honda Civic SI:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
Electrical overstress
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events.
What 2015 Honda Civic SI owners say
Suspension
I have had my car for 6 months and I have had to get it aligned every month because the rear end will not stay aligned which is coasting a bunch of money I would like to get a investigation started on this because it has to be something wrong with this it has almost caused me to wreck 3 times
I have 58,000 miles on my car atm and I'm already having to replace shocks and struts because they are shot and I don't live on bad roads at all and I have to purchase 4 new tires because of this
Transmission & drivetrain
Noticing right now just the intermittent stage of this new clutch noise on an uphill/incline also the incredibly common vtc actuator cold start noise on basically all k24 variations, still researching if these two are correlated which I believe so at this moment I write this. I just bought this 15' Civic SI 9 months ago, 06 of 18' with just over 20K. Had the cold start noise probably 5 or 6 months in as it becomes winter and now I'm getting clutch noises plus I feel slight decrease in performance. From what I've read and I've done way too much research, it starts out as a typical noise even Honda Canada themselves claim as nothing but had lead to cases of catastrophic failure to complete head replacements to complete clutch replacements and some cases sounds returning due to defective OEM design. …
Clutch makes a metal grinding noise when releasing from a stop to start moving forward in 1st gear. This is a known issue with the clutch spring.
