1 Coolant Leaking problem of the 2019 Subaru Forester

Failure Date: 11/30/2020

The engine has oil leaked on the left side which I reported on dealership service last November 30 2020 and was fixed and repaired at December 8, 2020. I sometimes check and pop up the hood to see the levels of wiper washer, coolant, and other fluids at least twice a month and noticed last week March 4 that there is again oil leaked on the same left side of the engine. I called the dealership to schedule service and the car was brought again yesterday to have it fix. It is only three months or maybe less coz I did not check the engine last 2 weeks of February due to cold snowy weather. My worry is that the warranty will end this November of 2021 and oil leaked on engine will come back all over again and even after the warranty.

2 Coolant Leaking problem of the 2015 Subaru Forester

Failure Date: 05/24/2019

I have had my Forester since Nov 2014, and during the time of owning the vehicle I have had to add a quart of oil roughly every 2500-3000 miles in between services (5000 mile service interval) as the check engine oil level light illuminates. At two points that I have had the vehicle (roughly 50000 and 80000), I have had oil consumption tests run on the vehicle, both were returned as normal, and that the amount of oil consumed by the engine was within the parameters of the design. On 24 may 2019, I turned the vehicle in to a Subaru dealership in hawaii for servicing (have used this location in the past), and they informed me that the oil is leaking into the coolant system inside the engine, and that the engine needs to be pulled and the upper oil pan seals and head gaskets need to be replaced. I fail to understand how this issue could go undiagnosed for the entirety that I have been having the vehicle serviced at Subaru dealerships, through two oil consumption tests, and just now the issue was diagnosed. I also understand that the amount of oil missing from the pan might not have been "consumed" as the service technician made a point to state, but I would say a pretty good indicator of an issue with the oil system, is the system losing oil. Also, after a cursory search of internet forums, this issue seems to be a common trend among Subaru Foresters, and the symptoms were covered in a similar technical service bulletin (TSB no. 02-157-14r), which includes my year, make, and model, but differs in that it only covers the manual transmission cars, not vehicles equipped with the cvt.

3 Coolant Leaking problem of the 2007 Subaru Forester

Failure Date: 04/14/2014

Both cylinder head gaskets leak oil and coolant. All hoses are brittle. The dealer estimates $3000 dollars for repair. The vehicle has 60000 mile power train warranty. Subaru customer service has offered $500 assistance which is too low. Do other Subaru Forester owners have reported similar issues?.

4 Coolant Leaking problem of the 2003 Subaru Forester

Failure Date: 07/02/2012

As I was driving the check engine light came on for the first time - it is now on continuously due to fuel cap. I pulled over at a service station only to realize my oil was next to empty. I promptly filled and continued the final half hour to my destination. Upon arrival I inspected the engine from under the hood & below the car. It was at this time I noticed build up and fluid around both head gaskets. Initially there was oil residue only, now, 18 months later I have coolant and oil leakage & cannot afford to spend the $1800 I have been quoted to replace the head gaskets. Very disappointed in Subaru for not handling this in a better way. My brother has the same car (year make & model) and has similar issues at fewer miles. My parents have a 2008 outback and had their head gaskets fail at 54,000 miles. Unacceptable. I enjoy everything about my Subaru except for the excessive amount it will cost to fix such a common design flaw.

5 Coolant Leaking problem of the 2010 Subaru Forester

Failure Date: 10/14/2010

The contact owns a 2010 Subaru Forester. The contact stated that while driving approximately 60 mph, she noticed that the temperature gauge was displaying a high reading and the temperature light began to illuminate on the instrument panel. In addition, the contact could also smell a burning odor. The vehicle was towed to an authorized dealer, where the technicians stated that a bolt came loose in the engine while the vehicle was being manufactured. As a result, the engine overheated. Also, there was an engine coolant leak. The technicians replaced the engine short block. The approximate failure mileage was 1,412.

