I gave yesterday a complaint (9/24/25 complaint #11689593). Today at the same location, exit ramp of the az 101, going west, the same thing happened. Today, 9/25/25, as I was approaching the car that was waiting to enter 56th street my engine increased from about 5 mph to about 35 mph. Instead of hitting the car in front of me I turned into the lane on my left. A car hit my car on the left side. My car isn't safe to drive!!.

As I was exiting a highway, and my foot was on the brake, the engine increased from about 15 mph to about 30 mph. I had to put the car in park. I almost hit the car in front of me. The engine increasing like this happens when I slow down for a red light or stop sign.

Subject: vehicle safety & emissions complaint – Toyota Camry (VIN [xxx] ) dear office of defects investigation, I am reporting a safety and emissions defect with my 2019 Toyota Camry xse (VIN [xxx] ). • at 78,736 miles, techstream confirmed dtc p26cb71 – engine coolant pump actuator stuck. • this fault risks overheating, sudden engine failure, and emissions non-compliance. • covered under csp 24te04 and federal emissions warranty, but seminole Toyota and autonation Toyota winter park refused repairs and demanded $1,616. 46. • Toyota corporate ignored my formal demand and deadline. I request NHTSA investigate, as this issue impacts safety and emissions compliance and could warrant recall action. Attached: diagnostics, csp letter, invoices, photos, correspondence. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle cut off at a stop light twice.

Unknown loud noise while driving occurred once. 5 mpg decrease is gas mileage. My assessment is a defect in the ecvt / power split device related to one of the electric motors.

2018 Camry with very low mileage (appx 38,000) and had all its required services done, suddenly had a check engine light. Less than a minute after that, "coolant temp high - stop where it's safe" message popped up. Service center indicated it was a failed water pump (diagnostic codes p26cb71, u0073, u016387, u0163, p26cb). Coolant was gone. Multiple users for 2018/2019 have reported this water pump failure on r/camry [xxx] does not seem safe to have a car go from no problem to near catastrophic engine failure with virtually no warning information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2019 Toyota Camry. The contact stated that while driving at an undisclosed speed, there was an abnormal humming sound coming from the engine. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was determined that an unknown part inside the transmission had oxidized. The contact was informed that the transmission needed to be replaced. The contact was advised that the engine mounting insulator sub-assembly and the hardware machine rotor for the braking system needed to be replaced. The vehicle was not repaired. The contact stated that the failure persisted. The contact stated that in June 2023, the transmission was replaced. The manufacturer was not made aware of the failure. The failure mileage was approximately 109,000.

2019 Camry se would not accelerate and rpm’s would escalate without making car move. Car has had complete maintenance on a regular basis. There have been no prior lights on or alerts until my son’s car stalled in traffic almost leading to side collision. Once it was plugged up to computer shows faulty transmission (complete transmission failure) and engine coolant bypass valve which I know has a tbs report on yet my local dealership refuses to do anything with it unless they charge me to hook up to their computer first and deny any issues with this car. I have read hundred of others with the same complaint and numerous lawsuits yet Toyota refuses to recall and fix the faulty transmissions in these vehicles. Something needs to be done before someone is killed, as my son could have been when his car stalled in middle of traffic and transmission failed with no prior warnings.

The contact owns a 2006 Toyota Camry solara. The contact stated that while operating the vehicle, the check engine warning light illuminated and remained illuminated.

