2017 Toyota Tacoma Electrical Problems

Product identification: Brand: Dasaita Model: HA2161H3 ASIN: B0CQNWQR8D Purchased: September 4, 2025, via Amazon Aftermarket Android head unit installed in a 2017 Toyota Tacoma TRD Sport caused electrical interference with the vehicle's brake stop switch circuit (DTC C1425), resulting in autonomous braking without driver input, simultaneous ABS and Traction Control warning lights, and a dashboard warning indicating simultaneous accelerator and brake input. Two independent repair facilities confirmed the head unit as the probable cause. Symptoms resolved upon removal of the head unit and reinstallation of the factory OEM unit. The product is currently listed as unavailable on Amazon. Injury or accident: None, but describe it as a near-safety incident since the vehicle was braking itself while in motion.

Clock spring has failed. I've lost all steering wheel button controls as well as cruise control. Air bag light has now come on. I am afraid that if I get into a wreck, the airbag will not deploy. This seems to be a common issue with this select year for this Tacoma.

The high mount rear stop lamp leaks water into the cab. The water channels in through a cheap gasket, down the inside of the frame, destroying the cushions and plastic through moisture and mildew. Toyota Corporation and Precision Toyota of Tucson (service) AZ, both say the problem is only covered by the regular 36,000 mileage, 3 year warranty. They want to charge me $575 to replace the light. However, the known issue doesn't occur because of miles driven or even age of the vehicle. I live in the desert and it has not rained significantly since I bought the truck new in 2017, according to the National Weather Service. This year, with record rains, water is freely seeping in to the cab. Toyota should recall Tacomas with this issue and replace the cheap gasket it used to manufacture these trucks.

LEFT TURN SIGNAL QUIT WORKING WHILE DRIVING ON A CITY STREET MAKING A LEFT TURN. TOYOTA TOOK 4.5 HOURS TO DIAGNOSE THE PROBLEM. SAID IT WAS IN THE INSTRUMENT CLUSTER AFFECTING THE TURN SIGNAL AND ODOMETER. SAID IT WOULD TAKE A WEEK TO GET PART AND THEY NEEDED TO KNOW HOW MANY MILES I WOULD DRIVE IN THAT WEEK BECAUSE THE ODOMETER HAD TO BE SET TO EXISTING MILES PLUS THE MILES I DRIVE DURING THE WEEK. ONE WEEK LATER WAS TOLD THE PART WAS ON BACK ORDER AND IT WOULD BE 30 TO 60 DAYS FOR THE PART. I GOOGLED THE PROBLEM AND FOUND MANY COMPLAINTS OF "LEFT TURN SIGNAL GOING OUT" ON TOYOTA TACOMAS DATING AS FAR BACK AS 2012. OBVIOUSLY TOYOTA KNOWS OF THE PROBLEM. HAVE THEY FIXED THE PROBLEM ON THE REPLACEMENT PART OR IS IT PRON TO GO OUT AGAIN. HOW MANY PEOPLE HAVE HAD TO DRIVE FOR ONE OR TWO MONTHS WITHOUT A LEFT TURN SIGNAL, HOW MANY ACCIDENTS HAVE OCCURED BECAUSE OF NOT HAVING A LEFT TURN SIGNAL, HOW MANY CITATIONS HAVE BEEN ISSUED FOR FAILURE TO USE TURN SIGNAL. HOW MANY VEHICLES DO NOT HAVE THE CORRECT MILEAGE ON THE ODOMETER, MINE WONT UNLESS THEY CONTACT ME AND ASK HOW MANY MILES I HAVE DRIVEN PRIOR TO SHIPPING THE PART AS I WAS TOLD IT HAD TO BE SET AT THE FACTORY BEFORE SHIPPING. IN ADDITION THE DIAGNOSTIC COAST WAS $150.00 THE PART WILL BE $750.00 PLUS LABOR TO INSTALL. I FEED TOYOTA SHOULD HAVE KNOWN EXACTLY WHAT THE PROBLEM WAS WHEN TOLD THE LEFT TURN SIGNAL QUIT. I GOOGLED IT IN LESS THAT 5 MINUTES. SO FAR NO INVOICES TO SHARE.

OCCASIONALLY WHEN DRIVING THE SPEEDOMETER DOES NOT SHOW THE ACCURATE SPEED SUCH AS THE SPEEDOMETER SHOW 0 WHEN GOING 30MPH. THERE IS ALSO A WEIRD METAL CLANKING NOISE WHICH SOUNDS LIKE ITS COMING FROM THE TRANSMISSION AND SOUNDS LIKE ITS TRYING TO SHIFT GEAR WHILE IN REVERSE OR DRIVE. ALSO THE AIR CONDITIONING FAN MOTOR HAS CRACKED AND WHEN TURNED ON SOUNDS LIKE A MOTORCYCLE REVING IT'S ENGINE.

