This is a complaint with Toyota. I bought my 2011 Toyota Tacoma pre runner sport brand new. this is a complaint with Toyota. I bought my 2011 Toyota Tacoma prerunner sport brand new. About a year ago, I noticed my amber "daytime running lights" were becoming discolored, it had the appearance of the bulb becoming hot, melting and discoloring my amber lenses. At that time it was just starting to turn colors. Last week a man at the gas station pointed at my drivers side running light and said I should have that looked at before it burns through or causes a fire. Upon his comment I noticed it had become noticeably worse, to the point I do not feel like the vehicle is safe to drive with the running lights on, you can not turn them off during daytime driving, it is a safety matter. I immediately contacted my Toyota dealership service rep in tracy, CA, tracy Toyota, he said there was nothing they could do and gave me the Toyota corporate office 800 number. Today I talked to two employees who were sympathetic but ultimately said nothing can be done by them and I was told by them a letter was mailed out regarding this defect, the letter confirms it as a known defect and the letter shows Toyota has acknowledged it as such. My warranty has since expired. I never received the letter and they refuse to pay to repair for this defect. This problem still exists for 2011 Toyota Tacomas. I have to pay out of pocket to replace both headlight running light assemblies, I am requesting Toyota to reimburse me the cost as I will keep the receipt and ask for the damaged parts. This defect diminishes the safety function of a daytime running light and could cause a fire as well.

The check engine light and the trac off light came on as I was merging onto the interstate. I immediately stopped the vehicle, pulled over, and took my 2012 Toyota Tacoma with 78,000 miles to the mechanic where I left it overnight for them to look at it in the morning. Running a diagnostic they found code p2443 - secondary air injection switching valve stuck. I asked if they had dealt with this before and they said this is a common problem for Toyota and they have done recalls on both the tundra and sequoia models that have had these issues, but the Tacoma hasn't had a recall yet, even though it seems to be just as common with the same parts. They said the cost of parts and labor would be around $2,000. When I asked them if the vehicle was safe to drive off their lot they said these codes can cause the Tacoma to go into "limp mode" where you can loose power, acceleration, and won't be able to go over 45mph. I hate to think what could have happened if I had kept merging onto the interstate and tried to get up to speed only to "limp" into traffic or if this had happened a minute later on the interstate! every thread I read online from multiple sources show people having similar issues from as low as 1,000 miles on the truck. The issues with the secondary air injection pump and switching valves seems most common between 50,000-80,000 miles, but eventually does happen in the 2012-2015 tocoma models.

Failure Date: 10/17/2017

Drivers side door handle fell off, while stationary. I grabbed handle to open door like normal, and part of it crumbled im my hand and then fell to the ground. It could not be put back on due to excessive corrosion. This is a huge safty risk of someone getting trapped in the vehicle if something happened and the handle fell off at the most importuned time, it could easily cause fatalities. While searching for a replacemet part I met several others with this same problem. The fact that Toyota is charging and exuberant about for the handle assembly�s ($4251.

Failure Date: 07/10/2017

Driving at high way speed; the abs light, parking brake light, traction light, lost power to windows, a/c, radio, power steering, engine was running rough, then the check engine light came on. Could be a safety issue of control of vehicle for drivers not paying attention. Toyota dealer said the root cause was a bad cell in battery that caused the ign#2 fuse to be blown. These batteries have known issues to be bad from the factory. Reported earlier about 30000 miles the factory battery would not start vehicle and dealer said they replaced because of a bad cell. I own a 2008 Toyota Tacoma also , same model and make as being reported and that battery has been replaced 2 times for same reason.

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.

