car   Power Assist Brake problem of Chrysler Town & Country

The car is a 1997 Chrysler town and country. Crash was involved with this problem. Having owned maney cars and trucks since 1965 I feel these brakes are the worse ones I have owned to date and feel that they were resonsible for the accident. The brakes require too much foot pressure to apply. I have driven other Chrysler vans, and feel it is the 1996 and above model year that have the greatly increased foot pressure requirments to stop. It seems like the vacuum booster is too small. The 1994 Dodge minivan we vanpool to work in has far better brakes in terms of brake power to foot pressure response. I have driven several different ones at the dealers and it seems to just be the late models that are efected. It requires too much foot pressure for a small person during a panic stop. Regular braking seems to be ok, but I would prefer a lighter pedal. This power assist brake issue occurred Wednesday, Mar. 25, 1998.

Acura refused to run a computer check on the car or to send anyone from California to inspect the car. The dealer service center had initially told me that they would have someone from California come to inspect the brakes after the accident. They told me that they checked the brakes by driving the car and that they were okay. They repeatedly told me that they would not do any further tests pertinent to my complaint unless the car insurance company requested that this be done. I spoke with several people at metlife, (our insurance company), and they told me that they do not make such requests. We should ask the manufacturer to run further testing. I again spoke with Acura service and the customer service center in California ,(on several occasions), and was told they would not run any further testing of the brakes. They again stated that the brakes were fine, and that we should pick up the vehicle. To date, we have not picked up the vehicle because we are afraid that the vehicle is not safe to drive. The dealer has had the car sent to an auto body shop. This car is a leased vehicle. Repeatedly I asked for a written report regarding what was checked and found with brakes failures in these occasions, but no answer was received from Acura.

car   Power Assist Brake problem of Mazda Tribute

The vehicle is a 2001 Mazda Tribute. VIN of the vehicle was 4F2CU08131_. Engine periodically shuts down at low rpms. Power steering and power brakes fail when engine shuts down and, as a result, the Tribute is difficult to steer and stop. Shutdowns have happened at least eleven times - always at low rpms (1000 rpm or less). Each shut down occurred when I was coasting downhill. Generally, I was also braking at the same time. The dealership's service department has been extremely diligent in their efforts but so far Mazda has been unable to provide the technical assistance needed to resolve the problem. I bought the Tribute in Jan 2001 and expericed the first failures before the first 3000 mile servicing. The first dealer resolution attempt was not documented. The technician queried the onboard computer but there was no code indicating any failure. On 4/28/02, after more failures, the problem was diagnosed as a wiring problem and "fixed". Three more falilures occurred before the Tribute reached 6000 miles. The dealer could not duplicate but on 8/8/01 advised Mazda. No repairs were made. Engine shutdowns continued and on 10/09/01 at 7,639 miles, the dealer removed the bypass air control valve and cleaned the passageway - as advised by Mazda technical assistance. The Tribute then ran fine for eight months. Then in June 2002, the problem reoccurred and the dealer was contacted. Dealer still had seen nothing further from Mazda concerning resolution of the problem and contacted them once more for assistance. Suggestion was to "re-program" the onboard computer the next time the car is brought in for servicing. This is a dangerous situation and will utlimately result in an accident. So far, shutdowns have occurred while I was in an uncongested area but that is simply luck. Mazda and Ford have a really dangerous situation that needs immediate attention and resolution. So far I have received nothing from Mazda letting me know there is a problem with the Tribute. Guess they feel it is not a problem as long as it can be ignored.

car   Power Assist Brake problem of Nissan Titan

The VIN of this vehicle was 1N6AA07A94_. No accident or injury as of yet. However, I have been experiencing brake judder issues on my 2004 Nissan Titan evry 3000 to 5000 miles. I currently have 10,900 miles on the truck, and have just brought it back to the dealer for the third time for repair of this issue. Judjing from my experience, and that of other Titan owners, it is reasonably clear to me that we are dealing with an inferior design of the brake system on this truck and it is only a matter of time before someone is killed. This is a problem that Nissan has been dealing with for months now, but with no good resolution. It has even been rumored from a very reliable source at Nissan, that the problem extends back to a misplaced purchase order for hundreds of thousands of the brake parts. Rather than order the right parts, and delay shipment, Nissan has elected to build the trucks and deal with the problem later. I hope that there can be some kind of investigation into this problem, with the outcome being a forced recall (not just a TSB). This power assist brake problem happened on Wed., Jan. 26, 2005.

