Adaptive Cruise Control Problems of Toyota RAV4

I was heading south on I-495 (massachusetts) in right lane at just under 65 mph. I had just passed an entrance ramp and overpass. A car was entering i495 on my right and coming up to speed. The car entered my lane from his entrance ramp to the right most lane in front of me. The car was about 20 feet in front of me. The entering car's speed was was greater than mine. When the second the car left the entrance ramp and pulled into my lane about 20-30 feet in front of me, my brakes slammed on, causing me and my passenger to lurch forward. My seat belts protected me and my passenger from harm, but it scared the **** out of us. This kind of nonsense of so-called "safety features" has to stop. Its bad enough that I have to put up with a car that stalls out when the car stops, even for a second, but what happened above is unacceptable as a "safety feature. " I could have easily reacted by jerking the steering wheel to the right and gone off the road at full speed, fast enough to roll the car causing considerable harm to life.

The high voltage floor underwire harness and rear traction motor cable corroded. This caused many if the vehicles sensors to fail completely including the tire pressure monitor system, adaptive cruise, collision avoidance, and more. Toyota is aware of this problem and attempted to do a silent warranty extension. This is a safety hazard and all of the known vehicles affected should be recalled!.

On 2 occasions while driving on a flat straight interstate highway using the adaptive cruise control, with no vehicle in front of me, the vehicle has suddenly tried to stop. Pressing the cancel button for the adaptive cruise control would not shut the system off. When the accelerator was depressed to attempt to get the car moving forward, it continued to try to stop the vehicle even harder. Pressing the brake pedal also did not disengage the adaptive cruise control. I had to allow the vehicle to creep off the highway, then shutdown the vehicle and then restart to resume driving.

The wiring harness to the lithium battery is corroded, and it is unregulated. My repair shop said the car is unsafe to drive because of the amount of unregulated electricity in the battery. Also, the cruise control doesn't work. My repair shop says this is happening to other vehicles. Parts and labor total almost $7,000.

I was stopped at a red light. When the light turned green and I pressed the gas, the engine sputtered and almost shut off. Just before I came to a stop, the engine revved up and the vehicle accelerated. The uneven acceleration is concerning. I recently replaced the gas cap and serviced the fuel system, which leads me to believe there is a defect with the engine. Later in the day, the check engine light went on and awd system, cruise control, and lane assist were disabled.

Cruise control suddenly quit working, alarms for hybrid system malfunction, cruise control malfunction. This is a known issue for Toyota, high voltage leaking out because of a corroded ground. This repair is going to cost around $7,000 out of pocket. . My car is 3 years old.

In line at a restaurant drive through around 2pm, raining, wipers on. Engine cut off and power steering low message displayed. Car would not restart for several (30 minutes) cause unknown. All battery, starter, alternator test came back fine.

While traveling on highway with adaptive cruise control engaged and maximum following distance selected, adaptive cruise control applies excessive braking force than necessary when vehicle in front exits highway. Safety concern because following vehicles must abruptly apply brakes. Internet search reveals numerous, similar complaints. We were almost rear-ended on the highway. This feature is great, but needs attention for safety reasons.

Front miliwave sensor malfunction (radar senor) required replacement immediately due to safety concerns by dealer. Because it could cause unintentional braking. Also because this system is connected to other safety features. I only purchased this car recently from a third party car dealer less than a year ago and this problem only went on for less than a week before service. And the only warning was that the adaptive cruise control stopped working.

While traveling on highway with adaptive cruise control engaged and maximum following distance selected, adaptive cruise control applies excessive braking force than necessary when vehicle in front exits highway. Safety concern because following vehicles must abruptly apply brakes. Dealership or police have not inspected vehicle. No visual or audio warnings. Internet search reveals numerous, similar complaints.

The cruise control has issues. On 3 long rides so far, I have experienced that it suddenly loses speed and gives the message radar ready now. Furtunately I was maintaining very safe driving distance with other cars on the highway, which has helped me accelerate in time to continue driving and avoid collision. I dont know of any pattern which triggers this. This could lead to a serious problem if it fails in a tricky spot on highway. I am afraid to use it as its not 100 percent reliable.

1. For two different occasions the high beams wouldn't turn on at night on a dark road and rainy day. Took the vehicle to Toyota but mechanic reported that he couldn't reproduce event. I had to drive very slowly with normal lights as I could. 2. For two different occasions the vehicle wouldn't start I almost had the vehicle towed but using the Toyota app and the key fob was able to remote start and then start the vehicle. I can't imagine what would have happened if the car turned off in the middle of an intersection and wouldn't turn on. 3. The adaptive cruise control has a glitch that I have told Toyota. If you're going over 30 mph and the vehicle in front of you has been in a complete stop for a while, the car may not stop you have to manually stop or crash. This could be extremely dangerous.

While using cruse control. It did not slow the vehicle. I could not turn it off. The brakes would not work. I ran thru an intersection against the light. Bounced over the median. I turned off the ignition, still coasted about 1/2 mile. Finally I jamed the gear shift lever into park. Toyota has the vehicle for inspection and reading of the black box.

I bumped the car in front of me when starting from a red light at an intersection. Impact speed was less than 3 mph. The damage from this impact resulted in repair cost of almost $4,200. This is outrageous and an example of poor design on the part of Toyota. It is my understanding that the standards require vehicles to absorb up to 5 mph frontal impact with no damage. Had I known this vehicle was so poorly protected I would have chosen to purchase something else.

The Toyota adaptive cruise control keeps a safe distance to the vehicle in front, slowing and accelerating properly to keep a set distance even down to a full stop. However, when traveling at any speed and another car enters my lane immediately in front of my vehicle the system does not recognize the new vehicle and how close it is to the front of my vehicle. It does not slow at all even if the distance to the intruder is only a car length or less. I have to manually brake quickly to prevent following to close and causing a possible rear end collision. This happens every time a car squeezes in from of me with the adaptive cruse on and is very repeatable. I've experienced it in another new rav 4 too. This has been repeatably going on since the vehicle was purchased new on Jan, 2020.

Does not maintain cruse control speed that I set when traffic becomes heavier around the car for example…. Cruise control stops working and car slows down as vehicles are passing my car, or are driving in front of me or in back of me. It does not like traffic near by. If there’s no traffic it works and maintains the set speed.

With rain and snow the sensor start beeping and warning of objects in front of the vehicle when there are nothing. Driving in snow gets the sensors blocked and you cant use the cruise control.
