One problem related to engine funny noise has been reported for the 2006 Dodge Ram 1500. The most recently reported issues are listed below.
When raining the engine misfires to the point of stalling the engine and when hitting the gas the engine will big down when idleing for more that 10 minutes the engine idles rough and begins to putter and stahls out. The rear differential but came loose causing the pinion gear to shift which had resulted in a loud whirling sound when driving at any speed and gets louder when the faster the truck goes and also clunks when coming to a stop. When hitting the brake pedal the front passenger blinker/running light illuminates. Front driver side wheel bearing consistently fails after 8,000-20,000 miles causing a loud humming noise and causing me tons of money. Check engine light comes on telling me to check gas cap even though I've replace it twice now which leads me to believe there is a engineering defect and also through the code for misfire in cylinder 7 even though I've replaced the spark plugs and coils after the code was generated and it went if for about 4 weeks and came back on. I'm conclusion I believe Chrysler is knowingly selling unsafe and, unreliable vehicles which end to costing the consumer thousands in repairs and time something we can't get back. This has been happening since 20,000-40,000 miles into owning the vehicle. My vehicle was manufactured 05/2005 but is titled as a 2006 Dodge Ram 1500 slt crew cab.
