The mounting bolts for the front brake calipers may not be tight. If the bolt backs out, the brake caliper could separate or rotate away from the bracket and the brake will fail at that wheel. It could also damage the wheel and cause a flat tire. Either condition could result in a crash. Dealers will tighten the mounting bolts to ensure they are secured.
Please contact your Infiniti dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.

IF THIS OCCURS, IT WOULD ALLOW THE CALIPER TO ROTATE OR SEPARATE FROM ITS MOUNTING BRACKET. THIS COULD CAUSE THE BRAKE TO FAIL, REDUCING THE VEHICLE'S ABILITY TO STOP. IT COULD ALSO DAMAGE THE WHEEL, CAUSING THE TIRE TO GO FLAT. EITHER ONE OF THESE CONDITIONS COULD RESULT IN A CRASH.
