J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

How to fix a $4,000 hybrid battery problem with vinegar and baking soda

This is one of those 'Don't try this at home if you don't know what you're doing' DIY tales. Two weeks after imgur user "scoodidabop" bought a used Toyota Camry Hybrid with no warranty, he got the Christmas Tree dash display with warnings like "Check VSC System," "Check Hybrid System," and the Check Engine light. After some Internet sleuthing he figured it could be a faulty brake actuator, assuming the hybrid system warning was a false alarm. But it wasn't the actuator, it was the battery, a Toyota dealer telling him that his battery had "gone bad," and he'd need $4,457 to replace it. Then he had a brainstorm: it could be one of the cells that's gone bad, not the whole battery. Scoodidabop has some experience as an electrician, so he figured he could test it and replace any bad cells for about $45 apiece. He removed the battery unit from the trunk and over the course of two hours tested all 68 cells four times. He found nothing wrong. So he devised another type of test and checked every cell again. He couldn't find a problem with any of them. Turns out the problem wasn't in the cells, but with the dirty and corroded copper connectors at the ends of the high-voltage cables. He pulled the 34 connectors and their steel nuts, soaked them in vinegar, gave them a light steel wool scrub, soaked them in baking soda and water to counteract the vinegar, applied an anticorrosive and reinstalled them. That took an hour. When he replaced the battery, the warning lights had all gone out and the battery worked perfectly. Skill level: experience. Cost: less than $10. Perhaps it's time for hybrids to be able to test their own cells individually. Dealers, too.

2021 Toyota Camry AWD vs. midsize all-wheel-drive sedans | How they compare on paper

Just as crossovers have become the dominant body style in the car market, the all-wheel drive they frequently feature has become more popular. In fact, all-wheel drive is so popular that automakers are increasingly putting it in traditional cars. The latest car to add driven wheels is the 2021 Toyota Camry. It will offer all-wheel drive on most of its trim levels, though only with the four-cylinder engine. It isn't alone in this market, though. So we've compiled the Camry's specifications, along with those of a couple of its competitors for comparison. For the purposes of this analysis, we're sticking with the AWD veteran 2020 Subaru Legacy equipped with a naturally aspirated 2.5-liter engine and the relative newcomer 2020 Nissan Altima. Both are similar in pricing and power to Camry. We've skipped the turbocharged Legacy and the turbocharged Ford Fusion with all-wheel drive as both have higher base prices and significantly more power. We'll take a look at these three sedans engine output, fuel economy, pricing and space. Below is a chart with all the raw numbers, and below that is more in-depth discussion of the cars. Performance and Fuel Economy These sedans are very closely matched, but one area where a clear winner emerges is in output. The Camry has a solid 21 horsepower and roughly 10 pound-feet of torque over the Subaru and Nissan. This, despite all of the engines having the same displacement. That power should make it quicker than the approximately 50-pound-heavier Subaru, though the Nissan Altima may stay with it thanks to its curb weight being about 100 pounds less than the Toyota. Also worth noting is that only the Toyota offers a traditional automatic transmission, whereas the Subaru and Nissan rely on CVTs. Subaru and Nissan have both dramatically improved their CVTs to the point they're quite unobtrusive, but if you strongly prefer the feel of softly shifting gears, the Toyota is your choice. In our experience, all three of these sedans are pleasant to drive with suspension and handling clearly tuned in favor of comfort over quickness. Fuel economy is close to a dead heat. Toyota hasn't announced official fuel economy numbers for the all-wheel-drive model, but we can estimate that, as with most all-wheel-drive variants, mileage will be slightly lower than normal models. We're betting it will only about 1 mpg worse than front-drive variants. That puts it in the same 29 to 30 mpg overall range as the Subaru and Nissan.
