Selected complaints filed with NHTSA by 2016 Toyota Tacoma owners, lightly cleaned up (personal details are redacted by NHTSA).
I have three signifcant issues with my Tacoma: 1. A few months after purchasing my Tacoma in 2016 Toyota (no accidents to date & 95% highway driving) and one outside alignment shop had never been able to get the truck aligned properly so it would never keep its alignment more than 3-4 months; repeated visits to Toyota maintence for alignment over the years became as routine as an oil change, sometimes more frequently; the unaligned suspension constantly was causing unsafe handling and unintentional swerving. 2. Toyota missed, and maybe purposefully, identifying major engine, transfer case, and transmission leaks during regular and routine serivces (always serviced at Toyota dealerships) until my mileage exceeded 60,000 miles. Then when I asked the dealership to recheck a recent transfer case refresh because I saw leaks, I needed and got over $3,000 in repairs e.g. …
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.
There is a known factory defect on a robotic seal around the engine block, in which the robot misses a half inch piece of the engine block, causing oil seepage and leaking of engine oil. The problem is on dozens of Toyota forums and I have also consulted with two different dealerships that have verified this. The 4 cylinder engines in the Tacoma have already been recalled for this issue but they are offering no reimbursement or recall on the 6 cylinder engines. The engine begins leaking oil early in it its life as mine has been. An engine should not fail at 20k 30k or 80k miles due to a factory defect. Toyota should be offering a fix for this issue as it will significantly cut the life of rhe engine. This can cause engine fire and various other safety issues in these trucks if enough engine oil leaks down into a hot engine.
On 11-27-2021 I lost all power while on a highway. I would lose power even with my foot all the way down the rpm would not rise at all. The power would come back adruptly and throw me back into my seat. The trac off and check engine light came on. My truck seemed like it was gonna stall and had a really low and rough idle. It was only about 0-500 rpm at idle and truck was shaking bad because of the engine. After getting towed home I tested the battery and alternator and those were fine. I believe it is the crankshaft position sensor. I have read that this has happened to man other people with the same truck as mine. There was a recall for the cps but for some reason my truck was not included.
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.
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.
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.
driving full speed car suddenly slows and light on dash reads accelerator and brake pressed at same time, although my foot is nowhere near the brake. This is 3rd time it has happened, Toyota say's it doesn't come up as error on their computer.
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. …
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. …
