Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving down the road and the engine stopped producing power. After pulling it over it wouldn't start. Dealership says the engine is toast and it will cost 10k. I have done all the regular maintenance and oil changes. An engine should not need to be replaced at 77k miles. My toyotas have lasted forever.”
NHTSA complaint #10639942, filed 2014-09, 77,000 miles“The clutch bracket on the firewall has only 4 small tack welds from the factory. This bracket takes all the force of your leg pushing in the clutch every time you change a gear. It appears to be very common on the Subaru wrx sti for these small tacks to break away from the firewall and cause accelerated clutch wear and eventually clutch failure. My clutch failed and the dealer is now telling me that there is no knowledge of the problem and the repair for this manufacturing defect will not be covered by Subaru. …”
