Re: A few clarifications
"The intercooler-recuperator was designed and built by an American defence company."
If I buy a brand spanking new car and it fails/breaks down on a regular basis and has a provable design flaw, I expect the manufacturer to repair or replace at no cost to me and supply an equivalent working vehicle for me to use while they fix the problem. The fact the supplier bought in parts from outside contractors isn't my issue. Let the vehicle supplier deal with the their suppliers and claim back the costs from them.
