X3 exploding window

Asked by Lisa Woodall

I purchased a 2010 X3 privately in October last year from an owner who was meticulous. It was a one owner, with low km, a BMW service and RWC. In February whilst parked in my carport the rear passenger door window "spontaneously exploded". I photographed the damage, having never seen anything like it before and contacted the BMW dealer to book it in for repairs. I then began to search the Internet for possible causes of this and to see whether this is a common occurrence. I also contacted an automotive glass engineer who explained to me that this was most probably caused by nickel sulphide inclusions created in the tempered glass manufacturing process and the age of my vehicle corresponded with the time it would explode if present. 

I explained all this, provided photos and requested that BMW pay for the replacement as this was a fault in the build of the vehicle and not due to any other causes i.e. driver or environmental. On the Tuesday I took the car in for inspection the door panel was removed, most of the glass shards removed and the regulator and cables inspected. I was told the mechanics of the car were in fine working order and the window ordered. I was told there was still no reply from BMW. On the Thursday I took the car back to have the window replaced. I couldn't hold off as the car was not secure to drive and park in its current state. Again, I was told there was no answer yet and they took the car to service. When I went to collect the car in the afternoon I was told they had not yet heard and I had to pay $850 for the repair and submit an email for reimbursement. 

I was not happy, felt I had been treated like a fool, but had to pay to get my car. Still, I submitted my claim, again detailing all the information, photos and confirmation from the expert and, unsurprisingly, was knocked back for refund. One week later I am in the back seat of my car and wind the window down (first time) and back up when there was a "clunk" sound and the window wouldn't wind. I rang BMW the next morning, took the car in the day after that and was advised that the cable had snapped and needed replacing and should look at replacing the regulator too, cost to me $960! I told the service advisor that this could only be as a result of incorrect fitting of the window I should not have had to pay for and am speechless that they would deny any wrongdoing. I have received an email today offering me 10 percent discount on parts and labour. I have never dealt with BMW before and am in tears at the appalling manner with which I am being treated now. Can you help me please?

If you haven’t had any direct contact with BMW to this point you now should make contact with the company’s head office and talk directly to the customer assistance people. Unfortunately you assume that it was inclusions in the glass that caused the window to “self explode”, but there’s no hard evidence to say that is what caused it. Same with the cable, which you believe was caused by something done by the mechanics when they worked on your car. Again it’s not possible to saw for sure that it was the mechanic’s work that did it. You need to clear your head and sit down with the dealer in the first instance and also BMW to seek a resolution for your troubles. The offer of 10 percent of the cost of parts and labour is a pretty miserable one; I would go for at least 50 percent.