The car involved was a 2008 Saturn Sky. Our Saturn 2008 Sky redline has a brake problem that my wife was complaining about every time she starts it up after it has had time to cool down. The brakes do not work properly. I tried it and found that the car can move while holding down on the brake. If you don't pump it it will not stop. I took it to the dealer today and was given a notification from the dealer service writer stating this was normal. They did take the car to check it out after I insisted. I don't care what they think is normal if I can't stop the car there is a problem. I then checked on line to see if any other Sky owners were having the same type of problems. And I guess you know what is going on. This is to go on record with you that the car is not safe as is. I am concerned that this may lead to a problem during operation at speed and kill us. This needs to be dealt with now and and nat after someone dies. Our car has gotten worse over the last month since the temperature has gone down. Or it is just getting worse. This problem occurred on December 11, 2007.

car   Power Assist Brake problem of Subaru Outback

The vehicle involved is a 1997 Subaru Outback. The vehicle identification number (VIN) of the car was 4S3BG6857V_. Power brakes fail to function immediately and shortly after (within about 5 minutes) after cold start in temperatures below 10 degrees f. Brake pedal remains high and stiff with little to no travel distance indicating no power to power brake system but brake pedal apparently travels enough distance to allow shifting out of park. User remedy is to allow more than 5 minutes to warm and verify brake pedal travels normal distance indicating power brake system is functioning before shifting out of park. Other remedy is to sharply depress brake pedal several times until the brake pedal travels normal distance indicating power brake system is functioning before shifting our of park. This remedy works fine for me when I remember to follow this procedure during temperature below 10 degrees f. Other family members that do not drive my vehicle as often as I do are prone to forgetting to follow the remedy procedure. For anyone, including myself, that is either unaware of this defect in vehicles operation or forgets to follow the remedy procedure finds them self in a very surprising situation if traveling at a speed to fast to allow for braking with a failed power brake system. I have actually noticed this problem for the first time during the winter of 2002 - 2003 and have noticed this once again this winter with the recent onset of frigid weather here in the northeast portion of massachusetts. I have yet to bring my vehicle in for specific service on this matter, however, I do plan to contact a local Subaru dealer for assistance. This issue happened on Wednesday, January 14, 2004.

car   Power Assist Brake problem of Volkswagen Passat

Vehicle identification number (VIN): WVWVD63B22_. The brake booster on my 2002 Volkswagen Passat started acting up in freezing weather on numerous occasions. When this happened, I lost all power assist for the brakes and braking performance was severely degraded. On several occasions this also led, for reasons unknown to me, to the front brakes locking up, immobilizing the vehicle. The problem was eventually fixed by the Volkswagen dealer, who replaced the brake booster unit under warranty. I think there is a class problem with the brake booster system in at least 2002 Passats and no effort has been made by Volkswagen of America (voa) to communicate this to owners of these vehicles. I learned from the dealer that they had experienced many similar instances with the brake booster system on Passats. If not a formal recall, at least some communication to owners from Volkswagen should be forced as this is serious safety issue. I have talked to voa customer service by phone and their response was that they do not issue voluntary recalls. This is done, according to the voa rep, only when ordered by the government. If true, this seems a sad commentary. So I am working this issue through NHTSA asd my only recourse. It was 01/03/05 when this power assist brake issue occurred.

