Roof Delamination Still Haunts Some Cadillac XLR Owners

On June 3rd, a 2005 Cadillac XLR owner was driving down a back road in First Coast, Florida, when suddenly, the roof panel flew off her XLR.

Francesca Giannini, the XLR’s owner, bought her 2005 Cadillac XLR new and never showed any structural issues during routine maintenance checks.

A witness who was driving behind Giannini, said the roof panel went airborne and narrowly missed other cars, flying off to the right and coming to rest flat on the grass.

Witnesses in one of the cars behind Giannini said the airborne roof narrowly missed other cars.

This isn’t the first time we’ve heard of this issue with the Cadillac XLR.

One of our forum members, nicholas.brady had the same thing happen to his 2005 Cadillac XLR.   He writes:

“I’m posting this because after a long search online, I found nobody who had this issue, despite the Cadillac dealer telling me that this is a “common” problem.

This is my 05 XLR, it started to get some wind noise and I figured a seal had started to wear. Dealer looked at it and said the same and recommended a silicon product for the roof seal.

Then while driving down the highway at around 70mph, the roof panel flew off the car. Thankfully it didn’t hit anyone or cause an accident.

So, make sure you get your wind noise checked. Apparently this was an issue with Corvettes around that time, but I’ve seen nothing on the XLR. “

The 2005 – 2007 Corvette had a similar issue with roof delamination and as a result, GM issued a recall notice for those models as outlined below:

Since the 2005 – 2009 Cadillac XLR was built off of the C6 Corvette chassis and on a separate line at the same assembly plant as the Corvette, it’s quite possible that the same adhesive used to bond the roof panels together on the C6 Corvette was also used on the Cadillac XLR.

Are any other Cadillac XLR owners having this issue?
