2006 Ford Ranger Problems

What owners report

Most complaints for this model year concern two things: the open Takata driver and passenger frontal air bag inflator recalls, which many owners describe as unresolved for months or years because parts were unavailable, and rust in the rear frame, crossmember and leaf-spring shackles. Reports of frame corrosion appear across a wide mileage range, from vehicles with only a few tens of thousands of miles to ones past 150,000, and several describe components such as the spare tire carrier or a spring shackle coming loose while driving.

1. 1
   Body and structure

   Rear frame and crossmember rust

   • 41 complaints (15%)
   • median 90,700 mi at 12.0 yrs old (33 state mileage)
   • filed 2013–2022

   Complaints describe the rear frame, the crossmember that carries the spare tire, and the gas tank support brackets rusting through, sometimes while the body panels still look clean. Owners report the spare tire dropping or hanging low, the EVAP canister breaking when the carrier fails, and inspections failed because of rusted spring perches and shackle mounts. Several say a mechanic told them the frame was beyond welding and needed replacement or the truck was not worth fixing. Reported from about 18,000 to 190,000 miles; many involve vehicles driven in winter-salt areas, and some owners note corrosion already present when the truck was a few years old.

   What to check: Get underneath and probe the rear frame rails, the crossmember above the spare tire, the fuel tank straps and brackets, and the area around the rear spring hangers. Have a shop inspect it on a lift if there is visible scale or flaking.

   “Frame is rusted out will not pass inspection. Spare tire holder rusted out. Tire would have fallen out. Cross member rusted out. We have a metalworking shop and will weld and repair ourselves at great time and expense. Point of rustout is near where the front bracket is to hold the spring. Give e-mail and I can send pictures.”

   NHTSA complaint #10678187, filed 2015-01, 115,000 miles

   “Purchased this vehicle in 2007 with 8k miles and had some rust on the frame. Now, 2013 I have 24k miles and the frames is completely corroded and my brakes are failing due to the rust. Have already sanded the frame and painted, but the rust comes back. This a big safety concern because parts can break while driving.”

   Air bags

   Takata air bag inflator recall not completed

   Mentioned in 12 of 60 sampled complaints

   Owners describe receiving repeated recall notices for the driver and passenger frontal inflators while the dealer says the parts are not available or that the vehicle does not qualify by region. Some report the air bag warning light staying on after a recall visit, others that only one side was repaired, or that a replacement inflator was an equivalent part rather than a final remedy. A few describe air bags deploying in low-speed or no-impact situations, and others describe them not deploying in a collision. Raised throughout the sample from about 7,000 to 220,000 miles, and concentrated in vehicles that received recall notices from 2015 onward.

   What to check: Ask for written confirmation that both driver and passenger inflator recalls have been completed, and check the air bag warning light on the dash with the key on. A dealer can run the VIN against open campaigns.

   “Takata recall a new airbag inflator was installed but it does not rectify the issue. The airbag was replaced with an equivalent version. This does not solve my issue that it can rupture. I do not feel safe driving my vehicle while this recall is still open and with no remedy available.”

   NHTSA complaint #10979894, filed 2017-04, 76,048 miles

   “I have gotten numerous notices of recall and have taken my Ranger to the local Ford dealer , spradley fore in pueblo colorado. They scheduled me an appointment and then told me upon arrival they did not have the parts and couldn't replace the air bags. They said Ford was concentrating on areas of the country with high humidity and pueblo, colorado did not qualify. I have now gotten notices not to drive the vehicle.”

   Suspension

   Rotted leaf-spring shackles and hangers

   • 20 complaints (7%)
   • median 90,700 mi at 10.9 yrs old (19 state mileage)
   • filed 2013–2022

   Owners describe the rear leaf-spring shackles and their frame hangers rusting through and separating, which lets the leaf spring sit against the bed or shift the rear axle. Symptoms include a clunk or grinding from the rear over bumps, poor stability and steering feel, and in some accounts the spring breaking free while driving. Repair descriptions range from welding plates onto the frame to full frame replacement. Mostly between about 53,000 and 170,000 miles, and frequently tied to the same frame corrosion noted above.

