Plastic Underneath Cracking

JT Rock said:

I just noticed that underneath my XC40 Recharge, the plastic has some stress induced cracks forming on both left and right side toward the front. I don't know if it was from a service person or a another cause. Also, one of the screws wasn't fully tightened. There is about a 1 or 2 mm gap to the washer.

Anyone else have an issue like this?

I went and looked at mine this morning - but didn't see any damage or loose screws.

Update: I stopped at the service center and they put it on the lift for us to investigate. It was easy to see that the cracks must have been caused by someone who misaligned the lift arms. Very easy error to do because ICE Volvo's have the lift points in a different spot. They're ordering me a new liner.

So do they think this was done during assembly or something?

We didn't know. I wonder if it happened while held at port.

Any chance you hit some debris on the road? I had a similar mess on a past car.

Could be, but the plastic seems indented around the same four points near the lift points on all the corners of the car… is the liner functional? Any downside to not fixing it?

Maybe someone put it on a lift using the wrong lift points or adapter(?)?

I don't exactly know what all these panels are for, but I'm sure it's some combination of protecting the mechanicals under the hood and reducing drag. Personally, I'd talk to your dealer, if it's clearly some error on the part of someone putting it on the lift, they should be liable.

Edit - I may have misinterpreted the location of your photos.

From what I can tell, your marks are in front of the wheel. I found this bit in the owners manual, which is more like what I've seen before on other cars - between the wheels - so perhaps someone messed up lifting your car.

Did these issues ever get solved? Did the plastic liner get replaced and what was the cause?

As I recall, there were reports of this happening earlier this yea, so I made sure to check the underside of my P8 when I took delivery in early July. (I had none).

Yes, check for cracks underneath your vehicle after any service performed if you know it was on a lift. Mine was cracked because the attendant was a bit sloppy and missed the lift points by a few inches. It's all good after they ordered and replaced the parts.

I see. Is this a different lift point setup than the ICE XC40 due to the battery frame or something?

Is there a reason cars have plastic underneath vs something stronger and more able to survive impacts. I assume weight is an issue but considering how many bouncing rocks happen …

Anyone know how thick/strong the batteries bottom sheet is?

Weight, expense, ease of replacement... I can't think of a better material option. I think of it as a semi-disposable layer.
