Is it possible that the sensors were broken or buggy ? A long time back, I had poured all of my money into buying a second hand Porsche .One day I was cruising merrily on I-90 when my car caught fire, even though all the indicators were normal. Turns out the indicator were not functioning -- the last mechanic (not a Porsche dealer )to tune the car had effed up the indicators. ( I have stuck to Hondas and only authorized dealerships for repairs since then). I may be doing wishful thinking here but Car Journalist are could be biased , snarky , they might embellish a bit but they are rarely outright liars.
