1994 Nissan Quest engine complaints
Page 3 of 3: complaints 41 to 56 of 56, newest first, as owners wrote them.
This vehicle has experienced broken bolts on the exhaust manifold. This has caused an exhaust leak which allows fumes to escape into the interior of the vehicle. A survey of other nissan quest owners (93/94) shows this is a common occurence with repairs costing well over 1000 dollars. Nissan has refused to acknowledge this dfect which occurs during vehicle assembly - the exhaust manifold bolts are tightened beyond the recommended torque. User description of these problems can be found at the nissan website on the owner bulletin board.
Engine check light is on intermittently and has been since before 60,000m warranty ran out. Napa nissan failed to diagnose problem--at 52500 mile check they stated that "o2 sensor code" detected, but "o2 sensor okay at this time." I wonder if the exhaust manifold leak may be related to the check engine light?
Manifold on the exhaust replaced 3000 miles ago, now dealer shop is saying the next manifold needs to be replace. Dealer mechanic stated that they have seen alot of the quests coming in with needed repairs on the manifolds and requested that we research on the internet to see what we could find.
We bought the van w/38,000 miles on it and I thought it was a bit loud. Dealer reassured me that most vans were louder than cars. This was our first mini van. Noise kept getting louder with time. I put on new exhaust system to the manifold. It quietened down some. Took it back to muffler shop and they rechecked it and informed me that the engine manifold bolt had sheared off. Said it was a design defect that he saw often in the mercury villagers and nissan quests. When I contacted nissan, they said they had never had any complaints and there were no recalls. This is an expensive repair as the bolts must be bored out. If this is a common problem, why hasn't there been a recall. I have been on your web sight and have seen several complains about this same thing. I had an extended warranty, but wouldn't you know it, by the time we found out what the problem was-the warranty was out. How convenient. I have taken good care of this van, but I won't have another nissan.
Bolts that hold exhaust headers to the block break, and exhaust fumes enter the passenger's compartment. Apparently a common problem and excessivly expensive to repair and ? Whether the same problem will re occur.
Crankshaft broke at 64,314 miles. Engine had to replaced.
The bolts that hold the exhaust pipe onto the manifold broke, causing exhaust to leak from the vehicle. The dealer has repaired the vehicle. The manufacturer has been notified.
A cylinder head bolt snapped, sending part of the washer into the camshaft, seizing it and stripping the timing belt. Upon further inspection, it was determined that a head bolt on the opposite cylinder head had snapped at some time in the past, but caused no damage. Cost of replacing all the bolts and head gaskets, and re-machining the cylinder heads was $1643. We could have replaced the camshafts because the guide pins had been damaged, but the dealer advised against it because the extra cost was of marginal benefit.
Studs broke on left manifold which resulted in warped manifold system. This occurred under normal vehicle use. If not repaired this defect could present a problem of potential exaust fumes in driver/passenger compartment and/or breakage of manifold components dropping in engine while traveling.
Due to corrosion struts on the exhaust manifold system broke off. Could cause engine problems while driving which may result in an accident. Please provide further information.
Rear (firewall) manifold leaking due to being warped and front manifold leaking due to broken stud.
Broken studs on front manifold.
Warped engine manifold due to manifold studs breaking.
Cracked exhaust manifold caused leaks to enter vehicle, resulting in exhaust fumes.
Engine failed and needed to be replaced.
