2017 Toyota Tacoma engine problems

ENGINE

Truck has 116k miles, started losing power and acceleration diminished. CEL and Trac Off light came on. Pulled over twice after experiencing same issue. Took to mechanic and diagnostic code P0301 (cylinder 1 misfire). Replaced 6 spark plugs to be safe, and replaced broken coil in cylinder 1. Drove less than a mile and CEL came back on. Brought to dealership this time and they found a leak in the head gasket and noticed warping in cylinder 1, along with code P0301 still present. They reported back to me stating it needed a machinist to resurface the the cylinder head, that the repair is mechanical. Even outside of warranty this fix should not be costing $13,000. The truck has been properly maintained for the past 9 years, all oil services and replacing any wear and tear items. Mechanical (warping) is manufacturing issues.

ENGINE

I was driving on the highway when my vehicle suddenly lost power. The engine light and traction control light came on, and I lost power, and the engine started sputtering. I had to pull off to the side and put on hazards. My Tacoma would only drive about 25 MPH after this happened. Based on a quick search, this is a very common problem in 3rd-generation Tacomas!

ENGINE

2017 Toyota Tacoma double cab-V6 with 62K approx miles. On or around April 29th 2024, I was traveling in this truck when there was a sudden and complete loss of power, two check engine lights came on-The "trac off" light and the check engine light came on. I needed to pull over immediately for safety. I ended up driving the vehicle to the Toyota dealership in limp mode. The vehicle has sat at Tustin Toyota now for weeks with the Toyota dealership initially suggesting that a ACIS Flap broke off inside the intake manifold of the car. This was replaced and the vehicle is still providing the same alarms and still in limp mode. The initial fix(whihc did not fix the problem was a full replacement of the intake manifold). Now the dealer is suggesting that a piece(s) broke off the intake manifold and ended up inside the engine so now dealer is recommending and entire engine break down to attempt to further diagnose the situation. Again it looks to be a complete failuure of the ACIS system and the intake manifold. This problem has presented a EXTREME safety issue due to comp[lete loss for power initially then truck sits in LIMP Mode. Very dangerous!

It has been well established among 2016 and up Toyota Tacoma owners and clubs that the Rear Coolant Bypass Joint leaks at different mileages, If the loss of coolant happens rapidly enough the engine could overheat and siez up and cause the pistions to weld to the cylinders along with causing extensive engine damage not to mention how the driver would handel the truck, Toyota dealerships and Manufacture also know of This Coolant Bypass joint leak and how common it is. Also the corrosive build up from the antifreeze will cause other parts and wires to not work, Attached is my part and the build up of antifreez before the leak,

HEARD VALVES TAPPING ALOT OF TIME. REPORTED AND TOOK TO TOYOTA. THEY SAID NO CODE NO WORK. THEY GAVE THE LINE OF WHEN THIS GAS HITS THIS PART THEN THIS ONE TRIES TO CATCH UP OR BURN EXCESS FUEL. OUT OF 40 PLUS YEARS AND PUCHASING MANY VEHICLE I NEVER BEEN TOLD THAT BEFORE. I TALKED TO OTHER 2017 OWNERS AND THEY DONT HAVE THIS ISSUE. ALSO THE BRAKES MAKE METALIC CLUNKING NOISES MOVING BACKWARS AND FOWRDS WHEN BRAKING. THIER ANSWER WAS FLOATING VALVES. AND AGAIN THIS ISSUE ISNT ON OTHER TACOMMA OWNERS.

NOTICING THAT AS I COME TO A STOP AT THE LAST SECOND THE DRIVETRAIN SEEMS TO SNAP OUT OF GEAR CAUSING A VERY LOUD CLUNK AT THIS POINT THE VEHICLE SEEMS TO FREE WHEEL FORWARD UNSAFELY. . THE JOLT YOU GET CAN BE COMPARED TO PUTTING THE VEHICLE INTO GEAR AT TOO HIGH OF AN IDOL, WHICH WILL CAUSE PREMATURE WEAR AND TEAR TO YOUR DRIVETRAIN. ALSO, THE ENGINE SEEMS TO SURGE AT IDOL WHILE IN GEAR AND IF YOU AREN'T READY FOR IT AND YOU ARE PARKING BEHIND SOMETHING, YOU RUN THE RISK OF HITTING IT.. I HAVE ADDRESSED THE DRIVETRAIN ISSUE WITH THE DEALER, BUT THEY SAY THEY CAN'T GET THIS TO HAPPEN FOR THEM. VERY INTERESTING CONSIDERING THERE SEEMS TO BE OTHERS WITH SIMILAR ISSUES.

ENGINE STALLS WHEN ATTEMPTING RAPID ACCELERATION WHEN ENGINE RPM IS LESS THAN 3000. THIS IS A SAFETY ISSUE. I RECENTLY ATTEMPTED RAPID ACCELERATION WHEN MAKING A LEFT TURN TO AVOID A COLLISION WHERE AN ONCOMING DRIVER RAN A RED LIGHT. THE ENGINE STALLED. I HAVE EXPERIENCED OTHER SIMILAR INCIDENTS. I HAVE REPORTED THIS TO MY TOYOTA SERVICE CENTER TWICE. THE FIRST TIME I WAS TOLD TOYOTA IS AWARE OF THE CONDITION, WHICH WOULD BE ADDRESSED IN A SOFTWARE UPDATE. THE SECOND TIME I WAS TOLD MY ENGINE WAS OPERATING WITHIN NORMAL SPECIFICATION PARAMETERS, AND NO SUCH SOFTWARE UPDATE WAS FORTHCOMING. IT WAS RAINING THE DAY I BOUGHT THIS VEHICLE, SO IT WAS NOT POSSIBLE TO TEST LOW END ACCELERATION. I WOULD NEVER HAVE BOUGHT THIS VEHICLE HAD I KNOWN LOW END ACCELERATION WAS SO LETHARGIC. ON SEVERAL OCCASIONS IT HAS NEARLY GOTTEN ME KILLED.

I BOUGHT A TOYOTA TACOMA THINKING I WAS PURCHASING A ROUGH TUFF TRUCK. IT IS BY FAR THE WEAKEST TRUCK/CAR I HAVE EVER DRIVEN. IT HAS NO POWER, CANNOT PULL MORE THAN AN INFLATABLE RAFT, DOWN SHIFTS IF A BUTTERFLY FLIES IN FRONT OF THE TRUCK. GAS MILEAGE IS PATHETIC, MY KIDS 2004 FORD RANGER HAS TWICE THE POWER AND CAN CARRY AND TOW THREE TIMES AS MUCH AS THE TOYOTA. THE TRUCK IS PATHETIC! SHAME ON YOU FOR SELLING ME SUCH A WEAK SHAMEFUL TRUCK.