Incident highway malfunction occurs – [xxx] while driving at a steady speed on the highway, my 2020 Toyota Camry unexpectedly shifted gears on its own. I did not bump the gear shifter or interact with the controls in any abnormal way. The gear shift occurred without warning or driver input, while the vehicle was in motion. A “drive start control malfunction” warning appeared on the dashboard at the time of the incident. Vehicle towed to Toyota service center – July 11 2025 following the incident, I brought the car to a Toyota dealership for diagnosis and repair. I spoke with a service advisor named rebecca, explained the situation, and clearly stated that I did not hit or touch the gear. The vehicle was kept for inspection, repair and I communicatied with Toyota. Vehicle picked up – July 16, 2025 I picked up my car from the Toyota dealership on Wednesday, July 16, 2025. I had not yet heard back from Toyota about coverage or resolution. I chose to wait for further communication regarding whether they would take responsibility for the malfunction. Toyota corporate follow-up call – July 23, 2025 on Tuesday, July 23, 2025, Toyota corporate called to inform me that the repair would not be covered, citing that the vehicle is out of warranty. What disturbed me most was that the representative claimed I had told rebecca that I might have “bumped the gear,” which is completely false. I made it clear from the beginning that I never touched the gear shifter, and that the malfunction occurred while I was driving normally. This false statement was either a miscommunication or a lie — and it minimizes the seriousness of a potential safety defect. Response to Toyota’s misrepresentation – July 23, 2025 during the call, I told Toyota that misrepresenting my account was unacceptable and dangerous. If Toyota is aware that this vehicle model may experience uncommanded gear changes while in motion and fails to report. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The engine quit running whenever the headlights, turn signals, or wipers were turned on. This was obviously a serious safety problem when driving! it began intermittently on 6/30/25, but it became a consistent problem by 7/7/25, so I took the car to the closest Toyota dealership for evaluation. I can provide their service report to you if requested. It took them 6 hours and $1000 to diagnose the problem as bad electrical grounding points (high resistance), which were only revealed after they removed the front bumper. In my opinion, it is an unsafe design to have poor grounding for headlights cause the engine to die.

Component/system failed: the electronic control module (ecm) and related wiring were compromised by a dealer-installed lojack anti-theft system. The device was spliced into wiring near the airbag system and ecm, causing repeated faults. The component remains in the vehicle and is available for inspection. Safety risks: 1. Wiring near airbags may interfere with deployment. 2. Ecm faults risk stalling, loss of power, or emissions failure. 3. Hidden wiring increases short-circuit risk, especially near coolant areas. 4. These conditions place driver and passenger safety at risk. Problem confirmation & inspections: the issue has been reproduced in multiple dealer visits. One Toyota dealer identified the improper lojack installation as the likely root cause. Service records are available. Warning lamps: yes. Check engine lights and warning messages appeared within months of purchase and continue intermittently. Summary: the car was sold as a Toyota gold certified pre-owned (cpo) vehicle, advertised as thoroughly inspected and protected. In reality, it contained an undisclosed modification that created hidden defects, repeated ecm errors, and safety concerns. Concern: the ecm is covered by the 8-year/80,000-mile federal emissions warranty and the 7-year/100,000-mile gold cpo warranty. Yet Toyota denied my arbitration claim as “ineligible. ” if such cases are refused, it means dealers can install aftermarket systems, charge buyers, and avoid accountability. In that situation, the Toyota gold cpo program becomes meaningless—a consumer deception rather than protection. Request: I respectfully ask NHTSA to investigate whether dealer-installed systems like lojack pose systemic safety risks and whether Toyota’s warranty and arbitration processes are adequately protecting consumers.

This vehicle, and models with the same throttle body and air filter/air duct assembly have an issue. Where plastic parts from the vacuum box attached to the air duct come loose and get stuck in the throttle body. Causing the engine to rev up then die. I have dealt with this same issue twice in the last three weeks. Thank you for your time.

When I either: I) start the car and drive more than 20 ft or ii) am at a stop light then accelerate. . The car begins to jerk backward. Have changed the gasket and the throttle body and this issue still keeps happening. It started around the 90k mile mark.

