Hello all. Recently acquired a '07 SL hatchback for a commuter. I drive about 85 miles a day commuting, nearly all interstate. I got the '07 from a family member for basically free to replace an old Jetta I used to commute with before. The versa had around 115k miles when I acquired it. So far I'm seriously not impressed. I've done a ton of repairs on this thing, both cosmetic and maintenance issues... Pathetic how the gas mileage is worse than my old Jetta. Maybe you guys can steer me how to improve it? I have the cvt trans. Maybe that's not conducive to good mpg? Really, motor wise, I've only just put in synthetic oil and a K&N air filter. When I first got this versa, it had a horrible shake when applying the brakes. Naturally, I ordered new pads and rotors. Then I noticed the subframe bushings were shot; replaced those. Also put on 4 new tires and had the wheels balanced. After replacing these, the car then developed a strong left pull in the steering. I took it in for an alignment. They showed me the printout and said its straight as an arrow, yet the left pull still remains. Also, at cruising speed, after driving about 15-20 miles, the car suddenly develops a shake, seemingly out of nowhere. Can't figure it out. Are these common problems with high mileage versas? Going to replace the worn out struts next, any recommendations?
