Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Transmission failed on acceleration from stop. Brought to Chevrolet dealer who told me the 1st and 2nd gear came apart internally and that a complete rebuild was necessary. No prior indications of transmission problems (I.e. Slipping, noise, etc...). Will cost me over $3000 to repair. Searching on line, I found several other owners complaining about the same problem with less that 90000 miles on their vehicles.”
NHTSA complaint #10447231, filed 2012-02, 68,000 miles“Car stalled unexpectedly on freeway exit for no apparent reason with loss of power steering and all functions. Had to coast to a stop and luckily no other cars were behind us. Additionally, car fuel tank valve does not stop gas when fueling and causes gas to surge out of tank when fueled and onto vehicle. Reported this problem to dodge and they said this VIN no. Wasn't covered by recall.”
NHTSA complaint #10450599, filed 2012-03, 120,000 miles“Transmission failure, no warning signs. Vehicle felt like it popped out of gear. Truck does nothing in drive, only moves in reverse, 1st, and still does major slipping. Online research has informed me that this is a common issue among this type of truck.”
NHTSA complaint #10440515, filed 2011-12, 117,000 miles“Cracked dashboard on passenger side where airbag is fitted. Upper lefthand side of airbag. Traction control/stabilitrac system: service indicator warnings activate, switches from 2 wheel drive to 4 wheel drive high even though selector is in 2wd mode. The first occurrence of this was at 70k miles, then again at 90k. Then again at 97k the transmission was damaged and needed to be replaced. Again at 101k miles the ringgear in the rear axel was destroyed. Rear axel was replaced. …”
NHTSA complaint #10460647, filed 2012-06, 36,000 miles“While driving on the highway about 70-75 miles a hour, passing another vehicle, the passing gear engaged, then there was a loss of power to the vehicle. Once the truck got under 40 MPH you have no drive gear only 1,2, or 3rd gear will get you moving. Vehicle lost 4th gear.”
