Standard car powertrain warranties–what do they cover?

September 22nd, 2009

For the 2007 model year General Motors (GM) increased the powertrain warranty on its cars to five years or 100,000 miles (5/100), whichever comes first. They felt this warranty was better than Hyundai’s 10/100 powertrain warranty because it transfers to subsequent owners of the car.

Today GM sent a memo to dealers to announce changes to the items covered by the 5/100 powertrain warranty for 2010 model year cars.

Items that are no longer covered include:

1. Fuel system, including fuel pump and fuel injectors

2. Powertrain control modules

3. Throttle body assembly

4. Clutch and pressure plate for manual transmissions

5. Wheel bearings

Items added:

1. Oil lines and oil cooler

2. Crankshaft pulley

3. Clutch master cylinder

First thought: they’re reducing coverage, which isn’t good. The fuel system and wheel bearings are among the powertrain items most likely to fail in the first five years.

Second thought: do competitors’ standard powertrain warranties include these items?

To find out, I called a few dealers and had them check coverage on these items for me. (Note: I did not ask about the crankshaft pulley.)

First off, the powertrain control modules tend to be covered under the 8/80 emissions warranty, and this remains the case with GM.

Beyond this, it turns out that the items covered under the standard powertrain warranty vary quite a bit from manufacturer to manufacturer.

Toyota covers everything in the list except the throttle body assembly.

Honda covers the fuel pump and drive wheel bearings, but nothing else on the list.

Subaru covers the transmission control unit and the wheel bearings.

Hyundai covers only the drive wheel bearings with its non-transferable 10/100 powertrain warranty.

Nissan covers nothing on the list.

Still waiting to hear on Ford.

In other words, it appears that GM’s coverage used to be among the best, perhaps even the best, and will now be among the worst–but that it has plenty of company there.

GM’s 60-day guarantee

September 15th, 2009

So, GM is going to allow car buyers to return a car in the second month of ownership for a refund.

Or, buyers can opt for an extra $500 rebate instead.

So, how many people are going to forego $500 for the right to return the car?

The fine print, as I understand it:

1. Dealer processing and titling fees are not refundable. Sales tax is.

2. The car must have less than 4,000 miles on it.

3. The car must have at most $200 in wear and tear or damage.

4. Only one return per household.

My wife is still upset that I returned a partially eaten loaf of bread to CostCo. (My argument then: no one liked how it tasted. What’s a satisfaction guarantee for?)

So I’m guessing she won’t let me buy a Corvette Z06 unless I intend to keep it. And if I intended to keep it, I’d opt for the $500 rebate.

Or maybe GM really does believe in its products. A friend of mine once bought a big screen TV right before hosting a Super Bowl party, planning to return it the following week. But, after having that TV in his living room, he couldn’t bring himself to return it.

Maybe GM figures that anyone who bought a GM car planning to return it would find that they couldn’t live without the car?

2010 Kia Soul — few repairs so far

September 8th, 2009

We’ve updated the Car Reliability Survey results to include owner experiences through June 2009. With this update, our results are about 14 months ahead of the traditional source of such information.

2010 Kia Soul exteriorPrompt quarterly updates enable TrueDelta to provide initial reliability stats on new models quickly. The August results included the first 2010 model, the Kia Soul. (A big thanks to Kia Soul Forums for helping to get the word out.) Launching an all-new model can be tricky, but so far it appears that Kia has done well with this one. Through the end of June only one of the 38 participating owners had had a repair, to the satellite radio. This works out to 15 successful repair trips per 100 cars per year.

When the stat is updated again in November, it will probably be a bit higher. For July some owners reported repairs to the optional lights on the speakers that beat in time with the music. Kia is aware of this problem, and has issued a TSB for it, so it should only affect early cars.

The November update will include additional 2010s such as the redesigned Mazda3 and Toyota Prius.

Sign of the times: the 2010 Mazda CX-7 gets a non-turbo four

September 5th, 2009

Though fuel prices have moderated, as long as the economy remains soft car buyers will be focusing on fuel economy, not horsepower. In response, manufacturers are rushing to offer at least the alternative of a less powerful, more efficient engine.

The Mazda CX-7, a compact SUV, is a case in point. When the CX-7 was introduced three years ago, only one engine was offered: a 244-horsepower turbocharged 2.3-liter four. A good fit for Mazda’s driver-oriented image, but fuel economy has been a weak spot.

For 2010 Mazda has refreshed the CX-7, and the turbo has been joined by a 161-horsepower non-turbo 2.5-liter four. The new engine is good for EPA ratings of 20 city and 28 highway, compared to 17 and 23 for the 2009 turbo. (For 2010 the turbo improves to 18/25.) The new base model weighs 300 pounds less, so acceleration should be similar to that of the non-turbo fours in the Honda CR-V (20/27) and Toyota RAV4 (22/28).

Why Toyota is not the new GM

August 31st, 2009

They automotive press is increasingly fond of claiming that Toyota is going down the same path GM went down. But words are cheap.

Did Toyota overexpand their production capacity just in time for a severe market downturn? Absolutely. But a single major strategic miscue does not inevitably lead to long-term decline.

The real thing to pay attention to is not Toyota’s current profitability, but how they react to their problems.

