2015 with leaking rear shock @40,000 miles

Well add my car to the list of SS with leaking rear shock(s). Took it in for a 40,000 mile oil change (@40,135) last Saturday, and the multi-point inspection report came back with a leaking passenger side rear shock. Recommendation is for replacement of both rear shocks, for $1,620 plus tax.

Original everything as far as power train and suspension, and pretty gently driven. I do keep the shock setting at "Perf" most of the time though.

Put a call in to Chevrolet Customer Care today to request goodwill warranty repair and got a case number established. Someone will be calling me back tomorrow, hopefully with some good news.

If no goodwill, I will do the repair myself obviously and I won’t lose a lot of sleep over it. Things do go bad. But, it is still a bit disappointing that the oil seal has failed at such a low mileage – which I stated to the Chevrolet CC rep.

So we’ll see how it goes!

And, in the meantime, if someone could share the part numbers for the rear mag shocks I would appreciate it. All the online part sellers seem to only have listings for the standard version shock @ about $75 per. Somehow I think the adjustable dampening ones are a bit more expensive!

These are the rear ones with magnetic ride. 350 or so is best Iíve found for new ones. I have a leaky rear as well. But Iím on 80k miles and the leak is terrible not just a small leak itís completely blown out. Good luck with gm. Let us know how it goes

Thanks! For some reason all I could find were the standard version shocks, I tried 2015 and 2016MY's. Found them on rockauto for $399 (but AC Delco p/n), so ~$350 is better if it comes to me doing it myself.

The difficult thing about changing the shocks is that they have a wire pair that comes out a few inches. The wires are terminated in electrical terminals. These terminals have to be released from the actual electrical connector on your old shocks with a "depinning" tool so as not to damage the connector and allow the new terminals to slide in said connector and "lock-in". Kinda sucks but, some of the folks here have figured out how to do it.

Conventional wisdom dictates that shocks are replaced in pairs. I'm not sure that applies to magneride shocks as they don't wear like conventional ones and thus a new one and an old one should (in theory) perform identically.

I have no idea what the official line on this is though. (Or even if the above is true in practice)

I have the extended warranty with mine so if I think mine a leaking, back to the dealer she will go. Like Sheff mentioned, I am curious if they are replaced as a set (in pairs) or if you just swap out the bad one and keep it moving. If anyone knows, please post up.

The first one I de-pinned took 30 minutes with multiple sentence-enhancing adjectives. The second took 5 seconds. It is easy once you figure it out!

This is the newest warranty statement:

https://gm-techlink.com/?p=10379

Conventional wisdom for conventional shocks was to replace in pairs, or better yet all four when mileage/leaking/testing denotes it's time. On low mileage units I subscribe to the newest policy; but with a singular failure close to B to B mileage expiration I do not and would 'figure out a way' to do an axle pair.

Magride performance does not degrade as conventional shocks do. Yes there can be electrical and or seal failures; so for them I subscribe to the newest policy.

Interesting article. This jibes with what the service adviser told me, that GM will not warranty unless the shock is really leaking bad, and that suspension is "bouncy". Can you imagine a Z06 bouncing twice before settling in, ever? Maybe a big SUV. That is a very unscientific way to determine loss of dampening. Looks like GM is really trying to reduce warranty, at the expense of the customer.

In my case, the recommendation by the dealer was for both shocks to be replaced. I'm of the same mind as CB here, since it the shocks are magnetic controlled it would seem like if the shock was functioning then mixing a new with an old should be fine. I might change my mind when it comes to it, though, assuming that GM denies my request for goodwill warranty.
