Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2008 Dodge RAM 1500, 2500 Pickup lead in one area — the air bags, 142 of 578 reports (25%), well ahead of the next concern. That matters, because the air bags are also the target of recalls 15V-313 and 16V-352 on this vehicle — so the single most useful check before buying or servicing one is confirming they were actually performed. 44 of the reports describe a crash and 7 a fire — a small share of the total, but worth weighing against the air bags pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