6 Coolant Leaking problem of the 2003 Subaru Forester

Failure Date: 08/21/2009

My 2003 Subaru Forester - purchased new - currently has 55,000 miles on it. It was last serviced 3 months ago. At that time, nothing was mentioned about coolant problems or leaks. Last week, on the turnpike, the rpm needle started swinging wildly and I lost power. I managed to get to the shoulder of the turnpike and shut down and by that time smoke was pouring out from the engine. The problem diagnosed is that the coolant had leaked at the head gaskets - a problem that I am now learning Subaru has known about for some time. I have to replace the engine at a cost of at least $2600. I was never contacted by Subaru or the dealership to inform me that this may be a problem although I consistently have received notifications about repurchasing an extended warranty. Obviously, a 2003 vehicle with 55,000 miles on it has not been driven excessively. Comments I have heard are that "you're still breaking in the engine".

7 Coolant Leaking problem of the 2003 Subaru Forester

Failure Date: 02/19/2009

I purchased a new Subaru Forester xs in July 2003 and had it serviced regularly at now defunct Subaru dealerships. While I was driving one day, the car suddenly overheated. The foreign and domestic auto service mechanic I was able to reach showed me that the engine was leaking coolant in 3 places, requiring a costly repair of the head gasket. I learned from him that this head gasket failure was a common problem with Subarus. I had the car under warranty with Subaru for 60,000 miles. At no time was I notified by the dealer from whom I purchased the car or by any Subaru service center, that special coolant was required to mitigate this defect. I had the car repaired at a cost of over $2,000.

8 Coolant Leaking problem of the 2003 Subaru Forester

Failure Date: 01/27/2007

Dealer advised the head gasket is leaking coolant and recommended repair which will require extensive labor. Vehicle only has 69,000 miles. Vehicle was purchased 20 Nov 2002 and had a 60,000 mile/5 year power train warranty. Servicing was done on a regular basis and vehicle has not been driven excessively.

9 Coolant Leaking problem of the 1999 Subaru Forester

Failure Date: 07/28/2006

We have a 1999 Subaru Forester with a 2. 5 l engine. We got a recall notice 2-2004 regarding external coolant leaks at the engine cylinder head gaskets. This recall covered vehicle years 1999-2002 or 4 years of vehicles. We took the vehicle in and had the specific (special conditioner) installed as required by Subaru. Unfortunately for us it took Subaru 5 years to acknowledge the problem as we are on the front end of the model years in question. Last week the head gaskets failed and with it a large repair bill. Subaru will not honor the extended warranty as we are outside it by less than 10% in mileage but within the specified 8 years in age. We live in southern California and it is our opinion the mileage amounts allowed do not represent this part of the country and are not real world. We have discussed the issue with 2 extremely experienced mechanics including a Nissan mechanic (noted throughout the country) who indicated the conditioner was merely a band-aid, a way for Subaru to make a temporary fix, and not make a proper repair by replacing the defective head gaskets in question.

10 Coolant Leaking problem of the 2000 Subaru Forester

Failure Date: 02/22/2006

Letter received from Subaru March 2004 stating that a cooling system conditioner needs to be added to the cooling system to prevent an external coolant leak at the vehicle's engine cylinder head gaskets. Went to Subaru as required by letter March 9, 2004, they add cooling system conditioner and I am told this will prevent leaks at the engine cylinder head gaskets and this is stated in the letter too. Note that the first time, I receive this notice is 4 years after purchase. The most recent service, I had done by annapolis Subaru was the coolant system service in November 2005. It is February 2006 and my car needs a cylinder head gasket. According to service department at herb gordon Subaru, the consequences of not replacing the cylinder head gasket is engine failure. Engine failure is a safety risk. At no point are you warned that your engine may stop operating while driving. This is a costly repair. I am told that Subaru will pay for this repair if your car has less than 100,000 miles. My car is well maintained and has 132,297 miles on it. The service person then tells me that the head gasket was redesigned by Subaru to prevent this issue from happening again. Subaru is responsible for designing a faulty head gasket on brand new automobiles, where is the mandatory recall?.

Dealer was only flushing the system, and was unable to remedy the problem. Also, yokohama tires that were under the proper inflation for the vehicle caused it to slip and slide even though it was all wheel drive.
