Thumbs down Gm/Chervolet Optra Magnum Diesel Pump Failure

This is a known and reported problem by many, here at Team-BHP and other forums.

The car: Optra Magnum

Issue: You drive the car couple of kilometers till it gets warmed up, say 15-20kms and then the car stops!

Solution: Wait 15-20min till the car cools down and drive for another few kilometers! This cycle repeats.

I have done 21000 Kms so far and the car rocks!

My friend's car which has run only 27k in two years has this issue. When reported to the service centre ( Deedi Kollam), they did say its a known issue but since hs car just crossed 2years, they cant replace the part for free. While he was waiting another Optra Magnum came in with same complaint.

What can be done now ? Should I ask him to take the issue up with people at higher level at Chevy?

Clearly its a defect, and ask your friend first to contact the higher authorities.

Its the Manufacturers/Dealer's duty to inform the customers about the defective parts rather than saying 'you are coming after 2 years' of running so we can't do it for free.
If it doesn't solve the purpose Consumer Court is the only option.

Right, if the part was defective then the company should have recalled the affected cars - as several manufacturers have been doing recently.

Escalating to GM should help.

Thanks a lot for your post
I''ve experienced this a couple of times. Whats the way to go with the dealer. Does it happen once in a blue moon or quite often with a bad pump?
Regards

Strange to hear, as the diesel pump is usually a very robust unit, with low chances of failure. I don't remember the pump failing in my Jeep @ 1.4 lakh kms (when the engine did) or even in the 137D that clocked well over 1.5 lakh kms. Amongst more modern cars, I know of a few Mercs, Indicas, Swifts and Innovas that have clocked over 1,00,000 kms and still run the factory diesel pump.

If this is a known problem with the Optra Magnum, and has a high frequency of failure, Chevy MUST replace the defective units for free. Irrespective of whether the car is in warranty or not.

Seems it was for the 2008 set of cars. They have a modified pump for the newer ones.

Talk to your dealer. I have asked my friend to take it up with higher levels.

GTO , these pumps are probably different compared to the inline or rotary fuel injection pumps. What with such high nozzle injection pressure now.
Jkdas I will do that and let you know how it goes. Mine a 2008 May magnum 41K milage. I didn't realise this could be a fuel pump issue like GTO says hence never bothered about it even though it has happened thrice.

It appears to be a fuel pump solenoid issue. Replace the pump solenoid or the pump.

I was doing my research on the Optra Magnum Diesel and came across various posts that mentioned:

1) 2008 cars had a Diesel fuel pump issue.
2) The issue was fixed in the 2009 version.
3) The differentiation is with a sticker on the pump. The 2008 has a Blue sticker while the 2009 has a Yellow sticker.

Just thought about posting this for the junta. What is the cost of a new Diesel pump?

A CR diesel pump varies from a few ten of thousands to a few lakhs based on the manufacturer

Was there a recall or press release from the company about the Pump then.??

Unfortunately, there was no known recall. Although, people who complained / got stuck on the road were given a replacement in warranty. A lot of these reports are on team-bhp itself.

Talk to your dealer. I have asked my friend to take it up with higher levels.

hello, I am planning to buy the optra magnum. I TD the new verna, sx4, vento and the optra magnum today and clearly the optra magnum stands out. I almost made up my mind about the purchase and saw this thread today. Have you heard of diesel pump failure only in the 2008 cars or the newer cars also have the issue?

New cars have new series pumps, so no issues

Mine is a Dec 2009 model, and unfortunately the diesel pump problem came up yesterday. The car failed to start again after stopping at a railway crossing, then started after almost 1 hour gap.

Had given the car to the workshop today morning, just got a call from them saying its a fuel pump issue. The guy is checking if it is covered under warranty (I am pretty sure it will be, hopefully won't have an issue here ). Also, the cost of the pump was mentioned as Rs. 23k by him.

Pretty lucky for me for it to have happened now as the car completes 2 years on the 4th of Jan!!

Apart from this, the magnum has served well. Love it to bits!
