2011 Subaru Impreza. Consumer writes in regards to a faulty transmission clutch. The consumer noticed on cold starts and especially if it was cold and/or rainy the throw out bearing would have a consistent squeal. Once the vehicle was warmed up and operating temperature was reached, the noise would subside. At 50,000 miles, the consumer went to another dealership and an inspection revealed the clutch was worn. The consumer was informed it was normal. At the same time, the consumer had an issue with the 5th gear grinding and not being able to put the vehicle into gear without it grinding. A faulty transmission part was replaced under warranty, also, the power steering rack failed and had to be replaced. Seven thousand miles later, the same noise in the throw out bearing had returned.

3 times my engine has needed a short block replacement. I have brought car in for all scheduled maintenance and have changed the oil every 3500-4000 miles. The first engine problem occurred at 26,250 mi. I noticed a knocking sound and brought to Subaru dealer. Diagnosis: "bearing damage to connecting rod bearing for cylinder 2. " short block replaced, under warranty. (see docs) 2nd incident occurred at 51,232 miles. This time there was no warning and I was on an interstate when the engine seized and all power was lost. Towed to a Subaru dealer. No diagnosis was given at that time but short block was again replaced. This time I had to pay for the teardown ($222) but Subaru, after numerous phone calls agreed to do the work as a "good will gesture. " (see docs) the 3rd & last malfunction occurred at 58,700 miles, a mere 7,000 miles since the last engine was replaced. Again, I was on the interstate and with a moments notice (reduction in power) the engine seized. It was sheer luck that I was not killed trying to move over 6 lanes with no power or steering to get off the highway. Towed to a Subaru dealer. I do not have any paperwork from this last incident. Subaru said they would pay for entire repair. But before I could make an informed decision, I asked for written documentation of the problem, cause and a detailed repair description. I have not received this information & did not give consent to repair car. Just got a call from the dealer saying car was repaired and ready for pickup. The only information I have regarding this last seizure was from a Subaru of America customer services rep who verbally told me that "the cylinder 4 rod was thrown. " the car is currently at the dealer. There is something seriously wrong when a vehicle with only 58000 miles needs 3 engines. I refuse to drive this vehicle again. I will not jeopardize my life and of those around me.

Engine knock sound while traveling on highway, pulled off next exit and car shut down. No check engine lights or oil lights indicating an issue. Upon restart knocking sound was louder and had a metal sound to it. I immediately shut the car off and called roadside assistance and had the car towed to local dealer. Upon first review dealer identified it as "internal connecting-rod bearing failure" which caused catastrophic engine damage. Subaru of America denied the repair due to the ecm being modified, stating "our engineers reviewed your file and deemed it to be caused by the ecm modification". I have found numerous cases of the exact issue on the internet, as well as a my dealership telling me there is a TSB for this failure. Soa is providing a "one time good faith repair" but I am responsible to replace the ecm. In my opinion this issue which soa is aware of and acknowledges with a TSB should be a recall - the engine failure at highway speed has potential to cause bodily harm - loss of power, engine seize resulting in an accident. I was lucky to not be involved in any sort of accident. Further I am totally unsure of how soa can claim the failure was due to ecm modification without ever physically seeing or having the motor pulled from the vehicle. The ecm modification is an excuse to not fully cover the repair.

2009 Impreza wrx there was no indication that a failure was going to occur before it happened. I had driven the car normally for almost 4 months. The engine began to make a loud knocking noise around 2000 rpm, sounding like metal hitting metal as I pulled up to a stop sign. Fortunately I had just entered my neighborhood so I was able to get home and have my car towed. Subaru road side assistance towed the car and I was given a rental for 20 days. Subaru dealer said it was a spun rod bearing and engine needed to be replaced. Even though I requested a long block replacement I only got a short block, so the turbo is the same. Since this occurred I have had numerous other problems, clutch throwout bearing replacement, starter, air conditioning problems. This car is a lemon but its impossible to convince Subaru of that fact. Engine blown at 3300 miles. Clutch problem at 7000 miles. Starter failure at 9600 miles (2/2011). Reported to soa.
