I just had my car in for service, one of my issues was vibration in steering wheel when I back up at low speed.
I also complained, about roof rattle, hard shifting, smelly fumes out of AC, chips on my bumper, and brakes grinding at high speed. I took info from this site and alldata.com and gave them TSB's on every complaint. The service writer say that was a big help.
Vibration and hard shifting is gone, they did a reprogramming on transmition better responce from pedal and smooth shifting.
Roof Rattle -- Gone - took down headliner,added foam between sun roof and overhead console.
Chips on bumper -- They touched it up, and gave me a touch up pen (no charge).
Smelly fumes from ac to outside air -- they change cabin filter with HEPA filter. ( havent tested this yet).
Brakes-- resurfaced front rotors and replaced pads with Dura-last pads. So far so good. -- They told me to keep an eye on this if it still happens bring it back.
They also did a ECM -reprogramming and changed my oil they did not use bulk oil as I requested.
And they owe me a car wash -- So far so good.
Since we keep getting multiple threads on this topic, thought it would be best to make a sticky so we can get all information in one place. So any of the "common" steering/front suspension issues you may have should be discussed in here.
These issues can be front end clunks, rattles, odd noises, weird steering sensations etc.
For reference, here is the old thread on the topic.
