When I start the Max in the morning or whenever, there’s an intermittent buzzing/pulsing from the driver side engine compartment. I can faintly feel it through the steering wheel. It last several minutes until the engine warms up and seems to go away. Anyone experience this? I hope this isn’t a sign of things to come. Any help would be much appreciated.

 

do you have ABS? can you feel the brake pedal pulsating while it is doing this? i'm not talking about right as you start it up, because the pedal is going to pulsate due to the ABS system doing a self check. i'm probably way off but it was worth a try.

 

i get the buzzing but i think its something to do with the cat.......havent had it bother me enough to ck it out

 

yea i have that problem right when i start the car until it gets warm like you said but it also is taking me like 4 times to start the car when it is cold and no one can figure out what it is and i've sent it to the dealership and put it on a comp and still can't figure out wuts up. do you have the same problem.

 

does neone have this issue

 

If it is buzzing, it sounds like either a bad relay or a relay about to go bad. Check the Chilton or Haynes and there is a wire in the ignition harness called the cold crank wire, trace to see if it goes to a relay. If this wire does not get potential it is hard or the car to start when it is cold out.
