l have a used Suzuki Aerio S its having 100K miles on it, but whenever l put it in drive after reverse gear l can feel strong vibration, otherwise it runs well and reverse gear is excellent and if put it straight to drive it does not make that vibration, but only when l Reverse it put it in drive that l feel that strong sensation. Why so give me advise. How bad is my car and what potentially could be wrong or do some cars they do it

Could be nothing serious. First have u had the car up to see it first. Most driving vibrations r caused by many different things down there. You have to look at the operating system piece by piece. Try this, get ur drive shafts checked u can do this by lifting on it towards the top of the car. Look for movement in the joint & in the shaft itself. If there is play in the shaft then it could be the tranny mount. If there is play in the joint have it replaced 2 hours labour & parts. Reason for vibration.. When u put the car in either gear ur shaft moves to compensate for the direction. If the play is in the shaft it is moving out of balance. Second thing to check would be ur braking system check rotors & callipers.good luck.

Check the transmission! Take it to an honorable and reliable mechanic and get a diagnosis in person! (Make sure the transmission fluid(s) are topped up.)

Check your engine mounts. front back and side

Ditto on the engine mounts. With a 100k miles replace all the engine/trans mounts.
