Wiring Problems of Toyota Tacoma

In the middle of Feb 2021 the driver's side (factory) seat heater stopped heating. The seat heater button still operated normally with regard to lights, etc. I removed the seat and discovered that the connector between the seat heater wiring harness and the seat heater amplifier had electrically arced (red wire) and melted the connector together. (note: the passenger side heater is unaffected. Also note: the fuse for this circuit did not burn up as it should have when the current surged causing the melted connector. ) upon doing research this is apparently not an unheard of problem on this year/model Tacoma. I have uploaded photos. There are three issues here: 1) a clear design flaw, 2) this is a safety issue, it could have caused a fire, and 3) it likely affects the entire fleet of Tacomas in this year range. My belief is that this rises to the level of a recall and have talked to both the dealer and corporate about it. Toyota has agreed to pay half the cost of repairs, and I have agreed to this, (although they also claim to have never heard of this problem before). Toyota case #: 2103011304.

In late November or early December of 2020, I had a check engine light appear. I cycled through several hundred miles (500+) thinking it may have been a loose gas cap issue that needed time to sort itself out. The light did not resolve itself and I visited the closest dealership, autonation Toyota, in tempe. I was surprised to learn that there was damage to the engine wiring harness caused by rodents. Many manufacturers, including Toyota, have switched to soy-based wiring insulation which is attractive to rodents. The service representative pointed at 1-2 other vehicles (all new) that were in the dealership for the same problem and said they've had an increasing amount of vehicles in for this issue. My vehicle was 7 months old at this point with 6840 miles on it. The wiring harness part was a special order part and that cost alone was $1431. 79. Add in the estimated 20 hours of labor and the "fix" would be $4592. 61 at that dealership. I asked if it would be ok if I continued to drive the vehicle while we explored our options with an insurance claim. I was told the vehicle could experience a sudden loss of acceleration and cause a crash. We were able to initiate a no fault claim with our insurance company, but had to pay a $500 deductible as Toyota would not warranty this issue caused by their soy-based wiring insulation. Work was completed at the leasing Toyota dealership, not autonation. Something needs to be done about this soy-based wiring insulation issue. Not only is this type of wiring manufacturing attractive to rodents, thus causing damage that can result in dangerous driving conditions, but the wiring also deteriorates at a much higher rate in higher temperatures. (we had a BMW 550 with soy based wiring that was disintegrating in the headlight housing. ) manufacturers need to stop producing soy based wiring insulation or improve it to repel rodents.

Electrical wiring/connector for the heated seat module located under the driver seat overheated or arced causing the connector (s) to melt posing a safety hazard and rendering the heated seat inoperable.

Tl the contact owns a 2013 Toyota Tacoma. While driving 40-45 mph the heater/ air conditioner unit became inoperable as smoke was entered the vehicle through the vents. The contact noticed the wires were melted and disconnected the wires from the coupling. The vehicle was taken to Toyota of kingsport (2525 e stone dr, kingsport, TN 37660) where the failure was diagnosed that the blower motor overheated]. The vehicle was repaired. The manufacturer was not contacted. The failure mileage was 80,000.

The entire frame of this garage kept truck is completely rusted though. This truck as only 61,000 miles on it & is unsafe to drive. The rear leaf spring mounts are broken & have punctured the gas tank. The electrical wiring to do with the safety neutral switch, which is tied into the entire from wiring harness has caught fire twice. Toyota has been notified about all of this, in detail, & they could care less about my own or anyone else's safety. There isn't a scratch on this truck & has really low miles yet is so unsafe to use because of poor construction on Toyota's part.

Truck with only 8000 miles has over 3000 dollars damage from rodents chewing on wiring. . . . Research online shows that there are class action suits as many people are experiencing this problem of rodents being attracting to "soy based wiring". When I paid almost 40,000 dollars for a new truck , I mistakenly thought id be trouble free for at least 3 yrs or 36000 miles. . . I have insurance but must pay 1000 dollars deductable and without truck for approx 3 weeks and now also the possibility of this recurring again. Im sure the intentions were good with the soy based wiring. . . Ie, less plastic in landfills. . . . But while this problem has always happened, never this often and repeadedly. . . A simple google search of Toyota soy wiring should enlighten anyone . . .

Tl the contact owns a 2016 Toyota Tacoma. When the vehicle was started, the check engine and traction control off warning indicators illuminated. The vehicle was taken to freeman Toyota (2875 corby Ave, santa rosa, CA 95407, (707) 535-2330) where it was diagnosed that rodents entered the engine compartment and chewed on the camshaft sensor wiring harness. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 21,600.