DRIVERS SIDE SEAT HEATER STOPPED WORKING. I RESEARCHED ONLINE AND FOUND THIS TO BE A COMMON ISSUE AND WAS PROBABLY DUE TO A BURNT UP CONNECTION AT SEAT HEATER AMP LOCATED UNDER THE DRIVER SEAT. I CONTACTED MY DEALER AND TOLD THEM THERE IS A VISIBLY BURNT CONNECTION BUT WAS ADVISED THAT SINCE I WAS 600 MILES PAST WARRANTY, THERE WAS NOTHING THEY COULD DO. I CALLED TOYOTA USA AND GOT A CASE NUMBER AND WAS AGAIN TOLD THERE WAS NOTHING THEY COULD DO.WITH ALL THE IMAGES OF BURNT CONNECTORS THIS SEEMS TO BE A FIRE HAZARD.

PURCHASED TRUCK JULY 24, 2017 FROM MARK MILLER TOYOTA IN SALT LAKE CITY, UTAH. IN THE FIRST 6 MONTHS I LOST BRAKES 3 TIMES. WENT TO DEALER EACH TIME. THEY COULDN'T DUPLICATE SO NO REPAIRS MADE. AFTER THE 3 TIMES A RECALL CAME OUT, 18V888. EXACT SYMPTOMS. THEN A FORTH TIME HAPPENED AND THEY SAID THE RECALL DOESN'T EFFECT MY VIN SO THEY STILL HAVE TO DUPLICATE. TODAY, FEBRUARY 27, 2019 TRUCK WOULDN'T STOP AND I RAN THRU A STOP SIGN, AND IT WAS CONT ON MY DASH CAM. WITH THIS PROBLEM MY SEATS ARE LOOSE AND SOMETIMES DON'T LOCK. WHEN EVER IN 4 WHEEL DRIVE THE SEAT BELTS LOCK UP AND WONT UNLOCK LOCK. I'VE HAD NOTHING BUT ISSUES WITH THIS TRUCK AND NOTHING WILL EVER GET FIXED AND I'M SCARED TO DRIVE MY VEHICLE ESPECIALLY WHEN MY DEALER WON'T REPAIR ANYTHING. ALSO BELIEVE IT HAS SOMETHING TO DO WITH THE VEHICLES OFF-ROAD OPTION, CRAWL CONTROL, WHICH USES ABS.

I HAVE A 2017 TOYOTA TACOMA WITH 53000 MILES ON IT. THE SQUIRREL CAGE ON THE AC BLOWER MOTOR BROKE TODAY DURING A 100 DEGREE DAY. FROM WHAT I CAN SEE ON LINE THERE IS A BACK ORDER ON THE REPLACEMENT PART. THE PLASTIC FEMALE PORT FOR THE SHAFT CRACKED IN HALF AND NOT THE CAGE MAKES A HORRENDOUS NOISE. POOR DESIGN: METAL SHAFT SPINNING INSIDE PLASTIC IS A RECIPE FOR A STRESS CRACK WHICH IS WHAT THIS APPEARS TO BE. MY TRUCK IS OUT OF WARRANTY SO NOW I AM STUCK PAYING FOR THE REPAIR!!

THE SPEEDOMETER WOULD GET STUCK AND NOT DISPLAY AN INCREASE OR DECREASE IN SPEED WHILE DRIVING. OR IT WOULD DISPLAY AN INCREASE IN SPEED UP TO 60 MPH AND THEN TREAT 60 AS 0. EX. I WAS GOING 45 BUT IT READ THAT I WAS GOING 95. OR SOMETIMES, IT WOULD JUST INCREASE ALL THE WAY TO 120 MPH AND THEN STOP. TURNING THE VEHICLE OFF AND THEN BACK ON DID NOT MAKE A DIFFERENCE. THE GAUGE WOULD STILL READ WHERE IT WAS WHEN THE CAR WAS TURNED OFF. I WAS NEVER SURE OF THE SPEED I WAS GOING AND BROUGHT THE VEHICLE INTO THE DEALER WITHIN A MONTH OF THE OCCURRENCE. THE TRUCK WAS ONLY 10 MONTHS OLD. THE VEHICLE HAS BEEN AT THE DEALERSHIP FOR 2 MONTHS. THEY ARE WAITING ON TOYOTA TO CREATE & SHIP A NEW SPEEDOMETER BECAUSE TOYOTA IDENTIFIED THAT THE SPEEDOMETERS IN SOME OF THEIR MAKE/MODELS WERE FAULTY.
