Owner Narrative

My 2017 Toyota Highlander, VIN [XXX], has just under 85,000 miles. I was notified at the dealership (Stevinson Toyota in Lakewood Colorado) who inspected the vehicle yesterday that the vehicle has developed a timing cover oil leak on the passenger side. After further research I learned this is caused by premature failure of the factory applied FIPG sealant at the timing cover’s T junction. This is well documented as a known, widespread defect in the V6 engine used across multiple Toyota and Lexus models between 2014 and 2019. This failure is not due to wear, neglect, or misuse. It is the result of a documented manufacturing flaw that requires full engine removal and carries an extremely high repair cost — a burden that should not fall on customers when the underlying cause is a defective sealant application at the time of manufacturing of the vehicle. I was quoted $5400. I am deeply concerned that Toyota has not issued a recall for this problem, despite its prevalence and the clear safety risks it presents. This leak is not merely a “durability issue.” It has legitimate and serious safety implications, including: •The potential for engine fire due to oil contacting hot components •Serpentine belt failure, which can cause sudden loss of power steering, alternator function, and vehicle control •Additional engine damage if the leak worsens •The possibility of the vehicle breaking down in unsafe or remote conditions Any of these outcomes pose a real safety hazard to drivers, passengers, and others on the road. Toyota’s decision not to address this known defect through a recall is extremely disappointing. I have reached out to Brand Engagement and was turned down by a gal named [XXX]. I then escalated the issue and was again turned down by a gal named [XXX]. I firmly believe Toyota should have issued a recall for this known issue costing consumers $5400 to repair a safety issue due to what is documented as a manufacturing defect.
