2017 Toyota Tundra Complaint Log

The factory IBC is a safety issue. I would not tow anything over 1500lbs as the brake controller does not work. This controller is an accident waiting to happen. When set on gain 10 you can barely feel a tug from the trailer. You can't feel anything if you apply the vehicle brake pedal. On a gain of 10 it should lock up the trailer brakes, and it can't do that on a dirt road much less on asphalt. Toyota has not done anything to fix this issue AT ALL! Lots of truck owners out there that don't even know of this problem and alot of owners are forced to install aftermarket brake controllers on their dimensions. Toyota should be held to fixing this safety issue. Why isn't there a recall on these vehicles. It's a problem that multiple year tundras! I purchased this vehicle to tow a 16' travel trailer weighin3500 lbs. I tried to adjust the controller in the neighborhood and was not happy or safe with the test. I will not tow with the factory setup. UNSAFE!

Began experiencing long cranking, difficulty starting, then rough idling. Started researching online and found recalls for 2018 -2019 Flex fuel 5.7 Tundras. My 2017 is also a Flex fuel 5.7 with exactly the same issue. Dealer says 2017 not covered. I had to pay over $2000 to have the fuel pump replaced, ECM reprogrammed. I don’t understand why 2017 was not included in the recall. Please NHTSA consider extending this recall to 2017. I am reading numerous complaints on this website about the same issue from owners of 2017 Flex fuel Tundras.

The transmission solenoid D shows high voltage which sets my check engine light off. At first no difference would be noticed and it would randomly turn off and then back on randomly. After doing this on and off for the last few months, the transmission has randomly been getting stuck in 4th gear but will lower when slowing down. According to those who have had the same issue have found it to be fixed by replacing the S4 solenoid which seems to be producing way more voltage than it’s supposed to

Cold starting problems so the dealer diagnosed as a defective fuel pump.

Power steering rack and pinion failure on 2017 Toyota Tundra Limited. Leak and Popping clunk noise when turning steering wheel . Potential for steering loss and accident.

The contact owns a 2017 Toyota Tundra. The contact stated while driving 65-70 MPH, the TPMS warning light illuminated. The contact pulled over and became aware that the passenger's side rear tire was losing air. The contact attempted to use the OEM jack; however, the jack was too small. The contact used several rocks to add height to raise the vehicle up with the OEM jack. The flat tire was replaced with the spare. The contact was concerned about the vehicle falling off the jack. The vehicle was taken to the local dealer, and the tire was patched. The vehicle was repaired. The dealer declined to replace the jack. The manufacturer was contacted and opened a case. The failure mileage was approximately 87,500.

My 2017 Toyota Tundra had been starting roughly the past couple of weeks, I initially thought this was due to the very cold weather we recently had. It has just over 71k miles on it, so there should be no issues with this truck. Then on the afternoon of 1/16/25 I tried to start my truck and it would turn over, but not start. No fuel was getting to the engine. I did some research on this issue and it seems a recall was issued for 1.5 MILLION Tundras from 2017. I did a search for my VIN and nothing comes up. I want this fixed by Toyota as it should be included in the recall. Now I have a useless hunk of metal sitting at my house because I cant even start it to get it TO the dealership. Please help me resolve this and have Toyota take care of the problem. I dont understand why my vehicle was not included in the 1.5 million vehicles initially covered. Please, help consumers out with this. Please advise. Thank you in advance.

Headlights go out randomly usually when using turn signal. Because this happens at night all visibility is lost temporarily. This also confuses other drivers. I haven’t taken the vehicle to the dealer because the symptom is very sporadic and difficult to duplicate. Dealerships will not fix anything unless they can witness the issue. No warning lights or messages were displayed. This problem has been documented numerous times by many different owners on Toyota Tundra forums.

Diagnostic report indicates problem with shift solenoid and it’s replaceable. Dealership instead charge me for full transmission replacement.

