For all those who have posted claiming that the non-locking fuel door is ok, obliviously you are blessed with a distinct lack of enemies or crazy ex’s. I was shocked, if not completely horrified to discover that my ~$40,000 Cadillac did not come equipped with a feature that is standard on almost every other car I have owned in the last fifteen years (including such plebian fare as a Saturn SC2).
A long time ago, I had a friend who had to shell out the cash out of pocket to replace an engine after it had been sabotaged by an unkind person. Leaving so obvious a security hole in an otherwise nice package seems a gross oversight on the part of Cadillac.
Set aside revenge as a motive, there are plenty of malicious people in this world who are more than willing to deface, if not completely ruin, a vehicle because they are envious of other people’s success. I live in a condo complex and routinely the BMW’s are keyed. So far my precious CTS has been spared, but apparently someone has a real dislike for people who drive better cars than them. If they were to escalate to engine sabotage, sure insurance would cover it, or warranty, but who need the hassle? I would much rather the manufacturer address the issue before I have to replace my engine.
The CTS should have a locking fuel door, period. The lack thereof is a major oversight and short-change for those of us who do not have a locked garage in which to park their cars!
