2016 Toyota Tacoma Engine Problems

Rear Coolant Bypass Joint leak. Coolant leaking through this pipe and accumulating.

Coolant leaking

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.

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 noticed the missing oil, this could have left me stranded, my family stranded, or caused many other traveling issues throughout my driving experiences. I repaired this around two years ago, but have been terrified to drive my truck! I’ve driven about 1,000 miles or less since the repair (in 2 years time). I’m selling first chance I can, BUT, I WANT MY MONEY BACK! I have the receipt in a safe for when this becomes a recall - to prove i paid it, and to get a FULL REFUND!!! That is not how good business is done by Toyota. I owned a 2004 and 2005 Camrys prior, as well as a 2014 Lexus GS 350 F Sport (all in my name), this truck was a dream, now a nightmare. Please, for everyone complaining online and those that have had to also pay for these repairs @ low mileage, MAKE THIS INTO A RECALL FOR 2016 TACOMAs.

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.

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.

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.

WHILE DRIVING ON THE FREEWAY, THE VEHICLE STARTED LURCHING AND LOOSING POWER THEN ABRUPTLY SHUT OFF.

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.

HESITATION UPON ACCELERATION AT TIMES.

AS OF NOW THE AC FAN MAKES A LOUD NOISE LIKE SOMETHING FELL APART. THERE IS NO AIR BLOWING THROUGH THE VENTS. IT SOUNDS LIKE BROKEN BLOWER MOTER.

WHEN MY A/C STOPPED WORKING DURING THE WARRANTY PERIOD, I HAD IT CHECKED AT GLENS FALLS TOYOTA WHERE I WAS TOLD THE CONDENSOR NEEDED REPLACEMENT. THEY DETERMINED THAT THE HOLE HAD BEEN CAUSED BY A ROCK KICKED UP BY THE VEHICLE AND THAT IT WOULD NOT BE COVERED UNDER WARRANTY. I AM CONCERNED ABOUT THIS POLICY, AS THERE ARE MANY OTHER ENGINE COMPONENTS THAT - LIKE THE A/C CONDENSOR - ARE NOT SHIELDED ON THIS OFF-ROAD CAPABLE VEHICLE. MY VEHICLE HAS NEVER BEEN DRIVEN OFF-ROAD.

BROUGHT VEHICLE IN TO DEALERSHIP( NORTHWAY TOYOTA) FOR RECALL NOTICE, AND VEHICLE STALLING. THEY SUPPOSEDLY REPAIRED IT, BUT VEHICLE IS DOING THE EXACT SAME THING, STALLING AND MALFUNCTION INDICATORS ARE ON. CONTACTED THE DEALERSHIP BUT NO ONE WILL RETURN MY CALL. I DON'T THINK THEY DID ANYTHING TO MY VEHICLE THE FIRST TIME.

CRANK POSITION SENSOR-TRUCK WAS IN MOTION ON A CITY STREET WHEN IT BUCKED AND STALLED. IT STARTED AGAIN AND I WAS ABLE TO MAKE IT A BLOCK TO MY MOM'S HOUSE/GARAGE, WHERE I KEEP MY TRUCK. AS I WAS PULLING INTO THE GARAGE, IT BUCKED AND STALLED AGAIN. I REPLACED THE CPS (CRANK POSITION SENSOR) BECAUSE I DIDN'T WANT MY TRUCK TOWED TO THE DEALERSHIP. IT COST ME $110 BUCK. I'M REALLY GLAD I WASN'T OUT CAMPING OR IN TRAFFIC WHEN THIS OCCURRED, AS IT COULD HAVE BEEN A MUCH WORSE SITUATION.