   What to check: Inspect both rear shackles and their frame attachment points for heavy scale, thinning metal or cracks, and check that the spring sits squarely under the frame rail.

   “Rear leaf-spring shackles and hangers on my 2006 Ford Ranger are rusted out, one of the shackles broke free from the frame while I was driving, made it harder to steer because the truck felt nowhere near as stable as it was before it broke, it caused me to swerve into the lane beside me which very well could have caused a serious accident if someone were to be there. …”

   NHTSA complaint #10918444, filed 2016-10, 245,000 miles

   “The rear shackles rusted through and broke off from the leaf springs. This happened while driving home from work on city streets. When turning corners the sound of the broken shackle rolling back and forth on the back of the bumper alerted me to the situation. I am third owner and this truck has been taken care of very well”

   Fuel system

   Engine stalls from fuel inertia switch tripping

   • 14 complaints (5%)
   • median 43,000 mi at 5.0 yrs old (13 state mileage)
   • filed 2007–2023

   Complaints describe the fuel pump inertia cut-off switch activating during ordinary driving, such as over bumps or potholes, cutting engine power immediately. Owners say the switch has to be reset by hand and cannot be reached from the driver's seat, and some report repeat towing and dealer visits where the switch tested normally and was not replaced. Reported from a few thousand miles up to roughly 145,000 miles, with several cases recurring once or twice a year.

   What to check: Ask whether the inertia switch has ever tripped or been replaced, and locate the switch and its reset button so you know how to reset it if the engine cuts out.

   “As I was driving headed to my doctors appointment down the freeway and as I exited the off ramp my vehicle shut off with traffic be hide me and I coasted off to the side. I learned that it was my inertia switch that cause my vehicle to shut off. The vibration of the road reflector and small potholes which cause inertia switch to shut the vehicle off. My truck has stalled out after exiting the freeway and on small streets. …”

   NHTSA complaint #11319795, filed 2020-03, 145,000 miles

   “I own a 2006 Ranger 3.0 auto. That has 35,300 mi. The fuel delivery inertia switch has kicked out under normal driving conditions twice. First time at 32,172 mi. And had to be towed to a dealer. The technician reset the switch and I had no problems until 35,100 mi. This time I was lucky enough to be in a parking lot, instead of out in moving traffic. When tis happens, the engine, of course, dies immediately. The switch cannot be reset while sitting in the driver's seat. …”

   Engine

   Misfire and rough running (3.0L V6)

   Mentioned in 7 of 60 sampled complaints

   Owners describe misfire codes, rough idle, hesitation on acceleration and occasional stalling, with the check engine light on. Several cite a Ford service bulletin on exhaust valve seat recession and say the repair involved cylinder head work; others report repeated tune-ups that did not resolve the misfire. A separate group of complaints describes timing chain tensioner and cassette failure on the 4.0L V6 resulting in a no-start. Misfire reports cluster between about 35,000 and 160,000 miles; the timing chain reports appear around 70,000 miles.

   What to check: Scan for stored and pending misfire codes before buying, listen for a timing chain rattle on cold start in 4.0L trucks, and ask whether any cylinder head or valve work has been done.

   NHTSA complaint #10325426, filed 2010-04, 34,000 miles

   “2006 Ford Ranger v6 3.0 biggest problem. Multiple cylinder misfire. Replaced multiple parts already nothing has worked. Engine code showing misfire in cylinder 4,5,6. Multiple misfires. Looked online many others with the same problem.”

   NHTSA complaint #10639188, filed 2014-09, 128,000 miles

Buying note. Before purchase, confirm both air bag inflator recalls are closed and have the rear frame and spring shackles inspected on a lift, since frame corrosion is the most common reason these trucks are described as beyond economical repair. A pre-purchase scan for misfire codes is also worthwhile on higher-mileage examples.
