List of Toyota D4D Probems (Choking, Hard Starting, etc.)

[number001]

What modifications were made in the 2009 up model for Innova to solve the D4-D issue?

They improved the SCV (suction control valve). Made the solenoid longer.

[Jiggs]

It seems sa 2.5D4D lang talga yun me problema..Yung company namin have around 8 Innova and 3Grandia and 2Prado so far yun lang Innova ang nagkaproblem and sobra mausok. In terms of use parehas lang sila. Well I think Prado still not a D4D engine.

First, I don't think all 2005-2008 D4D models of Innova are affected with this chocking problem.
Only for some, kasi kung lahat, then sana lahat nag-reklamo na.
Secondly, kung SCV ang problem then yung nga sana lahat na ng units ay defective.
Though, maybe they found out that replacing the SCV will improve the performance/design of the Innova and get rid of the hard starting or chocking issue per se.
My analysis is that some 2005-08 manufactured Innovas has factory defect (lemon cars).
In a production pov, not all cars are manufactured 100% the same.
Some cars that did not pass the quality test will be reworked and has to go another quality test hanggang pumasa. Question is, baka ito ang mga nakuha ng mga nagrereklamo ng chocking at hard starting? Malalaman ito kung ang Toyota ay aalamin nila ang mga batches ng Innova na may problema. Then they can trace yung history ng production nito.
In consumer electronics, ito yung tinatawag na return to vendor (RTV). Once RTV, the vendor will either rework or scrap the unit, and replace it with new one. A report is also needed and recorded to avoid the same problem in the future.
Kaya importante yung "Lemon Law" kahit may warranty pa ang sasakyan.

Bakit yung Hilux na D4D wala akong naririnig na choking issue? Magka-iba ba ang SCV nila ni Innova?

Saw a recent Hilux at a gas station. Hard starting after a fill up. The owner had been trying for several minutes to no avail.

Drop-side, but new-ish looking. Probably a 2010-2011.

Didn't know if it was a battery issue or fuel pump issue, but I assume it's the fuel pump, since it was daytime and on the highway, so the battery should have been charged pretty well by the time he got to the station.

wala bang lemon law dito satin sa pinas?

kung wala, bat di maipatupad?

Wala bro. Of course ang dahilan nyan e ang lobbying ng mga Car manufacturer's. Madaling kausapin ang mga lawmakers natin eh...

Bakit naghintay pa ang Toyota ng 2009 for that improvement, and hopefully the solution to this issue?...
(Iyon bang 2005-2009 ay denial stage pa?...:twak

Was following a D4D Innova yesterday,- tinapyas na ang bumper na directly above the exhaust,- dahil nangitim na ito (there are traces of it) sa sobrang usok... Its plate starts with Z....

Do you have a photo of what the SCV looks like? and can it be readily seen from the engine compartment? I'll check if the solenoid is already made longer.

on lemon vehicles, afaik, having a factory defect does not automatically mean the vehicle is a lemon. if after several attempts to fix it and the problem persists, then it is a lemon.

Not sure if the web is telling us the truth, common flaws of D4D are the defective injectors even at a few thousand kms drive & the annoying-clattered engines at cold start.
My cousin is always bragging of his 2006 Hilux durability kunu, hasn't miss a beat but my father refute it why, 36K+ kms
only at the clock. hahaha,

[shibby75]

just watch top gear polar challenge. The modified hilux was the first car to reach the magnetic north pole. Wow!

D4d engines really are dependable except when you feed it with crap fuel. Well even humans ran into problem if we eat mcdo for a month.

Cguro may kinalaman din sa paraan ng pag gamit ng sasakyan. Some might use their car more often than the other. The point here is kung na solve ba talaga ang problema ng stalling and choking nung pinalitan na ang SCV to a longer solenoid. In line with this, what is the primary cause of the engine stalling/choking with the original SCV (shorter solenoid)? Is this a design flaw? or a fuel issue?

[SEALANDER]

I guess na solve na ang problema na ito. Wala na naman tayo naririnig na mga reklamo sa mga bagong labas na units (2009-2011). Ang dapat natin tignan ilan ba ang nagkaproblema compared sa total units na nabenta. Nasaan na yung mga forumers na nagkaproblema sa ma units nila?

None for the moment.

[likot]

120,000km na commuter 2010 namin. umaandar pa rin :-) nagchoke lang 1 time pero di na naulit

[Retz]

Is it true that some choking, hard starting problem occured in the 70K up odometer reading? Baka fuel issue na ito ung hindi pa nakapagpalit ng fuel filter kaya clog ang fuel injection pump at hindi na SCV issue.

[number001]

I rode on a '09 GL grandia in Baguio, going around the city there. The driver says no choking or any problems. The unit has done 7x,xxx kms.

I think Toyota has already solve this choking issue sa D4-D.
