I just purchased a 2019 chevy equinox premier and I found water in the spare time wheel well. After some investigation, I found there is a water leak causing water to spill on the fuse box located in the back panel on the driver's side. This is certainly a safety issue if the fuse panel shorts out, especially if it happens while driving.

Water leak flooding the rear passenger compartment floor and the rear spare tire well. The water appears to be entering at the rear pillars. On the left rear leak, it is entering the fuse panel. The right rear leaks by the power outlet. I fear this is going to cause corrosion and create problems in the future. I removed almost 2 gallons of water from the rear floor with a carpet extractor. I was able to pull a drain plug in the rear spare tire well to remove that water. The moisture in the vehicle condensates on the inside windshield, moon/sunroof and the rear back glass making it difficult to leave in an emergency without first wiping all the window down with a towel. FYI: I am the brother of the vehicle owner. She has stage 4 lung cancer and I am handling things for her.

Water leaks into the rear of the vehicle from The shark fin (I am told from the dealership GM I purchased the car from). It has however now entered into the fuse box and is getting fuses wet which IS a safety issue if they were to short while driving in a rainstorm. This is a major issue with multiple reports online on forums and complaint boards.

The sunroof drains on my vehicle keep getting clogged with debris even though I don't open the sunroof. I have had to get the drains blown out every 1 to 2 months when I find water in the rear cargo area. Attached are invoices from the dealership showing the work done and how often. An Engineer from GM has determined on April 10th that if these drains are frequently clogged, then it is a "Vehicle Concern". GM says that this is a maintenance issue. However, THEY have been doing this "maintenance" ever 1 to 2 months and the drains keep getting blocked. This can't be right! I don't want mold to grow in my car. A prior Equinox that I owned was "totaled" by my insurance company because water leaked into that car and mold grew in the interior.

While traveling a message appear "power reduced" a noise was heard like whistle (air whooshing). The time Car was started the engine light was on. The car was serviced by GM/Chevrolet dealership service. They found water in the spare tire compartment, but didn't not agree that it was the cause of malfunction. The asked if the car had been in a flood. I did my own research and found that this water leak problem is a known issue in litigation.

I started noticing that water was soaking the floor mat on the drivers side of the car after it rained or I went through a car wash. I took the car to a repair shop and they notified me that the bottom of the car is not welded properly from the manufacturer, so the space where it should have been welded together has left holes on both sides of the bottom of the car. These holes provide an area where water leaks into the car and continuously soaks the floors. There is also information from gm that states other 2010 chevrolet equinox cars have had this same problem, so it is clearly a manufacturing problem.

In april of 2015 I purchased a 2006 chevy equinox from sid dillion chevy dealership. Approximately 1 month after having the vehicle it rained and water had leaked into driver side floor board. When I started the vehicle it started but there was no acleration and the car wouldn't drive when put in gear. I informed the dealership and was instructed to bring the vechical back out the dealership to be looked at. In finding they informed me that it was sunroof drain that backup and leaked water into my driver side floor board, also leaking water on to the throttle sensor which is located on the gas pedal. They informed me that drain had been blown out and the error code was reset and the vechical ran again. This problem happened again a few months later and I was again instructed to bring the vehicle back to the dealership, this the same procedure was done as before and I asked what can be done to fix this problem and was informed that due to the design of the sunroofs drain, when it rains I will have water that leaks into vechical if there is large amounts of rain and that because there are no broken parts the problem can not be fixed. I informed chevrolet main center of the issue and was informed that there has never been any recalls on the vechical and to take it to the dealership to have the problem fixed. I've taken preventive measures but keeping the drian cleared and when the problem happens resetting the error codes, but last week 06-07-18 I had the line cleared and the following day it rained and the throttle sensor errored reset the code and vechical ran. Yesterday while driving I got caught in heavy rainfall the vechical completely stopped in the middle of a 4 lane busy road and would not move, water began leaking into the driver side and also from the pedal and intior lights. I'm very fearful of driving the vechical. This problem is very dangerous and unsafe.

Any time there is rain or going through a car wash my car has a leak of water that collects in my floorboard. I have read a million reviews online at chevroletforum.com and numerous youtube videos documenting the same problem with the make and model. If gm plans on charging for an upgrade like a sunroof then it should properly work. The reason for concern on this, the water leaks through the dash and even sometimes collects in the light fixtures of the roof. With standing water on the floor boards I have a huge concern for my safety from being electrocuted or being e posed to any type of mold caused from the wet carpet. There are apparently issues with several seals when it comes to this model and I feel it has been overly documented that is is a safety concern. Not to mention of driving in rain which is sometimes inevitable, you will be driving in your own monsoon. I have contacted the dealer and the are refusing to state that their is any safety concern. However, they are not driving my vechicle, I am. I have even personally emailed chevrolet about the issue and they are stating since there is no active recall opened that everything will be an out of pocket expense even though this is a design, hardware malfunction. Not something cause by wear and tear, like tires or brakes. This leak has also been know to start causing electrical issues from power lines being saturated in standing water. My car starts making a clicking noise and the power will fluctuate because of water leaking inside cabin and underneath dash where power cables are exposed. This has caused my car to stop working while driving on the highway previously.
