Question

What is the most common problem with a Ford Ranger?

Common issues for a Ford Ranger include gearbox slippage, a leaky or failing crankshaft, and engine misfires caused by clogged fuel injectors.

The Ranger, one of the most popular car models from the Ford family, is popular as a compact pickup, but it’s not without its share of problems. Here are some common problems with Ford Rangers and their possible causes.

Transmission problems

Some owners have reported that the automatic gearbox in a Ford Ranger slips when shifting from 2nd to 3rd gear and from 3rd to 4th gear. Though there’s a misconception that the gearbox slippage is just a normal torque converter function, this may actually be due to a faulty valve assembly. Transmission fluid leaks can also arise due to leaks in the transmission fluid. A faulty transmission on a Ford Ranger can also cause problems like a dragging clutch and a burning smell while driving.  You might also find the same issues with an older Ford Ranger with a manual transmission. The root cause can be figured out only after a qualified mechanic opens the gearbox and inspects it thoroughly.

Leak in crankshaft seal

Many generations of the Ford Ranger have had a problem with a seal that leaks around the crankshaft, causing oil drips. This could be due to a damaged valve cover gasket or a faulty oil pan. Also, the crankshaft seal is one car part that is subject to immense stress, making it easily prone to wear and tear. 

Engine problems

Common engine problems on a Ford Ranger include a turbo failure and engine crank damage, which causes excessive overheating, dark smoke from the exhaust, and a dip in fuel economy. Engine problems can land your car in serious trouble. Thus, it is always better to consult a mechanic right after you’ve spotted any faults.

Crankshaft sensor failure

The crankshaft sensor is responsible for reading the engine’s RPM and position, then feeding that data into the ECU to regulate the time of fuel injection. Intermittent crankshaft sensor failure is a common problem with a Ford Ranger. A dip in fuel efficiency, engine misfires, and sluggish acceleration are some of the aftermaths of a faulty crankshaft sensor. There is also a possibility that your Ranger won’t start due to a faulty crankshaft sensor.

Fuel injector issues

Another problem with a Ford Ranger is with its fuel injector. A clogged or dirty fuel injector in your Ford Ranger will lead to an imbalance in the air and fuel supply. This, in turn, can cause problems like engine stalling, rough idling, engine misfires, a significant drop in fuel economy, etc. A faulty fuel injector can also result in the Tachometer needle (RPM needle) making unusual movements. A fuel injector problem with your Ford Ranger also takes a toll on the engine performance, making it difficult to drive, particularly when you are in off-road conditions.  An experienced mechanic can easily fix the issue for you. It’ll cost you around $350-$500 for a replacement fuel injector, with labor costs extra.  

Your Ford Ranger might not be as dependable as, say, a Toyota Tacoma. Even so, a well-maintained Ranger can easily last up to 250k miles, making it a fairly reliable option if you’re looking for a good-looking ‘go-anywhere’ truck.
