“Odometer Fraud. The contact purchased a 2015 Chevrolet Impala. The contact stated that there was a mileage discrepancy after the purchase. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 182,412. It was later discovered upon checking the Title that the mileage was 186,199.”
“I have always kept my Impala in my garage until recently I started keeping my grandson a few days a week. When I am at that home my car is parked in a driveway open to the elements. About a month after starting I notice that my car started having what I would describe as an electronic issue. The seat belt alarm would go off without me ever touching my seat belt. I have also had to replace my tail lights in my vehicle twice since this started. Then when I packed for a trip yesterday I noticed an awful smell in my trunk. I could not find the source, so I took everything out of my trunk and opened the spare tire compartment which was completely filled with water! I found a Product Bulletin on this. Chevrolet #14047.

He then says the part is on back order for possibly 12 months or greater! I drive for my job and blinkers and everything safety shuts down to make It unsafe to sell or be driven. I am at a loss to know how to proceed. I will be contacting the minnesota Attorney General as well. Help please”
“Side Blind Zone Alert (SZBA) system continues to be an issue with this vehicle. Sensing module(s) on inner left or right side of bumper cover fail due to water intrusion. When sensing module fails, "Service Side Detection System" message will appear on driver information center on instrument cluster. General Motors has previously issued a special coverage "N172097060", which is available on NHTSA website. As indicated in the special coverage document, if the issue is ignored, "the condition could result in the corruption of LS GMLAN that may result in the loss of some driver interface functions such as cluster, infotainment, displays, chime, and passenger presence detection (passenger airbag could be suppressed). Within approximately 30 days of the "Service Side Detection System" message, while driving, instrument cluster speedometer and tachometer went dead, and airbag warning system notification, anti-theft system, tire pressure monitoring system all illuminated. In addition to no speedometer reading, vehicle ignition/security interlock was causing vehicle to run rough. Vehicle would not immediately restart after shutting vehicle off. This is the 4th time a…”
“The contact owns a 2015 Chevrolet Impala. The contact stated that while her mother was starting the vehicle, there was an abnormal plastic burning odor and smoke entering the vehicle through the air vents on the center console. The contact stated that a neighbor assisted and became aware that the sun visor vanity mirror on the driver's side was melted off the visor. There was no fire. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 130,733.”
“GM has a know issue with the side detection system and refuses to do anything about it even after there service bulletin expired. When this fail it can cause other issues with the dashboard system failure and more. In this case the system would never shutdown draining the battery.”
