Failed coolant control valve and months-long wait for replacement part. Error code P1098. Service center informs us that the parts shortage is nation-wide. We must frequently monitor the engine temperature, which distracts from attentive driving.
Engine Coolant Control Valve sticking and causing the fan to run continuously. (P1098). Seems to be an issue with several people.
Had p1098 code come up on car at 67000 issue coolant control valve assembly went bad. This a commons issue with trailblazers and other cars similar to it. Bad design cause extremely expensive repair for this component.
The contact owns a 2021 GMC Acadia. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. In addition, the coolant fan was running after the engine was turned off. The vehicle was taken to Auto Zone to be diagnosed due to the check engine warning light being illuminated. The contact was informed that DTC: P1098; was retrieved, which indicated a fault with the coolant control valve. The vehicle was taken to the dealer, where it was confirmed that the coolant control valve had failed. The vehicle remained at the dealer unrepaired. The contact related the failure to the Manufacturer Recall Number: N252508341. However, the VIN was not included…
P1098 code indicating stuck/ unresponsive engine coolant control valve. N252508341 exists for this part; however claim is my VIN is not covered under the bulletin or included on any standard warranty coverage. Part should last more than 150k miles, vehicle less than 90k. Less than 2 weeks ago suffered a complete EBPV failure that destroyed coolant and DEF lines, also not covered. No explanation for why my specific VIN (a 3.0L diesel in the supposedly covered MY) is excluded. Have been unable to find evidence of any applicable vehicles that were 'covered' under this bulletin. Fault forces an unexpected derate which can engage while accelerating, including while merging into freeway traffic…
Was driving at highway speeds when truck shuttered and rattled and quickly slowing down. Warning errors on dash stated "Reduced Acceleration, Drive with Care", "Service Emissions System", "Service Traction Control", "Service ESC". Got vehicle to dealer and they confirmed the error code (P0202 - covered under powertrain warranty), but then also noted an error code for P129F where the truck would not start up. They are recommending a replacement of the Fuel Pump Power Control Module. GM had updated a NHTSA bulletin (original: N262558690 - Emissions Recall - Fuel Pump Power Control Module - July 15, 2026) on August 12, 2026 that expanded the population of qualified models to include the 2022…
Check engine light with P1098 code for engine coolant control valve failure. This part has been on back order for months and manufacturer hasn’t declared a recall or provide any update to their customers.
Our Chevrolet suburban has 57,000 miles on it. We have started getting a check engine light and I’m getting code P1098 for the cooling control valve. This is a very common issue on these vehicles I’m noticing now. From what I’m reading in February of this year (2025) gm gave this issue an e code so these valves would no longer be covered pay the powertrain and they would now fall under emissions for a much shorter warranty coverage. This has been and ongoing issue since 2020. These valves are also commonly found to be on national back order causing long lead times and driving of the vehicles without properly functioning. GM knows these are and issue and shortening the warranty is not the…
P1098: questions drivers ask
What does code P1098 mean?

Is there a recall for code P1098?
No NHTSA recall text names P1098 directly. 1 recall on the cars that report this code concerns the same component owners name most (Engine); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P1098?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