Flex Fuel Extended Crank when engine is cold. Have had into dealer multiple times and fix is temporary. Known issue with flex fuel Tundras that keeps returning

My 2017 Toyota Tundra Limited has 107,192 miles. I took the vehicle to Berlin City Toyota in Portland, ME for an oil change. The service technician told me that the truck has a cam tower leak. The engine is leaking oil directly onto the exhaust manifold. The service technician told me that if the leak gets worse the engine oil could combust and the engine would light on fire. I regularly have my truck serviced at Berlin City Toyota in Portland, ME, which is where I purchased the truck. I have documented with Toyota that the truck has been burning or leaking oil since it purchased the truck when it had 43,000 miles. No leak was ever found by Toyota until yesterday. The cost to repair this issue is $5600. No warning lamps or messages have ever appeared on the truck. Toyota says this is a common issues with the 5.7 liter V8 engine in the 2017 Tundra. I feel that it should be covered by warranty or a recall should be put in place for the cam tower leak on the Toyota Tundra being that the engine could light on fire with no warning due to the faulty seal on the engine.

The contact owns a 2017 Toyota Tundra. The contact stated that after attempting to start the vehicle, the engine failed to turn over. The contact stated that after several attempts, the vehicle started. The vehicle was taken to the dealer where it was diagnosed and determined that the fuel pump and the CPU had failed, and the fuel pump needed to be replaced, and the CPU needed to be reprogrammed. The vehicle was repaired; however, the failure recurred. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The contact was able to restart the vehicle. The check engine warning light illuminated. The contact stated that he used a code reader to diagnose the vehicle and the result showed that an ethanol fuel type had been detected instead of regular fuel to refuel the vehicle. The contact stated that the system was confused, and that ethanol was not the fuel type that was used. The dealer was not notified of the failure. The manufacturer was notified of the failure and the contact was informed that the VIN was not included in a recall. The failure mileage was approximately 78,000. The VIN was unavailable.

The contact owns a 2017 Toyota Tundra. The contact stated that while starting the vehicle, while the vehicle was idling in park, the driver’s and passenger’s side curtain air bags deployed. The contact took the vehicle to the dealer who was unable to find the cause of the failure. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case regarding the failure. The approximate failure mileage was 90,000.

The horn stopped working. I noticed this in an emergency situation. The horn which is a safety feature should not fail especially for a relatively newer vehicle with less than seventy thousand miles.

Our 2017 Toyota Tundra has been having difficulty starting, takes multiple attempts before starting. We brought it to Toyota dealership and had a diagnostic done. They told us we need new fuel pump and the ECM software needs to be updated. There is a know problem with Denso fuel pump system along with class action lawsuit. We were told that our vehicle is not included in that lawsuit. We were also told by Toyota dealership that the fuel pump is on back order and they are not sure when it will arrive. They said it could take months. With this fuel pump issue our safety is at risk because our vehicle could lose power at any time. There were no warning lights to alert us to this issue.

My airbag sensor is active. My vehicle only has 94000 miles on it. Power training warranty does not cover this failure. This happened when my car was parked and I turned on the engine and the sensor remains active.

https://static.nhtsa.gov/odi/tsbs/2019/MC-10170730-9999.pdf It is this issue. I just bought my truck at 83000 miles and toyota would not fix it since it is 3000 miles over the emission warranty.

Vehicle was driven 30 miles to work with no steering issues and parked in work parking lot. Upon returning to vehicle to return home when backing out of parking spot the front driver wheel would not turn almost causing me to back into parked car next to me. I looked under the front of the driver side tire, and noticed the outer tie rod was hanging down, and was causing the no steering issue. I called a tow truck, and had the vehicle taken to the Toyota dealer where vehicle was purchased new. I informed the dealer to be careful with the vehicle as the outer tie rod on driver side was broken and was not possible to drive. The Toyota dealer investigated the issue and found that the threads on bother inner and outer tie rods on both passenger and driver side was stripped. All outer and inner tie rods on the vehicle had to be replaced due to the threads being stripped on all 4 tie rods. My concern is this truck only has 86,000 miles on it, and if I had been travelling on interstate at 70MPH and the tie rod broke it would have resulted in a catastrophic collision due to a no steering condition. This vehicle has never sustained any front end damage of any type. I can provide the dealers name and the notes on the repair bill from the Toyota dealership stating exactly what I have stated in this report.

