All of a sudden, with no reason whatsoever, my daughter's car has "rod knock" with less than 100,000 miles on it. Bought this Subaru for my daughter so she would have a car that would last a long time and she would be safe. Maintenance was kept up at our local mechanic religiously. I am saddened and disappointed in the mechanical performance of this vehicle. Started with lights going out early in ownership when it was new, and now this. I have a Subaru Impreza as well and am strongly considering trading it in for a Honda. I have family that works for Subaru and I wanted to support family and bought 2 Impreza's based on belief that your brand was highly regarded for longevity and safety. Engine's in vehicles should last more than 100k miles, regardless of the manufacturer. This should be a recall based on internet research. My ask is that Subaru stands up to its marketing and its product and takes care of this repair at no cost.

The contact owns a 2015 SUBARU Impreza. The contact stated that the vehicle's check engine light was illuminated and they began to notice at an oil change that their vehicle was leaking excessive oil consumption a year ago. The contact took the vehicle to the dealer who informed them they needed to rebuild the engine. The repair was covered under warranty. The contact stated that about a year after the vehicle's check engine light had illuminated again. The contact returned the vehicle to the dealer who stated that the short block caused the failure. The vehicle had been there for approximately 4 months and had not been repaired. The contact was told the repair was no longer covered under warranty. The manufacturer was made aware and opened a case regarding the matter. The approximate failure mileage was 101,000.

A BAD OIL VALVE IN THE ENGINE TRIPPED THE CHECK ENGINE LIGHT UPON STARTING THE CAR. THE BAD VALVE WAS POSSIBLY LETTING SLUDGE GET INTO THE ENGINE. AT ONLY 60K ANDWITH DOING RELIGIOUS OIL CHANGES ON TIME, THIS APPEARS TO BE A DEFECTIVE PART FOR WHICH A SERVICE BULLETIN BUT NOT A RECALL HAS BEEN ISSUED.

I HAVE A 2015 SUBARU IMPREZA WITH 31,000 MILES (OUT OF WARRANTYDUE TO AGE). THECAR HAS DEVELOPED A SMALL OIL LEAK FROM THE CAM CARRIER COVER (AKA VALVE COVER) ONTO THE EXHAUST MANIFOLD AND THE O2 SENSOR CAUSING A LOT OF SMOKE THAT THEN ENTERS THE CABIN. SUBARU'S ESTIMATE $4973.87. READING SUBARU FORUMS I'VE COME TO DISCOVER THAT THIS IS A PRETTY COMMON PROBLEM IN VEHICLES DATING BETWEEN 2012 AND 2017. DUE TO THE SMOKE IT CREATES IN THE CABIN, AND THE HEALTH RISKS THERE IN, AND THE SHORT LIFE OF THE PART IN QUESTION, I'D RECOMMEND A RECALL BE ISSUED.

SOON AFTER DELIVERY, THERE WAS A NOTICEABLE LAG ( 2-20 SECONDS) BETWEEN THE TIME THE ACCELERATOR WAS DEPRESSED AND WHEN THE VEHICLE ACCELERATED. AT TIMES THIS LEAD TO DANGEROUS SITUATIONS. DEALER SAID THERE WAS NO PROBLEM. THE ACCELERATOR MODULE WAS REPLACED ( NOT AT DEALER) AND THERE WERE NO PROBLEMS FOR A TIME, NOW THE SAME LAG HAS BEGUN TO OCCUR AT RANDOM TIMES, ESPECIALLY AFTER SLOWING TO LESS THAN 20 MILES PER HOUR. NOTE:-- THIS IS A PROBLEM FOR ONE OF TWO DRIVERS OF THE CAR. APPARENTLY THE POSITION OF THE DRIVER'S FOOT ON THE ACCELERATOR MAKES THE DIFFERENCE. NEVER HAS THIS DRIVER HAD A SIMILAR PROBLEM IN MORE THAN 50 YEARS OF DRIVING ALL TYPES OF VEHICLES ( THIS IS AN ONGOING PROBLEM, NOT A SINGLE OR ISOLATED EVENT.)
