Problems with 2005 Honda Civic TIRES

On 2/26/10, i had 4 new tires installed in my 2005 civic; at 56,000 miles. even purchased the warranty. about two weeks later, i felt a very mild vibration between 48-52 mph. i didn't make such a big deal of it then. the past 6 weeks or so, about 60,000 miles, the civic's vibrating has gotten worse between 48-52mph. i took it for it's maintenance, had everything done, especially the break rotors and alignment. the vibrating has not stopped. i brought it back to the dealership. according to them, the car was checked, and felt the vibrating. car was re-aligned, the said it was the rear struts. i had them replaced with a different auto mechanic, then had it re-aligned once more to another auto mechanic. still vibrates. brought it back to the mechanic who installed the rear struts. he did a test drive, and balanced the tires. the vibrating is still there. now it's between 48-60mph at random. sometimes it does it, sometimes it's mild, sometimes it stronger, depending after my apply the brakes. the vibrating occurs under the seats, floor, rear, some is felt very mildly on the dashboard. could be since the rest of the car is vibrating. i'm very frustrated. *tr

At 1:30 pm pst on 17 february 2006, i was driving at approx. 70 mph on california state route 73 northbound, a freeway. the car was in drive and operating normally. i used the right turn signal to change lanes, but as i pushed the lever, another car already in the lane honked at me and i was upset. then suddenly, without the key moving, the car spontaneously shut itself completely off. the console went dark, and then engine first went from drive to neutral, and then ground to a halt, spontaneously. the key didn't move. *nm
