What 630 owners told NHTSA about the 2014 Chevrolet Impala Eco Eassist

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.

Gages are going up and down. All lights keep coming on and appears to dying while driving. Turns dignals do not work when this is happening. My car has been with dealer (2298 Crain Hwy. Waldorf, MD 20601) for two weeks. As of Jan 3, 2023. They are offering to replace the chassis however not following the notified recall. Insisting that I pay...

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!

Electrical issues, radio volume disappears for a short period of time, turn signal audible noise disappears at same time radio volume stops, power sterring assist stops working for short time, sterring issue repaired in 2016 but doing again, ac cooling stops working for short time period, off and on, seems to be some type of electrical issue with the vehicle, purchased new in 2014, only 32,000 mile on car at present, every time taken to dealer will not reproduce the problem, called GM states recall 14515 is not part of my car, i question that in that this recall is for electrical issues. can not seem to get any furthur with anyone on this issue

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.

The contact later found that the wiring harness associated with this system was prone to corrosion and needed to be replaced. The vehicle was repaired however the failure continued to occur intermittently. The manufacturer was made aware of the failure. The approximate failure mileage was 44, 786.

The electronic parking brake fails to disengage entirely from the rear brake pads causing them to become welded together. This results in extreme heat, excess brake dust, poor acceleration, and caliper / brake line (air) issues.

The linx radio stopped working. The onstar system stopped working awhile after the linx radio stopped working when the car started to operate off of battery reserve (or what I think is battery reserve --- the light on the dashboard changed to blue). I've had to change the batter twice in 2.5 years. I'm told the battery Duralast is a good battery and that its an electrical fuse problem and it would be difficult to find which wire is the problem. The vehicle has been inspected by three different dealers in three different states. I was also told to uninstall onstar for resolution of the electrical problem of the battery draining and needing to draw energy from another source taking up more energy than it's suppose to in the vehicle. Yes, in 2017-18, the problem was confirmed by the dealership where I purchased the car brand new in 2014, Criswell Chevrolet in Gaithersburg, MD.

We have had several problems with the blind spot sensor on our 2014 Impala LTZ. Problems would always occur when driving in rain or snow. Dealer would just say that the sensor gets wet and that we should try to dry it off. Once the sensor was dry it would work ok. Now the sensor does not work at all. Took it off and it was full of corrosion. Reading online regarding reviews I find out that this is a very common problem with GM vehicles but GM refuses to do a recall. However they did do a special offer to replace the sensor if you have less than 80,000 miles. My car has 85,000 but I have dealt with this problem for several years. I replaced the sensor myself (at a cost of $400) and now they tell me it has to be reprogrammed. That really sucks. It is too bad that GM just can't accept the fact that they have a faulty product. I am currently waiting for a call back from the dealer to see what it cost to get sensors and wiring harness replaced (GM admits that there definitely was a problem and says you have to replace both sensors and the wiring harness). How in the world can this not be a recall!!!!!!!!!!!

HAVE HAD CAR AT DEALERSHIP 3 TIMES TOTAL FOR THE SIDE DETECTION SYSTEM MESSAGE/BLIND SPOT INDICATOR LIGHTS. FIRST TWO TIMES THE ISSUE WAS FIXED BECAUSE I HAVE THE MPP COVERAGE PLAN. THIS TIME MPP WOULD HAVE COVERED IT BUT MECHANIC SHOWS WATER INTRUSION. THEIR WAS A RECALL AT ONE TIME FOR VEHICLES UP TO 80,000 MILES. MINE HAS 124,000 SO NOT COVERED BUT WHEN I TOOK IT IN FOR THE SAME THING PRIOR DID NOT HAVE 80,000 MILES. SO EITHER PAY THE $900 OR PAY THE DIAGNOSTIC CHARGE OF $155 AND WALK AWAY WITH ISSUE NOT FIXED . SO MANY COMPLAINTS ON THIS AND GM HAS DONE NOTHING. IF I HAVE FIXED THE MODULE IS OVER $200 FOR THE ONE SIDE. IT KEEPS GOING OUT. GM SHOULD FIX THIS AND CREATE ANOTHER RECALL FOR THIS ALL SO COMMON ISSUE!!

RECEIVED LETTER FROM GMC IN MARCH 2020 REGARDING ELECTRICAL WIRE LEADING TO PASSENGER SEAT NOT DEPLOYING AND MAY BECOME DISCONNECTED AND FAIL TO DEPLOY WHEN COMMANDED. ALSO AN INDICATION WILL BE DISPLAYED ON THE DASHBOARD. MY CAR IS EXPERIENCING THIS ISSUE AND GMC FAILS COVER THE COST BECAUSE ITS NOT IDENTIFIED AS RECALL. THE STATES THEY WILL COVER FOR NO CHARGE IF WITHIN 8 YEARS OF ORIGINALLY PLACED IN SERVICE OR 80,000 MILES (WHICHEVER COMES FIRST). GMC SHOULD ALREADY THAT 2014 CARS WILL BE WELL 80,000 MILES IN 2020! SINCE THIS IS A SAFETY ISSUE AND LIVES ARE AT STAKE, GMC SHOULD NOT MAKE THIS FINANCIAL BURDEN FOR CONSUMERS. ADDITIONALLY THE ELECTRICAL WIRING FOR THE ENTIRE SYSTEM IS AN ISSUE. MY SCREEN CONTINUES TO BLINK IN AND OUT AND SHOW A SYSTEM REFRESH AND THE RADIO, BLUETOOTH CAPABILITY, AND LOCKING MECHANISMS ARE INOPERABLE AS WELL. ALL OF THESE ISSUES STARTED AT THE SAME TIME! GMC NEEDS TO TAKE THE SAME STEPS REGARDING AIRBAG SAFETY AS FORD HAS DONE FOR THEIR CONSUMERS WITH OUT OF WARRANTY VEHICLES! FORD IS PROVIDING A FREE SERVICE TO THEIR CUSTOMERS BECAUSE THEY VALUE THE LIVES MORE PROFITS. I'VE TAKEN VEHICLE FOR SERVICE TODAY (4/9/21) AND I'M LOOKING A A HEALTHY BILL. HOPEFULLY ELECTRICAL/SAFETY ISSUES CAN BE ADDRESSED WITH GMC AS THIS ISSUE HAS BEEN IDENTIFIED IN MULTIPLE FORUMS INCLUDING THIS WEBSITE. THE NUMBER ASSOCIATED WITH THE ELECTRICAL AIRBAG ISSUE IS N192216430. THE ELECTRICAL ISSUES WITH SCREEN AND AIRBAG WAS IDENTIFIED WHEN STARTING THE CAR AND NO CONNECTION AND AIRBAG INDICATOR ON DASHBOARD. THIS HAPPENED AROUND JUNE 2020. I SPOKE WITH CHEVROLET CUSTOMER ASSISTANCE CENTER TODAY (4/9/21) AND NO HELP WAS OFFERED FOR THIS ISSUE.*DT
