2013 GMC Acadia Lane departure Problems

“The service side detection system has appeared in the dic due to water intrusion in the sensors. They were originally replaced per the tsb16-na-178 in april of 2019. The issue has since re-occurred 2/18/21 while driving, which jeopardizes my safety. I also understand that this may lead to additional electrical issues and may cause the vehicle to enter limp mode.”

“Driver side detection blind zone, intermittently comes on, then after several days just stopped working, I replace the blind zone module located under rear bumper, it worked fine for a week and then shows service side detection system, and both sides blind lights on mirrors don't work, all this happened while the vehicle is running”

“On 02/10/2022 my side warning detection monitors are both activated/lit up intrmittently while parked or driving indicating faulty operation and therefore replacement. The vehicle has around 120K miles so out of any warranty. But this will be the third or fourth time ( not original ow er so dealer has records) that this has happened. Last time in December 2020 I had an extended warranty that covered the passenger module but was not the improved module with some type of casing to address the corrosion causing the failures as they wanted an extra $3-400 for that part. …”

“The original side detection system is not an enclosed system. Allowing water, snow, sleet, and salt can penetrate the system. Once, there is penetration and corrosion in the system it effects the entire automobile's electrical system and instrument cluster. Causing the vehicle to come to a complete halt.”
