“Strong fuel odor coming from vehicle. Fuel dripping from bottom of car near fuel tank. Found fuel lines rotting and causing leaks on multiple sections starting at the fuel tank up to the engine. Protective heat wrap holding moisture and causing lines to rot.”
NHTSA complaint #10895010, filed 2016-08, 77,500 miles“Leaking fuel lines above exhaust. Where the fuel line comes down out of the tank and runs forward, there is a holder that was wearing on the fuel line and caused a hole and a leak.”
NHTSA complaint #11098353, filed 2018-05, 73,000 miles“Fuel lines under the car, driver side rear started leaking fuel. The lines were rusted through and fuel leaked past the exhaust system where a potential car fire could have happened if not noticed right away. The vehicle was parked in the garage and off when I noticed the strong scent of gas and saw a small puddle of fuel under the car. Repairs were completed at porter Chevrolet service in newark, delaware. Repairs consisted of replacing the feed line and fill line. The estimate quoted was $800. Repairs ended up costing $480.”
NHTSA complaint #11160763, filed 2018-12, 105,000 miles“Wanted to change oil; had smelled gasoline from time to time; closer inspection showed leak at fuel tank area. Could not drive due to risk of injury to family, including two-year-old child.”
NHTSA complaint #10643229, filed 2014-10, 65,666 miles“The fuel lines that are wrapped in the heat protective tape on the driver rear side just as they turn up to go to the fuel tank are rusted out because the heat shield protector holds water on the fuel lines and now mine are rusted out and leaking fuel all over the ground by my exhaust. This is a major issue that hasn't been addressed with many chevy products. Now it's going to cost about $600 to replace the lines. Chevy is not taking responsibility with this defect and costing people money and putting lives in danger by having a leak prone line right by the hot exhaust. …”
