Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was tricked into buying this vehicle, being a first time buyer and divorced. Including this major fuel leak (which has not been established exactly where the leak is coming from) the transmission is gone. Even if the transmission is replaced the vehicle is still to hazardous to drive. I am at my wits end with this car because I still owe money on it.”
NHTSA complaint #717648, filed 2000-01“Nhtsa has received numerous complaints and service bullitens (according to NHTSA records accessable on the web) regarding the faulty design and frequent failure of this dangerous transmission. Why has the NHTSA not investigated this transmission and recalled it?”
NHTSA complaint #702369, filed 1999-01“Transmission is noisy upon engaging. Dealer was contacted, and recommended replacement due to internal problems. No warranty, repairwork being done. Provide further information.”
