Power loss issue

[Ates]

Hi everyone,

I have a 2018 Ford Edge 2.0 SEL AWD with around 240,000 km. About a year ago, it started having acceleration issues. Since then, I’ve taken it to the mechanic multiple times and replaced the following parts:

• Spark plugs

• Timing set

• Solenoids

• Turbo

• Catalytic converter

 

Basically, almost everything has been replaced, but unfortunately, the problem still persists. The car struggles especially when going uphill — it revs loudly but never goes over 80–90 km/h.

 

Has anyone experienced something similar? Could this be a transmission issue? Any advice would be greatly appreciated.

Welcome.

 

If you're not a DIY person and reliant on service shops, then search for a reputable shop because the mechanic you've been using is obviously not qualified and throwing parts at it.

 

When you say that it struggles going uphill - is the engine revving high but not changing up to the next gear - the engine revving high should deliver more power until it reaches maximum revs - maybe a video of what's happening will give us a better idea.

 

Get the stored fault codes read and post them here.

What oil and oil filter have you been using?

 

What oil change interval have you been using?

 

I ask those questions because the P0012 and P0299 are typically the result of oil sludge due to lack of maintenance.

 

The P0012 could be the unqualified "mechanic" who did the "Timing Set" got the valve timing off, or sludge has fouled the Variable Valve Timing solenoid.

 

The P0299 is related to the turbo - poor maintenance could also be the cause of that.

 

Again, find yourself a reputable qualified mechanic.

Did you ever get it fixed? I’m having the same issue. It starts out running normally with good acceleration, but after a few minutes on the highway it loses power. I only recently noticed it because most of my driving is in the city, but over the last few months I’ve been driving on the highway more often.

 

I had the coolant intrusion leak repaired last year, and I think this issue started after that repair. Before then, I made several long highway trips without any problems, so this definitely wasn’t happening before

@WillM any codes?

When " something " is changed / repaired, and then almost immediately a problem appears, in many cases the source of the problem is directly related to that repair.

 

Who did the repair and have you spoken to them about this issue?

 

I have had a similar issue years ago on a Ford LTD.  It all of a sudden started acting up like you mentioned.  Thankfully I didn't just start throwing parts at it.

Ultimately, what the problem turned out to be was the fuel filter.  This car had an external fuel filter so it was easy to check.  The fuel filter was loaded down with particles from the fuel tanks from the gas stations.

 

Once the fuel filter was changed, never had the problem again  AND  I was more careful of the gas stations I frequented.

Just something to consider .

I just got the P1016 code. But this only came up after months of when I first encountered loss of power. I first confronted loss of power within a week of having the engine block replaced because of the “coolant intrusions”. I took it to the dealer on Monday and they said they found nothing wrong. I told them that if Im paying for a diagnostic, they better find whats wrong. It could be something as simple as not fastening the vacuum hose when they did the engine block replacement. This is just my guess.

If the engine block was replaced, then obviously everything had to be disconnected and reconnected back again.

 

I presume you looked up the P1016 code and found this:

Search Assistant 

The P1016 code indicates a "Wastegate Control Pressure Higher Than Expected," which typically relates to issues with the turbocharger wastegate solenoid or associated hoses. Common fixes include checking for vacuum leaks, replacing the wastegate solenoid, or inspecting the turbocharger system for restrictions.

As with many codes, there is no one reason / answer to consider to get a resolve.

I also looked just now and found this as well.  There are probably other results, depending on how hard one looks:

 

Key Takeaways

• The P1016 code indicates a fault in the reductant control module sensor serial communication circuit, triggering a high voltage level detection.
• Possible causes include a faulty Reductant Quality Sensor, wiring issues, or a malfunctioning Reductant Control Module.
• Symptoms of the P1016 code include the Engine Light ON and reduced engine performance, potentially leading to difficulty starting the vehicle.
• To fix the code, inspect the related wiring harness and connectors, repair or replace damaged parts, and clear the code to see if it returns.
• Diagnosing the P1016 code requires a thorough understanding of the reductant control module sensor’s serial communication circuit and sensor testing.
