2017 Toyota Tundra electrical complaints
Page 2 of 2: complaints 11 to 27 of 27, newest first, as owners wrote them.
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.
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).
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.
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.
Dashboard gauges do not illuminate during the day when the headlights are off. Because of this, it can be very difficult (or impossible) to read the gauges while driving in shady areas, especially while wearing sunglasses.
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.
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.
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.
Tl* the contact owns a 2017 toyota tundra. The contact stated that rodents damaged the electrical system in the vehicle by eating the soy-based wires. The dealer (modesto toyota, 4513 mchenry ave, modesto, ca 95356, (209) 529-2933) diagnosed that the wiring and the wiring harness needed to be replaced, which was an extensive repair. The manufacturer was notified of the failure and stated that there was no warranty or recall for the failure. The VIN and failure mileage were not available.
Tl* the contact owns a 2017 toyota tundra. The contact stated that the exterior and interior turn signals failed to illuminate when the turn signal switch was activated. The contact stated that the same failure occurred with the windshield wipers when the wiper switch was activated. The failures recurred numerous times. The vehicle was taken to bert ogden toyota (located at 8721 w expy 83, harlingen, tx 78552, (956) 622-4384), but the failures could not be duplicated. The vehicle was also taken to spartan toyota (located at 5701 s pennsylvania ave, lansing, mi 48911, (517) 394-6000), but they could not duplicate the failures. The vehicle was not repaired. The manufacturer was notified of the failures and opened case number: 1808292570. The approximate failure mileage was 15,000.
Mice are able to enter the air ventilation system from a large gap at the ends of the air intake grill below the windshield, once in, they enter the cab and dash area. These mice will damage the wiring and cause a vehicle system failure (braking-power-air bag, etc.) I have reported this to my dealer rochester toyota and toyota customer service (800‑331‑4331). The dealer has acknowledged that this is a issue and only suggestion was to put a scent in the cab to discourage the mice. This is serious manufacturing flaw that needs a retro fitted air intake grill to close off it's current gap that allow mice to enter the ventilation system. I have installed steel mesh to cover these large gaps (photos attached). A recall to correct this problem should be issued.
Tl* the contact's parents purchased a 2018 toyota tundra (na). While driving approximately 30 MPH, a vehicle suddenly cut in front of the driver and caused a chain reaction of sudden stops with several vehicles. The driver rear ended the preceding vehicle. The air bags and toyota safety sense system failed to activate. The safety sense feature was supposed to stop the vehicle automatically due to objects (vehicle) being in close proximity at a fast rate. The front end of the vehicle had severe damage and was towed. The contact was unsure if a police report was filed. The driver received injuries to the neck and arm area, which required medical attention. The contact was not aware if the vehicle was totaled or able to be repaired. The contact was unaware if the dealer was informed. The manufacturer was not made aware of the failure. The VIN was unknown. The approximate failure mileage was 1,000.
On july 8, 2017 we had just purchased a new 2017 tundra. We tow a 24 ft. Rv trailer and we purchased this vehicle for that reason. One of the features this vehicle has is the integrated brake control system for towing. As we were headed home on state hwy. 42 near coos bay, oregon, I noticed blue smoke coming from the rear of the pickup. I wasn't sure what happened. I stopped as soon as I could and I couldn't locate the cause of the smoke. I later learned there has been many consumer complaints regarding the faultiness of this integrated brake system controller. I want this issue fixed so I can be assured of a safe trip when towing my rv trailer without the fear of having no trailer brakes when I need them or having them lock up for no reason. Thank you
