“My car stopped working all of a sudden in the middle of the road. no warning signs were made nor any of my lights came on. it’s rough running and never stays on long to drive. when i brake it completely shuts off. it overheats without the temperature gauge telling me it is. i don’t know exactly what is wrong but it’s not working now. i couldn’t go over 35 mph without it shutting off either.”
“WITH MY ENGINE I HAVE TAKEN MY CAR IN FOR AN OIL CHANGE ON TIME SINCE I'VE GOT THE CAR. THAN RIGHT BEFORE ONE OIL CHANGE I HEAR A KNOCK IN THE ENGINE. SO I GET AN OIL CHANGE AGAIN AND IT WAS STILL MAKING THIS NOISE. FOLLOWING THAT MY AIR CIRCULATION FOR THE FAN WOULD STOP WORKING AT TIMES. MY RADIO ELECTRIC LINE SEEMS DAMAGED. WORKS SOMETIMES.”
