Side detection system failures. Repaired side detection systems 2 times ( 2017/2018 and again in 2020) both times GM reimbursed for repairs under technical bulletin. Repairs were supposed to be using “redesigned” parts to prevent issue from reoccurring. Side detection system requires service again in February 2023. That is 3 times this failure has occurred in 8 years of owning this car. I have been told not too drive this vehicle with this issue as more serious issues can happen - dashboard failure, engine issues, etc. which can cause serious issues while driving. Even though GM extended the warranty for this, it doesn’t seem fair that I have to continue to pay repairs for a defective system ….. especially when I cannot drive for safety reasons. If this were just cosmetic, not that bad an issue. But this is a safety concern.

Multiple electric concerns...airbag light, park assist, inop camera, and losing communication with BCM(?) Found multiple communication codes for a variety of different modules. Found main source to be from the "side detection modules". Found fuse 62 blown underhood. Inspected side detection modules and found "a lot of corrosion" on both modules and connectors. Needs side detection kit. I purchased the used impala on 12/19/2020 with 63,897 miles. The first time this issue was a concern was on 07/02/2022 at Merit chevrolet (MN). Mileage was at 83144 at that time. Diagnosis ... recommend both rear side detection modules and harness? According to Special coverage adjustment #N172097060 it is known to be subject to "water intrusion"? This problem affects the whole electrical system which includes airbag function. Why does this safety concern have a limited coverage time? According to the "Special Coverage" document, there was an 80000 mile timeline? This appears to be an ongoing issue with this year, make, and model and my feeling is that a "special coverage" is denying the safety problem and putting it on the consumer?

The 2014 Chevy Impala is dangerous. When the rocker arm control valve and related parts fail or the camshaft solenoids and sensors fail the car will drive rough and eventually just cut off in the middle of traffic highway or residential. This is what it did on me, putting me in a very dangerous position. The economic loss is still devastating financially as all 2.5 and 3.6 engines arent covered by GM special warranty but they should be all covered. My VIN number was not included when it should be.

I was driving in a snowstorm and all of the sudden the ABS, Stabilitrak, and power steering went out. I'm frustrated that this is the 2nd electrical safety issue that I have experienced. Both of which have been reported by several drivers and still no recalls!

This car has exactly the same issues as reported in 15V465000 but Chevrolet refuses to acknowledge that this VIN should have been in their recall. The AOS systems in this Impala is improperly calibrated. My child in the front seat could be seriously injured. Chevrolet themselves verified this 2014 Impala has front vented-heated passenger seats. They still refuse to help in any way. This car does not turn the front passenger airbag on and off when it detects (or fails to detect) an adult occupant in that seat.

When pulling up to a stoplight the car would often downshift, surge with power, and nearly overpower the brakes. The car started losing oil from its rear main seal. When I finally had the seal replaced the repair shop found that pieces of the thrust bearing were laying in the oil pan. The engine and transmission had to be removed from the vehicle in order to replace the thrust bearing. They showed me a box full of parts, but I did not keep any.

When getting of the exit from the high way my steering wheel locked up. We were going about 40-50 getting into a slow speed from the highway. I struggled with turning the wheel just to get off of the ramp. And then a sign came up saying service power steering drive with care. It’s showing that my vehicle doesn’t have a recall for this. But this is absolutely not safe at all. I had my 2 infants and 7 year old in the vehicle.

Due to a poor electrical ground connection to the power steering control module, the vehicle has been losing power steering assist during start up and while driving; this requires much greater effort for me to steer the vehicle even at low speeds, and is increasing the risk of a crash for me and my family.

When I drive down the road my blind spot detection sensor goes off and lights up in the passenger mirror. It lights up if there is or is not a vehicle in my blind spot and has made me swerve back because I think there is someone or something in my blind spot. I have looked into this problem and it seems that there can be other issues that stem from this malfunction. I have owned the vehicle since 2019 where I purchased from a certified Chevrolet dealer and was not informed of this problem. This problem started to happen about 8 months ago and I reached out to where I purchased the venicle from with no response back from the salesperson I purchased thru. I don't want to continue to deal with this dealership and not get a return call from them. I have not had any other dealership look at this problem but I really need to find someone that can and will take care of this for me. I don't feel safe sometimes when changing lanes or letting my girlfriend us my vehicle to goto the store, or even take her child to school or sporting events he is involved in. I have done some searching on my own and seen that Chevrolet knows about this issue but I still have not received any information about this problem that has been going on for quite a bit of time.

I have taken it in on several occasions and been told there is no active code. My transmission control module constantly looses communication. Through my research I have found numerous accounts of this part failing and GM not repairing it, nor issuing a safety recall. I took the vehicle in and was told it was a common failure. The failure of this part has put myself and my children in danger, the computer failure causes the car to randomly shift gears while driving jerk violently and completely shut off at times. Currently it is stuck in 1 gear. I am a single parent, I am scared to travel with my children in the car, anywhere including school and medical appointments. This issue happens while driving the vehicle at all speeds including highway speeds. The last time I took it in the dealer stated, the vehicle was not safe to drive they notified my warranty company, which took 2 weeks to look at the vehicle at which time I was told that the fault code was not active but only in the history of the computer and they refused to repair it. Being that this is a known issue by GM I believe a safety recall should be issue before someone is hurt or killed, if they havent been already. The service advisor informed me that they were instructed to clear the codes from my OBD let the car sit and see if the issue returned. This issue has affected multiple GM vehicles yet they refuse to make the repair necessary to make the vehicle safe. questions; 1)TCM fails, yes it is available for inspection. 2) vehicle randomly shifts through gears including park, at all speeds. causing car to jerk violently, shut off or get stuck in 1 gear. It has shut off while traveling at 75 MPH on the high with my children in the car on multiple occasions. 3)yes at covert chevy in hutto, tx. even the service department was scared to drive it. 4) I dont know what the dealer inspected. 5)yes service stabilitrack and power steering and check engine light with code U0101
