2017 CHEVROLET VOLT Visibilitywiper Problems

The high-voltage heater control module (also known as the PTC coolant heater / K10 heater module) has failed. This component controls cabin heat and windshield defrost when the vehicle operates in electric mode. The authorized Chevrolet dealer diagnosed the issue, confirmed the failure, and attempted to order the correct GM part. GM informed the dealer that the part is no longer manufactured or available through GM channels. As a result, there is currently no GM-approved repair path. This failure prevents the vehicle from providing windshield defrost while operating in EV mode, which is required for safe winter visibility. I live in New Hampshire, where winter temperatures routinely require functioning cabin heat and defrost for safe operation and compliance with state visibility laws. Because this is a high-voltage thermal management component, there is no safe aftermarket repair option. The inability to obtain an OEM replacement part for a safety-related system prevents...

P1E00 error code resulted in the propulsion system being reduced and climate controls turned off. My wife, driving at the time in a thunderstorm, lost the ability to drive the speed of traffic and also her windshield completely fogging up where she could not see. She could have been killed in this scenario in a number of ways. Took it to the dealer where GM apparently has no spare parts available for months??? Parts at fault are related to the EGR valve and cooler. CEL light came on and off for a few days prior. Failed to be able to pull the error code because it would go off.

WHEN THE ENGINE IS RUNNING AND I AM DRIVING ON ANY STREET OR HIGHWAY IF I SHUT OFF ANY COMPONENT OFF THE HVAC SYSTEM, THE VEHICLE WILL GET VERY DAMP INSIDE. ON RAINY, FOGGY, OR COLD CONDITIONS ALL THE WINDOWS WILL FOG IN 30 SECONDS TO THE POINT I CANNOT SEE. IT WILL TAKE SOME TIME TO CLEAR IF I TURN IT BACK ON. THERE IS SOME DEGREE OF DAMP MUSTY FEELING IN MY CAR ANY TIME I TURN THE SYSTEM ON AS WELL. I AM AFRAID IT WILL START GROWING MOLD. I CANNOT GET THE DEALER TO WORK ON IT UNDER WARRANTEE. I HAVE AN EXTENDED WARRANTEE. THIS PROBLEM HAS BEEN PRESENT SINCE THE CAR WAS NEW. IT HAPPENS STILL.

THE HMI (HUMAN MACHINE INTERFACE) MODULE, A PRIMARY COMPONENT OF THE VEHICLE'S IN-CABIN COMPUTER SYSTEM, CAN FAIL IN A 2017 CHEVROLET VOLT WHILE THE CAR IS AT REST OR IN MOTION RESULTING IN THE INABILITY TO ACCESS OR USE THE VEHICLE'S INSTALLED BACK-UP CAMERA. THE 2017 CHEVROLET VOLT HAS VERY POOR REAR VISIBILITY WITHOUT A BACK-UP CAMERA. IF THE DRIVER IS UNABLE TO SEE CLEARLY BEHIND THE VEHICLE, AN ACCIDENT IS MORE LIKELY TO OCCUR.
