When my car is exposed to water (rain, a car wash) the trunk completely floods and does not drain. It has flooded so much now that my amplifier does not work. I took my vehicle to Chevy to have the known recall on this vehicle repaired but Chevy claims that they will not do anything for me. I am afraid that the car can potentially catch fire and burn my home down as I park this car in my driveway. With this being a known recall for this vehicle, can I please have this fixed immediately!!!! I have already replaced my tools that have been damaged, please just have this fixed or id likely take further steps after this. I have been going back and forth with GMC and Chevy for over 7 days now! Just recently, my car was producing sparks from the trunk area, THIS IS NOT GOOD!!!

For approximately 2 months, my 2016 Impala LTZ, would display a message on the small screen in front of the driver in the dash, stating for the driver to, "press ignition button again to turn vehicle off." The worst part about it was this would happen very randomly whether I would be driving in city traffic, or be sitting in a parking lot at a local store. I took it to my local Chevrolet dealership. Five different times, because they were not able to get the occurrence to duplicate for them. They replaced the ignition, as well as other suspected parts with no resolution. Resolution. Ended up costing me over $1,200. That was the first time I took it in for this issue. The other four times didn't cost me anything because they hadn't fixed the issue. Come to find out it was a wire on the body control module that had some of the insulation sheathing removed, which then in turn caused the wire to ground out on the car's frame. Just thought I would put this out there in case anybody else goes through it because it wasn't real inconvenience.

All instruments failed. After a couple restarts they came back on. Lane departure alert doesn’t work now. From a web search, I’m afraid it’s just the beginning. No, I haven’t taken it to the dealer; they charge for diagnosis. And it hasn’t been inspected. The problem doesn’t act up all the time. There are no warning lights, the system just fails. I have 50,600 miles on it. If you find what I’ve found in my web search, the cost of repair is staggering, especially for retirees. I hope you look into Chevrolet’s problem they’ve been having with the Impala.

I parked my car at work and worked a full day Saturday the 13th of November. I go out to start my vehicle and 3 warnings appear all at once. Stabilitrak, ABS, and power steering. Reading online I’m not the only one but with only 109,xxx miles it’s kind of BS that there’s obviously an engineering flaw with these vehicles and I probably will give a few car payments worth to get this fixed. I’ve owned this vehicle since 17,xxx miles

After starting car (and sometimes put in reverse), steering appears locked and message says to get power steering serviced. After putting back in park, power steering starts working. This happened multiple times last few weeks. Took car in to Joe Johnson Chevorlet (Troy OH) for scheduled next morning service. After 2 full days of excusses why they couldn't get to our car, we picked it up and took it to independent service shop. He test drove it and steering was fine. Got car back and next day it happened multiple times again. Took it back to independent to run code, which did not give exact problem. Drove car 1 block and power steering went out turning. Then again 1 block later. It is now parked and afraid to drive it. Chevy seems not to want to work on it and independent does not know what is wrong, said it could take him up to a week to trouble shoot entire system. He hasn't got back to me yet. HELP! Also, parking brake seems to engage by itself overnight. When starting car, sometimes it is on. We never use it. This may be related.

1. The display screen went black while driving using navigation. The fault was a defective hmi module, gm part # 84296482 at a cost of $1100 (see attached document). The sudden loss of the screen was disconcerting and could have caused an accident. This should lead to a recall and reimbursement of the repair cost. 2. When the adaptive cruise control (acc) causes the brakes to be applied it does so very suddenly and in the ABS "chattering" mode even when there is no collision danger. This produces a jolt to the drivers and occupants which is an unexpected and unsafe response.
