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. But it is NOT A RECALL. WHY IS THAT? IT IS CLEARLY AN ERROR ON THEIR PART! CAN YOU EXPLAIN PLEASE?

I brought my vehicle into Chevrolet due to my vehicle locking down and thinking the vehicle is being stolen. They told me that the side module malfunctions due to rain and weather conditions. 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 the federal safety agency 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 SBZA sensing module has failed on this vehicle. First failure was replaced under factory warranty, second failure was replaced under special coverage N172097060, third failure was replaced out-of-pocket. Contacted General Motors/Chevrolet, and they are not interested in providing continued coverage of the issue, which is a known issue, and likely a design defect, as the design was changed for later model years.

Complete loss of power assist steering resulting in difficulty in steering the vehicle at any speed. DIC messages indicate: loss of power steering, drive with caution, service traction control, and service ABS. ABS and traction control warning lights remain on and illuminated while driving. These indicators occur each time the vehicle is restarted. This problem originally started about two and a half months ago, and the power steering loss, for a while, was intermittent until recently. The vehicle has not been inspected been inspected by mechanics to date. I have researched hundreds of Impalas online with the same problem with a majority of them remaining unresolved and no manufacturer recall being issued. The vehicle mileage is currently 31, 104 miles and is not driven often because of the problem and the fact that I own two other vehicles.

The blind spot warning system stopped working, and yes it is available for inspection upon request. I have heard this leads to further electrical problems and am worried this may compromise my safety if not dealt with. The problem has not been confirmed by a dealer. The component has not been inspected. There was a warning that popped up stating “service side detection system” that appeared randomly on my drive home the other day. I had not hit anything or done anything to the car that might have caused this.

The Side Detection System failed. Both rare modules are shorted. The defective module drain out the battery, causing engine start failure. And the defective module may cause fire. I have one side of the modules repaired in three years ago. Now both sides are failed. I had two jump start in the recent month. Every time I start the engine, warning for service of Side Detection System shows up.
