Thanks. Yes, I did a forum search too and did not find anyone complaining of shock issues with a low milage CX5.a quick forum search doesn't reveal any previous large discussion around premature shock failure. While in your case it is a bit low mileage, parts fail and that is why replacement parts are available. Things like road conditions, region where the vehicle is used, and just plain old luck are factors as why it failed.
Since your warranty "just expired this past summer" and your mileage is low, a call to Mazda North America to plead your case for coverage could prove to be fruitful. Remember be kind and humble and be amazed how far a good attitude gets you.
for reference this thread was for an earlier model:
2013~2016 - Broken Driver (Rear) Strut/Shock Absorber
Hi All, It's that time a year again when something breaks in my car (approximately 86k miles) and I need to replace it. When I was driving, I noticed a clunking/thumping noise when rolling over bumps/uneven pavement. At first, I thought it was something in my trunk causing this noise but after...mazdas247.com

DIY rear shock replacement
Has anybody done a rear shock replacement on a 2016+ CX5 themselves. I was hoping it was going to be as easy as other cars I've done but it really looks like I need to remove the rear coil spring before I can get to the bottom nut holding the shock on. How did you do it?mazdas247.com

2017~2024 - CX-5 Aftermarket shock replacement suggestions
Hello fellow cx5 owners. I’m about to put on some corksport springs and replace my shocks while I’m at it. But I can’t seem to find much feedback on replacement shocks. I would like to stay close to stock comfort ride as much as possible and don’t want any stiffness. So far it just looks...mazdas247.com
Hey that's a great find! I was searching for something like this and could not find it!Yes this seems to be a know issue on the 2017-2020 CX-5 models, may be due to a lack of sealing performance. According to this TSB, the production process of the shock absorber was modified.
I was surprised you couldn’t find any complaints on early failing rear shocks in the forum by the search. I’ve seen many such complaints in past years since gen-1 CX-5, and Mazda has issued several TSBs for gen-1 and gen-2 CX-5’s such as those posted by Hawke. Just see how many revisions on OEM rear shocks and Mazda seems to keep changing different versions of rear shocks may be to fix the leak problem?PS, being proactive I just filed a complaint with the NHTSA. Since these shocks are known to be defective and loss of function of shocks could negatively affect the CX5s handling, it's a safety issue, and there should be a recall. Just my opinion!
Seepage or leakage, the shock absorber itself may not lose its functionality when the oil lost is in very small amount. But between the two rear shocks on OP’s 2018 CX-5, only one shows oil mark from seepage. This definitely means the one with oil mark has weaker seals developed hence let the thick shock absorber oil passed the rod. Keep in mind the oil amount is small in shock absorber, hence even tiny amount of seepage could shorten the shock life significantly.Weeping to me is the shock shows some oily residue but, no drips. or buildup. This would not qualify as a BLOWN shock so this pure nonsense. Ed