Intermittent failure of the integrated trailer brake controller system. System indicates a frequent intermittent fault indicating a wiring or connection issue that disables the signal to activate the trailer brakes resulting in no trailer braking. Vehicle and trailer are available for inspection. I was travelling down a 6% grade mountain (Arizona SR87 MP224) an exhibited a loss of trailer brakes. Taking the trailer to the dealer on flat level service experienced intermittent loss of trailer brakes. Toyota Integrated Brake Controller (IBC) intermittently and randomly indicating a fault in the trailer wiring. •Rapid clicking of the IBC’s electrical relays. •In fault mode, the IBC disables the trailer brakes. •Sometimes the IBC works perfectly for miles and then goes into fault mode for an unknown reason. •Sometimes, the IBC goes into fault mode just plugging the trailer into the electrical socket without even taking the truck out of drive or depressing the brake pedal. •All external trailer lights include turn signals are functioning normally. Examination and diagnosis to date: •Toyota IBC was removed and replaced with a Tekonsha P3 brake controller using a Tekonsha wiring harness adapter to plug directly into the Tundra’s wiring harness used by the original Toyota IBC. The P3 is giving the error as brake circuit short-circuit, overload. •The travel trailer is a 2022 Jayco 212QBW, dual axle. •I brought the trailer to the dealer I purchased it from to have the brake system checked for faults. I’ve attached a copy of receipt from the dealer service department. In short, they examined the following and concluded the issue was with the Tundra. - The trailer wiring was physically examined with no deficiencies. - Trailer connected to the dealer's Chevy Silverado and driven around town with no faults. Toyota dealership claims they can find no fault with their tester. They would not use my 7-pin tester that also exhibits the same problems.

We were recently advised our 2017 Tundra needs a new fuel pump because it is not getting enough compression. We were told the 2018 Toyota Tundra and many other vehicles made by Toyota have been recalled for this exact same issue we are having but there have not been enough complaints about the 2017. Well here’s a complaint. I have to pay for a fuel pump known to be bad by Toyota but since enough people haven’t complained about a problem they are aware of isn’t fair. Please put my complaint in so something might be done about this.

Fuel Pump failed. Vehicle is currently at dealership awaiting 2+ week repair. Currently available to inspect. Failure began while driving. Caused misfire in cylinder 1, caused electrical fault that disabled traction control. Potential to leave the vehicle inoperable on the roadside poses a safety risk. Toyota dealership in possession states "START WITH FUEL PUMP, REPORGRAM ECM PER TSB AND RELEARN FUEL DENSITY FOR ALCOHOL CONTENT FLEX FUEL VEHICLE, OUT OF WARRANTY FOR TSB" Toyota dealership is the only entity to perform any inspection. There were no warning lamps or messages related to the fuel system. Check engine light and message stating "Traction Control Off" appeared while driving the vehicle. After limping the vehicle home, the vehicle would not start.

As I am driving down the pickup loses power/ has no power. Was driving down the interstate and trying to make it up the Harbor bridge I could only go 40. Then try to pass a semi that (BAD DRIVER) was dangerously close, I could not even pass him. Not to mention people were angry at me and getting defensive. There were no warning lights, I took it in immediately. It has been inspected by my secondary warranty I purchased. ( Tripple Diamond 1-833-909-0015 or 1-844-526-0415 our policy # is [XXX] under [XXX] -So I take it to the Toyota Dealership in Corpus Christi Texas, They then tell me it is my Secondary air pump (both Sides) and Valves including Gasket, Air Tube, Pump Assembly, air, (2 both sides)/inlet, Air pump(1) and valve set, emission (1) That was on 12-16-2022 (it has been there since) this will cost me $3,205.38 out of pocket. But the real problem is that there is a long waiting list of people waiting for this same part, so no one can get it. Many people with the same problem last I called I was 44 people in line. I only have 75,000 miles on my truck, and still have the same tires That are in great shape (I rotate them) So for this to happen seems strange, I take special care of this truck.

When driving at night, the front lights of the vehicle turn off randomly. Been driving on an highway at going at 75mph and randomly the headlights shuts off. Happened 4 times in the past year.

The contact's son owns a 2017 Toyota Tundra. The contact received notification of NHTSA Campaign Number: 21E103000 (Steering) however, the part to do the recall repair was not yet available. An unknown local dealer was contacted and informed the contact's son that the remedy for repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact's son had not experienced a failure. VIN tool showed no Unrepaired recalls associated with the VIN.

NHTSA Recall No. 21E-103 I received a recall letter for my vehicle about a potentially defective power steering gear service and I called my local dealer about it and they said only if you put one in since August 5 2021 I said no but I think I have a steering problem sometimes while driving and they could look at my vehicle just to make sure it is ok. They said since it is no in this time frame that if you brought it in that I will have to pay for the inspection and will cost $150 dollars. I GET A LETTER ABOUT MY VEHICLE FOR A RECALL AND THEY WANT ME TO PAY FOR IT EVEN IF IT WASN'T IN THIS TIMEFRAME BUT I CAN BE DRIVING AND MAYBE GET KILLED IF I HAVE BAD STEERING GEAR!!!!!!!!

