A week prior to this incident, the 2020 RAV4 was taken to Toyota for its maintenance check where everything was checked, replaced and changed. However, the last two days an incessant message keeps popping up on the dash stating “engine maintenance required… Visit your dealer” taking up the entirety of the middle screen inhibiting my ability from seeing my speed, mileage, distance to empty , time, lane assist and other car information that I normally rely on. I have pressed the “arrow back” or “back” button numerous times but three seconds later the message pops again inhibiting me from being able to use necessary car controls to stay safe. The engine on the 2020 RAV4 needs to be recalled as my car only has 55,000 miles on it. I have talked to numerous professionals within the motor industry in which they state these engines have lower stability and life expectancy than PREVIOUS engines used in older RAV4 models. Not only the engine, but the messaging system within the RAV4 needs to be fixed immediately as the communication of maintenance WHILE driving is a hazard. If I cannot look at texts to even just simply read it, why is there is message bright and in the middle of my dashboard popping every 3 seconds with a bright red triangle stating that I need “engine maintenance required,visit a dealer”. This is a safety issue and one in which almost nearly cost me my life.

Ongoing problem with an intermittent steering issue. The problem is that this is an intermittent issue and hard to get to dealer during time of concern, and while they could troubleshoot the issue before the issue fixes itself. The concern ALWAYS happens upon starting vehicle. Never happens when you are already going and issue is not present. Steering wheel will pull right, or left, upon start up, and then at some point it fixes itself and problem is no longer an issue. Could happen at any time upon start up, cold or hot weather, fresh start, or going back out after having been on road already, just no rhyme or reason for it. The safety issue is that when turning, when it is pulling, is that it pulls you towards the curb/shoulder, or towards oncoming traffic. Additionally, it will also not return the wheel after a turn, so if it was pulling left, and you are turning left for example, you have to manually get that wheel back or it'll just keep going left. I've experimented with turning off lane keep assist, lane centering (cruise control), put it in different modes like trail, sport, etc. and even stopped on the shoulder, and tried to re-start the vehicle. Nothing can stop it consistently. And it fixes itself within a 10 minute period. I have checked the AWD monitor screen to see if a wheel is pulling harder than the others based on the display of power going to wheels, no luck. It has been doing this since day one. Not every trip. Not even every week. Sometimes it could happen 5x in a week, and sometimes it could be 2 weeks before it happens again and then again in another couple of weeks. Not the road either. Must be paying attention when starting out because it could happen on any trip, during a trip if stopping and re-starting vehicle while on a trip, etc. because it can/will pull you. I have a video, albeit hard to really see much but shows car pulling. Also note this is NOT a torque steer because it could happen on acceleration OR not.

A different problem that involves steering is when using speed control (cruise control). I only have attempted this while on the PA Turnpike at faster speeds, or a highway with a higher speed limit, but when engaging speed control with lane centering assistance, vehicle will sometimes pull you too close to the left side of your lane. In some cases, it will almost appear to others you are drunk as it is working to keep you centered in your lane, but at times it will just pull you to the left side of your lane, so close to others that traffic will beep and I'll want to poop my pants, because it harder to pull back to center when this is doing the steering for you in cruise control mode. Have turned off lane center assist and the speed control works fine, including slowing you down as traffic slows. But with lane center assist on, and using cruise control, this is when erratic behavior exists. Dealer could not duplicate the issue - would require taking this on a fast moving highway, like the PA turnpike, and hope it happens while out on that trip. Does not always do it, and have to been able to figure out why it does it (I.E. double yellow line vs. white intermittent line). When it happens, it puts you too close to traffic next to you and could cause other vehicles to either impact with you or make them swerve out of the way thinking you are coming into their lane. Very serious when it happens, moving at high rate of speed, and lane centering when using speed control is very strong and harder to override vs. the small bump it gives you when not using speed control and too close to the shoulder for example. That lane correction works well, albeit a bit weak to correct. Has happened since new, August 2020. And continues to happen sporadically.

I have had a number of instances where my vehicle's lane keep assist will randomly jerk me out of my lane. In sept 2020 I experienced a significant event of this happening when I was driving in the right lane of an interstate and the vehicle jerked right suddenly, pulling the vehicle into the right shoulder and almost drove me off the interstate. Another significant instance happened on 1/23/2021. I was driving northbound on I-44 and I was in the middle of 3 lanes. My vehicle suddenly jerked the vehicle to the left into the left lane of traffic. Luckily, the vehicle next to me swerved onto the shoulder thinking I was going to hit them. There have been other regular incidents of this happening, but not as severe as these two.*dt*dt the consumer stated while driving on I-44, the vehicle suddenly jerked to the left towards traffic. The cruise control was not activated. The consumer stated the repair technicians were able dulicate the failure but, unable to repair it.

Toyota tells me that the lane departure system (lda) and the lane tracing system (lta) are independent by design. This creates an unsafe driving environment and has the potential to cause accidents. I have about 4700 miles on my car and many miles of driving with the lda & lta engaged. I had positive control of the steering wheel at all times in the incidents described below. While driving down the road the lta constantly makes corrections to the relative position of the car in the traffic lane. It regularly tries to steer you out of your lane. Usually, when the lta is steering the vehicle out of the lane, the lda signals. The lta does not make a correction despite the lda sounding. If the lta/lda communicated, rather than being separate modules, the lda would tell the lta it was about to steer the car out of the lane and make the correction. Instead, the lta steers the car out of the lane and the lda tells you that you left the lane or will leave the lane. When I drove 40 plus miles to the dealer, I told him that I felt as if I had wrestled the vehicle the entire way. The service manager drove the vehicle and experienced the conditions I am describing. He told me that toyota told him the vehicle was functioning as designed. I also called toyota USA and was told the systems are independent and functioning as designed. I told the dealer and toyota USA that the systems are a safety hazard. As an independent system the lta creates a hazardous driving condition. It is trying to steer you out of your lane, and if you don't maintain strong pressure on the steering wheel, you will leave your lane. That is especially true if you if drive by an exit lane. On an exit lane to the right, even though there is a lane marking to the left of the vehicle, it make a sharp pull toward the right,
