Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I noticed a strong gas smell after a full tank of gas with my mercedes benz GL450 after I received it back from the mercedes benz dealer to replace the driver side fuel sending unit to fix the broken fuel gauge. The strong gas odor was non-existent before the repair. Initially, I thought it was just a residual smell due to the repair but after a week when I filled again, the gas smell was still there. The smell is so bad especially in the morning when I get inside the garage. The smell is evident on the rear passenger side close to the gas tank. …”
