I worked in the brake industry for the first 15 years of my career and was involved in a number of campaign changes.
I recall one where the senior management were under pressure to provide an instant solution and didn't allow time for appropriate testing or validation. The campaign change was carried out 3 times before it was properly fixed as a result of which it dragged on for more than a year. Be careful about wanting quick fixes - brake system changes need to be properly validated and if it was me I would want a permanent fix and not a quick fix.
I am sure that they are working flat out on this and will want to get to a permanent conclusion.
