CVT Transmission Judder and Slippage
The CVT exhibits shuddering during acceleration, rubber-band effect throttle response, and occasional slippage at highway speeds. Some owners report a delay between pressing the accelerator and the vehicle responding, typical of CVT belt wear.
CVT fluid replacement with NS-3 specification fluid and TCM reprogramming. TSB NTB14-012G provides CVT service procedures. If slippage is severe, the CVT assembly may require replacement.
Est. Cost: $200 - $5,000Automatic Emergency Braking False Warnings
The forward collision warning system issues false alerts and the AEB applies brakes when no obstacle is present. The issue is more prevalent in rain, near guardrails, and when approaching vehicles in adjacent lanes.
Front radar sensor recalibration and AEB system software update at the dealer. Ensure the sensor window on the front grille is clean and undamaged. Sensor replacement if recalibration does not resolve the issue.
Est. Cost: $0 - $600Brake Switch Misadjustment Causing DTC Codes
The stop lamp switch and/or brake pedal position switch may go out of adjustment, causing DTC C1142 and/or C1116 to store. This can affect cruise control, AEB function, and cause the brake lights to remain on or not illuminate properly.
TSB provides a procedure for brake switch adjustment and recalibration. The stop lamp switch position is adjusted and the system is reset. This is a straightforward service-bay repair.
Est. Cost: $100 - $250Infotainment Screen Lag and Connectivity Loss
The touchscreen infotainment system experiences significant lag when navigating menus, frequent Bluetooth disconnections, and Apple CarPlay/Android Auto connection drops. The system may also freeze and require a vehicle restart.
Update to the latest infotainment software version at the dealer. Performing a factory reset and re-pairing all devices. Replacing the USB cable with an OEM-approved cable for CarPlay/Android Auto.
Est. Cost: $0 - $200Steering Column Nut Loosening and Clunking
A clunking or creaking noise emanates from the steering column while turning or driving over bumps. The noise is caused by the steering column nut loosening from vibration and road impacts, creating play in the column assembly.
Retorquing the steering column nut to specification and applying thread-locking compound. If the nut or column components are worn, replacement of the affected parts may be necessary.
Est. Cost: $100 - $400