Uncontrollable sudden acceleration 3 times while I drove the car, it suddenly and rapidly accelerated. Eventually, the car crashed and was totaled. The first time was 3/31/25 when my wife and I went to the car wash. To exit the car wash, I put the car in drive and lightly applied the accelerator pedal and suddenly the car accelerated rapidly and made a loud noise. I immediately braked and the car went back to normal. Over 3 years nothing like this happened before. The 2nd time was only 8 days later. On 4/8/25, I was driving the car at moderate speed in the center lane of a large street and while changing from the middle lane to the right lane to prepare to turn right at the next street, the car started accelerating rapidly and to make a loud noise. Fortunately, I was able to brake and the car went back to normal. We went to the Toyota dealer the next day 4/9/25 and told our concerns to the service advisor and the shop foreman. They checked the car, including with a computer. The foreman and I both drove the car. He said they did not find any mechanical/electronic issues and the only explanation is that if I hit the cruise control (which I never use), as he saw my hand close to that button while I drove. He said to avoid the cruise control and it will be ok. They did not charge us for the visit. The third time was on 6/15/25 when we again went to the car wash. I was very careful as this was the same location as our first time. Just like before, I lightly applied the accelerator pedal and suddenly the car accelerated rapidly and made a loud noise. However, the acceleration was much more rapid than before and I was not able to brake in time and the car crashed into the pole of the car wash about 45 feet away. The airbags deployed and the car was totaled. We were pulled from the wreckage and ended in the emergency room. Luckily no one was seriously injured. Enclosures: my 4/8/25 text, 4/9/25 dealership visit paperwork, and photo after the crash on 6/15/25.

While driving at speed over 45 mph or going up a steep hill car starts to shutdown and shudder causing a serious safety concern. I could have been killed. I understand this is related to oil consumption problem that Toyota has failed to address in the 2014 model. What can be done? this is criminal!.

Been having an issue for months now and the dealership was absolutely no help.

I could not crank my car, all the lights were on, on the dashboard, reducing power, stuck in limp mode.

Low braking power message is on and brake to floor and vehicle does not brake properly cause: diagnosed concern, found vaccum pump not producing vaccum causing concern, inspected and found vaccum pump broken and camshaft broken, pieces broken off inside engine. States low braking power message is on and brake pedal drops to floor and vehicle does not brake properly.

I am reporting a brake failure issue that matches the symptoms described in NHTSA campaign number 19v-544 (Toyota recall for brake booster vacuum pump failure). My 2018 Camry has experienced loss of brake assist, making it difficult to stop safely and requiring excessive pedal pressure. Despite these symptoms and the known recall for this issue, my VIN is not currently included. This raises concerns that the recall scope was too limited and that my vehicle should be included. I have contacted both the dealer and Toyota corporate, and I am requesting that NHTSA investigate this defect further and consider expanding the recall. This is a serious safety issue.

The car accelerated uncontrollably for no apparent reason. I was pulling into a parking slot, preparing to put the car in park and stop the car. All of a sudden the car accelerated and slammed into a building.

Awd hybrid vehicle makes a noise at speeds under 20mph , that sounds like an electric motor or bearing - salesman said the noise is a mandated law by NHTSA ? or ? month later the maintenance tech forman took it for a test drive and said the same thing . That the noise was created (by a speaker ?) so the vehicle can be heard at low speeds / below 20 mph . I asked where the speaker is , he said he didn't know ! I asked if he could show me it on a diagnostics screen , he again refused . The noise sounds exactly like an electric motor . Mg1 , mg2 ? I can't hear the noise when backing out of a driveway or similar low speed situations ? I need to verify if this is true - is there an actual law that the vehicle has to make a noise ? and it was okayed to use a noise that sounds like the hybrid electric motor or bearing ? even if this is true the computer logic should be changed so that the sound pulses so that it is obviously a speaker and not a mechanical issue . ( like no grease ) and it should always work when it is most needed , backing up and slow driving / all the time under 20 mph . Service department should plug in a diagnostic scanner and prove to me that a speaker is making the noise . * why is this a safety issue ? because if they are lying , eventually ( when it is out of warranty ) this vehicle will break down . Are all 2025 Toyota hybrids making some kind of noise ? and if it is a noise created by a speaker - prove it are all 2025 Camrys making this same noise ? maybe they all have the same mechanical problem ? why wait till there is a crash , fire , or an accident ? as in the next section - additional details . And again if it is a legitimate noise generated for safety . At the least change the computer logic so it pulses and doesn't sound like a bad motor generator bearing . And have the maintenance techs trained to know where the speaker actually is . I don't want to share my personal information with Toyota . If they are lying.

