I’m just relieved. Because I intend to keep the car until next spring, I did not want the worry of cost incurred to replace them. If as it appears, I have the latest design (no idea how), I don’t have that concern.

Indeed. Whatever the reason for replacement early on it's good to have the later design.

The flaw in these strut designs is that water gets into the bottom spring section when the tailgate is closed. Blue arrows in photo.

This causes corrosion of the springs and eventual failure.

When the tailgate is opened, orange rust water dribbles out of the strut onto the car body and rear lights. Red arrows in photo.

After giving it some thought, i came up with a 'hack' to cover the joint when the tailgate is closed to prevent water from getting in. It's not pretty, but it does the job quite well. see 2nd photo.

I looped a red tie wrap around the strut and closed the tailgate. This pushes the tie-wrap up to the position where water ingress occurs. I then took some electrical tape and folded 1/3 of it back over itself so that you get a non-sticky section to go around the tie wrap. Wrap it around the tie-wrap as shown in picture below.

Now when the tailgate closes, the joint is covered and water should now flow over it instead of into the strut and cause damage to the springs.

If anyone can think of a more elegant solution - please share. :)

So you're having problems with the updated design?

It appears so. The water seal (if there is indeed one) between the 2 sliding parts doesn't seem to function. Water gets in after a shower. The right strut makes clanking noises when it opens.

So what i've done is really an attempt at preventative maintenance. I've added a video to show how it all comes together.

Love the tape idea. I may try self amalgamating tape to form an actual seal at point of closed. It can also be built up in layers quite easily and remains flexible. When I've done it will post here

K9plus1 what MY is your car, don’t appear to have an issue with the revised struts fitted to my car, even after the torrential rain of recent.

What's a MY? Year of manufacture? 2020.

I'm sure the fault doeant apply to all. Perhaps the seal on this strut has failed.

I have self amalgamating tape too. What a great idea!

If a 2020 model suspect it still has original struts ( unless replaced with updated design)which were subject to water ingress and erosion. Did you get a warranty when you bought the cat, if so and still within the warranty period, take it back and get sorted.
