While stopped at a stop sign my engine suddenly died, before restarting a low oil pressure light came on but went out immediately. I was approximately 40 miles from home when I got to my destination. The car was showing no signs of issues, no warning lights or errors. When I went back out to start it and head home it would not start. I had to pay additional expense beyond my insurance road side coverage due to the distance. I have had an independent mechanic going over the vehicle since it died. Starter has been replaced because it appeared to be the issue. (the original was bad) Once replaced while attempting to start it he found out the engine had locked up. I bought the vehicle March 30, 2026 & this happened on June 10, 2026. The vehicle had 132,344 miles on it when bought and 135,716 when it seized up. After looking through other reports I have found this to be a reported issue.

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

Ford Explorer Exhaust Odor
During the federal safety agency?s (the federal safety agency?s) investigation into the Ford carbon monoxide allegations, the Office of Defects Investigation (ODI) identified additional Vehicle Owner Questionnaire (VOQ) reports with similar exhaust odor claims.Presently, ODI has identified 791 VOQs for Model Year 2011-2017 Ford Explorers pertaining to exhaust odor claims.ODI has identified three crashes and 41 injuries potentially linked this issue.The reported injuries range from unspecified to loss of consciousness, with the majority being nausea, headaches, or dizziness ? all of which can be symptomatic of carbon monoxide exposure.Additionally, Ford provided 2,400 reports including owner complaints, warranty claims, dealer field reports, and legal claims, that involve 2,051 vehicles that may be connected to the exhaust odor issue.the federal safety agency's Vehicle Test and Research Center tested multiple vehicles, including complaint vehicles, during the investigation.ODI also conducted field inspections of complaint vehicles and crashes involving police units that occurred while the officers were on duty.When possible, data was collected to quantify carbon monoxide levels in the examined vehicles.Based on the information gathered to date, the federal safety agency upgraded this investigation to an Engineering Analysis (EA17-002).

Burnt exhaust smell in cabin after hard acceleration. The smell is overwhelmingly bad causing nose and eye burning and coughing. To remedy the smell the windows have to be rolled down to air out the cabin.
The contact owns a 2011 Ford Explorer. The contact stated that while his daughter was driving at various speeds, the engine overheated. The contact stated that the water pump was leaking, and the contact replaced the water pump himself. No warning lights were illuminated. The contact stated that the vehicle was scanned with an ODB scanner an engine overheating code was retrieved. The contact stated that the radiator cooling fan failed to turn on. The contact stated he had installed a new temperature sensor, but the vehicle was not repaired. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The failure mileage was approximately 200,000.
My son was on the highway and his Ford Explorer 2011 just stopped, he could have been killed! He was able to get off safely and had car towed. Our mechanic told us today it is the Water Pump leakage and we need to take to Ford. We called Ford and they said at least $5,000 to repair possibly more. This is a huge safety concern when the act can just stop dead on highway. There are no safety recalls on this water pump. My son was lucky to make it off the highway alive.
The internal water pump failed in my 2011 Ford Explorer without any warning signs and the coolant then leaked into my engine causing catastrophic engine failure. We were driving on a busy highway and the Ford Explorer simply started shutting down in the left lane. Nothing would happen when I pushed the gas petal and suddenly all the lights started flashing and heat went to above high. I was barely able to get over to the shoulder as smoke started to come out of the front of the engine. We were extremely afraid of getting hit since the car stalled on the highway only feet from the exit ramp. The car was towed and diagnosed at the Ford Dealership: Internal water pump failed causing engine failure - water mixed with oil. The car received state inspection and oil changed 17 days prior. Paid for engine replacement at the Ford Dealership with costs over $11,000.
The contact owns a 2011 Ford Explorer. The contact stated that the low oil pressure warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the engine block was cracked and the oil sending unit was damaged. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under warranty. The failure mileage was approximately 122,000.