The wiring harness cable from the sensors to the computer burnout and the seatbelts doesn't respond right especially with his unraveling and doesn't lock good or pool and the master cylinder it's not function correctly either it's like it's not stopping the brakes are not stopping I know the vehicle is old but still this is a defect and very has for the drivers of all the vehicles my 1998 Toyota Tacoma sr5 2. 4 liter 2 wheel drive.

I recently purchased a 2106 Toyota Tacoma, this vehicle has been owned for about 4 months and has less than 4,000 miles on it. I was alerted of a check engine light and took this to the dealer for repairs. I was told that the wiring harness had been chewed by a rodent and this was very common at this dealership. I didn't think anything of it until I went online and notice thousands having the same issue. This is not just a one time thing or a chance occurance. There are several pending class action lawsuits against Toyota for defective wiring and engine components that are made of a soy based product that is a principal source of some rodents diet. This makes the engine components irresistible to rodents. Honda, Toyota and Ford have all been experiencing higher than normal issues with this since switching to this product. What makes this worse is that there is no solution to the problem. I cannot move or relocate because of the wildlife, squirrels are everywhere. Additionally, the dealership snickered with put some moth balls or make some homemade rodent repellant. Unfortunately whatever spray or toxic repellant you use around the engine, will eventually be breathed into the cabin which could become deadly. This also could affect drive that are in motion or could leave them stranded on the side of the road. Luckily for me, my car was parked and I was alerted by the check engine light and able to drive the vehicle to the dealership. Of course the dealership did not cover this on the warranty and Toyota could not be reached for comment directly due to pending litigation. This has cost me over 3,000 dollars in repairs and there is no telling how many more time I will have to pay this before Toyota fixes this problem.

It cost me $850. 00 because Toyota used soy based wiring on my vehicle. A rat chewed wires under the hood causing this damage. There are class action suits against Toyota for this problem.

Rodents caused over $3,000 in damage by chewing on cables that are made from one or more of the following (soy, rice husks, wood, sugar, vanilla, peanut oil, and straw; references:. . Read more...

Electrical wiring was eaten by some kind of rodent - twice! dash panel lights came on, so I took it to the dealer since it was new. Dealer reported that the electrical wiring had been eaten by some kind of rodent. The repair was make ($500. 53 discounted), and the first night the truck was back in front of the house - it happened again. We live in the city with many vehicles parted in the street. I have lived in the same house for over 27 years and have always had a vehicle parked in my drive way with no rodent problem. Why now? why this vehicle? according to a dealer service person (and collaborated on-line), car manufacturers (Toyota included) are trying to become more "green" and have begun using more peanut and soy products in the manufacturing of its wire insulation and rubber hoses - thus attracting animals. Also, the design of this v6 engine has a space just under the engine cover that small animals fine inviting and warm. The animal go into this space and naught on the wires that are present. My local dealer covered the second repair, and was great to work with. However, there seems to be a design/manufacturing issue that is out of the control of the dealer. My solution = fill the space with chicken wire. So far. So good.

Took our 2005 Toyota truck into the Toyota dealer for a check engine light p0333. They said that it was a cable that was previously replaced by another Toyota dealer due to rodent damage. Since the car only has 2000 miles since that repair and a total mileage of 12,000 miles we found it unbelievable that they would quote us a "discounted" rate of 2,318. 00 to repair the cable again. We told them that we did not want to spend this much money on a car that only had 12,000 miles. The car got repaired at a fraction of the cost they wanted and it turned out that they had not tighted down the intake manifold and unplugged a sensor on startup. Their cost to repair with a supossite 8 hour discount was 2318. 00. The eventual cost from a normal mechanic was 374. 00. It should have been less but the extra time to correct their errors cost more money. On the internet there are many owners of this same type of vehicle complaining about this type of damage being caused by rodents eating into critical wiring. Wiring that cannot be repaired without the Toyota dealer charging 3000. 00 plus for labor. This is a scam. It would be easy for the Toyota engineers to fix this cable so that it could never be eaten by anything again. Also my mechanic and others have asked "why do they eat this cable and no others in the same area"? they are obviously making the wire coating out of materials that attract the rodents to it. This is a cash cow repair for them and they are not about to make it so that the rodents do not eat it. A normal mechanic charges 374. 00 to repair this problem versus 3000. 00 for the dealer! this is professional robbery through design and should be investigated from a federal stand point. I have all of the paperwork and the cable that is in pristine condition except for the eaten away end if your department would like to examine it.

