2018 Ford Expedition: Common Problems & Issues

The 2018 Ford Expedition marked the beginning of the fourth generation of this popular full-size SUV. While it brought significant improvements in terms of design, technology, and performance, like any vehicle, it's not without its potential issues. If you're considering buying a used 2018 Expedition or already own one, it's crucial to be aware of the common problems reported by owners. Let's dive into the details, guys, so you know what to watch out for!

Transmission Troubles

One of the most frequently reported issues with the 2018 Ford Expedition revolves around its 10-speed automatic transmission. Owners have described a range of problems, from harsh shifting and jerking to hesitation and complete transmission failure. These issues can significantly impact the driving experience and, in some cases, render the vehicle undrivable.

Guys, let's break down the specifics. Some owners report that the transmission slips between gears, especially during acceleration or when climbing hills. This can feel like the engine is revving without actually transferring power to the wheels. Others have experienced rough downshifts, where the transmission clunks or jerks noticeably when slowing down. In more severe cases, the transmission may fail altogether, requiring costly repairs or even replacement. It's definitely something to keep an eye on!

Several factors could contribute to these transmission problems. One potential cause is a software glitch in the transmission control module (TCM). The TCM is responsible for managing the shifting behavior of the transmission, and if it's not properly programmed, it can lead to erratic shifting and other issues. Another possible cause is wear and tear on the transmission's internal components. Over time, parts like clutches, gears, and valve bodies can degrade, leading to transmission problems. Regular maintenance is key to preventing this!

If you're experiencing transmission problems with your 2018 Expedition, it's essential to take it to a qualified mechanic for diagnosis and repair. They can scan the TCM for error codes and perform a thorough inspection of the transmission to identify the root cause of the problem. Depending on the issue, the mechanic may recommend a software update, component replacement, or a complete transmission rebuild or replacement. Don't ignore these symptoms, as they can worsen over time.

To mitigate the risk of transmission problems, it's crucial to follow the manufacturer's recommended maintenance schedule. This includes regular transmission fluid changes, which help keep the internal components lubricated and prevent wear and tear. Also, avoid aggressive driving habits, such as frequent hard acceleration and braking, as these can put extra stress on the transmission. Treat your Expedition kindly, and it will treat you kindly back!

Issues with the Engine

Another area of concern for 2018 Ford Expedition owners is the engine. While the Expedition's EcoBoost engine is generally reliable, some owners have reported issues such as excessive oil consumption, turbocharger problems, and engine misfires. These issues can affect the engine's performance, fuel economy, and overall reliability. Let's get into the nitty-gritty!

Excessive oil consumption is a relatively common problem in some 2018 Expeditions. Owners have reported needing to add oil frequently between oil changes, sometimes as often as every 1,000 miles. This can be a sign of worn piston rings or valve seals, which allow oil to leak into the combustion chamber and burn along with the fuel. It's like your engine is secretly drinking oil!

Turbocharger problems are another potential issue with the 2018 Expedition's EcoBoost engine. The turbochargers are responsible for boosting the engine's power output, but they can be prone to failure due to factors such as oil leaks, overheating, and wear and tear. Symptoms of turbocharger problems can include reduced power, whistling noises, and excessive smoke from the exhaust. Nobody wants a smoky Expedition!

Engine misfires can also occur in some 2018 Expeditions. A misfire happens when one or more of the engine's cylinders fails to fire properly, resulting in a loss of power, rough idling, and a check engine light. Misfires can be caused by a variety of factors, including faulty spark plugs, ignition coils, or fuel injectors. Misfires can be a real headache!

If you're experiencing engine problems with your 2018 Expedition, it's crucial to have it diagnosed by a qualified mechanic. They can perform a compression test to check for worn piston rings or valve seals, inspect the turbochargers for leaks or damage, and use a scan tool to identify any misfiring cylinders. Depending on the issue, the mechanic may recommend replacing worn parts, repairing leaks, or performing an engine tune-up. Getting it checked out early can save you big bucks later!

To prevent engine problems, it's essential to follow the manufacturer's recommended maintenance schedule. This includes regular oil changes, spark plug replacements, and air filter replacements. Also, avoid using low-quality fuel, as it can damage the engine's components. Treat your engine with respect, and it will reward you with years of reliable performance.

Issues with the Electrical System

The electrical system of the 2018 Ford Expedition, while sophisticated, has also been the source of some complaints. Owners have reported problems such as malfunctioning infotainment systems, faulty sensors, and issues with the power windows and locks. These electrical issues can be frustrating and can sometimes affect the vehicle's safety and functionality. Let's shine a light on these problems!

Malfunctioning infotainment systems are a relatively common complaint among 2018 Expedition owners. The infotainment system controls many of the vehicle's features, including the radio, navigation, and climate control.