car   Power Assist Brake problem of Audi A4

12/2004, purchased certified 2001 Audi A4 from beechmont Audi in cincinnati, ohio. Car had a comprehensive 300+ point inspection performed by Audi as per paperwork. 5/20/2001, vehicle taken to bluegrass Audi in louisville, kentucky for a brake assist problem. Several days prior to brining the vehicle in, I was in reverse leaving my garage when I found that I needed to push the brake pedal to the floor to slow and stop the vehicle. I noticed when I drove forward the problem went away. I tried backing up again and found the braking to be normal. Later that afternoon I was going to lunch and when I backed up the vehicle didn't have any brake assist again and I had to push on the brake pedal with maximum force. Took the vehicle to my local Audi dealership and was told by the service manager that the car needed a brake flush. They performed the brake flush, but that didn't fix the problem. I returned the vehicle back to Audi several days later and was informed that they found the problem with a grommet that connects two vacuum hoses at the bulkhead. They added a clamp to stop the air from escaping the system, but the next day it proved not to work. They also informed me that the brake pads and rotors were within Audi limits. Took the vehicle back and was informed that they needed to replace the grommet. After the item was replaced, it still has the same problem as of 7/4/2005. In summary, the vehicle has a brake assist problem in reverse after the vehicle has been sitting for a short period of time. In my un-scientific research, the brake assist fails if the vehicle has been sitting and not running for less than 2-3 hours. When this occurs, the brakes operate, but maximum brake pressure is required to stop the vehicle until the pressure builds up. This could be an isolated incident, but I thought I would pass this information along just in case there are others with the same problem. It was 05/16/05 when this power assist brake issue happened.

car   Power Assist Brake problem of Buick Lesabre

The vehicle is a 2000 Buick Lesabre. Owner noted unusual sound when applying brake pedal in a hard, but not panic, stop. Investigation revealed that the power brake booster was extending out 1 inch from firewall when hard brake pedal pressure was applied. Brakes functioned normally. Further investigation revealed that the four studs which secure the brake booster to the firewall were not tightened properly. The four nuts which secure the four booster studs to the firewall were only engaged the length of the nut, leaving about 1 inch of the stud thread exposed. Owner fastened three of the four nuts, since the fourth stud was obscured by the steering column. The fourth nut will be referred to the dealer for repair during the next scheduled maintenance. Brakes now function ok without noise or booster movement, but this failure to properly assemble the booster to the firewall could have caused loss of brakes if the four nuts had totally disengaged from the booster studs. This problem occurred on Friday, Sep. 10, 1999.

car   Power Assist Brake problem of Cadillac SRX

2005 Cadillac Srx. Consumer writes in regards to vehicle jerking,bucking and stalling while driving. The consumer stated he discovered the problem was with the brakes. Apparently, the vehicle has five different systems that can work the brakes automatically, and it seemed one of them was working harder than normal. The consumer stated he was always taught to press on the brake pedal three or four times when making a full stop, so the brakes would not heat up or wear out prematurely. However, he believed the vehicle was interpreting his way as a panic stop. When he applied the brake only once, without letting off the brake all the way to a full stop, there was no bucking. The consumer believed the panic brake assist system , was only one of the five brake assist systems that he believed could stop the vehicle immediately, as it did the previous week. It was 03/01/2013 when this power assist brake issue happened.

car   Power Assist Brake problem of Cadillac Escalade

The vehicle is a 2002 Cadillac Escalade. During a u-turn, on a 4-lane street the power steering and brakes stopped working. I wasn't able to steer or stop. The steering became very hard as well as the brake pedal. The Cadillac dealer suggested it was the power steering pump and changed it under my warranty. I picked the car up 1 week later after being told that my car was fixed. After leaving the dealer, I stopped at a traffic light and my break pedal began vibrating and again I was not able to steer the car. I took the car back to the dealer and allowed him to talk me into keeping the car for the weekend (it was a Friday and no mechanics worked the weekend). Again I left the dealer and carefully attempted to drive the car home. I was stopped behind a car making a left turn and as I attempted to remove myself from behind the car by changing lanes, I realized that the car will not turn unless moving. I went back to the dealer and demanded that they keep the car until fixed. One week later (the following Friday) I was called to pick up my car again. I was told that the new power steering pump was bad and they had replaced it with another new one. This time the steering wheel was jerky, and the brakes vibrated a little less than before. In addition, the battery light was blinking on and off and the charge was at appx. 9 volts. I left the car again. The next Friday I picked up my car and was able to drive it for about a week and a half all the while knowing that it still wasn't right. This time the steering was less jerky (but jerky nevertheless) while applying the brake, the front end was clumping when I went over bumps, there was way too much play in the steering wheel, and the car is whistling while driving and idling. I took the car back on Thursday, July 6, 2006, the service writer drove it and instructed me to bring it back on Monday. At this time, my car is not fixed. The condition of my car has become substantially worse each time I picked up the car. It was 06/03/2006 when this power assist brake issue happened.
