Selected complaints filed with NHTSA by 2019 Toyota Camry owners, lightly cleaned up (personal details are redacted by NHTSA).
While traveling at interstate speeds (about 68 MPH) a vehicle in front of me (about 6 car lengths ahead) hit a pickup truck. I hit the brakes and then my car's auto braking system was activated (displaying on the dashboard) but it did not feel like my car was slowing down. I then proceeded to push the break all the way to the floorboard and my car did not slow down causing me to hit the vehicle in front of me. It felt like the auto-breaking system was preventing me from applying full braking power. When I pushed the break petal to the floor it felt like I was pushing on air. There was no resistance on the petal as there normally would be. There were no skid marks on the road and after the impact, my vehicle would not move. I had to put the car in park and then back into drive to move off the road.
on 10/29/2021 my daughter was a passenger in her car and was involved in a rear end collision @ approximately 65-70 MPH upon collision with a Toyota Rav4. The Air Bags DID NOT deploy, The seat belt allowed her forward with her breast catching most of the impact, and the front camera system that should have detected the stopped Rav 4 did not alert. We had no error codes nor lights on this car prior and were not aware of any potential recalls. This is a complete failure of a car and safety systems that should have protected her. The entire reason this car was bought WAS to protect her and it completely and utterly failed. She is now in the ER with a broken sternum and currently being evaluated to see if any other vessel damage. …
this afternoon we had 3 safety incidents in a row as we were driving from Austin to San Antonio. Our Camry suddenly lost power while we were on the highway, driving 70 miles an hour, when multiple warning lights came up and the car information screen said "secondary collision brake system malfunction, visit your dealer" when this occurred the car suddenly lost power and decelerated. We had to pull over and find a safe spot to park. Doing so was dangerous because the car was barely moving forward. for the first incident, we turned the car off and we let it sit for 5 minutes. when we turned the car back on, the error code disappeared. About 25 minutes later the same thing happened at highway speed. We parked, turned the car off, disconnected the battery and waited 5 minutes, on restarting the error code disappeared. After another 25 minutes on I-35 the car did it again. …
VEHICLE STALLS AT HIGHER SPEEDS ON THE FREEWAY This problem happened 1 time on 7/22/23, 1 time on 7/23/23, and 5 times between 7/29/23 and 7/31/23 when traveling between Las Vegas and Los Angeles. Symptoms (this repeats every time) 1.High speed (freeway speeds) car stalls, loses power and begins slowing. This is very dangerous in heavy traffic and could have very easily caused an accident! 2.Pumping the gas pedal brings the engine power back within 3-10 seconds and the car picks up speed again. 3.The MIL check engine comes on and the instrument panel rotates through malfunction alerts from ICS, LDA, parking brake, secondary collision brake system, etc. and continues cycling through the alerts until the engine is turned off. 4.When restarting right away, the malfunction alerts and MIL remain. 5.After the car has been off for at least 30 minutes, sometimes the warnings and MIL reset. …
1st time this happened I turned car on around 4am after work and numerous alerts came on (LDA,CHECK ENGINE LIGHT,PRE-COLLISION SYSTEM,PARKING BRAKE MALFUNCTION,SECONDARY COLLISION BRAKE SYSTEM).I Kept turning car on and off but still alerts light up and not allow me to drive due to brakes on. Had to disconnect battery then connect and alerts were gone. 2nd time I was driving and all sensor lights came up again. Locked up my brakes and luckily no cars near by that could have hit me. Took video of the issues when happened. Also on my screen the messages appear of what was malfunctioning. I am scheduling appointment for issue to be checked. But have had other people state same issue happened to them and decided to report issue. Will see if dealer finds issue, even though others people with same issues have not got a resolved issue from dealers. …
When driving home I was doing about 25 mph when my car stalled and 5 or 6 display lights came on. ( secondary collision brake system malfunction, check engine, charging system malfunction, Lda malfunction and engine stopped steering power low.) so I costed into the nearest parking lot blocking an entrance to the facility, so I wouldn't be blocking traffic on a busy 2 lane road at lunch time. So I then put car In park and shut it off and waited. I tried starting my car and it started but raved up and shut off. So I turned key off and waited 10 minutes. I tried 2 more times waiting 5 minutes longer each time. As I'm writing this I'm waiting for tow truck cause now my car won't start at all. But I had someone bring an obd tool and P2119,2111, codes showed up.
1. ABS TRACTION control on, PCS system activated, Secondary brake collision activated and will be available upon inspection. 2. happened mid street with cars in traffic and my daughter in the back seat 3. They are stating transmission but do not want to check ABS system faults. Car was new off the lot unsure why this problem got triggered. I went to Toyota Alhambra and Longo Toyota they do not want to address C codes this is a safety defect that needs to be brought up 4. Will be filing with corporate but wanted to address this issue as this is not the only Toyota with this issue. 5.UKNOWN from my acknowledgement there were no warnings before this happened. Toyota is assuming it is transmission refuses to check ABS system and address C codes
While driving, the vehicle experiences unintended braking and refusal to accelerate. ABS, traction control, pre-collision system, and secondary collision brake warnings illuminate. Toyota dealer diagnostics documented ABS and brake system fault codes C1201 and C1A50. The vehicle also produces a loud whining/buzzing noise from the brake actuator area while stationary. Dealers have recommended transmission replacement despite active ABS/PCS fault codes and safety system involvement. The condition temporarily resets after battery disconnect but returns. This presents a safety risk due to unintended braking and loss of vehicle control. When this happened I was in the street with my daughter in the back we could have got injured.
The car randomly slams on the brakes even when you aren't near anything. Yes it's available for inspection. The safety problem is you could be rear ended at any time when this occurs. My husband was driving on the freeway at high speeds when it happened one time. The other incidents happened to me thankfully at a slower speed but while moving on the road. Also while pulling out or into parking spots. I know it is a safety feature so you don't hit things but I know how to drive and when I can back up safely without it slamming the brakes on. It has not been inspected and there were no warning lights indicating something was wrong.
Toyota camry began shifting rough and jerking when accelerating between 2nd and 3rd gear. Next there was an audible whine and rumble while the car was driving. This occured for approximately 1 week with no indicator lights. On January 1st, there was a total transmission failure and failure of automatic break system and the camry lost power when accelerating. The vehicle only had 64,000 miles and was outside of warranty.