I believe my Tundra has an emissions problem that Toyota will not cover. The FUEL TANK ROLL OVER VALVE is stuck. I believe this is a hazards condition. Toyota say the fuel tank will have to be replaced and not under warranty. Truck was purchased new by me and has 38887 miles.

Headlights, taillights and all dash and interior lights go out when using turn signal at night. My and others safety has been put at risk due to the loss of headlights and taillights when engaging the turn signal. Those in my truck as well as those in surrounding vehicles are at risk because of the lack of exterior illumination while driving. Toyota dealer has not been able to reproduce the problem as the technicians do not work at night to drive the truck in the dark when headlights would be in use. Vehicle has not been inspected by any third parties just the dealership. There were no waring or messages or other symptoms of the problem before the failure. Problem first appeared in January 2022 and has occurred on over 6 occasions before truck was taken to dealership in February 2022. Truck was taken to dealership after lights went out at 70 MHP when signaling to exit highway at night.

Integrated Brake Controller (IBC) not sending sufficient power to electric dual-axle travel trailer brakes producing weak if any braking ability. On the approach to the first red traffic signal, there was zero braking from the trailer requiring full braking from the tow vehicle risking a crash. The IBC is providing no warning or failure indicators to the user. The vehicle and IBC are available for government inspection. The travel trailer in use is a 2022 Jayco Jay Flight SLX8 212QBW. While towing a 5,000 pound dual-axle travel trailer for the first time since I purchased the truck brand new from Toyota in 2017, I attempted to setup the IBC. Instructions say to set Type, which I set to electric brakes matching the trailer, then adjust the gain up while travelling around 25 miles per hours. When lock up of the trailer brakes occur, reduce the gain slightly to prevent full lock up. At a Gain of 10 (10 is the maximum), I could not achieve brake lock up and could only obtain weak trailer braking. The trailer was tested with a different tow vehicle and there were no problems obtaining lock up at mid-range gain. I had Toyota inspect the software updates to the IBC on January 14, 2022 and Toyota advised the IBC is up to date on its software and functioning correctly. The Tundra is out of factory warranty, but since I did not own a travel trailer during the warranty period, there was no way for me to test the IBC before going out of warranty.

I purchased a CPO 2017 Tundra SR5 Double Cab. Within a month of ownership, the EVAP system failed due to a faulty charcoal canister. Truck didn't even have 60,000 miles on it. This was covered under warranty, but the local Toyota Dealer, tried to make me pay for it anyway.

Right headlight leveling motor failed causing headlight to point at the ground. I now have limited night time visibility on a 13,000 mi. vehicle. Toyota does not offer a replacement part nor do aftermarket sellers. A Youtube video of one of these dismantled motors shows a cheapest of the cheap device. Auto manufacturers should not be allowed to use cheaply made items to point headlights! Dealer refused warranty and wants $500+ for a new headlight that will last 13,000 mi. When the left side fails, I will no longer be able to drive at night. This is beyond absurd that a manufacturer is allowed to use the cheapest parts possible on a safety device such as a headlight.

THE HEADLIGHTS AND THE INTERIOR LIGHTS TURN OFF WHEN I USE THE TURN SIGNALS. THIS HAS HAPPENED SEVERAL TIMES SINCE I HAD THE TRUCK, THE LAST TIME THIS HAPPENED THE LIGHTS WERE OFF FOR ABOUT 5 MINUTES. THE TRUCK IS BEING LOOKED AT BY THE DEALERSHIP BUT THEY CAN'T RECREATE THE ISSUE. THIS IS A SAFETY PROBLEM

MY TRUCK WON'T START AND THE SYMPTOMS DIRECTLY MATCH THE RECALL ALREADY IN PLACE FOR THE FOLLOWING YEAR. VEHICLE EVENTUALLY STARTED BUT SPEWED OUT ALLOT OF UNBURNED FUEL OUT OF EXHAUST PIPE.

