With the cold weather upon us, has anyone noticed any rough starts with your RDX? I have noticed 2 so far. The first time the engine just kept cranking and i thought ok now what.... not like I can just take a key out to stop it from cranking with push button start. It finally stopped after about 10 seconds

The second time the start was hard and the engine barely took over. My RDX has about 450 miles on it right now


I havent had a chance to check out the battery and see the cold cranking amp rating but I have always used optima yellow top batteries with no worries. Those batteries seem to work better in cars that are technology packed like the rdx. Starting has always been solid with those batteries


Thinking about switching the oem battery out with the optima. But if I keep having hard starts im taking it to the dealer first to get checked out

 

Define cold weather. The daytime highs have averaged in the -22C (-8F) range here and I haven't experienced any hard start issues.

 

Does the battery not turn the motor over fast enough? If it's turning over just as fast as before it obviously has nothing to do with your battery. It's probably an electronic or fuel error. Have your dealer look into it.

 

If you look all over acurazine (regardless of model), you will find people complaining about the stock batteries. They must suck from the factory or they discharge very quickly during transport.

The good news is the battery is covered for 4years---go see your dealer.

 

25-35F

well i purchased the car when the weather was between 60-70F degrees and the starts were pretty solid, crank time was quick and turnover was solid. Now that the weather has gone below 35 degrees along with a couple days of rain, starting has not been as solid as it was before. Crank time is actually a little longer and one instance the car did not start at all. Almost seemed like there wasnt enough juice to turn over. I waited a little bit, and the car started the second time. I had the car for almost 2 weeks now

 

CCA is 540 I believe

 

If you are having battery problems with a new (or newer) vehicle it could be a defective battery or it may be an improperly done vehicle preparation from your dealerships servicing technician. See what they are supposed to be doing below. Are the battery codes entered under the hood and in your maintenance book?

Check the Battery

To ensure long battery life and that the client receives a
fully charged battery, the battery must be checked in
these instances:
• When the vehicle first arrives at the dealership
• During the TQI (if done at a later time)
• During regular intervals
• Just before delivering the vehicle to the client
Test the battery with the ED-18 battery tester, using the
instructions in Service Bulletin 88-016,

GR8 DIAGNOSTIC NEEDED

down the code in the “Final Inspection (At Delivery)”
section.

Wow, 25-35F isn't cold at all. Your battery probably isn't an issue - since it's turning the starter just fine. I'd recommend taking the RDX to your dealer a.s.a.p. - to diagnose tuning, electronic ignition, fuel injection issues.

In my local temps under 20F, I've had no starting problems.

 

Though not as cold as some of your area, I have no problem starting it @29-32 degree in DC/MD/VA area.
