A little background before my actual question. For the past 4 months I have been driving around (about 8,000 miles) and have had zero issues with my car. This all changed yesterday. I woke up to drive to work as usual, but about halfway to work, my car started making this awful rumbling sound whenever I would coast or apply the breaks. At first I thought it was just some snow build up, but it got worse the more I drove. I made it to work (10 miles from my house) and got out of the car to check and see what was wrong (expecting to kick some snow off). To my dismay, I found 4 out of 5 lug nuts missing from my back driver side tire and 1 missing from the front driver side! I called the dealer who changed my oil (two weeks ago), etc. and they were just as shocked as me. They told me to have it towed to the nearest dealer and they would foot the bill (which they did). In total, 13 out of the 20 lug nuts were damaged or missing. Today I get a follow up call from them to make sure everything went ok and they informed me that when they did the oil change, they did not rotate the tires (by my request). So what we both thought was improperly torqued tires, may not be the actual cause of my almost disaster. Now I'm super paranoid that someone did this to my car on purpose, but I just can't explain it in my head. My car has been fine for months and then all of a sudden 5 lugs go missing and 8 are damaged? Plus, who would take the time to remove 4 lugs from one wheel and 1 from another??? I guess people will do anything. I've very upset about this because I live in a nicer area and now I'm never going to be able to not be paranoid about my wheels. Ugh. Anyway, on to my question. I'm looking into locking lug nuts for a little added security and peace of mind. I know they won't keep my lugs from falling off, but at least I'll be able to narrow down the cause if this were to happen again. I'm looking for a set where all 5 lugs lock with the same key. Does the even exist? All I've been able to find is 4 normal lugs and one that requires a key. Any help would be much appreciated. Thanks.
