2016 Toyota Tacoma engine problems

“Bought 2016 Tacoma in 2022 w/ 53k miles. Hit 58,850 (ish) and had an noticable oil leak… apparently this was a “Well Known” issue, as the mechanic @ Surprise, AZ Dealership (Toyota of Surprise, 13543 N. Auto Show Ave., Surprise, AZ 85388) told my wife and I…. it’s from this same thing that google showed me also: “Engine oil leaks: Reports on Consumer Reports and other forums detail expensive repairs to fix oil leaks from the front seal or timing cover, which can cost $5,000 or more because the engine often needs to be removed for the repair.” And this was 100% my case- and confirmed by the Toyota Dealers Mechanic verbally. Leaks were without engine light indicators “at all”. The dealership added a dye, told me to drive 100-500 miles and return to have a re-inspection done after their initial one came with no results. Initially I spotted this while I was conducting a regular 3,000 mile oil change. (2nd oil change since owning the truck. So my out of pocket was around $5,700+, for an apparent (see attached) “well-known” Dealer issue. @ 60k, a major repair cost for this should NOT but coming from the consumer, and needs to be listed as a “recall”. Had I not…”

“I have experienced two major failures on my 2016 Toyota Tacoma TRD Sport with less than 90,000 miles: a leaking coolant crossover pipe, which required partial engine disassembly and cost me approximately $2,500, and a leaking timing chain cover, which required a full front-end teardown and cost over $4,500. Both issues are known problems across 2016+ Tacoma models with the 3.5L V6 (2GR-FKS engine), yet Toyota has not issued a recall or warranty enhancement. These failures present safety risks related to overheating and oil loss and result in significant financial burden to owners. Toyota needs to be held accountable for these premature, design-related failures.”

“Upper Intake manifold flap actuator ( part: Toyota 17190-0P101 ) brakes in the intake resulting in wrong air reading and forcing vehicle into limp mode causing the vehicle to rapidly decrease speed, and creating a potential accident with other vehicles and semi's. this will continue to happen but this will give a person a false sense of security since error codes will reset once vehicle is turned off and on, a reassurance to a person that the issue has resolved itself since this will only happen at high speeds. the part is designed for fuel efficiency, as the flap opens and closes air is controlled properly for emission, but once broken will throw error codes, and force vehicle into limp mode this part is not be repairable, the part needs to be changed completely. this would happen to me while accelerating on highways, up mountain passes and pushing vehicle over 4000 rpm.”

“Fuel injector(s) leaked without any warning, causing engine to loose power on freeway. We were fortunate to be able to move over to the shoulder before the truck lost all power. Vehicle was towed to dealer and it was determined that the injector leaked fuel into engine causing engine failure. Repairs needed include engine block, heads sub assembly, injectors and assorted other parts total for parts and labor $19,256 No warning lights or symptoms prior to this problem. Truck has been running fine with no problems, only has 41,000 miles.”

“Vehicle is designed in such a way as to allow moisture accumulating in drivers side floor mat and carpeting to wick upward and be deposited on the primary vehicle wiring harness located in the drivers side kick panel. The moisture collected travels down into the backside of the various female connectors and corrodes the conductors and receptacles that result in short circuits between the various vehicle components including the ignition, engine shutoff, temperature sensors, Antilock Breaking, Blind Spot Monitoring, Fuel Gauge, Forward Vehicle Lighting (high and low beam), Security, Traction Control and other critical vehicle systems. On February 5th, 2023 I returned to my vehicle to find the security alarm sounding in the parking lot of a local business, both the keyless entry system and key-fob were unresponsive and would neither silence the alarm or unlock the vehicle. After manually unlocking the door handle the alarm ceased, the vehicle started as normal and then began indicating a failure of the BSM system, while underway the ABS indicated it had also failed and upon arrival at our destination the engine would not turn off even with the emergency shutdown…”

“This vehicle is equipped with Toyota V6 Motor that was new in 2016. The issue is the Timing Chain Cover leaks oil. This was an issue on Toyota Motors before 2016 and Toyota issued a TSB for those. However Toyota has refused to acknowledge this ongoing issue in its post 2016 Motors. This is a very well know issue by Toyota.”
