This is a second complaint for the same vehicle. Complaint number 11770400, filed today, understated the failure history, and I am filing this one so the complete record is in the database. Vehicle: 2017 Ford Explorer Platinum, 3.5L EcoBoost V6, VIN [XXX]. The first turbocharger failure occurred in 2023, at under 110,000 miles, and was repaired at a cost of approximately $2,900. A turbocharger was replaced again in August 2025 at a cost of $2,895. The catalytic converter was replaced in March 2026 at a cost of $1,700. The internal water pump, which sits inside the engine and is driven by the timing chain, was replaced in April 2026 at a cost of $2,350. On [XXX], at about 138,000 miles, the turbochargers failed again, with loss of power and thick white smoke from burning oil, and the vehicle is now undrivable with both turbochargers in question. Major repairs total roughly $9,800 since 2023, with $6,945 of that in the last thirteen months alone. This is a repeating failure of the same components, and it matches the turbocharger oil supply tube defect described in recall 16V925000 for this same engine. Ford limited that recall to 1,352 vehicles, and my VIN falls outside it. Other owners of 2016 and 2017 Explorers report the identical failure outside the recall window, repeat failures after replacement, and turbo failures damaging their catalytic converters. I ask the agency to consider this complete history, and the pattern of identical complaints, in deciding whether to open an investigation, expand the recall, and compensate the affected customers.

Exhaust Odor in Passenger Cab
During the EA17-002 investigation, the agency reviewed and analyzed reports of exhaust odors in the passenger cabins of Model Year 2011 to 2017 Ford Explorers. This investigation required an approach that incorporated knowledge and expertise from the automotive, medical, environmental health, and occupational safety fields. The agency conducted an in-depth investigation that encompassed the review of over 6,500 consumer complaints, conducting field inspections, and testing the relevant vehicles, both independently and in coordination with Ford and other entities. During the investigation, the evolution of Ford service bulletins intended to reduce the level of exhaust odors and carbon monoxide (CO) entering the occupant compartment was examined and independent tests to evaluate the effectiveness of the final Field Service Actions (FSA) for both consumer and police vehicles were conducted. As part of the investigation, the agency also examined the effects of cracked exhaust mani-cats on the measured CO levels in the vehicles and tested the FSA repairs to ensure they did not adversely impact occupant compartment CO levels due to cracked mani-cats.The investigation identified upfitting issues for Police Interceptor vehicles. Upfitting (sirens, lights, cages, auxiliary power, etc.) is typically performed by governmental fleet operations, independent repair facilities, or local Ford dealers after the sale of the new vehicle. Sealing issues caused by upfitting were responsible for the highest measured carbon monoxide levels in tested vehicles. The police FSA instructs how to inspect the quality of the vehicle upfits and how to properly seal any leaks caused by these upfits, at no cost to the police agency. Similarly, the highest CO levels measured in consumer vehicles were usually traced to sealing issues caused by rear crash damage where the repairs did not ensure sealing integrity. The most recent Ford FSA procedure for both the police (17B25) and consumer vehicles (17N03) includes an HVAC reprogramming operation. Tests by Ford and the federal safety agency have demonstrated a substantial reduction of CO levels due solely to the HVAC reprogramming. Other FSA repairs also demonstrated measurable contributions to CO level reductions during controlled tests.Throughout the investigation, vehicles accurately measured with higher levels of carbon monoxide were almost always affected by upfitter alterations, damage, or other causes compromising rear passenger cabin seals.the federal safety agency received thousands of reports alleging odors which triggered a variety of physiological responses, predominately nausea, headaches, and lightheadedness. the federal safety agency focused the investigation on accurately measuring vehicle CO levels, and accurately measuring carboxyhemoglobin (COHB) levels from properly administered blood tests. Using rigorous test methods to produce exhaust gas intrusion in vehicles with a properly performed FSA, occupant compartment CO levels remained below current environmental limits for CO in any environment (EPA ambient air quality standards). Furthermore, even without FSA repairs, no vehicles unaffected by upfitter issues or prior crash damage were identified with CO levels that exceed accepted occupational CO exposure levels. This investigation finds that the 2011-2017 Ford Explorer vehicles when accurately measured produce occupant compartment CO levels which fall below current accepted health standards, and could not identify COHB levels for vehicle drivers or other occupants, which exceeded thresholds for acute physiological effects. Therefore, the agency has not identified a defect that represents an unreasonable risk to motor vehicle safety.This inve

What 2017 Ford Explorer owners say
Most recent owner complaints, unedited.
