Recalls and investigations

One recall on the electrical system covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

18V-332May 17, 2018
Electrical System:Wiring

Chrysler (FCA US LLC) is recalling certain 2014-2018 Dodge Journey, Charger and Durango, RAM 2500, 3500, 3500 Cab Chassis (more than 10,000lb), 4500 Cab Chassis and 5500 Cab Chassis, Jeep Cherokee and Grand Cherokee and Chrysler 300, 2014-2019 RAM 1500, 2015-2018 Dodge Challenger, 2015-2017 Chrysler 200, 2016-2018 RAM 3500 Cab Chassis (less than 10,000 lb), 2017-2018 Chrysler Pacifica and 2018 Jeep Wrangler vehicles. These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging. If, when using cruise control, there is a short circuit within the vehicle's wiring, the driver may not be able to shut off the cruise control either by depressing the brake pedal or manually turning the system off once it has been engaged, resulting in either the vehicle maintaining its current speed or possibly accelerating.

Risk and remedy
Risk: If the vehicle maintains its speed or accelerates despite attempts to deactivate the cruise control, there would be an increased risk of a crash.
Remedy: Chrysler will notify owners, and dealers will inspect the software, and perform a software flash on the engine or powertrain control module, free of charge. The recall began June 4, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Note: Owners are advised to stop using cruise control until the software update has been performed. In the event that cruise control cannot be disengaged while driving, owners should firmly and steadily apply the brakes and shift the transmission to neutral, placing the vehicle in park once it has stopped.

Software security vulnerability. Closed jan 5, 2016, led to recall 15V-508.

NHTSA summary
On July 23, 2015, Fiat Chrysler Automobiles (FCA) launched Safety Recall 15V-461 to remedy security vulnerabilities in approximately 1.4 million model year (MY) 2013 through 2015 vehicles equipped with Uconnect head units (HU) 8.4A (RA3 radio) and 8.4AN (RA4 radio) manufactured by Harman International.On July 24, 2015, the Office of Defects Investigation (ODI) opened Recall Query, RQ 15-004, to investigate HU security vulnerabilities and remedy effectiveness in the recalled population and to determine whether similar units have been supplied for use in other FCA vehicles.In an August 11, 2015 letter, FCA submitted a second Part 573 safety recall report expanding the scope of the Uconnect RA4 model radio to include additional 7,810 MY 2015 Jeep Renegade vehicles manufactured from September 18, 2014 through June 25, 2015 (Recall 15V-508).Scope analysis indicated that Uconnect radios installed in FCA vehicles not included in recalls 15V-461 or 15V-508 (subject recalls) are not equipped with built-in cellular access or short range wireless communication features and, thus, do not contain the security vulnerabilities addressed by the subject recalls. SUBJECT VEHICLES: MY2014 through 2015 Dodge Durango, Jeep Grand Cherokee and Jeep Cherokee sport utility vehicles; MY2013 through 2015 Ram 1500, 2500, 3500 and 4500/5500 pickup trucks; MY2013 through 2015 Dodge Viper vehicles; and MY2015 Chrysler 200, 300, Jeep Renegade, Dodge Charger and Challenger vehicles.According to FCA, long and

Totally integrated power module failure. Closed jul 24, 2015.

NHTSA summary
In a letter dated August 21, 2014, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a defect investigation of alleged failures associated with the Totally Integrated Power Module (TIPM) installed in Chrysler SUV?s, trucks, and vans beginning in the 2007 model year. The petitioner alleges that TIPM defects may result in engine stall, airbag non-deployment, failure of fuel pump shutoff resulting in unintended acceleration, fire, and other symptoms. On September 25, 2014, the Office of Defects Investigation (ODI) opened DP14-004 to evaluate the petition for a grant or deny decision. ODI analyzed complaint data provided by CAS as well as complaints submitted to ODI from consumers. In total, there were 296 complaints submitted by the petitioner in the original petition and five supplements, including 271 complaints related to the subject vehicles equipped with TIPM-7. Approximately 3 percent of CAS complaints are related to vehicles equipped with TIPM-6 and ODI?s review of these complaints did not identify any safety defect trends. ODI conducted a detailed review of complaints narratives submitted by CAS and consumers including careful analysis of vehicle repair histories, warranty claims obtained from the manufacturer and any available Customer Assistance Inquiry reports (CAIR). Analysis of the field data indicated that MY2011-2013 Jeep Grand Cherokee and Dodge Durango vehicles exhibited significantly higher compla

“Service electronic braking system / ABS service antilock brake system. Both these lights come on and ding, half a second later they are off. This happens non stop, looks like everyone is having this problem. This should be a recall not a $1200 fix. I only have 58,252 miles on my truck.

Should you keep driving it?

This page can't tell you that. 1 of 46 reports involved a crash. 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.
