rear suspension makes a "clunk" noise when going over bumps. 2 mechanics have been unable to fix and we have been driving with that noise for three years now. We even replaced shocks in the rear but noise stayed.
front suspension springs have rusted at the connection plate under hood and makes a 'boing' noise when you turn the wheel at slow speeds. Mechanic says it is not a safety issue and recommended putting up with noise (cost to fix was high).
Tranny on a rare occassion will slip/slam when putting into drive and getting into first gear. If you feel it not engaging, let off of gas for a second, t engages and then it is fine. rare, ut thought I would mention it. been like that for over a year and keeps on driving. Otherwise, ranny shifts smooth.
