#309 of 318 Battery Replacement
Sep 19, 2012 (3:39 pm)
I purchased my Q45 in June 2005. It now has approx. 73,000 miles. Last week I had to replace my 4th or 5th battery. Replacing this many batteries seems to be abnormal.
Any comments or recommendations?
#310 of 318 94 Q45 heat shield cat converter
Oct 09, 2012 (9:08 am)
HI. I have a 94 Q45 with 116k miles. recently a mechanic removed what he called a heat shield from the under side of the catalytic converter, because it was rattling. It looked like a piece of thin, silver sheet metal. He said it wouldn't matter. Now I have a very hot smell coming from operating the car. I dont see any oil or liquid leaks in engine compartment, and no spots under parked car. Any thoughts? The car otherwise performs very well
#311 of 318 94 Q45 reverse issue

Hi. I have a 94 Q45 with 116k miles. I notice that when I am backing up in reverse the car starts out at normal speed (idling, I am not pushing the accelerator) but quickly slows down and feels like the brakes have been applied. The car operates in reverse no problem, it just seems like the brakes have been activated to slow it down. Is this a normal saftey feature, a brake issue, or a transmission issue? can I safely ignore it?

That heat shield simply protects objects, e.g. grass, from coming in contact with the extremely hot converter and catching fire. Its removal would have nothing to do with that hot smell you are experiencing. My heat shield was missing for years and made no difference.
As for your braking during reversing, I would guess that your parking braking is engaging or failing to disengage.

KSZ, Thank you for the very prompt response. Is it possible that the hot smell may be related to the parking brake not disengaging completly? oh well, enough speculating, time to have it checked out! Hopefully it is one problem causing both issues.

I own a 2005 Q45 with 72,000 miles. Approx. 3 weeks ago when I tried to crank the engine I only got a "click" sound for about four attempts then the engine starts without problem. This has happened once or twice over the past three or four weeks.
Also, I have had to replace the battery four or five times since I bought the auto. The current battery is about two months old. Need comments, recommendations or suggestions

Assuming your battery is OK, I would check the inside of the battery cables. Take a fine grit sandpaper and clean the inside of the cables thoroughly and securely attach to the terminals. For good measure, just rough up the terminals with the same sandpaper.

The first thing I would do is find you local Autozone or Advance auto parts store, depending on your area, and have them check the battery, charging system, and starter. Problem sounds like it could be in the starter solenoid, or brushes. Troubleshooting is best when you start with the basics and work your way out.