Both turbochargers on my 2017 Ford Explorer Platinum with the 3.5L EcoBoost V6 have failed. The first turbocharger failed and was replaced in 2025. On August 10, 2026, at about 138,000 miles, the second turbocharger failed: the vehicle lost power and poured thick white smoke from the exhaust as engine oil burned off, making it undrivable. Sudden power loss and heavy smoke while driving are serious safety hazards. This failure is consistent with the turbocharger oil supply tube defect in the federal safety agency recall 16V925000 for this same 3.5L EcoBoost engine, but my VIN falls outside that recall's range. I ask the federal safety agency to investigate turbocharger failures on 2016-2017 Ford Explorer Sport and Platinum models with the 3.5L EcoBoost and consider expanding the recall, and I ask Ford to provide reimbursement or support for these repeated failures.
Sudden catastrophic engine failure due to coolant mixing. This resulted in a safety issue due to time and location of the event. From online consumer reports this event happens just after 100,000 miles to the 2017 Ford Explorer SUV's and is a KNOWN event that Ford has NOT disclosed. Regular maintenance can NOT prevent this event and stopping the use of the vehicle only helps if it is immediate and the problem known. That Ford hasn't disclosed this possibility of failure nor suggested preventative measures is a safety concern.
Engine hesitated, kept hesitating/slowing down until 2017 Ford Explorer just stopped. Towed SUV to Koons Ford Service Center. Charged $200 for diagnostic assessment. Informed that oil/coolant mix due to water pump failure. Diagnose: replace Engine Long Block and Hardware and thermostat. Costing $11,195.04 for job. Never mentioned what happened to cause this. At another dealership, mechanic told us of the federal safety agency Recall 25V685000 regarding this malfunction. Note: Koons Ford has had a "history" with this SUV, only working on recalls when we push the issue. Also, requiring a $200 diagnostic charge each time the vehicle is seen. This location is where we bought the vehicle.
The contact owns a 2017 Ford Explorer. The contact stated that while driving 70 MPH on the interstate, the engine light illuminated and the vehicle stopped in the middle lane. The contact was able to maneuver and coasted the vehicle over to the side of the road. The instrument panel was illuminated afterwards. The contact stated that the failure was like the federal safety agency Action Number: DP26008 (Engine and Engine Cooling). The vehicle was towed by Firestone and then towed to the local dealer, where the engine was replaced. The manufacturer was contacted, and two letters were sent, three emails were sent to the CEO, and two phone calls were made to Ford Customer Service, who opened a case, but no further assistance was provided. The failure mileage was 55,000.
Driving down the highway and checkengine light came on when I was headed to work. The vehicle lost power due to misfire with engine. I check the spark plugs and there is oil all over sparkplugs and the coil packs. This is a serious issue and needs to be addressed by ford immediately, they need to put a new engine in or pay me to get this fixed.
A strong exhaust smell comes through the cabin during acceleration at speeds higher than 35 mph. Worries us for possible co2 exposure coming through if exhaust smell can come through. But ford dealership has said it passes the recall standards. Still uneasy
The contact owns a 2017 Ford Explorer. The contact stated that while driving at an undisclosed speed, there was smoke coming from underneath the hood with the Check Engine warning light illuminated. The vehicle was driven to the shoulder of the road, and the contact inspected the vehicle and became aware of smoke coming from underneath the vehicle. The failure reoccurred while the contact and the contact's minor children were traveling. A nearby Police Officer assisted the contact. The contact informed the officer that the vehicle was recently purchased from a CarMax. The contact was advised to take the vehicle to the nearby CarMax. The vehicle was taken to CarMax, where the vehicle was diagnosed with engine failure. The contact was informed that the engine had severe fluid leaks. The vehicle was repaired. The vehicle was shipped back to the residence a month later. The failure reoccurred and was a persistent failure. The contact stated that the vehicle was taken back to CarMax twelve times due to the failure. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 86,000.
Car was running fine then went to start and received warning about car being too hot. Checked coolant and it was low. Refilled and drove home. Upon arriving engine light came on. PO301 code. There was coolant intrusion into the cylinders, leading to engine failure. Rough idle when starting. Did not drive after this. Went to start and car will not start at all. Symptoms include: Coolant loss with no visible leaks White exhaust smoke Rough idle or misfires P0300 / P0301 / P0302 codes Hydro-locked or destroyed engines
I’ve had three transmissions replaced from 2023 to 2026. Ford no longer makes 2017 Ford Explorer transmissions so I keep getting bad parts. In 2026 engine light came on , coolant leaking into cylinders, $11K to fix. This car has left me stranded on the side of the road , not to mention months at the dealership trying to find transmission parts. Ford Corporation refuses to buy back vehicle based on lemon law. Rear seatbelts defective.
