2020 Toyota RAV4

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.

ON FEBRUARY 6, 2021 IN ATLANTA GA, THE VEHICLE, WHILE IN MOTION AT AROUND 30MPH, DISPLAYED A 'HYBRID SYSTEM MALFUNCTION' WARNING AND BEGAN BEEPING AND TREMBLING. THE WARNING SAID THAT THE CAR MUST BE STOPPED WITHIN 0.9 MILES BUT LASTED FAR LESS THAN THAT, FULLY LOSING ANY EFFECT OF THE ACCELERATOR PEDAL MID-TRAFFIC. THE VEHICLE COASTED INTO A PARKING LOT ON MOMENTUM AND WAS STOPPED WITH A FINAL WARNING THAT BRAKING POWER WAS REDUCED. HAD THIS VERY SITUATION OCCURRED ON AN INTERSTATE, IT EASILY COULD HAVE BEEN FATAL TO MY WIFE, WHO WAS DRIVING AT THE TIME, AND TO OUR UNBORN CHILD. THE VEHICLE IS 9 MONTHS OLD, WAS PURCHASED NEW, AND HAS AROUND 15,000 MILES.

TRIED TO SET RADAR CONTROLLED CRUISE CONTROL FOR THE FIRST TIME ON A WORK TRIP TO MICHIGAN AT 70 MPH. THE STEERING WHEEL IMMEDIATELY TURNED TO THE LEFT AND TOOK CONSIDERABLE PRESSURE TO KEEP VEHICLE STRAIGHT. TOOK SUV IN TO SHOP AND THEY SAID THE RADAR CONTROLLED ADAPTIVE CRUISE CONTROL WAS WORKING FINE AND THEY COULD NOT DUPLICATE PROBLEM. THIS WEEK TOOK ANOTHER WORK TRIP TO MICHIGAN AND THE SAME PROBLEM HAPPENED ABOUT 20 TIMES WHILE TRYING TO SET CRUISE CONTROL AT 70 MPH. WHEN I DISABLED THE RADAR CRUISE CONTROL THE PROBLEM VANISHED BUT THE SUV WOULD NOT DETECT TRAFFIC IN FRONT OF IT AND OF COURSE WOULD NOT SLOW DOWN. WILL TRY TO VIDEO THIS PROBLEM AND TAKE SUV BACK TO SHOP FOR A FIX.

TL* THE CONTACT OWNS A 2020 TOYOTA RAV4. THE CONTACT STATED THAT THE RADAR ENHANCED CRUISE CONTROL FAILED TO OPERATE WHILE DRIVING AT VARIOUS SPEEDS WITHOUT WARNING. THE CONTACT STATED THAT WHEN A VEHICLE PULLED IN FRONT OF THE VEHICLE, THE VEHICLE SLOWED DOWN HOWEVER, THE BRAKE LIGHT FAILED TO ILLUMINATE. THE VEHICLE WAS TAKEN TO TWIN CITY TOYOTA (301 AUTUMN RIDGE DR, HERCULANEUM, MO 63048) HOWEVER, THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 59. *BF*JB
