If your company is willing to continue putting up with the level of quality received from this supplier, then simply close out the CAR with a statement to the effect that this supplier's current quality level is acceptable as is, and drop the issue (do not continue sending more CAR's to the supplier and shooting yourself in the foot).
But, if their quality level is not acceptable (it impacts your ability to meet schedule or your quality requirements) then by all means let your supplier know (the suggestions of others here are quite good).
I for one am a proponent of speaking directly to the head honcho and letting them know of my companies displeasure (and the possibility of seeking out another supplier - whether you really are or not).
Am I gettin mellow in my senior years? Probably.
I experienced this scenario [unanswered CAR] dozens of times over the years.
As I grew more experienced and got grayer, I realized the issue had two sides.
The primary reason a supplier ignores a CAR is because the customer did not work out the scenario as part of the contract in the first place. This is particularly true where a customer orders a proprietary item from a single source supplier. If the product is not custom made to the customer's design, asking for a CAR (as opposed to mere replacement for faulty merchandise) is unreasonable.
The other side of the coin is that the supplier may be absolutely incapable of addressing
ANY CAR because the internal QMS doesn't have a mechanism for this. This is particularly true of model and prototype shops used to "tinkering" with products and processes and unwilling to waste time completing paperwork for a small production run (include machining job shops in this category.)
The customer may be so hidebound in filling in blanks on its check sheets, it doesn't stop to determine whther the CAR is one aimed at a systemic problem or a one-time glitch. One late delivery may not be reasonable cause for a CAR.
Too frequently, issuers of CARs don't have a true picture of the real purpose of a CAR. It is not a replacement for normal communication between customer and supplier. Suppliers are remiss and trigger CARs when they know they will be late on delivery, but do not proactively alert the customer. Customers are remiss when they trigger a CAR without a phone call or email asking for an explanation of the perceived nonconformance.
Customers often issue CARs to suppliers that are actually in error. I have seen instances of customers issuing CARs because of a perceived product nonconformance only to later discover their incoming inspection was flawed and the product was actually perfect.
Bottom line:
Try a little tenderness. Problems between customers and suppliers are not resolved at incoming inspection level - they need to be escalated to the "suits" who get paid to
resolve issues, not to
detect them. Before escalating the problem, try a phone call to see what the real issue is.
