Yes, I was a little surprised at the response! Basically they said “company policy” or some such thing. Not even an apology.
Even though it was a new car when I bought it, it was their older design (240). I imagine the CPU was sort of retrofitted to help meet newer emission standards. Perhaps design compromises had to be made. The car was otherwise well built; we had it nearly 15 years. But after that episode I vowed to never buy another!
