Anyone had this issue? On top of all my other issues I am now getting a warning intermittently that says "Service electronic parking brake"

My wife just told me this happened on our Renegade this morning. She pulled over to check it and then the light went out on it's own and didn't come back on for the remainder of the drive. We have around 1500 miles on it I think and it's the 1.4T / Manual. Anybody else seeing this?

BrianR383 - are you still seeing the problem or did you have your local Jeep Service Department investigate?

An update on this: I made an appointment to have the dealer service look at it, but then decided to disconnect and reconnect the negative battery connector. I disconnected it for 5 minutes, then hooked it back up. At this point the connector did not want to engage tightly with the battery terminal. It took several tries to get it properly seated to the point where I couldn't wiggle it loose. It just has the plastic tab that you close without using any tools and I can't see any kind of adjustment I could make to tighten it. Has anyone else found a way to tighten it or is there a connector out there that would work better?

Anyways, after doing this the Parking Brake warning has not happened at all. It got me thinking that maybe the battery connector was loose the whole time and that's why the warning light was sporadically coming on.

Warning to others, you do lose your average mpg when you disconnect the battery so use a hand written log or fuelly to track the mileage long term.

I cancelled the dealer appointment and all has been well for the past 2 weeks.

Electronic Brake Warning

Hi guys,
Purchased my Trailhawk and started having a problem in the first day. When I am driving, the electronic brake warning comes up and the red brake light flashes.

The brake button below the gear keeps flashing in an irregular way like there is a connection issue somewhere

 

[BrianR383]

I've had issues with that warning light popping up randomly for a year now, its one of the many many issues I have, but the dealship has never been able to replicate it or fix it. I don't really have much advice, hopefully you have better luck resolving it than I have.

that's horrible man! What else did you experience? Anything major?

I get a ton of warning lights all the time, Svc 4wd, svc airbag, svc esc, svc parking brake, etc.


My traction control light randomly comes on and I lose power/throttle response for around 10 seconds. This problem is fairly new.


Lately my trailhawk just randomly shuts off.


I had to have the brake rotors and pads replaced at 2k miles because the pads were coming apart according to the dealer.


I randomly get a misfire code for one of the cylinders.


And finally the dealership had to replace part of the wiring harness for the IAT sensor because it quit working. So yeah, I've had a lot of issues.

Try disconnecting the negative battery terminal for 45 minutes and reconnect.
This seems to fix general sensor issues. If it persists, take it to the dealer.
Hope you get it solved!

I've done that multiple times with mine, I've even left it disconnected overnight numerous times and it's never fixed the problem, neither have the 12 or so dealer visits and the almost 60 days total not its been in the shop throughout all the visits.

Hi ozgunique,

I'm so sorry to hear about this! Have you brought this to your local dealership's attention?

That seems dangerous, looks like they need to replace your car with a new one

Thanks for the advice! Don't want to do anything on my own, the dealers sometimes give you trouble for touching anything.

Hi Erica,
I called them and they said it needs to be towed. I am out of the country for a couple of days but will do that when I get back.

Sounds like a faulty connection somewhere could be a bad earth ... garage computer can't always detect this .. I bet it's something simple to fix .. problem is finding it .. especially if the faults are intermittent ..

I had to replace a battery once that caused problems ..

Intermittent problems are a barrel of fun. Had my fair share of chasing them in the past.

As for a garage computer can't always detect this, I know that only too well.

Volvo wouldn't start. Had fuel and spark. Ok, so out with the Snap On box of tricks and see what the problem was. Came up as ECU fault. Had a spare known working ECU with matching numbers. Swapped it over and Volvo still wouldn't start. I then took the ECU out of mine, checked numbers, all matched and put that in. Still no joy. ECU fault my @rse. On the bottom of the distributor near the bulkhead, there is a small three pin multi plug. Swapped the distributor and the Volvo started. The multi plug was faulty. Would have found that without playing silly sods changing parts when there was no need to, thanks to garage equipment. Oh the joys of working for oneself!

I agree. I got nowhere with FCA though so all my documentation has been given to an attorney and I will have to wait and see what they end up working out with FCA.

 

[ozgunique]

So do you guys think this is dangerous or harmful to the car to drive, at least to the dealership or does it look like a faulty connection?

 

[logan5]

Thanks for the advice! Don't want to do anything on my own, the dealers sometimes give you trouble for touching anything.

Removing the negative battery terminal will not affect your warranty. It is YOUR Jeep after all!

ok so do I just release the latch and take the cable out and wait for a while?

 

[ozgunique]

Ok guys, so I removed the negative battery. Nothing. One night, the car refused to move because the brakes were locked.
The dealership has been working on it for 2 days now, they had to order brake parts and they also found problems with wiring.

They told me this is why you don't buy a new car that has been on the market for a year or two... wow, in that case, don't sell it.
