I looked at the Prius Plug-in in the current issue of Consumer Reports, which is its annual car issue. Several "observations": The 2013 model was given the next to lowest reliability rating (half-black circle), while the 2012 was given the highest rating (solid red circle), and the 2013 was therefore on its "avoid these models" list. What the ....??? These two models are identical, so how could there be such a difference in their reliability??? Looking at the rating, I would expect to see 2013 models dead on the side of the road, or living in repair garages. When was the last time someone in this forum had a repair issue? Yes, there have been gripes about the nav system in the Base, but the gripes were about its designed features, not that it broke and needed repair. Something is really screwy here. They gave the PiP a 43 mpg combined rating in HV mode. How does one drive a PiP and only get 43 mpg in HV mode? Like a NASCAR driver on a race track? My wife is lead foot and gets 50+ mpg without charging in combined city and highway driving. And they gave the regular Prius 44 mpg. But everyone here reports the PiP getting 10-15% better mileage in HV mode than the standard Prius, mainly due to the more efficient regeneration. Oh, well... One of the "lows" stated for the PiP was "not purely electric in EV mode". That would be legitimate gripe if the PiP was an EV. But it is an enhanced hybrid, designed for low emissions and energy efficiency; absolute avoidance of using the ICE was not one of its design objectives, as it was for range-enhanced EVs like the Volt. It uses the ICE when that is the best power source, and the battery when it is the best power source.
Some body with big money is paying the writer of the article or the writer is an uneducated Hybrid technology boner.
It's due to the low relative sample of 2013 owners responding to the CR surveys. If only 2 people respond to the survey and one of them had a mechanical issue- the car has a 50% trouble rate. If 100 people responded and 2 had issues, the car has a 2% trouble rate. It's all in the numbers... How many miles did they drive and what was the outside temperature? I can get 43 mpg in my PIP on a frigid 18 deg morning for the first few miles when the ICE automatically fires up without me calling for it. Us PIP owners in cold areas know this fact all too well.
I'm prepared to believe that no-one at CR is seriously on the take, as their entire reputation is based on this. No argument with your other possibility, though.
Agreeing. I think the questions with respect to CR are mainly about the validity of their ratings, as opposed to their integrity. Arthur Andersen, a major financial auditing company, simply went out business a few years back when their integrity was compromised in the Enron scandal. Same thing would happen to CR.
At the same time, they gave the Prius 2014 the Green Car of the Year award, based partly on reliability.
I can't think of a reason the 2013 would be different, and even if it was, you'd be under warranty on it.
I tend to think NY Rob has the most likely explanation; lack of sufficient sample size. Since CR makes heavy use of statistics, I would have thought they would be experts in this area and only report their findings given appropriate sample sizes though. Regarding the low MPG figures... I have always imagined they do their efficiency tests by hiring a Formula 1 driver to race it to the top of Pikes Peak as quickly as possible. I'd never be able to get as poor economy as they list for any vehicle unless it had a fuel leak. Disregard any figure they post regarding fuel economy, but use their comments as a relative measure against other cars they have tested (raced?).
FWIW- it was 16f here this morning- my first five miles in EV mode got me 43mpg. By the time I got to work (total 28 mile drive) I was up to 66mpg. Just saying....
10 degrees here my 93 miles drive to my shore house, on the Garden State Parkway at 65-68 mph on CC in all HV, got me 53 MPG
Who reads Consumer Reports? They got the "C" wrong, and now the PIP! I would never place much weight on their survey, something does not add up with them.
Tesla owners love their cars, so if one is for sale, it may well be problematic. As for CR, I consult them before the car magazines, which are even less objective, and have a proven track record (so to speak) of picking Losers. There should be a concerted effort to get CR to reveal (and then revise) their testing methodology and statistical analysis.
I sent this to the Consumer Reports editor. In the issue on autos you state that when operating the Prius Plug-in in the full EV mode you found that it often "fell" out of the EV mode when accelerating. Yes, I have had the problem as well. I've owned my Prius Plug-in for almost exactly a year and driven it over 8500 miles. About 3500 of those miles were in the full EV mode. The car fell out of the EV mode exactly twice. That is just terrible, once maybe I could live with but twice, that is just unacceptable. Perhaps if you tested the car as a gas-saving plug-in instead of a hot rod you would have found different results.
Are you sure that they will understand where you intended to be sarcastic? They might consider your letter another reliability complaint.
As long as English is the primary language of the person who reads the message, the last sentence says it all
It's a shame that cars get tested as either fetish objects or appliances, with little or nothing in between.