TRAILER BRAKE CONTROLLER DOES NOT WORK AND IT ALMOST CAUSED A CRASH. NOW IT DOES NOT EVEN SHOWS UP ON DISPLAY AS IF TRUCK IS NOT EVEN EQUIPPED WITH THIS MODULE. EXTREMELY SCARY AND DANGEROUS WHEN TOWING 6000IB BEHIND YOU AND YOUR TRAILER BRAKES FAIL TO ENGAGE. INTERNET IS BUSSING WITH TUNDRA OWNERS WITH SAME ISSUE.

WHILE DRIVING AT NIGHT AND THE LIGHTS ARE ON AUTO, PRESSING DOWN FOR THE LEFT SIGNAL THE HEADLIGHTS GO OUT AND THE DASH BECOMES DIM AS IF I AM DRIVING DURING THE DAY WHICH IM NOT. THE VEHICLE IS MOVING WHEN THE LIGHTS GO OUT . PLEASE FIND A RESOLUTION BECAUSE THIS IS DANGEROUS AND COULD CAUSE OTHERS TO COLLIDE WITH ME WHILE ON THE ROAD.

MY 2017 TOYOTA TUNDRA 1794 CREWMAX, DURING WINTER MONTHS IN SOUTH CAROLINA - THE HEADLIGHTS, TAIL LIGHTS AND INTERNAL INSTRUMENTATION WILL TURN OFF WHEN TURNING LEFT OR RIGHT WITH TURN SIGNAL ENGAGED. THIS ONLY HAPPENS WITH THE LIGHTS IN THE AUTO POSITION AND NOT IN THE MANUAL POSITION AND THE ISSUE OCCURS AT NIGHT INTERMITTENTLY WHILE THE VEHICLE IS IN MOTION!! SOMETIMES THE LIGHTS JUST FLICKER AND SOMETIMES THEY GO OFF AND STAY OFF. I HAVE ALMOST RAN OFF THE ROAD TWICE WHEN THIS HAS HAPPENED. IT HAPPENS MORE FREQUENTLY WITH COOLER TEMPERATURES. I HAVE HAD THIS ISSUE FOR OVER A YEAR NOW TRYING TO GET TOYOTA TO FIX IT. THIS IS A KNOWN ISSUE THAT TOYOTA DOESNT WANT TO FIX UNLESS THEY CAN DUPLICATE THIS ISSUE IN THE SHOP, IN WHICH THEY USUALLY CANT. THERE ARE MANY PEOPLE ONLINE COMPLAINING OF THE SAME ISSUE, ON FORUMS. THIS IS A SAFTEY ISSUE THAT NEEDS TO BE FIXED ASAP.

AUTOMATIC HEADLIGHTS SHUT OFF WHEN TURN SIGNAL IS USED. IT HAPPENS INTERMITTENTLY, BUT FREQUENTLY. I HAVE HAD THIS HAPPEN MULTIPLE TIME AT SPEEDS RANGING FROM 10 MPH TO 80 MPH BUT IT ONLY SEEMS TO HAPPEN WHEN THE AUTOMATIC HEADLIGHTS ARE ON AND THE TURN SIGNAL IS ACTIVATED.

WHEN ENABLING THE REAR DEFROSTER (AND SIDE MIRROR DEFROST), I HEARD A LOUD POP, AND NOTICED SMOKE UNDER THE PASSENGER WINDSHIELD WIPER. THE WINDSHIELD HAD CRACKED (PRESUMABLY FROM THE HEAT DIFFERENTIAL), AND THE WIPER STARTED TO MELT ON THE WINDSCREEN. THERE APPEARS TO BE AN ELECTRICAL SHORT DIRECTLY UNDER THE WINDSHIELD (AND UNDER THE PASSENGER WIPER) THAT IS RELATED TO THE DEFROSTER. THIS OCCURRED WHEN THE VEHICLE WAS STATIONARY, AND COLD (MORNING STARTUP).

THIS HAPPENED 4 TIMES TODAY THE VEHICLE WOULD STAY AT 1000 RPM WHILE DRIVING WITH NO ACCELERATION POSSIBLE, IT WAS AS IF THE GAS PEDAL WAS DISCONNECTED, TRIED TO CROSS BUSY INTERSECTION , BUT COULD ONLY COAST THREW. ALSO NO WARNING CODES AVAILABLE. LATER THE VEHICLE WOULD NOT SHIFT OR ACCELERATE IT WAS GOING 40 MPH AT 2000 RPM . THE TRUCK HAS 34500 MILES ON IT. TOYOTA SAYS NO ISSUES OF THIS KIND REPORTED AND I'M ONE MONTH OUT OF WARRANTY. I FEEL THIS IS VERY DANGEROUS, TRYING TO CROSS BUSY INTERSECTION , WHEN YOU CAN NOT ACCELERATE I'M GONNA GET KILLED.

