The right turn signal bulb keeps blowing. Break lights were stuck on. I got pulled over because the blinker wasn't working and parking light wouldn't go off. The officer was nice because I had just got the car and didn't give me a ticket, just a warning. Blinker on passenger side won't work with lights on and fuses for that side keeps blowing
cars trunk randomly pops open , it's a safety issue because something can fall out my trunk and cause other car an accident. will have an appointment to inspect soon. since I just got this car june 2026 and the first time it randomly popped open was back in August, it's October and I woke up to another random trunk opened incident.
I noticed water/dampness on two locations of my 2014 Chevrolet Impala (while it is stationary) 1. Floor carpet on passenger side front seat is thoroughly wet (see attached photos), with the dampness extending to the rear seats. 2.inside the trunk in area behind the rear wheel. Took the car to the dealership and they advised I would have to pay for diagnosis as well as repair. This is a manufacturing defect that May have resulted in damage to the interior carpet, structural panels - floor (possible rust). GM customer service nor the dealership is willing to absorb the cost and expects my (consumer to pay)
When the vehicle is stationary rainwater drains into the trunk and into the spare time compartment. There's a defect with the tail lights and seals between the trunk and rear of the vehicle. I'm not the original owner and wasn't aware anything had been documented on the issue. Furthermore, I didn't know there was an issue until 2017 when I needed my spare tire. Https://static.NHTSA.gov/odi/tsbs/2014/sb-10092869-0335.pdf - issue already documented, but I wanted to officially report my problem because I shouldn't have to pay out-of-pocket for the repair, only because I wasn't notified.

While driving on freeway about 70 MPH today on way home I opened sunroof. As normal the cloth sunroof retracted and seconds later the actual glass roof opened. Half way thought opening. The cloth caught or got stuck and I hear tearing sounds all around my head. The plastic piece that has the cloth cover attached looks like the adhesive just gave out and now the cloth is flapping down blocking view of rear of car.

The area in my trunk where the spare tire is kept, keeps filling up with water. It has also produce an odor that as the entire car smelling like mildew. The vehicle has been parked in my driveway for the past year.
I started noticing a very bad odor of mold and mildew coming from the A/C vents. I took the car into the dealer I purchased in early 2014. The dealer said they looked at it and could not find anything wrong. After I took it in again for a bad odor, they said there was a recall on the rear tail lights letting water in the trunk. A couple months later I checked the trunk and the carpet was all wet, when I checked the spare tire compartment it was 2 inches of water. I started checking everywhere and found the carpet in the front driver seat very wet. I took the car in again this time I knew it was going to be a big problem to fix, the car was now smelling so bad with mildew and mold even the service technician could hardly stand to sit in it at all. They have tried to change the underlay, and it still smells bad. …
My new car developed a horrible odor after only about 1.5 years of owning it. I had midas muffle look for the odor because I thought it might be a dead mouse or squirrel. At first they couldn't find it but on the second visit (your not going to believe this) they found some type of growth inside the car's frame rail on the passenger side of the car. The substance actually looked like some kind of mold or fungus growth inside the frame rail. I then took it to pohanka cheverolet, I brought them pictures of the mold/fungus, I brought them samples of the mold/fungus and showed them where it was located. There response to me was they didn't know what it was, they couldn't get to it and they can't fix it. They recommended that maybe their body shop could figure out something but it is not covered under warranty. …
