Multiple error codes at startup

The past week I have been experiencing some very strange error codes at start up. When I turn it on the ebrake light turns on and it engages, I get a suspension error that says check suspension, and then another 3 letter error that I cant remember. It will go away if I start and stop the car a couple times. I know these cars are super sensitive to a low battery but I just swapped it out this winter. Any other thoughts on what it could be?

If you are just getting the warning just on start-up then maybe load test the battery...I have replaced many "new" batteries....Jason

Yes only at startup but stays on unless I turn car off and on. I will get it load tested, Thanks.

I experienced the same issue a couple of months ago. After driving for an hour, I stopped to grab a cup of coffee and upon restart I get the EPB light and Check Suspension warning light. Driving it felt like the parking brake was on. Pulled over and turned the car off, waited a minute or two, restarted and everything was fine. So far, no more issues. I did decide to hook up a battery tender even though I drive it almost everyday and put on 250 miles. Someone mentioned that an installed "Lo Jack" system could prematurely drain the battery and cause these types of electronic gremlins. I always keep a capacitor type battery jumper in my trunk now.

I had this problem twice a few years ago. My friend, the service manager at Continental Autosports, told me start the car as follows: 1. Turn key to ON position. 2.Wait a few seconds for the Battery Icon in the left gauge to light up. 3.Start the engine. Waiting until the Battery Icon lights gives all the computers time to say "hello" to each other. I now do this as a routine, and have never had another problem.

Just because a battery starts a car or doesn't turn over slowly doesn't mean a battery is good..It can fail and as you start/crank the car the voltage levels in certain modules can get below required levels and this sets the faults.. The quick shot of power by the alternator boost your bad battery and restarting the car and resets the modules..It is like rebooting a laptop...Jason

Battery would be my first guess as well.

You may want to use a Battery Tender on the car everyday. Let us know.

Yup, don't start and crank the car in one key motion. Always turn to on position first, wait for lights to go out then crank the engine. I usually put on my seat belt during that time. The car needs to do some calibration and handshaking. If I don't do that, the throttle is jerky and over-sensitive.


Also make sure the battery is in good condition. I plug in a tender every month or two to make sure it is fully charged. I no longer get ANY strange electrical alerts like MSP, EPB, etc.


Also, if your car is parked and then moved slightly such as when on an incline (rolls slightly as you remove the foot brake), or someone pushed it etc you can get the EPB alert.

Bad Karma. So I used the above method of turning the key to the "On" position and waiting a few seconds before starting the engine and when I turned it off, I have the dreaded radiator fans staying on. Had to disconnect the battery to get them to stop. I think I might have an electrical problem somewhere as my battery is only a couple of months old and I put it on a tender over the weekends. In the year I have had the car, I have experienced the following:

1. "low oil level" warning light when oil is full. Fixed itself after I visited the dealer to scheduled an appointment to fix it.
2. TPMS error - fixed by recalibrating
3. Passenger seat failing to automatically move forward for rear passengers.
4. Passenger mirror down stopped working when reversing.
5. 2 year old battery holding only 350 CA. Replaced a couple of months ago with 900CA AGM battery.
6. EPB and check suspension warning light. Fixed by stopping and restarting vehicle.
7. Radiator fans constantly running. Will be taking to dealer later this week,

You don't need to sit there with the key on to start a car....Electricity travels pretty quick and any communication between the modules is almost instant...Jason

I actually did this start up routine this morning and the problem did not repeat. I had the error about 10 times in a row before that. So would seem like a strange coincidence to just stop now. So it seems like this routine does help, for whatever reason. We will see if this keeps it from happening again until I purchase a new battery.

If the battery is weak then sitting there would probably help some,but it is not how the car was designed...Load check the battery....Jason