5tflu4en0bx007991 lightning/electrical I want to report safety issues with my totyota Tacoma. When I bought Tacoma in san antonio, brand new in 2011, a few months later the daytime running light (drl) and turn signal lens become distorted, bubbled, and cracked. I did a google search, and it was an extremely common issue with many owners complaints. I told my dealership and it was "normal" and I was required to pay to get it fixed. Earlier this year when I was at mountain states Toyota in denver to get the oil change, I inquired about the same issue. The employee told me that it was a very common issue, and that Toyota will fix it for free. I was told that a letter was mailed out to every person that owns a 2011 Toyota Tacoma. However, there was a time limit to get it done and it already already passed. I want to emphasize that I never received a letter from Toyota. In addition, my truck has always has electrical issues since I bought the truck. Intermittently, when I drive my truck, every electrical components and lights, including from the instrumental panel would shut down and instantly start back up, and my steering wheel would momentarily lock up. I called Toyota headquarter, and the lady I spoke to said that there was a time limit when I could get it fixed, and that it has now expired. And that there was nothing she can do about it. I only want Toyota to fix this issue free of charge, because I never received that letter they told me they sent out, and I do not know why they put a time limit on it. If Toyota refuses to get it fixed, I want to put Toyota on notice that I want to initiate arbitration with Toyota.

The hvac fan electrical connection burned and melted. I could smell burning inside my truck. My mechanic found the hvac blower fan connection had been so hot it burned and melted along with the resistor. Some of the wires were black and brown. I was worried the truck was going to catch on fire! this happened while I was driving. After looking online I found I am not the only person who has had this happen! Toyota denied the problem.

Failure Date: 06/02/2016

My truck was recently damaged from rodents,they built a nest by engine and chewed wires. After further research I found that auto manufacturers in order to go green are using soy based products on wires instead of petroleum. They are using sugar in there plastics. Rice husks in there interiors. All this stuff attracts rodents. This is unacceptable! my dealership said they are seeing at least 2 rodent damaged vehicles a week. My truck is driven daily and sits no longer than 8 hours. The total damage on a brand new truck with extended warranty was 2700 out of pocket, this damage was no covered by warranty.

The secondary air injection systems seems to fail quite frequently on these 2012 Tacomas with little to no help from Toyota to take care of this issue as a recall. These are known to fail right after your out of warranty and to charge it's loyal customers over $1000 for a part that should not fail or a part that should be covered is absurd. I have been a loyal Toyota customer my whole life but the issues of the Tacoma are making me rethink my decisions as an automotive consumer.

After driving on the highway for a few minutes at ~70 mph, the abs light run red on. When the light turned on the computer thought the car was in a bad situation and locked the brake pedal. This caused the brakes to not function and made the car almost impossible to stop. Whenever the car was able to be slowed down to about 19 mph, the light would turn off and the brakes would start to function normally. This happened once a week for 3 weeks in 2015 and again in February of 2016. It happened again in April 2016. This problem did not happen at low speed and it would not happen twice in the same day, even during the same conditions. I went to wolfchase Toyota to fix the problem. They decided not to do anything about it. I went to principal Toyota and they said they had never seen the problem before. They said that they could reset the computer or put in a new one ($3000). They reset it and for the past few months it has worked.

The contact owns a 2016 Toyota Tacoma. While driving at various speeds, the estimated mpg displayed on the message board was inaccurate. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle; however, the computer was reset. The technician also stated that the estimated mpg of fuel consumption was not calculated when the vehicle was idling. The failure persisted and the manufacturer was notified. The failure mileage was 1,000.

After 10,000 miles the airbag light came on. Then the next day the check engine light came on as well as the traction control. Called the dealership and they looked at it saying I just need new sensors. Drove it a couple more days and noticed the cruise control was non existent. I drive a lot for work and use it a ton and all of a sudden it wouldn't even bring the light on or work at all. The next day started driving and the real issues started. Turned truck on; same problems I have been having; then the truck would not shift. Kept going and going till I was getting to 5000rpm and it shifted with a tremendous amount of force. Once it shifted the whole truck did a huge jerk then went a little more an did a double shift totally bypassing the 3rd gear. I turned it off and started it again. Kept having the same problem all day. I called the dealership and they said get it to them when I could and they would take a look. Almost caused several accidents trying to get the brand new $35,000 truck that didn't work to the dealership almost running into the people in front of me who cut me off because I can't go over 40mph on the freeway and I have no control of the violent shifting moving the whole truck. Needless to say the dealership tried to blame me for all of these problems that I could not have possibly cause if I tried and that my brand new truck with 10,000miles on it was fine just needed a couple sensors. Obviously this is not working and I think sensors are the least of the worries.
