The Jeep Wrangler has long been known for its off-road capability, but the latest generation is also well-equipped for everyday driving. The updated Wrangler comes with a host of modern conveniences and an improved look that still manages to stay true to its unique vintage style. However, like most modern vehicles, the new Wrangler comes with some issues. Wrangler owners have begun reporting a variety of issues related to the car’s new 2.0-liter turbocharged engine. These problems seem to be mostly related to software rather than any mechanical issues with the engine itself. They include everything from error codes while driving to unexpected cut-offs while accelerating or cruising along at steady speeds. If you own or are considering buying a new Wrangler, here’s what you need to know about its 2.0 Turbo problems and how you can avoid them:
What’s the Problem with the 2.0-Liter Turbo?
The issue with the Wrangler’s 2.0-liter turbocharged engine seems to stem from a software glitch with the car’s new connected vehicle technologies (CVT). These features are designed to provide travelers with added convenience and safety while on the road. However, they have also been linked to several issues with the new Wrangler, including engine issues. The software glitch has caused unexpected shut-offs while driving at steady speeds (such as on the highway), low power while accelerating, and error messages that say parts of the vehicle are “shutting down.” In most cases, the engine seems to restart with no issues once the vehicle has come to a stop. It’s important to note that the issue with the 2.0-liter turbo engine does not seem to be related to any potential mechanical issues with the engine itself. The engine itself has proven to be a reliable piece of equipment, with many owners clocking in regular driving distances in the tens of thousands of miles without issue.
Software Problems
As noted above, the issue with the 2.0-liter turbo engine seems to stem from a glitch in the car’s connected vehicle technology. The issue seems to be related to the car’s new nine-speed automatic transmission, which is used in the 2.0-liter turbo engine. The transmission is integrated with the car’s electronic systems, which allows it to make automatic gear changes to keep the car at the right speed. However, it also means that any software glitches with the transmission can affect multiple systems in the car. The transmission glitch appears to cause issues related to the 2.0-liter turbo engine’s acceleration and shut-offs while driving at steady speeds. It may also cause the check engine light to come on and error codes to appear in the car’s computer system.
Engine Error Codes
The glitch with the transmission can also cause error codes to appear in the car’s computer system. The error code E45 appears in the computer system when there is a problem with the transmission. If the code E45 appears in your Wrangler’s computer system, this is an indication that the transmission needs to be serviced. Other error codes related to the issue with the transmission include P0306, P1445, P0758, P1446, and P0805. The P0306 code is an indication of an issue with the car’s ignition timing, while the P1445 code indicates a problem with the car’s valve timing. The P1446 code indicates a problem with the car’s cam timing, while the P0758 code is an indication of a problem with the car’s torque converter. Lastly, the P0805 code is an indication of an issue with the car’s fuel pump.
Lack of Power During Acceleration
Drivers of the new Wrangler have reported a sudden lack of power while attempting to accelerate. The issue, which also seems to be related to the glitch in the transmission, can cause the car to hesitate while accelerating, hesitate while shifting gears, and feel like it is straining to reach the desired speed. However, the engine seems to settle back down once it has reached the right speed. If the engine in your Wrangler feels like it is struggling to reach the right speed, you may want to take it to the mechanic to check for engine error codes. If the car is equipped with a 2.0-liter turbo engine, you may have code P0306, which is an indication of a problem with the ignition timing. You may also have P1446, which is an indication of a problem with the cam timing.
Unexpected Cut-Offs While Driving or Cruising
As we’ve already noted, the transmission glitch can cause the engine to cut off while driving at steady speeds, such as on the highway. However, the issue can also cause the engine to unexpectedly cut off while cruising along at normal speeds. This issue only seems to affect the 2.0-liter turbo engine and not the 3.6-liter engine. If the engine in your Wrangler unexpectedly cuts off while you’re cruising along at a steady speed, it’s possible that you have a faulty throttle body. You may want to take your car to the mechanic to have the throttle body inspected and to see if it needs to be replaced.
The new Jeep Wrangler is a competent vehicle that offers an excellent off-road experience along with a comfortable and modern design. However, as with most modern vehicles, it also comes with a few issues. The new 2.0-liter turbo engine has been plagued with software issues that have caused engine problems, such as low power while accelerating and unexpected shut-offs while driving at steady speeds. The issues are mostly related to the car’s transmission, which is integrated with the car’s electronic systems. We recommend that owners of the latest Wrangler take their vehicles in for regular maintenance so that any potential issues can be caught early.
