I drive a 2010 Toyota Prius. From top to bottom, I’m thoroughly impressed by the technology in this car. And yet this engineering marvel is so easily disabled by its inferior owner leaving a dome light on overnight and draining the 12V battery.

Is there any technical reason cars allow the 12V battery to be drained down beyond the point where the car will start? Who needs that extra 6 hours of dome lighting?

Sajeev, I wonder if you wouldn’t be able to offer some of your wisdom on the continuing saga of the van.

The new automatic went in and worked perfectly. The engine got fully rebuilt. New crate short block direct from Toyota, heads rebuilt-surfaced/valve job/adjusted/stem seals. Entire engine re-gasketed with Toyota FIPG/OEM gaskets. New pretty much everything else on the front of the car. Wires, plugs, all three O2 sensors (Denso), IAC, Coolant Temp sensor, MAF, resealed injectors, OEM fuel filter. Brand new main TWC catalytic converter. Converted both the exhaust manifolds to 1998 Sienna California emissions spec (integrated warm-up cats), so now the car has a total of THREE catalytic converters.

Broke in the entire setup for 1,000 miles the proper way with varying RPMs, letting off gas to allow rings to seat, and occasional three-quarter throttle bursts, special break in oil for the first 500, then over to Mobil1. Tons of power, smooth, quiet. At idle she is so smooth you can’t even tell the van is on. Checked the entirety of the engine for vacuum leaks — nothing. Compression is strong across the board. Zero blow by.

However, I live in California, and — you guessed it — the van still failed the smog check. (Read More…)

2015 Volkswagen Golf TDI white

Scott writes:

Sajeev,

I’ve got a two-year-old 2015 Golf with a scarred rear bumper after an encounter with a stone wall (lesson learned — use the mirrors to complement the fuzzy nighttime camera image). Two repair estimates for refinishing the bumper cover average $525.00. The damage is down low behind the rear wheel and I can live with the gouge, for now.

However, I’m wondering about being gouged later when I inevitably decide to trade the car in (probably a few years). My question is: Fix it now, fix it before I sell the car, or don’t worry about it and roll the dice on what a dealer will ding me at trade-in time? (Read More…)

2017 Fiat 124 Spider

Sajeev,

I asked Bark for advice a few months ago and this question is somewhat related: I’m now planning to get a Miata or maybe the Fiat 124. I live at 5,000 feet above sea level and from what I’ve read, it sounds like the average naturally aspirated engine loses 3 percent of its power for every 1,000 ft increase in elevation, which translates to a 15 percent power loss at 5,000 ft. However, it appears that turbo engines do not suffer as much, as they lose about 1.5 percent power per 1,000 ft on average due to the less dense air. (i.e. more dense with forced induction – SM)

If that is the case, than I expect it would be better for me to get a turbo engine — provided I’m okay with the Fiat. (Read More…)

This isn’t the first time you’ve seen the Ford GT Welcome Guide on the Internet, but this is the first time you’ve read color commentary from a renowned journalist autoblogger connected to a GT purchase via his brother’s future acquisition. (Read More…)

I have a W203 Mercedes-Benz C 230K/1.8L. Would a rear-drive GM DOHC 3.4-liter V6 with a turbo make the 300-plus horsepower I think this car needs? Would an LS V8 fit? Would a 392 Dodge Hemi fit? Unless AMG, even the Mercedes-Benz V12 is only 5.0-liters. My car has the six-speed found in manual transmission Camaros.

Thanks!

Torque Pro Fault Codes

Hi Sajeev,

I’ve been reading your postings for years and decided to actually share my (maddening) issues with you.

I have a 2006 Mazda3 S five-door (five-speed manual, 2.3-liter) that I purchased new in December 2005. It only has 101,000 miles on the clock but has had a few significant problems along the way despite regular maintenance. However, the most recent issue has me stumped.

ND Mazda MX-5 Miata Closeup, Image: © 2016 Sajeev Mehta/The Truth About Cars

I had the distinct non-privilege of sampling an ND Miata at a Mazda event for the general public, which was also covered by one of TTAC’s sister publications. A gaze at the hood bulges at (slow) auto journo track speeds netted a surprise: there was an urgency to get this cab-backward profile on the Vellum.

It’s no different than being a design student; visions quickly sketched on vellum (lower case) were crucial. Today’s urgency isn’t for my GPA, but for Vellum Venom’s readers (all 51 of you) and for my soul. It’s been too long.

Hi Sajeev,

I bought my 2008 Ford Fusion V6 AWD about two years ago from a Ford dealer. At the time, it had about 65,000 miles. I’m now at 85,000 miles. I also bought the three-year extended warranty (one year left).

Despite my usual aversion to buying extended warranties, it’s proven to be a sound investment. I’ve had a few things (including an oil leak) fixed for free (minus deductible). The warranty has already paid for itself. The dealer I used for the warranty service (not the purchasing dealer) gave me a few free oil changes and some credit on an account, so I’ve been going there for routine oil changes/tire rotations.

At the last oil change/tire rotation, I noticed they didn’t check the transmission fluid. I asked them to do so. The technician checked the fluid: it was at the correct level, but getting dirty. I asked if I should change it and he mumbled, “If you don’t do it now, don’t ever do it. Transmissions get used to the fluid and replacing it might ruin the transmission.”

I’ve noticed various new-ish cars, ranging from Kias to Lincolns, with a flash-then-steady mode on their center high-mount stop lights. Is this becoming standard? I expect it’s not federally mandated, but I can’t imagine where else it’s coming from.

More importantly, how is it being implemented? I’m thinking about grabbing one from a salvage yard in a few years.
