“I notice that the tank has been leaking fuel. This occurs when I fill up the tank and/or the fuel swishes or moves around. This happens on the rear left tire. It seems to get on the exhaust or heat up and smell excessive fuel. I noticed this when I would park for at least 20 mins on a full tank. I am a fuel tank engineer and see this as a poor design possibly”
NHTSA complaint #11397052, filed 2021-02, 138,000 miles“Metal fuel lines in rear left of vehicle leaked profusely due to rusting out. Car stalled and had to tow home. Had to replace line with rubber fuel hose. Noticed strong smell of gas but I assumed it was because I was near a gas station.

Due to GM strike in 2019 and resulting parts shortages, my car was out of service for 4 months. …”

So, I did on line research and people saying the gas cap was bad. I took it off and it looked fine. Check engine light was still on. So, I called the dealer to make an appt.

NHTSA complaint #11302112, filed 2020-01, 168,000 miles“Fuel supply and return lines are rusting through. Leak started just under the drivers side rear door. Upon inspection both lines need replaced completely. I took it to a mechanic and had a patch piece put in on the affected line, but was told this is a common problem with these cars caused by bad design and poor choice of materials. The problem was first noticed when car was stationary and took longer than normal to start. I noticed the smell of gas and there was a visible spot of gas on the ground under the car.”
