So I am definitely not a car guy. My wife drives our 2004 Jeep Grand Cherokee special edition, 150K miles or so. Recently, it has begun to shake or vibrate after it’s started. The shaking goes away after you drive it a block or two and it doesn’t happen every time. At the moment, there’s no check engine light on. My wife is 7 months pregnant and has always been a bit more high strung about her cars, and every noise, groan, clunk or rattle she gets concerned about if the car is safe to drive.
Anyone have any ideas what may be wrong, if it’s safe, and whether or not it’s a big expensive fix or if I just need to bite the bullet and start looking at a new vehicle?
