A recall procedure by any manufacturer is a herculean task that holds high responsibility and authority to the QA/QC department.
Every material used in manufacturing (Raw and finished) is kept as samples ('n' number) in batches from 'every' vendor for a specific time of 2-5 years. These samples are given a specific code along with the data from every vendor is compiled and store in their database for future requirement 'IF' an issue arises - This whole thing is called 'Traceability'.
Now the letter as it says is for cars manufactured between 2009 to 2011 are a part of the recall for the RHS drive shaft replacement where the affected part is narrowed down and the vendor who manufactured it is informed regarding the problem being faced by customers. Now how does the company know which batch is the faulty one?! They keep track of customer complaints and do a trend analysis for the complaints to see how frequently the issue recurring. The high the delta value the specific part is narrowed down.
In this case it was the drive shaft IMO. Now the QA/QC department get the samples for that specific batches of drive shafts and does the required testing in their labs for faults. Once the fault is diagnosed and confirmed the recall procedure is initiated.
The faulty drive shafts that were found have a specific code (Batch number) which is kept in the database as to which cars (read VIN) had these faulty drive shafts used on them during the car manufacture. Those specific VIN's are traced out and the customer to whom that car was sold is contacted for the replacement under the recall program.
In some programs the batch number given to the faulty part is large in number so the year of manufacture of the faulty part zero'ed down to the nearest affected car is put in the recall program hence the month is also bought into picture.
Many people here feel it is a insult and a negative opinion on the manufacturer but IMO it is great job to initiate this and successfully get the cars recalled along with the parts changed FOC. It is a loss for the manufacturer in terms of part cost, labour, man-day spent for the repair job (An occupied bay).
Hope this clears your doubt on the Recall programs by manufacturer. Quote:
