2014 Chevrolet Impala Driver assistance Problems

I previously owned a 2011 Buick Regal and now have a 2014 Chevy Impala. Both vehicles have had a Stabilitrack warning come up. Both vehicles experienced the same issue. The car seemed to jerk, lag in speed, cannot accelerate over 40mph. The Regal was diagnosed with an electrical/wiring issue. The Impala was diagnosed with a failed Transmission Control Module. We now have a 2016 Impala and the same issue and warning lights have appeared. That’s 3 vehicles we’ve owned from GMC with the exact same issue. This can’t be a coincidence and should be looked into. There are hundreds, if not thousands, of more consumers on forums experiencing the exact same issue. This should be recalled! Imagine the possibilities of danger this can cause when on the interstate and can’t accelerate over 40mph.

Incident

Side detection system failure. I have had 3 harness replacements on driver side. 2 harness replacements on passenger side, and a module replacement just 2 years ago. This failure causes my instrumentation to shut off, turn signals not work, and shuts off cruise control when in use. I have read outher more extreme cases like engine compartment fires or car shutting off while driving. I believe all these should be considered safety issues. I have owned this vehicle since new.

When at a stop and turning left it makes a grinding noise with hesitation in movement. The ABS and traction control light comes on. When researching this, there are millions of these cars with the same thing. I have taken to 3 mechanics and no one can fix the problem.

The side detection module has just failed out for the second time in under 2 years, 20k miles on my 2014 Impala LTZ. The first time it failed (less than two years ago), the side detection indicator on the mirrors started to go off randomly, and then eventually, I was unable to reliably lock/unlock my car. Eventually, it wouldn't even start/shut off (Push to start), and the entire dash was off even when running. It messed with seemingly the entire car's electrical system, and made it unsafe to drive (imagine if I would've been on the highway and the car shut down, plus I didn't have any gauges at all). As stated, this system (and side detection module specifically), has corroded and gone out again, despite this module supposedly being better sealed. I had a GM dealership replace the entire system with their kit, which was out of their specialty 80k mile warranty for this system, as they realize it is flawed but refuses to recall it. This kit was approximately $1000 installed, and I am again looking at the same price for a flawed system that GM is totally aware of and one that has safety implications and makes the vehicle undrivable.

My blind spot detectors went out, now as a result most of the electrical stuff no longer works. The car powers on and drains the battery randomly and the speedometer doesn’t work. Every light comes on from front camera, abs, and even power steering. I didn’t feel safe taking my kids to school and now I don’t feel I should pay $1,300 out of pocket.

Every year the side sensor goes bad.. This causes vehicle to loose important factors while driving. Headlight go off and on. Speed goes to 0, all codes flashing, gas and ram gone. Car also locks and unlocks randomly along with no heat or air.. This has happened twice even after fuse is pulled while waiting on yet another $1000 repair. This is so very unsafe. Car needs to be removed from roads or side sensor part coverd.

Messages for “service side detection system” and “service rear vision system” appear web vehicle is turned on. Side detection system as well as backup camera are both non functional. GM knows about this issue and had a recall/ warranty repair program. however I was never notified to bring my vehicle in to have this repair done, and now I believe it is past the date that was set to have repairs covered. Will be contacting GM to have these things potentially fixed.

On July 11th 2023 I finalized the purchase of a black 2014 Chevy Impala LT at Premiere Auto Solutions LLC. The beginning of the week of July 22nd I started hearing loud noises coming from back tire area. On approximately July 24th, the engine light came on for small Evaporation leak code. Returned back to Premiere Auto and spoke with worker\dealer about situation with the car. Was told by this person after a test drive with him that the back tire noises are normal due to the braking system, and he cleared the engine code from dash panel. Within the next week, back tire noise got worse and engine light came back on along with message to service front camera\side detection system. Car diagnosed by two mechanics for replacement of back rotors\brakes and Evaporation purge valve. Attempted to contact Premiere Auto to no avail. On August 4th the vehicle suffered an electrical failure with total loss of power while driving. On August 7th the car was towed to Bob Johnson Chevrolet at 1271 W. Ridge Rd. Rochester, NY, 14615. The car is still there diagnosed with a shorted wire to the front camera module which renders the car inoperable, and is not covered by the extended warranty.

I have a 2014 Chevrolet Impala 2014 Ltz with 75000 miles on it. About a week ago I got a notification saying "service side detection" I lost my side detection on the side mirrors. Now my lane departure camera stop working and now my part assist for the rear camera has also stopped working. What's the point of paying more for a vehicle to be safe if all of the safety features start to fail.

My car has had a the side detection modules fail every 1 to 2 years since I've owned the car new in 2014. The dealership has repaired it for free every time now for at least 5 times. Now that the car is not under warranty they refuse to fix it for free. This is a problem with the design and engineering of the car and it is very costly to fix. The problem will continue to occur since the manufacturer refuses to find a permanent solution to the issue. It is related to the placement of the unit and it is affected by the environment and corrodes.

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.

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.

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.
