National Highway Traffic Safety Admin March 9, 2026 I am submitted a vehicle safety complaint regarding a 2011 Subaru that I recently purchased on [[redacted]]. I purchased a used 2011 Subaru Impreza from Clear Cut Auto {241 S Dupont Hghwy - New Castle, DE 1920 (302-322-2050) on [[redacted]] for $5,147.04.

vehicle was sold as "as is". Within three (3) days of purchase the vehicle On Sunday [[redacted]] while my [[redacted]] son was driving on a major highway, the vehicle suddenly showed a engine light which blink on and immediately went out. Thereafter, the car started smoking and was engulfed in flames ie: caught on fire. I am grateful that my [[redacted]] son was able to exit the vehicle safely and quickly to avoid injury. The car was completely destroyed by the result of the fire internally and externally. This created a serious life-threatening safety situation for my [[redacted]] son, which had to exit the vehicle quickly to avoid injury. Multiple people on the highway witnessed the fire. I am concerned that the vehicle sold to me by Clean Cut Auto (owner Lonnie and dealer Erika Fernandez) may have had a serious pre-existing defect involving the engine, electrical system or fuel system that caused the fire while the vehicle was being driven. I am submitting this complaint so that the incident can be investigated as a potential safety defect involving this vehicle model. 2011 Subaru Impreza VIN# [[redacted]] Fire Date: [[redacted]] Registration: [[redacted]] Location: [[redacted]] - [[redacted]] from [[redacted]] 3.04 miles from New Castle Municipality Police Report [[redacted]] Cpl Diprima -Troop 2 State Police 302-834-2620 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

2011 Subaru impreza. Consumer writes in regards to a faulty transmission clutch. *Smd 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.

The car is a 2011 subaru wrx sti. As far as I can tell nothing led up to the failure. It was fine one day, then failed the next. The failure was broken piston ring lands on the #2 and #4 pistons in the engine. The consequences were that I needed to replace the short block of the engine along with all associated parts like new pistons. Subaru replaced the short block and all associated parts under warranty, including new pistons and rings. *Tr

1. Was driving the car and it started to smoke like crazy, and lost power while in the middle of traffic. 2. I had an engine failure, almost 75% of these cars are having the same issue 3. Brought it in for work and the dealer made me pay for it because subaru didn't want to warranty the car! *Tr
