2017 Ford Expedition: engine stalls while driving

Filed Jun 23, 2026 · Engine, Transmission · TX

I am reporting a severe, systemic manufacturing defect in the 3.5L EcoBoost engine timing system (cam phasers and timing chain) of my 2017 Ford Expedition that poses an immediate highway safety hazard. Approximately February 2026 Upon start up heard odd rattle type noise, a week later heard noise again thought maybe due to recent Ford Dealership changing engine belts. Searched websites discovered notable issues regarding serious known manufacturing defect, cam phasers, timing chain, water pump. Followed Ford recommendation to change oil well before normal schedule to address. At approximately 54,550 miles, the vehicle began exhibiting continuous mechanical rattling and timing instability upon startup, a condition heavily documented across Ford’s truck/SUV platform and acknowledged internally via Ford Technical Service Bulletin TSB 23-2143. The 3.5L EcoBoost is a high-compression interference engine. A failure or skipped tooth of the timing chain or cam phaser system while operating at high speeds causes instantaneous, catastrophic engine failure. This results in an immediate stall and a complete loss of vacuum-assisted power braking and power steering. This vehicle is routinely operated on major Texas highway corridors (XXX) at posted speeds of 75 mph by my [XXX] spouse, who stands[XXX] and weighs [XXX]. A sudden loss of motive power and mechanical steering/braking assistance at 75 mph presents an unsurmountable vehicle handling emergency that would likely result in a high-speed crash, rollover, or catastrophic multi-vehicle collision, as a driver of her physical stature cannot safely muscle a stalled, unassisted 5,500-pound SUV to the shoulder. To mitigate this imminent risk to human life, I was forced to perform emergency out-of-pocket repairs to replace failed factory components with Ford's updated, redesigned parts. This defect represents an inherent, dangerous engineering failure requiring a mandatory federal safety recall before highway fatalities. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

The electronic throttle body gets stuck closed. The engine stalls or goes into limp mode. At highway speed I then have to try and navigate a dead car to the shoulder or am stuck in the middle lane with cars going past at 70+ mph. This is a known defect in fords engine and other years/models are recalled. 2017 Ford Expedition needs to be added immediately. This is dangerous.

Vehicle started running rough going up a highway on ramp, check engine light came on, pulled over and shut off engine. Restarted engine and it continued to run rough. A couple days later the vehicle stalled while accelerating into an intersection and again the check engine light came on. The electronic throttle body etb assembly has been replaced by the dealer. I feel this is a safety issue, and it should be covered under a recall!
