It is unlikely that it is worthwhile taking action, unless the cost of the repair was unusually high for an 11-year-old (e.g. it is a classic car, a very high-end car, etc.).You say there was no injury. That means that the most you could recover is the cost of the repairs--or the value of the 11-year-old car, whichever is lower. That means you probaby cannot recover too much money. On the other hand, to recover from the manufacturer, you'd need to be able to prove that it was their part which overheated, and that the part overheated due to bad design or manufacturer--and not, say, because it suffered some damage during the 11 years since installation. To do this would require expert testimony and tests, which could easily cost more than you could recover.
