AFTER I BOUGHT THIS CAR 1 YEAR AND A HALF AGO I HAD 2 ENGINE PROBLEMS FIXED ALREADY. NOW, I HAVE BEEN EXPERIMENTING 4 TIMES A TOTAL LACK OF HEADLIGHT AND PANEL LIGHTS WHILE I AM DRIVING. IT LASTS SECONDS, THE IDIOT LIGHTS COME BACK WHILE I AM DRIVING. I WAS VERY SCARED BECAUSE IN ONE OF THESE TIMES I WAS DRIVING AT NIGHT IN A BUSY HIGHWAY AND IT WAS RAINING HEAVILY, I COULD NOT SEE ANYTHING .I TOOK IT TO MCGUIRE TWICE FOR THIS PROBLEM AND THEY CAN NOT FIND ANYTHING WRONG.
