Possible position sensor out of whack. Or struts wont release air. Did you check for any rss or tcs codes.acoloreo said:Hello all! I am a new 98 Seville SLS owner. Just got it 2 days ago. It only has 42000 miles, but the rear suspension feels very high, and bouncy. When I hit a bump, it feels like the front hits hard, and the back bounces a little. The car does not feel balanced. When I drive over a speed bump, the rear bounces about 3 times. Yet, when I got out of the car, and pushed on the trunk, the rear suspension felt stiff. Am I crazy?
