Ford Confirms Some Focus RS Engines Can Develop A Coolant Consumption Issue

Sponsored

If you’ve been following the Ford Focus RS on internet forums, you might come to think that every example ever sold has developed an issue that causes it to consume coolant. The actual share of afflicted RSes is far below 100 percent, of course, but according to Autocar, Ford does indeed acknowledge that the 350-horsepower, 2.3L EcoBoost I4 in the Focus RS is prone to incurring a habit of losing coolant.

The 2.3L EcoBoost four-cylinder in other Ford models, like the Ford Mustang EcoBoost, isn’t believed to be affected. That version of the engine uses a different alloy in its cylinder block and head.

Ford is “working on a repair for all customers,” a spokesperson says. “In the meantime, if vehicles show these symptoms, customers should visit their dealer for an inspection and repair under warranty,” he says.

The issue is thought to stem from how the block expands and contracts through several heat cycles. Engines with as few as 6,000 miles appear to be distorting beyond the accepted tolerance, preventing a proper seal at the headgasket between the block and the head. This allows coolant to enter the combustion chamber and create a white cloud of smoke as it’s burned off, possibly creating a misfire, until the engine warms and the block and head expand to regain an adequate seal.

Let the issue persist for too long, however, and the result could be catastrophic. YouTuber and Focus RS owner MarkCup70 says he came across a dealer report for one car that had developed a warped cylinder head as a result of all the coolant loss, Autocar reports.

    I have a 2018 Ford Escape. I bought it from a used car dealer. I paid my 3rd payment and broke down. Today was diagnosed with the Coolant leaking into the cylinders. I am so crushed!!!! Ford won’t help me because it’s 2000 miles over the 60,000 mile warranty. The dealership won’t help because I bought as is. I can’t afford to pay for a new engine. How can I get in on the lawsuit???? Help me please!!!

    We bought a 2017 ford edge 1.5 yrs ago and have brought it in to dealership many times for issues about the car.. we complained to service about the misfiring and being stuck at gas station or work because it won’t start.

    They have done many oil changes at the ford dealership and should of looked at coolant..A matter of fact they should of told us they had issues with the engine when we bought this car with very low miles.

    We even kept trying to set up an appointment and they said they can’t get us in for a month
    . Which is unacceptable with the issues we were having….

    How do we get into this Law Suit???? I believe our dealership lied and hid this information from us when we bought this ford edge…….now we are being told we have to replace the engine for $9.000.00 that is a scam to us and the consumer…especially that’s all we ever have bought was fords..

    Please help
