Example complaints

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

“I purchased a 2004 XLR in 2019 from an agent in fl. I immediately or with-in 200 miles I began to receive messages on my dash! First it was traction control that applied the brakes and caused the car to vet violently to the left as soon as I hit 65 miles an hour. Then the check gas cap followed by check engine lights came on. My Cadillac dealer was at a loss to solve the problem with traction control until they contacted the corvette engineers in bowling green, which took a week! They replaced the gas cap and that problem went away only temporally! …”

“A pronounced odor of gasoline and appearance of an error message stating check gas cap LED me to bring the vehicle, a 2004 Cadillac XLR, to the dealer for service. The dealer determined that a crossover pipe between the two gasoline tanks was leaking. Replacement of the crossover pipe (at a cost of $2295.14) did not cure the problem. When the same error message recurred the following day, I returned the vehicle to the dealer. I was informed that the feed pipe leading from the gas cap to the gasoline tank was leaking at its inlet. Replacement of this pipe silenced the alarm and error message. …”

“The contact owns a 2004 Cadillac XLR. The contact stated that fuel had begun to leak from the fuel pump without warning. The contact took the vehicle to an independent mechanic who diagnosed the failure and informed him that while the motor was running, the fuel would leak from the rear driver's side wheel; the leak would stop once the engine was shut off. The mechanic later discovered NHTSA Campaign Number: 11E009000(Fuel System, Gasoline) which he linked to the failure. The dealer was notified and an appointment was made for a diagnostic. …”
