Is There a Problem with the Heat Exchanger in the Exhaust of the 2022 Ford F-150?

Hundreds of 2022 Ford F-150 Powerboost truck owners are reporting that defective heat exchangers cause leaks that result in coolant draining from the exhaust. They are also finding that because the problem is so widespread, the major back order on parts is causing delays in having the faulty parts replaced.

We are also aware of at least one report of a new, redesigned replacement part failing.

What Exhaust Heat Exchanger Problems are 2022 Ford F-150 Owners Experiencing?

2022 Powerboost truck owners are complaining on forums that coolant levels are dropping, probably because of the exhaust heat exchanger. So far, there has only been one official complaint to the National Highway Traffic Safety Administration (NHTSA), but the issue is exactly the same as those described in forums.

NHTSA Complaint

The NHTSA complaint, filed on March 24, 2022, states, “There is a heat exchanger in the exhaust that leaks coolant and causes the engine to overheat.”

The owner of the vehicle, who is from Pompano Beach in Florida, maintains that this “has happened to over 500+ Powerboost Engines,” citing Ford Case Number: CAS-35641317-W3Y6F0.

Ironically, there is a technical service bulletin (TSB) on file with NHTSA for the 2022 Ford F-150 that relates to engine cooling, but nothing to engine heating. The TSB states that “Some 2015-2022 F-150, 2017-2022 F-Super Duty and 2018-2022 Expedition/Navigator vehicles may exhibit poor air conditioning (A/C) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures.”

Forum Complaints

There are complaints on several F-150 forums including f150gen14.com, f150forum.com, and f150ecoboost.net. Generally, complaints are threefold. Ford F-150 owners are saying:

  1. Coolant is leaking from their trucks, with some having identified the exhaust heat exchanger as the reason
  2. They have been getting check engine light (CEL) P237C warnings
  3. Parts needed to make the repair are on backorder and they’ve been told they won’t be available anytime soon

What Owners Are Saying on Forums

F150forum.com Comments

A member of f150forum.com says on March 23, 2022:

“Took the truck to the dealership today after noticing that the coolant reservoir level was low (Only done 2500 kms from new). Turned out to be the exhaust heat exchanger leaking. Unfortunately, it seems to be a common issue and the parts are on backorder with no definitive timeline for replacement. ALL Powerboost owners, keep a close eye on your coolant reservoir level or any signs of leaks in the center area of the truck.”

Another f150forum.com member says on May 16, 2022:

“Best guess, if the coolant level is slowly dropping, it is likely the exhaust heat exchanger. There have been several reports of leaks on them, so you may be part of that club as well.”

Another member says on June 10, 2022:

“I think we’re all talking about Powerboost here. Mine also had the same issue, where coolant leaks from the exhaust heat scavenging loop used for heating up inside when (the) gas engine is off, but (the) car is running in EV mode.

“The solution is replacing that whole exhaust piece, and my part was shipped this week to the dealer. The new part has a new revision number, so I’m hoping (the) new part will permanently resolve it.”

F150gen14.com Comments

In response to another member’s comment that the situation is “discouraging as heck”:

“Yep. And I have not used the heat once in this timeframe. Just the A/C.

“My dealership has been incredibly helpful though. They topped off my fluid and said I could keep the truck this time. They also are filing a case with corporate and telling them I am threatening arbitration and requesting a buyback. The thing is I really love this truck. If it wasn’t for the issue with the heat exchanger I would have zero complaints. They really need to upgrade the part and use a different material besides plastic.”

Several members mention the CEL P237C for the exhaust heat exchanger, though several say they haven’t had leak issues (yet).

To complicate the issue, one of the comments states, “ I had no leak ever, just started with P237C, then at some point, before I checked codes again a couple weeks later I got P237F, P2C22, and P2C23.”

Clearly, they are all frustrated because there hasn’t been any resolution from Ford.