TL* THE CONTACT OWNS A 2017 TOYOTA TUNDRA. THE CONTACT STATED WHILE DRIVING 35 MPH, WHEN HE NOTICED THE FRONT DRIVER'S SIDE TURN SIGNAL WAS INOPERABLE. THE CONTACT STATED THAT THE LIGHT BULB WAS MELTED. THE VEHICLE WAS TAKEN TO LOCAL DEALER TOYOTA ON NICHOLASVILLE LOCATED AT 2100 LEXINGTON RD, NICHOLASVILLE, KY 40356, (859) 887-4200, WHERE IT WAS DIAGNOSED WITH NEEDING FRONT PASSENGER'S SIDE TURN SIGNAL ASSEMBLY TO BE REPLACED. THE VEHICLE HAD BEEN REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS 65,508.

WHEN OPERATING THE VEHICLE WITH THE HEADLIGHT STALK/SELECTOR ON "AUTO", THE DASH LIGHTS AND HEADLIGHTS SUDDENLY GO TOTALLY BLACK OR OUT. I'M ABLE TO TURN THE LIGHTS BACK ON BY MOVING THE SELECTOR TO "ON". THE PROBLEM IS IT HAPPENS AND SOMETIMES YOU DON'T KNOW ALL OF YOUR LIGHTS ARE OFF WHEN DRIVING, ESPECIALLY IN THE CITY WITH OTHER BRIGHT LIGHTS. THIS CAN BE VERY DANGEROUS. THIS HAS HAPPENED SEVERAL TIMES, SO I NO LONGER USE THE AUTO FUNCTION ON MY STALK...TOO DANGEROUS. *TR

I HAVE A 2017 TUNDRA AND WHEN I USE MY TURN SIGNAL IT MAKES MY HEADLIGHTS AND MY DASH LIGHTS GO OFF. I HAVE RESEARCHED THIS ON THE INTERNET AND FOUND A STREAM THAT THIS IS A PROBLEM WITH A LOT OF THESE TUNDRA'S ARE HAVING THIS ISSUE. MY LIGHTS HAVE GONE OUT WHEN DRIVING AT NIGHT AND THIS IS A SAFETY HAZARD. I HAVE INCLUDE A LINK TO A BLOG OF A TON OF OTHER OWNERS THAT ARE HAVING THE SAME ISSUE. THIS NEEDS TO BE LOOK INTO BEFORE SOMEONE IS KILLED. HTTPS://WWW.TUNDRAS.COM/THREADS/AUTO-HEADLIGHTS-SHUT-OFF-WITH-TURN-SIGNAL.22968/

DRIVING AT NIGHT WITH HEADLIGHTS ON IN AUTO POSITION ALL LIGHTS SHUT OFF AS IF THE SWITCH WAS TURNED TO OFF. THIS HAPPENS USUALLY WHEN TURNING. A TAP ON THE TURN SIGNAL STALK / HEADLIGHT SWITCH BRINGS THEM BACK. IMPOSSIBLE TO RECREATE. THIS IS VERY DANGEROUS. THIS HAPPENS MONTHLY.

FUEL TANK IS SUPPOSE TO BE 37 GALLON. I HAVE NEVER PUT MORE THAN 28.5 GALLONS IN THE TANK. EVEN WHEN I RUN THE TANK TO THE RED LIGHT OR MY MILEAGE INDICATOR SHOW 20 OR LESS MILES REMAINING. I HAVE ASK THE DEALERSHIP TWICE ABOUT THIS AND THEY CLAIM IS A SAFETY FEATURE SO YOU DON'T RUN OUT OF FUEL. I RUN THE TANK DOWN TO 10 MILES LEFT IN TANK AND THAT IS WHEN I PUT 28.5 GALLONS INTO IT.

HEADLIGHTS FLASH OR TURN OFF WHEN USING THE TURN SIGNALS. DASH LIGHTS ALSO DIM. SEEMS TO HAPPEN WHEN I USE THE LEFT TURN SIGNAL. HAS HAPPENED SEVERAL TIMES. IF I TURN THE SWITCH TO THE OFF POSITION THEN BACK THEY HAVE TURNED BACK ON.

