Example complaints

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

“Truck stalls every time I start slowing down for a stop sign or red light and sometimes when I turn corners. When idling it shuts off immediately unless I throttle to keep rpms up. Also stalls when I put it in reverse. I've been almost hit several times when pulling into an intersection. Replaced all known causes and nothing has fixed the issue. I have read in some sites I may need a software update from Dodge dealership.”

“We purchased a 2003 RAM 1500 3.7, in 11/07, the truck has not been running right, we took it in and 2 plugs melted, into the coil, the dealer replaced the heads on that side. We picked up the truck. And the serpentine belt fell off and froze the water pump, blowing another head gasket. This isn't the first time the pump had been replaced.”

“Driving down I-94 on 01/24/2006 from work going 70 MPH and oil gauge bottomed out, and I had a ticking noise. Pulled off the highway and had truck towed to the dealership. Was told the engine was shot due to sludge. I maintained a excellent 3000 mile oil change. Currently, the truck sits at the dealership and I owe $27000 on something I could not drive. Help!!”

“My heater fan went out, creating a dangerous driving situation during winter driving conditions. I checked the fuse which is good. I think there should be a recall for this problem. I am going to have to have it fixed and believe the problem is in the ignition and will be costly.”

NHTSA complaint #10252824, filed 2008-12, 76,000 miles

“I own a 2003 Dodge RAM 1500 2x4. Clutch was replaced at 36000 miles, and motor was rebuild at 46000 miles, both times under warranty. Each time I' had the oil changed there appeared to be a white substance building up on the oil cap as if it was condensation. I now have 88000 miles and have a ticking. Like a valve sticking, and continues to have this white substance. When it rains or I go through a puddle of water the belt starts to slip and all power is lost.”
