ABS light or ABS activating by model year
What owners say
The ABS computer brake module is bad in my jeep. It needs a replacement. Confirmed by Chrysler Jeep dealership. However, Chrysler does not offer a replacement module. ABS does not work on my vehicle. This is a huge safety issue and is common problem among this year Jeep. Chrysler shouldn’t be allowed to NOT have a replacement OEM ABS module. Huge safety risk and lawsuit
ABS control module has gone out
April 22, 2025 my 2008 Jeep lost power. There was a sequence, where one warning light was followed by another, followed by a complete loss of power. I charged the battery, car started up, I drove to dealer (a 5-minute trip), and by my arrival the Jeep had again lost all power. Dealer checked the vehicle, and told me the battery and charging system were fine, but the ABS brake modulator was draining the power. They have not been able to get another modulator and the vehicle is still at the dealer (Crown Chrysler Jeep Dodge Ram Dublin, OH). Losing power precipitously presents a safety hazard.
The vehicle requires an ABS module. I have been waiting for over 4 months for part availability. According to dealer they dont have any ETA on availability and have been told it may not be something they ever go back to producing. My state requires safety inspection which it will not pass due to this issue. Seems to me that someone needs to be responsible to make a part for these issues.
This is a common flaw with the abs brake system on many Chrysler Fiat vehicles and Chrysler fiat is doing NOtHING. My Jeep ABS computer module went bad . No damage, no off roading. Driving on highway and all the brake/abs/stability control lights lit up on my dash. The abs showed code “c2200” bad abs module and must replace. However Chrysler stopped making these …in back order for years. You have to either get a junk yard part or send your computer away to be Refurbished. How can Chrysler be allowed to not have a critical safety part in stock…and not cover this in a lifetime warranty. ?? I’ve never had any other vehicle where the abs computer goes bad . This is insane. And dealer can’t locate the part in the USA because Chrysler doesn’t have them.
ABS Module Yes As I was driving and going to turn left into a shopping center and stepped on the break, I had none, I did almost crash. It happened all of a sudden out of nowhere no lights, no icons lit. The problem has been confirmed by a dealer stating that this is a nationwide issue that’s currently going on that the parts are back ordered because there is nothing in production right now for the part. The vehicle is not drivable.
I have a 2008 Jeep Wrangler Rubicon that has a lifetime powertrain warranty. Since I purchased the vehicle in 2008 I have maintained it exactly as required to keep the warranty valid. This includes the 5 year lifetime warranty powertrain inspections which are performed every 5 years. I have documented proof of the inspections. In January 2024 my ABS brakes failed and I went to my local dealership where I purchased the vehicle. The dealership service department told me that my ABS module failed with a code of C2200 ABS Module Internal Failure. the part number is 68030936-AB. The dealership said they ordered the part from the manufacturer. Since January 09, 2024 I have called the dealership about the ABS module. They told me I could drive the vehicle and that it would brake, but the antilock brakes would not work. This ABS module also controls the Electronic Stability Program, and that does not work either. Chrysler has not manufactured the broken part. Chrysler sold me the vehicle with a lifetime powertrain warranty and this part is included in the warranty. However, Chrysler has failed to provide a replacement part or offered another vehicle to safely drive.
ABS brakes not working on my Jeep. Was told by dealer that it needs a new ABS module, but nobody has the part. How can I drive my vehicle when my ABS brakes are not working and you don't provide the part to fix it? The one dealer in Texas that has the part jacked up the price for it. That is price gouging, which is against the law. Chrysler is and will be responsible for any accident cause due to this issue.
Vehicle while driving, wipers start, horn blows, washer fluid sprays, abs light goes on, engine dies making braking and steering impossible.
Steering wheel shaking at about 50 mph. Then warning lights on dash came on ABS- ESP and BAS. I slowed down drove home and parked it. Can’t get into shop until next week. Jeep has less than 48,000 miles.Not safe to drive!
