Service 4WD light on other Cherokee years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2022.

What this problem usually is

This sheet covers a "Service 4WD" message, a service all-wheel-drive warning or a failed power transfer unit (PTU). On this site it's mostly a Jeep Cherokee story: the light comes on, and the dealer names the PTU.

Is this a known problem?

The manufacturer has sent NHTSA 6 service bulletins or notices for the 2017 Jeep Cherokee that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“Started getting " service 4WD system" message at @ 84k miles. Took to Jeep dealer. Code C14A7-97 Internal transfer case failure. Was quoted $3627 for new transfer case and part not available. A car with low overall mileage should not be experiencing these kind of issues. Seems to me that this is a manufacturer problem.”

“At 38,700 miles, the PTU started to fail. 4WD service unavailable message displayed permanently as well as svc 4WD light. Sometimes while driving there is a loud buzzing sound. June 2025 Dealership found code C14A7-97 and states replacement is needed. Due to low mileage, should be considered for the warranty recall.”

Should you keep driving it?

This page can't tell you that. 1 of 186 reports involved a crash and 2 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