WHEN THE SIGNAL STALK IS PLACED ON AUTO AND IT IS CLEARLY DARK OUTSIDE THE HEADLIGHTS WILL INTERMITTENTLY TURN OFF WHEN PUTTING THE LEFT TURN SIGNAL INTO PLACE. THE LIGHTS WILL COME BACK ON WHEN THE SIGNAL STALK IS BACK IN THE NEUTRAL POSITION. THIS HAS HAPPENED WHILE IN MOTION, STATIONARY, AND AT DIFFERENT OUTSIDE TEMPERATURES. HOWEVER, I HAVE NOTICED THIS OCCURS MORE WHEN THE TEMPERATURE IS IN THE 40'S.

WHEN DRIVING AROUND AT NIGHT AND USE THE TURN SIGNAL, THE HEADLIGHTS WILL SHUT OFF AND INTERIOR DASH LIGHTS AND RADIO LIGHTS WILL DIM, AS IF IT IS DAY TIME. IT TYPICALLY HAPPENS IN THE MORNINGS WHEN IT'S COLD OUT.

CONNECTING IPHONE 11 PRO VIA BLUETOOTH CONNECTION TO RADIO CAUSES THE RADIO TO COMPLETELY REBOOT REPEATEDLY AND NO LONGER WORKS CORRECTLY. DETACHING THE BLUETOOTH IPHONE RETURNS THE RADIO TO NORMAL FUNCTION.

TL* THE CONTACT OWNS A 2017 TOYOTA TUNDRA. AFTER THE CONTACT PARKED THE VEHICLE, THE ODOR OF FUEL WAS PRESENT. THE FOLLOWING DAY, THE CONTACT DISCOVERED FUEL LEAKING FROM THE VEHICLE. THE VEHICLE WAS TAKEN TO WALKER TOYOTA (8457 SPRINGBORO PIKE, MIAMISBURG, OH) WHERE IT WAS DIAGNOSED THAT THE FUEL HOSE HAD BEEN DAMAGED BY RODENTS. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 24,000.

WITH THE HEADLIGHT SWITCH SELECTED TO 'AUTO' AND WHEN ENGAGING THE TURN SIGNAL TO THE LEFT DURNING NIGHT DRIVING, ALL EXTERIOR AND INTERIOR LIGHTS WOULD GO BLACK UNTIL TURN SIGNAL SWITCH IS MOVED TO THE ON THE POSITION. VEHICLE WAS TAKEN LOCAL TOYOTA DEALERSHIP SERVICE DEPARTMENT TO REMEDY THE ISSUE. INITIALLY, THIS DEALERSHIP THOUGHT IT WAS THE LIGHT SENSOR LOCATED ON THE DASH OF THE TRUCK AND REPLACED IT USING A WARRANTY CLAIM. ALMOST IMMEDIATELY (NEXT DAY), THE VEHICLE REPEATED THE SAME INITIAL FAILURE OVER 3 TIMES IN AN HOUR. I MADE AN APPOINTMENT WITH THAT SAME TOYOTA DEALERSHIP BUT UPON ARRIVAL I WAS MET WITH RESISTANCE DUE TO A PREVIOUS WARRANTY CLAIM FOR THE SAME ISSUE. THEY ADVISED ME IF I WANTED THE SWITCH REPLACED, IT WOULD BE TOTALLY AT MY EXPENSE. I LEFT THAT DEALERSHIP AND PROCEEDED TO ANOTHER TOYOTA DEALERSHIP WHO REPLACED THE SWITCH AT MY EXPENSE. THE REPLACING OF THE SWITCH HAS SOLVED THE LIGHTS GOING OUT WHILE DRIVING DURING THE NIGHT. I'VE READ ON SEVERAL TRUCK FORUMS THAT THIS IS A KNOWN ISSUE BY TOYOTA BUT THEY HAVEN ACKNOWLEDGED IT. LUCKILY, I CAN AFFORD TO REPLACE MY SWITCH TO ENSURE MY FAMILY IS SAFE IN THIS VEHICLE BUT MY SUBMISSION HERE IS FOR THOSE THAT CAN'T AFFORD THE REPLACEMENTS AND NEED TOYOTA TO ISSUE A RECALL TO FIX THIS SERIOUS BUT INEXPENSIVE ISSUE.
