Hello out there I appreciate any advice. Recently my 550 was working perfectly and suddenly the dashboard lights flicker on and off. ABS, ESR, Air Bag, Brake,Fluid level, and the intensity of the dashboard lights diminish. This is usually a couple minutes after starting the car. All of a sudden, the car almost wants to stall and it immediately goes Back to normal. I took it to my mechanic,And he ran all the tests. He said all is functioning well, charging well, etc. As usual, will you take it to the mechanic it performs well. Is this a fuse box issue, or a voltage regulator issue. Or possibly a faulty battery? Appreciate your comments.