This was a recall due to the coolant valve Thursday, my vehicle had went in for the recall I picked up my vehicle Friday morning I checked to make sure the part that they have changed nothing wrong with it or not. When I looked at the part a day after I noticed pink stuff is leaking from around it this was announced by Toyota this is the new part they had just made I’m assuming and it is still leaking I have a 2020 Toyota Camry. With 141,000 miles. And now I am having issues. Toyota needs to redesign this piece or have a further investigation on it.

Engine—was told by dealership that we needed a new motor because of lack of oil in engine - had not seen oil drips or any smoking out of muffler. No lights on dashboard. Only been serviced by dealership. Told us; we needed to keep check and add oil as needed until we decided on a new motor or trade. Either is not a good option because of expense. We are probably going to bite the bullet and have to trade with not being able to get much out of trade because of this. The car is in very good condition, no wrecks and had hoped we were to get more mileage. We keep check and add oil. Know this is just a complaint, but am sure others had same problem.

Intermittently, when leaving from a stop the car will have just enough power to pull forward about a car length before losing all drive power. The engine revs, but behaves as if it were in neutral. This happened a couple times when making a left turn from a stop sign leaving the car in cross traffic, powerless, with cars coming from the drivers side for a second or two before it had power again. It seems to happen in hot weather. It is intermittent. The dealership could not reproduce the problem. There were no warning lamps. I could make the vehicle available for inspection upon request. The first appearance was last summer. It did not do it over the winter. It happened again yesterday. When it happens it tends to happen for a few minutes before driving normally again. It may happen at start up or after the car has been driven for some time.

Check engine light went on and the car’s temperature gage started going up rapidly. Pulled to the side of the road and turned the car off. The problem was the electric water pump and thermostat which I bought at Toyota parts, the car only has 29,090 miles on it.

The contact owns a 2009 Toyota Camry. The contact stated that while his daughter was driving, the "check oil" warning light illuminated. The contact added oil to the engine. The contact was informed that the check oil warning light was illuminated. The contact took the vehicle to the dealer where an oil consumption test was performed. The dealer diagnosed the vehicle and determined that the engine was consuming an excessive amount of engine oil. The contact was adding several quarts of oil every 1,000 miles driven. The vehicle was not repaired due to cost. The manufacturer was made aware of the failure and informed the contact that the extended warranty had been exceeded. The failure mileage was approximately 137,000.

Vehicle will stall out in the middle of driving as if it does not have any fuel. Toyota could not pull the error code a second time replaced a random part and the next month the car continued to stall out.

Excessive oil consumption after 1000 miles low oil pressure warning comes on.

Only when it rains the forward collision warning light comes on. The last time it came on the engine light also came on with code p01280. Diagnostic at Toyota said the thermostat needs to be replaced. I decided to look into this as the thermostat should not be bad at 54500 miles. Weeks later and the neither light has come on again.

I started hearing a "noise" over the course of 2 weeks. When the accelerator was depressed, the vehicle never accelerated. The vehicle also seemed as though it was losing power, but no lights ever came on. I have only taken my vehicle to the dealership to be serviced. The maintenance has been done regularly and without fail. When I brought the car in for regular maintenance I had them check for the noise and they said they didn't find anything. I took a video before leaving for work the following day, and brought the car back. Because it sounded it was coming from the wheel well they charged me for a diagnostic and said one of the plates for my brakes was bent. The following day it was still making the same noise, but when I went to accelerate the car shut off in the middle of a major highway and then the check engine lights started flashing. I took it back to the dealership and they claimed it was an air flow component, said it would be repaired, and kept the car for 5 days. After the repair, it was still making the "noise" and that is when they said it was the transmission and I would be responsible for the repair. This happened at 150,098 miles. Needless to say, I will not be paying for that repair. I believe this is a Toyota issue and the customer, especially one who has been religious in maintenance and upkeep, should not have to bear the cost of a their design failure. I was also told although in the maintenance manual, Toyota has decided against flushing the transmission because it is sealed. No warning lights, messages, or anything of the sort ever appeared until the check engine light came on.
