Camera / Radar component - yes Camera / Radar unit is available When it failed, the dash lit up with lots of errors: engine check light, anti-skid failure light (even though the system was turned off), rotating errors included: secondary brake system malfunction, pre-collission system malfunction, LDA system malfunction, check engine. I was driving up a 6% hill on a four lane road at 65 MPH with the cruise control active. Was in the left lane passing two slower trucks when the engine just seem to die and the dash lit up with lots of errors. By the time I was able to get to the right lane and off the freeway, I was doing less than 20 MPH. It turns out that when the radar / camera unit failed, the computer put copious confusing errors and put the engine in limp mode. Very dangerous and I'm lucky there wasn't more traffic. When the computer detected the failure should have automatically disabled the cruise control and put out an error message saying it was now disabled. The other junk errors just confused everything. The computer definitely should not have put the engine in limp mode. It was only after I pulled over and had time to digest the errors that I actually figured out what had happened and how to handle the situation. After I pulled off, the center display which had been saying there was a message that would display after I was safely stopped, now had an message indicating I should turn off the cruise control. Problem was I could not determine if the cruise control was active or not because the indicator was blocked by errors, however the engine was still definitely in limp mode. I finally turned the engine off and back on to make sure the cruise control was off. All the rotating errors and error lights were still on, but the engine was now out of limp mode and the car was again drivable.

At 170,000 miles, the 2019 Toyota Hybrid Camry LE has developed a consistent drive train lurch/stumble/shake around 20, 40 and 60 MPH, which is increasing in intensity and occurrence. This defect is quite startling and occurs regardless of efficiency, HVAC, cruise control, etc. settings. Examined twice by a Toyota dealer service department Toyota-trained licensed repair technician, no explanation or repair can be suggested. That is, I am expected to suffer this defect until left stranded.

Owner bought new 2021 Camry XLR 4 cylinder all wheel drive. It currently has 39,000 miles on it. No problems until January 25, 2026. It was 11 degrees below zero, my car had the original battery. Car started without issue, I return to house to "warm it up" prior to driving. Upon my return I had multiple error codes; 1. AWD System Malfunction, 2 WD Engaged (Visit your Dealer), Secondary Collision Brake System Malfunction, Pre-Collision Brake System Malfunction, Parking Brake Malfunction, Check Engine light. I did NOT drive the car that day. Once the weather warmed up in Iowa, the number of codes would change and sometimes absolutely NO codes. Upon extensive internet research, I purchased a new battery (old battery did "test" ok, but no load test was completed). During all of this time, my car has always started well, performed well, etc. HOWEVER, when the "codes" show up, my cruise control also will not work. . . . Original dealership "ran computer codes" (C059746) indicating "calibration memory failure."Quote was given for: Parking rake actuator replacement $1,760. 2nd Toyota dealership opinion: $3,300 for parking brake actuator, low pressure fuel pump replacements. Original dealership adamantly denied the need to fuel pump replacement. Again, my car intermittently may or may NOT show warning codes. . . .Not I dealership has conducted any examination, they simply "run the computer codes" and quote a repair cost. I am concerned about repair scandals, diagnostic incompetence and perhaps the CAUSE of my "error codes" has not even be addressed (computer glitch, faulty sensor, corroded wiring, etc.) I am a 70 yr old female still working and needing transportation. I spent $34,000 on my car expecting safe and reliable transportation. I have NO confidence in the Toyota Repair diagnostics. I also own a 2005 Toyota Camry which was involved in the Toyota acceleration debacle years ago, of which they decline any responsibility. Luckily, no human injuries!!!!!

I own a 2018 Toyota Camry XSE. The car is equipped with a radar cruise control and automatic braking system that will brake the car if programming believes there is risk of an accident. The problem is this is all front-based monitory and no rear based monitoring. Recently I was traveling the speed limit on a 4-lane highway when a car stopped abruptly in the turn lane in which I was following. There was no need for my car to brake abruptly as I was not traveling so close behind the car in front of me to justify that. Rather, I was more concerned about a car behind me that was tailgating me. I wanted to brake gradually to give the car behind me time to stop. But the auto braking system in my car braked so suddenly against my will causing the car behind me to veer off the road onto the shoulder in order to avoid rear ending me. It also made me worry that the driver of the car behind me might believe I intentionally braked hard to make him back away from my car when this was not the case. The 2018 Camry XSE auto braking system is a hazard because it looks forward with the radar but did not consider the car tailgating me and it nearly caused me to be rear ended were it not for evasive action of the car behind me veering onto the shoulder. I can turn it off when I drive the car but it always comes back on when I start the car. I am undecided about liability as well if I must permit this defective system to run or whether I am protected legally by turning it off. It is such a hassle to constantly turn it off each time I start the car so I just let the car do it's thing most of the time thinking I might be better legally protected with it on than with it off.

