2015 CHEVROLET IMPALA Complaints

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 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.

I was driving my 2015 Chevy Impala on the highway and my steering gave out into a curve. I got deeply afraid when the steering froze up on me, specially at 50 into a 40 mile rated speed. I say this because I wasn't aware that GM vehicles stop putting power steering pumps in their cars nice the late 2000's. I called onstar and inform them to the problem I was having with the car. I was able to get it to a safe spot. And the vehicle towed a dealership for servicing. I was told it was software malfunction that needed to be updated. Costing me $775, which my insurance company under CarCare wouldn't cover. I canceled them quickly. The car steered fine after getting it back. Then the same issue happened again a day later I call the dealership again close to my home, they told me the motor on the steering rack and pinion gave out. And was going to cost, 4100 dollars. I had another insurance company Endurance. They said they'll cover the rack but not the motor to the service department and denied the claim. Out of anger of payments to both insurance companies. The vehicle was traded in for a newer car. Value at 2000 dollars for trade. I'm bringing this to attention because GM is aware of this issue and don't want yo acknowledge this safety issue. Thank God I'm able to stronghold the car and bring it to safe spot. But for others with the Chevy Impala's not so lucky! These vehicles are scary and a dangerous for highway running, after the warning light appears on the dash!

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.
