Since day one, the clutch has shuddered at engagement when engine/drivetrain is cold. The tremors are violent enough to shake the entire vehicle disturbingly. This has been a nuisance and somewhat of a safety issue as you cannot accelerate quickly if necessary. Over the last 10000 miles or so, I've noticed a burning smell when engaging the clutch on an uphill start. Dealership says the clutch is slipping and will need replacement soon and I only have 61500 highway miles on the car! I've had plenty of cars go over 150000 miles with no clutch problems. Subaru has a definite design flaw in these hydraulic clutches that they are refusing to own up to! Regrettably, I May have purchased my last Subaru.
Starting around 62K miles, I heard a whining noise from the front of the car. The noise got louder and higher with wheel speed. When I took it to a mechanic, they diagnosed a bad differential bearing, and informed me that the recommended fix was replacement of the entire transmission, including both differentials. When I went to the dealer to confirm this, they quoted me $6,000-$8,000 for the repair. I tried to get some relief from Subaru of America, since the powertrain warranty goes for 60K miles, but they were unwilling. This caused the value of my car to go to zero, since it's worth about $8,000 without the transmission problem.
The automatic transmission park mechanism does not engage properly. With selector lever in "park " and car turned off and ignition key removed, the car rolls. In the early years, the car rolled only slightly and finally "engaged": now, the car rolls several feet and does not always engage, requiring use of the emergency brake for all parking. Because the problem is getting worse, we searched for repair & recall information. We found that although our model & year are on the recall list for this park mechanism, our VIN# is not.
Tl contact owns a 2001 Subaru Outback. While driving approximately 30 MPH, the contact heard a loud clicking noise and then the vehicle stalled. He noticed that the transmission had fallen out of the vehicle onto the road. The vehicle was towed to his residence. He is in the process of notifying the dealer to determine the cause of the failure. The failure and current mileages were 75,000.
Car has significant hesitation during periods of acceleration, usually around 2500-3500 RPM. Potentially dangerous in many driving situations. Have reported to dealer multiple times. Response is always "cannot reproduce - computer shows operating as designed". Car also has spontaneous acceleration at low speed, such as first taking foot off brake.
Consumers child accidentally bumped the shift mechanism causing vehicle to roll backwards. The keys were not in the ignition when the consumers son bumped into the shift. It was verified that the safety interlock was not operating as designed. (a pin had come disconnected)
Since about 10,000 miles the clutch shudders when trying to accelerate. Usually only when engine is cold but not 100% of the time. Have complained to Subaru dealer but they could not duplicate the problem. Apparently a known problem with some subarus but not all dealers address it.
My 2001 Subaru Outback has a clutch shudder ( jutter ) that is reported to occur in all Subaru models with the 2.5 ltr engine. There are inumerable consumer complaints about the problem and yet Subaru burries its head in the sand and pretends there is no problem.
Clutch shudder problem since 20K miles. Happens when cold or damp out, hesitates when accelerating in first gear, from stopped position. The vehicle was taken to the dealer 3 times, including test drive w/ mechanic,can't find the problem.
Since new, the clutch in this car has had a bad shudder when cold outside -- bad enough to shake the entire car as the clutch engages. It only happens when it's cold, but not all the time when it's cold, making it nigh impossible for the dealer to do anything about it. 20K miles later, the problem still exists for me and apparently many, many other Outback drivers. Internet posts confirm that this is a "common" Subaru problem, although a fix is not readily available. The dealer acknowledges that there are known problems with some legacy/Outback clutches, but until the clutch will reliably fail while they have it, they cannot do anything about it. …