I came out to my vehicle and attempted to start it as usual and the EPB would not disengage and I had to have it towed to the dealer. They had to manually disengage it and told me I needed a new switch. I purchased the switch and that did not fix the problem, all of my warning lights have been on the vehicle ever since due to error code "PARK BRAKE MALFUNCTION" i cannot use my parking brake and all of my other ADAS safety features are disabled as a result of this, ABS light, PCS, including Cruise Control, Lane Departure, etc are ALL disabled due to this EPB Malfunction.

1. Driving on the highway with adaptive cruise control feels like taming a wild horse. Pulls side to side, even after alignment and total check up from Toyota. 2. Engine Maintenace required now warning light. This came on at 106,458 miles on Toyota Camry 21 LE. Randomly turned on. Off when air con was turned off, light came back on when air con was turned on. Took to Toyota dealership, repaired at no cost, Coolant bypass valve circuit short to battery or open, known concern by Toyota. DTC p268115 Confirmed and repaired at no cost, customer care warranty. 3. Headlights full of water, condensation at 70,000 miles. Regular Maintenace each 5k miles, bought extended protection plan for 4k, purchased car brand new in 2021 0 miles. at 70k the headlights I noticed condensation inside the headlights. I thought it would go away, later at 100,000 miles both headlights at the same time started to flicker, then DRL only worked, and turn signals and side markers. LED assembly went out completely dead. DRL then stopped working. Headlight retaining clips pulled away from the body of the car. Completely plastic. Headlight seal is completely worn and is peeling away from the headlight. Toyota just inspected car at 106,000 miles nothing said about the headlights. Now at 114k, Need to replace entire headlight on my own. 1 headlight is 1900 at toyota. must replace entire assembly, since it is a LED module. cracks in top mounting latches, entirely plastic. LED circuit board inside headlight covered in corrosion. Kioto Mexico DM026 is the chip inside the headlight located under the LED module. LED lights last 10-15 years. I didn't know I was supposed to reseal a headlight after 3 years. Toyota never told me this, not in the manual either. My headlights are done for. it costs 3000-4000 for OEM. No help from Toyota so far. Quaity issue with LED headlight unit on both sides. Plastic housing falling apart, cracking, clips snapped and breaking, no accidents. others have this issue

The vehicle is experiencing multiple active safety system failures, severely impacting driver control and passenger protection. The most critical issue is a persistent SRS airbag malfunction warning, along with the system failing to detect that the seatbelt is buckled, even when properly latched. This disables key safety systems such as airbags and seatbelt pretensioners. The vehicle also suffers from delayed or weak braking response, despite having adequate brake pad wear. This is especially dangerous in stop-and-go traffic or emergency braking scenarios. In addition, the adaptive cruise control system intermittently disengages or fails to maintain distance, and the brake hold feature does not reliably hold the vehicle when stopped, causing rollback or unintended movement. These issues are consistent with known failure conditions already documented in the following recalls: – the federal safety agency Recall 21V‑890 – Brake booster vacuum pump failure – the federal safety agency Recall 19V567000 – Occupant Classification System calibration error However, Toyota has refused to acknowledge these defects in this case because the vehicle does not fall under the original recall VIN ranges. This creates a serious safety concern, as the same defective behavior exists outside the recalled population, and is being left unaddressed. This not only places me at risk of airbag and braking failure, but puts other drivers and pedestrians at great danger due to the potential for system failure during high-risk moments such as highway driving, stoplight braking, or crash avoidance maneuvers. A broader investigation into the root cause and expansion of the affected VIN scope is urgently needed before serious injury or loss of life occurs

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.