First off, do they react to problems by claiming that they aren’t really problems, or by attempting to fix them? GM has for decades tended to opt for the former. Toyota, in contrast, readily admitted that it had made some mistakes and that it needed to fix these ASAP.

Second, if a solution doesn’t work, do they give up, or make another attempt? GM, time and time again, has poured billions of dollars into “breakthrough” solutions, only to ball them up (or let them die on the vine) when these solutions don’t initially succeed. Toyota, in contrast, has a record of trying over and over. They’re on their third Lexus GS, for example. Keep at it, and they’ll eventually have one that wins over BMW owners.

The key isn’t avoiding mistakes, but learning from mistakes, and not giving up. So far, Toyota seems to still be learning, and persisting. So I do not believe it will go down GM’s path.

A 230 MPG EPA rating for the Chevrolet Volt

August 11th, 2009

Back in September 2008 I suggested how gas mileage should be calculated for range-extended electric vehicles like the upcoming Chevrolet Volt: one set of numbers for electric use, and a second set for after the batteries have discharged. General Motors, of course, saw things differently. It wanted the highest possible numbers, both for CAFE and for advertising purposes. And it appears that GM has gotten its way, as the EPA city rating for the Volt will be 230 MPG.

How is this possible? Through a test that makes almost no use of the gasoline engine. Problem is, this figure doesn’t remotely represent the full cost of operating the vehicle.

In a way, though, such a high number will be less misleading. General Motors has so overshot the mark in lobbying for the highest possible number that even the most clueless person will know it’s BS. If they’d finagled a number in the 80 to 100 range then perhaps the average person might have been misled into thinking it was real. But not now.

Is it fair to rate luxury car reliability on the same scale?

August 9th, 2009

A new blog for the Land Rover Freelander charges that it’s not fair to rate the Freelander’s reliability using the same scale for all cars. The two reasons given: luxury car buyers are pickier, and luxury cars have more features.

It might or might not be true that luxury car buyers are pickier. Many people have suggested this, but I’ve never seen any data on it. One thing TrueDelta does to reduce the impact of the pickiness factor: we measure the number of successful repair trips, not the number of perceived problems.

It is certainly true that luxury cars include more parts that can break. But also note that here we report the actual repair frequencies, and not just “better than average” or “worse than average.” If a luxury model requires more repairs because it has more things that can break, then that’s just the facts. People want to know how often a model is likely to require repairs, not some stat adjusted for the number of things that can break.

The larger problem with the post: people aren’t usually going to compare the scores for a Land Rover to those of a Honda, then opt for the Honda. Instead, people considering a Land Rover are likely to compare its scores to those for competing luxury models.

Which brings us to the outright error in the post. It asserts that “other luxury brands like Mercedes-Benz, Rolls-Royce, and even Lexus also get a bad rap.” Sorry, but this just isn’t true. I’ve never seen a reliability stat for Rolls-Royce, so it seems that the author wasn’t looking at actual results when writing the post. Yet more evidence of this: unlike the larger LR3, the LR2 (Freelander2 in the UK) actually has a fairly low reported repair frequency in TrueDelta’s results. Then there’s Lexus. The great majority of Lexus models have received above average reliability scores, even when measured on the same scale as Civics and Corollas. It is more difficult to achieve top scores with a luxury model, but it is nevertheless possible.

July is finally over. Well, almost.

August 5th, 2009

The survey covering June ended today. July was not an easy month. The response rate was running two to three percent below the norm for much of the month. Not good, as this would have nearly cancelled out all of the people who joined in the last three months. And I’m not much for running unless it gets me somewhere.

Then, toward the end of the month, we ran a special email asking members why they hadn’t responded.

The #1 reason: the car had been sold. And so we learned that we need a more obvious way for people to report when they buy and sell cars.

Thanks largely to that email, we ended the month with over 12,000 responses, and a response rate a few tenths above the norm. Quite a comeback.

The payoff: 257 full results, and another 249 partial results, in mid-August. Including the first for a 2010 model.

Ten other models fell a single response short of the minimum. A late response might still tip them in.

Results won’t be out before mid-August because I’ve still got a lot of data to clean. When that’s done, July will finally be over. And we can then start looking forward to October…

The price of Ford’s EcoBoost

July 20th, 2009

Ford has now announced the prices of the 2010 Fords and Lincolns equipped with its 355 to 365 horsepower “EcoBoost” 3.5-liter turbocharged V6. At one point Ford said EcoBoost would add $750 to the cost of an engine. But perhaps they were comparing the EcoBoost engine to the one it took the place of, a V8 in this case.

As it happens, EcoBoost adds $3,000 to the price of a Flex AWD and MKT AWD, and $5,000 to a Lincoln MKS AWD. In all three cases, about $200 can be attributed to the manually-shiftable automatic with shift paddles. With the MKS, the Ecoboost’s price bump also includes larger wheels that cost $510 on the non-turbo MKS.

Still, EcoBoost clearly costs more with the MKS. Why?

In comparison, the price bump on the Flex and MKT seems reasonable. But there’s one big problem: I recently drove a regular Flex for 2,500 miles, and the regular 262-horsepower V6 felt more than adequate. This just isn’t the sort of vehicle that tends to be driven aggressively. If I was driving in the mountains or towing a trailer, then the EcoBoost would probably be much more necessary.