Both front marker light lenses are melting and the lamp socket is charred brown. The plastic lens is burnt brown and cracked. After driving for just a half hour, the plastic lens covering the marker light was soft and very hot. The hot marker lights were always on when driving, as as the directional turn signal lights. This a factory design defect. At what temperature will the plastic lens or socket wiring start an electrical fire? . . . Updated 11-06-13.

Used my 2006 Toyota Tacoma prerunner to tow a vehicle a short distance before a short circuit in trailer wiring caused wiring fire in prerunner---30 amp fuse in Toyota failed to protect circuit, leading to total truck wiring meltdown and ruin. Fuse was of the ampacity required by Toyota--30 amps. Truck was purchased new, never involved in an accident, and no changes had been made to wiring or fuse systems. Auto electric repair shop required $2800 in parts and $2000 for labor to repair melted wiring looms and fuse box; they suggested that failure could have resulted because Toyota uses a 30 amp fuse on a #12 wire circuit that will melt and burn before the fuse blows. (12 gauge wire typically must be protected by a 20-amp fuse. ) Toyota (corporate) refuses to deal with my issue or talk to me about whether the failed fuse and meltdown could have been caused by their installing a fuse with too high an ampacity rating because I did not have the repair done by a Toyota dealership. Is there a dangerous design flaw with the prerunner? I am certain that I did nothing to my prerunner (as its only owner) to explain why the truck nearly burned up and the wiring system melted down (and was completely ruined) simply because of a simple short circuit in the trailer I towed for less than one mile (before meltdown occurred). I am hopeful that nhsta may be able to use my information to approach Toyota on the potential design defect issue and, certainly, to collect my complaint with any other similar complaints that could denote a trend or serious safety risks with the Toyota truck's wiring system.

Copy of letter to Toyota concerning a defective spiral cable and electronic circuit; feels this part should have been repaired and covered under a special safety warranty or recall; enclosed automotive part fwd to nvs-200 the consumer stated the air bag light illuminated 12 days after being at the dealership to have a recall problem repaired. The dealer informed the consumer he would have to pay $88 to diagnose the problem. The dealer stated the problem was due to a broken spiral cable and electronic circuit underneath the horn which would cost $ 496 in addition to the $ 88.

I do not see the recall for the spiral cable assembly on my Tacoma. I read that this VIN is part of a recall for the wiring in the steering wheel that controls my passenger airbag, cruise control and some other functions. It has malfunctioned. Why is it not listed on your website? when I checked on the status of this recall, it shows that my model, according to the VIN does qualify for this. My passenger airbag is not working, and my cruise control is no longer working at speed.

Toyota denied me help with things that should be a recalls! they are greedy and out right lying sociopathic thieves! the top rear brake light on my Tacoma 07 truck lets rain water in. This is goin to cause mold and has already blown out the compass on the ceiling as the wiring for this is in the ceiling! and seats gettin wet over and over from rain water gettin in the top rear light. They also just denied me any help refunding me for updated headlight lens that had to come out with which kept burning sockets, blowing bulbs and burning the lens! there TSB which should be a recall is t-sb-0129-11. This TSB thing is a scam so they dont have to account for their poor quality mistakes. I paid 24,000 for this truck and Toyota wont help me at all with their defective product! they are pure evil! there is no way I can get water in the top rear break light, no way whatsoever, theres no way I can burn out sockets and lens over and over since iv owned the truck! people dont go to the dealerships because they are rude as hell! they have no idea what theyre doin in first place and they pull scams left and right. They said they wont help cause I dont go to dealership enough can u believe that??? im not out of reality at all, I dont use facebook , I dont drink or drug, I am in no way out of reality whatsoever! I do nothing that results in irresponsibility in any way shape or form! I dont spend money everyday goin down a river. Im very conservative and meek. This is enough ! I can no longer deal with them scamming people ! im sick of it! please do ur job!

After running the vehicle and shutting it off for about 2 hours the vehicle did not want to start, there was only about 2,000 miles on the truck. The starter is cranking the engine, but the engine is not starting up. I took it to the Toyota service department, and they said nothing was wrong with the vehicle. The same thing happend severl times after I had taken it to Toyota. The only way to start the vehicle would be to crank it up for about 5 minutes, then the vehicle would run rough for about a minute. I took it to the Toyota service department again and this time they worked on it. They said they had to change the throttle position sensor, the engine wiring harness, and the fuel injectors. No old parts were available. Problem has still not been corrected. Vehicle now has about 6,000 miles and every 3-4 days it still doesn't want to start up.
