Actually ford already come up with improved version of short block which they already remove coolant slit in between piston cavity. This coolant slit design cause the material in between cavity really thin and prone to crack.ย Unfortunately, there is no recall happen. But i do know that some of user already replace with new version block (under warranty), wont face the same issue anymore.
For current mk3.5 user, what we can do is just monitor coolant lever regularly.
The rating 5 out of 5 customer seems doubted. As i know, there are lot of mk3.5 user out there wont have this defect yet.
One of my close mate, already reach mileage 16xk km, without any coolant loss issue.
Design failure is one thing and another also I believe is depends on how we drive our car as well.
I am myself already reach 12xk km. So far so good and of course, i always monitor my coolant closely.
Thanks for information. Good to know that you didn't experience any issue with the vehicle yet (touch wood) after reaching 120,000 km. Yes, I agree that the symptoms with the engine may be closely related with driving style. Premature failure may be experienced earlier with fast and furious driving style.
The 5 out of 5 comment was actually referring to all customers who brought the car to the service centre where the car showed cracked engine block for cylinder no. 2. Meaning, a consistent pattern of the crack which happened at cylinder number 2 and not 1, 3 or 4. From your post, it appears that not all owners have experienced the issue with the cracked engine block yet. Nevertheless, the consistent pattern of failure where some owners have experienced with the mk3.5 ecoboost engine may suggest that the design of the engine block may have been a compromise and not too durable, perhaps more prone to cracking with aggressive driving habits.
Do you have any idea how many years of warranty is provided for this cracking of the engine block? For the mk3, normal warranty period is 3 years but for "design flaw" components such as the dual clutch, if my memory doesn't fail me a longer warranty of up to 8 years was provided. For the TCM the warranty is up to 10 years and defective door latch was replaced under goodwill for free irrespective of age of car (not sure If ford Sime Darby still continue replacing door latches for free though).
May I ask if the Focus mk3.5 have issues with the door latch whereby the door will fail to lock when you try to close it? The mk3 has this door latch issue where it will fail at around 8 years +/-.
