Getting ready to put the Caddy back into the dealer to fix a shudder.
Does anyone else have or has had this problem:
2006 47,000 Miles
Shudder felt at and below firewall with vehicle moving :
1. Full Throttle between 2500 and 4000 RPM - Straight line
2. Half throttle 2500 - 4000 RPM - left turns 15- 60 degree turn
3. Half throttle 2500 - 3500 RPM - left turn 80+ Degrees
I cant find any TSB that fully describes this problem, but there are many other DTS owners that describe having the same issue without a solution. The internet and the forum is full of owners that complain of shudders and they are not out of balance tires I am refering to.
So far replaced
1. Tires three new sets, multiple balancings
2. Strut mounts
3. Control arms and ball joints
4. Upper and lower front engine mounts
5. Right axle
Other Possibilities I am considering:
1. roller surfaces inside the inner cv joint housing,
2. Rear engine mount
3. Improperly tightened (torqued) axle (Wheel)
4 Run out on the hubs or due to corrosion on the hubs causing the rotors to not sit flush
5. Harmonic balancer on the engine
6. Back pressure or loose material in the Catalytic converter
7. Failure in Traction control system
8. Torque converter
Has anyone else FIXED this problem, if so how? If the dealer cannot figure it out next visit, I will take the next step and contact GM, ask that they will send out a rep to drive the car, verify, and figure out the problem.
BTW At this point finding a different dealer will not be the solution, as I am currently working with the second dealer. One Thing I have not done to date is to take a ride with the service advisor, but I am holding that for last as the problem does not always present itself and the advisor ride is usually the final step before calling in Sales service and marketing zone reps.
