There are 2 owner-reported powertrain & transmission complaints for the 2010 Lexus GXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My 4 LO light is constantly flashing, and I lose power when trying to accelerate. 1.Loss of Traction Control: If the 4WD system fails while engaged, it could lead to a sudden loss of traction. This can be particularly dangerous in conditions where 4WD is necessary, such as on slippery roads, steep inclines, or off-road situations. 2.Unexpected Vehicle Behavior: A malfunction in the 4WD system could lead to unpredictable vehicle behavior. For example, if the vehicle unexpectedly shifts into or out of 4Lo mode, it could disrupt the driver's control over the vehicle. 3.Increased Wear and Damage: Operating the vehicle with a malfunctioning 4WD system can lead to increased wear or damage to the drivetrain. Over time, this can result in more significant failures, potentially leading to unsafe driving conditions. 4.Difficulty in Handling: If the vehicle is stuck in 4Lo mode, it might become difficult to drive at higher speeds. The 4Lo mode is designed for low-speed, high-torque scenarios, and driving in this mode on regular roads can affect handling and control. 5.Increased Risk in Emergency Maneuvers: Should an emergency maneuver be necessary (like sudden braking or evasive steering), a malfunctioning 4WD system could impede the vehicle's response, increasing the risk of an accident.
2010 LEXUS GX460. AFTER DRIVING IN REVERSE, AND PUTTING THE VEHICLE INTO "DRIVE" THE VEHICLE MAY STALL IF YOU APPLY THE GAS PEDAL TOO QUICKLY. I'VE NEVER HAD THIS PROBLEM WITH ANY OTHER VEHICLE. I JUST BROUGHT IT TO LEXUS FOR THIS PROBLEM AND THEY SAID IT WAS NORMAL. THIS CONDITION ALMOST CAUSED ME A SERIOUS ACCIDENT. I HAD TO BACK INTO A STREET WHICH HAD POOR VISIBILITY DUE TO HILLS. AFTER BACKING UP I NOTICED ANOTHER CAR COMING OVER THE HILL RIGHT BEHIND ME, SO I QUICKLY PUT THE CAR IN DRIVE AND APPLIED THE GAS TO AVOID AN ACCIDENT, AND MY VEHICLE STALLED AND THE OTHER CAR HAD TO GO INTO THE OTHER LANE TO AVOID A COLLISION. I NOTICE MY CAR ALSO HESITATES AND ALMOST STALLS EVERY TIME I BACK OUT OF MY DRIVEWAY AND START TO MOVE FORWARD. *TR
