Hey everyone,
Just wanted to add to and document here that I too have experienced the transmission shudder issue, more so recently than previously. Please allow me to explain…
The first couple of occurrences happened about 4 months ago at around 5K miles. They were fairly minor and happened briefly each of the two times that I remember. I didn’t experience it again at all for another 4 months, so I figured “no problem”.
Recently, I started experiencing transmission shudder again about a little over a month ago, around 9.9K mikes. This time, I experienced multiple shuddering within a two-week period. Some of the occurrences felt like minor transmission shaking/hesitation while others felt violent, to the point that my wife and/or young kids responded with much concern. Being concerned, I informed my service manager (who is very nice… no issues with his service) about it when I brought the car in for its 10K mile maintenance (oil change, tire rotation, etc.). This was about three weeks ago. The service manager had two technicians drive it around, but could not replicate the transmission shudder. The service manager told me that I had the latest TCM software and that nothing seemed out of the ordinary upon inspection. I was told to monitor it and to try to think about the last 30 seconds prior to each occurrence. Since then (within the last three weeks), I have experienced it again numerous times and have observed the following approximate conditions/events as to when the shuddering occurs for me. Here’s my experience through it…
Within approximately 30 seconds before a shudder occurrence, I am typically driving about 25-30 mph on a level or slightly-inclined road/street. In preparation for an upcoming turn that’s about 50-feet ahead (and doesn’t require actually stopping), I brake normally (non-aggressively) and slow down to about 15 mph just before entering the turn. Into the turn, I continue applying the brake pedal and am holding a speed of around 15 mph while cruising through much of the turn. Just coming out of the turn, I then gently (and definitely not aggressively in this case) begin to apply the gas pedal. Keeping light pressure on the gas pedal, I feel the car beginning to slightly pick up speed for only about a second and then, SHUDDER!!!
It feels as if the transmission is hesitating on speeding up again, though it had just slowed down briefly. Of each occurrence, I experienced the shudder for a good 2-3 seconds before I take my foot off the gas pedal completely for a couple of seconds. I then gently press the gas pedal lightly again to resume driving, with no issues (thankfully).
The shuddering doesn’t always occur when the above-described conditions happen. However, when the shuddering occurs, the above-described conditions are what I have observed. (hopefully that made sense?) I don’t recall having experienced shuddering under any other conditions/events. Within each occurrence, I experience the shudder once and it doesn’t occur again after I let off/re-press the gas pedal after the shudder.
I love much about the QX60, with at least one exception being this shuddering issue... it's now getting out of hand. Sometimes I correctly predict that it will occur just before I happen to head into the right conditions… then sometimes it didn’t happened after all (thankfully).
I will e-mail the above the observations to my service manager to get this thoughts. In the meantime, has anyone else experience shuddering per my described observations? If different, then under what conditions did you observe your shuddering?
Thanks,
-Tony
