#155 of 3858 Rotten Egg & Poor Fuel Economy
Oct 19, 2002 (2:12 pm)
Since we purchased our 2003 Corolla LE in July, there has been an intermittent rotten egg smell. Took to dealer at 1130 miles. Was told that the new cars had a whole new clean air system and "that just means it's working." Ran MPG test on our own and only got 30.4 MPG. Took back to dealer at 1996 mis. Told them we felt the smell and low MPG were related. Service dept. ran a fuel system diagnosis (and charged for it) and came up with 38.1 at 55MPH and 37.14 at 65MPH. Of course our problem is intermittent and the test ran for .01 mi. Have since run 2 more MPG tests on our own, and only got 35.2 (and that was really babying it) and 32.2. Car is rated at 38 MPG. I am now in the process of communicating with Toyota Motor Sales USA.

this rotten egg smell is a very common theme among new corolla owners right now, and even some camry owners too. Maybe if you try a different dealership, they will be more familiar with it.
jumbieman: I have not noticed this behavior of the cruise, and it may be that yours is malfunctioning...BUT, it is programmed to cancel its set speed if you drop below 25 mph, so if you hit the brakes and go below that speed, you are supposed to have to set the speed again.

My first reaction to the "problems" above is that these are non-issues.
Your fuel consumption figures are right on for a relatively new car, and well within the range of the EPA figures. There is nothing wrong with the car and nothing Toyota needs to do. Our '03 LE automatic ranged from 27-39 mpg, with a suburban average of 30-32, and a highway trip average of 33-37. The only way you are going to exceed 35 mpg consistently is to drive at speeds not exceeding 65 mph [which is how the high figure of the EPA estimates is achieved]. As an OVERALL avg, my usual rule of thumb is about 10-15% over the EPA city figure. If you do better than that, you're ahead of the game. And if you don't have at least 5000 miles on the car, it will continue to get gradually better.
The smell you refer to means you are using a gasoline brand that has an excess of sulfur in it; not unusual depending on where in the country you are, and who is the supplier of the crude that the refinery is using. Switching brands sometimes helps. Where RFG is used [CA, some parts of Oregon, some areas of the NE], this happens less often because the RFG formula calls for reduced sulfur, which incidentally will eventually happen nationwide, though not for a few years yet.
And no, there is absolutely no connection between the smell and your fuel consumption - which, as noted above, is well within the parameters you can expect for this car.
#158 of 3858 improving fuel consumption?
Oct 21, 2002 (11:13 am)
Have others experienced what jrct9454 describes? I keep a complete log of gas mileage and have never had a car improve significantly after a break-in period. My '94 Corolla wagon (5 speed), for example, had averaged 37.2 mpg over the first 1,000 miles and 36.1 mpg over the first 5,000 miles. It averaged 35.5 mpg over the first 9,500 miles, and I just figured that it has averaged 35.0 mpg over 100,400 miles. Similar experience with my other cars.

I hear this from all sorts of folks. Mileage will improve, mileage will improve. I understand the theory behind it, but no car I have ever owned new has had better gas mileage after the first 5K miles...having said that, I have a suspicion that this Matrix is getting slightly better mileage now (maybe 1 point) than it was new (it now has 4000 miles), but I have not been tracking closely enough. Either way it hovers right around 33/37, and yes, I DO stick to the speed limit as a gas-saving measure...
#160 of 3858 No problem...

...with disagreement, and the amount of improvement varies a lot by make and engine. However, most modern engines from Toyota and Honda are not REALLY fully broken in [rings seated, no extra friction points] until somewhere between 4k and 7k miles. Depends on too many variables to go beyond this rule of thumb.
Having said that, measuring fuel consumption can only be done religiously with a log book and a commitment to doing the calculations on every fillup. I do and have always done. If you do, then you've got accurate figures. And NOTHING varies from car to car and driver to driver like fuel use - that's why the EPA tests are just benchmarks. Most people will have a hard time matching the EPA figures [which is where I got my 10-15% over the city number from], and there will be the occasional cotton-foot who can consistently beat the EPA numbers.
An automatic '03 Corolla that averages 30-35 mpg is "in the lane" ... I was merely reacting to the claim that it should somehow be dramatically better.
For a good real-world benchmark, the fuel consumption that Consumer Reports publishes with their road tests has, in my extensive experience, been VERY close to my overall annual average for most cars I've owned [and I've had 50 new cars in the past 37 years].

The chrome lug nuts that come with the aluminum wheel package on '03 Corollas (and perhaps Matrix) are not a one piece unit. The chrome exterior that you see is merely a cap that is glued on to the lug. While having the Firestone recall done several of these caps just came off, no fault of the technician. If they are not damaged, a touch of super glue makes it look new again. I believe I will order real chrome lugs for this car. Every time the tires are rotated it will be the same thing and only a matter of time until one is damaged or lost.
#162 of 3858 Automatic transmission problem
Oct 22, 2002 (8:14 am)
I just bought a 2003 base model Matrix and I've noticed a relatively loud metallic "ping" or "clunk" when shifting from park to reverse. The car drives fine when in gear but I'm concerned about the sound its makes. Unfortunately, it does'nt do it every time I shift so you know when I take it to the dealer it won't "clunk" on cue and they'll look at me like I'm crazy.
Anyone else have the same problem?
Oct 22, 2002 (8:29 am)
are parking on an incline and not setting the parking brake, but just letting the car rest on the 'park' gear, a clunk coming out of park would be perfectly normal.
#164 of 3858 Tranny problem
Oct 22, 2002 (8:58 am)
No. The car is parked on a level surface, parking brake off, brake pedal depressed. Shift from park to reverse. I would characterize the sound as more metallic - like banging two steel rods together. It is very noticeable; not subtle at all. Something is not right.
